    . Various efforts to control mosquito-borne diseases have been done i.e the use of insecticide-treated nets (ITN). The aim of this study was to determine the insecticide permethrin in the nets to control Anopheles vagus mosquito that were widely distributed in the village of Tanjung Seleman, Muara Enim district based upon age and frequency of laundering. An experimental research using a complete randomized design was conducted in April-December 2010. Data regarding the effectiveness of permethrin against Anopheles, were collected through biossay test (WHO cone test) with contact method. Entomology bioassay data is the average of mosquito mortality for nets that given in 2006 was 66.5%, for the nets in 2007 the mortality rate reached 67.3%, and for mosquito nets in 2008 the mortality rate reached 67.5%. It shows that there were differences effect on mortality of An. vagus which exposed to mosquito net that has never been washed with the washing 1-3 times or more, while the mortality of mosquito that exposed to different age of nets shows no significantly difference. Percentage of An. vagus mortality that exposed by permethrin insectiside is still high

    Chicken nugget is a processed chicken product, cooked made from a mixture of ground chicken meat were given coating, with or without the addition of other ingredients and permitted food additives. Chicken nuggets are a popular food product, but chicken nugget has the disadvantage that has a low fiber content. Lack of fiber content can be improved by adding menjes flour on chicken nuggets. Menjes flour have a high fiber content, which is 61.55%, has a savory flavor, widely available and affordable price. The design of the study is a randomized block design (RBD) with one factor, seven level of menjes flour concentration of 0%, 1.5%, 3%, 4.5%, 6%, 7.5% and 9 % with three times repeated. Parameter study include WHC, pH, moisture content, fiber content, texture (hardness, springiness, cohesiveness, fractubility, gumminess and chewiness), and product preferences in organoleptic (juiceness, texture and flavor). The data will be analyzed by Analysis of Variance (ANOVA) at α = 5% and further testing is test DMRT (Duncan's Multiple Range Test) at α = 5% when there are significant differences between treatments. The result showed that the difference variation in addition of menjes flour was significantly affected (α = 5%) against moisture, WHC, texture (hardness and cohesiveness). Variation in addition of menjes flour also significantly affected to product organoleptic including flavor, texture, and juiceness. Larger addition of menjes flour increasing moisture content and hardness, but decreasing WHC, cohesiveness and panelist preference. The best treatment was obtained at addition 1.5% menjes flour with 160% WHC, 55.82% moisture content, 9534.204 g hardness, 0.637 cohesiveness, and 2.09% dietary fiber

    Self-Timed Rings: A Promising Solution for Generating High-Speed High Resolution Low-Phase Noise Clocks

    International audienceA high-speed multi-phase oscillator based on self-timed ring is proposed. Self-timed rings (STR) are promising approach for designing high-speed serial links and clock generators. Indeed, the architecture of STR allows us to achieve high frequencies with multiphase outputs and their oscillation frequency is not only depending on the number of stages but also on the initial state of the ring. Moreover, this architecture allows us 3 dB phase noise reduction when, while keeping the same frequency, when the stage number is doubled. In this chapter, we propose a method to design STR able to generate high-speed multi-phase outputs and we suggest a design flow for designing low-phase noise self-timed ring oscillators. A test chip has been designed and fabricated in STMicroelectonics CMOS65nm technology to verify the theoretical claims and validate the simulation results

    BACKGROUND: Ivermectin is used extensively globally for treatment of helminthic and ectoparasitic infections in animals and humans. The effect of excreted ivermectin on non-target organisms in aquatic and terrestrial environments has been increasingly reported. Due to its low water solubility and adsorption to sediments, the ivermectin exposure-risk to aquatic organisms dwelling in different strata of water bodies varies. This study assessed the survival of larvae of Anopheles gambiae Giles and Culex quinquefasciatus Say, when exposed to low concentrations of ivermectin under laboratory conditions. METHODS: A total of 1800 laboratory reared mosquito larvae of each species were used in the bioassays. Twelve replicates were performed, each testing 6 concentrations of ivermectin (0.0, 0.001, 0.01, 0.1, 1.0 and 10.0 parts per million (ppm)) against third instar larvae of An. gambiae and Cx. quinquefasciatus. Larval mortality was recorded at 24 and 48 h post addition of ivermectin. RESULTS: Survival declined markedly with increase in ivermectin concentration in both species. While mean survival of An. gambiae at 24 h of exposure was 99.6 %, 99.2 % and 61.6 % in 0.001, 0.01 and 0.1 ppm of ivermectin, respectively, the mean survival of Cx. quinquefasciatus at the same dosage and time was 89.2 %, 47.2 % and 0.0 %. A similar pattern, but with higher mortality, was observed after 48 h of exposure. Comparison between the species revealed that Cx. quinquefasciatus larvae were significantly more affected by ivermectin than those of An. gambiae, both at 24 and 48 h. CONCLUSIONS: Low concentrations of ivermectin in the aquatic environment reduced the survival of larvae of An. gambiae and Cx. quinquefasciatus, with the effect being more marked in the latter species. It is suggested that this difference may be due to the different water strata occupied by the two species, with ivermectin adsorbed in food that sediment being more readily available to the bottom feeding Cx. quinquefasciatus than the surface feeding An. gambiae larvae
