The study was carried out on four mature Jaffrabadi breeding bulls (4–6 years old) maintained at Cattle Breeding Farm, JAU, Junagadh for a period of 8 months during winter and summer. The seasonal and bull variations in sexual behavior traits were studied. A total of 64 observations (32 per season, 8 per bull) were availed at the fortnightly interval. The mean values/ scores for temperament (0–5 scale), libido (0–9 scale), penile erection (0–4 scale), protrusion (0–4 scale), intensity of thrust (0–4 scale), reaction time (sec) and Flehmen reaction (0, 1) during winter season were 1.28 ± 0.08, 6.75 ± 0.19, 3.22 ± 0.74, 2.88 ± 0.59, 3.15 ± 0.65, 125.00 ± 6.92 and 0.91 ± 0.43, respectively, while the respective values in summer season were 2.22 ± 0.07, 5.93 ± 0.43, 2.84 ± 0.65, 2.75 ± 0.59, 2.93 ± 0.13, 143.5 ± 7.07 and 0.88 ± 0.06. There were significant differences among seasons for temperament, libido and penile erection score of Jaffrabadi bulls. Significant differences among bulls were also found for libido score, the intensity of thrust and reaction time in the winter season, and for ejaculatory thrust in the summer season. All these traits were highly significantly and positively interrelated (r = 0.353 to 0.512), except Flehmen reaction and reaction time which were negatively correlated with all other behavioral traits (r = –340 to –0.499). Summer in general significantly exerted an adverse effect on the sexual behavior of Jaffrabadi bulls, and winter was the favored season. It could be concluded from the study that the Jaffrabadi bulls had good sexual behavior scores throughout both the seasons, however, bulls showed better sexual behavior during winter as compared to summer.

Solvolytic studies with triphenylvinyl-2-14C bromide (l-Br-2-14C) in HOAc–H2O and in 2,2,2-trifluoroethanol (TFE) containing 2,6-lutidine were carried out under a variety of conditions. Scramblings of the label from C-2 to C-l in the reaction product and in the unconsumed reactant were determined. For solvolyses in HOAc–H2O, scrambling was observed in the product, but not in the recovered reactant. The extent of scrambling was higher when the proportion of H2O in the solvent was lower. With a given solvent composition, the amount of scrambling did not change with reaction time, the average extents of scrambling being 9.6,12.7, 15.3, 16.7, and 18.4%, respectively, for solvolysis in 50, 60, 70, 80, and 90% HOAc. With 70% HOAc, the presence of about 3 equiv. of NaOAc or NaBr did not influence the extent of scrambling. For the reactions in TFE, there was scrambling in both the reaction product and the recovered reactant, indicating the occurrence of a return process, The presence of added Et4NBr did not affect the extent of scrambling, suggesting that the 1,2-phenyl shift occurred in the ion-pair stage and the return is, therefore, an ion-pair return. The amount of scrambling in the product and in the recovered reactant increased with increasing reaction time, but for a given reaction time, the extents of scrambling in the product and in the recovered reactant were the same. The mean values for the scrambling of the label from C-2 to C-l in the product and the recovered reactant, after a reaction time of 1, 2, 4, and 20 days at 150 °C, were 20.1, 30.0,40.0, and 44.1%, respectively. Mechanistic explanations for both reactions in HOAc-H2O and in TFE are discussed.

Hematological And Biochemical Parameters

Background: Environmental stress and transition period in buffaloes imposes significant changes in hemato-biochemical parameters. On this background the present study was attempted to evaluate biochemical parameters in transition buffaloes during summer and winter seasons. Methods: Thirty six advanced pregnant and non-pregnant Murrah buffaloes of around 5 years of age were randomly selected. Whole blood was collected from twelve buffaloes each in their transition period during winter and summer season for a period of five weeks and six non pregnant buffaloes for each season served as control. Haematological, biochemical parameters were estimated and THI was calculated in both the seasons. Result: The mean THI, TEC, Hb, MCH, MCHC, SOD activity and MDA levels were significantly higher (p less than 0.05) in summer compared to winter, while MCV and GSH activity was significantly higher (p less than 0.05) in winter compared to summer. No significant (p greater than 0.05) difference between seasons was observed with respect to TLC, monocyte and lymphocyte per cent. Moreover, Hb, SOD, GSH and MDA concentration differed significantly (p less than 0.05) throughout the transition period during summer and winter seasons, while TEC, MCV, MCH and MCV concentration did not change (p greater than 0.05) with transition period in both the seasons. The present study indicated that summer season had profound effect on hemato-biochemical parameters. While SOD, GSH and MDA could be used as markers of transitional stress in Murrah buffaloes.

Bryophytes are poikilohydric organisms that can be used as model plants to study desiccation tolerance mechanisms. The main objective of this study was to examine the activities of the antioxidant enzymes ascorbate peroxidase (APX), catalase (CAT) and guaiacol peroxidase (POD) in the rehydrated and desiccated states in Syntrichia ruralis (Hedw.) Web. & Mohr. from two slopes, one North-east (NE) and one South-west (SW) facing and collected in different seasons. Our results showed seasonal variation in the enzymatic activities of APX, CAT and POD between the slopes in both the rehydrated and desiccated states. The mean value of all the activities of APX, CAT and POD and MDA contents (a measure of lipid peroxidation) tended to be higher in moss cushions collected from the NE compared to the SW facing slopes except in summer season. The mean values of all enzymatic activities were higher in desiccated states as compared with rehydrated states. Protein content has lower values in summer and winter season. Differences in the antioxidant activities of the mosses growing on the two slopes may reflect adaptations to desiccation stress.

The present investigation was carried out to study the effect of vaccination on the sexual behavior of six Pandharpuri buffalo bulls. The bulls were vaccinated against HS-BQ in July and FMD-I in September and FMD-II in February. The work was divided into four periods, viz., control/pre-vaccination period (Nov-Jan), and post-HS-BQ, FMD-I and FMD-II vaccination periods. Overall mean libido and sexual behavior score of bulls during the pre-vaccination period was 90.76±0.19 percent, which significantly decreased for first three (76.65±2.79 to 79.17±2.39), two (77.50±1.71, 76.67±3.07) and one (79.15±2.71) week after FMD-II, FMD-I, and HS-BQ vaccination, respectively. Mean reaction time (seconds) of bulls during vaccination free period was 46.25±0.14, it increased significantly in first four (59.17±2.01 to 56.67±2.11), three (56.67±2.11 to 57.50±2.14) and one (57.50±2.81) week post-FMD-II, FMD-I, and HS-BQ vaccination, respectively. FMD-II (February) vaccination had a more harmful effect on sexual behavior and reaction time compared to FMD-I (September) vaccination, perhaps due to the succeeding summer season. It was concluded that sexual rest should be recommended for three, two and oneweek post-FMD-II, FMD-I and HS-BQ vaccination, respectively, return to normal sexual behavior in Pandharpuri buffalo breeding bulls.

This study was conducted to determine the seasonal variation of Cr, Ni, Cu, Zn, As, Cd and Pb concentrations in water from four coastal sites of Bangladesh. The mean concentrations of trace metals in the water samples in the range of each elements were Cr (2.6−15.3), Ni (5.1−77.5), Cu (10.2−510), Zn (5.0-1390), As (2.1−13.3), Cd (0.006−0.09), Pb (0.4−109 μg/l) in summer and Cr (3.6−43.7), Ni (10.8−42.4), Cu (7.3−45.2), Zn (18.0-73.9), As (4.0−19.7), Cd (0.025−0.087), Pb (2.8−34.8 μg/l) in winter. The mean concentrations of the metals in water followed a decreasing order of Zn > Cu > Pb > Ni > Cr > As > Cd in the summer and Zn > Ni > Cr > Cu >Pb > As > Cd in the winter. The water of Cox’s Bazar hatchery site showed the highest levels of Zn (1390), Cu (510) and Pb (109 μg/l) in summer while As (19.7 μg/l) showed highest in Cox’s Bazar Bakkhali estuary in the winter samples. The elevated level of Ni (77.5 μg/L) in the summer and Cr (43.7 μg/l) in the winter water samples were also found in the Sundarbans site. The mean concentrations of all estimated trace metals were higher in the winter than in the summer season. It was both in the Chittagong port and Meghna estuary. For the Meghna estuary, the highest concentration of Zn (36.0 μg/l) was observed in the water sample of winter season. Some trace metals exceeded the international quality guidelines. Suspended solid, temperature, rainfall, anthropogenic inputs and geomorphologic setup are influenced by seasonal vagaries which alter the variation of metal distribution. J. Biodivers. Conserv.

     The study was conducted to indicate the contamination of the local produced broilers carcasses by Escherichia coli O157:H7, and its effects on public health. Sixty samples of local produced Broilers were collected randomly from five different areas in Baquba center of Diyala governorate, (Iraq). Thirty samples to each were collected in summer, from the beginning of July to end of August, and in winter season from the beginning of December to end of January to investigate their microbial load. All summer samples had significantly (P<0.05) higher microbial count of Coli-form Bacteria, Escherichia coli and E.coli O157:H7 than winter samples, but there were no significant differences in the mean values of Escherichia coli count CFU/g, and E.coli O157:H7 count between summer and winter seasons. The conclusion of study showed that the contamination of local produced broilers by these bacteria was higher through summer as compared to winter season; the reason is because of temperature in summer which leads to growth and Proliferation of these bacteria and misuse of preparation and production of meat acts to increase the microbial load in these products.

An experiment was conducted at the Institute of Agriculture and Animal Sciences, Rampur, Chitwan, Nepal during the summer season of 2003 to evaluate the response of Arun 2 variety of maize to different levels of nitrogen under field conditions. The experiment was conducted using Randomised Complete Block Design (RCBD) with three replications. Results showed a highly significant difference among treatments with respect to yield. Application of 90 kg N per ha gave the highest grain yield (5.46 ton/ha) and 150 kg/ ha gave the lowest yield (4.91t/ha). But the non-significant results were found with respect to plant height, cob height, days to 50 % silking, days to maturity and number of plants per plot among treatments. The mean values for number of plants per plot, plant height, cob height, days to 50 % silking after sowing, days to maturity after sowing and yield /ha were found 21.3, 192.3 cm, 94.3 cm, 50.3, 87.5 and 5.18, respectively, Strong correlation of 0.81 and 1 were found between the traits plant height and cob height and days to 50 % silking and days to maturity respectively. In contrast, negative correlation was found between the traits plant height and yield, and cob height and yield. Key words: Nitrogenous fertiliser, yield component, maize J. Inst. Agric. Anim.

High speed cinefluorography was used to track articulatory movements preceding and following full-mouth tooth extraction and alveoloplasty in two subjects. Films also were made of a control subject on two separate days. The purpose of the study was to determine the effects of dramatically altering the structural dimensions of the oral cavity on the kinematic parameters of speech. The results showed that the experimental subjects performed differently pre and postoperatively though the changes were in different directions for the two subjects. Differences in both means and variabilities of kinematic parameters were larger between days for the experimental (operated) subjects than for the control subject. The results for the Control subject also showed significant differences in the mean values of kinematic variables between days though these day-to-day differences could not account for the effects found pre- and postoperatively. The results of the kinematic analysis, particularly the finding that transition time was most stable over the experimental conditions for the operated subjects, are used to speculate about the coordination of normal speech.

Second Wave

In order to model within-person (WP) variance in a reaction time task, we applied a mixed location scale model using 335 participants from the second wave of the Zurich Longitudinal Study on Cognitive Aging. The age of the respondents and the performance in another reaction time task were used to explain individual differences in the WP variance. To account for larger variances due to slower reaction times, we also used the average of the predicted individual reaction time (RT) as a predictor for the WP variability. Here, the WP variability was a function of the mean. At the same time, older participants were more variable and those with better performance in another RT task were more consistent in their responses.
