This paper investigates the effect of Gaussian window frequency response Side lobe Attenuation on the improvement of Speech quality in terms of six objective quality measures. In Speech Enhancement process, signal corrupted by noise is segmented into frames and each segment is Windowed using Gaussian window with variation in the side lobe attenuation parameter “α”. The Windowed Speech segments are applied to the Boll’s Spectral Subtraction Speech Enhancement algorithm and the Enhanced Speech signal is reconstructed in its time domain. The focus is to investigate the effect of Gaussian window frequency response side lobe level on the Boll’s Spectral Subtraction Speech enhancement. For various side lobe attenuations of the Gaussian window frequency response, speech quality objective measures have been computed. From this study, it is observed that the Side lobe Attenuation parameter “α” plays an important role on the Speech enhancement process in terms of six objective quality measures. The results are compared with the measures of Hamming window and an optimum side lobe attenuation parameter value for the Gaussian window is proposed for better speech quality.

We introduce and study contact normal generic submanifolds of a nearly hyperbolic cosymplectic manifold. We deal with the integrability conditions of the distributions of such manifolds. In addition to these, we study geometry of the leaves of distributions.

Disseminated cysticercosis is a rare complication characterized by extensive dissemination of larvae (Cysticercus cellulosae) of Taenia solium throughout the human body involving brain, subcutaneous tissue, skeletal muscles and other organs. The symptoms depend upon the parasite burden, its location, stage of cyst evolution and host immunity. We report a case of immunocompetent 47-year-old alcoholic male who presented with symptoms of chronic liver disease. Disseminated cysticercosis was an incidental finding. The emphasis is on the presence of calcified cysticerci in portal and splenic vein thrombus not yet described in literature and this makes our case worth mentioning.

The present research is intended to explore the mechanism which is causing, driving and accelerating the process of language change in Urdu. The particular focus is on the interplay of various factors which are resulting in the emergence of a more English-like Urdu language. The phenomenon of language change has been approached from a societal perspective and the link between social change and language change has been given particular attention by assuming that a change in society leads to a corresponding change in language and vice versa. Keeping in view the complex and multi-pronged nature of language-change, a mixed methodology has been employed. The findings show that changes in language are caused by different and numerous considerations and that these changes are natural, neutral and inevitable.

On Monday 20th of January 2003, the British Broadcasting Corporation (BBC) reported that a 74 years old Briton, who was terminally ill travelled to Zurich Switzerland and pain $60 to a group, Digital (dying with dignity) and he drank a cupful of barbiturates with a straw and died.His wife who assisted him was arrested on arrival in Britain. Why? Euthanasia and assisted suicide is illegal in Britain. The issue to be discussed here is euthanasia, its historical background, the scope of its otherwise, the religious aspect, the human rights dimension, problems and prospect of future.As Joubert said in the eighteenth century. It is better to debate a question without settling a question than to settle a question with debating beyond it. The goal is to debate the subject through probably not settled.The restriction against physicians aiding or assisting suicide. Its author and exact dates are unknown. The Hippocratic Oath is most famous for its command “to help or at least do no harm” and to respect all human life. It states “Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Since it arouses question about the morally of killing, the effectiveness of consent, the duties of the physicians, and equity in the distribution of resources the problem of euthanasia is one of the most acute problems in medical ethics.

In the discussion of such a topic as corruption which is a perennial subject of global concern one may start by defining some important terms in the topic. Corruption is an act done with an intent to give some advantage inconsistent with official duty and the right of others. The act of officials or fiduciary person who unlawfully or wrongfully uses his station or character to procure some benefit for himself or for another person, contrary to his duty and the rights of others

There is belief by the protagonist of the death penalty, that certain needs of the society which cannot be achieved by other methods are met by the execution of the criminal. That is the solution to certain crimes is the killing of the perpetrator of such crimes. The final solution to a deviant. The understanding philosophy is that whether the executions are carried out in public or shielded form behind the prison walls, death penalty is necessary, at least for the good of the society. Probably it is on the Benthamite, utilitarian or hedonistic, principle (felicific calculus) the promotion of the common will and the “the happiness of the greatest number.” This believe or argument has it major flaws.

when investors decide to buy shares or stocks in any company, there is the initial presumption that the company would in turn make profits which would then be delivered to them based on their investment. However, more often than not, there are cases where investors are faced with the situation whereby their investments could go down the drain due to bad corporate governance practices of the companyies in which the investments are made. Bad corporate governance practices and indeed control fraud have led to insider abuse whereby directors have failed to perform their fiduciary duties in proper management of the companies’ assets. These problems could be further compounded by the ignorant or complacent nature of shareholders with regards to their rights and responsibilities. In Nigeria, it can be said that shareholders are mainly faced with the problem of ignorance and in cases where they are actually aware of their rights; there is a passive nature of inexperience as to best approach possible in the circumstances. That notwithstanding, the recent banking crisis in Nigeria which is the subject matter of this paper has created a lot of awareness relating to shareholder activism in the country. These are seen in forms of Policies, Regulations and Scholarly Articles aimed at educating shareholders of their rights and responsibilities in the company. In view of this, it is the focus of this chapter to examine the extent to which shareholders can be said to have contributed to the banking crisis in Nigeria, taking into account the first five banks declared by the CBN as financially unstable. These are Oceanic Bank, Intercontinental bank, Union bank, Afri bank and Finbank. The paper will commence with an analysis of the concept of ownership and control, examining the agency problem associated with director-shareholder relationships. This will then be followed by an investigation of the legal position of shareholders rights and responsibilities in Nigeria, using the Compan

Introduction: Hypomagnesaemia has been reported to occur with increased frequency in patients with type 2 diabetes mellitus; it is frequently overlooked and undertreated. Materials and Methods: A total of 50 patients with type 2 Diabetes Mellitus were recruited from the institute’s medicine department. Fifty age and sex matched apparently healthy individuals with normal plasma glucose and with no symptoms suggestive of Diabetes mellitus were taken as controls. Both cases and controls were subjected to estimation of biochemical parameters. Objectives: The present study was conducted with an objective to evaluate the serum magnesium and fasting blood glucose in type 2 Diabetes mellitus cases and compare them with controls. The present study also attempts to evaluate the possible relationship between the modality of treatment and serum magnesium levels. Results: There is significant difference between levels of serum magnesium levels among diabetics and controls. The mean serum magnesium levels in cases and controls are 1.67 mg/dl and 2.03 mg/dl respectively (p<0.001). The mean serum magnesium levels in the OHA group, insulin group and the insulin+ OHA group were 2.02 mg/dl,1.59mg/dl and 1.25 mg/dl respectively. Conclusion: The serum magnesium levels were significantly lower in the insulin treated group compared to the OHA treated group. The serum magnesium levels were also significantly lower in insulin treated group compared to the OHA group.

In the present paper, a problem on reflection and transmission of elastic waves at a loosely bonded interface between an elastic solid and a viscoelastic porous solid saturated by viscous liquid is studied. The study is carried out with the assumption that the interface behaves like a dislocation which preserves the continuity of stress and allows a finite amount of slip. The appropriate potential functions for reflected and transmitted waves satisfy the required boundary conditions at the interface. The relations between amplitude ratios of different reflected and refracted waves are obtained for incidence of P and SV waves. The amplitude ratios of various reflected and refracted waves are computed for a particular model. The effects of loosely boundary and viscoelasticity are observed on these amplitude ratios.
