Published: May 2019

The yielding capacity and quality parameters of 11 maize hybrids were studied in 2011 on calcareous chernozem soil in a 25-year long-term fertilization experiment in the control (without fertilization), in the base treatment of N 40 kg ha-1, P2O5 25 kg ha-1, K2O 30 kg ha-1 and in five treatments which were the multiplied doses of the base treatment. The N fertilizer was applied in the autumn and in the spring, while P and K fertilizers were applied in the autumn.The sowing time was 17–18 April, the time of harvest was 8 October. The 30-year average of precipitation (April–Sept) was 345.1 mm, the amount of precipitation did not differ greatly from that, however, its distribution was very unfavourable.It was found that the largest yield increment (as compared to the control) was in the treatment N 40 kg ha-1, P2O5 25 kg ha-1, K2O 30 kg ha-1 in the long-term experiment. The largest yields were obtained for the hybrids P9494, PR37N01 and PR35F38 (13.64–13.71 t ha-1). Due to the dry period at the end of the summer – beginning of autumn, the grain moisture content at harvest was favourably low, 12–18% depending on the treatment and the growing season.
The N fertilization significantly increased the protein content of the kernel, but the starch content of the kernel decreased (significantly in several cases) with increasing fertilizer doses and yields as compared with the control.The highest protein content was measured in hybrids GK Boglár and Szegedi 386. The oil content was above 4% for GK Boglár, but the two hybrids were not among the best yielding hybrids in spite of their good inner content. The starch content was around 75 % without fertilization, it decreased with fertilization.For the tested hybrids, the fertilizer dose N 120 kg ha-1, P2O5 75 kg ha-1, K2O 90 kg ha-1 can be recommended with respect to efficacy and environmental considerations.

Banjarbaru, khususnya daerah kelurahan Cempaka merupakan salah satu daerah penghasil karet di Kalimantan Selatan. Kebanyakan pertanian karet di daerah tersebut merupakan milik perorangan. Berdasarkan data Statistik Perkebunan Indonesia tahun 2013 jumlah petani karet di daerah Banjarbaru sekitar 672 orang dengan luas tanah 648 Ha. Selama ini hanya getah dari tanaman karet yang dimanfaatkan dan biji karet yang melimpah dari pohon karet hanya sebagian kecil dimanfaatkan sebagai bibit dan sisanya di buang begitu saja. Biji karet mentah mengandung racun Sianida dengan kadar >50 ppm. Namun dengan melakukan teknik yang benar, racun sianida dalam biji karet dapat direduksi hingga batas aman. Pada kegiatan Iptek bagi Masyarakat, biji karet yang telah direduksi kandungan racun sianidanya kemudian diolah dalam berbagai olahan, yaitu opak/kerupuk dengan berbagai rasa. Hasil uji laboratorium, dalam 10 gr kerupuk biji karet, kandungan sianida dapat diminimalis hingga 0,27 ppm dengan kandungan gizi Kabohidrat 35,48% dan protein 3,06 %.

Nonlinear Development of Electron Heat Flux Instability: Particle in Cell Simulation
Authors: Lee Sang-Yun , Lee Ensang , Yoon Peter H. 
Published: May 2019

Abstract
Finite heat flux often exists in space and astrophysical plasmas, which can be a free energy source for heat flux instability. The solar wind is a well-known example of such plasmas and a number of previous studies have investigated the characteristics of heat flux instability in the context of solar wind. In the literature there exists some uncertainties regarding the properties of heat flux instability. While some linear theories predict the association of the heat flux instability with right-hand polarized whistler waves, other studies argue for left-hand polarized unstable modes. The present study investigates the nonlinear development of initially unstable left-hand heat flux mode by means of particle-in-cell simulation. It is found that while the early phase is characterized by the left-hand polarization, in agreement with linear theory, as the wave amplitude becomes high and the instability enters the nonlinear phase, the dominant wave mode gradually switches over to the right-hand polarized waves. Such a behavior is related to the pitch angle scattering of the heat flux carrying electrons by nonlinear interaction with large-amplitude waves. The present study shows that the heat flux instability generally requires nonlinear treatment such that characterizing its behavior with linear theories may not always be adequate.
Massive Stellar Mergers as Precursors of Hydrogen-rich Pulsational Pair Instability Supernovae
Authors: Vigna-Gómez Alejandro , Justham Stephen , Mandel Ilya , de Mink Selma E. , Podsiadlowski Philipp 
Published: May 2019

Abstract
Interactions between massive stars in binaries are thought to be responsible for much of the observed diversity of supernovae. As surveys probe rarer populations of events, we should expect to see supernovae arising from increasingly uncommon progenitor channels. Here we examine a scenario in which massive stars merge after they have both formed a hydrogen-exhausted core. We suggest that this could produce stars that explode as pair-instability supernovae (PISNe) with significantly more hydrogen, at a given metallicity, than in single-star models with the same pre-explosion oxygen-rich core mass. We investigate the subset of those stellar mergers that later produce pulsational PISNe, and estimate that the rate of such post-merger, hydrogen-rich pulsational PISNe could approach a few in a thousand of all core-collapse supernovae. The nature and predicted rate of such hydrogen-rich pulsational PISNe are reminiscent of the very unusual supernova iPTF14hls. For plausible assumptions, PISNe from similar mergers might dominate the rate of PISNe in the local Universe.
Late Afterglow Emission Statistics: A Clear Link between GW170817 and Bright Short Gamma-Ray Bursts

Published: May 2019

Abstract
GW170817, the first neutron star merger event detected by Advanced LIGO/Virgo detectors, was associated with the underluminous short-duration GRB 170817A. In this Letter we compare the forward shock afterglow emission of GW170817/GRB 170817A to other luminous short gamma-ray bursts (SGRBs) with both a known redshift and an afterglow emission lasting at least one day after the burst. In the rapid decay phase, the afterglow emission of the bright SGRBs and GW170817/GRB 170817A form a natural and continuous sequence, though separated by an observation time gap. If viewed on-axis, in the bursters’ frames the forward shock afterglow emission of GW170817/GRB 170817A would be among the brightest detected thus far. This provides strong evidence for the GW170817-like merger origin of bright SGRBs, and suggests that the detection of the forward shock afterglow emission of most neutron star merger events are more challenging than the case of GW170817, as usually the mergers will be more distant and the viewing angles are plausibly higher.
Effects of Radius and Gravity on the Inner Edge of the Habitable Zone

Published: May 2019

Abstract
A rigorous definition of the habitable zone and its dependence on planetary properties is part of the search for habitable exoplanets. In this work, we use the general circulation model ExoCAM to determine how the inner edge of the habitable zone of tidally locked planets orbiting M dwarf stars depends on planetary radius, surface gravity, and surface pressure. We find that the inner edge of the habitable zone for more massive planets occurs at higher stellar irradiation, as found in previous 1D simulations. We also determine the relative effects of varying planetary radius and surface gravity. Increasing the planetary radius leads to a lower planetary albedo and warmer climate, pushing the inner edge of the habitable zone to lower stellar irradiation. This results from a change in circulation regime that leads to the disruption of the thick, reflective cloud deck around the substellar point. Increasing gravity increases the outgoing longwave radiation, which moves the inner edge of the habitable zone to higher stellar irradiation. This is because the column mass of water vapor decreases with increasing gravity, leading to a reduction in the greenhouse effect. The effect of gravity on the outgoing longwave radiation is stronger than the effect of radius on the planetary albedo, so that increasing gravity and radius together causes the inner edge of the habitable zone to move to higher stellar irradiation. Our results show that the inner edge of the habitable zone for more massive terrestrial planets occurs at a larger stellar irradiation.
Dispersal history of the golden jackal (Canis aureus moreoticus Geoffroy, 1835) in Europe and possible causes of its recent population explosion
Authors: Spassov Nikolai , Acosta-Pankov Ilya 
Published: May 2019

Data on the historical distribution of the golden jackal in Europe and its primary habitats are scarce. There are many new data on the population explosion and the rapid spread of the in Europe. However, the main factors for this expansion, the core population and its routes of dispersal, remain controversial or insufficiently studied.
This study provides a profound analysis of the history of the jackal’s (Canisaureusmoreoticus Geoffroy, 1835) occurrence in Europe, the factors limiting or those triggering its expansion on the continent. The analysis shows that the timing of the species appearance in Europe still remains unclear. Historical data show that the species is a typical inhabitant of South-Eastern Europe, with some pulsations within its core area, as well as extensions to the north and west of it in favourable periods. Nowadays, the increase of the species range in Europe is the largest documented population explosion on the continent. We argue that this expansion originates from only three core populations, the Peri-Strandja area and the Dalmatian coast in the Balkans and the east parts of Western Transcaucasia in the Caucasus. This population explosion is largely due to a unique combination of factors of an anthropogenic nature.
Impact of hydromorphological pressures on the macrophytes bioindicators of the ecological water quality in Mediterranean rivers
Authors: Abdellah Maissour , Saad Benamar 
Published: May 2019

One of the important tools to evaluate the ecological quality of surface water is the Macrophytes indices based on the bioindication capacity of aquatic plants. In Mediterranean rivers (France, Spain, and Portugal), the development of some macrophytes indices like l’Indice Biologique Macrophytes Rivières (IBMR), the biological metric score (BMS), as well as the Fluvial Macrophyte Index (IMF) are founded on the determination of the indicator values of the floristic reference lists.The aim of this study was to test the impact of the eco-Mediterranean differences (from one country to another) on the indicator taxa by comparing the indicator values of the Euro‐ Mediterranean macrophyte indices. With this in mind, we explore the possibility of the introduction of the Euro‐Mediterranean macrophytes-based indices in Morocco (i.e. the hydrological basin of Sebou (HBS)) as a part of a preliminary attempt to develop the first Afro-Mediterranean macrophyte index.We confirm that the ecological amplitude and species optima vary between Mediterranean ecoregions, and indicator taxa differ between countries: There are medium to small correlations between Mediterranean indices: IBMR/BMS (p = 0.000, R2= 0.57), IMF/BMS (p = 0.000, R2= 0.34), and IBMR/IMF (p = 0.000, R2= 0.30). Five species exhibit major differences in indicator values:ZannichelliapalustrisandPotamogetonpectinatushave more eutrophic indicator values in France (IBMR) than in Spain (IMF).Potamogetonnodosus,AmblystegiumripariumandLycopuseuropaeushave broader ecological amplitudes in Portugal (BMS) than in France (IBMR) and in Spain (IMF), where it is restricted to eutrophic conditions. Furthermore, the three indicator systems include different indicator-taxon numbers.The comparison of the HBS elaborated list with the Euro‐Mediterranean indices revealed the low level of common taxa approximately 6.76% of all indicator species used in the French index (IBMR), 10.48% in the Portuguese index (IMF) and 12.38% in the Spanish index (BMS).These results show the inadequacy of the trophic indices approach with the HBS conditions and thus the need for the development of an index based on biotic indices approach.
