In quantum mechanics a localized attractive potential typically supports a (possibly infinite) set of bound states, characterized by a discrete spectrum of allowed energies, together with a continuum of scattering states, characterized (in one dimension) by energy-dependent phase shift. The Morse potential named after physicist Philip M.Morse, is a convenient model for the potential energy of a diatomic molecule. It is a better approximation for the vibrational structure of the molecule than the quantum harmonic oscillator because it explicitly includes the effects of bond breaking such as the existence of unbound states. It also accounts for the anharmonicity of real bonds and the non-zero transition probability for overtone and combination bands. The Morse potential can also be used to model other interactions such as the interaction between an atom and a surface. We here make the case that the trigonometric Rosen-Morse potential is exactly soluble in terms of a family of real orthogonal polynomials and present the solutions. and analytical solutions of the Klein-Gordon equation for the Rosen-Morse potential with equal scalar and vector potentials are studied in this paper.

Development is a key factor in every given society. Although, the concept of development and its understanding differs from society to society. That is, each society has ways of developing itself passing through the necessary developmental stages. The success of these stages is a function of many key factors such as the environment, interaction with other societies within and outside, leadership and its style, management, culture, individual and collective goal(s) of the people and of the community and the people themselves. The MDGs is meant for Africa as a continent with a bench mark of 2015, what is the situation of realization of these goals in spite of the financial resources committed to this course ? What are measures put in place by Nigeria as a country or to what extent have we gone in realizing these MDGs? Hence this article to investigate the issues and problems of MDGs in Nigeria. The secondary method of data collection was thoroughly explored in this article. The article noticed that Nigeria as the GIANT of Africa might not attain the MDGs even if smaller nations (Ghana, Cameroon and Botswana etc) in Africa does.

Financial markets require an accurate estimate of asset volatility for various purposes such as risk management, decision-making and portfolio selection. Moreover, for risk management, volatility estimation is critical in Value-at-Risk (VaR) calculation models. However, there is still no consensus on a model that performs best in estimating volatility. This study proposes comparing volatility measures based on high-frequency data, such as RV and RRV, with heteroskedastic volatility models that use squared daily returns and daily closing prices. Four GARCH type models were implemented to estimate heteroskedastic volatility for the two most actively traded shares on the Brazilian stock exchange, using skewed generalized t (SGT) distribution and allowing flexibility for modeling the empirical distribution of these asymmetric financial data. Performed tests indicated no differential between the GARCH models and the high-frequency volatility measures used to estimate the VaR, indicating that both measures could be utilized for risk management purposes.

Two dimensional motion of an incompressible second grade fluid in a porous medium with Hall effects has been considered. Exact solutions are obtained via inverse method when vorticity distribution is proportional to stream function ψ, perturbed by a quadratic term.

This research was aimed to create valid, practical, and efective syntax of production based learning model in the context of Vocational Education and Training (VET). Production based learning is an alternative learning model of VET which is relevant to the needs of learners in developing their knowledge, attitude, and skills in learning process. Reserach methodology used was Research and Development by conducting expert validity test with Focus Group Discussion (FGD) and limited test towards production learning based model. The results of this reasearch were formed in syntax of production based learning model which consisted of; (1) Analysis of curriculum and learners characteristics; (2) Identification and product analysis; (3) Creating important questions about product; (4) Questions mapping; (5) analysis of equipment and materials needed of the product which was going to be made; (6) making schedule of implementation of making product; (7) process of making product; (8) evaluated regularly; and (9) creating bussiness plan. Finally, by applying production based learning model in Vocational Education and Training (VET) can help learners preparing themselves to enter work, as well as developing their critical thinking and having good moral attitude.

a) Aim To discuss the condition of a child patient with abdominal pain related to autoamputated appendix. b) Case Report A male patient at 12 has admitted to our clinic with abdominal pain and vomiting complaints lasting for two days. His white blood cell (WBC) count was 9,100 and C-reactive protein (CRP) level was 27,89. Although direct radiographs have reflected normal structure, there was a diffuse thickening on ileum and there was a peripheral fluid collection surrounding the caecal walls. The p atient w as h ospitalized. H is a bdominal p ain h as temporarily relieved but, he has undergone surgical intervention as his abdominal pain has exacerbatively recurred a t t he e nd o f d ay o ne. D uring intraoperative exploration, we have observed that the appendix was totally seperated from caecum and its mesenteric perfusion was partially deteriorated (Fig. 1). Appendectomy operation was performed without caecal s uturation ( Fig. 2 ) a nd o ur p atient w as discharged from hospital two days after the operation with total remission.

Bangladesh receives about $56.5 billion foreign aid during 1971-2012 periods. This paper analyzes 33 years data for 1980-2012 periods to show the effects of foreign aid on the economic growth of Bangladesh. This study estimates eight models including three for last three decades (1980-1990, 1991-2001, 2002-2012), four for the four different government periods, namely, Military government period (1982-1990), BNP (Bangladesh Nationalist Party) government (1991-1995, 2002- 2006) , BAL (Bangladesh Awami League) government (1996- 2001, 2009-2012) and the Whole Democratic government period (1991-2012) and one for entire period (1980-2012). This research finds that, foreign aid has positive effect on the economic growth of Bangladesh and it is statistically significant in two models. The contribution of aid to GDP is falling overtime. This paper also reveals that the aid generates decreasing returns because of capacity constraint of Bangladeshi institutions to utilize foreign aid effectively. This finding is consistent with previous findings of different researches.

Usual test of testing unit root such as Dickey-Fuller (DF), Augmented Dickey-Fuller (ADF), Phillips Perron etc ignores sign and boundary of parameters. In this paper, we demonstrated the ignorance of sign and boundary of parameters and consequences of this ignorance in estimation and testing by Monte Carlo Simulation. Our main objective is to develop a method to capture the non-stationarity keeping in mind the boundary and sign problem and to develop the restricted ADF test based on ESS using the constraint estimate of parameters. We compare the power properties of the usual ADF test and ADF test with restricted error sum of squares using the constraint estimate of parameters by Monte Carlo Simulation and we find that the proposed ADF test gives better result than the usual ADF test in terms of power properties.

Unmet need is defined as not using contraceptives despite expressed demand for limiting or spacing a child exists to varying degrees in virtually every developing country for various reasons. There is limited knowledge about the extent and associated factors of unmet need for family planning in the study area. Therefore this community based cross-sectional study was conducted. The overall unmet need for family planning was 41.5%. It was relatively lower among currently married women that 34.4% of currently married women had unmet need for family planning. More than 50% of the demand for family planning was not met. Factors like ethnicity, age of the participant, participant’s education, husband’s occupation, having discussion about family planning with partner in the last 6 months and gravidity were independent predictors of unmet need for family planning among currently married women. Efforts to be exerted were recommended in order to reduce this high rate of unmet need by focusing on those kebeles which Wolayta and Zeyse tribes live, older age, illiterates and those with high gravidity.
