Abstract: Se llevó a cabo un estudio en todo el estado de Jigawa en la república de Nigeria durante noviembre-diciembre, parte de la estación de seca; donde la malaria es una de las principales causas de morbilidad y mortalidad, especialmente entre los ni os menores de 5 a os y las mujeres embarazadas. Este estado presenta 2 estaciones climáticas una seca de octubre a mayo y otra de lluvia de junio a septiembre. Se muestreó un total de 112 cuerpos de agua, solo 18 en 9 gobiernos locales resultaron positivos a mosquitos. Los sitios de cría identificados para Anopheles correspondieron a campos de arroz, peque o hueco en la tierra, pisadas de animales, peque os estanques, terrenos con pasto inundados y presa de tratamiento de agua, para un total de 10. Contrario a lo que siempre se ha reportado sobre la presencia de Anopheles en aguas limpias, se encontraron criando en aguas con alta polución que contenían heces fecales humanas y desperdicios de basura, representadas por alcantarillas abiertas en las localidades. A study was conducted in the state of Jigawa, Republic of Nigeria, from November to December in the dry season, where malaria is one of the main morbidity and mortality causes particularly in under 5 years-old children and pregnant women. This state had two climate seasons: dry from October to May and rainy from June to September. A total of 112 water bodies were sampled and just 18 in nine local governments were positive to mosquitoes. Breeding sites for Anopheles were rice fields, small holes in land, animal footsteps, small ponds, flooded pasture fields and water treatment dam, among others, to amount to 10 sites. Contrary to what has always been reported about the presence of Anopheles in clean waters, they were also breeding in highly polluted waters containing human faeces and garbage and located in open sewers. Key words: Breeding sites, Anopheles, malaria, Nigeria.

Effect of Locally Prepared Compounds on The Resistance of Gum Arabic Wood to Termite Attack
Alkali, U. U.,Muktar, A.
Journal of Environmental Issues and Agriculture in Developing Countries , 2011,
Abstract: The effect of three locally prepared compounds (table salt,potash and tamarind leave extract) and their combinations as preservatives of gum Arabic tree (Acacia senegal) wood against attack by termites was investigated in a 12-week experiment in Yobe State of Nigeria. One hundred and ninety two (192) wood samples of same dimensions were cut from branches of freely growing gum Arabic trees. The samples were carefully debarked to avoid scaring the wood, rinsed in clean water and oven-dried at 105 ± 3oc until constant weight was achieved. The samples were then weighed and measured for length and diameter and then exposed to three termite mounds of similar size housing the same subterranean termite species (Macrotermes bellicosus) for 12 weeks at 3 different locations using a randomised complete block design. At the end of the 12th week, they were removed, rinsed and oven-dried, weighed and inspected for possible damage. Treated wood samples were heavier, longer and had bigger diameters than the untreated control. Location had no significant effect on the extent of termite attack. It was concluded that the compounds in test could have either toxic, repellent or both effects on the insect, thus suggesting that the compounds have high potential as wood preservatives.

Nigerian Journal of Surgical Research , 2005,
Abstract: Background: Hepatitis B infection has long been known to be common in the general population and due to its mode of transmission through blood transfusion; it had made provision of safe blood difficult especially in developing countries. Method: A retrospective study aimed at reassessing the current of sero-prevalence of hepatitis B infection in blood donors in a typical developing country was conducted. Results: Six thousand and twenty five regular blood were screened our of which 254 (4.2%) were HBsAg positive with lowest rates being in 2001 (3.5%) and the highest rates occurred in 2002(5.1%).Age of donors ranged from 19-42years with a mean 33 years, 98% were males while only 2% were females. Prevalence of HBsAg was 47.2% in patients' replacement donors, 44.5% in relations of antenatal clinic attendees and 8.3% in voluntary donors. Conclusions: This study has revealed a high prevalence rate of hepatitis B infections in all age groups and categories of blood donors in our setting which makes transfusion of unscreened hazardous.

Hepatitis C virus infection in blood donors: An emerging risk to transfusion services
Muktar H,Jones M,Ashie J
Annals of African Medicine , 2006,
Abstract: Background : Hepatitis C infection is transmissible via transfusion of blood and blood products. Little work exists in local literature on its prevalence. Methods : A prospective study aimed at documenting the sero -prevalence of hepatitis C virus infection in blood donors in a tropical environment. Results : A total of four thousand six hundred and thirty three regular blood donors were screened over a 3 year period. Age of donors ranged between 19 and 42 years with a mean of 33 years. Two hundred and forty one donors (5.2%) were seropositive. Age- specific prevalence rates ranged from 0.09% to 1.7%.Yearly prevalence rates ranged from 3.4% to 6.9%. Conclusions :This study shows that the prevalence of HCV infections in our blood donors is high and requires active and sensitive screening in order to improve the safety of banked blood.

ISRN Public Health , 2014, DOI: 10.1155/2014/205074
Abstract: Background. Mobile phones of health professionals can harbor various potential pathogens and become exogenous sources of infection for the patients, self, and family members. This study assessed the frequency and antimicrobial susceptibility pattern of bacteria from mobile phones of health care workers. Methods. In this crosssectional study a total of 58 health care professionals mobile phones were swabbed before and after decontamination with 70% alcohol and assessed for contamination with bacteria. Bacterial isolation, identification, and antimicrobial susceptibility test was done as per the standard procedures. Results. About 98% of the mobile phones assessed in this study were contaminated with bacteria. Coagulase negative Staphylococci, S. aureus, and E. coli were the most frequently isolated bacteria. Decontamination with 70% alcohol significantly decreased the rate of contamination from 98.3% to 55.2% . About 17% of the isolates were resistant to two drugs. Conclusion. Appropriate infection prevention measures should be taken to minimize the risk that could be associated with mobile phones since the rate of contamination was high. Decontamination with 70% alcohol was effective in minimizing bacterial contamination of mobile phones so it should be used as a decontaminant agent for these apparatuses. 1. Introduction Mobile phones have become part of health professional’s equipment and are used extensively for communication in a clinical setting [1]. Innovations in mobile communication have led to better patient control of diabetes and asthma and increased uptake of vaccinations by travelers reminded by short message service (SMS) [2]. However, they are seldom cleaned and are often touched during or after examination of patients and handling of specimens without proper hand washing. These cell phones can harbor various potential pathogens and become exogenous sources of infection for the patients and are also potential health hazard for self and family members [3, 4]. Further, sharing of cell phones between HCWs and non-HCWs may directly facilitate the spread of potentially pathogenic bacteria to the community [5]. Nosocomial infections constitute a major problem globally with major social, economic, moral, and personal effects that increase morbidity and mortality of hospitalized patients [6]. It is estimated that between 5% and 10% of patients admitted to hospitals acquire HAI, but recent data suggest that this figure is on the rise [7]. The extended duration of hospital admission and extra drugs or medical management may contribute to additional

Abstract: Poverty is not something new issue for a country. Poverty is seen as a problem that could negatively impact on a country. Malaysia also cannot escape from this poverty problem. Malaysia is a country where the Moslem people are majority and they are permanent resident. Therefore, from the perspective of Islam, poverty had been seen as a social disease [1]. According to the post’ or scholars’ statement, one of the ways poverty can be overcome is the implementation of the community development program. One of the community development programs in Malaysia that for farmer and house hold that involve in agriculture is called AZAM Tani. A study was conducted on participants AZAM Tani (Agricultural AZAM) areas of Seberang Perai, Penang. AZAM are words in Malay language. It is also short form and stand for End Time of The Poor. The method used was census. A total of 54 respondents were found. The results showed that the AZAM Tani program is able to help increase knowledge. Then with the knowledge that the participants had, they are able to raise their level of skills. This can be seen in the results of Spearman correlation indicating the relevance of knowledge to the implementation of the program and the relevance of relationship knowledge and skills with r = 0.612, p < 0.05. This relationship is positive. The study also shows an increase in the income level of the respondents.
Comparing the Accuracy of Network Utilization Performance between Real Network and Simulation Model for Local Area Network (LAN)  [PDF]
Mohd Nazri ISMAIL, Abdullah Mohd ZIN
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2008, DOI: 10.4236/ijcns.2008.14042
Abstract: This article presents a novel approach for the measurement and estimation of network traffic utilization between network nodes in heterogeneous environment. This research investigates performance evaluation of network interface on heterogeneous services and technologies environment. This study proposes an enhanced equation to evaluate the performance of network interface via Little Law and Queuing theories to improve the evaluation algorithm. To get accuracy results on the performance of simulation model, it measures (verify and validate) data from Local Area Network (real network environment). This project uses network management tool to capture those data and Fluke Optiview device to generate traffic. As a result, this simulation model can provide a good approximation of the real traffic observed in the real network environment. Through laboratory and field experiments, the result shows that the model via simulation is capable of approximating the performance of network utilization and traffic over heterogeneous services and techniques within a minimum error range.
Improved NCTF Control Method for a Two-Mass Rotary Positioning Systems  [PDF]
Mohd Fitri Mohd Yakub, B. A. Aminudin
Intelligent Control and Automation (ICA) , 2011, DOI: 10.4236/ica.2011.24040
Abstract: This paper describes an improvement of the existing nominal characteristic trajectory following (NCTF) as a practical control method for a two-mass rotary point-to-point (PTP) positioning systems. Generally, the NCTF controller consists of a nominal characteristic trajectory (NCT) and a PI compensator. A notch filter is added as a part of the compensator to eliminate the vibration due to the mechanical resonance of the plant. The objective of the NCTF controller is to make the object motion follow the NCT and end at its origin. The NCTF controller is designed based on a simple open-loop experiment of the object. The parameters identification and an exact model of the plant are not necessary for controller design. The performance response of improved NCTF controller is evaluated and discussed based on results of simulation. The effect of the design parameters on the robustness of the NCTF controller to inertia and friction variations is evaluated and compared with conventional PID controller. The results show that the improved NCTF controller has a better positioning performance and is much more robust than the PID controller.
