I N PREVIOUS work, it was found that the ‘osmotic ceiling’ in the urine from the desert rodents Heteromyidae is exceptionally high compared with the osmotic ceiling in urine from other mammals. This mechanism is of importance to water conservation. The general objective of the further investigations was to find in what respects the function of the heteromyid kidney differs from that of other ma...

Abstrak. Tanaman padi (Oryza sativa L.) merupakan tanaman pangan utama dan komoditi strategis bagi Indoesia. Produksi nasional belum mampu mencukupi kebutuhan penduduk banyak, kebijakan yang dilakukan seperti penggunaan varietas unggul, pembangunan sarana irigasi, subsidi benih, pupuk, pestisida dalam meningkatkan produksi secara nasional. Salah satu hal terpenting yaitu dengan menyediakan pupu...

Objective(s): Hyperglycemia promotes oxidative stress that plays a crucial role in the pathogenesis of Diabetic nephropathy (DN). In this study, we investigated the synergism effects of hydroalcoholic extract of Urtica dioica and pioglitazone (PIO) on the prevention of DN in streptozotocin induced-diabetic mice. Materials and Methods: Forty-two mice were divided into six groups as follows: non-...

in order to evaluate the effects of seed priming and different levels of nitrogen on yield and yield components of two corn (zea mays) hybrids, an experiment was carried out as split plot factorial based on a randomized complete block design (rcbd) with four replications in agricultural research station of shahrood university of technology. the treatments were urea levels (150, 250, 350 kg/ha) ...

Foliar urea application on barley plants increased leaf urease activity for 5 hours with a peak of 20-fold at 2 hours. To discern the mode of urease induction, urea with or without inhibitors and [35S]methionine were incubated with leaf sections for different lengths of time. Urease was extracted, partially purified, electrophoresed, and then quantified by fluorogram. Five urease (U) isozymes w...

Sixteen Friesian cows were used in Expt 1 to measure the effect of substituting urea-N with fishmeal-N either in early lactation (Part 1) or in mid-lactation (Part 2). In Part 1 (days 15-84 of lactation) the major N constituent of the concentrate was urea (U), urea-N: fishmeal-N in the ratio 2:1 (UF) or 1:2 (FU), or fishmeal (F). In Part 2 (days 84-175 of lactation) only urea (UM) and fishmeal ...

According to urgent need of corn to nitrogen and since this element play a main role in improving of yield corn, thus, in order to investigate the effect of different levels of urea on yield and yield components of corn 704, an experiment was conducted randomized block with three replications in cropping year of 2012. Experimental treatments included six levels of urea (0, 30, 60, 90, 120 and 1...

Two field experiments were conducted to know the effect of different doses of nitrogen fertilizer on the growth, botanical parameters and yield of maize and jumbo fodder cultivated with cowpea as inter crop and evaluation of silage. The experimental plots for Jumbo with cowpea and maize with cowpea were applied to nitrogen (N2) levels as urea 0, 100, 150kg ha-1 and 0, 150, 220 kg/ha, respective...
