Aortic arch tortuosity with PHACE syndrome : a rare case scenario

PHACE syndrome is a rare neurocutaneous disorder characterised by an association of infantile haemangiomas with structural anomalies of brain, cerebral vasculature, eye, aorta and chest wall.1 Coarctation of aorta (COA) is most the common cardiac anomaly reported in PHACE syndrome. COA or interrupted aortic arch in PHACE is unique and complex both in location and character compared to the typical coarctation anatomy. Arterial tortuosity of the cerebral vasculature has been well described in literature in PHACE syndrome. We present a rare case of tortuous aortic arch continuing as descending aorta in an infant with PHACE syndrome.peer-reviewe

Search for dark mesons decaying to top and bottom quarks in proton-proton collisions at √s = 13 TeV with the ATLAS detector

A search for dark mesons originating from strongly-coupled, SU(2) dark favor symmetry conserving models and decaying gaugephobically to pure Standard Model final states containing top and bottom quarks is presented. The search targets fully hadronic final states and final states with exactly one electron or muon and multiple jets. The analyzed data sample corresponds to an integrated luminosity of 140 fb−1 of proton-proton collisions collected at √s = 13 TeV with the ATLAS detector at the Large Hadron Collider. No significant excess over the Standard Model background expectation is observed and the results are used to set the first direct constraints on this type of model. The two-dimensional signal space of dark pion masses mπD and dark rho-meson masses mρD is scanned. For mπD /mρD = 0.45, dark pions with masses mπD < 940 GeV are excluded at the 95% CL, while for mπD /mρD = 0.25 masses mπD < 740 GeV are excluded

Combination of searches for Higgs boson decays into a photon and a massless dark photon using pp collisions at √s = 13 TeV with the ATLAS detector

A combination of searches for Higgs boson decays into a visible photon and a massless dark photon (H → γγd) is presented using 139 fb−1 of proton-proton collision data at a centre-of-mass energy of √s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The observed (expected) 95% confidence level upper limit on the Standard Model Higgs boson decay branching ratio is determined to be B(H → γγd) < 1.3% (1.5)%. The search is also sensitive to higher-mass Higgs bosons decaying into the same final state. The observed (expected) 95% confidence level limit on the cross-section times branching ratio ranges from 16 fb (20 fb) for mH = 400 GeV to 1.0 fb (1.5 fb) for mH = 3 TeV. Results are also interpreted in the context of a minimal simplified model

Impact of fire on mechanical properties of concrete containing marble waste

Concrete mixes with 75% fraction of coarse aggregate obtained from marble mining waste and 25% with conventional coarse aggregate were designed by particle packing density approach. The variations in mechanical properties of concrete exposed to real standard fire were investigated in a temperature range of 200–800 °C. Properties like compressive strength, ultra-sonic pulse velocity values, loss of mass in concrete specimens did not show any adverse impact at elevated temperature up to 400 °C. Water absorption in marble concrete mixes was less than that of control mixes. In all it was concluded that the mechanical properties of concrete mixes produced from marble waste were found to be satisfactory after fire exposure up to 400 °C. Concrete started deteriorating increase in temperature beyond this value. Keywords: Concrete, Marble waste, Fire, Mechanical propertie

Impact of marble waste as coarse aggregate on properties of lean cement concrete

Marble industry produces large amount of waste during mining and processing stages. This waste is dumped on to open land which creates a lot of environmental problems. The main objective of this study was utilization of marble waste as a replacement for conventional natural coarse aggregate in concrete. Experimental investigations were carried out to examine the feasibility of use of marble waste as a coarse aggregate in concrete. Conventional natural coarse aggregate was replaced by marble aggregate in different percentages 0–100% by weight. The concrete formulations were prepared with a constant water–cement ratio 0.60. It was observed that workability of concrete mixes containing marble aggregate was 14% more than that of control concrete. The average compressive strength of all the concrete mixes containing marble aggregate increased by 40% and 18% at 7 and 28 days, respectively

Not AvailableThe testes are normally in the scrotum or just after birth in most of the domestic livestock. The incidence of cryptorchidism i.e. failure to descend of one or both testes is higher in horses followed by pigs and least in cattle (Arthur et al., 1989). In camels the development of scrotal sac and descent of testes occurs after birth between 66 and 296 days and this process has been reported to be influenced by the ambient temperature (Bissa et al., 1988). Incidence of cryptorchidism was reported by Kohli and Verma (1981). The cryptorchidism may occur due to disordered endocrine secretion and could also be due to genetic abnormality (Arthur et al., loc. cit.). A case of cryptorhid camel belonging to Bikaneri breed of India is reported in this article. This animal was born at N.R.C. on Camel. The scrotal sac of the cryptorchid camel was rudimentary without testicles. It exhibited symptoms of rut viz. restlessness, aggressiveness, grinding of teeth, gurgling sound, ejection and blowing of soft palate oozing of acrid dark brown secretions from the poll glands during breeding season after attaining puberty and also mounted females for mating. Attempts to collect semen in artificial vagina from the animal were successful. The camel exhibited normal libido. During breeding season ejaculation time was 4.0 ? 0.5 min. which was almost similar to ejaculation time reported by Rai et al., (1988) for normal camel studs. In all 8 semen samples were collected. The volume of ejaculates varied from 3.7 to 4.0 ml. The semen was grayish in color, thin viscid with mild gel. The pH varied from 8.0 to 8.5. The microscopic examination revealed azoospermia and the volume was comparatively lesser than in the breeding season (average 2.2 ml). The sexual behaviour was comparable to the behaviour of normal camel studs during non breeding season reported by rai et al., (1996).Not Availabl
