Single Cell Protein (SCP) can be obtained from various microorganisms by growing them on a number of types of substrates, including industrial products waste. This work focuses on non-conventional yeast Yarrowia lipolytica, and its application in the process of production of valuable components like SCP and amino acids. It also analyses the possibility of using obtained biomass as a dietary supplement for humans. Y. lipolytica is nonpathogenic to humans and has been approved for use in several industrial processes as it is generally recognized as safe (GRAS). The results of our analyses suggest that the Y. lipolytica A-101 – a strain growing in biofuel production waste is a good candidate for a source of high-quality yeast protein (40-50% of dried biomass) and exogenous amino acids (phenylalanine 3.9 g, isoleucine 4.4 g, leucine 6.8 g, lysine 7.0 g, methionine 1.2 g, threonine 4.8 g, tryptophan 4.7 g, valine 5.3 g/100 g of protein). Y. lipolytica A-101 biomass has also very low nucleic acids concentration (below 1%) due to activation of endogenous nucleases in the final stage of the stationary phase. These enzymes reduce the amount of nucleic acids in this biomass from a high level to one acceptable for human consumption. Moreover, Y. lipolytica A-101 biomass is safe and digestible since the yeast cells get killed in the drying process and has no leavening powder with destroyed cell wall. Y. lipolytica A-101 can be used as a nutritional supplement in human diet when an increased intake of amino-acids and SCP is required.

In the current study, the effects of three types of additive (lime, cement and
cement kiln dust) on the plasticity of a soil are studied. The results of the study
indicate plasticity index are affected by the addition of (cement, lime and cement kiln
dust) and the effectiveness of these additives depends on the soil treated and the
amount and type of additive used. The main results show that with increase of
Additive the plastic limit increases and liquid limit decreases, hence decreases
plasticity index and it is revealed that a change of soil texture takes place. While
Addicrete BV does not effect on the Atterberg limits or the soil texture of the soil.
Then the plasticity properties of the soils including liquid, plasticity and shrinkage
limits as well as plasticity index were investigated and compared among the
specimens in different mixture proportions. Atterberg limits (Plastic limit “PL”,
Liquid limit “LL”, and Plasticity index “PI” = LL-PL) play an important role in soil
identification and classification.

It is widely accepted that a safe and healthy workplace is key to ensure
employee engagement. As manufacturing organizations are more prone to industrial
accidents, the study focuses on the different employee health and safety initiatives
taken by several garment factories of Dhaka, Bangladesh. The study uses both
primary and secondary data. A complete questionnaire was set for personal
interview. OHS manual, audit reports, websites, journals, Labor Act 2006, text
books, gov’t publications etc. are among secondary source used. Finding of the
study does not portray something very good. Existence of short and poor quality
policy, unfurnished medical room, same happens with the first aid boxes, problems
with temperature, ventilation, noise and lighting etc. are most common
complications. Although the government has taken several actions along with
international bodies, effectiveness of those activities is questioned. A unique
guideline for safety improvement, training arrangement for employees, close
monitoring of safety and health issues can prove very effective. There is urgent need
for consorted action in the sector that envisions a decent work environment.

This paper describes the application of experimental design techniques to
characterize the wear behavior of two medium carbon steels designing with suitable
alloying elements, Mn, Si, Al, and Cr. Application of experimental design technique
enabled us to confirm the significance of the factors affecting the wear behavior with
a minimum number of experiments. Attempt was to find out the dominant parameter
on the wear behaviour. The experiments of sliding wear were performed under
pressure range of 0.71- 1.98 MPa and sliding velocity range of 3.43-10.43 m/s. the
wear specimens were obtained through hot forging process with ~ 92% reduction on
the investigated alloys at a temperature of 1100 0C followed by air cooling.
Microstructural investigations on the worn surfaces were undertaken. The
morphology results and the general wear formulas reveal that applied pressure was
found to be the most significant parameter.

Tumors of the central nervous system represent a heterogeneous group of tumors with a varied histopathologic spectrum and a variable frequency. In this study, we retrospectively analysed the epidemiological and the histopathological data of central nervous system tumors collected in our department. This study includes 657 central nervous system tumors histologically diagnosed from 2004 to 2016. It concerns all CNS tumors according to the WHO classification. The characteristics of patients, including age, sex, location, and histologic diagnosis were analyzed. Tumors were equally seen in males and females (sex-ratio=0.99:1). The mean age at the time of diagnosis was 38 years. 24% were children and teenagers. The commonest location was intracranial (92.3%). The primary tumors accounted for 92.8% of CNS tumors. Tumors were benign in 53.5% and malignant in 46.5% of cases. The most common histologic type is astrocytic tumors (30%), followed by meningeal tumors (26.7%). In adults, the three commonest categories were meningothelial tumors, astrocytic tumors and oligodendroglial tumors. For children and teenagers, astrocytic tumors were the most prevalent, followed by embryonal tumors and ependymal tumors. There was a male predominance for astrocytic, ependymal and oligodendroglial tumors and medulloblastomas. In contrast, meningiomas and schwannomas were more frequent in female. The most frequent intracranial tumors were astrocytic tumors, meningeal tumors and embryonal tumors. In spinal cord, meningeal tumors, schwannoma and ependymal tumors were the most prevalent. In the absence of a national register of CNS tumors in Morocco, we performed this study which may reflect epidemiological and histopathological characteristics of these tumors in our region. Globally, our results were in accordance with those of other studies around the world. However, we noted a higher proportion of tumors in children and teenagers

Labor union is one apex body of labor which is established with the
purpose of advocacy and bargaining for the rights and benefit of labor. Union itself
is power which can discuss with government and non-government organization for
the betterment of labor. The labor union advocates on the different types of needs
and right of labor, but the study has explore the role of labor union in promotion of
physical facilities for workers of manufacturing industries of Bara and Parsa
district of Nepal. In total 385 workers were selected randomly for the structured
questionnaire survey. The statistical analysis of eight indicators measured in the
field to know the status of physical facilities shows that in total only 39.68%
workers agreed that labor union had played the effective role to manage the
physical facilities for labor union which is not satisfactory result on the basis of
objective of labor union. So, the role of labor union should be more effective and
need to develop the new strategy of their action.

In present study an attempt has been made to study the antimicrobial activity and chemical composition of leaves and flowers of Spilanthes acmella. The leaves and flowers of the plant were collected and subjected for study of their chemical composites and antimicrobial activity of their extracts. The samples were given the code SALS1, SALS2 and SALS3 and SAFS1, SAFS2 and SAFS3 respectively for the extracts of leaves and flowers. The crude extracts of leaves and flowers were prepared by using various solvents like Petroleum ether, Ethanol and double distilled water. All the extracts were used to study their antimicrobial activity against gram positive bacteria eg. Bacillus subtilis, gram negative bacteria eg. E. coli and K. Pneumonia and anti-fungal activity against Aspergillus Niger. The chemical composition of leaves and flowers like Dry matter, Total ash, Ether extract, Crude fibre, nitrogen, Crude protein, Total carbohydrates, Nitrogen free extract and Organic matter were studied. The results of antimicrobial activity revealed that all the crude extract samples of leaves were found to possess antibacterial property. Maximum inhibition was shown by all the three samples against E. Coli and K. Pneumonia. However the maximum inhibition of growth of E. Coli and Bacillus subtilis was shown by SAFS1 and SAFS2 respectively. All the crude extracts of samples shown antifungal activity against Aspergillus Niger. The samples of leaves were found to be more effective than flowers against the fungal strains of Aspergillus Niger. In present study it has been concluded that the leaves may be used against the infectious diseases caused by E. Coli, K. Pneumonia and A. Niger as herbal medicine

An Economic Model of Foreign Language Learning and Its Implications for Econometric Analysis
Yanqing Jiang, Xianru Ge
Page no 1189-1200 |
10.21276/sjhss.2017.2.12.5
In this paper, we build a formal, rigorous economic model for foreign
language learning, taking language input and language output as two crucial factors
working jointly to generate language competence. The central idea behind our
model is that the learner, constrained by limited resources, is confronted with a
tradeoff between input-oriented training and output-oriented training. First, one
major contribution of our modeling lies in its effort to reconcile the Input
Hypothesis with the Output Hypothesis in the literature by showing that one
important aspect of the learner’s learning strategy, i.e. the input-output mix, is
crucially dependent on the learning environment. Second, our modeling provides
guidelines for data based empirical research, where the partial effects of the
variables of interest can be estimated and hypotheses on the directions and
magnitudes of the effects can be tested, econometrically. Third, our modeling also
provides insights that can assist language instructors in making and fine-tuning
teaching strategies.

Vinculin is one the most common proteins that have been studied commonly in recent years. Vinculin has anti-tumor effect and loss of vinculin causes development of many cancer types. Because of this Vinculin is a marker and it shoulde be evaluated for invitro and clinical studies. LC/MS based proteomics is the main tool to analyze hundreds of proteins in very short time because it offers high sensitivity and accuracy. Today nano LC is the min tool for LC/MS proteomics researches but UPLC/MS based systems have been developed and offered more robust and easy way for proteomics. In this study we used normal flow UPLC/Q-TOF method to analyze caco-2 colon cancer cell line. One of our targets for this study was to identify Vinculin as a cancer marker. We digested proteins from caco-2 cells and analyzed with UPLC/MS. Recorded MS/MS data was used with Maxquant bioinformatic system. We identified 5 unique peptides that belonged to Vinculin. We used 20 ppm mass tolerance for amino acid sequence matching with uniprot human database. We made three raplicate to observe identification reprocubility. Also We used label free quantification method and calculated vinculin intensity
