Primary Amoebic (Naegleria fowleri) Meningoencephalitis Presenting as Status Epilepticus

Primary amebic meningoencephalitis (PAM) is a rare entity. Usual presenting features are fever, headache and seizures with meningeal signs and this disease carries high mortality rate. We present a case report of PAM presenting as status epilepticus

Hilbert-Schmidt Operators vs. Integrable Systems of Elliptic Calogero-Moser Type III. The Heun Case

The Heun equation can be rewritten as an eigenvalue equation for an ordinary differential operator of the form $-d^2/dx^2+V(g;x)$, where the potential is an elliptic function depending on a coupling vector $g\in{\mathbb R}^4$. Alternatively, this operator arises from the $BC_1$ specialization of the $BC_N$ elliptic nonrelativistic Calogero-Moser system (a.k.a. the Inozemtsev system). Under suitable restrictions on the elliptic periods and on $g$, we associate to this operator a self-adjoint operator $H(g)$ on the Hilbert space ${\mathcal H}=L^2([0,\omega_1],dx)$, where $2\omega_1$ is the real period of $V(g;x)$. For this association and a further analysis of $H(g)$, a certain Hilbert-Schmidt operator ${\mathcal I}(g)$ on ${\mathcal H}$ plays a critical role. In particular, using the intimate relation of $H(g)$ and ${\mathcal I}(g)$, we obtain a remarkable spectral invariance: In terms of a coupling vector $c\in{\mathbb R}^4$ that depends linearly on $g$, the spectrum of $H(g(c))$ is invariant under arbitrary permutations $\sigma(c)$, $\sigma\in S_4$

Uncertainties in nuclear transition matrix elements for neutrinoless ββ\beta \beta decay II: the heavy Majorana neutrino mass mechanism

Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the uncertainties in the nuclear transition matrix elements $M_{N}^{(0\nu)}$ due to the exchange of heavy Majorana neutrino for the $0^{+}\rightarrow 0^{+}$ transition of neutrinoless double beta decay of $^{94}$Zr, $^{96}$Zr, $^{98}$Mo, $^{100}$Mo, $^{104}$Ru, $^{110}$Pd, $^{128,130}$Te and $^{150}$Nd isotopes in the PHFB model are estimated to be around 25%. Excluding the nuclear transition matrix elements calculated with Miller-Spenser parametrization of Jastrow short range correlations, the uncertainties are found to be 10%-15% smaller

Bioefficacy of some insecticides against shoot and fruit borer, Leucinodes orbonalis Guenee on brinjal under Hisar agro-climatic conditions during kharif season

A field experiment was conducted to study the bioefficacy of some insecticides against Leucinodes orbonalis during kharif season of 2014 on brinjal var. BR-112 at Entomology Research Area of CCS Haryana Agricultural University, Hisar. Five foliar sprays of insecticides viz., cypermethrin 25EC @ 43.75 g a.i/ ha, fenvalerate 20EC @40 g a.i/ ha, deltamethrin 2.8EC @ 14 g a.i/ ha, chlorpyriphos 20EC @ 200 g a.i/ ha, Prempt 20EC @ 150 g a.i/ ha, malathion 50EC @ 250 g a.i/ ha and Nimbecidine 0.03% @ 3 ml/l were evaluated and it was found that all the insecticides proved significantly superior (at 5% level) to control (untreated) in reducing the damage of shoot and fruit borer in brinjal. Among all, deltamethrin proved most effective in reducing shoot damage (60.40%) and fruit damage, on number basis (88.87%) and weight basis (88.89%) over control. Deltamethrin recorded the highest marketable fruit yield of 132.27q/ha and lowest was found in case of Nimbecidine (33.53 q/ha). Highest (1:8.7) cost to benefit ratio was recorded in deltamethrin followed by fenvalerate (1:8.5), cypermethrin (1:6.5), chlorpyriphos (1:4.5), Prempt (1:1.9), malathion (1:0.6) and Nimbecidine (1: -0.3). From these findings, it was revealed that synthetic pyretheroids being the most effective and economic over other insecticides, may be incorporated in IPM practices followed against brinjal shoot and fruit borer

Undiagnosed Patent Foramen Ovale Presenting as Retinal Artery Occlusion—An Emerging Association

Purpose. To report patent foramen ovale (PFO) as the cause of retinal artery occlusion in a young and previously fit male and discuss the appropriate medical and surgical management options. Methods. Interventional case report with serial fundus photographs of an 18-year-old male presenting to the eye casualty with sudden onset left visual loss. Results. Visual acuities were 6/24 left and 6/4 right with a left afferent pupillary defect. Slitlamp examination confirmed a left hemiretinal artery occlusion and subsequent cardiology review with transoesophageal echocardiography revealed patent foramen ovale which was closed surgically. Conclusions. PFO is not uncommon and is often covert but predisposes individuals to embolic events. These events may be ophthalmic with visual sequelae and so ophthalmologists, physicians, and other healthcare personnel should be aware of this important and emerging association

New limit for the half-life of double beta decay of 94^{94}Zr to the first excited state of 94^{94}Mo

Neutrinoless Double Beta Decay is a phenomenon of fundamental interest in particle physics. The decay rates of double beta decay transitions to the excited states can provide input for Nuclear Transition Matrix Element calculations for the relevant two neutrino double beta decay process. It can be useful as supplementary information for the calculation of Nuclear Transition Matrix Element for the neutrinoless double beta decay process. In the present work, double beta decay of $^{94}$Zr to the $2^{+}_{1}$ excited state of $^{94}$Mo at 871.1 keV is studied using a low background $\sim$ 230 cm$^3$ HPGe detector. No evidence of this decay was found with a 232 g.y exposure of natural Zirconium. The lower half-life limit obtained for the double beta decay of $\rm^{94}Zr$ to the $2^{+}_{1}$ excited state of $\rm^{94}Mo$ is $T_{1/2} (0\nu + 2\nu)> 3.4 \times 10^{19}$ y at 90% C.L., an improvement by a factor of $\sim$ 4 over the existing experimental limit at 90\% C.L. The sensitivity is estimated to be $T_{1/2} (0\nu + 2\nu) > 2.0\times10^{19}$ y at 90% C.L. using the Feldman-Cousins method.Comment: 11 pages, 7 figures, Accepted in Eur. Phys. J.
