In response to an infection, proinfl ammatory cytokines stimulate lymphocytes to take up nutrients so that they can proliferate and mount an immune response. Once the infection is cleared, however, cytokine levels decline and the lymphocytes’ nutrient supply is abruptly cut off. Most of the cells quickly die by apoptosis, but a small fraction survive and differentiate into longlived memory cell...

Five shipments of feeder calves (965 head hauled in 11 drop-center trailers) were shipped 1,600 km by tractor trailer from Algood, Tennessee, to Bushland, Texas, during the fall seasons of 1976, 1977 and 1978. Shrink, incidence of shipping fever and subsequent feedlot performance of these feeder calves were analyzed. There were significant differences in shrink and subsequent feedlot performanc...

Kaca merupakan material yang banyak ditemui dikehidupan sehari-hari, biasanya berupa botol, glassblock, kaca mobil, lembaran dan berbagai macam produk lainnya. Proses produksi terdiri dari beberapa tahapan, mulai pencampuran bahan baku, peleburan, pencetakan, pendinginan, pengecekan kualitas, packing sebelum sampai kepada customer. sangat berpengaruh untuk menjaga kualitas botol cacat kotoran. ...

Rapid transformatIon of discoid hemoglobin SS erythrocytes into grossly distorted sickled forms suggests alteration of surface/volume ratio. We, therefore, examined the effect of deoxygenation on red cell volume. ‘31llaholed albumin was used as a marker of plasma volume in normal (Hb AA), sickle (Hb SS), and sickle-C (Hb SC) blood. Heparinized blood was incubated for 30 mm at 37#{176}Cin a tpno...

Recent research has demonstrated that verbal overshadowing occurs when a witness is forced to provide details of the culprit that are not readily available, but the effect does not occur when the witness is warned to provide only the information they are absolutely sure of (Meissner et al., 2001). The present study attempts to replicate this effect and to further examine the instructional manip...

When learning a dependence from data, to avoid overfitting, it is important to divide the data into the training set and the testing set. We first train our model on the training set, and then we use the data from the testing set to gauge the accuracy of the resulting model. Empirical studies show that the best results are obtained if we use 20-30% of the data for testing, and the remaining 70-...

The Universe is magnetized. This is true on “small” length scales, such as in planets and stars, and over much larger scales, such as across the tenuous gas in galaxies and galaxy clusters and, possibly, the even more rarefied intergalactic medium. Physicists are fairly certain that these magnetic fields weren’t created in the big bang (the reason has to do with the symmetry of Maxwell’s equati...
