Biochemical variation during ovarian vitellogenic growth in a hill stream teleost Garra mullya (Sykes) due to cadmium toxicity

Some biochemical variations during ovarian vitellogenic growth in hill-stream teleost Garra mullya due to sublethal concentration of cadmium has been discussed. Total protein, cholesterol and glycogen in ovary and liver along with gonadosomatic index (GSI) and hepatosomatic index (HSI) in Cd-treated fish exhibited significant decrease while liver glycogen remained unaltered

A homomorphism theorem and a Trotter product formula for quantum stochastic flows with unbounded coefficients

We give a new method for proving the homomorphic property of a quantum stochastic ow satisfying a quantum stochastic differential equation with unbounded coefficients, under some further hypotheses. As an application, we prove a Trotter product formula for quantum stochastic ows and obtain quantum stochastic dilations of a class of quantum dynamical semigroups generalizing results of [5

Hormonal profile and haematological parameters of male wistar albino rats treated with methanloic extract of Parthenium hysterophorus L.

Changes in hormonal and haematological level were assessed in male wistar albino rats treated with methanolic extract of Parthenium hysterophorus L. The result showed that methanolic extract treatment caused a significant (p < 0.01) reduction of 20 % and 40% in total RBC count (6.25 ± 0.025 to 5 ± 0.5 x 106/µL) and haemoglobin (17.1 ± 0.1892 to 10.2 ± 0.79 g / dL) respectively in treated rats over control. Unlike haematological parameters, hormonal profile showed a significant increase of 40% (p < 0.05), 200% (p < 0.01), 100% (p < 0.01) and 45.08% (p < 0.001) in follicle stimulating hormone, leutinizing hormone, prolactin and testosterone respectively. The reduction of blood parameters is due to less haemopoiesis or induction of anemia. The increase in hormone level may be a cause of prostate cancer in wistar albino rats

Initiation mode of explosives vis-a-vis blast performance

Considerable progress has been achieved in recent years in the whole field of blasting science and technology. This applies to explosives formulation, initiation systems and blast simulation through advanced numerical codes. The commercial explosives in the market today are not only generally cheaper and safer than before, but also more flexible in their applications, and also geared for easy transport and delivery into the boreholes in very large volumes. The theoretical treatment of detonation process under both ideal and non-ideal conditions are noteworthy, but they are still based on somewhat hypothetical situations. The actual variables that are essential parts of normal blasting practice have not yet been taken into account in such treatments. These include the various initiation practices employed to detonate a column of explosive, from single point initiation to multi-point initiation in blastholes, and the effect of detonation characteristics of both detonators and explosives under multi-deck and multi-hole blasting conditions. The in-the-hole VOD of an industrial explosive is dependent on explosive’s charge diameter and borehole diameter. The in-the-hole VOD of explosives was measured at four experimental sites in India for different borehole diameters i.e. 150 mm to 311 mm, but the explosive composition being same particle size, density, viscosity and loaded into boreholes with the same degree of confinement. The results of the studies demonstrated that there is definite relationship in in-the-hole VOD of the explosive and the diameter of the blasthole. The study also confirmed that the explosives initiated with concentrated boosters yielded higher VOD in comparison with those explosives that were initiated with multi-point priming. The measured increase in VOD of explosives for increasing diameter of holes was up to 24%. The rate of change in in-the-hole VOD of explosives increases with increasing borehole diameter. It can be further stated that the in-the-hole VOD of the explosive reaches a farly constant value after reaching a limiting/threshold diameter of 311 mm

pulmonary hypertension in left heart disease

Elevated left ventricular filling pressures are a general feature and hallmark of heart failure resulting from cardiac dysfunctions, essentially arising from and affecting the left ventricle [1, 2]. These disorders include heart failure due to diastolic and/or systolic malfunctions, as such heart failure with preserved (HFpEF) and without preserved; reduced (HFrEF) ejection fraction; valvular diseases; congenital cardiomyopathies; and congenital and acquired afflictions of left heart inflow and/or outflow tract [2, 3]. Thereby, the pressure of the left atrium will be elevated, either subsequently due to the increased LV-filling pressure [1, 4] or even initially, primarily in case of mitral stenosis [5]. In any case, left heart disease (LHD) is generally characterized by elevated left-sided filling pressures [4, 6]. The left-sided filling pressures are transmitted backwards, downstream, thereby causing an increase in pulmonary venous pressures [1, 5–7], a condition "of passive or congestive nature" as associated with pulmonary venous congestion [6]. In the literature this issue has in the past been called pulmonary venous hypertension (PvH) [8], or post-capillary pulmonary hypertension [9] or passive pulmonary hypertension [10]. Consequently, with the rise in pulmonary venous pressure, pulmonary artery pressure (PAP) also increases [11]

Temperature-dependent development of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) and its larval parasitoid, Habrobracon hebetor (Say) (Hymenoptera: Braconidae): implications for species interactions

Habrobracon hebetor (Say) is a parasitoid of various Lepidoptera including Helicoverpa armigera (Hübner), a key pest of different crops and vegetables. The development of both H. armigera and H. hebetor were simultaneously evaluated against a wide range of constant temperatures (10, 15, 17.5, 20, 25, 27.5, 30, 35, 37.5 and 40 °C). Helicoverpa armigera completed its development from egg to adult within a temperature range of 17.5–37.5 °C and H. hebetor completed its life cycle from egg to adult within a temperature range of 15–40 °C. Based on the Ikemoto and Takai model the developmental threshold (T o) and thermal constant (K) to complete the immature stages, of H. armigera were calculated as 11.6 °C and 513.6 DD, respectively, and 13 °C and 148 DD, respectively, for H. hebetor. Analytis/Briere-2 and Analytis/Briere-1 were adjudged the best non-linear models for prediction of phenology of H. armigera and H. hebetor, respectively and enabled estimation of the optimum (T opt) and maximum temperature (T max) for development with values of 34.8, 38.7, 36.3, and 43 °C for host and the parasitoid, respectively. Parasitisation by H. hebetor was maximal at 25 °C but occurred even at 40 °C. This study suggests although high temperature is limiting to insects, our estimates of the upper thermal limits for both species are higher than previously estimated. Some biological control of H. armigera by H. hebetor may persist in tropical areas, even with increasing temperatures due to climate change

Elementary excitations of trapped Bose gas in the large-gas-parameter regime

We study the effect of going beyond the Gross-Pitaevskii theory on the frequencies of collective oscillations of a trapped Bose gas in the large gas parameter regime. We go beyond the Gross-Pitaevskii regime by including a higher-order term in the interatomic correlation energy. To calculate the frequencies we employ the sum-rule approach of many-body response theory coupled with a variational method for the determination of ground-state properties. We show that going beyond the Gross-Pitaevskii approximation introduces significant corrections to the collective frequencies of the compressional mode.Comment: 17 pages with 4 figures.

Level structure of Si26 and its implications for the astrophysical reaction rate of Al25(p,γ)Si26

A study of the level structure of Si26 using in-beam γ-ray spectroscopy is presented. A full level scheme is derived incorporating all states lying below the proton threshold energy. The results are in good agreement with shell model predictions and one-to-one correspondence is found with states in the mirror nucleus Mg26. Additionally, a γ-decay branch is observed from a state at 5677.0(17) keV, which is assigned to a 1+ resonance important in the astrophysical reaction Al25(p,γ)Si26. The newly derived resonance energy, Er=159.2(35) keV, has the effect of decreasing the reaction rate at the novae ignition temperature of 0.1 GK by a factor of 2 when compared with the previous most precise measurement of this state
