A lot of controversy continues regarding the development of human penile urethra.Posterior urethral valves are congenital disorder and can only seen in male infants. It caused by failure of regression of the mesonephric duct. Most of cases PUV’s a sporadic and only occur in males, evidence suggests that they can be found in siblings or twins in a family. If PUV’s are not diagnosed and treated early they can cause damage in the ureters, urethra, bladder and kidney, constraints lung developments cause of low quantity of amniotic fluid. PUV’s are commonly diagnosed prior to birth or at birth when a male infant is evaluated for antennal hydronephrosis.

Pre-ureteric vena cava is a rare congenital disorder, usually presenting clinically with hydronephrosis and an “S or fishhook” deformity of the ureter at the lumbar vertebrae three and four. Unusual presentations do occur and can lead to misdiagnoses. Though it is a congenital disorder, patients do not normally present with symptoms until the 30 years of life with various complains, results due to back pressure changes lead to hydronephrosis (water in the kidney).

There has been a varied advancement in the English language teaching materials for second language learners. Even though materials are in abundance, poetry seems to lack its appropriate usage in the process of second language teaching. Traditionally poetry may have lost its function as an attractive tool to impart novelty in teaching a language; the present study focuses to teach the four basic language skills and the linguistic role in learning English Language through poetry. Teaching second language through poetry is effectual since it made the learners to stir out their own insightful thinking and to stimulate their creativity. The interpretative ability of the learners had a gradual increase when a few lines were given to interpret. Thus the paper suggests that poetry is very beneficial for the teachers of English in second language learning classrooms.

The present research paper examines the factors which a company must consider while implementing Green Supply Chain Management (GSCM) practices. Three companies from Indian “Food and Beverage” (F&B) sector are examined in their approach to be more sustainable. The research method employed is comparative case study analysis. Semi-structured interviews are held with two relevant managers from each company. Top-management support is crucial for effectively working GSCM practices. Employee involvement is recognized as crucial element of GSCM. An environmental friendly company culture is beneficial and should be derived from the companies’ environmental vision and mission. Collaborations with suppliers are perceived to be productive and essential to develop innovative products.

This study examines to analyze and compare errors of concord students often conflict when speaking or writing essay. The comparison was made after 4 month of first term, examination in the case of the SS1 and SS3 classes respectively. The respondents were made up of Senior Secondary one (SS1) and Senior Secondary three (SS3) classes of Ogbemudein Mixed Senior Secondary School, Agbor, Delta State, Nigeria. Both respondents were asked to write an essay twice with four months interval on the same topic. In each writing sessions, there were 60 essays written by respondents, giving a grand total of 120 essays being analyzed. The results showed an increase in errors resulting to 3.40% among students in the senior secondary one (SS1) but with drastic reduction of 10.48% among the Senior Secondary three (SS3) which of course performed below expectation.

Super-resolution is the process of creating an high resolution image from a low resolution input sequence. To overcome the difficulties of good image registration, several methods have been proposed exploiting the non-neighbourhood intuition, i.e. any data-point can contribute to the ?nal result if it is relevant. These algorithms however limit in practice the search region for relevant points in order to lower the corresponding computational cost. Furthermore, they de?ne the non-neighbourhood relations in the high resolution space, where the true images are unknown. In this work, we introduce the use of phantom hashing to efficiently compute fully non-neighbourhood neighbours. We also restate the super-resolution functional using ?xed weights in the low resolution space, allowing us to use resolution schemes that avoid many artifacts.

Harvesting solar energy has been the keen focus of study among researchers all over the globe. In the current scenario of fast depleting non-renewable resources, efforts have to be made for maximum utilization of available solar radiations. The present review studies NEILS as one of the front runner as suitable HTF for solar collectors due to their impeccable thermal properties and the various possible reasons for enhancement in heat transfer properties of NEILS.

Supply of power for an implantable medical device through a thermoelectric generator shows potential way for a biological system. The direct utilization of the temperature difference existing whole biological body is the unique feature. This paper attempts to review the energy generation of an implanted thermoelectric generator for various physiological or environmental thermal surroundings. Also several technical approaches included to enhance the energy generation from an implanted thermoelectric generator, to shows its long-term potential energy supplier for such medical practices.

In the modern commercial era, companies and their managers are subjected to well publicized pressure to play an increasingly active role in society – so called “Corporate social responsibility”. It has been argued that an element in this development is simply enlightened self-interest in that social responsibility enhances corporate image and financial performance. To date the evidence to support this thesis derives from North America. Outside this continent evidence for any relationship is sparse. This study will initially attempt to define. The concept of corporate social responsibility and to examine its guiding principles. Subsequently, the available empirical research into the link between corporate social responsibility and economic performance will be evaluated this study examines different impacts of positive and negative CSR activities on financial performance of hotel, restaurant and airline companies, theoretically based on positivity and negativity effects. Findings suggest mixed results across different industries and will contribute to companies’ appropriate strategic decision-making for CSR activities by providing more precise information regarding the impacts of each directional CSR activity on financial performance.

The electronic absorption spectra of 3,5-diamino-1,2,4-triazole was recorded in the region of 190-450 nm. Quantum chemical calculations of energies, geometrical structures and electronic absorption spectra of 3,5-diamino-1,2,4-triazole were carried out by ab initio HF/6-31+G*, DFT (B3LYP/6-31+G*) and TD-DFT /B3LYP/6-31+G* level of theory with complete relaxation in the potential energy surface. The Mulliken charge analysis indicates that the nitrogen atoms of the triazole ring and the amino group attached to the ring are the main reactive centers of 3,5-diamino-1,2,4-triazole. The calculated HOMO-LUMO energies show that the molecule has low energy gap which implies low kinetic stability and high chemical reactivity. The study is extended to the analysis of dipole moment, EHOMO, ELUMO both in the gas phase and in the presence of solvent for comparison. Thermodynamic properties were also calculated and discussed. The calculated values of absorption wavelengths are compared with the experimental data for this molecule as a means of validation of the theoretical model used. The predicted results are in excellent agreement with the experimental ones.
