The importance of shea tree to the people of south-western Nigeria cannot be over emphasized considering both the economic and environmental uses of the tree. However, efforts have not been made to propagate its production by the farmers as the shea tree still grows in the wild state. It would be worthwhile to investigate farmers’ perception of shea nut tree as an economic tree and their attitu...

Habitually, capuchin monkeys access encased hard foods by using their canines and premolars and/or by pounding the food on hard surfaces. Instead, the wild bearded capuchins (Cebus libidinosus) of Boa Vista (Brazil) routinely crack palm fruits with tools. We measured size, weight, structure, and peak-force-at-failure of the four palm fruit species most frequently processed with tools by wild ca...

for a comparison and grouping of 72 almond cultivars and genotypes, 30 traits including; 12 phenological and vegetative characters plus 18 traits related to nut and kernel were assessed, according to almond universal descriptor. the results revealed that some such traits as growth habit, flower color, nut weight, shell hardness and kernel taste carried high coefficients of variation. simple cor...

portantly, loss of fear. Later work indicated that the reduced fear in resected monkeys was due specifically Los Angeles, California 90095 to damage in the amygdala. Consistent with its general role in fear, reports began to emerge that the amygdala was also required for aversive learning, including the Pavlovian fear conditioning is a ubiquitous form of learn-acquisition of conditioned avoidan...

Objectives: To review the pro and con arguments for a laparoscopic approach for the treatment of upper urinary tract cancer. Methods: Fourteen series comparing open nephroureterectomy (NUT) with laparoscopic NUT have been studied with regards to cancer control and related morbidity. Results: Event though the open approach is still the gold standard treatment, the laparoscopic approach has shown...

The aim of this paper is to show the fruitfulness and fecundity of the authors' proof-theoretic analysis of logic programming (both for definite and normal programs). It is based on a simple logical framework that goes under the name of regular search spaces. The challenge faced here is to give a treatment in proof-theoretic terms of the issue of negation, which has been one of the toughest pro...

Canarium ovatum oil Engl. (pili nut oil) was extracted by using cold press method and then the physico-chemical properties of the oil samples, roasted pili nut oil (RPNO) and unroasted pili nut oil (UPNO) such as iodine value (IV), peroxide value (PV), acid value (% FFA), solid fat content (SFC), fatty acid composition and triacylglycerol (TAG) composition were determined. The percentage of oil...
