Degradation of ecosystems in the region of Agro Karya Prima Lestari Ltd causing this region un function well as wildlife habitat. This is indicated by the low level of wildlife encounters, both on observations during this study took place as well as from interviews with some of the people who live in the area. Based on the results of field observations during the course of the study, it is known there are 19 species of mammals, 47 species of birds and 5 species of reptiles. Based on the results of the analysis, it is known that this area contains 10 species of mammals, 16 species of birds and four species of reptiles that includes the category of rare / protected
Characteristics of farming systems in Albania
This report is based on information collected from a face-to-face survey of more than 1 000 farmers from three regions of Albania (namely Berat, Elbasan and Lezhë
To identify a representative sample of Albanian farming systems, a three-step sample design was used. A group of 11 variables dealing with the socio-economic characteristics of farms was selected to build up the farming system typology. Two typologies are used: one for the whole sample (three regions) and a second one for each region. The differences between the two typologies are considered to be a proxy indicator of different characteristics of farming systems in each region. The farm types identified are (1) poly-culture, mainly for the market; (2) leisure farms; (3) arable crops; (4) fruit trees; (5) self-sufficient; and (6) livestock. The farm typology is slightly different for the regions of Berat and Lezhë.
The farm types’ strategies are constructed according to the land, infrastructure facilities and the investment availability of farms. Non-agricultural incomes (remittances, income from the construction, trade, pensions, etc.) appear to provide an important economic support for the farm household.
Farming structures in rural areas are characterised by the use of more labour and lower inputs. The farm types that tend to specialise in one activity are not always those that make the best use of labour and land.
Farming does not provide enough income to repay the work put in at the official minimum wage level. Non-agricultural work is better paid. Albanian farms provide at least a minimal income that is enough to keep the household members above the threshold of extreme poverty.
The farm types that base their incomes on agricultural activities are poorer than those that base their income on non-agricultural activities. Income structures and the low incomes generated by work in agriculture suggests that rural migration towards urban areas and abroad is a phenomenon that will persist into the future.JRC.J.4-Agriculture and Life Sciences in the Econom
All-sky Search for High-Energy Neutrinos from Gravitational Wave Event GW170104 with the ANTARES Neutrino Telescope
Advanced LIGO detected a significant gravitational wave signal (GW170104)
originating from the coalescence of two black holes during the second
observation run on January 4, 2017. An all-sky high-energy
neutrino follow-up search has been made using data from the ANTARES neutrino
telescope, including both upgoing and downgoing events in two separate
analyses. No neutrino candidates were found within s around the GW
event time nor any time clustering of events over an extended time window of
months. The non-detection is used to constrain isotropic-equivalent
high-energy neutrino emission from GW170104 to less than
erg for a spectrum

Infinitesimal sulfur fusion yields quasi-metallic bulk silicon for stable and fast energy storage
A fast-charging battery that supplies maximum energy is a key element for vehicle electrification. High-capacity silicon anodes offer a viable alternative to carbonaceous materials, but they are vulnerable to fracture due to large volumetric changes during charge???discharge cycles. The low ionic and electronic transport across the silicon particles limits the charging rate of batteries. Here, as a three-in-one solution for the above issues, we show that small amounts of sulfur doping (<1 at%) render quasi-metallic silicon microparticles by substitutional doping and increase lithium ion conductivity through the flexible and robust self-supporting channels as demonstrated by microscopy observation and theoretical calculations. Such unusual doping characters are enabled by the simultaneous bottom-up assembly of dopants and silicon at the seed level in molten salts medium. This sulfur-doped silicon anode shows highly stable battery cycling at a fast-charging rate with a high energy density beyond those of a commercial standard anode
Attenuation of Vaccinia Tian Tan Strain by Removal of Viral TC7L-TK2L and TA35R Genes
Vaccinia Tian Tan (VTT) was attenuated by deletion of the TC7L-TK2L and TA35R genes to generate MVTT3. The mutant was generated by replacing the open reading frames by a gene encoding enhanced green fluorescent protein (EGFP) flanked by loxP sites. Viruses expressing EGFP were then screened for and purified by serial plaque formation. In a second step the marker EGFP gene was removed by transfecting cells with a plasmid encoding cre recombinase and selecting for viruses that had lost the EGFP phenotype. The MVTT3 mutant was shown to be avirulent and immunogenic. These results support the conclusion that TC7L-TK2L and TA35R deletion mutants can be used as safe viral vectors or as platform for vaccines
Searches for neutrinos in the direction of radio-bright blazars with the ANTARES telescope
Active galaxies, especially blazars, are among the most promising neutrino
source candidates. To date, ANTARES searches for these objects considered
GeV-TeV -ray bright blazars. Here, a statistically complete
radio-bright blazar sample is used as the target for searches of origins of
neutrinos collected by the ANTARES neutrino telescope over 13 years of
operation. The hypothesis of a neutrino-blazar directional correlation is
tested by pair counting and by a complementary likelihood-based approach. The
resulting post-trial -value is ( in the two-sided
convention), possibly indicating a correlation. Additionally, a time-dependent
analysis is performed to search for temporal clustering of neutrino candidates
as a mean of detecting neutrino flares in blazars. None of the investigated
sources alone reaches a significant flare detection level. However, the
presence of 18 sources with a pre-trial significance above indicates
a ( in the two-sided convention) detection of a
time-variable neutrino flux. An \textit{a posteriori} investigation reveals an
intriguing temporal coincidence of neutrino, radio, and -ray flares of
the J0242+1101 blazar at a ( in the two-sided convention)
level. Altogether, the results presented here suggest a possible connection of
neutrino candidates detected by the ANTARES telescope with radio-bright
blazars
