We present a method that allows for reconstructing non-stationary, time-varying gas flows around moving objects. Our work extends the background oriented Schlieren tomography (3D-BOS) acquisition technique to capture gas flows also in the presence of occluding objects. An algorithm is presented that exploits the unique properties of BOS background patterns to robustly segment occluding objects....

with the update of practical knowledge such as pharmacology by adding information taken from books composed by authors contemporary with him including ibn Wafid (see Bos’ introduction, pp. xvii–xxii). This short analysis illustrates the importance of publishing the Arabic texts of Maimonides’ medical works, when we explore the history of medicine. Bos has made a great contribution to the schola...

The bovine leukaemia inhibitory factor was isolated from a phage library and sequences for the gene, in addition to 1213 bp of 5' and 432 bp of 3' sequences, were obtained and compared with other mammalian leukaemia inhibitory factor genes. Comparisons indicated amino acid homologies ranging from 89.6% to 77.2% with the human and mouse homologues, respectively. Analysis of 500 bp of 5' regulato...

Chronic rejection (obliterative bronchiolitis) is the single most important cause of chronic allograft dysfunction and late mortality after lung transplantation. As this condition is difficult to prove using biopsy specimens, a clinical term, bronchiolitis obliterans syndrome (BOS) has been in use for >10 yrs to describe the progressive decrease of pulmonary function. However, before diagnosing...

Suckled Bos indicus  Bos taurus cows were used to compare a Select Synch/CIDR + timed artificial insemination (AI) protocol (SSC) vs a modified Co-Synch/CIDR protocol (COS). Five groups of suckled Bos indicus  Bos taurus cows were evaluated (n=659). Cows received GnRH and a CIDR on d 0. On d 7, SSC cows had their CIDR removed and received prostaglandin F2α (PGF2α), whereas COS cows had their ...

Bos indicus cattle, the preferred genetic group in tropical climates, are characterized by having a lower reproductive efficiency than Bos taurus. The reasons for the poorer reproductive efficiency of the Bos indicus cows include longer lengths of gestation and postpartum anestrus, a short length of estrous behavior with a high incidence of estrus occurring during the dark hours, and puberty at...

Two experiments were conducted to determine the urinary purine derivative (PD) excretion rates and to analyze potential variations in PD excretions between yak, Tibetan indigenous cattle, and their crossbreds under similar ecological environment, and to develop prediction equations based on PD excretion for estimating rumen microbial protein supply. Three Tibetan castrated male yaks, and simila...

In a school choice mechanism, school priorities are often based on student exam scores, by which student true ability may not be perfectly revealed. An ex-post fair matching mechanism (for example, Serial Dictatorship) can be undesirable in that it is not ex-ante fair: it may not match students with higher abilities to better schools, although it always matches students with higher scores to be...

Compared to other bone tumors, bone osteogenic sarcoma (BOS) continues to confer a much grimmer prognosis as the survival benefit of traditional chemotherapy treatment regimens is still unsatisfactory. Chemotherapy was demonstrated to be effective in eradicating both primary tumor and pulmonary metastases in the last century, with effective agents used in various combination regimens having cha...

The present investigation was aimed at studying 1.26 kb αS2-casein promoter gene in αS2casein gene locus between the three buffalo breeds. αS2 -casein promoter gene was amplifi ed by PCR using oligonucleotide primers standardized for Bos taurus species. The sizes of the amplifi cation products were similar. PCR amplicons are subjected to restriction digestion by the enzyme Eco RV, only an intac...
