A system verification strategy based on the BST infrastructure

A good verification strategy should bring near the simulation and real functioning environments. In this paper we describe a system-level co-verification strategy that uses a common flow for functional simulation, timing simulation and functional debug. This last step requires using a BST infrastructure, now widely available on commercial devices, specially on FPGAs with medium/large pin-counts.

Board-level prototype validation: a built-in controller and extended BST architecture

Prototype validation is a major concern in modern electronic product design and development. Simulation, structural test, functional and timing debug are all forming parts of the validation process, although very often addressed as dissociated tasks. In this paper we describe an integrated approach to board-level prototype validation, based on a set of mandatory/optional BST instructions and a built-in controller for debug and test, that addresses the late mentioned tasks as inherent parts of a whole process

Strategier för presentationav arbetsprover inom grafiskdesign : hur en arbetssökande grafiskdesigner bäst ”säljer sig själv” tillanställning

För att få drömjobbet inom en konkurrenskraftig bransch som grafiskdesign krävs det lilla extra. Syftet med denna undersökning är att ta redapå vad detta extra är och därigenom underlätta för arbetssökandegrafiska designers på vägen till drömjobbet.Genom tre djupgående intervjuer med anställda på medelstora byråer iMellansverige undersöktes vad arbetsgivare uppskattar och förväntar sigav en arbetssökande grafisk designer. Frågeställningen behandladeportfolions framtid med branschens digitalisering som bakgrund, samthur en arbetssökande fångar arbetsgivarens intresse.Resultatet visar att även om portfolion utgör en stor del av underlaget förrekrytering av personal, är personen bakom portfolion och vad den haratt berätta om innehållet det som är viktigast. En portfolio som intebeskriver sammanhang duger inte som marknadsföringsmaterial. Attvårda det personliga varumärket framstår som viktigt för framgång. Dendigitala portfolion dominerar marknaden, men fysiska arbetsproverupplevs som ett möjligt sätt att stå ut från mängden. Digitala nätverkmottas positivt av branschen, men webbplatser anses ha mer substans.

Effect of recombinant bovine somatotropin (bST) on follicular population and on in vitro buffalo embryo production

The objective of this study was to evaluate the effect of bovine somatotropin (bST) on ovarian follicular population in buffalo heifers and its influence on oocyte quality, recovery rates and in vitro embryo production. We tested the hypothesis that bST treatment in buffalo females submitted to an ovum pick-up (OPU) program Would improve the number of follicles recruited, oocyte quality and in vitro embryo production. A total of 10 heifers were assigned into two treatment groups: group bST (n = 5; receiving 500 mg of bST in regular intervals) and control group (n = 5; without additional treatment). Both groups were subjected to OPU sessions twice a week (every 3 or 4 days), for a total of 10 sessions per female, although due to procedural problems, only the first five OPU sessions produced embryos. The number of follicles and the diameters were recorded at all OPU sessions. The harvested oocytes were counted and classified according to their quality as either A, B, C, D or E, with A and B considered good quality. Cleavage and blastocyst production rates were evaluated 2 and 7 days after in vitro fertilization, respectively. The bST treatment increased the total number of antral follicles (> 3 mm in diameter; 12.2 compared with 8.7: p, < 0.05) and of small antral follicles (< 5 mm; 9.1 compared with 6.5; p < 0.05) per OPU session. The bST also tended to increase the number of oocytes recovered per session (5.2 compared with 4.1; p = 0.07), and enhanced the percentage of good quality oocytes (48.8% compared with 40.6%; p = 0.07), bST showed no effect on cleavage and blastocyst production rates (p > 0.05). The significant effects of performing repeated OPU sessions were decreasing the follicular population (p < 0.001) as well as the number of follicles aspirated (p < 0.001), and oocytes recovered (p < 0.02). In conclusion, bST treatment improves the follicular population, demonstrating its possible application in buffalo donors submitted to OPU programs. (c) 2008 Elsevier B.V. All rights reserved.

Efeito da utilização da somatotropina bovina recombinante (bST) sobre a produção de leite em búfalas

O objetivo deste trabalho foi estudar o resultado da utilização da somatotropina bovina recombinante (bST) atuando na produção de leite em búfalas da raça Murrah. Empregaram-se 28 búfalas multíparas da raça Murrah, divididas em dois grupos homogêneos de 14 animais, recebendo os seguintes tratamentos: Grupo 1 ¾ Controle (solução salina) e Grupo 2 ¾ 500 mg de bST/cabeça a cada 14 dias, durante 7 meses. Búfalas tratadas com bST exibiram incrementos de 48,52%, 32,80% e 32,80% nas produções total de leite, corrigida, depois, para 4% de gordura e média diária, respectivamente. A somatotropina elevou a produção total de gordura sem alterar a porcentagem dela no leite. A administração de bST não afetou a porcentagem de proteína do leite todavia, a produção total de proteína foi aumentada. Quanto à duração da lactação, o tratamento com bST diferiu do controle, o que demonstra a maior persistência da lactação de búfalas tratadas com bST.

Effects of dominant follicle aspiration and treatment with recombinant bovine somatotropin (BST) on ovarian follicular development in Nelore (Bos indicus) heifers

Follicle ablation has been recognized as an efficient method of follicular wave synchronization. Treatment with recombinant bovine somatotropin (BST) has been shown to enhance follicular development in <(Bos taurus)under bar>. This experiment assessed the effects of these treatments in Nelore (<(B. indicus)under bar>) heifers. Eight cycling Nelore heifers were randomly assigned to 3 different treatments. on Day 2 of a synchronized cycle (Day 0 = day of ovulation), heifers assigned to Treatments 1 and 2 received 2 mL of saline, whereas heifers assigned to Treatment 3 received 320 mg of BST. on Day 5, the first-wave dominant follicle was ablated by ultrasoundguided transvaginal aspiration in heifers in Treatments 2 and 3, and all heifers received an injection of prostaglandin on Day 11. Aspiration of the dominant follicle advanced and synchronized (P < 0.05) the day of second-wave emergence (6.9 +/- 0.1 vs. 8.4 +/- 0.4) and the day of the pre-wave FSH peak (6.0 +/- 0.0 vs. 6.9 +/- 0.4), and increased FSH peak concentrations (381 +/- 21 vs. 292 +/- 30; pg/mL; P < 0.01). Recombinant bovine somatotropin treatment caused a two-fold increase in plasma insulin-like growth factor-I (IGF-I) concentrations (P < 0.001) and resulted in a 36% increase in the number of small follicles (<5 mm; P < 0.001) compared with saline-treated heifers. In summary, in agreement with previous reports on <(B. taurus)under bar>, dominant follicle aspiration synchronized ovarian follicular development, and BST treatment increased peripheral concentrations of IGF-I in Nelore heifers. Recombinant bovine somatotropin also increased the number of small follicles, but this response appeared to be inferior to that reported for <(B. taurus)under bar>. (C) 2000 by Elsevier B.V.

Effects of BST and high energy diet on gene expression in mammary parenchyma of dairy heifers

The objective of this study was to determine the effects of dietary energy and recombinant bovine somatotropin (bST) injection to identify genes that might control mammogenesis. Total RNA was extracted from the parenchymal tissue of 32 heifers randomly assigned to one of four treatments: two diets (a standard diet and a high energy, high protein diet), each with or without bST. To perform microarray experiments, RNA samples were pooled (2 animals/pool) before reverse transcription and labeling with Cy3 or Cy5. A 4-node loop design was used to examine the differential gene expression among treatments using a bovine-specific cDNA micro array (National Bovine Functional Genomics Consortium Library, NBFGC) containing 18,263 unique expressed sequence tags (EST). Significance levels of differential gene expression among treatments were assessed using a mixed model approach. Injection of bST altered the expression of 12 % of the genes on NBFGC slide related to tissue development, whereas 6% were altered by diet. Administration of bST increases the expression of genes positively related to cell proliferation and mammary parenchyma to a greater extent than a high energy diet. © 2013 Sociedade Brasileira de Zootecnia.

Lika barn leka bäst? - en studie om lågstadiebarns fördomar mot personer med invandrarbakgrund

Syftet med denna uppsats är att genom kvalitativa intervjuer belysa om barn med svensk bakgrund i lågstadieåldern (d.v.s. 7-9 åringar) har fördomar mot personer med invandrarbakgrund. Med ordet fördomar benämner vi uppfattningar och föreställningar om en annan grupp som stör personens kritiska tänkande. Personer med invandrarbakgrund benämns som en person som är född utanför norden och skiljer sig från den svenska normen utseendemässigt. Vi har också jämfört två klasser en utan och en med fler elever med invandrarbakgrund för att se om det visade någon skillnad i attityderna mot invandrare i de olika klasserna. Fem barn i vardera klass blev intervjuade. Barnen fick svara på ett antal relativt öppna frågor angående deras inställning och kännedom om personer med invandrarbakgrund. Elevernas svar analyserades utifrån tidigare forskning om barns utveckling och fördomars uppkomst. Utifrån barnens svar kunde vi se att de hade fördomar mot personer med invandrarbakgrund. Då de båda klasserna jämfördes visade det sig att de var väldigt lika, men att man kan urskilja vissa små skillnader, dessa skillnader visade på att eleverna i klassen utan elever med invandrarbakgrund var lite mer fördomsfulla. Vi fick fram att snällhet var viktigt samt att förstå varandras språk. Barnen är också väldigt medvetna om hudfärg.
