A detailed examination on various aspects of the southwest monsoon over the Indian subcontinent using analyses and forecasts of the NCMRWF global data assimilation and forecast system for the years 1994 and 1996 is carried out in this study. Objective procedures developed by Ramesh et al. (1996) based on the monsoon 1995 data are employed in the present work. It is found that all the deterministic features of the summer monsoon viz., the onset, its advancement, stagnation/revival and the withdrawal, can reasonably by prognosticated after employing the objective methodologies and monitoring daily variations of certain derived quantities from the large scale analyses and forecasts. Further, a good correspondence of the observed large scale/synoptic scale circulation features and the observed rainfall etc. with the deterministic characteristics of the summer monsoon show a good prospect for real time prognosis of the important summer monsoon activities over the Indian subcontinent.

Broken and cracked eggshells cause major economic losses to the egg production industry. An F2 population of 262 hens obtained by crossing a strong egg shell line with a weak egg shell line of the White Leghorn breed was used for detecting the quantitative trait loci （QTL） affecting eggshell quality. The 2 lines were developed from the same founder population by two-way selection for egg shell strength with nondestructive deformation. Of the 1 014 microsatellite markers tested, 35 were mapped on 10 autosomal linkage groups. There was no informative marker on chromosome Z. The QTLs associated with 7 traits, i.e., body weight, short length of egg, long length of egg, eggshell strength, eggshell thickness （EST）, eggshell weight （ESW）, and egg weight （EW）, were identified. Highly significant （P〈0.01） QTLs associated with EST and ESW and a significant （P〈 0.05） QTL associated with EW were mapped to a region flanking ABR0545 and ABR0362 on chromosome 9. These QTLs are good candidates to be employed in the development of strategies for reducing the number of broken and cracked eggs in commercial layer houses by employing marker assisted selection.

The spatio-temporal variation of the tropopause height (TH) over the Indian region (5°N-35°N, 70°E-95°E) has been studied using monthly mean TH data, for 22-year period, 1965 to 1986. The study revealed that the stations south of 20° showed maximum TH in April / May and minimum in September. This variation in TH has been attributed to the corresponding variation of average sea surface temperature (SST) over ± 20° latitudinal belt over Indian Ocean, Arabian Sea and Bay of Bengal. Further the stations north of 20°N showed maximum in June and minimum in October/ November. This maximum in TH has primarily been attributed to the increased insolation and convection. Furthermore it is noticed that the anomaly of TH moved northwards during the period April to *** interannual variability of the Indian Summer Monsoon Activity (ismA) has been studied in relation to all India mean TH (at 12 GMT) for six months April through September. The composites of mean TH for good and bad monsoon years showed that all India mean TH is statistically higher in good monsoon years than in bad monsoon years. The relationship between ismA and all India mean May TH has been studied using the contingency table. The study suggested that the forecast of ismA could be prepared using mean May TH.

Temporal trends of perfluoroalkyl substances(PFASs)have been determined in the blood samples from several countries globally including a female population in Sweden recently,yet little is known about the time trends in the blood levels of these compounds in Swedish male populations over recent *** this study,the fourteen target PFASs consisted of four perfluorosulfonates(PFSAs)and ten perfluorocarboxylates(PFCAs)in the whole blood samples,collected from 153 Swedish elderly men during the period between 2008 and 2010,were analyzed via ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).As the dominant PFASs contaminants in the blood samples,perfluorooctane sulfonate(PFOS)showed the highest geometric mean(GM)at8.5 ng/mL,ranging from 1.7 to 29 ng/mL,while blood perfluorooctanoic acid(PFOA)contained the GM of1.8 ng/mL,ranging from 0.35 to 6.4 ng/*** the levels of these two compounds were lower than those determined in the blood samples of Swedish elderly populations derived from the late *** to the temporal trend analysis,over the three years,the blood levels of PFOS in Swedish male populations declined 16% per annum,while those of perfluoroundecanoic acid(PFUnDA)increased 6.1%per annum,which were consistent with those reported previously for the populations from other countries.

The quantum theory of dark soliton propagation in fibers is studied based on the linearization approximation. Then the uncertainties in photon number, phase, position （time） and momentum of quantized dark solitons are calculated. Finally, the squeezing of the dark soliton is investigated by using homodyne detection and compared with bright soliton case.

This note looks at the two similarity solutions of the Navier-Stokes equations in polar coordinates. In the second solution an initial value problem is reduced into generalized stationary kDV and hence integrable.

Aim: To identify the antifertility effect of intermittent oral administration of tamoxifen in male rat. Methods:Tamoxifen was administered orally at a dose of 0.4 mg·kg^(-1)·d^(-1) with an intermittent regime for 120 days. Treatedand control rats were mated with cycling female rats on days 60, 90 and 120 of treatment. The mated males were sacri-ficed and the weights of reproductive organs were recorded, and the serum levels of LH, FSH, testosterone and estradi-ol estimated by radioimmunoassay. In the female rats, the numbers of implantation sites, corpora lutea, and numbersof normal and resorbed foetuses were recorded on d 21 of gestation. The potency, fecundity, fertility index, litter sizeand post-implantation loss were then calculated. Results; The fecundity of male rats was completely suppressed bytamoxifen while the potency was maintained at the control level. The fertility index was significantly decreased. No vi-able litters were sired. Post implantation loss, indicative of non-viable embryos, was observed but was not significantlyincreased above the control level. The weights of the testes, epididymides, ventral prostate and seminal vesicles weresignificantly reduced. The blood LH and testosterone levels were significantly decreased, but not FSH and ***; Intermittent oral tamoxifen administration completely suppressed the fecundity of adult male rats withreserved potency.
