Response of fennel (Foeniculum vulgare Mill.) to phosphorus and zinc fertilization in a loamy sand soil
The field experiment was conducted with four levels of phosphorus (0, 20, 40, and 60 kg ha-1) and four levels of ZnSO4 (0, 15, 30 and 45 kg ha-1) to study their effects on growth and yield of fennel. Application of P upto 40 kg ha-1 significantly increased days to 50% flowering, plant height, number of branches, number of umbels plant-1, number of umbellets umbel-1, seeds umbel-1, seed and stover yield, net return and B:C ratio. The delay in 50% flowering, plant height, number of branches plant-1, number of umbels plant-1, number of umbellets umbel-1 and seeds per umbel-1, seed and stover yield, net return and B:C ratio increased significantly upto 30 kg ZnSO4 ha-1. The combined application of P @ 40 kg ha-1 and Zn @ 30 kg ZnSO4 ha-1 was significantly superior with respect to umbels plant-1, seed and stover yield as compared to other combinations of P and ZnSO4. The economic optimum dose of P and ZnSO4 was computed as 53.85 kg ha-1 with response of 1245.66 kg ha-1 and 39.03 kg ha-1 with the response of 1255.94 kg ha-1, respectively.
 
Design and Performance Analysis of a Switched Reluctance Motor Using Finite Element Analysis and Magnetic Equivalent Circuit Model
By being magnet-free, and mechanically robust with a longer constant power range, switched reluctance motor (SRM) is gathering much attention as a potential choice to propel electric vehicles (EVs) and hybrid electric vehicles (HEVs). This paper comprehensively investigates the performance sensitivity to geometric design variables such as rotor diameter, pole arc angles, and yoke thicknesses for an SRM using static two-dimensional (2D) electromagnetic Finite-Element Analysis (FEA). The reason for the change in static characteristics due to variation in reluctance between SRM designs has not been detailed previously. This is addressed by the magnetic equivalent circuit (MEC) model that simplifies the design analysis. Results indicate that stator pole reluctance needs to be given due importance while studying the influence of rotor diameter. Also, it is imperative to set an adequate thickness of the stator and rotor yokes to minimize the effect of saturation on the performance. Rotor diameter and stator pole arc angle have a pronounced influence on the performance while the influence of rotor pole arc angle and yoke thicknesses was relatively less
Cytological detection of microfilaria in unsuspected clinical scenario
Filariasis is a major public health problem in tropical countries, including India. Fine needle aspiration cytology plays an important role in prompt recognition of disease. Aim was to highlight the role of fine needle aspiration cytology as a simple and cost effective tool to detect microfilarial infestation. A retrospective study of 10 cases in which fine needle aspiration cytology was done and was useful in detecting microfilaria. Patient’s age were ranging from 19-62 years. M:F ratio being 7:3. Out of ten cases, maximum cases of microfilarial detection was reported in soft tissue swelling (four cases), followed by lymph node swelling (three cases), thyroid swelling (two cases) and breast swelling (one case). Careful screening of fine needle aspiration cytology smears is helpful in detecting microfilaria even in asymptomatic patients living in endemic zone which plays a significant role in recognition of disease and obviating severe manifestations of filariasis if treated in time
Enhancing Forage Production through Silvipastoral System in Arid Regions
Livestock based farming system makes significant contribution for livelihood security of farmers in arid zone of India. However, availability of fodder for livestock is not sufficient due to water scarcity and land degradation leading to low productivity of grazing land. The arid zones are less suitable for crop production due to inherent soil constraints like low water retentivity, sandy texture, shallow depth, occurrence of rocks and stones, however some grasses and tree species of forage value and economic importance can grow well and help in augmenting forage production. Silvipasture offers a sustainable land use system which increases overall productivity of land and makes efficient utilization of natural resources. Silvipastoral system has special significance in arid and semi-arid region (Tiwari et al., 1999)
A CLINICAL TRIAL OF AROGYA VARDHINI VATI AND LEKHANIYA MAHAKASHAYA IN THE MANAGEMENT OF OBESITY
Obesity is a condition in which there is an excessive accumulation of fat in the body which is a risk to health. The WHO now considers obesity to be a global epidemic and public health problem. Globally an estimated 300 million adults are now obese and many are overweight. A person with a BMI of 30 or more is generally considered obese. The problem is due to calorie imbalance resulting from an excessive food intake coupled with inadequate exercise. It is associated with increased mortality by predisposing to the development of important diseases like diabetes, hypertension, atherosclerosis, heart diseases, arthritis, infertility etc and diminishes the efficacy and happiness of affected. As per Ayurveda, Acharya charaka has counted Sthoulya under the eight varieties of impediments which are designated as Ninditapurusha. As Chikitsa sutra of Sthoulya, Lekhan karma is an important therapeutic measure said by Acharya charaka. Moreover, drugs of Arogya vardhini vati and Lekhaniya mahakashaya are most effective in the management of Sthoulya. To assess the effect of Lekhan karma, 20 patients were selected for this study from the OPD and IPD of Uttarakhand Ayurved University, Gurukul Campus Hospital, Haridwar. The effect of the therapy was assessed statically based on the performa prepared
THE SCOPE OF AYURVEDIC MEDICINE AND THERAPY IN THE MANAGMENT OF INFERTILITY
Infertility is described as an inability to conceive despite unprotective sex for duration of one year or more. Male, female or both can be a victim for this disorder. There may be many biological causes of infertility including some can be treated with medical or surgical intervention. Ayurveda consider this problem as a cause of deterioration of quality of four factors i.e., time of ovulation, female health in context of reproductive system, quality of sperm and ovum and female’s proper nutrition. There are different treatment methods and medicines used according to the deficit in male, female or in both. Vajikaran drugs like Ashwagandha, Madhuyasthi, Vidarikanda, Gokshura etc., are used in male fertility problems and Satavari, Punarnava, Dasmoola, Aloevera etc., used in female infertility problems. The purificatory procedures like Vamana, Virechana, Basti etc., are also found very effective to improve the quality and strength of required reproductive factors in both sexes. The effect of Uttar basti is also evidenced in different researches to treat female infertility
Status of the PANDA barrel DIRC
The PANDA experiment at the future Facility for Antiproton and Ion Research in Europe GmbH (FAIR) at GSI, Darmstadt will study fundamental questions of hadron physics and QCD using high-intensity cooled antiproton beams with momenta between 1.5 and 15 GeV/c. Hadronic PID in the barrel region of the PANDA detector will be provided by a DIRC (Detection of Internally Reflected Cherenkov light) counter. The design is based on the successful BABAR DIRC with several key improvements, such as fast photon timing and a compact imaging region. Detailed Monte Carlo simulation studies were performed for DIRC designs based on narrow bars or wide plates with a variety of focusing solutions. The performance of each design was characterized in terms of photon yield and single photon Cherenkov angle resolution and a maximum likelihood approach was used to determine the π/K separation. Selected design options were implemented in prototypes and tested with hadronic particle beams at GSI and CERN. This article describes the status of the design and R&D for the PANDA Barrel DIRC detector, with a focus on the performance of different DIRC designs in simulation and particle beams
Cross-sections for nuclide production in 56Fe target irradiated by 300, 500,750, 1000, 1500, and 2600 MeV protons compared with data on hydrogen target irradiation by 300, 500, 750, 1000, and 1500 MeV/nucleon 56Fe ions
Cross-sections for radioactive nuclide production in 56Fe(p,x) reactions at
300, 500, 750, 1000, 1500, and 2600 MeV were measured using the ITEP U-10
proton accelerator. In total, 221 independent and cumulative yields of products
of half-lives from 6.6 min to 312 days have been obtained via the
direct-spectrometry method. The measured data have been compared with the
experimental data obtained elsewhere by the direct and inverse kinematics
methods and with calculations by 15 codes, namely: MCNPX (INCL, CEM2k, BERTINI,
ISABEL), LAHET (BERTINI, ISABEL), CEM03 (.01, .G1, .S1), LAQGSM03 (.01, .G1,
>.S1), CASCADE-2004, LAHETO, and BRIEFF. Most of our data are in a good
agreement with the inverse kinematics results and disprove the results of some
earlier activation measurements that were quite different from the inverse
kinematics measurements. The most significant calculation-to-experiment
differences are observed in the yields of the A<30 light nuclei, indicating
that further improvements in nuclear reaction models are needed, and pointing
out as well to a necessity of more complete measurements of such reactions.Comment: 53 pages, 9 figures, 6 tables, only pdf file, submitted to Phys. Rev.
