this paper presents an inventory model for deteriorating items in which shortages are allowed. it is assumed that the production rate is proportional to the demand rate and greater than demand rate. the inventory model is developed by considering four different circumstances. the optimal of the problem is obtained with the help of mathematica 7 software. numerical examples are given to illustra...
Deterioration of seeds is an important factor to reduce seeds vigor and limit germination. The purpose of this research was to evaluate the influence of gibberellic acid hormone on recovery of seeds and improvement of quality and seedling growth in Varamin cotton seed, an experiment was conducted in a completely randomized way in three replications. Treatments included: two levels of deteriorat...
abstract seed deterioration of seed is one of the most important limiting or even hindering factors in germination. the main purpose of this study was to determine the effects of salicylic acid and gibberellic acid hormonal on improvement and prevailing seed deterioration in two sesame cultivars. this studywere carried out at the department of agronomy and plant breeding seed laboratories of co...
Physiological and biochemical changes during sunflower seed deterioration were studied during incubation for 2, 4, 6 and 8 days at 43 °C and a relative humidity of 100%. Parameters such as germination percentage, germination rate, seedling length, seedling vigor and protein decreased whereas electrical conductivity, fatty acids and lipid hydroperoxides increased during seed deterioration. Incre...
Ripening and senescence are the ultimate phases in the developmental events of fruits that result in the expression of the quality characteristics inherent to the fruit. Although it is difficult to demarcate a dividing point between ripening and senescence, the former can be designated as the quality-developing phase, whereas the latter predominantly involves the loss of quality. Degradation of...
The relations between language and thought in the normal person, and the connexion between the forms of their disturbance in the dysphasic, are questions which have aroused much discussion and little conclusion. But at least it would seem clear that the nearer an individual's daily occupation approaches to the purely intellectual, the more it is likely to be impeded by even a mild degree of dys...
The province of Quebec, historically known for its unusually high reproductive levels, has in the past few decades experienced a spectacular fertility decline. This more or less abrupt decline in fertility has corresponded with the socioeconomic transformation of this French-speaking province into a modern society. This paper presents a path analysis of period structural factors on fertility ch...
Reaction to medical, social, and genetic implications of Huntington's disease was evaluated by means of a questionnaire mailed to members of a lay organization concerned with this disease in the United States. One thousand and sixty-five of the approximately 2600 members chose to respond. Patients and those at high risk found physical disabilities most disturbing while mental deterioration and ...
The term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. Despite common points in images, the differences put Iran cities in different categories based on deteriorated textures. This classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. F...
