Comparability of the proximate and amino acids composition of maggot meal, earthworm meal and soybean meal for use as feedstuffs and feed formulations
Levels of proximate and amino acid compositions were determined in Maggot meal (MM), Earthworm meal (EM) and Soybean meal (SM). Maggot meal was best in Ile, Leu, Lys, Try, Asp, Cys and Pro whereas Earth worm meal was best in Arg, His, Met, Phe, Val, Glu, Ser and Tyr while Soybean meal was only best in Gly, when compared on pair-wise basis. The total amino acid contents were: Maggot meal (58.4g/100g crude protein), Earthworm meal (56.3g/100g crude protein) and Soybean meal (34.9g/100g crude protein) and an average of 49.9g/100g crude protein with respective essential amino acids of 34.5g/100g crude protein, 31.4g/100g crude protein and 18.3g/100gcrude protein. The Predicted Protein Efficiency Ratio (P-PER) levels were: 2.16 (Maggot meal), 1.45 (Earthworm meal) and 1.14 (Soybean meal). On average basis, the limiting amino acid based on whole hen’s egg amino acid scoring pattern and Provisional amino acids scoring pattern was threonine. However, significant differences occurred between Maggot meal/Earthworm meal (MM/EM), Maggot meal/Soybean meal (MM/SM), Quality of amino acid (QAA) of Maggot meal/ Earthworm meal (MM/EM) and Maggot meal/ Soybean meal (MM/SM) at r = 0.05 and n-2 degree of freedom. When comparing the quality of amino acids of feedstuffs on pair wise basis, the coefficients of alienation (CA) were fairly low (24.0 - 40.7%), meaning that there is a better relationship between them while on the other hand the Index of Forecasting Efficiency (IFE) values were very high (59.4 – 76.0%) indicating that the error of prediction was very low. The three feedstuffs could then be compounded in other to employ them in feed formulation for fish, poultry and other animals.

Corrosion Inhibitive Effects of Extract of Leaves of Tylophora Indica On Aluminium in HCl
Corrosion is a natural process which converts a refined metal in to a more chemically stable from. It is the gradual destruction of material by chemical of electrochemical reaction with their environment. It can be prevented if the metal is coated with something which does not allow moisture and oxygen to react with it. It can be controlled by either sacrificial protection or by antirust solution. The naturally occurring plant product are ecofriendly, compatible, non polluting, less toxic, easily available, biodegradable so can widely be use without side effect. Tylophora indica has been selected for the study to it’s corrosion inhibition efficiency. It is easily available in any season. It is also called annatmul. It is endemic to southern and eastern part of india. Is it used for the treatment of jaundice, inflammation ,dermatitis and rheumatism. It contains septicine, isatylocrebrinsterol,wax,tylophorinicine.Corrosion inhibition efficiency of leaves of Tylophora indica was studied for aluminium in HCl solution.

Culture and Maternal Health: A Study Of Oruagu and Nnewichi Women of Reproductive Age Between 15-49 Years in Anambra State
For women of childbearing age, the major challenge is the risk of maternal death as a result of poor health during pregnancy and childbirth. This study explores socio-cultural factors and their implications on maternal health in rural communities in Nigeria using Owukpa community and Obollo-Eke community as study areas. The data were generated from a cross sectional survey of mothers aged 15-49years in both communities whether married or unmarried. A cluster random sampling procedure and non probability sampling were adopted to select 572 respondents for the study, out of this 560 constituted the questionnaire which was the major instrument for data collection, and 12 was based on in-depth interview guide. The result shows that most of the factors identified have serious implications for maternal health in the two communities though the degree at which the factors affect health varied. The factors include; education, poverty, nutrition, lack of basic social amenities, inadequate and inaccessible health care services, lack of family planning, low status of women, gender base violence, and paternity pattern. The study revealed that paternity pattern practised in the two communities differed, The result also shows that certain attitudes like; early marriage, delay in seeking service, sex preference and desire for many children, and sexual activities among the unmarried affect the health of women however with certain degree of variations among the two communities.

Determination of Levels of Organochlorine Pesticides in Plastic Resin Pellets on Selected Beaches in the Greater Accra Region of Ghana
Abstract The levels of Organochlorine Pesticides (OCPs) in plastic resin pellets were determined with the objective of assessing the status of OCP pollution in the marine ecosystem of selected beaches in Ghana (namely Art Centre, Sakumono, Osu Castle, Labadi, Korle-Gonno, Independence Square and Tema Mighty beaches). The plastic pellets were subjected to Soxhlet extraction and the extracts analyzed using Gas Chromatograph coupled with electron capture detector. High concentrations of Dichlorodiphenyltrichloroethane compounds (DDTs) were recorded followed by Hexachlorocyclohexane (HCHs), Chlordane compounds (CHLs), Hexachlorobenzene (HCB), Aldrin, Dieldrin, Endrin (DRINs), alpha-endosulphan, beta-endosulphan, endosulphan sulphate (Endosulphans) and Methoxychlor. Analysis of the virgin pellets recorded no organochlorine pesticides present. However, plastic pellets collected from all seven beaches were found to contain OCPs with the highest recorded on the Art Centre beach with a total OCP concentration of 106 ng/g. Plastic pellets collected on the Labadi beach recorded the lowest OCPs with a concentration of 20.2 ng/g. The accumulation of OCP residue on the plastic resin pellets suggests that it can be used as a tool for monitoring marine pollution. Key words: Plastic resin pellets, organochlorine pesticides, beaches, concentration, Ghana.

Development Strategies for Privately Owned Fashion Boutiques in southeast United States
In the fashion business, privately owned brick-and-mortar fashion boutiques in the United States face the challenge of competing with online retailers who usually have low overheads and inventories. The knowledge and awareness of the changing marketing landscapes responsible for the decline in the survival rate of traditional or brick-and-mortar fashion boutiques may be essential to traditional and online entrepreneurs, to increase adaptability and business sustainability. Grounded in the general systems theory, the research conducted through the invocation of a qualitative multiple case study, entailed the exploration of strategies used by successful brick-and-mortar fashion boutique owners in contending with the online retailers. Interviews constituted the means for data collection and involved 5 brick-and-mortar fashion boutique owner participants, who operated retail fashion businesses in the southeast region of the United States. The successful existence of the business for more than 5 years, while participation criteria in the study, also indicated merit in studying success in traditional fashion retailing. The primary data from interviews were analyzed and triangulated with credible secondary sources such as information and reports from the U. S. Small Business Administration, U. S. Census Bureau, and fashion industry sources. From a thematic analysis of the interview data, the three themes that emerged from the data analysis were the importance of business success of marketing strategies, cognizance of fashion trends, and the role of customer preference in economic success. The potential knowledge from the utilization of the study results may serve to increase the success rates of traditional and online fashion startups and possibly endow these businesses with the adaptabilities and strategies capabilities in the inevitable greater transformation to an online business world.

Devising an Appropriate Breeding Strategy for Different Crops to Face the Challenge of Climate Change
Work on global warming is expected to have significant impacts on conditions affecting agriculture, including temperature, carbon dioxide, glacial run off, precipitation and the interaction of these elements has been reviewed in this article. To a large extent, the overall effect of climate change will depend on the balance among these factors. Assessment of the effects of global climate changes on agriculture will help to properly anticipate and adapt farming systems to maximize agricultural production. There is exponential rise in atmospheric carbon dioxide. Atmospheric concentration of carbon dioxide was 270 ppm during pre-industrial period and human activities have added more than 100 ppm and it has reached 380 ppm with the rate of rise as high as 1.8 ppm per year. With this exponential rise in carbon dioxide, its concentration will double by the middle of 21st century. The effects of an increase in carbon dioxide would be higher on C3 plants (such as wheat) than on C4 plants (such as maize), as the former is more susceptible to carbon dioxide deficit. Increased CO2 leads to fewer stomata development in case of plants which results in less water usage. It is estimated that under optimum conditions of temperature and humidity, the yield increase could reach 36 % if the levels of CO2 are doubled. A large number of stress responsive genes have been cloned and sequenced from a number of crop plants. A common feature of many stress induced proteins is that their transcripts are induced not only by stress but also by (ABA) abscisic acid. It implies that there is a general role for ABA in the signal transduction pathway i. e. from sensing of the environmental stress and thereby leading to gene expression.

DSP algorithm for music-less audio stream generation
In this paper we investigate the problem of separation of human voice from a mixture of voice and different music instruments. The human voice may be a part of singing voice in a song or it may be a part of some news broadcasted by a channel and it contains background music. The final outcome of this work is a file containing only vocals. In our approach we consider stereo audio for separation. We process the signal in time frequency domain. In our method of blind source separation we processed the input stereo audio file in the form of frames, windowed them and then applied discrete Fourier transform (DFT) on signal. Then the signal is masked for de-mixing purpose using time frequency filters and non-zero DFT coefficients that are estimated as a part vocals are selected and signal is reconstructed by overlap add (OLA) method to get the final output signal containing only vocals.
