ASSOCIATION OF NATURAL FORMALDEHYDE LEVEL WITH QUALITY ATTRIBUTES OF SELECTED SEA FISH, COLLECTED FROM SOUTHEAST COAST OF BANGLADESH
Hossain M.A., Haque M.M, Zim A.F.M.I.U, Aziz M.A, Sharmin K.N.

Abstract: Fishes are a rich source of proteins, vitamins, minerals as well as essential fatty acids but highly perishable because of their high water activity, neutral pH, and presence of autolytic enzymes in their muscles. Recent time in Bangladesh fish vendors is fined by law-enforcement authorities due to the presence of formaldehyde though they donot add additional formalin in their fishes. On the other hand, some fishmongers use chemicals i.e., formalin to extend the longer shelf-life without considering public health issues, at the same time some extent of formaldehyde also produce naturally in fish muscle during the postharvest period. This study aimed to determine the natural formaldehyde level and quality attributes of six sea fish at different time interims. Results revealed that formaldehyde levels were initially raised significantly and then declined in fish muscles with elapsing of time. This study also clarified that fish muscle that produced a higher amount of natural formaldehyde possessed a longer shelf life while lower the microbial load and pH. So it can be concluded that without using external formalin, fish vendors can preserve their fishes on around six to eight hours.

P.H.Wijenayake, M.S.N Manathunga, Y. J.Samarasinghe, I.W.M J Wickramarathne, A.J Abeynayake, R.G.K.Vijayakumara

Abstract: Patient safety is a major concern for all health care providers worldwide. For creating patient safety culture the attitudes, values and beliefs of the members of the health care institutions towards patient safety should be improved. The study is expected to assess the culture of patient safety at Teaching Hospital Mahamodara - Galle (THM) and, Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire was used as the study instrument. The responsibility of creating a culture of safety belongs to all employees in a hospital; however, It will be successful only the involvement of senior management. In order to understand where to focus efforts in building this environment, hospital senior management must understand the opinions and beliefs of the employees regarding the safety culture of their hospital, before initiating a health and safety program.

A Mathematical Model for the Control of the Spread of Meningitis Virus Disease in West Africa- A Disease Free Equilibrium and Local Stability Analysis Approach
Egahi M., Agbata B.C., Shior M.M.,Odo C. E.

Abstract: In this research work, we developed and analysed a deterministic model for controlling the spread of meningitis virus disease in a population using disease free equilibrium and local stability analysis approach. The entire population was partitioned into six compartments which are: susceptible (S), vaccinated individuals (V), Carriers (C), infected individuals (I), treated individuals (T) and recovered individual (R) and every newborn in each compartment is previously infection free by assumption. A mathematical analysis of disease free equilibrium, basic reproduction number and local stability analysis were carried out. The results show that the disease free equilibrium state is stable and the endemic equilibrium state is locally asymptotically stable.

Addressing the Voice of Women in Marine and Maritime Industry
Ahalya Arulnayagam

Abstract: Marine and maritime industry often have been acknowledged as male-dominated. Women represent nearly 2% of the workforce in the maritime community. Even though, the marine and maritime industry have been evolving throughout history, women’s placement in it has not been notorious. Women are seldom neglected from the global industry for being family-committed and/ or being considered as weaker sex. Yet women play major roles in sustainable development hence they should be incorporated in ocean-based policy, governance and decision-making. Lower wages, gender disparity, discrimination on board, and harassment can encourage women to keep themselves away from the ocean. Institutions are trying to provide a fair recognition of women in the ocean-related jobs but still efforts are required. It is vital to reduce gender disparity in marine professions and to promote the involvement on women in ocean related diligences. Consistent efforts are required to seize the moment for acknowledgement, in terms of encouragement and support for closing the gender gap This paper aims to elaborate the concerns of gender equality in marine and maritime industry.

Comparative expression of adhesion protein N-cadherin in oral lichen planus versus other precancerous and cancerous oral conditions
Heba A. Elhendawy, Doaa AM Esmaeil, Doaa Abdallah Farag

Abstract: Oral Lichen planus (OLP) is a common chronic mucocutaneous disorder with an immune mediated pathogenesis. It is a complex and poorly understood clinical condition with periods of remissions and exacerbations. The risk of malignant transformation of OLP is still a controversial topic. The current study aimed to investigate the role of N-cadherin in OLP by comparing its expression with premalignant oral diseases, oral squamous cell carcinomas and normal oral epithelium. 17 cases of premalignant conditions (oral submucous fibrosis, proliferative verrucous leukoplakia and leukoplakia with dysplasia), 15 cases of erosive ulcerative OLP, 15 cases of OSCC (5 cases from each histologic grade) and 5 cases of normal oral mucosa all were analyzed immunohistochemically for N-cadherin expression. N-cadherin was positively expressed in 47 cases (90.4%) and negative in 5 cases (9.6%). All the studied OSCCs and premalignant lesions demonstrated positive expression. A high statistically significant difference in N-cadherin expression among the studied different OSSC histological grades (P=0.000), OLP and OSCCs (p=0.008), OSCCs and normal oral mucosa (p= 0.000), premalignant lesions and normal oral mucosa (p=0.002). Furthermore, no statistically significant difference between OSCCs and premalignant lesions (p=0.107). Conclusion: N-cadherin can differentiate between behavior of OLP, premalignant lesions and OSCCs.

A Study on Mouse Movement Features to Identify User
Masud Karim , Md. Hasanuzzaman

Abstract: Identifying real user is a vital issue in information security. Various processes are using to identify user like password, punch card, PIN etc which identify some characters of a user but not the real user. Biometric identification techniques can identify real user like face decoction, finger print, iris technology etc but these are cost effective and not user friendly due to requirements of extra devices and systems. For this reason, researchers are giving emphasis on mouse movement based user identification technique. This technique solves current problems of real user identification and need no extra device. In this technique features are generated from mouse movement data and based on these features users are identified. Different researchers are proposing different types of features for identifying user from mouse movement data. Selecting and calculating these features is very important issue for this technique. In this paper we have shown such features collectively those are using by different researchers. We have tried to categorized and describe such features in different types with accuracy. Recommendation is mentioned in this paper for further using of mouse movement features.

Production, Purification and Characterisation of Keratinases From Bacillus species Isolated From Poultry Feather Waste
Michael Dada, Sherifah Wakil

Abstract: Feather is high in protein (keratin) and is not easily degradable in nature. It is produced in large amounts as waste through poultry activities all over the world. In order to provide sufficient use for this keratin-rich waste the keratin present in feather can serve as keratinase inducer. Hence this study focuses on the production, purification and characterisation of keratinases from isolated keratin-degrading Bacillus licheniformis-K51, Bacillus subtilis-K50 and Bacillus sp.-K53. Bacillus licheniformis-K51 gave highest keratinolytic activity (24.76±0.91 U/mL) at pH 7.8, 37 oC, agitation rate 150 rpm and 0.3% (NH4)2SO4 on day 7, while Bacillus subtilis-K50 had 19.03±0.74 U/mL at pH 7.5, 37 oC, agitation rate 200 rpm and 1.4% cellulose on day 4. Bacillus sp.-K53 gave least activity (18.41±0.60 U/mL) at pH 7.2, 37 oC and agitation rate 150 rpm on day 5. Molecular mass of purified keratinases was determined using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis and was obtained between 33-36 kDa. Purified enzyme of Bacillus licheniformis-K51 (EZYKer-51) contained Glutamate (18.2%), Alanine (14.9%) and showed highest activity (26.31 U/mL) at 60 oC and pH 8 with KM and Vmax kinetic constants of 25.60 mM and 74.46 U/mL, respectively.

Knowledge, Awareness and Perception of National Gas Policy (NGP) 2017 among Oil and Gas Legal Experts in Nigeria
Dr Temilade O. Jolaosho

Abstract: Knowledge and experience are intrinsically connected. Studies have generally shown that knowledge, aw-areness and perceptions are directly proportional to the skills and experience of individuals in their respective disciplines. Propped on the theory of epistemology, this study was aimed at assessing the knowledge, awareness and perceptions of the oil and gas legal experts on the National Gas Policy (NGP) 2017. The knowledge assessment was carried out by compari-ng the correlation between academic qualification and years of experience of the experts on the Nigerian policy framework of the gas sector (with emphasis on the NGP 2017). The study highlights the attempts of the present policy framework at reducing gas flaring. Furthermore, the study found that there is no significant relationship between the years of experience and the knowledge of oil and gas experts on the NGP 2017,as some with less years of experience were found to be more kno-wledgeable about the policy. The existing gap in knowledge could be attributed to the absence of an in-depth knowledge of the oil and gas legal experts on some aspects of NGP 2017. The study therefore suggests a possible inclusion of advanced education on market based instruments in environmental law curriculum subsequently.

IMPACT OF SMALL SCALE MINING ON RURAL LIVELIHOODS IN SOME PARTS OF YAURI AND FAKAI LOCAL GOVERNMENT AREAS OF KEBBI STATE, NIGERIA
Abubukar, M. Y.; Zankan, J. A. A and Isah, M. N.

Abstract: Small scale mining is an important livelihood activity to most rural dwellers living in communities endowed with mineral resources. This study examined the impact of small scale mining on rural livelihoods in some parts of Fakai and Yauri local government areas of Kebbi State, Nigeria. Data for this study was collected through direct field observation and focus group discussion (FGD). Six different sessions of FGD of eight participants was conducted which were purposely selected based on their participation and knowledge in mining. The results of the study indicated that the mining activities is undertaken by individuals and groups who rely heavily on manual labour, using simple implements such as chisel, hammer, digger and shovel. The constraints to mineral exploitation include rock falls and subsidence, drug abuse and addiction, use of crude equipments, exposure to dust/health risk, and security challenges. The findings also revealed the following as the benefits of small scale mining in the study area: source of income generation, it creates employment to people, improves crop farming and livestock production, and improves petty trading and blacksmithing. It is therefore recommended that miners should suspend mining activities during the rainy season in other to avoid subsidence or rock falls and revisit their farmlands for agriculture. They should be educated on the dangers of drug abuse and also advice to eat nutritious and palatable food to maintain healthy living. Finally, they should sponsor their children to study so as to reduce their suffering from mining.
