A single cylinder, 4-stroke spark ignition engine type Prodit; fueled with
supplementary Natural gas to liquefied petroleum gas (LPG) was used in this paper to
investigate the emitted CO pollutants. The effect of equivalence ratio, spark ignition
timing, engine speed, and the added NG volumetric ratio on CO emissions were
tested experimentally. The study outcomes revealed that CO levels depend mainly on
the equivalence ratio, as the maximum value of CO concentrations existed at the very
rich equivalence ratios and it low at lean side. Retarding spark timing increased the
CO concentrations by a significant percentage. The CO levels became higher at high
speeds and reduced at medium speeds. Increasing natural gas volumetric ratio in the
mixture caused a reduction in CO levels.

Abstract: In this paper, we investigate the bandgap energy, lattice constants, optical confinement factor, and physical properties of InGaN based quantum well lasers for 1.55 µm applications. Linear interpolation between the experimentally determined values of InN and GaN is used to calculate the lattice constants and the composition of the composite InGaN for the desired bandgap energy. Solving the Schrödinger equation in conjunction with k.p method and Luttinger-Kohn Hamiltonian matrix operator, the band profiles are calculated for the quantum well structure. First, the probability distribution is calculated, later which describes the electron density in the quantum well, and a value of 10-18 cm-3 is found from the calculations. In addition, the energies of conduction and valence bands are clearly demonstrated, and the corresponding heavy and light holes states are examined clearly. Determination of these parameters is of immense important for the microstructural fabrication, laser pumping power requirements, and practical applicability of the proposed laser structure.

The purpose of this study was to assess the general perception about TVET, and its contribution to socioeconomic status in preparatory school students of Amhara Regional State. To attain this objective descriptive survey
research method was employed. The subjects of the study were 226 preparatory school students of five selected districts.
Purposive sampling technique was used to select the target schools, while simple random sampling techniques were
employed to select the sample preparatory students. To gather the necessary data questionnaires and interview were used;
the gathered information was analyzed using both quantitative and qualitative method of data analysis. The liner
regression was used to determine if there are significant relationship between the perception and contribution to socio
economic status. The results of the study shows that there was significant relationship between perception and
contribution of socio economic status of TVET, they believed that TVET have strong contribution to society’s economic
status. However, the relative average mean score shows that there was positive perception from preparatory students and
respondent also strongly agreed to contribution of TVET to socio economic status. Evidence shows that positive
perceptions about TVET have a great contribution to society’s socio economic status. However, the provision of the
program should reach everywhere there was preparatory schools in the region and providing training which plays role in

The important role played by entrepreneur as an agent of economic transformation in every civilized society is
mostly visible in terms of employment and wealth generation, competitiveness and economic strength of a modern
nation. There is growing evidence to support the view that when people were exposed entrepreneurship trainings and
education programs, they tend to be more inclined towards entrepreneurial actions, and sometimes even become more
effective as entrepreneurs. The current economic realities in many developing economies have unavoidably forced policy
makers and the academics to place very high priority on developing entrepreneurial skills and knowledge through
education. This paper attempts to give a critical review of various literatures and related studies on entrepreneurial
competencies and shows how these competencies can be relevant and critical for lecturers teaching entrepreneurship
courses in higher learning institutions. Based on the reviewed related literatures in the study, it was discovered that
lecturers must possess some basic entrepreneurial competencies for effective teaching to their students as well as to
develop students‟ entrepreneurial skills and knowledge which are considered necessary for new venture management and
new venture creation. Three competencies that found to be very important for entrepreneurship lecturers are;
entrepreneurial knowledge, skills and attitudes. It recommended that this area of research should be broadened and
lecturers should develop their own competencies so that students aspiring in entrepreneurship can be aware of them
which can have greater chances in their entrepreneurial success.

economical behavior. The researchers tried to find out the role of gender and caste of the employee in his/her job
satisfaction. For this purpose primarily 575 primary school teachers were selected. Out of which 90 teachers (45 male
and 45 female) of General category, 90 teachers (45 male and 45 female) of Other Backward category and 90 teachers
(45 male and 45 female) of Scheduled caste category were selected. Thus finally 270 teachers were selected. Teachers‟
Job Satisfaction Scale (TJSS) was used to collect the data. The results of the two-way ANOVA showed a significant
interactional effect of caste category with gender on job satisfaction while there was a significant difference among the
caste category on job satisfaction. However, there was no significant difference between male and female teachers on job
satisfaction.

The aim of this paper is to analyze a pay scheme with three possible scenarios, all under the hypothetical
premise of the purchase of an appliance under three different terms of payment. In theory we know that the greater the
capitalization of an interest rate, the greater the increase of the burden of interest on the person who acquires the credit.
However, the calculations show that option 4, weekly payments, appears to be the option with the smallest interest
payment (5.93%) versus 5.99% and 6.20% for options 2 and 3, respectively. Finally, it is important to mention that the
import of each payment is what makes the difference: option 2 is $106.62, option 3 is $53.18 and option 4 is $24.53.
Option 1 is cash payment.

Good governance has in recent times appeared as the new intonation to address the failures of public systems,
especially in the arena of public health. Health is a state subject and the primary responsibility of providing health care is
with state governments. Majority of states' expenditure accounts of ail public expenditure on the health sector. Statelevel variations on expenditure on health over the years show a proportion to total government expenditure it shows a
declining trend after 1985-86. This article examined the allocations of health budget for the light of commitments made
in municipal governance of budget. The present study was carried out to assess the budget allocation and expenditure
pattern for health including private and public health. The findings revealed that the budget allocation for total health care
was less, compared to that of maternity home and child care budgets. The study focused on trends in BBMP spending on
Health Sector. The results conveyed that the BBMP spending on health sector as per state Real GDP for BBMP
Budgetary allocation was low compared to real allocation. These figures indicate the status of ignorance of urban public
health sector. The study suggested that the prime importance of health care both at micro and macro levels needs to be
attentive at budget allocation and at management strategic decisions to regulate the health care policy to achieve this
sectors as one of the millennium development goals which is most vital for growing urban population through both
public and private partnership interventions.

Oral cancer is a public health problem. Despite all the efforts and improvements in the field of oncology, the
mortality rate had not significantly declined in the course of recent years. This may be due to the fact that diagnosis of
oral cancer is frequently delayed. The main goal of this study is to analyze the factors responsible of this delay. We
analyzed the clinical history of 76 patients with oral cancer diagnosed in our center from 2013 to 2016. We divided the
diagnostic delay into 3 major groups: delay attributable to patient, delay attributable to public health system and delay
attributable to professionals. According with our results, the major delay is attributable to patient. However, we find that
the waiting time to get an appointment with Maxillofacial Unit is too long for patient referred by family doctors and
dentists (α <0,01). Moreover, we could observe that other hospital professionals such as emergency physicians and ENT
specialists take less time to suspect oral cancer than family doctors or dentists (α <0,01). However, dentists suspected
oral cancer earlier than family doctors (α <0,01).the major diagnostic delay is due to patient and this could depends on
several variables. However, the waiting time to obtain a specialist consultation after the request of family doctors or
dentists is too long. The creation of special derivation protocols is essential in cases of suspicious lesions.
