Abstract
Dragonflies (Odonata: Anisoptera) are beautiful insects with high species diversity worldwide. These insects are indicators of environmental pollution and are predators of important insect vectors of human pathogens and parasites, especially mosquitoes. The present research was the first record of 318 specimens of dragonflies from district Lower Dir (LD), Khyber Pakhtunkhwa, Pakistan collected during May-July 2011. Among the specimens collected there were 11 species, 7 genera and 3 families. The number of specimens collected in each family were 17 Cordulegasteridae (5.3%), 18 Gomphidae (5.7%), and 283 Libellulidae (89.0%).  All cordulegastrids were the golden ringed, Cordulegaster brevistigmata brevistigmata Selys. All gomphids were Clubtails, Onychogomphus bistrigatus Selys. Libellulids species were: blue or black percher, Diplacodes lefebvrei (Rambur); ground skimmer, D. trivialis Rambur; black tailed skimmer, Orthetrum cancellatum (L); common red skimmer, O. pruinosum neglectum (Rambur); slender skimmer, O. sabina (Drury); triangle skimmer, O. triangulare triangulare (Selys); wandering glider or global skimmer, Pantala flavescens (Fabricius); spine legged redbolt, Rhodthemis rufa (Rambur) and common skimmer, Sympetrum decoloratum Selys. A dichotomous key based on external morphology, coloration and wing venation was prepared to facilitate the identification of the dragonfly fauna of the LD and aid conservation efforts of dragonflies in Pakistan.

Well Log Sequence Stratigraphic and Palynological Analysis of Late Miocene to Pliocene Agbada Formation, Southwestern Niger Delta Basin, Nigeria

Research Article
Author(s): Olajide Femi Adebayo
Journal: Review of Environment and Earth Sciences

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Sequence stratigraphic interpretation of Chev-1, 2, and 3 wells offshore western Niger delta basin was carried out based on the vertical relationship of the lithofacies associations, electronic well-log, palynologic and foraminiferal data and the existing stratigraphic framework of the Neogene succession in the Niger delta basin. Each well was analyzed in terms of the system tracts, maximum flooding surfaces and sequence boundaries. The recovered palynomorphs together with planktonic foraminifera suggest Late Miocene to Pliocene age. The palynological assemblages exhibit cyclic changes which are here related to the sedimentary evolution.Eighteen depositional sequences were recognized; there are five in Chev-1, ten in Chev-2 and seven in Chev-3. Three of those in Chev-1 and Chev-2 are correlatable while one is correlatable between Chev-2 and 3. These sequence stratigraphic data are matched with existing global standard biostratigraphic zonation scheme and global eustatic curve in order to allow a correlation of sequence beyond local and regional scales.
Contribution/ Originality
The study contributes to the existing literature on the Niger Delta Basin by integrating sedimentology, biostratigraphy, well logging and sequence stratigraphy to detect depositional sequences that can serve as reservoirs to substantially increase the oil reserves in the basin. It documents eighteen sequences based mainly on palynological signature in the basin.

Abstract
Iron metabolism is closely related to carcinogenesis. In this study, iron, ferritin and TIBC were analysed in 30 patients of early stage, 30 of advanced stage breast carcinoma before and after treatment and the results were compared with 30 healthy controls. The levels of all the three parameters were found to be significantly higher in breast cancer patients as compared to healthy controls and patients with advanced disease showed greater values as compared to early stage disease. These levels decreased after treatment and the difference was more significant in patients with complete response. Serum analyses of iron, ferritin and TIBC may help in assessing the severity and prognosis of the disease.
Contribution/ Originality
This study contributes in the existing literature regarding association of iron metabolism and carcinogenesis. The principal role of iron profile analysis may be in asessing the severity and monitoring the treatment of breast cancer patients.

Journal: Journal of Challenges

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The present study conducted systematic reviews and meta-analyses of relevant literature and data relating to gun violence in United States of America and found that the current concern about gun violence arises from a growing understanding of the adverse economic, physical, mental, and behavioral health effects that result from community exposure to high rates of gun violence. Therefore, it is noted that gun violence has become a major socio-economic and public health issues in United States of America due to the fact that it has eroded the quality of life of majority of the citizens. The study therefore established that interventions and strategies to address the problem of gun violence should address the intransigent causes of American gun violence - dying cities, inequality, deteriorating family structure, and the all-pervasive economic and social consequences of a history of slavery and racism that provides a generally acceptable strategy for reducing incidents of gun violence.
Contribution/ Originality
The purpose of this study is to enhance an understanding of the concerns that gun violence pose to contemporary United States of America society. The current study may have implications for policy makers and administrators seeking strategies to address the problem. Therefore, this study contributes to existing literature by seeking to provide a better understanding of the widespread incidents of gun violence in the United States of America.

Abstract
Aims: To examine the effects of the administration of CD on lipid metabolism and liver enzymes in hyperlipidemic subjects. Study design:  20 subjects were divided into two groups, each containing ten subjects. Each subject in the 1st group ingested 1g, while the subject in the 2nd group ingested 2g of CD powder as a broth suspension in a single daily dose before lunch during the follow up period of one month. Patients kept their individual diet relatively constant. Methodology: We included 20 hyperlipidemic volunteers (men; age range 20-50 years) of a total of 80 subjects. Blood samples were taken and analyzed for total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), Low density lipoprotein cholesterol (LDL-C), atherogenic index (AI), serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). Results: The results of the present study show a significant decrease in the levels of TC, LDL-C and TG in 1g and 2g of CD administration groups by 12.6, 24.1, 17.1% and 19.9, 25.5 23.4% respectively while the level of HDL-C was significantly increased by 45.6 and 32.5% in 1g and 2g respectively.  The atherogenic index (AI) was significantly decreased in 1g and 2g groups by and 47.4% and 45.5% respectively. Our results also show that, CD administration in 1g and 2g subjects causes a significant decrease in ALT and AST by 39.2, 32% and 48.5, 33.3% respectively while the level of ALP was non-significantly decreased. Conclusion: dietary supplementation with CD administration decreased serum lipid profile and liver enzymes in hyperlipidemic subjects. Therefore, it may be regarded as a useful therapy for hyperlipidemia and liver disease. However, further studies are required to compare it with other medicinal plants and with lipid lowering drugs.Place and Duration of Study: Department of Chemistry, Ibb University, Yemen, between February to June 2012.
Contribution/ Originality
This study is one of very few studies which have investigated the Effect of Dietary Supplementation with Cyphostemma Digitatum on Serum Lipid Profile and Liver Enzymes in Hyperlipidemic Subjects (human) and we found that, dietary supplementation with CD administration decreased serum lipid profile and liver enzymes in hyperlipidemic subjects.

Abstract
 Zingerber offinale (ginger) is an underground stem or rhizome which is known to have originated from Asia and have been reported to have a number of medicinal properties which is used in the treatment of many ailments such as arthritis, painful menstrual periods, nausea etc. It is also used as a common specie in food and bakery industries. Due to the availability and medicinal uses of ginger, the effect of the ethanolic extract on the histology of the pancreas of adult wistar rats was investigated. Twenty five (25) adult Wistar rats weighing 125-200g were divided into five groups (A, B, C, D and E) each with five rats. The animals in group A and B served as control groups and received distilled water and olive oil respectively, the animals in groups C, D and E served as experimental groups, and received 100mg/kg, 250mg/kg and 500mg/kg body weight of the ethanolic extract of Zingiber officinale respectively. The animals received the extract for 14 days and were sacrificed 24 hours after the last administration and routinely processed histologically. The study shows that there is disintegration of the islet cells of Langerhans (IL) with pyknotic nuclei, but no visible change or alteration in the serous acini (SA) of the pancreas. It is observed that extract of ginger has adverse effect on the integrity of the islet cells of Langerhans.

Abstract
The present study was carried out to investigate the effects of Punica granatum peel extracts and Ammi visnaga fruit extracts on the Acetylcholinesterase (AChE) activity in haemolymph and fat bodies of last instar nymphs and newly emerged adult females of Schistocerca gregaria. The extracts of both P. granatum peel and A. visnaga fruit predominantly enhanced the enzyme activity in haemolymph of nymphs and adults with few exceptions. The disturbance induced due to P. granatum peel extracts on AChE activity in fat bodies depended on both nymphal age and developmental stage. Where, although remarkable increase in AChE activity was detected in the mid- and late-aged nymphs, serious decrease was noticed in early-aged nymphs and adults. A. visnaga fruit extracts prohibited the early-aged nymphs to attain the normal enzyme activity in their fat bodies but promoted the nymphs of other ages to gain high activity. In fat bodies of adults, n-butanol extract of A. visnaga caused a pronounced inhibition of the enzyme activity but other extracts promoted for considerable increasing activity.
Contribution/ Originality
This study documents the probable candidates for the development of biopesticides, as alternative to the hazardous synthetic insecticides, from extracts of Punica granatum peel and Ammi visnaga seeds for controlling the dangerous desert locust Schistocerca gregaria by the disturbance of acetylcholinesterase activity and all physiological process depending it.

Abstract
This study on the analysis of determinants of demand and supply of maize was conducted in Aniocha North Local Government Area, Delta State with particular emphasis on some selected villages in the Local Government. The study covered forty maize producers randomly selected from eight villages from randomly selected two clans in the study area. Frequencies, means percentages and chi-square statistics were employed in the determining the data obtained. Chi-square statistics was used to ascertain whether socio-economic factors are significant determinants of demand and supply of maize in the study area. The result shows that the value of C hi-square calculated (2.45) < chi-square critical value (14.1) at five percent level of significance with degree of freedom of seven as was conducted. This implies that socio-economic characteristics were not significant determinants of demand and supply of maize. The result agrees with the null hypothesis which says that socio-economic characteristics are not significant determinants of demand and supply of maize in the study area. Hence it was accepted. 
Contribution/ Originality
The study is one of the very few studies which have investigated the determinate of demand and supply of maize in Aniocha South Local Government Area, Delta State, Nigeria.

Abstract
The study examined the marketing of fresh fish in Ngaski Local Government Area of Kebbi State, Nigeria. With the aid of a sampling frame, proportionate random sampling technique was used to select fish marketers. Thus, a total of one hundred and ten (110) fish marketers constitute the sample size for the study. Structured questionnaire was used to collect data for the respondents. Data analysis was carried out using descriptive statistics, marketing efficiency, marketing margin and T-test statistics. Result of the study revealed that about 26% of fresh fish marketers in the study area were within the age range of 20 to 30 years, fresh fish marketing in the study area is dominated by males (71.9%). Furthermore, about 83% of fresh fish marketers in the study area were married; majority (85.4%) of fresh fish marketers in the study area were literate. About 72% of fresh fish marketers in the study area had their monthly income ranging from N2, 000 to N20, 000. Also revealed from the result, 38.1% of fresh fish marketers in the study area had fresh fish marketing experience of 6 to 10 years. Result further showed that marketing margin of an average fresh fish marketer was N190 and the percentage marketing margin was 30%. The marketing efficiency of fresh fish in the study area was 0.582 and percentage marketing efficiency was 58%. Majority (63.64%) of fresh fish marketers buy fish directly from the fishermen and retailed it to consumers. On the problems faced by fresh fish marketers in the study area, 58.2% reported that fish spoilage was the major problem of fresh fish marketing. There was significant difference between the retail price and the river bank price of fresh fish in the study area. It could be concluded that fresh fish marketing in the study area was profitable and that fresh fish marketing in the study area was inefficient. It is therefore recommended that research institute such as national centre for agricultural mechanization should develop simple, affordable and easily adoptable equipment for fresh fish storage and preservation to avoid spoilage and loss.
Contribution/ Originality
This study contributes to the existing literature in fish marketing and will provide empirical information to policy makers in the formulation of appropriate policies. It will also serve as a guide to practicing and prospective fish marketers and to researchers who may investigate further into the subject matter.

Abstract
The study was carried out in Anambra State, Nigeria to assess the influence of human capital attributes on occupational diversification among rural women. Simple random sampling technique was used in selecting 462 respondents for the study. Data was collected using questionnaire. Descriptive statistics such as percentage mean scores, standard deviation; factor analysis and correlation were used for data analysis. Results show that the respondents were mostly influenced by certain human capital attributes namely; possession of entrepreneurial skills (59.5%), number of dependants in the household (55.4%), access to information on changing demand patterns (52.6%) 52.4% and perceived health status (52.4%). They were also highly constrained by lack of women empowerment training programmes in rural areas (M= 3.5), poor skill training (M= 3.5), inadequate training opportunities (M= 3.4), poor educational attainment (M= 3.3), among others. Developing skills in rural women are keys to improving rural productivity, employability and income-earning opportunities, enhancing food security and promoting environmentally sustainable rural development and livelihoods. It was recommended that adult literacy programmes should be introduced by government and non-governmental organizations in order to help the rural women to acquire necessary education that will help them in occupational diversification. It highlights the development of human capital among rural women in order to equip them with the necessary skills to work in various occupations gainfully employed for higher returns.
Contribution/ Originality
This study is one of very few studies which have investigated human capital attributes influencing rural women in occupational diversification. The economic planning assumption is that all rural people are involved in agricultural production, but social changes show that rural women are also involved in non-farm occupations and are highly influenced by human capital attributes.

Abstract
Cadmium (Cd) contamination form tailings disposal that occur in tin mining in Bangka cause a serious  soil health problem. One of the ways to reduce Cd concentration in soil is bioremediation. The research was conducted to determine the influence of fungi and cattle manure on dry weight and Cd content of  maize  as well as  fungi  population in the rhizosphere of maize grown in tailing collected from tin mining area in  Bangka. Green house research was set up in Factorial Randomized Block Design. Maize hybrid P21 was grown  for six weeks in tailing  contaminated by CdCl2.0,5H2O up to 8 mg kg-1 and inoculated with  Humicola sp. or Fusarium sp. without and with several dose of cattle manure. Interaction effect between fungi and cattle manure clearly affect the rhizosphere fungal population, however did not give any significant effect to dry weight and Cd content. Application of Fusarium sp. 107 spores mL-1 with manure of 22 g pot-1 lead to increased fungal population. There was an independent effect of cattle manure to decrease Cd content and increase dry weight of maize. 
Contribution/ Originality
This study contibutes in developing the soil microbiology and soil bioremediation studies in Indonesia. This study also as a reference and an information about what kind of fungi and the right dose of cattle manure to improve soil quality and productivity in tailing at Bangka Island.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The potential link between governance and institutions is increasingly becoming a central concern in social science. In political science, the approach taken to explore this link involves examining the role structure plays in determining political behaviours, the overall patterns of governance, and the outcomes of political processes. Therefore, the quality of institutions has long been recognized as an important component of a well-functioning system of governance.  This paper investigates and reflects on the relationship between institutions and governance in local political settings and analyzes the impacts of institutional factors on good governance. Very specifically, the paper explores different theoretical and empirical debates about governance in general and good governance in particular. Drawing upon “historical institutionalism”, the paper offers a satisfactory analytical framework for studying the ability of the institutions of governance in Tanzania, from their inception through their development over time, to meet the needs of the local community.
Contribution/ Originality
This paper has primarily indicated that analyzing local governance in Tanzania and other developing nations brings strongly into focus the nature of the relationship between institutions and the quality of service provision at the local level. This analytical approach not only helps to provide objectives and meaning for good governance, but also offers a path to understanding the fundamental shortcomings of the institutions of governance. The paper concludes by arguing that, the problems of governance in Tanzania and likely in other developing nations of Africa is not a lack of sound development policies, but rather the institutional mechanisms necessary to implement or translate those policies into desirable results.

Abstract
Small businesses in the informal sector are increasingly being recognized as generating meaningful and sustainable employment opportunities for women in Zimbabwe. However, women operating small business face many challenges that negatively impact on the viability of those businesses. In order to mitigate those challenges women in small catering business at Siyaso Magaba home industrial area in Mbare Township in Harare (simply known as Siyaso), employ a number of strategies that enable them to survive and continue operating. This paper presents findings from a research carried out at Siyaso to identify those challenges and survival strategies. The challenges include lack of funding, lack of business management skills, stiff competition, stringent requirements for registering a business, defaulting customers and difficulties in balancing work and domestic commitments. These are the challenges that informal business operators have to grapple with in Zimbabwe in general. Over and above these challenges women at Siyaso also face specific challenges that include poor infrastructure in the business area, unaffordable rentals and lack of basic amenities.  In order for the women operating catering business at Siyaso to survive they apply a number of strategies which include borrowing money from relatives at no interest being charged, taking turns to give each member an agreed amount of money every month, purchasing s applies on a daily basis instead of buying in bulk, purchasing food items on credit, borrowing from loan sharks and serving extras to clients as a way of luring them from competition. The study concludes by suggesting that in order for the businesses to improve their performance the women should form themselves into a cooperative and register it. They should continue offering a wide variety of meals to customers so as to compete better. The Harare City Council should establish more premises which can be rented at affordable rates from which women can conduct their catering businesses. The city council should also improve amenities at Siyaso Magaba home industrial area.
Contribution/ Originality
This study is one of the very few studies which have investigated the challenges that women running small businesses in Zimbabwe face. It documents those challenges and the strategies that the women use in order for them to survive in the harsh economic environment as they try to empower themselves.

Abstract
This paper on political economy of entrepreneurship draws insights from creative writings of Chinua Achebe and Linus Asong to argue that, contrary to Marxist optimisms and idealisms, the business of political entrepreneurship is so complicated because it intersects with multiple conflicting narratives. These narratives of empire take new different and often times contradictory directions such as neo-pariarchalism, the popularity of anarchism, limitations of the intelligentsia class. religion as substitution, issues of feminist labour power and  social class questions.
Contribution/ Originality
Business entrepreneurship scholarship divides knowledge into studies on individual attributes of entrepreneurs and events like risk-taking (Kihlstrom and Laffont, 1979) and achievement (McClelland, 1961) and studies on economic environment (Tushman and Anderson, 1986). This study contributes to the field of business entrepreneurship by amalgamating both approaches into one which recognizes its economic base and  political events.

Abstract
The gradual inclusion of the participation of the public in museums through social networks and other tools that enhance the user’s leadership in the management of information and in the knowledge production seems to have led to an evolution in the cultural experience of the public. However, we do not know yet whether the possibility to intervene and manipulate the content really optimize the communication between visitors widening their possibilities of action turning them into a concerned and active audience.  In this study, we have analyzed practices and motivations of on line audience, detecting some guidelines that should be considered when incorporating user participation in heritage institutions. The analysis of when a participatory environment can encourage the dissemination of the contents of the museum and engage audiences in an ongoing and repeated relationship that encompasses even the attendance realm, was performed using a qualitative methodological perspective though supported by some quantitative data related to the profiles of the recipients of cultural activities and their practices in the network. The suggestions proposed, by virtue of being the result of an evaluation process of public preferences, would highlight the real needs of on line visitors and reduce the dissociation between the way that museums seek to use their pages and effective practices of their users. Looking at these results, this research (based on the analysis of four case studies) represents an attempt to approach the strategies adopted by the institutional sphere in relation to the new social media and to the current needs of the public.
Contribution/ Originality
This study documents the digital strategies used by museums of art and design to communicate with their audiences. The paper’s primary contribution is finding those that elicit a positive response from the general public and the factors that are linked implicitly to their success.

Abstract
The municipality of M’rirt located in the eastern part of central Morocco, in response to the scarcity of water resources in food, the national Office of Drinking Water has used the coagulation-flocculation for water treatment of Oum Errabia River, process of removing the most delicate phase in suspension by the addition of a body chemical called coagulant. The application of coagulation flocculation process for the treatment of surface water is an interesting alternative as the treatment is fast, cheap and allows obtaining perfectly clear water can fill the deficit in water. In the case of our study, we chose the coagulation-flocculation with aluminum sulphate and ferric chloride in order to compare their effectiveness in the elimination or reduction of turbidity on the one hand, and On the other hand see the effectiveness of aluminum sulfate in an acid pH range. The tests are performed in the laboratory and were conducted using a jar test. Ferric chloride showed an effective reduction of the turbidity of water from the aluminum sulfate at low concentrations. The reduction in turbidity of the water by the aluminum sulphate is higher in acid pH (pH 5.5) according to the results obtained from the tests.
