Utjecaj tjelesne kondicije na metaboličke serumske pokazatelje u burske koze prije i nakon jarenja

In goats, during the puerperal period, a lack of energy is one of the most frequent causes of sudden metabolic changes and the consequent reproductive disorders. The aim of our study was to assess the influence of the body condition on the serum profile of metabolites such as: total proteins (TP), albumin (ALB), triglycerides (TG), cholesterol (CHOL), glucose (GLU) and β-hydroxybutirate (BHB) in Boer goats during late pregnancy (Day 120), at parturition (Day 0) as well as on Days 30 and 60 after parturition. A total of 15 female Boer goats (does), from a commercial farm in north western Croatia were used. The body condition status of the goats was established using the standard protocol for scoring. Based on the body condition score (BCS), each doe was categorized into one of three groups: group 1 (n = 5) or obese does with BCS ≥3.50-5.00, group 2 (n = 5) or medium does with BCS ≥2.75<3.50 and group 3 (n = 5) or thin does with BCS <2.75. The concentrations of serum TP, ALB, TG, CHOL, GLU and BHB were measured spectrophotometrically. On Day 120 of pregnancy the level of TG was significantly higher (P<0.05) in the obese does than the medium does. The levels of TP or CHOL were significantly higher (P<0.05) in the obese than in the thin does on Day 30 and Day 60, respectively, following parturition. The recorded changes in the metabolites tested could be of significance for monitoring the metabolic status of goats during intensive production, and of practical interest for preventing/controlling economic losses in goat breeding.U koze tijekom puerperija nedostatak energije predstavlja jedan od najčešćih uzroka iznenadnih metaboličkih promjena i posljedičnih reprodukcijskih poremećaja. Cilj našeg istraživanja bio je procijeniti utjecaj tjelesne kondicije na serumske metabolite kao što su: ukupni proteini (UP), albumin (ALB), trigliceridi (TG), kolesterol (CHOL), glukoza (GLU) i β-hidroksimaslačna kiselina (BHB) u burskih koza tijekom kasne gravidnosti (120. dan), porođaja (0. dan) kao i na 30. i 60. dan nakon porođaja. Ukupno je korišteno 15 burskih koza iz komercijalne farme u sjeverozapadnoj Hrvatskoj. Status tjelesne kondicije (engl. body condition score, BCS) koza utvrđen je uporabom standardnog protokola za ocjenu. Na temelju ocjene BCS svaka je koza kategorizirana u jednu od 3 skupine od po 5 životinja u svakoj: 1. skupina - pretile (BCS≥3,50-5,00), 2. skupina - srednjeg gojnog stanja (BCS≥2,75-3,50) i 3. skupina - mršave (BCS≤2,75). Koncentracije serumskih UP, ALB, TG, CHOL, GLU i BHB bile su određivane spektrofotometrijski. Na 120. dan gravidnosti razina TG bila je značajno viša (P<0,05) u pretilih koza nego u koza srednjeg gojnog stanja. Razine UP i CHOL bile su značajno više (P<0,05) u pretilih nego u mršavih koza 30., odnosno 60. dana nakon porođaja. Zabilježene promjene u istraživanih metabolita mogle bi biti od značenja za praćenje metaboličkog statusa koza tijekom intenzivne proizvodnje, a mogle bi biti i od praktične vrijednosti za prevenciju i kontrolu gospodarskih gubitaka u uzgoju koza

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 heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe

Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).
