N-Alkylnitrilium and N,N-dialkylcyanamidium salts 1 and 2 undergo ene reactions with cyanamides 4 to afford 2-azoniaallene salts 7 and 9 in which the N-alkylnitrilium salts 1 react as the ene, and the cyanamides 4 react as the enophile components. Competing with the ene reaction, N-alkylnitrilium salts 1 undergo [2++2+2] cycloaddition to furnish triazinium salts 8. 2-Azoniaallene salts react wi...
BACKGROUND Identifying factors influencing plant management allows understanding how processes of domestication operate. Uncertain availability of resources is a main motivation for managing edible plants, but little is known about management motives of non-edible resources like medicinal and ceremonial plants. We hypothesized that uncertain availability of resources would be a general factor m...
To study the effects of different combinations of auxin (IBA, NAA) and cytokinin (BAP, TDZ) regulators, basal salts (MS, WPM, NN) and gelling agents (Gelrite and Plant Agar) on the growth and development of seedless grape explants (cv. Bidaneh Soltani), a factorial experiment was conducted based on a completely randomized design. The number and length of grown shoots were analyzed as two main c...
Angiotensin I-converting enzyme (ACE) is known to catalyze the conversion of angiotensin-I to angiotensin-II, which is the biologically active peptide elevating blood pressure, thereby being implicated in the pathogenic process of hypertension. Therefore, ACE inhibitory substances are expected to reduce the blood pressure in hypertensive patients. Then, the aqueous extracts were prepared from t...
A new method for determining the acid values (AVs) of edible oils based on the OH stretching band was developed. The oil sample was diluted with carbon tetrachloride and was placed in a quartz cuvette with a thickness of 1cm to record the FTIR spectrum. The peak at 3535cm(-1), which corresponds to the OH stretch of the carboxyl group in free fatty acids, together with the peak valley at 3508cm(...
The effects of coatings based on sodium alginate (S.A) and carboxyl methyl cellulose (CMC) on the color and moisture characteristics of potato round slices were investigated. It is the first time that this combination of polysaccharides is used as edible coating which alone had the best performance as inhibitor of potato color discoloration during the storage of 15 days at 4C. When ascorbic aci...
We compared the effects of reinforcing compliance with either positive reinforcement (edible items) or negative reinforcement (a break) on 5 participants' escape-maintained problem behavior. Both procedures were assessed with or without extinction. Results showed that compliance was higher and problem behavior was lower for all participants when compliance produced an edible item rather than a ...
Rice is the major foodgrain of the world and it is the principle cereal consumed in India and other parts of Asia1. Milling of paddy to obtain edible rice grain yields two major byproducts of economic and nutritional importance, namely, paddy husk and rice bran. Paddy husk has no food value but has several industrial uses. Rice bran, on the other hand, can serve as an animal feed, as a human fo...
We assessed the effects of individually defined small, medium, and large periods of presession access to edible and nonedible reinforcers on response rates during sessions in which responding produced access to identical reinforcers. Any presession access to an edible reinforcer decreased response rates for 1 participant, and small and medium periods of presession access to nonedible reinforcer...
BACKGROUND A comparative food ethnobotanical study was carried out in fifteen local communities distributed in five districts in the Palestinian Authority, PA (northern West Bank), six of which were located in Nablus, two in Jenin, two in Salfit, three in Qalqilia, and two in Tulkarm. These are among the areas in the PA whose rural inhabitants primarily subsisted on agriculture and therefore st...
