Abstract:Small and medium enterprises (SMEs) have been identified as catalysts for the economic growth in Nigeria as they are major sources of income generation and job creation and contribute immensely to the nation’s gross domestic product (GDP) as well as livelihood sustainability in the country. Despite what private investors and government have done and still doing in order to enhance the performance of the SMEs, most of them are still constrained by poor management skills and lack of modern technology, which may be as a result of inadequate financing leading to inadequate sales growth. The general objective of the study was to determine the effects of entrepreneurial financing dimensions on the sales growth of selected SMEs in Ogun State, Nigeria. The study adopted cross-sectional survey research design. The population comprised 1,794 owner/managers of SMEs. The sample size was 425. A validated questionnaire was administered for data collection. The Average Variance Extracted of the constructs ranged from 0.741 to 0.908. The response rate was 82.4%. Data were analysed using descriptive and inferential statistics and multiple regressions. Findings from the study revealed that eentrepreneurial financing dimensions (bank loans, government grant, venture capital, funds from family) had positive and significant effect on sales growth of SMEs in Ogun State (R = 0.601, Adj. R2 = 0.354, F (4, 345) = 48.764, p < 0.05). The study concluded that entrepreneurial financing dimensions play an important role in enhancing the performance of selected SMEs in Ogun State, Nigeria. Thus, this study recommended that the financial institutions should creatively craft and adopt the availability of cheaper funds that would spur the sales growth of SMEs with view to sustainability while enhancing economic growth.
Abstract:Price stickiness affects economic system broadly. This article focuses onduopoly innovation under sticky price with differential game theory approaches. Wefound that sticky price weakens firmsï¿½ market power and stimulates firmsï¿½ innovationunder both open-loop and closed-loop solution. Moreover, higher price stickinessyields more outputs and lower price. More interestingly, open-loop equilibriumstimulates innovation more than that of closed-loop. The policy implication is toencourage commitment price strategy.

Abstract:Forensic entomology is considered a branch of general entomology which was recently founded and ruled by the Entomology Society of America in the 1990s, followed by this ruling the society approval came to establish what is known today as the American Board of Forensic Entomology (ABFE) in 1996. \nIt can be also called forensic biology which is the field of science that depends on different kinds of insects as a fundamental base to reveal the mystery of a crime circumstances especially violence crimes in general and homicides in specific. As many insects start their life cycle when the death of a living creature occurs, criminology have used many ways to reveal the mystery of a crime facts and circumstances, but even with the great scientific evolution a medical examiner is still unable to estimate the exact precise time of death after the passage of 72 hours corpse decomposition, however by using forensic entomology the exact time of death can be precisely estimated. \nIt is for sure that forensic science depends on more than field of science and method to solve and reveal the mysteries of crimes, and for every case there is a way or more that can be more analytically accurate for an incident, and sometimes more than one method are used for the same crime to reveal the identity of a murderer or the time of death in a more positively accurate way. \nConsequently insects are used in forensic science in combination with other critical important fields of science in criminal investigation like criminological psychology, Toxicology, Forensic Identification, fingerprint, hair print and memory print identification, and most importantly the DNA profiling.
Abstract:Regarding the disposal of agricultural wastes (such as pig manure and urine), three-stage or batch-type wastewater treatment is mostly adopted in Taiwan. The sludge produced is then used to synthesize organic fertilizers through biological technology, or to make engineering fillers for reuse directly through physical treatment. In fact, agricultural waste can generate biomass energy (such as biogas) through the principles of anaerobic digestion. Among them, the electro-fermentation technology has been proposed in recent years and has aroused widespread discussion. The concept of electro-fermentation technology uses electrochemical principles to drive microorganisms to carry out fermentation reactions, and it has been proven in the laboratory for effectively producing biogas. This biogas production even surpasses traditional anaerobic digestion systems. In addition to effectively reducing the organic content of agricultural waste, electro-fermentation technology can also convert it into value-added biomass products (such as organic acids), adequately taking into account the both environmental protection and realization of circular economy concepts. In view of this, this article systematically reviews the principles and performance of electro-fermentation technology, including reactor design, product types and practical applications, and at end proposes opportunities and prospects for applying electro-fermentation technology in the future.
Abstract:Cement is the most widely used building material and construction activities could not possible without it. The cement industry facing the depletion in natural resources and global greenhouse gas emissions (carbon dioxide emissions) related issues. For sustainable development, striving for the reduction in carbon dioxide emissions and constraints on natural resources cause the necessitate requirement of sustainable alternatives as substitutes of traditional raw materials. Therefore, a current study has been carried out to use sewage sludge (locally available waste material) and carbide lime sludge (CLS) in construction as recycled fines (RF) which are obtained from sewage sludge in the form of ash (SSA) after its incineration and CLS as a byproduct of acetylene industry respectively. The effects of partial replacement of OPC using RF on compressive strength and split tensile strength after the 3rd, 7th and 28th day have been evaluated. The outcome from the study shows that the elevating replacements of RF up to 70% can be used in mortar as per IS: 2250 (2000) in structural applications. Utilization of RF up to 70% would be possible with OPC as it indicates an acceptable level of compressive strength of mortar, conservation of depleting natural reserves, saving in thermal and electrical energy besides emissions reduction of carbon dioxide.
Abstract:Genetic Algorithm (GA) has been found successful in implementing the solution of a significant number of optimization tasks associated with machine learning, computer vision, pattern recognition, knowledge discovery and so on due to its robust global search strategy. This article explores the development of a robust framework on selecting features in urban land cover analysis for high resolution images using GA. The approach is focused on object based classification by detecting the object area in a given image with the help of visual information of the object from remote sensing images. The classification scheme has been organized with a multilayer perceptron (MLP) with back propagation algorithm. Experimental results reveal that this MLPGA based hybrid feature selection approach achieves better than the relevant counterpart approaches considering classification accuracy.
Abstract:Escherichia coli is a commensal bacteria in the digestive tract of animals that is very influential on health. There has been a lot of research on Escherichia coli, but no studies have addressed the idea of publishing Escherichia coli in Veterinary Medicine which shows the big overview using data from all countries. This study aims to map the status of Escherichia coli publications in Veterinary Medicine which are published internationally and indexed by Scopus using bibliometric visualization. Bibliometric methods and research data analysis were implemented using analysis search results services from Scopus and VOSviewer applications. In this study, the details collected apply to 5836 documents published from 2011 to 2020. Research reveals that Kim, I.

There are six maps of collaborative research groups in Escherichia coli publications in Veterinary Medicine around the world. To identify a body of knowledge created from ten years of publication, this study builds a convergence axis grouping consisting of Escherichia coli studies: Immunology, Virulence Factors, Microbiology and Molecular Examination, and Animal abbreviated with the theme IVMA.
Abstract:The purpose of this study was to detect and compare the incidence rates of Methicillin Resistant Staphylococcus aureus (MRSA) with Methicillin Resistant - coagulase negative staphylococci (MR-CNS) that contaminated the milk of dairy cows in East Java. A total of 220 cow\'s milk samples were collected from at 4 dairy farms in East Java Province, then followed by isolation and identification of S. aureus and CNS by standar laboratory methods. The Methicillin Resistant test was carried out on Mueller Hinton Agar (MHA) by the Kirby Bauer disc diffusion Cefoxitin 30 μg and Oxacillin 30 μg preparations, then confirmed with the Oxacillin Resistance Screen Agar Base (ORSAB). The results showed that there were 114 S. aureus with confirmed MRSA strains of 30 isolates and 106 CNS with confirmed MR-CNS strains of 12 isolates. It was concluded that the raw milk from dairy farms can be a potential reservoir for spreading of MRSA strains and MR-CNS strains to threat public health.
Abstract:This paper deals with pulsed mode laser beam welding (LBW) on 2 mm thick Ti-6Al-4V alloy sheets. ANSYS Fluent 16.0 version is utilized to develop a generic model with Vc++ code. The model is validated with test results. The optimal LBW parameters are obtained by maximizing the depth of penetration (DP) and minimizing the weld bead width (BW). To minimise the number of numerical simulations, Taguchi approach is adopted. The LBW parameters considered are pulse frequency, pulse width and welding speed,the absorbed power is kept as constant. The performance indicators are width of fusion zone, depth of penetration, heat affected zone and maximum temperature. The optimal LBW parameters are found to be dependent onthe process indicators. A simple reliable modified Taguchi approach is followed to get a set of optimal LBW parameters for maximum DP and minimum BW.
