Thermal insulation coatings are a class which begins to attract more focus and priority in recent researches because of their importance and their numerous applications in different civil and industrial fields. In this research, the effect of nano alpha aluminum oxide (?-Al2O3) on the thermal insulation of polymer based paint was investigated. The different weight fractions of nano aluminum oxide ( 2%, 3%,4% and 5% wt. of polymer weight) were added to the formulation which contained nano titanium dioxide and nano calcium carbonate and poly vinyl acetate polymer solution . Dip coating technique was used to coat all samples. The highest increase in insulation value (R-value) was recorded for 4 %wt. sample where its improvement percentage reached to 24.42% compared with the sample which was contained no nano aluminum oxide addition while the other samples showed varied values. The microscopic images showed that 4% sample has well dispersed than others. The Knudsen diffusion effect is the proposed mechanism explaining the insulation improvement. - Seemore at:.

MACHINE LEARNING BASED NETWORK TRAFFIC CLASSIFICATION INCLUDING ZERO DAY TRAFFIC AS A CLASS. .
.. Support Vector Machines (SVM)represent one of the most promising Machine Learning (ML) tools that can be applied to the problem of traffic classification in IP networks. In the case of SVMs, there are still open questions that need to be addressed before they can be generally applied to traffic classifiers. Identifying and categorizing network traffic by application type is challenging because of the continued evolution of applications, especially of those with a desire to be undetectable. The diminished effectiveness of port-based identification and the overheads of deep packet inspection approaches motivate us to classify traffic by exploit To tackle this critical problem, we propose a novel traffic classification scheme which has the capability of identifying zero-day traffic as well as accurately classifying the traffic generated bypre-defined application classes. - See more at:

ENHANCED ENERGY EFFICIENT CLUSTERING PROTOCOL FOR WIRELESS SENSOR NETWORK. - .
Energy hole problem is one of the main problem in Wireless Sensor network. Sensor nodes near the sink acts as a relays because they are forwarding their data as well as sensors are far away from sink. Hence Energy depletion is faster in convey nodes. Suppose all the relay nodes die, far sensors can’t communicate to the sink node even though they have Energy and data. This is due to Energy holes. To overcome this problem Mobile sink is used. Finding the path of mobile sink is a hard task. In this paper Mobile sink-based Adaptive Clustering Protocol [MSIEEP] is enhanced to improve the network lifetime.

CLIONA VIRIDIS: MINERAL COMPOSITION AND CONTRIBUTION TO THE ASSESSMENT OF THE QUALITY OF THE MARINE ENVIRONMENT.
The lifestyle and aquiferous system of sponges are the main factors behind their structural characteristics. They are capable of filtering large volumes of water and have a high rate of retention for particles of 0.2 to 50 microns (µm) and therefore a large capacity accumulation of pollutants. At the same time, members of all sponge classes (Demospongea, Sclerospongea, Hyalospongea) can secrete mineral elements called spicules of opaline silica. These siliceous spicules constitute their skeletons involved in several functions, namely in defense, support and the like. Cliona viridis is chosen for the study of mineral composition, and contribution to the evaluation of the quality of the marine environment by measuring the concentration of certain heavy metals in two different zones. Silica SiO2 is 70.99% (± 0.23) of the biomass of the sponge with other minerals such as sodium, chlorine and calcium. The zinc (Zn) is the most accumulated metal then Iron (Fe) and aluminum (Al). A large study with several species collected from different areas will allow us to understand the process of accumulation of silica and heavy metals and have a good image of level of contamination of the marine environment. - See more at: .

OVERLAPPED WATERMARKING FOR SECURED DATA TRANSMISSION..
A high efficiency multi-layer halftoning based watermarking which adopts noise-balanced error diffusion to achieve high embedding capacity and improve security aspect. The encoder employs an Efficient Direct Binary Search (EDBS) and Look-Up-Table (LUT) method to embed multiple watermarks. The decoder simply utilizes the Least-Mean-Square (LMS) and naive Bayes classi?er to extract the embedded watermarks in multi-layer framework with self-decoding capability. The proposed watermarking preprocesses the watermark to reduce its bit depth. The 8-bit grayscale image (with 256 levels) is converted into a new image representation (with a lower bit depth) using the uniform scalar quantization with ?xed divisor. The distance metric can be considered in determining the quantization. Experimental results suggest that only minimum milliseconds are required for embedding multiple watermarks. - See more at:

RSA Cryptography Algorithm Using linear Congruence Class..
Due to the enormous demand for networking services, the performance and security of information has to be improved. To provide information security, numerous cryptographic algorithms were proposed by various researchers, out of which RSA algorithm is one the most popular algorithm. RSA algorithm uses linear congruence method which restricted the operation to specific class of values. RSA algorithm needs exponential time for decryption of message. By extending the RSA algorithm using congruence class and selecting the key in random, the security of algorithm can be increased. Higher the congruence class index, higher will be its level of security. For each of the congruence class element, complexity of algorithm will be same but there will be increase in the level of security. The basic idea behind this implementation is that by converting the given linear congruence into congruence class and solving them algebraically, actual information can be produced. This paper contains the comparison between linear congruence and congruence class using RSA algorithm. Finally we contend that, due to congruence class implementation, the complexity of algorithm will remain same as that of regular RSA algorithm with enhancement in information security by random congruence class key selection. - See moreat: .

EQUALITY IN SOFT EROSION, SOFT DILATION AND SOFT OPEN IN MULTI SCALE ENVIRONMENT.
-. In this paper, equality is established and discussed among soft erosion, soft dilation and soft open in multi scale environment. Soft erosion and soft dilation will exist for various thresholds. So soft open and soft close also exist for various thresholds. If definition for soft erosion and soft dilation are studied (5 ),then some type of equalities are viewed among soft morphological operations. So equality may be established in between soft erosion and soft dilation in multi scale environment (39). open and close are composite operations. So soft open and soft close are also composite operations which will exist at various thresholds. So equality may be viewed among soft erosion, soft dilation and soft open . This discussion may be extended to multi scale environment also. A very important point is that equality does not exist in mathematical morphology but will exist in soft mathematical morphology. - See more at:
EVALUATION OF ABSORPTION AND CAUSTICIZATION OF CARBON DIOXIDE SCRUBBED CHEMICALLY FOR SEQUENSTRATION.
. Climate change and its effect on Indian monsoon in recent years is now having adverse effect on agriculture and less production of grains, vegetables and other life commodities. Various anthropogenic sources are responsible for climatic variations and atmospheric environment pollution. It was recognized in the early 20th century that the known major greenhouse gases in the atmosphere caused the earth\'s temperature to be higher than it would have been without the greenhouse gases. Foundry industry being more in number at Maharashtra especially Kolhapur City is playing very important role in emitting Carbon Dioxide (CO2) and other pollutant due to use of Coke as a fuel for combustion in foundry industry. Cupola technology in casting industry releases more Carbon Dioxide through the stacks which leads to Global Warming. Hence it is necessary to capture and store the emissions of Carbon Dioxide before its release into atmosphere and reuse whenever necessary. This paper envisages application of Carbon Capture and Sequestration (CCS) by chemical absorption technology which further elaborates how efficiency of carbon capture in foundry can be increased and thereby optimizing the chemical reactions in the process. - See more at: .

Study on FR Mechanism for User Privacy Protection on Social Networking Websites: An Overview. .
As the technology is progressing day by day, so is the numeral of safekeeping issues related to online social networking sites are growing. In this era, online social networks (OSNs) have prolonged a lot of fame around the globe. The OSN users share photos, videos and countless similar media, which at times are a big privacy issues for other users on OSN’s. The privacy fears rise while certainusers update information of other users on social networking websites, which can be immaterial, or somebody wanted it to hide from others or kept it undisclosed. Such sort of information maycomprise of users images, his/her status updates, his/her videos, etc. The main objective of study of this paper is to deal with various kind techniques that can be used to solve the problem of safety related concerns of online social networks. The whole emphasis has been curiouslyplaced on the multiple entity-based images shared by the users, which comprise of privacy related issues. From the time when the decision on photo posting includesgroups in the circle (the most likely scenario) and it is dispersed in nature, our difficulty can be distorted to be a characteristic secure multi- party computation problem. Instinctively, we may ask cryptographic technique to protect privacy related issues, but the computational and communication cost may pose a severe problem for a large Online Social Networks. Apart from cryptographic approach, we may take the consensus-based approach as a promising alternative. The idea to let both user only deal with his/her local data and get the local training result, and then the neighboring users only need to exchange their training results. In the following round, each user still works on his own training data, but take the training results from his/her neighbors as references. We assume that the information will be spread over the OSN and everybody involved will extendthe same conclusion. - See more at: .

STUDY OF POLYMETALLIC MINERALIZATIONS ASSOCIATED WITH ARCHEAN METABASITESOF AMSAGA (RGUEIBAT RISE, MAURITANIA) - .
. The Amsaga Zone is of a major importance, due to its position in the extreme south west of the Archean part of the Rgueibat shield, particularly to its location close to the Akjoujt Copper mine. Some dating migmatites indicate that granulite metamorphism affecting most Amsaga units took place between 3 and 2.7 Ga. The field observations and microscopic study of samples analyzed of metabasite have helped to understand the relationships between lithological units and mineralization control structures such as faults and shear zones. This context reflects a tectonic control of implementation of the mineralization by movements in faults and in ductile shear zones. The implementation of the copper mineralization could be either syngenetic, related metamorphism or hydrothermal fluid circulation, or it is late in relation hydrothermalism associated with panafrican and hercynian orogenies of Mogrein Guelb deposit, Akjoujt south of Amsaga. - See more at.

Synthesis and Characterization of Ternary Copper(II) Complexescontaining L-Valine. Catechol Oxidase and Phenoxazinone Synthase Biomimetic Catalytic Activity. - .
. A new series of ternary copper(II) complexes having molecular formulae [CuLL?X] and [CuLL?]X has been synthesized. For this ligand system LL?, L is the amino acid L-Valine and L? is 2-aminomethyl pyridine while X¯ is Cl¯, Br¯, NO3¯, ½SO42- or ClO4¯. The structure characterization of these newly synthesized copper(II) complexes was achieved by various physicochemical techniques, viz. elemental analysis, Thermal analysis (TGA and DTG), magnetic susceptibility measurements, IR, electronic, and EPR spectral studies. The spectral and magnetic measurements in addition to the electrolytic conductance results indicate that complex2is five -coordinate square pyramidal while the other complex species are found to have four-coordinate square-pyramidal geometry. It has been shown that the stereochemistry of complexes is dependent on the type of counter anions incorporated in the complex molecule. The kinetics and mechanism of substitution by thiourea (TU) were studied in detail as a function of nucleophile concentration in methanol as solvent. The kinetics showed that the substitution reaction of all complexes is a biphasic process. Mimicking copper-oxidase enzymes namely catechol oxidase and phenoxazinone synthase was investigated and the results obtained demonstrated that, the reported copper(II) complexes are suitable as catalysts for the catalytic aerobic oxidation of 3,5-di-tert-butylcatechol(3,5-DTBCH2) to 3,5-di-tert-butyl-benzoquinone (3,5-DTBQ) (catechol oxidase activity), and o-aminophenol (OAPH) to 2-aminophenoxazine-3-one (APX) (phenoxazinone synthase activity) with dioxygen at ambient condition in good yields. - See more at:

Positively charged Hydrogen atom(H+) different from Proton (p+): Proposed model for constituent particles in positively charged Hydrogen atom(H+). - .
Normally it is believed that when a hydrogen atom looses one electron, it can be termed as proton. Here it is suggested that though after the loss of electron from hydrogen atom a positively charge nucleus is left behind but that positive charge is due to positron. On the basis of literature available, a model is proposed showing constituent particles of positively charged H atom. This model states that a hydrogen nuclei consists of neutron, positron and neutrino. A neutron consists of a proton, electron and anti-neutrino. Therefore a positively charged Hydrogen atom(H+) is different from Proton (p+). - See more at:

Study of some requirements of the environmental management system at the test-work facilities of the Egyptian black sands at Abu Khashaba and Rasheed. .
The second requirement was to evaluate the emission of radioactivity from the studied facilities to the surrounding environment. It was very difficult to relate any change in the external effective dose rate received by the public around the facilities to the radiation activities inside these facilities. On another hand, the excess radon gas concentration at the downstream of Abu Khashaba and Rasheed facilities was found to be 1 and 3.57 (Bq/m3), respectively. These excess concentrations resulted in an increase in the annual effective doses of 0.025 and 0.092 (mSv/y) at Abu Khashaba and Rasheed facilities, respectively. The additional effective doses received by the members of public around the studied facilities are much below the recommended dose limit of 1 (mSv/y). Two requirements of the environmental management system at Abu Khashaba and Rasheed facilities were evaluated. The first requirement was the quantities of sands processed at both facilities. A total mass of 3509 (tons) was processed at Abu Khashaba facility representing a total radioactivity of 2.57x109 (Bq) while a total mass of 1973 (tons) was processed at Rashedd facility representing a total radioactivity of 5.97x109 (Bq). The majority of radioactivity at Abu Khashaba facility comes from raw sands while the majority of radioactivity at Rasheed facility comes from monazite mineral. This strongly suggests the establishment of an efficient marketing plan to displace monazite from Rasheed facility. The study recognized an efficient plan to displace the waste sands from Abu Khashaba and Rasheed facilities. It is concluded that the radiation activities at the studied facilities are consistent with requirements of environmental safety. - See more at: .

In El Missikat tunnel, the average activity concentration of radon gas was 13.9±5.5 (kBq/m3) at the studied non-venilated locations and 1.69±1.07 (kBq/m3) at the ventilated locations while in El Erediya tunnel the average radon concentration was 5.77±2.59 (kBq/m3) at the non-ventilated area and 1.19±0.4 (kBq/m3) at the ventilated area. Thoron gas concentration got an average value of 3.83±2.3 (kBq/m3) at the non-ventilated locations inside El Missikat tunnel and 247±49.75 (kBq/m3) at the ventilated locations while in El Erediya tunnel this gas got an average concentration of 0.61±0.26 (kBq/m3) over the non-ventilated area and 0.3±0.2 (kBq/m3) over the ventilated area. Indeed, the concentrations of radon and thoron gases obtained by the two-compartment detector responded well to the concentrations of 238U and 232Th in the studied granitic rocks and they differentiated precisely between the ventilated and non-ventilated locations. On another hand, the detector showed linear response of accepted correlation between uranium and thorium concentrations and the effective doses due to the inhalation of radon and thoron gases and their decay products inside the studied tunnels. This, along with the easy use, light weight and small dimensions qualify the proposed detector as an individual monitor of radon and thoron gases for the workers in uranium mines. - See more at:.

Harmful Chemicals: Impact on Environment.
Role of Chemicals in human life is very important. They are essential and have adverse impacts on the environment,which has a direct relation with all living things. The three essentials for any life Air , Water and Food which constitutes our environment, are being polluted / adulterated. Our environment is having majority of chemical substances due to various humans activities. It is not the case of today but of the past as well. The difference only lies in the ratio of population verses environment, which is increasing day by day. As a result, there is a direct impact on the physical and chemical environment. These chemicals are the waste from industrial and agricultural processes, structural materials, pesticides, insecticides,weedicides etc.It is evident that some chemicals are useful but many are toxic and harm the environment and our health. A human activity has a complex impact on the environment and affects a chain of interconnecting ecosystems. Use of safe and useful chemicals not only minimizes the risks occurring in the environment but also in human beings. - See more at:

Hydro-morphology of Cuts in Coastal Rivers debouching Chilika; South Mahanadi Delta, Odisha, India .
Bhargovi, the split deltaic branch of southern Mahanadi River, runs parallel to Bay of Bengal for last 48.5km and debouches in the northern swamps of Lagoon Chilika joining branch Daya. Though not wide, the river discharges 1100 to 1450cumec which is 3-4% of floods of river Mahanadi. Proximity to coast, alluvial flat topography, sinuosity and mild gradient posed a constant threat to lives and property. Early release of floods to lessen havoc to Puri district during early 20th century was considered urgent. Three cuts were officially provided in the Bhargovi system at. Mangala cut (1937), Siaro cut (1942) and Gabakund cut (1984-2007). After Gabakund cut in 2007, Chilika received 70% less flow of Bhargovi. Sedimentation and imbalance in the flow exchange downsized lagoon area. Each cut plugged one river and made them geriatric or defunct. The present paper studies the spatial impact of these cuts. Stochastic modeling with regression analysis is done to establish a relation between the stages of Gabakund cut vs. discharges at delta head by considering travel time. Field observations are taken to predict the impact of the submerged weir and pilot channel after renovation of cuts. - See more at: .

COMPARATIVE STUDY OF EQUATION OF STATE FOR SOME IONIC CRYSTALS. .
The phenomenological forms for isothermal equations of state (EOS) of solids have played a very important role in the field of high-pressure physics. An isothermal EOS is used to study the relationship between pressure P and volume compression at a given temperature. It is also used to study the isothermal bulk modulus BT and its pressure derivatives B`T and B``T, respectively. In the present study we have taken five different forms of EOS which contain B 0 and B`0 only. Using these forms we have studied the pressure-volume relationships for MgO at room temperature and at different range of temperatures. The results for pressure P, isothermal bulk modulus BT and pressure derivative B`T obtained from different equations are compared. The comparison reveals that the all EOS yield very similar results. - See more at: .

Experimental investigation of multi cylinder S.I. Engine emissions by using oxygen enriched air - .
This research paper gives an explanation of the formation process of toxic exhaust gas components during combustion process of oxygen-enriched mixtures in SI engine. Emissions from the exhaust of internal combustion engine affects the environment globally and also it has negative impact on human health.. Various strategies have been being developed to regulate the pollution in the urban development. Increase the concentration of oxygen in the intake air is also one of the methods to reduce emissions of CO and HC. In order to reduce the emissions the oxygen was supplied at different flow rates i.e.at 3lpm, 6lpm and 9lpm.Investigation work shows that carbon monoxide(CO) emissions decreases at increased amount of oxygen concentration in the intake air but at the same time carbon dioxide (CO2) emissions increases due to proper combustion in the combustion chamber. - See more at: .
IMPACT OF SDR FLUCTUATIONS ON INCYLINDER FLOWS BY VARYING PISTON BOWL CONFIGARATIONS. -
. t is known fact that the CI engine combustion process is extremely complex. By modeling the In-cylinder processes by suitable combination of assumptions and equations we can analyze the critical features. The CFD models gives us complete understanding of the process under study from formulating the model, controlling the key variables giving rise to cost reduced and time consuming experimental methods. The CFD code used in the present work is FLUENT. FLUENT is very much useful in modeling In-cylinder flows and gives better analysis of pollutants. All the codes run with their own assumptions and restrictions. In this code, it is found that the scalar dissipation rate fluctuations (SDRF) has been ignored which may cause inconsistency in the results. Hence this work is proposed to account SDRF and possible inclusion in the existing code. Three piston bowl configurations spherical, Mexican hat bowl (MHB) and Mexican hat bowl with lip (MHB with Lip) is considered in the present work. The results were presented in the form of graphs with and without considering the effect of SDRF. The validation of the results is done by comparing with the available experimental data. - See more at:.

MAGNETIC FIELD EFFECT ON THE METABOLISM AND ENZYME ACTIVITY IN SOME HARMFUL INSECTS
. Effect of the magnetic field on the physiological aspects of some insects was studied for larvae of three insects reared in laboratory under 25 ±2°C and 70 ±5% RH in suitable rearing boxes. An experimental set-up was designed to measure the magnetic flux density in the rearing box. The magnetic field was calibrated to obtain the point of the maximum gradient. Magnetic flux density was measured using a Tesla meter and recorded average values of 21.8, 249 and 863 Gauss (G) for the 3 insects respectively. The three insects were: cotton leaf warm, S. littoralis, red palm weevil, R. ferrugineus and the greater wax moth, Galleria mellonella. Rearing insects started with a suitable larval instar. Numbers of larvae (form each insect) divided into 2 similar and equal groups, the first reared as a control (without magnetic field), while the second group was exposed to the magnetic field, (MF) along rearing periods. An appropriate numbers of larvae from the control and the treated ones were taken for Bio-chemical analysis and the main parameters were recorded. The measured physiological parameters were: total protein, total carbohydrates, total lipids, invertase enzyme and alkaline phosphatase. Results showed that each of body weight and growth rate as well as the physiological aspects was affected with the magnetic field. Rate of growth was negatively affected as it decreased in cotton leaf worm and red palm weevil. Results also demonstrated that invertase enzyme decreased in the treated larvae of S. littoralis ans G. mellonella with 40.15% and 28.33% respectively lower than the control. In the same time, magnetic field led to increase the invertase enzyme in R. ferrugineus with 71.6% higher than the control samples. In spite of the strong magnetic flux around the larvae of G. mellonella their influence was limited. This may be due to the special behaviour of the worms as they of internal presence and entrance inside the rearing media for these larvae. - See more at: .

- . Money, which is responsible for solving health problems, can be turned out as a cause of creating health problems. Paper currency, an exchangeable fomite, is constantly subjected to contamination. The objective of this study was to identify the bacteria present on the currency notes circulating in India. A total of 50 currency notes of different denominations (Rs. 5, Rs. 10, Rs. 20, Rs. 50, Rs. 100, and Rs. 500) were randomly collected from 15 different sites like ATM, auto driver, bank, beggars, bus conductor, butchers, college canteen, food seller, general store, medical store, milk dairy, petrol pump, rickshaw puller, vegetable/fruit sellers and wine shop. Persons handling the notes were asked to deposit them in sterile polythene bags. The notes were taken to the laboratory immediately and bacteria were identified using standardized microbiological techniques. 96% of the notes (except ATM notes) collected during this study were contaminated with bacteria like; Bacillus sp., Staphylococcus sp., Streptococcus sp., Corynebacterium sp., Clostridium sp., Escherichia coli, Actinomycetes sp., Klebsiella sp., Pseudomonas sp. and Salmonella sp. The study suggested that Indian paper currency notes are highly contaminated with pathogenic bacteria and this may play a significant role in transmission of infectious diseases. Hence, great care must be taken while handling money during the preparation and handling of food to avoid cross contamination. - Seemore at:

LARYNGEAL MASK AIRWAY FOR MINOR ORAL SURGICAL PROCEDURES: A CLINICAL STUDY.
Laryngeal mask airway (LMA) has been used for many surgical procedures by the anaesthetist in general surgical procedures. It is seldom applied for oral surgical procedures. In this study we have used LMA for common minor oral surgical procedures. A total of 30 patients who required short oral and maxillofacial surgical procedure of all age group were included. Pre anaesthetic evaluation and physician fitness, as required was taken. Time taken for insertion was noted. Duration of surgery from the time of laryngeal mask airway insertion till the removal of laryngeal mask airway was recorded for all cases. Post operative dysphagia and dysphonia was evaluated by visual analogue scale and ease of placement also was evaluated with visual analogue scale. For most of the cases time taken for insertion of LMA was between 120 to 150 seconds. Only one case took around 4 minute of time for insertion and 3 cases took more than 1 hour duration for surgery. There was mild dysphagia and dysphonia after 24 hours and no other related complications were noted. Final conclusion of this study was that LMA can be used in minor oral surgical with minimal complications. - See more at: .

DEVELOPMENTAL MILESTONES OF INFANTS ADMITTED TO FACILITY BASED NEWBORN CARE UNIT: A CASE CONTROL STUDY. .
Introduction:- Facility based new born care has been identified in treating sick child and providing support to low birth weight babies immediately after birth. This care is crucial in determining the child survival. Developmental milestones act as check points in a child’s development to determine what the average child is able to do at a particular age. Facility based care includes essential care at birth and care of sick babies which helps infants to grow at normal rate and live a healthy life. This study was an attempt to compare normal infants and infants admitted in FBNC units. Methodology:- The present study was undertaken to evaluate the developmental milestones of infants admitted in Facility based new born care also called Special New Born Care Unit at the time of birth, in Sawai Madhopur District. Data for infants born were taken from ASHA and AWW by investigators. The total infants tracked for the study were 2888, 1444- admitted to FBNC and 1444 from normal population were matched for age and gender from the same village. An Interview schedule was formulated to collect general information. Information related to developmental milestones like age of social smiling, neck holding, standing etc were recorded. Results: - The results of the study indicate that there was no significant difference in the 2 groups (FBNC and Normal) with regard to cognitive development. Ninety percent infants in both groups gave social smile at one month, neck holding at 3 months was seen in around 37 % in both groups, standing with support at 9 months was seen in 22 % infants and 4 % infants at 1 year, similarly speaking monosyllables at 9 months was around 20 % and at 1 year it was 4 % in both the groups. Although there was no significant difference between the 2 groups but with regard to cognitive development the indicators were not up to the acceptable standard of development according to age. - See more at: .

Healthy root formation was observed in all microshoots following two weeks of transfer on half-strength MS medium containing 0.5 µM ?-naphthalene acetic acid and 0.5 µM Indole acetic acid. These plants were subsequently transferred to pots containing a mixture of soil, sand and farm yard manure (2:2:1, v/v), and then shifted in the greenhouse. In the green house and the overall survival was found to be 75% after 2 months. The genetic fidelity analysis of S. brevistigma plants developed from encapsulated microshoots was done using random amplified polymorphic DNA (RAPD) marker. For molecular analysis 25 decamer primers were used to check genetic fidelity of plants selected from all three batches was carried out using. Only 5 primers produced scorable amplified products and a total of 38 bands were observed; out of these 10.52% bands were polymorphic. Cluster analysis of the RAPD profile revealed an average similarity coefficient of 0.95 confirming genetic stability of plants derived from encapsulated microshoots following 1 months of storage at 25°C. - See more at: .

... Autophagy-related Protein LC3 in Egyptian Colorectal Cancer: Impact and Possible Relation to STAT3 andmiRNA 101..
Background: - Colorectal cancer (CRC) is a common worldwide cancer and the fourth worldwide cause of cancer death. Autophagy has been highlighted as a promising molecular target in cancer. Its role in carcinogenesis is complex with a reported oncogenic or tumor suppressive role. Detecting LC3 has become a reliable method for monitoring autophagy. Signal transducers and activators of transcription (STAT) proteins are latent cytoplasmic transcription factors. MicroRNAs (miRNAs) are small non-coding RNAs which post-transcriptionally regulate gene expression. Aim:- To search for the expression of LC3, as a marker of autophagy, STAT3 and miRNA 101 as possible regulators of autophagy and/ or potential molecular prognostic targets in Egyptian CRC patients. Material and methods:- Twenty five CRC and 25 adjacent normal mucosa specimens were obtained. Immunohistochemical assessment of LC3 expression using anti-LC3 and assessment of STAT3 and microRNA 101 expressions by real time - RT - PCR were done. Results: - Revealed a statistically significant increase in LC3 (p<0.001) and STAT3 expression in tumor samples (6.31 ± 1.96 folds) than normal mucosa (p<0.001 each). Both of them were directly correlated together (r= 0.833, p <0.001). MicroRNA 101 was inversely correlated to both LC3 and STAT3 (p<0.001) and was significantly reduced in tumor samples (0.37 ± 0.16 folds) (p<0.001) with a possible correlations to tumor characteristics. Conclusion:- LC3, STAT3 and miRNA 101 may be valuable as biomarkers that may predict cancer colon poor prognosis. The critical role of STAT3 and miRNAs in autophagy would expand our knowledge of the molecular mechanisms of autophagy regulation. - See more at: .

FUNGICIDAL PROPERTIES OF HIGH ALTITUDE MEDICINAL PLANT: AN ANTIFUNGAL SUBSTANCE FROM THE EXTRACTS OF SELECTED MEDICINAL PLANTS.
The aim of this investigation was to evaluate the antifungal activity of extracts of 11 different medicinal plants species from Trans-Himalayan region against the phytopathogenic fungus Aspergillus niger and Aspergillus flavus. Methanolic extract of Codonopsis clematidea, Hippophae rhamnoides, Artimesia dracunculus, Galium aparine, Mentha longifolia, Foeniculum vulgare, Rubia coradifolia, Saussurea lappa, Inula racemosa, Rheum webbianum and Arnebia euchromawere screened for its antifungal activity. The plants were selected on the basis of their reported ethnobotanical uses and locally available. Results revealed that all the concentrations of plant extracts brought about significant inhibition in the growth of these pathogenic fungi Aspergillus niger and Aspergillus flavus. All the three concentrations of the 12 tested plant extracts were found to be significantly inhibitory to fungal growth and the rate of inhibition increased generally by increasing the concentration. Similarly antifungal activity of plant extracts showed significant activity when compared with the leaf/root extract against the two Aspergillus spp. The results indicated that all tested plant extracts had different degrees of antifungal activity against the tested pathogenic fungi. Hence, the objective of this study was to determine if plant extracts could provide antifungal activity against some plant pathogenic fungi. The results obtained from the present investigation clear that the antifungal activity vary with the species of the plants, plant material and the concentration used. - See more at: .

EXPERIMENTAL STUDIES ON L- LACTIC ACID FROM GROUNDNUT SHELLS BY USING LACTOBACILLUS delbrueckii NCIM 2025 AFTER PRE TREATMENT. .
In pursuit of selecting cheap raw material for producing lactic acid by fermentation ground nut shells were chosen as substrate. However there is no much relevant information was available on fermentation of ground nut shells. The experimental studies on production of L lactic acid were explored, by solid state fermentation. The experiments on groundnut shells were carried out, as substrate which was one of the cheapest raw materials available in India. The ground nut shells were pretreated with dilute acid (HCl&H2SO4), sodium sulphite, NaOH and methanol solvent extraction methods for producing total sugar. It was observed at temperatures ie., at 350C,370C and 420C, different inoculums size(3ml to 6ml) and different pHs(4.5 to 5.5), the lactic acid production is 12 g/l, `17 g/l and 23.0 g/l respectively. Lactic acid was estimated by AC Kimberley Taylor method. The mutant cells were tested for its stability on 0.6% Allyl alcohol , which was a selection agent. Mutants were generated by exposing to UV radiations, with different exposure times and stability is tested. The results were encouraging and the lactic acid produced was about 23 g/l at temperature of 420C. The pH optimum was found to be about 5.2. and inoculum size was found to be 3 ml. The present studies were focused on accumulation of lactic acid by using ground nut shells having ligno cellulosic material after treatment with dilute acid. - See more at:

AN OBSERVATIONAL STUDY OF EMERGENCE REACTIONS OF KETAMINE ANAESTHESIA IN RELATION TO DEH-PRAKRITI. - .
Prakriti takes its origin at the very moment of the fertilization of the Shukra with Shonit where the predominance of particular Dosha determines the Prakriti. Every individual has some specific physical and mental qualities which remains same throughout the life. The examination of the individual is essential while administering medicines. It is of utmost clinical importance to ascertain the degree of patient’s strength by knowing the tone of the system, compactness, body proportion, state of mind, digestive power, tolerance to exercise and age. The determination of all the above factors may reveal the incidence of emergence reactions found with Ketamine anaesthesia. This analysis on the basis of Deh-Prakriti may decide the particular constitution in which these emergence reactions are common. In this way it would be possible to take precautionary measures pre-operatively in particular patients and thus prevent these worrisome psychological reactions. - See more at:
