By producing a severe depletion of vitamin K, it is possible to determine how much is needed daily to maintain a constant normal prothrombin time. A high degree of avitaminosis K can be produced in the chick by feeding a vitamin K-free diet, whereas in the dog the condi tion can be produced surgically by a cholecystnephrostomy, which consists in anas tomosing the pelvis of the right kidney with...

The activity o f single neurons with constant discharge frequencies in the area around the a-lobe o f the mushroom bodies o f the bee was recorded intracellularly. The spontaneous discharge fre­ quency o f these neurons ranged between 5 and 95 impulses per second. When stimulated, about 80 percent o f the neurons responded to at least one o f five different sensory modalities: scent; light; air...

The island of Curacao in the Netherlands Antilles lies 60 miles north of northwestern Venezuela. The island is 38 miles long and 7 miles wide at its broadest point, 2tëmiles at the narrowest. The population is roughly 120,000; 75% are locally born negroid. Autopsy records for the period 1936-1960 showed esophageal cancer to be the most com mon malignant tumor for both men and women among these...

Various feature descriptions are being employed in logic program ming languages and constrained based grammar formalisms The com mon notational primitive of these descriptions are functional attributes called features The descriptions considered in this paper are the possi bly quanti ed rst order formulae obtained from a signature of binary and unary predicates called features and sorts respect...

Let $$T_{n}$$ be an arc-colored tournament of order n. The maximum monochromatic indegree $$\varDelta ^{-mon}(T_{n})$$ (resp. outdegree ^{+mon}(T_{n})$$ ) is the number in-arcs out-arcs) a same color incident to vertex . irregularity $$i(T_{n})$$ difference between and A subdigraph H digraph D called rainbow if each pair arcs in have distinct colors. In this paper, we show that v with ^{-mon}(T...

A total of 50 samples of poultry feed mixtures of Slovak origin were analysed for fumonisin B(1) and B(2) (FB(1), FB(2)) and moniliformin (MON) using SAX-clean up procedure being detected by high pressure liquid chromatography with mass spectrometry (HPLC-MS) and diode array detection (HPLC-DAD), respectively. The samples were also simultaneously investigated for Fusarium species occurrence, an...

Aims. We investigate the structure of a field around the position of V838 Mon as seen in the lowest CO rotational transitions. We also measure and analyse emission in the same lines at the position of V838 Mon. Methods. Observations have primarily been done in the 12CO J = 2→1 and J = 3→2 lines using the KOSMA telescope. A field of 3.4 squared degrees has been mapped in the on-the-fly mode in t...

Probabilistic models of sequences play a central role inmost machine translation, automated speech recognition,lossless compression, spell-checking, and gene identifica-tion applications to name but a few. Unfortunately, real-world sequence data often exhibit long range dependencieswhich can only be captured by computationally challeng-ing, complex models. Sequence d...

Sudden and intermittent locking of the elbow joint is a com- mon complaint among patients who commonly demonstrate degenerative changes in the elbow. Common causes of elbow locking include acute trauma, osteochondritis dessicans, synovial chondromatosis, and osteoarthritis. Two cases involving patients with symptoms of elbow locking secondary to reasons other than loose bodies within the joint ...
