Kabupaten Jember masih menghadapi masalah gizi gangguan akibat kekurangan iodium (GAKI), sebagian besar kecamatannya termasuk dalam kategori daerah endemik GAKI. Salah satu penyebabnya adalah faktor goitrogenik sianida yang mengganggu pembentukan hormon tiroid. Keberadaannya pada beberapa sayuran yang biasa dikonsumsi masyarakat menyebabkan diperlukannya pola konsumsi dan proses pengolahan yang baik agar aman dikonsumsi. Penelitian ini bertujuan mengubah pola konsumsi goitrogenik sianida dan cara pengolahannya melalui penyuluhan gizi dan demonstrasi cara pengolahan pangan sumber goitrogenik sianida yang benar. Penelitian ini adalah sebuah penelitian kuasi eksperimental dengan rancangan pretest-posttest control design. Jumlah sampel sebanyak 196 ibu rumah tangga, terdiri dari 98 orang di setiap kelompok perlakuan dan kontrol. Penelitian dilakukan di Kecamatan Arjasa Kabupaten Jember pada bulan Maret hingga Mei 2013. Hasil penelitian menunjukkan adanya peningkatan konsumsi bahan mentah sumber goitrogenik sebesar 25,98 gram. Namun, tidak terjadi peningkatan konsumsi sianida, justru menurun sebesar 9,09 miligram pada kelompok perlakuan. Hal ini terjadi karena pemilihan cara pengolahan yang tepat sesuai materi intervensi, yaitu beralih ke kulub dan rebus berkuah. Namun penurunan ini tidak signifikan (p = 0,56). Materi tentang GAKI dan cara mereduksi kadar sianida pada bahan pangan sumber goitrogenik sianida bisa dijadikan materi penyuluhan dalam program pencegahan GAKI di Kabupaten Jember.Changes in Food Pattern and Food Processing of Source Substance Goitrogenic Cyanide Through Nutrition CounselingJember still encounter the problem of nutrition iodine deficiency disorders (IDD), most of the district are included in the category of endemic areas. One reason is the cyanide goitrogenic factors that can interfere with the function of the thyroid hormone. Its presence in some commonly consumed vegetables society, causes the need for patterns of consumption and good processing in order to make it safe for consumption. Cyanide is a precursor thiocyanate which disrupt the formation of thyroid hormones through two pathways, active transport and interfere with the activity of thyroid peroxidase. This study aimed to change food pattern and way of processing goitrogenic cyanide food stuff through nutritional counseling and demonstration of food processing to reduce cyanide in goitrogenic food stuff. The research was a quasy-experimental study with pretest-posttest control design. The number of samples 196 housewives, consist of 98 people in the respective treatment groups and control. The study was conducted in the District Arjasa Jember between March and May 2013. The result showed presence of increased consumption of raw materials sources goitrogenic cyanide of 25.98 grams, was not followed by an increase in the consumption of cyanide, which has decreased by 9.09 miligram in the treatment group. This occurs because of the selection of appropriate food processing, switching to boil and blanching (kulub). However, this decrease was not significant (p = 0.56). The material on IDD and how to reduce levels of cyanide in the food source of cyanide can be used as material counseling in prevention programs IDD in Jember.

Processes of classification (separation) of dry and damp dispersive materials are wide spread in metallurgy, construction, agriculture, in chemical, food, processing industry and in other branches. Therefore, constructors and technologists pay a lot of attention for rationalization of these processes and equipment for their realization in direction of increase of productivity and quality of classification, reliability of machines, decrease of power-consuming. In last decades in Ukraine with development of small and middle farming enterprises there is a tendency of increase of variety of grain raw materials by kinds, grades, humidity, sizes, mass, density and volume of particles. All this should consider food and processing enterprises which often work in quite intensive regime in a period of harvest. So, in last time there become more strong demands to efficiency of technological preparation of processes classification for selection of most rational method, equipment and regimes of processing with consideration of parameters of raw materials and demands of further technological processes (grinding, mixing, heating, cooking, frying etc). Because of that, there will be useful a method of automated technological projection of classification processes of dry dispersive materials, proposed in this article. The method allows to elaborate most effective technology of classification with consideration of volume of output program, time for its fulfilment, geometrical and structural-mechanical properties of processed material, characteristics of available equipment for classification and criterions of efficiency of elaborated technology – productivity and specified operational expenses for its realization. The method can be used as a base for elaboration of a computer program of automated synthesis and analysis of rational technological processes of classification of grain raw materials.

Large wind turbines typically have variable rotor speed capability that increases power production. However, the cost of this technology is more significant for small turbines, which have the highest cost-per-watt of energy produced. This work presents a low-cost system for applications where cost and reliability are of concern. The configuration utilizes the fixed-speed squirrel cage induction generator. It is combined with a variable ratio gearbox (VRG) that is based on the automated-manual automotive transmission. The design is simple, low cost and implements reliable components. The VRG increases efficiency in lower wind speeds through three discrete rotor speeds. In this study, it is implemented with active blades. The contribution of this work is a methodology that synthesizes the selection of the gearbox ratios with the control design. The design objectives increase the power production while mitigating the blade stress. Top-down dynamic programming reduces the computational expense of evaluating the performance of multiple gearbox combinations. The procedure is customizable to the wind conditions at an installation site. A case study is presented to demonstrate the ability of the strategy. It employs a 300 kW wind turbine drivetrain model that simulates power production. Two sets of wind data representing low and high wind speed installation sites were used as the input. The results suggest a VRG can improve energy production by up to 10% when the system operates below the rated wind speed. This is also accompanied by a slight increase in the blade-root stress. When operating above the rated speed, the stress decreases through the optimal selection of gear combinations.

The article presents the results of mathematical experiments with the system «Social potential of childhood in the Russian regions». In the structure of system divided into three subsystems – the «Reproduction of children in the region», «Children’s health» and «Education of children», for each defined its target factor (output parameter). The groups of infrastructure factors (education, health, culture and sport, transport), socio-economic, territorial-settlement, demographic and en-vironmental factors are designated as the factors that control the system (input parameters). The aim of the study is to build a model îf «Social potential of childhood in the Russian regions», as well as to conduct experiments to find the optimal ratio of the values of target and control factors. Three waves of experiments were conducted. The first wave is related to the analysis of the dynam-ics of indicators for 6 years. The second – with the selection of optimal values of control factors at fixed ideal values of target factors. The third wave allowed us to calculate the values of the target factors based on the selected optimal values of the control factors of the previous wave.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.
