Abstract
This paper analyzes environmental conservation and use of economic incentives to conserve biological resources in Nigeria. Conservation refers to the management of human use of the biosphere so that it may yield the greatest sustainable benefit to present generations while maintaining its potential to meet the needs and aspirations of future generations.  Its compliments are preservation, maintenance, sustainable utilization, restoration and enhancement of the natural environment.  It is concerned with plants, animals, microbes, and with the non-living elements of the eco-systems which sustain them.  The varieties of ecological system in Nigeria create an endowment of biological resources of which the nation is justifiably proud of.  The conservation of these resources for the benefits of the present and future generations has been practiced with little attention given to develop a crop specialist (ecologists) to handle the subject.  Under this situation the urgency of conservation programmes can no longer be denied.  The establishment of the National Resources Conservation Council by the Nigerian Government is a welcome idea.  Working together, it should be possible to achieve the goal of conservation namely that human survival and sustainable economic development depend fundamentally on proper maintenance of renewable resources; vegetation and forest, water, marine and fisheries resources as well as wild animals and soil  resources. The paper finally looks at the values of biological resources, the cost of protecting biological resources and the status of conservation practices. 
Contribution/ Originality
This study is one of the very few empirical studies which have investigated environmental conservation and use of economic incentives to conserve biological resources in Nigeria. The paper employs descriptive method of analysis on the use of economic incentives to conserve biological resources. The paper’s primary contribution is in the area of the existing literature on environmental conservation and resources management.

Abstract
The lifting wire ropes are hierarchically complex structures, very helpful and widespread in heavy manufacturing roofs, lifting systems, mining industry, offshore structure, electric lines, elevators, suspension bridges and transmission towers. Generally, the metallic cables structure provides solutions particularly interesting and spectacular to current problems faced by industries, which are called regularly to perform tasks for mechanical handling in steps of manufacturing product. The repetitive nature of these tasks, rather than decreasing the risk of accidents, helps to accentuate them by a sort of addiction to risk.In this context, the wire ropes are a prime target of brutal damage, compared to conventional structures. More generally; the sudden failure is the major cause of cables degradation. Industrial experience shows that the failure of much of their hoisting ropes in use is most commonly due to cumulative damage of wires. This is particularly insidious due to its hidden nature; it can lead to significant reduction in strength capacity of wire ropes over time, which can sometimes lead to their total or partial rupture.In order to optimize the residual resistance loss of a lifting wire rope, we propose a study of rupture impact of its wires on the loss of residual strength elastic. The results of tests allow a comparison between the loss of ultimate strength and residual strength loss residual elastic, so as to determine the normalized resistance and estimate the damage. The results of this work would be operated to establish the bond between reliability as being a statistical size and the damage by artificial damage observed and caused by cyclic requests.

Journal: Humanities and Social Sciences Letters

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper examined the accessibility of healthcare services to the people in the South Eastern Nigeria. The reason behind the study is to assess how the people make timely use of the health services according to their need. This is related to physical distance and travel time from service delivery point to the user and also how the healthcare services are able to cover the population of the study area. Data used were obtained from National Bureau of Statistics and the population commission. Data revealed that there are more privately owned health facilities in the area. It also revealed that the total number of hospitals (government, private and community owned hospitals put together do not adequately cover the population of the area they are meant to cover. These inadequate health facilities have implications for the total health status and wellbeing of the indigenes of the south east. Recommendations were made on how to tackle this inadequacy if the millennium development goals will be realised.
Contribution/ Originality
This study gives a clear picture of the healthcare facilities in the South East vis a viz the population of the area. It equally serves as a guide and reliable source of information to the government and other stakeholders so that adequate healthcare facilities be provided for the study area.

Various Influence of Active Сhemical Additives on Hydrogen and Hydrocarbons Combustion

Research Article

Journal: International Journal of Chemistry and Materials Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
It is experimentally revealed that the methane combustion inhibitor CCl4 shows no effect on the lower ignition limit of hydrogen combustion. It is established that small amounts (~10-1 %) of chromium hex carbonyl promote combustion of 2H2 + O2 mixture, which manifests itself in increase in the propagation velocity of the flame, thus inhibition of oxidation of isobutene by this additive takes place. Therefore the role of hydrogen atoms in hydrocarbon oxidation is not significant and may result at least in participating in longer reaction chains than in hydrogen oxidation. It means that the kinetic mechanism of inhibiting combustion of hydrocarbons by carbonyls suggested in the literature based on accounting for termination of hydrogen atoms should be refined.

Research Article
Author(s): Shaoying Zhang , Qin Li, Yulan Mao
Journal: Journal of Food Technology Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
 To prolong the shelf life postharvest jujube, the effect of carbon monoxide (CO) on senescence of postharvest jujube in relation to active oxygen metabolism was investigated. Jujubes were fumigated with CO gas at 5, 10, 20 or 40μmol/L for 1 h, and then stored for 30 days at room temperature. Changes in membrane permeability, malonaldehyde (MDA), H2O2, O2•− content, and activities of active oxygen metabolism associated enzymes including superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in fruit were measured. The results indicated that a little of CO could exhibit positive physiological effect on controlling senescence of winter jujube during storage. The study further showed that fumigating jujube fruit with 10 μmol/L CO could reduce increase of MDA content and the relative membrane permeability, effectively inhibit oxidative damage to lipids, decrease H2O2 and O2•− content and maintain high activities of SOD, CAT and POD. The present data suggest that exogenous CO treatment might delay the jujube fruit senescence by regulating active oxygen metabolism.
Contribution/ Originality
This study documents for the first time the effect of carbon monoxide (CO) on H2O2, O2•− content and activity of antioxidant enzymes (SOD, CAT and POD) in relation to active oxygen metabolism during senescence of postharvest jujube.

Abstract
Economic pressure and other pressure issues faced by small and medium sized companies (SMEs) require continuous improving of their capacities, of staff knowledge, of training and learning to survive or stay competitive. This issue is at the top of European, national and regional policies. But due to limited resources, often managers reduce learning activities and  using new technologies in their companies. Blended learning is a suitable way to learn in SMEs to increase their efficiency, to keep up competitiveness/surviving of the companies. Scenario-based learning is one method to be used in blended learning in order to improve learner engagement and problem understanding.Cloud computing is one of the emerging ICT trends in the past seven years. It has received much hype particularly in the past two years, with many companies considering the efficiency of cloud computing for their business, reduced costs, and easy access of data and particularly of new emerging ICT applications with little overhead.This paper contributes in the existing literature with results of interviews and case studies within projects aimed at problems of SMEs like suitable learning methods, advantages of cloud computing for SMEs efficiency and presents examples. The paper’s primary contribution is finding that blended learning is a suitable form for increasing competitiveness of SMEs and could be used also by introducing cloud services which will change the landscape of business also in SMEs in the next years.
Contribution/ Originality
The paper shows how European projects and cooperative work with participation of actors from different sectors can contribute to improving competitiveness and growth of SMEs

Dividend Policy Relevancy in Theoretical and Practical Economics

Research Article
Author(s): David Gordon
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The foremost purpose of this paper is to concisely explain to individuals teaching economics in an academic setting or using economics in a practical setting some of the basics of long run financial theory focusing on the dividend policy decision of a corporation. The main motivation for this study is based on observations of economists being very deficient in the discipline of finance especially in long run financial concepts. Many times practitioners or academics who are educated in the area of economics lack any type of background in finance and therefore are deficient with their knowledge of financial theory and applications. This disconnect prevents using many financial applications in their own classes, in their own businesses or with their own research. This paper serves as a primer to some of the long run dividend policy theories that individuals can use as a starting point to their additional research, study or use in teaching. Areas related to dividend policy and financial theory in general can be utilized by economists in academia and the private sector to enhance and advance their professional careers.
Contribution/ Originality
This study contributes in the existing literature by demonstrating the usual disconnect between the disciplines of finance and economics. The paper illustrates that economists can gain substantially from a basic knowledge of financial theory. The contribution here emphasizes the dividend policy decision that corporations must make.

S-Dimensional Assets Portfolio Evaluation

Research Article
Author(s): Luis F. Copertari
Journal: International Journal of Business, Economics and Management

Export to    BibTeX   |   EndNote   |   RIS

Abstract
An approach to calculate the upper limit to any given portfolio with s assets (corporate stocks or government bonds) in it is provided, which does not require the relative weight of each asset in the portfolio. The value obtained is contrasted with the traditional weighting approach to calculate the portfolio’s value. The process followed is the scientific method, starting with observation and hypothesis and after analyzing two examples, a synthesis is performed by generalizing the concepts and the main thesis that the Pythagorean approach here proposed constitutes an upper limit for the portfolio’s value.
Contribution/ Originality
This study uses a new estimation methodology to calculate the upper limit value of a portfolio of assets without the need to incorporate the weight of each asset. If there are no weights assigned to each asset, this upper limit may be the only way to calculate the portfolio’s value.

Abstract
This paper examined the influence of gender on job satisfaction among library staff in private university libraries in Ogun State, Nigeria. The survey research design was adopted for the study. The study population was made up of 162 library staff in seven private university libraries. Sampling was enumerative as all members of the population were given the opportunity to participate in the study. A questionnaire was used for data collected which was analyzed using descriptive and inferential statistics. Findings revealed moderate level of job satisfaction across gender with male making up 27.2%, and females 35.1% of the total percentage of 62.3% for job satisfaction. Gender was found to have no significant influence on job satisfaction while other factors such as stringent conditions for promotion, denied access to benefits and lack of job security were identified as major constraints to job satisfaction. Based on the findings, the study recommends that library administrators adopt a policy of equal treatment for each gender and review the conditions attached to promotion, among others as measures for enhancing job satisfaction.
Contribution/ Originality
This study contributes in the existing literature on job satisfaction among librarians. While a number of studies have considered various other factors that may or may not contribute to librarians’ job satisfaction, this study considered the gender dimension.  It has revealed that gender does not influence librarians’ level of job satisfaction.

Abstract
This paper examines forests diversity, their use pattern and management in the Eastern Himalaya with a case study of Mizoram state. The Eastern Himalaya is one of the bio-diversity hotspots of the world where the forest diversity varies from the tropical rainforest to temperate and alpine types because of the altitudes. In the case study area i.e. Mizoram, forest types vary from tropical evergreen forests to montane and temperate with rich biodiversity. Forests are lifeline for livelihoods sustainability in Mizoram as it is the second largest source of income after agriculture. Total forestland is 90.68%. They are conserved by the community people and the state forest department. Even, the whole country received decrease in forestland; Mizoram has registered about 1.4% increase. A study on forest cover and changes in the eight sister states of the Eastern Himalaya during the last decades was carried out to penetrate the current status of forest. Data from the secondary sources were gathered largely from the Forest Survey of India (FSI) 1991, 2001 and 2011. Similarly, data from the Department of Environment and Forest, Government of Mizoram on forest diversity and their distribution were also collected. Further, wide range of discussion was made with the officials working in the forest department and with the local people to elaborate the other aspects of forest resources such as use pattern of forest products. Personal observations on forest diversity use pattern and management of forest resources in Aizawl district was also carried out.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
Background. There is limited data on adjuvant treatment following surgery in patients with squamous cell carcinoma of the oral tongue. Aims. This retrospective study investigates prognostic value of different factors for local relapse-free survival (LRFS), regional relapse-free survival (RRFS), disease-free survival (DFS), and overall survival (OS) in patients with oral tongue cancer treated with adjuvant therapy following surgery. Materials and methods. Forty six patients with surgically treated oral tongue cancer were enrolled in the analysis. Adjuvant therapy consisted of postoperative radiotherapy (PO-RT) or postoperative concurrent chemoradiotherapy (PO-CCRT). All patients received three dimensional conformal radiotherapy. Weekly cisplatin was given as concurrent chemotherapy. Identification of prognostic factors for survival was done with univariate analysis. Multivariate analysis was used for factors confirmed as significant on univariate analysis. Results. Independent prognostic factors negatively influencing LRFS, DFS, and OS were ECOG performance status (p = 0.002, p = 0.013 and p = 0.022, respectively), overall stage (p = 0.011, p = 0.010 and p = 0.009, respectively), and pathologic nodal classification (p = 0.016, p = 0.011 and p = 0.015, respectively). Surgical margin status was an independent prognostic factor for RRFS, DFS, and OS (p = 0.032, p = 0.027 and p = 0.028, respectively). The type of adjuvant treatment used was independently prognostic for lower rates of LRFS and DFS (p = 0.029 and p = 0.010, respectively).Conclusions. Positive postoperative nodal status and close or positive resection margins had the most prominent negative prognostic influence on patients’ survival.  
Contribution/ Originality
This study is one of very few studies which have investigated potential prognostic factors that might influence treatment outcome exclusively in patients with squamous cell carcinoma originating from the oral tongue whose adjuvant therapy following surgery consisted of postoperative radiotherapy or postoperative concurrent chemoradiotherapy.

Abstract
This paper is situated within the growing literature on globalization and environment issues as a vital sector in international security. Using a game theoretic approach, it makes hypothetical assumptions on how the impact of globalization on the environment will lead to future security problems in two dimensions- horizontal and vertical. It presents the threat of cross- border pollution between nations sharing geographical boundaries (horizontal dimension) and between developed and developing nations (vertical dimension) as a result of environmental scarcity.
Contribution/ Originality
The paper contributes the first logical assumptions on how the environmental impact of the economic agents of globalization will become an issue in future international security.

Abstract
Fish is a protein source of high nourishing value consumed in the entire world. In Saharan countries it is consumed fresh, however as dried or smoked. However, fish is subject to both fungal and mycotoxins contamination. This study aims to identify fungal presumed producing mycotoxin and to evaluate the contamination level of aflatoxins B1, B2, and G2. A total of 150 samples of dried and smoked fish (Clarias sp. and Oreochromis sp.) have been collected in different islands of the Fitri lake. Standard methods of microbiology have been used for fungal isolation and identification. Aflatoxins content in fish has been determined using HPLC associate to GCMS. Fifty samples (50) were contaminated by four major fungal kinds. Frequency of fungal was to 40 % (Aspergillus niger), 26 % (Aspergillus fumigatus), 20 % (Mucor sp), 8% (Curvularia spp) and 6% (Scycadium). Twenty (20) samples suspected to be contaminated and analyzed, only seven (7) was contaminated with aflatoxins (B1, B2 and G2). The aflatoxin contamination level vary according to the fish species. Clarias sp. samples are 50 % contaminated by aflatoxins when Oreochromis sp are 20 % contaminated. Aflatoxins rates ranged from 0.01 to 2.78 and 0.09 to 0.32 µg/Kg respectively for aflatoxin B1 and aflatoxin B2 for Clarias sp and from 0 to 0.4 µg/Kg of aflatoxin B2 for Oreochromis sp. The mycotoxins level is in average high than the European Union recommendation for dried product. These results call for more sensitization and training for producer for safe dried and smoked fish.
Contribution/ Originality
This study is one of the very few studies which have investigated the contamination level of aflatoxins B1, B2, and G2 in dried and smoked fishes (Clarias sp and Oreochromis sp.) from Fitri lake in Chad.

Government Borrowing Behaviour: Implications for Private Sector Growth in Nigeria

Research Article

Journal: International Journal of Sustainable Development & World Policy

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This study seeks to examine the relationship between government borrowing behaviour and private sector growth in Nigeria. It utilises the Structural Vector Auto-regressions (SVAR) model to analyse the dynamics of government borrowing behaviour on the growth of private sector in Nigeria. The results from impulse response functions and variance decomposition appear to provide evidence that government borrowing behaviour has the tendency of impacting negatively on the effectiveness of private sector grow in Nigeria. This result can be explained, based on the fact that government has higher capacity to borrow than the private sector and this tends to crowd-out private sector in mobilising funds for investment and thus impacted negatively on their capacity to grow. The study, therefore, recommends that both fiscal and monetary authorities should improve on measures and policies that could enhance private sector growth, as higher government debt could create burden for future generations, disrupt movements in interest and exchange rates as well as hinder private investment. Doing this has the potentials of improving performance of private sector and the aggregate economy in Nigeria, since empirical literature is replete with evidence of existence of these channels.
Contribution/ Originality
This study improves on the existing literature by examining the channels and extent of the impact of government borrowing behaviour on the private sector growth in Nigeria, as previous literature has shown varying and often conflicting results due to diversity in the structure of the economy and governance. The study, therefore, confronts the existing theories with recent data and tailor-made methodology.

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This work was able to integrate Internet of Things expertise on Principal Count Analysis (PCA) algorithm for facial recognition optimization. An internet-based real-time facial recognition system was developed using PCA algorithm that can detect and track faces, a label name that indicates the face identified was also incorporated to easily track the face in situations where multiple faces are identified at the same time. A router was used to set up a wireless connection with an internet protocol (IP)-camera via the IP-camera firmware. As the router broadcast this connection, a link is set up with a personal computer through the network and sharing centre tab on the computer system, thereby creating a wireless connection between the computer and the camera on the internet. Graphical interface designed on MATLAB was used to access the feed from the camera which PCA algorithm explored in detecting and tracking faces in real-time. Security features such as timestamp and database were also integrated with the system developed.
Contribution/ Originality
This study integrates PCA algorithm to detect, recognize and match faces detected with a GUI design on MATLAB in real-time. Most importantly a label was created to easily identify the face when multiple faces are detected concurrently.

Abstract
A chatbot system enables communication between computer and users through natural language. The university students face many problems for the queries and details regarding their examination and it is also difficult for them to physically visit the examination department frequently. The concerned authorities find it challenging to handle thousands of student queries in parallel, thus, consuming a lot of time. At present, majority of the chatbot system are available in English language. Therefore, people who are not fluent in English language cannot use these systems due to the obvious reason of language barrier. This paper focuses on the viability of a chatbot system for the examination department of Mehran University of Engineering Technology (MUET) Jamshoro. The chatbot discussed in this paper has been designed to support both Urdu and English languages. Three chatbot interfaces have been developed, Urdu typing based chatbot, English typing based chatbot and English voice based Chabot. The typing based chatbots (both English and Urdu) have been developed using AIML, and voice based chatbot is based on dialogflow called as API.ai. This study is not only concerned with the development of three interfaces of chatbot systems, but also covers their evaluation. To find best chatbot interface, a survey was conducted with engineering students of MUET Jamshoro. The results revealed that the among the three chatbot interfaces, English typing-based interface is the best due to the usability, easiness and the general understanding of queries.

Abstract
Studies on Life tables of Spodoptera litura, were carried out on bidi tobacco cv ABD-101 under laboratory condition at 26 ± 1 °C temperature at Bidi Tobacco Research Station, Anand Agricultural University, Anand (Gujarat). The results on number of individuals survived during development revealed that there was no mortality during egg stage and the maximum durations of egg, larva and pupa were 4, 22 and 14 days, respectively. The number that survived from 100 eggs to adult emergence was 76. The pre-oviposition period was ranged from 41 to 42 days of pivotal age. Females contributed highest number of progeny (mx = 328.12) in the life cycle on the 45th day of pivotal age. The net reproductive potential (Ro) was 758.93 females with the mean length of generation period (T) of 45.67 days. The innate capacity for increase (rm) and finite rate of increase () were found to be 0.1462 and 1.1574 females/ female/ day, respectively with a weekly multiplication rate (λ)7 of 2.78 times. The hypothetical F2 females were found to be 575974.70. Results on per cent contribution of different growth stages in stable age distribution revealed that the egg stage contributed was maximum (52.64%), while the contribution of larvae, pupae and adults were 45.86, 1.36 and 0.12, respectively at stable age distribution of S. litura on tobacco cv. ABD-101.
