Effect of Various Levels of Nitrogen, Phosphorus and Potash on the Yield of French Bean

The experiment was conducted at the farm of Agricultural Research Station, Baffa (Mansehra) during August 2014 to monitor the effect of various levels of fertilizer treatments on plant height, number of branches plant-1, pod length, pod weight and pod yield of French bean variety (paulista). The experimental results revealed that that all the fertilizer treatments increased the plant height, number of branches plant-1, pod length, pod weight and pod yield of French bean significantly over control treatment. Maximum plant height (39.03 cm), number of branches plant-1(18.25), pod length (14.10 cm),  pod weight (5.37 gm) and pod yield (8.26 t ha-1) were recorded in the treatment receiving 120 kg N, 90 kg P2O5 and 90 kg K2O ha-1. The economics of fertilizers were also worked out on the basis of current market prices and it was found that use of fertilizer was profitable. The cost benefit ratio ranged between 4.90. to 6.05.

Effect of Sowing Dates on the Yield and Seed Production of Okra Cultivars in Mansehra

To monitor the effect of different sowing dates on the yield and seed production of okra cultivars, an experiment was conducted at Agricultural Research Station, Baffa Mansehra during 2014. Six cultivars of okra i.e. Irka, Sabz Pari, Pusa Green, Pusa Sawani, Sarhad Green and Green Star were sown on three different sowing dates with 15 days interval i.e. 15th March, 30th March and 14th April, 2014. Maximum number of pods plant-1 (32.12), pod length (11.12 cm), pod diameter (1.54 cm), pod weight (15.24 gm), plant height (184.28 cm), pod yield (16.24 t ha-1), seed yield (1601.92 kg ha-1) and 1000-seed weight (86.92 gm) were recorded in cultivars, sown on 30th March, 2014. Maximum number of pods plant-1 (32.75), pod length (11.57 cm), pod diameter (1.67 cm), pod weight (16.04 gm), plant height (187.17 cm), pod yield (17.50 t ha-1), seed yield (1735.00 kg ha-1) and 1000-seed weight (89.32 gm) were recorded in cultivar Sabz Pari. Sowing of okra cultivar Sabz Pari on 30th March is recommended for realizing maximum fresh pod and seed yields under the agro-climatic conditions of Mansehra District. Key words: okra, cultivar, sowing date, pod yield, seed weight

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for supersymmetry in the multijet and missing transverse momentum final state in pp collisions at 13 TeV

A search for new physics is performed based on all-hadronic events with large missing transverse momentum produced in proton-proton collisions at sqrt(s)=13 TeV. The data sample, corresponding to an integrated luminosity of 2.3 inverse femtobarns, was collected with the CMS detector at the CERN LHC in 2015. The data are examined in search regions of jet multiplicity, tagged bottom quark jet multiplicity, missing transverse momentum, and the scalar sum of jet transverse momenta. The observed numbers of events in all search regions are found to be consistent with the expectations from standard model processes. Exclusion limits are presented for simplified supersymmetric models of gluino pair production. Depending on the assumed gluino decay mechanism, and for a massless, weakly interacting, lightest neutralino, lower limits on the gluino mass from 1440 to 1600 GeV are obtained, significantly extending previous limits
