Microbial community analysis in anaerobic palm oil mill effluent (pome) waste...eSAT Journals
Microorganisms play a key role in wastewater bio-treatment processes and understanding the microbial community structure is of great importance to improve treatment performance. Denaturing gradient gel electrophoresis (DGGE) was used to monitor succession of the microbial community and thus predominant bands were sequenced to reveal the microbial community composition inside palm oil mill effluent (POME) wastewater.DNA bands from DGGE gels were excised with a sterile blade and placed in 1.5 ml eppendorf tube containing 50 μl deionized water (ddH2O). Tubes were incubated overnight at 4C to elute the DNA. Eluted DNA was purified using QIAquick gel extraction kits (QIAGEN, Inc., Valencia, CA) and was frozen and thawed three times.Microbial DNA successfully excised and purified from DGGE was amplified using polymerase chain reaction (PCR).Five micro liters of the supernatant were used as a template to re-amplify the DNA using 16s rDNA primers,341f (with no GC-clamp) (5'- cct-acg-gga-ggc-agc-ag-3') and reverse(r) primers 907r (5'-ccc-cgt-caa-ttc-att-tga-gtt-t-3'). Amplification was repeated referring to the steps in ‘PCR amplification of 16s rDNA’. PCR products from agarose gels were cut and purified using QIAquick Gel Extraction Kit (QIAGEN, Inc., Valencia, CA), which were similar to the purification steps after recovery of DNA from DGGE, and sequenced in both directions with the same primers (with no GC-clamp) as used in PCR. Moreover, start-up is an important step in establishing proper community structure in all kinds of biological treatment processes. In anaerobic POME wastewater, 6 sequences of Firmicutes, 5 sequence of Proteobacterium and 2 sequences of Bacteroidetes were found through denaturing gradient gel electrophoresis (DGGE) results. Sequence closely related to Rummeliibacillus suwonensis strain G20 was detected grows at band BE10, BE11, BE12, BE15, BE16, BE17 and BE18. Meanwhile BE25 and BE26 were found at band after treatment process done.Rummeliibacillus suwonensis is an aerobic, Gram-positive, rod shaped, round-spore-forming bacteria which were isolated from aerobic condition. Keywords: Palm oil mill effluent (POME), anaerobic POME, Denaturing gradient gel electrophoresis (DGGE), and microbial community.

Evaluation of LdhIsozymes Following the Treatment of Methyl Parathion in the ...inventionjournals
Lactate dehydrogenase converts lactate into pyruvate and has a very important role in carbohydrate metabolism. LDH activity depends on its isozymes and their activities change under pathological conditions. The increase in LDH activity suggests the increased anaerobic conditionsunder the influence of methylparathion to meet the energy demand when the aerobic oxidation is lowered. Following the treatment of methyl parathion there was a differential percentage in increase or decrease of different isozymes in the fish Labeo rohita. There were three distinct bands during the 96h of treatment almost parallel to LDH5 band of human serum suggesting liver damage. This was also confirmed by histopathological studies.

Screening, optimization of production and partial characterization of alkalin...eSAT Journals
Abstract Bacillus strains isolated from the salteren pond (Kakinada) were screened and identified for high alkaline protease activity. The isolates which were positive on skim milk agar (1%) were selected as protease producing strains. Of the ten bacterial isolates screened, isolate S-8 was observed as a potential haloalkaline protease producer and it was identified as Bacillus cereus strain S8 (MTCC NO: 11901) by 16S rRNA gene sequencing, phylogenetic tree analysis and by different biochemical tests. Protease production was enhanced by optimizing the culture conditions. The nutritional factors such as carbon and nitrogen sources, NaCl and also physical parameters like temperature, incubation time, pH, inoculum size were optimized for the maximum yield of protease. Studies on the effect of different carbon and nitrogen sources revealed that maximum protease production was obtained in the medium supplemented with Molasses,1%(w/v); Potassium nitrate, 0.75%(w/v); salt solution- 5%(v/v) {MgSo4.7H2O, 0.5%(w/v); KH2PO4, 0.5%(w/v)}; FeSO4.7H2O, 0.01%(w/v) and CaCO3, 0.5% respectively. Thus, with selected carbon and nitrogen sources along with 1 % NaCl and 2% inoculum the maximum protease production (205.0 U/ml) was obtained in the period of 72 h incubation at pH-12.0 under 160 rpm when compared to the initial enzyme production (165.0 U/ml). The crude enzyme extract of this strain was also characterized with respect to temperature, pH, incubation period and different concentrations of casein which was used as enzyme substrate. This study shows that the enzyme has wide range of pH stability from 8 to 11 with optimum activity at pH-10.0. It is thermostable with optimum activity at 70°C (392U/ml) with 1h incubation of enzyme with 1% casein as its substrate. From the above investigations it was concluded that the protease production by these microorganisms at wide temperatures and pH ranges could be explored for varied industrial applications.

Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.

VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
