A hatvani Széchenyi Zsigmond Vadászati Múzeum = The Széchenyi Zsigmond Hunting Museum in Hatvan

Th e opening of the Széchenyi Zsigmond Hunting Museum in the baroque Grassalkovich Mansion in Hatvan, Hungary was the realisation of a 100-year-old dream. Th e Hungarian hunting and fi shing culture and traditions are shown through nine exhibitions on three floors: game species of the Carpathian Basin, clothing, music, art pieces etc. related to or inspired by hunting. Th e museum uniquely combines traditional elements like display cabinets with interactive computers, which allow the visitor a playful learning experience and thorough understanding of the role of hunting in our modern, mostly urbanised society. In the park of the castle, in two modern buildings, the so-called ‘Adventure Place’ provides the chance for everyone to try shooting with laser guns and bowhunting, which gives an insight into the practices of modern hunting.

Exact ground states of a staggered supersymmetric model for lattice fermions

We study a supersymmetric model for strongly interacting lattice fermions in the presence of a staggering parameter. The staggering is introduced as a tunable parameter in the manifestly supersymmetric Hamiltonian. We obtain analytic expressions for the ground states in the limit of small and large staggering for the model on the class of doubly decorated lattices. On this type of lattice there are two ground states, each with a different density. In one limit we find these ground states to be a simple Wigner crystal and a valence bond solid (VBS) state. In the other limit we find two types of quantum liquids. As a special case, we investigate the quantum liquid state on the one dimensional chain in detail. It is characterized by a massless kink that separates two types of order.Comment: 21 pages, 6 figures, v2: largely rewritten version with more emphasis on physical interpretatio

Light-induced instabilities in photo-oriented liquid crystal cells

In a planar liquid crystal sample sandwiched between a photosensitive and a reference plate instabilities occurred, when the cell was illuminated from the reference side. The instabilities were induced both by polarized white light source and monochromatic laser beams. Static and dynamic regimes were found; for laser irradiation dynamic instability was found only in a range of polarization directions. A model, developed for monochromatic excitation, predicts that at certain thicknesses dynamic instability is forbidden. Experiments on a wedge-like cell confirmed this conclusion.Comment: to appear in Mol. Cryst. Liq. Crys

Checklist of the Mammals of Iraq (Chordata: Mammalia)

A checklist of the mammals of Iraq including their current status and geographical distribution is provided. Data were collected from literature and combined with field observations obtained during 2013–2014. The checklist comprises 93 species of wild mammals occurring in Iraq and belonging to eight orders, 28 families, and 65 genera. The status and distribution of three Erinaceomorphs, three Soricomorphs, 20 Bats, 23 Carnivores, eight Artiodactyls, two Lagomorphs, 28 Rodents, and six Cetaceans are reported. The checklist includes 24 species evaluated by the International Union for the Conservation of Nature and Natural Resources: one was listed as Extinct, one as Critically Endangered, four as Endangered, eight as Vulnerable, seven as Near Threatened, and three as Data Deficient. One subspecies of carnivores (Smooth-coated Otter Lutrogale perspicillata maxwelli) and one rodent species (Long-tailed Nesokia Nesokia bunnii) endemic to Mesopotamian marshlands were highlighted as taxa with conservation priority to Iraq. We also focused on main threats to the most common wild mammals with special attention to impacts of illegal hunting and poaching

Phase behaviors of binary mixtures composed of banana-shaped and calamitic mesogens

In this work, five mixtures with different concentrations of banana-shaped and calamitic compounds have been prepared and subsequently studied by polarizing optical microscopy, differential scanning calorimetry, and X-ray diffraction on non-oriented samples. The phase sequences and molecular parameters of the binary systems are presented

Comparison of biological and chemical properties of arable and pasture Solonetz soils

Soil samples were collected from salt-affected soils (Solonetz) under different land uses, namely arable (SnA) and pasture (SnP), to investigate the effects of land use on microbiological [basal soil respiration (BSR), microbial biomass carbon (MBC), dehydrogenase activity (DHA) and phosphatase activity] and chemical properties [organic carbon (OC), humic ratio (E4/E6), pH, electrical conductivity (EC), ammonium nitrogen (NH4-N), nitrate nitrogen (NO3-N), available forms of phosphorus (P2O5), potassium (K2O), calcium (Ca2+), magnesium (Mg2+), sodium (Na+)] and on the moisture content. The results showed that the two sites, SnA and SnP, were statistically different from each other for all the microbiological and chemical parameters investigated except Na+ and moisture content. Higher values of MBC (575.67 μg g-1), BSR (9.71 μg CO2 g-1 soil h-1), DHA (332.76 μg formazan g-1 day-1) and phosphatase activity (0.161 μmol PNP g-1 hr-1) were observed for the SnP soil. Great heterogeneity was found in SnP in terms of microbiological properties, whereas the SnA plots showed more homogeneous microbiological activity due to ploughing. 75.34% of variance was explained by principal component one (PC1), which significantly separated SnA and SnP, especially on the basis of soil MBC and P2O5. Moreover, it was concluded that the pasture land (SnP) was microbiologically more active than arable land (SnA) among the Hungarian salt-affected soils investigated
