Abstract: In lower middle-income countries like Ghana, it is common to find low contraceptive use among adolescents with corresponding high pregnancy outcomes. Evidence points to the fact that the use of contraceptives prevents maternal, neonatal and infant deaths, but in most lower middle-income countries, socio-cultural practices inhibit adolescents’ use. Ensuring the uptake of family planning among adolescents is deemed a necessary means of reducing maternal, neonatal and infant mor-tality. This manuscript seeks to provide contextually relevant approaches to satisfying family planning needs of adolescents in a population lacking it. We employed a qualitative study design from an interpretive paradigm with phenomenology as the methodology to understand societal attitudes towards family planning delivery to adolescents, so as to arrive at contextually appro-priate ways of providing family planning to this needy group. Focused group discussions and in-depth interviews techniques were used in data collection among adolescents, relevant commu-nity opinion leaders and family planning & health services providers. Themes that emerged from data analysis with respect to “perspectives on family planning care delivery to adolescents” and “best ways in addressing adolescents’ family planning needs” are presented, followed by discussion of the issues emerging. A significant and encouraging finding of the study was that opinion leaders and healthcare providers viewed family planning as a means of protecting adolescents against pregnancies and their complications. A key recommendation is for policy makers and political leaders to enact legislations that enable adolescents to have friendly family planning service delivery in all places and at all times.

Abstract: The study employs a mixed method design, using cross-sectional survey and focus group discussions to further understand issues related to awareness and attitudes towards microbicide development, acceptability and perceived partner attitudes among pregnant women attending antenatal clinic in two health facilities in the Kintampo North municipality of Ghana. We used logistic regression to identify possible predictors of microbicide acceptability among the women surveyed.Although only 2% of the 504 women were aware of the development of microbicides, 95% were willing to use one when it became available. The cost of a microbicide that will be considered affordable to 50% of women was US$0.75. Although there were concerns about possible wetting effect, gel or creams were the most preferred (68% of women) formulation. Although 71% thought their partners will find microbicide acceptable, apprehensions about the feasibility of and consequences of failed discreet use were evident. 49% of women were concerned about possible negative effect of microbicide on sexual pleasure. Perceived partner acceptability (O.R. =17.7; 95%C.I. 5.03-62.5) and possibility of discreet use (O.R. =8.9 95%C.I. 2.63-30.13) were the important predictors of microbicide acceptability.Achieving microbicide acceptability among male partners should be made a part of the promotive interventions for ensuring effective use among women in rural Ghana.According to the 2010 UNAIDS report on the global AIDS epidemic, 33.3 million people live with HIV and 1.8 million deaths due to AIDS occurred in 2009. The total number of new infections in 2009 was 2.6 million. Sub-Saharan Africa remains the hardest hit by the HIV/AIDS pandemic and access to HIV prevention, treatment, care and support in this part of the world remains a major priority in global health [1,2].Heterosexual transmission accounts for more than 80% of all new HIV infections in sub-Saharan Africa [3].

Abstract: Family planning is known to prevent maternal deaths, but some social norms, limited supplies and inconsistent use makes this difficult to achieve in most low- and middle-income countries. In spite of the high fertility levels in most sub-Saharan African countries and the potential economic benefits of family planning, its patronage remains very low in the sub-region. This study was with the objective of identifying the levels of awareness, utilization, access to and perceptions about family planning and contraception. A cross-sectional study design was used for the study, with data collected from multiple sources using both quantitative and qualitative approaches. Relevant findings included a marked disconnect between family planning/contraceptive knowledge and use. The pills and injectables were the most frequently used, but females in the study population poorly patronised emergency contraception. Supplies of most family planning methods were found to be health facility based, requiring clients to have to necessarily go there for services. Some respondents harboured perceptions that family planning was the responsibility of females alone and that it fuelled promiscuity among female users. Recommendations made include ensuring that health facilities had adequate staff and expertise to provide facility-based family planning services and also to disabuse the minds of community members of the negative perceptions towards family planning.

Abstract: The manuscript presents findings of a descriptive analysis of data from a cross-sectional study of adolescents aimed at identifying their family planning needs and the best approaches to addressing them in the Kintampo Districts of Ghana. Data for the paper were from the family planning module of a sexual and reproductive health survey carried out by the Kintampo Health and Demographic Surveillance System in 2011. Adolescents in this study recorded high marital (1.6% females and 0.4% males) and pregnancy rates (11.5% females and 1.5% males). Their knowledge of contraceptive methods was high (87.7% females and 82% males), but utilization was low (17.9% females and 6% males). Most study participants viewed family planning as important to their health and wellbeing (59.6% females and 58.6% males). A minority of adolescents were of the perception that contraceptive use was solely the responsibility of women (41.1% females and 32.4% males); and that the use of contraceptives could lead to promiscuity among women (43.8% females and 42.5% males). Those adolescents who previously had unwanted pregnancies would have accepted some help in preventing it (33.1% females and 9.1% males). Recommendations made by respondents included creating a friendly atmosphere by care providers for family planning services delivery to adolescents. Other suggestions were ensuring that family planning services are available and accessible to adolescents, and educating adolescents on the diverse methods available.

Abstract: This study investigated the influence of both shaking duration and number of trees per bale on postharvest needle characteristics such as percentage needle loss, needle retention duration and explored the physiological roles of endogenous ethylene and volatile terpene compounds (VTCs). To accomplish these objectives, 25 six-year-old trees were detached and exposed to a range of shaking durations (0 to 60 sec.), and 30 six-year-old detached trees were exposed to baling treatments from 0 to 5 trees. Response variables measured were percent needle loss, needle retention duration, average water use, ethylene and volatile terpene compound evolution. Trees shaken for 60 seconds lost 16% less needle compared to control, which was consistent with the decrease in percent needle loss with increasing shaking duration. Baled trees lost 13% more needles compared to control, but percent needle loss was observed to decrease with increasing number of trees in a bale. These trends corresponded with increasing ethylene and VTC evolutions, where the longer the shaking duration or larger number of trees in a bale, the higher the ethylene and VTC evolutions. One can therefore draw inference that mechanical perturbation as a result of shaking and baling induce biosynthesis and

Abstract:

Background: Kalanchoe integra is widely used in folklore medicine as an antiasthmatic agent. Previous studies have shown the ameliorating effect of Kalanchoe integra leaf extract [KILE] on bronchial hyperesponsiveness and inflammation. Further, the stabilizing effect of Kalanchoe sp on mast cell degranulation, suggests that Kalanchoe species are suitable candidates for allergic asthma therapy. This study is designed to investigate the anti-asthmatic potential of KILE and monitor the accompanying histopathological and immunobiochemical changes that occur in an animal model of bronchial asthma using ovalbumin sensitized guinea pigs. Method: Thirty male guinea pigs were divided into five groups of six animals each. Bronchial asthma was simulated in guinea pigs using ovalbumin. Both low dose (300 mg/kg) and high dose extract (900 mg/kg) were administered daily for 42 days. Prednisolone (2.5 mg/kg) was the standard drug used. Results: Guinea pigs in all KILE treated groups maintained the integrity of their airway structures: bronchial folds and walls, alveoli, alveolar ducts and sacs. KILE and prednisolone caused a reduction in immune parameters (p < 0.001), extent of bronchoconstriction, bronchial wall thickness and goblet cell accumulation in the sensitized guinea pigs. Conclusion: This study demonstrates the anti-asthmatic potential of KILE during prolonged administration by the oral route.

Abstract: In Ghana, the granitoids rocks are in two different groups, thus the basin type granitoid and the belt type granitoids. These granitoids have been studied petrographycally mineralogically and geochemically, especially the belt-type granitoids since it is the major host of gold occurrences in Ghana, however there are little studies on the petrogenesis and emplacement conditions of this important rock. In this paper we present the lacking knowledge on the emplacement conditions (temperature, pressure and the oxygen fugacity) of the basin-type granitoids in the winneba area of Ghana.The calc-alkaline basin-type granitoids in the Winneba area is composed of quartz+ plagioclase +potash feldspar+ alkali feldspar+ Biotite+ Hornblende +amphibole+ titanite. The plagioclase composition ranges from Ab58 An1.7 Or0.45 to Ab98 An41 Or41 and mainly in the field of albite and oligoclase. The amphiboles however have a compositional range of Mg/(Mg +Fe) ranging from 0.52 to 0.62 and a Si content of 7.1 to 7.4 atom per formula unit (afu). Their end-member compositions in the classification diagram are controlled by Magnesio-Hornblend, tschermakitic-Hornblend, and tschemakite substitution types. Scanning Electron Microscope (SEM) analyses of coexisting hornblende and plagioclase (hornblende-plagioclase thermometry), Al content in hornblende (aluminum-in-hornblende barometry) and the assemblage titanite-magnetite-quartz were used to constrain the P, T and fO2 during the crystallization of the parent magmas. The estimated temperature indicated an average temperature of crystallization of 677oC reflecting late crystallization from highly oxidized magma (log fO2 -20 bars).The rocks were emplaced at an average pressure of 2.2 kbars corresponding to approximately 8 km depth of below the crust.

Business and Economics Journal , 2012,
Abstract: This study estimates the efficiency levels of firms in the manufacturing sector of Ghana using a single-stage stochastic frontier technique. A five-year panel data of 135 observations made between 2005 and 2009 are considered. The results show that the frontier model instead of the traditional average response (OLS) function is an adequate representation for the data. Findings reveal that employment, capital, corporate governance, ownership, and years of firm operation/experience have reasserting influence on the productivity of the firms. However, research and development and time which are used as a proxy for technological progress are found to have negative influence on the firm’s output. The combined effects of factors involved in the technical inefficiency model are responsible in explaining the level and variations in the production of the firms in Ghana, although individual effects of some variables are not significant. Over all, private firms fared better. However, the predicted mean technical efficiency is estimated to be 38 percent. This finding indicates that there is high potential for increasing firm’s output by an average of 62 percent in the short-run without anyadditional resource by adopting the practices of the best firm.
Major Improvements of Quartz Crystal Pulling Sensitivity and Linearity Using Series Reactance
Vojko Matko,Riko ?afari
Sensors , 2009, DOI: 10.3390/s91008263
Abstract: This paper presents a new method of substantially improving frequency pullability and linearity using reactance in series with an AT fundamental crystal operated with a series load capacitance in the range of 3 to 50 pF and frequencies in the range of 3.5 to 21 MHz. The research describes high quartz pullability and linearity by varying the load capacitance. The paper also gives impedance circuits for crystal unit (3.5 MHz) together with load capacitance and compensation reactance. The experimental results show that the new approach using compensation method of quartz crystal connected in series reactance increases the frequency pulling range by ×25 to ×100 depending on the type of oscillator and compensation factor ?k? in the temperature range of 10 to 40 °C.
