Viable models with non-universal gaugino mediated supersymmetry breaking

Recently, extra dimensional SUSY GUT models have been proposed in which compactification of the extra dimension(s) leads to a breakdown of the gauge symmetry and/or supersymmetry. We examine a particular class of higher-dimensional models exhibiting supersymmetry and SU(5) or SO(10) GUT symmetry. SUSY breaking occurs on a hidden brane, and is communicated to the visible brane via gaugino mediation. Non-universal gaugino masses are developed at the compactification scale as a consequence of a restricted gauge symmetry on the hidden brane. In this case, the compactification scale is at or slightly below the GUT scale. We examine the parameter space of such models where gaugino masses are related due to a Pati-Salam symmetry on the hidden brane. We find limited but significant regions of model parameter space where a viable spectra of SUSY matter is generated. Our results are extended to the more general case of three independent gaugino masses; here we find that large parameter space regions open up for large values of the U(1) gaugino mass M_1. We also find the relic density of neutralinos for these models to be generally below expectations from cosmological observations, thus leaving room for hidden sector states to make up the bulk of cold dark matter. Finally, we evaluate the branching fraction BF(b -> s gamma) and muon anomalous magnetic moment a_\mu.Comment: 21 pages, 9 figure

Effects of Neutrino Inverse Seesaw Mechanism on the Sparticle Spectrum in CMSSM and NUHM2

We study the implications of the inverse seesaw mechanism (ISS) on the sparticle spectrum in the Constrained Minimal Supersymmetric Standard Model (CMSSM) and Non-Universal Higgs Model (NUHM2). Employing the maximal value of the Dirac Yukawa coupling involving the up type Higgs doublet provides a 2-3 GeV enhancement of the lightest CP-even Higgs boson mass. This effect permits one to have lighter colored sparticles in the CMSSM and NUHM2 scenarios with LSP neutralino, which can be tested at LHC14. We present a variety of LHC testable benchmark points with the desired LSP neutralino dark matter relic abundance.Comment: 18 pages, 10 figures and 2 table

Effective Methods of using of the Water Resources of Mountain Rivers with high turbidity

The article focuses on the solution methods of the problems arising from the rational use of the water resources of mountain rivers with high turbidity.Technical and operational indicators of water reservoirs constructed on mountain rivers characterised by high turbidity have been analysed and measures preventing stagnation of water reservoirs have been investigated.Issues related to the construction of a water reservoir outside the river bed and the prevention of stagnation of this water reservoir were investigated. The option of building a water receiving reservoir providing partial regulation and limpidity of the flow in the river valley was proposed. Hydraulic washing installation was proposed to remove sediments from the water reservoir equipped with the water tank. The working principle of washing installation with hydro-technical and hydraulic parameters are listed

Iatrogenic superficial external pudendal artery pseudoaneurysm: Treatment with doppler us-guided compression

Pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. As a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. Iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. Here we report a case of iatrogenic superficial external pudendal artery (SEPA) pseudoaneurysm following cardiac catheterization, which was diagnosed with Doppler ultrasound (US) and multidetector computed tomographic angiography (MDCTA) before Doppler US-guided compression therapy. To the best of our knowledge, iatrogenic SEPA pseudoaneurysm, which is an unusual vessel location for pseudoaneurysm occurrence, has not been reported in the literature. In patients in whom anticoagulant-thrombolytic therapy or therapeutic catheterization with larger sized sheath is planned, determination of the precise localization of arterial puncture site is important for the prevention of iatrogenic pseudoaneurysm development. Arterial puncture guided with Doppler US might reduce complications. When suspected, MDCTA is useful in the diagnosis and demonstration of iatrogenic pseudoaneurysms. Treatment of US-guided compression should be the first choice for iatrogenic pseudoaneurysms. Interventional radiologists and cardiologists should have enough experience about the catheterization complications and their treatment in order to decrease the morbidity and mortality related to the intervention

Features of geology and composition of rocks from the alkaline-gabbroid University massif (NE Kuznetsk Alatau ridge, Siberia)

This paper discusses specifics of petrography and structural tectonic position of the alkaline-gabbroic University massif, which is a sort of analogue of the Kiya-Shaltyr deposit of nepheline ores in this area that was very slightly eroded. In this work, we will also present new precise analytical data on rare and trace element distribution in major intrusive phases of this geological object, and also isotope dating on the basis of Sm-Nd method

Immunodiffusion assayasa method ofbovineleukosispost-mortem diagnosis

New method of post-mortem diagnosis of bovine leukosis is proposed and it involves use of agar gel immunodiffusion assay. The proposed method allows for the detection of antibodies against bovine leukemia virus (BLV) antigen located in the muscle and tissue fluids (plasma and lymph) of meat and offal. Post-mortem sampling was performed by dragging sterile cotton swabs across different parts of carcass and organs of both animals known to be seronegative and animals not tested alive. The collected samples and accompanied documents were submitted to the laboratory. 0.5–0.7 ml of isotonic solution (0.85% sodium chloride solution) were added to the tube with the swabs and the tube was left for 3–5 hours at 18–26 °C until homogenous substance formation. The tube was occasionally shaken so that BLV antibodies moved to the normal saline solution for further immunodiffusion assay. The assay results were visually recorded by detection of precipitation lines. Testing of 175 samples collected from animals not serologically tested for bovine leukosis before slaughter demonstrated five positive results (2.9%). Immunodiffusion assay of the tissue (lymphatic) fluid swabs collected from 148 animals, declared BLV seronegative alive in the veterinary certificates, demonstrated negative results. Therefore, along with autopsy, histological, molecular and genetic methods the immunodiffusion assay can be one of the tools for post-mortem diagnosis of bovine leukosis

Bovine leukosis incidence in Republic of Dagestan in 2021

Results of epizootological analysis of data on bovine leucosis (BL) incidence in the Republic of Dagestan in 2021 are reported. Bovine blood was diagnostically tested for leukosis in 32 veterinary laboratories and diagnostic offices including SBI RD Republican Veterinary Laboratory. 720,489 sera were serologically tested and 7,188 (1.0%) samples were serologically positive for bovine leukaemia virus (BLV). Among the infected animals, 527 ones were subjected to haematologic testing. Persistent leukocytosis was reported in 153 (29.03%) blood samples of haematologically tested BL diseased cattle. Statistical analysis of BLV prevalence in the republic was performed for 41 Raions and 8 municipalities. High percentage of BLV infection in the animal population was reported in fourteen Raions: Kumtorkalinsky (5.8%), Gunibsky (5.3%), Tarumovsky (3.3%), Karabudakhentsky (2.9%), Akhvakhsky (2.0%), Kizlyarsky (1.8%), Charodinsky (1.7%), Kazbekovsky (1.6%), Babayurtovsky (1.5%), Tlyaratinsky (1.1%), Dakhadayevsky (1.04%), Sergokalinsky (1.02%), Novolaksky (1.0%), Shamilsky (1.0%), and in four municipalities: Makhachkala (2.0%), Izberbash (1.14%), Khasavyurt (1,1%) and Yuzhno-Sukhokumsk (1.0%). In 21 Raions and two municipalities, BLV seropositivity was below 1.0%. No BLV infected animals were detected in the Agulsky, Akhtynsky, Dokuzparinsky, Magaramkentsky, Khivsky, Suleiman-Stalsky Raions and in Derbent and Dagestanskiye Ogni municipalities. Studies of BLV prevalence in 2015–2021 demonstrated that the highest level of the animal infection was reported in 2015 (13.9%) and the lowest – in 2021 (1.0%). However, the number of animals serologically tested in 2021 exceeded the number of animals tested over the whole study period. Therefore, the Republic of Dagestan remains BL infected region
