the influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (beta vulgaris l. cv. ic) and a salt sensitive glycophyte (nicotiana rustica l. cv. basmas). low-level salinity (25 mm nacl) and high salinity (150 and 50 mm nacl for sugar beet and tobacco, respectively) were supplied in hydroponics. under low salinity shoot dry ...
The aim of this 3 × 3 factorial experiment on broilers was to investigate the effect of different dietary levels of potassium and chloride on chicken performance, carcass composition and dry matter content in excreta. 360 one-day-old Ross 308 chickens were allocated to 9 groups, in 5 replications of 8 birds (4 ♂ and 4 ♀). Chickens from 1 to 42 days of age were kept in cages with wire floors to ...
This study was carried out to determine the effect of L-arginine (L-Arg) levels in diet at the starter, grower and finisher phases on immune response, organ development, nitric oxide (NO) metabolism and colon motility in broilers. A total of 500 one-day-old Ross-308 broiler chickens of mixed sex were separated into one Arg-deficient group and four experimental groups. Each group was then divide...
Metabolizable energy (ME) required for basal metabolism, activity and growth was considered as the criterion for targeting specific increases in body weight (100 g/week) of broiler chicks during the grower phase (5-20 weeks) and its impact was evaluated on breeder performance. Broiler female chicks (460) from a synthetic dam line were randomly distributed to 4 test groups with 23 replicates of ...

onion thrips, thrips tabaci lindeman, is a broadly distributed pest that attacks a wide range of crops. to investigate the intra-specific morphometric variation and the genetic diversity of the species in iran, four populations from tobacco plus 18 populations from onion were studied in some 17 provinces of iran. morphological analysis, using principal components and canonical discriminant anal...
A Study on the Pattern of Self-reported Tobacco Addiction in Hypertensive Patients in Gujarat, India
Background: Both hypertension (HTN) and tobacco addiction pose a threat to the health, environment, and socioeconomic status (SES) of the people. When tobacco use disorder exists in people with HTN, it hastens the disease progress and causes early complications. The present study aimed to study the knowledge and practice of tobacco addiction in patients with HT...
Using an unknown input observer, with an output linearising feedback, an online estimator for the ventilation flow or rate is developed for natural ventilated greenhouses. The paper shows how to design, implement and tune such an estimator in practice and shows that it performs well. Furthermore the practical value for the grower is discussed. Copyright © 2005 IFAC
The growth-promoting effects of two dietary acidifiers based on formic acid were studied with 320 fattening pigs from ca 2 kg to ca 05 kg of body weight. The sorbate-coated formic acid contained formic acid and ammonium formate which were absorbed in diatomaceous earth and coated with potassium sorbate. The investigated liquid blend contained formic and lactic acids as the major components. The...
