Minimizing localization error and ensure security of DVHOP using random key approach

Communication through the mobile network is need of the hour. Thus localization becomes important issue discussed in this paper. Algorithms are many which can be range free and range based. The DVHOP algorithm with random key is used to solve the localization problem. The localization is required since node when on the go will require to disseminate data then position determinism is paramount which is achieved with the help of localization. Distance could be of any range when mobile nodes are considered hence range free algorithm is considered. Security aspect of the data is paramount. Since node capture attack is common. Ways to detect and prevent the attack in terms of Random key is suggested. The result obtained will be in terms of the localization error which is given both in terms of localization with and without Node capture attack and random key

Thermal energy harvesting of highly conductive graphene‑enhanced parain phase change material

Solar energy is the most plentiful renewable energy source that has the capability to keep up with the growing demand. When the sun’s energy is not available, thermal energy storage (TES) using phase change material (PCM) is a promising technique for storage and utilization. However, PCM’s low thermal conductivity may limit its use. The use of nanomaterials to enhance the thermal conductivity is one of the prominent solutions to overcome this issue. This research work reports that graphene nanoparticles (0.1%, 0.3%, 0.5%, 0.7% and 1% mass) enhanced paraffin wax (PW) to improve the thermophysical properties and transmittance capability. Thermogravimetric analyzer (TGA), differential scanning calorimeter (DSC), Fourier transform infrared spectroscopy (FTIR) and ultra-violet visible spectroscope (UV–VIS) were used for the characterization of the base PCM and nano-enhanced phase change materials (NePCM) composites. A significant improvement of 110% in thermal conductivity was obtained at 0.7% mass ratio compared to base PW without compromising the prepared composites’ latent heat storage (LHS) capacity. TGA and FTIR outcomes demonstrated excellent thermal and chemical stability, respectively. To check the thermal reliability of composite, the PW and nanocomposite were subjected to repeated thermal cycling. The outcome evidence that the NePCM composite had consistent thermal energy storage properties even after repeated thermal cycles. The composite’s light transmission was drastically lowered by 56.34% (PW/Gr-0.5) compared to base PW, resulting in PW/Gr composite has better thermal reliability in relation to thermal conductivity and LHS than base PCM, which can be used specifically in photovoltaic thermal systems and TES

Review Article Socio-economic determinants of micronutrient intake and status in Europe: a systematic review

Objective To provide the evidence base for targeted nutrition policies to reduce the risk of micronutrient/diet-related diseases among disadvantaged populations in Europe, by focusing on: folate, vitamin B-12, Fe, Zn and iodine for intake and status; and vitamin C, vitamin D, Ca, Se and Cu for intake. Design MEDLINE and Embase databases were searched to collect original studies that: (i) were published from 1990 to 2011; (ii) involved gt 100 subjects; (iii) had assessed dietary intake at the individual level; and/or (iv) included best practice biomarkers reflecting micronutrient status. We estimated relative differences in mean micronutrient intake and/or status between the lowest and highest socio-economic groups to: (i) evaluate variation in intake and status between socio-economic groups; and (ii) report on data availability. Setting Europe. Subjects Children, adults and elderly. Results Data from eighteen publications originating primarily from Western Europe showed that there is a positive association between indicators of socio-economic status and micronutrient intake and/or status. The largest differences were observed for intake of vitamin C in eleven out of twelve studies (5-47 %) and for vitamin D in total of four studies (4-31 %). Conclusions The positive association observed between micronutrient intake and socio-economic status should complement existing evidence on socio-economic inequalities in diet-related diseases among disadvantaged populations in Europe. These findings could provide clues for further research and have implications for public health policy aimed at improving the intake of micronutrients and diet-related diseases

Resistance Status of the Malaria Vector Mosquitoes, Anopheles stephensi and Anopheles subpictus Towards Adulticides and Larvicides in Arid and Semi-Arid Areas of India

Susceptibility studies of malaria vectors Anopheles stephensi Liston (Diptera: Culicidae) and An. subpictus Grassi collected during 2004–2007 from various locations of Arid and Semi-Arid Zone of India were conducted by adulticide bioassay of DDT, malathion, deltamethrin and larvicide bioassay of fenthion, temephos, chlorpyriphos and malathion using diagnostic doses. Both species from all locations exhibited variable resistance to DDT and malathion from majority of location. Adults of both the species were susceptible to Deltamethrin. Larvae of both the Anopheline species showed some evidence of resistance to chlorpyriphos followed by fenthion whereas susceptible to temephos and malathion

Kumaoni and Garhwali of Uttarakhand hills, and Rohilkhandi of upper Ganges alluvial plain of Uttar Pradesh (India) were characterized phenotypically with standard morphometric parameters. The animals were also evaluated for their reproductive and production performance. The null hypothesis that Garhwali, Kumaoni and Rohilkhandi goat populations are same was tested using value of discriminant functions (D), Wilks’ Lambda and Box’s M statistics. The classification results revealed that 84.9% of all the goats were correctly classified to their own population. This could be used by livestock development agencies to take up appropriate breeding program for the improvement of native stock for future genetic conservation. The milk composition of Uttarakhand goats did not differ much due to geographic identities except for milk fat percentage. The study revealed that body height, body length, horn pattern, face length, and chest girth were the most discriminating and unique variables to separate Rohilkhandi, Kumaoni and Garhwali goat populationsNot Availabl

Non-digestible oligosaccharides modulate intestinal immune activation and suppress cow's milk allergic symptoms

BACKGROUND: Cow's milk allergy is a common food allergy in childhood and no effective preventive or curative treatment is available. This study aimed at comparing single short-chain galacto- (scGOS), long-chain fructo- (lcFOS) or pectin-derived acidic oligosaccharides (pAOS) and/or mixtures of scGOS/lcFOS (GF) or scGOS/lcFOS/pAOS (GFA) to prevent or treat food allergy. METHODS: In the preventive protocol, C3H/HeOuJ mice were fed diets containing single oligosaccharides or mixtures GF or GFA throughout the study protocol. In the treatment protocol, GF or GFA was provided for 4 wk starting after the last sensitization. The allergic skin response and anaphylaxis scores were determined, after oral challenge whey-specific immunoglobulins were measured, and qPCR for T-cell markers and Foxp3 counts using immunohistochemistry were performed on the small intestine and colon. RESULTS: Only in the preventive setting, the GF or GFA mixture, but not the single oligosaccharides, reduced the allergic skin response and whey-IgG1 levels in whey-sensitized mice, compared to the control diet. Both GF and GFA increased the number of Foxp3+ cells in the proximal small intestine of whey - compared to sham-sensitized mice. Expression of Th2 and Th17 mRNA markers increased in the middle part of the small intestine of whey-sensitized mice, which was prevented by GF. By contrast, GFA enhanced Tbet (Th1), IL-10 and TGF-β mRNA expression compared to GF which was maintained in the distal small intestine and/or colon. CONCLUSIONS: Dietary supplementation with scGOS/lcFOS or scGOS/lcFOS/pAOS during sensitization, both effectively reduce allergic symptoms but differentially affect mucosal immune activation in whey-sensitized mice

Seeing historically: Goethe and Vygotsky’s ‘enabling theory-method’.

We can study dead forms from a distance, seeking to understand the pattern of past events that caused them to come into existence. We can, however, enter into a relationship with living forms and, in making ourselves open to their movements, find ourselves spontaneously responding to them, and in so doing, we can gain a sense of their character. In other words, from within our dialogically structured involvements with other living things, a kind of relationally responsive understanding, quite different from the referential-representational kind of understanding familiar to us in cognitive psychology, becomes directly available to us. Thus, rather than seeking to explain a child’s present activities in terms of their causes in the past, from the standpoint of an external observer, we can turn to a quite different aim: that of perceiving in a present behavior the possibilities and opportunities it offers for further developments. Orientation toward this aim is what I think is so special about both Vygotsky’s and Goethe’s historical methods of inquiry into the development of living forms
