Vanishing corrections on the intermediate scale and implications for unification of forces

In two-step breaking of a class of grand unified theories including SO(10),we prove a theorem showing that the scale $M_I$ where the Pati-Salam gauge symmetry with parity breaks down to the standard gauge group,has vanishing corrections due to all sources emerging from higher scales $\mu >M_I$ such as the one-loop and all higher loop effects,the GUT-threshold,gravitational smearing,and string threshold effects. Implications of such a scale for the unification of gauge couplings with small Majorana neutrino masses are discussed.In string inspired SO(10) we show that $M_I \simeq 5\times 10^{12}$,needed for neutrino masses,with the GUT scale $M_U \simeq M_{str}$ can be realized provided certain particle states in the predicted spectum are light.Comment: 21 pages, Late

Sistem Pendukung Keputusan Penentuan Penilaian Karyawan Berprestasi Menggunakan Metode Saw dan Ahp

STAI Ibnu Rusyd kotabumi adalah sebuah perguruan tinggi yang selalu berupaya dalam peningkatan mutu internal secara berkelanjutan agar dapat bersaing dengan perguruan tinggi swasta lain. Salah satu upaya yang dilakukan adalah dengan melakukan penilaian terhadap karyawan. Penilaian tersebut dilakukan untuk mengetahui karyawan berprestasi, akan tetapi penilaian karyawan yang dilakukan selama ini masih menggunakan metode manual. Berdasarkan kondisi tersebut maka diperlukan adanya metode yang tepat dan akurat dalam mengelola data penilaian karyawan.Menggunakan metode Simple Additive Weighting (SAW) dengan Analytic Hierarchy Process (AHP) di hitung nilai masing-masing karyawan yang melibatkan beberapa kriteria yaitu kriteria komitmen, manajemen, kerjasama dan hasil kerja setelah perhitungan dilakukan maka ditentukan manakah metode yang paling tepat.Dari penelitian ini dapat disimpulkan bahwa metode Analytic Hierarchy Process (AHP) lebih tepat untuk studi kasus pemilihan karyawan berprestasi karena pemilihan karyawan berprestasi ini melibatkan banyak subkriteria, dimana AHP dianggap tepat untuk mewakili pemikiranalamiah yang cenderung mengelompokkan elemen sistemke level-level yang berbeda dari masing-masing level berisi elemen yang serupa dan juga menyediakan skala pengukuran

Persistent Mullerian duct syndrome: the hidden normal or abnormal anatomy and the value of laparoscopy

Persistent Mullerian duct syndrome (PMDS) is a rare disorder of male sexual development. It is characterized by the presence of a uterus, fallopian tubes, and upper vagina in an otherwise phenotypically and genotypically normal male. This malformation is usually an incidental finding during the operative treatment of other more common abnormalities such as inguinal hernia or undescended testes. Not uncommonly, it is seen in association with transverse testicular ectopia. This report describes a case of PMDS in association with transverse testicular ectopia diagnosed at the time of laparoscopy for undescended testes. Physicians caring for these patients should be aware of this and surgeons should be familiar with the different surgical options. PMDS should be considered in all cases of bilateral undescended testes. Aspects of diagnosis and management are also discussed. Keywords: inguinal hernia, laparoscopy, persistent mullerian duct syndrome, transverse testicular ectopia, undescended teste

New Uncertainties in QCD-QED Rescaling Factors using Quadrature Method

In this paper we briefly outline the quadrature method for estimating uncertainties in a function of several variables and apply it to estimate the numerical uncertainties in QCD-QED rescaling factors. We employ here the one-loop order in QED and three-loop order in QCD evolution equations of fermion mass renormalization. Our present calculations are found to be new and also reliable compared to the earlier values employed by various authors.Comment: 14 page

Petrographical Characteristics of Bituminous Coal from Jharia Coalfield India: It's Implication on Coal Bed Methane Potentiality

AbstractThe ever increasing demand for energy resources forces India to hunt for alternate resources like coal bed methane (CBM) and shale gas. CBM is considered as clean source however its occurrence and extraction poses many challenges. The challenges vary widely across region, depth of occurrence, rank of coal, feature of cover etc. So, its characterization is important for successful extraction. The present paper discussed about the Petrographic study of coal and its correlation with different parameters that influence the recovery of CBM. Sample from deep seated coal field have been evaluated with respect to its proximate and ultimate parameters. Mutual correlations have also been developed statistically among parameters

Breeding, genetics, and genomics approaches for improving Fusarium Wilt resistance in major grain legumes

Fusarium wilt (FW) disease is the key constraint to grain legume production worldwide. The projected climate change is likely to exacerbate the current scenario. Of the various plant protection measures, genetic improvement of the disease resistance of crop cultivars remains the most economic, straightforward and environmental-friendly option to mitigate the risk. We begin with a brief recap of the classical genetic efforts that provided first insights into the genetic determinants controlling plant response to different races of FW pathogen in grain legumes. Subsequent technological breakthroughs like sequencing technologies have enhanced our understanding of the genetic basis of both plant resistance and pathogenicity. We present noteworthy examples of targeted improvement of plant resistance using genomics-assisted approaches. In parallel, modern functional genomic tools like RNA-seq are playing a greater role in illuminating the various aspects of plant-pathogen interaction. Further, proteomics and metabolomics have also been leveraged in recent years to reveal molecular players and various signaling pathways and complex networks participating in host-pathogen interaction. Finally, we present a perspective on the challenges and limitations of high-throughput phenotyping and emerging breeding approaches to expeditiously develop FW-resistant cultivars under the changing climate
