Hydrocyclones are used as pre-filter to reduce suspended particles in irrigation water on the subsequent filters. The aim of study was determine separation efficiency (SE) hydrocyclones, called H1, H2 and H3 according inlet/outlet diameters, at velocities 1.0 (V10), 1.5 (V15) 2.0 (V20) ms-1, sands diameter 0.5 (D05), (D10), (D15), (D20) 2.5 (D25) mm. Therefore, a hydrocyclone laboratory test sy...

Resumo O objetivo do estudo foi verificar a eficiência e ovulação após administração de diferentes indutores para sincronização da em vacas corte. Cento oito não-lactantes foram distribuídas grupo controle (GC; não tratadas; n=28); benzoato estradiol (BE) (GBE; 17 beta-estradiol (17ßE) (G17ßE; n=28) deslorelina (DES) (GDES; n=24). No dia menos 11 (D-11) protocolo, o GC recebeu cloprostenol exam...

Spinal dural arteriovenous fistulas (SDAVF) account for about 70% of all spinal AV shunts. We report on a 56-year-old male patient with progressive neurological symptoms. Preand post-contrast MR imaging of the spine, including contrast-enhanced MR angiography was done on a 1.5 T MR scanner. In addition a special (pre-contrast) 3D turbo-spin-echo sequence with variable flip angle evolution (SPAC...

In this study we demonstrated that CD4(+) T cells from STAT4(-/-) mice exhibit reduced IL-12R expression and poor IL-12R signaling function. This raised the question of whether activated STAT4 participates in Th1 cell development mainly through its effects on IL-12 signaling. In a first approach to this question we determined the capacity of CD4(+) T cells from STAT4(-/-) bearing an IL-12Rbeta2...

Vibriophage D10, a member of the Vibrio cholerae O-1El-Tor phage typing scheme, is used to detect the spread of the cholera epidemic and belongs to the Myoviridae family. The outer sheath of the tail of vibriophage is highly contractile in nature. We have used electron microscopy and computational image-processing techniques to determine the structure of this contractile tail sheath. The three-...

Official guidelines for the on-site treatment of domestic sewage have recently been published by the Danish Ministry of Environment as a consequence of new treatment requirements for single houses and dwellings in rural areas. This paper summarises the guidelines for vertical constructed wetland systems (planted filter beds) that will fulfil demands of 95% removal of BOD and 90% nitrification. ...

The effectiveness of radiation treatment in eliminating Salmonella Typhimurium and Listeria monocytogenes on laboratory inoculated ready-to-eat sprouts was studied. Decimal reduction doses (D10-values) for Salmonella Typhimurium and L. monocytogenes in dry seeds of mung (green gram), matki (dew gram), chana (chick pea), and vatana (garden pea) ranged from 0.189 to 0.303 kGy and 0.294 to 0.344 k...

Purpose: To investigate if ellagic acid exerts neuroprotective effects in hypoxic-ischemic (HI) brain injury by inhibiting apoptosis and inflammatory responses. Methods: Separate groups of rat pups from post-natal day 4 (D4) were administered with ellagic acid (10, 20 or 40 mg/kg body weight) orally till post-natal day 10 (D10). On D10, the rats were subjected to HI brain injury. Following HI i...

BACKGROUND Wealth quintiles derived from household asset indices are routinely used for measuring socioeconomic inequalities in the health of women and children in low and middle-income countries. We explore whether the use of wealth deciles rather than quintiles may be advantageous. METHODS We selected 46 countries with available national surveys carried out between 2003 and 2013 and with a ...

Sphingosine 1-phosphate (S1P), a pleiotropic lysophospholipid, regulates signal transduction pathway via G-protein-coupled receptors termed S1P1-5 in several types of the cells including lymphocytes. Higher levels of S1P4 mRNA as well as S1P1 mRNA are expressed in lymphoid tissues such as the spleen, thymus, lymph nodes, and Payer's patches. In contrast to S1P1 that plays an essential role in l...
