The main objective of the study is to empirically examine the impact of working capital management on Pakistani manufacturing corporate profitability. The study uses a sample of randomly selected companies from three manufacturing sectors i.e. consumer goods, chemical and construction & material for the period of five years ranging from 2006 to 2010. The correlation and panel data regression analysis were used to analyze the impact of working capital management on the corporate profitability. The results indicate that, the average collection period of account receivables, inventory conversion period and cash conversion cycle have strong negative relationship with corporate profitability while the current ratio has positive relationship with operating profit. The study also finds that the firm size and current assets to total assets ratio has significant positive relationship with corporate profitability. Findings indicate that finance manager can improve the firm profitability by focusing on each component of working capital. More specifically they can improve the firm profitability by reducing account receivable period, inventory conversion period and cash conversion cycle. We also find that average collection period is the most crucial component of working capital. So the manger can add value to the firm by fastening the account receivable conversion period.

The vibrational spectroscopy of 2-Hydroxy-6-methyl-5-Nitropyridine (HMNP) by means of quantum chemical calculation has been studied. The FT-Raman and FT-IR spectra of HMNP have been recorded in the region 3500-50cm-1 and 4000-400cm-1 respectively. The fundamental vibrational frequencies and intensity of vibrational bands have been evaluated using density functional theory (DFT) with standard B3LYP/6-311+G (d,p) basis set combinations for optimized geometries. The observed FT-IR and FT-Raman vibrational frequencies have been anlaysed and compared with theoretically predicted vibrational frequencies. The assignments of bands to various normal modes of molecule have also been carried out. The electric dipole moment (?) and the first hyper polarazibility (?) values of the investigated molecule have been computed using DFT calculations. The calculated HOMO and LUMO energies show that charge transfer occur with in the molecule.

Bacterial communities exist everywhere in the universe so in the caves. The ever increasing human activities inside any cave, in the form of ecotourism exert a major impact on its native microbial communities, which often stops its growth and pollutes the whole ecosystem. The situation is often found to be responsible for producing some human pathogenic bacteria inside it, which might pose a threat of infection to the other tourist. Kotumsar cave is a well known tourist pulling limestone cave of central India. In the present study the soil bacterial communities earlier isolated and characterized from different microhabitats of Kotumsar cave have been further confirmed by molecular identifications by applying 16S rDNA analysis and serotyping. All bacterial strains were also assayed for antibiotic resistance. Among the tested strains, support the PIB-win results and also shows the maximum resistance (about 69.23%) to Vancomycin and Polymyxin B.

A single factor that enables the teachers to discharge their responsibilities is commitment. This commitment is towards their profession, excellence, students, society and basic human values. A teacher is supposed to possess various quality attributes like updating of knowledge, teaching skills, providing course material from various sources to the students, outside class-room assistance to the students, use of modern teaching aids, communicating the teaching plans and revising and upgrading the syllabus. The degree of importance in various quality attributes of faculty members is examined by the students. The sample has been taken from 44 institutions of higher education in Haryana. 10 students from each institution were included in the sample. These 44 institutions include 19 urban aided institutions (13 co-ed. And 6 women colleges), 8 urban government institutions (5 co-ed. and 3 women colleges), 11 rural aided institutions (3 co-ed. and 8 women colleges) and 6 rural government institutions (3 co-ed. and 3 women colleges).

Persian shallot grows as a wild plant in some mountains of Iran. Persian shallot, a bulb producing plant from Alliaceae, is a wildly growing plant collected for its bulbs. Bulbs of Persian shallot, called “Mooseer” in Farsi, are oval, white skinned, usually of one and rarely of two main bulbs and are completely different from common shallot (Allium ascalonicum). In this study, various physical properties of Persian shallot were determined at a moisture content of 68.62% w.b. The equatorial diameters, polar diameters, shape index, volume and density were 36.647 ±3.30 mm, 33.242 ± 3.47 mm, 1.0898 ± 0.07, 3.5106 ± 0.961 cm3 and 5211.292 ± 1108.463 Kg.m-3, respectively. The static coefficient of friction was obtained on the plywood surface followed by the glass and the galvanized iron sheet surfaces. The shear strength increased with an increase in loading rate. Linear model for describing the mass of Persian shallot, by applying dimensional characteristics and volume was investigated. The results showed that mass modeling of Persian shallot based on oblate spheroid shaped volume (Vosp) and geometric mean diameter (Dgm) are the most appropriate models, respectively.

A design of experiment is a plan to collect measurement or observation according to a pre arrange plan in such a way as to provide the basic for valid inference. This work was carried out to examine the research station effect on the yield of Cowpea varieties. The station are four locations in Nigeria (Kaduna, Shika, Mokwa and Kano). Eight different varieties of Cowpea were considered (Tg 1910-8F, Tg 1844 – 1E, Tg1019 – 2E, Tg1904 – 6F, Tg1910 – 2F, Tg1448 – 2E, Tg1908 – 1F, and Tg1740 – 2F). The data are secondary data, collected from International Institute of Tropical Agriculture (IITA) Ibadan, Oyo State. The result showed that research locations has no significant effect on the yields of cowpea varieties. The use of Randomized Complete Block Design (RCBD) design in Kaduna station, Shika station, Mokwa station and Kano station had 27.2%, 109.9%, 63.04% and 53.7% gain in experimental precision respectively.

An experimental study has been carried out on axially loaded short and slender high strength concrete columns confined with glass fiber-reinforced polymer (GFRP) sheets. A total of 10 specimens were loaded to failure in axial. The column specimens are square in shape with 150 mm length,150 mm width and 1000 mm height. Concrete compressive strength was 58 MPa. All columns were reinforced with steel and wrapped with different layers of GFRP. Results of testing was increasing the compressive strength of concrete column with GFRP wrapping, the columns wrapping with glass FRP is most effective in control column. Four layers of FRP wrapping of column was gave the highest result of compressive strength test. A modified analytical model was presented to predict the strength of FRP-confined square column.

Biotechnology is one of the new and strategic technologies which have been regarded as a suitable and powerful tool for access to sustainable development. For this reason, some countries have made long-term investments and planning for utilization of its potential. In Iran, many efforts have been made to progress biotechnology and pharmaceutical biotechnological projects have been transferred to the country. But requirement of a suitable technology transfer to the country is transfer of this technology based on a compiled and conscious plan. In this article, three objectives have been considered: The first objective is views of the experts about essential questions including barriers to technology transfer in pharmaceutical biotechnology, methods of technology transfer and the used models for transfer. The second objective is study of technology transfer process in projects transferred to the country. In this regard, different phases of technology transfer were specified and the specialists were asked to answer this question to specify weak and strong points in technology transfer. The third objective is study of factors effective on technology transfer in pharmaceutical biotechnology. In this regard, important elements in technology transfer process which can cause to progress this industry in the country were specified by coordination with specialists and experts and such indices were studied with use of DEMATEL technique to specify what elements are effective on technology transfer process and which elements are affected in technology transfer process which can play important role in decision of the authorities.

Single crystals of L-arginine monohydrate of reasonable size and excellent quality were grown by the solution growth method. The powder XRD of the samples suggested no significant change in the unit cell dimensions and the presence of any extra phase. The structural analysis can be useful in the clarification of the role of hydrogen bonds in crystals exhibiting non-linear optical properties. The dielectric studies shows the the governance of various polarization mechanisms. The mechanical response of the crystal has been studied using Vickers microhardness technique.

One of the important models in tunnel design and underground structures are determining the stresses and stress concentrations around them. The method of analysis is usually based the theory of elasticity. Therefore; it has the advantages of accuracy and uniqueness respect to the numerical models. The stress conditions in subsurface or underground domains are usually in the form of both normal and shear stresses. Those are because of the geological features such as bedding, jointing, folding and nonuniformity of petrology. Therefore; the directions of principal stresses are not parallel to the original Cartesian coordinates and they make specific angles to the x and y-axis. The analysis is two-dimensional for circular tunnel and it is applied for plane stress and plane strain conditions. The analysis can be applied for the case of supporting pressure pi. The radial and tangential deformations could also be determined at the roof and walls of tunnel.
