Heavy metal copper is the third most widely used metal in industries next to aluminium and iron. It finds its use in various industries like electroplating industries, battery manufacture, smelting, ship building, electrical transmission, construction of transportation vehicles, construction industry etc. The permissible limit of copper in water for human consumption as per World Health Organisation (WHO) is 0.05 to 1 mg/lit. Beyond this limit, the presence of Cu (II) ions is carcinogenic and toxic to human health. Therefore, there is a need to remove copper from waste effluents before allowing it to enter into any water body. The present study deals with the removal of copper by adsorption on neem leaves (Azadirachta indica) in batch experiment, by low-cost and high-capacity removal of Cu(II) ions from wastewaters. The influence of contact time, adsorbent dosage, effect of pH of solution and temperature effect were studied. Adsorption mechanism is found to follow the ‘Freundlich’ adsorption isotherm, indicating a multi layer adsorption process. Percentage removal of Cu (II) ions is found to be 88.516% at pH 3 for 0.1gm of Neem Leaf powder (NLP) dosage. The results obtained from this study shows that Neem leaf powder is an effective and economical adsorbent for copper removal from industrial wastewater.

In this work Doppler barding in measurements used to allow free Doppler absorption. The measurable velocity (m.s-1) was in the range of -5.2x107 to5.2x107. The maximum measurable velocity (m.s-1) was found to be limited by the signal-to-noise ratio. The intensity spectrum broadened linearly when velocity (m.s-1). At the same time, the spectral amplitude decreased and eventually approached the noise level. Increasing the laser power or improving the transducer sensitivity can extend the maximum. In contrast, the minimum measurable velocity (m.s-1) increased. Immediate, which represents the velocity sensitivity of the system, was limited by the frequency resolution of the system(-1.5x1014 Hz). Increasing the number of piezoelectric transducer cell (PZT) points can improve the minimum.

To evaluate the natural rejection capacity of six plantain cultivars collected in five territories in the province of Maniema, in the Democratic Republic of Congo. The trial was conducted using an experimental system of subdivided plots and observations were made on the number of naturally formed shoots, the diameter, the height of the pseudo-trunk and the leaf area of the plant. The correlation between the number of shoots and these three parameters was calculated. The results obtained were as follows: 8.17 ± 2.72 shoots were produced in the control, 8.50 ± 2.62 in the sawdust and 8.26 ± 2.68 in the decomposed rice husks. The averages per cultivar for all fertilisers and per cultivar were 9.37 ± 0.11 for C6 (Otangala); followed by 8.76 ± 0.65 for C4 ((Mbonjilo) ; 8.43 ± 0.12 for C5 (Kambelekete) ; 8.03 ± 0.48 for C1 (Kyankola)1 ; 7.89 ± 0.19 for C3 (Mbudi 2) and 7.37 ± 0.48 for C2 (Mbudi 1). It was found that these numbers of rejections do not differ statistically between fertilisers and between cultivars. The correlation coefficients are therefore generally low or mogged, negative or positive. The data are heterogeneous within fertilisers and homogeneous within each cultivar.

This paper expounds processes of read understood and information transferred from epistemology and ontology according to customers’ requirements of knowledge service. It points out that method frames of content contrast were to access knowledge points via study on definition of knowledge and forms of semantic description. Some literatures would be contrasted with couple to couple by computer technology in order to raise read understanding efficiency.

Background: The hypothalamic/pituitary/gonadal (HPG)axis is central to the mammalian reproductive system. Pulsatile release of GnRH from neurons in the hypothalamus stimulates the secretion of LH and FSH from gonadotropes in the anterior pituitary. It has long been recognized that reproductive function is closely associated with energy balance, and metabolic dysregulation is linked with reproductive abnormalities (Lu et al.,2008). Compare the differences in levels of adiponectin, FSH, LH, testosterone and estradiol between the diabetic patients and control group and in diabetic patients according to the durations of disease for both males and females groups .Also study the relationship between adiponectin and hormones for both gender and for both diabetic groups and control also in diabetic patients according to the durations of disease. The statistical analysis of this study showed that patients with Type 2 diabetes of both males and females had significantly lower in adiponectin levels than control group (P<0.05),but this level of adiponectin significantly higher in females than males for both diabetic groups and control (p<0.05) ,while the levels of FSH and LH had significantly higher in diabetes group than control (p<0.05) ,also significantly higher in females than males for both diabetic groups and control (P< 0.05). The result of hormonal analysis show there were no significant differences in estradiol and testosterone between diabetic groups and control (p > 0.05). According to the durations of disease, the results show significant elevation in adiponectin level in third duration of disease for both males and females groups as compared with first and second duration (P <0.004), while the levels of FSH, LH ,estradiol and testosterone show no significant differences among duration(P>0.05).

The extent of success by organization can be considered in their effectiveness and this would not achieve unless a proper structure. Informing organizational effectiveness and measuring its relationship with organizational structure as an affecting factor on organizational effectiveness, one can identify an ideal extent of structural elements relevant to organizational internal and external conditions. By revising and modifying such elements and by making structure effectiveness, one can accelerate moving toward aims and can increase organizational effectiveness. Present study evaluates the relationship between organizational structure and effectiveness in Kerman province Red Crescent. Research method is survey-type and questionnaire is the tool to gather data. Its population consists of managers and staff of Kerman province Red Crescent. The statistical sample included 189 managers and employees of the organizational and sampling method is an objective one. The studied variables include organizational effectiveness, organizational structure, concentration, formalization and complexity. The findings show that there is a relationship between organizational effectiveness and organizational structure. Such relations are as follow: the relationship between effectiveness and complexity is directly significant, it is adverse significant between effectiveness and concentration and it is directly significant between effectiveness and formalization.

The term alienation which Raymond Williams calls it as one of the most difficult vocabulary words, and as one of the main concepts in sociology, psychology and social psychology have been introduced, Is widely used in social science to explain the forms and types of actions and reactions to events, facts, psychological and social pressures and is hardly associated with people’s life. Regarding to the importance of the topic in this research by using field method, techniques and survey questionnaire sought answers to this question” what are the social factors affecting student alienation?” The study sample is Guilan-e-Gharb PNU students which about 382 persons of them have been surveyed as the sample of the study. In order to answer the main question of this study, the relationship between variables such as social trust, social participation, social cohesion, devoutness and economic-social base as independent variables and its relationship with the students' alienation as the dependent variable was analyzed. The results indicate that among all the independent variables with the dependent variable, there was a direct and significant relationship. The relationship of these variables is moderate.

The metal complexes of Co²⁺ and Ni²⁺ 1,2,3-triazole mixed ligand have been synthesized. The synthesized complexes in different ratios have been characterized by element chemical analysis, molar conductance and Uv-visible and FTIR spectroscopic studies. IR spectra data suggests the involvement of sulphur and nitrogen in coordination to the central metal ions. On the basis of spectral studies and elemental analysis, a tetrahedral geometry was assigned for the nickel complexes while dimerization was suspected for cobalt(II) complexes. The free ligand and metal complexes were tested in vitro against a number of microorganisms (fungi and bacteria) in order to assess their microbial properties. They are found to be proactive against fungi and bacteria upon the metal complexes, nickel complexes performed better than the cobalt complees.

This study investigated the tactics used to curtail women participation in national elective leadership positions among the Abagusii of Western Kenya. Data for this study was collected from 15 Gusii women who were purposively selected because of their participation in the 2013 and 2017 national elections as contestants. The study found that women were unable to win any national elective seats which they competed with men. Their failure was attributed to the tactics male contestants used against them. These tactics were mostly based on moralistic codes of gender and sexuality. This study argues that policies that aim at enhancing women participation in elective leadership positions must first address the social construction of women sexuality in each community.

Many small businesses in the United States, including barber salons face challenges in succeeding during the initial years of business formation and establishment. The factors responsible for the low survival rate of salons may include factors such as the limited training and education levels mandated by state certification requirements. The purpose of this multiple case study was to identify business strategies that successful barber salon owners use to overcome the business management and staffing challenges associated with a small pool of skilled barbers and the high turnover in a low wage profession. The theory of transformational leadership served as the foundation of the conceptual framework. The data collection included interviews of 3 successful barber salon owners who met the study participation eligibility criteria of licensed, registered, operating a salon business in the Indiana region for more than 5 years, and over the minimum age of 25 years. The principal themes emerging from the interview data analysis were salon leadership and managerial strategies. The data analysis also involved the triangulation of the primary research data against secondary data from the Small Business Administration and barber industry reports. The expertise and knowledge shared by the interviewees could serve the quest of barber salon businesses in the Indiana region to overcome the profitability and financial sustainability challenges of this industry. The study findings may potentially contribute to positive social change by improving the economic standing and welfare of barber salon owners and professionals in the community.
