Dampak perubahan iklim pada produksi apel di Batu Malang Impacts of climate change on production of apple in Batu Malang
Authors: Ruminta Ruminta 
Published: May 2018

Perubahan iklim telah menjadi isu penting yang mengakibatkan kenaikan suhu global, perubahan pola curah hujan, kenaikan muka air laut, dan peningkatan frekwensi dan intensitas cuaca ekstrim. Perubahan iklim mempunyai pengaruh signifikan pada bidang pertanian, karena pertanian mempunyai ketergantungan yang kuat terhadap unsur iklim. Terkait dengan hal itu telah dilakukan penelitian dampak perubahan iklim terhadap produksi tanaman apel di wilayah Batu Malang Jawa Timur. Penelitian bertujuan untuk mengetahui dampak perubahan unsur iklim yaitu temperatur dan curah hujan terhadap produksi apel dan mengidentifikasi usaha adaptasi yang harus dilakukan oleh para petani. Hasil penelitian menunjukkan bahwa wilayah Batu Malang telah mengalami perubahan iklim. Dampak perubahan iklim tersebut terhadap penurunan produksi apel tidak signifikan. Penurunan produksi apel di Batu Malang lebih disebabkan oleh faktor non iklim seperti: tanaman apel sudah berumur tua; budidaya apel kurang intensif; konversi lahan tanaman apel; dan harga apel yang semakin turun. Adaptasi terpenting yang harus dilakukan oleh petani adalah rehabilitasi tanaman apel; menanam bibit apel yang unggul yang mampu beradaptasi dengan perubahan iklim; dan mengintensifkan teknik budidaya apel.

Published: May 2018

Produksi jagung di Indonesia belum mampu menutupi tingginya permintaan jagung nasional. Padi hitam pun secara umum mengalami kondisi yang sama. Upaya peningkatan produksi jagung dapat ditingkatkan melalui penggunaan jagung hibrida. Namun, penggunaan varietas hibrida akan mendatangkan permasalahan lingkungan karena over aplikasi pupuk sintetis. Modifikasi lingkungan secara aktif pada budidaya hibrida jagung dan padi hitam dapat dilakukan dengan cara tumpangsari. Hal ini merupakan salah satu solusi yang ramah lingkungan karena memperkaya bahan organik dan anorganik melalui pemilihan tanaman kedua secara selektif, mencegah gagal panen, diversifikasi pangan dan asupan nutrisi yang berbeda. Tujuan dari penelitian ini adalah mendapatkan varietas jagung hibrida unpad yang memiliki penampilan morfologi dan agronomi terbaik dalam tumpangsari dengan padi hitam di dataran tinggi. Percobaan lapangan menggunakan rancangan acak kelompok dengan 18 perlakuan jagung hibrida unpad dan 1 varietas komersil sebagai cek. Untuk mendapatkan Jagung hibrida terpilih analisis dilanjutkan dengan uji Least Significant Increase (LSI). Hasil penelitian memperlihatkan bahwa dalam kondisi tumpangsari dengan padi hitam, karakter panjang daundengan hibrida terpilih JH6, JH17, JH12, dan karakter bobot biji pipilan kering, dengan hibrida terpilih JH17, JH12, JH8, JH1 dan JH14, memberikan hasil tertinggi dibandingkan cek. Panjang daun dan bobot biji pipilan kering merupakan karakter penting terkait dengan hasil yang tinggi pada jagung hibrida. Namun, memberikan hasil yang sama pada tinggi tongkol dan kandungan klorofil. Untuk mendapatkan jagung hibrida unpad yang lebih stabil dan adaptif perlu dilakukan pengujian lebih lanjut pada musim dan ketinggian tempat yang berbeda.Kata kunci : Morfologi-Agronomi, hibrida, jagung, padi hitam, tumpangsari

Published: May 2018

Abstract Using inductively-coupled plasma mass spectrometry (ICP-MS), we measured the concentrations of thallium and uranium in local water resources from three villages (Ćelije, Draž, and Potnjani) in eastern Croatia, with the aim to determine if they were associated with the levels of these same elements in the serum, urine, and hair collected from the residents of this area. The exposure of the local population to thallium and uranium through drinking water was generally low. ICP-MS was capable of measuring the levels of both of the elements in almost all of the analysed samples. Although there were differences in the concentrations of both elements in water samples and biological specimens taken from the residents, they did not reach the maximum contaminant level in any of the four sample types studied. Although hair was previously reported as an excellent indicator of occupational and environmental exposure to various elements, our study did not confirm it as a reliable biological material for tracing thallium and uranium levels, mainly due to the very low concentrations of these elements, often well below the detection limit. However, our results have shown that the concentration of thallium and uranium in drinking water can be effectively traced in urine samples.
The Blood is Rich in Different Types of Mesoderm Derived Stem and Progenitor Cells
Authors: Kovačević Filipović Milica 
Published: May 2018

Abstract
The blood and bone marrow have been thoroughly investiagated for more than a century, but we are still gaining surprising new informations. Blood transports different mature cells such as erythrocytes, platelets and granulocytes, but curiously, the blood is also transporting a number of non-differentiated cells of various mesodermal lineages: hematopoietic and mesenchymal stem and progenitor cells, endothelial progenitor cells and very small embryonal like cells are some of the most impressive examples. In adults the bone marrow is the source of practiclly all cells that could be found in the blood. Stem and progenitor cells egress from the bone marrow and home to the bone marrow or various tissues in a highly regulated manner. The fact that the hematopoetic stem and progenitor cells traffic through the blood and repopulate the bone marrow niche is largely explored in stem cell therapy in human medicine. In this review we will briefly describe the main characteristics of stem and progenitor cells, the mechanisms of their mobilization from the bone marrow and homing to target tissues. Also, the history and importance of the fact that different stem, progenitor and precursor cells could be isolated from the blood circulation will be discussed in the light of informations concerning their use in human and veterinary medicine.

Published: May 2018

Abstract
The purpose of this study was to assess the genetic diversity of Serbian huchen and provide guidelines for conservation and management. Fourteen huchen individuals were collected from six localities. For all individuals the mitochondrial DNA control region and the NADH1 gene were sequenced, and two microsatellite loci were genotyped. Sequencing of two mtDNA loci showed the presence of the same haplotypes (Hh_CR_1 and Hh_ND1_1) in all investigated specimens and the complete absence of genetic variability at inter- and intra-populational level. However, analyzed individuals from Serbia have the largest number of control region repeats (average 8.7) compared to all other huchen populations from the Danube basin. Microsatellite data show that the most of Serbian huchens were placed in the “eastern” cluster except one individual from the Drina River which clustered with “western” samples, most likely a consequence of stocking. In spite of only two loci used, four unique alleles found in the studied Serbian and Drina basin population indicate that the Danube basin may possess more region specific alleles than previously thought, which could be of great importance for efficient species management in the future.

Published: May 2018

Abstract
The asymptotic stability of positive fractional switched continuous-time linear systems for any switching is addressed. Simple sufficient conditions for the asymptotic stability of the positive fractional systems are established. It is shown that the positive fractional switched systems are asymptotically stable for any switchings if the sum of entries of every column of the matrices of all subsystems is negative.

Published: May 2018

Abstract
The paper presents numerical analyses aimed at preliminary assessment of the protective panel effectiveness, which task is to protect the elements of building structures against explosion. For the criterion of assessing the effectiveness of the panel the load capacity of the column made of steel I-beam was chosen. Ultimate force was determined by using advanced computational procedure, which consisted of four stages: preload, blast simulation, dynamic response and static analysis of deformed structure. Blast load was simulated using Lagrangian- Eulerian domain coupling. Results indicated that the application of the protective panel significantly reduces the plastic deformation of the structure.

Published: May 2018

Abstract
High strain rate experimental tests are essential in a development process of materials under strongly dynamic conditions. For such a dynamic loading the Split Hopkinson Pressure Bar (SHPB) has been widely used to investigate dynamic behaviour of various materials. It was found that for different materials various shapes of a generated wave are desired. This paper presents a parametric study of Split Hopkinson Pressure Bar in order to find striker’s design variables, which influence the pulse peak shape in the incident bar. With experimental data given it was possible to verify the developed numerical model, which was used for presented investigations. Dynamic numerical simulations were performed using explicit LS-Dyna code with a quasi-optimization process carried out using LS-Opt software in order to find striker’s design variables, which influence the pulse peak shape.

Published: May 2018

Abstract
The aim of the study was to evaluate the status of bovine viral diarrhoea virus (BVDV) infection in selected dairy herds in Poland with the use of commercial enzyme linked immonosorbent assay for the detection of specific antibodies (BVDV-Ab ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) for the detection of viral RNA, using bulk tank milk (BTM) samples. Two hundred and thirty-one samples of BTM were collected from 99 dairy herds in Poland. The herds were divided into four different classes according to the Swedish system of classification. The results showed that 70.7% of herds were BVDV antibodypositive. High levels of antibodies in 52.85 % (37 herds in class 3) of all antibody positive herds indicated acute BVDV infection. Thirty five samples with the highest antibody levels were tested by RT-PCR and five of them were positive for viral RNA. Dairy herds in Poland have high levels of antibodies against BVDV in BTM. Since no vaccination was implemented in the herds tested, high seroprevalence of BVDV antibodies in cattle indicates the widespread of BVDV infection in Polish cattle.

Published: May 2018

Abstract
For the measurement of tulathromycin distribution in swine plasma an accurate and reliable analytical method was developed. The extraction was performed with oxalic acid buffer (pH=4.0). Plasma samples were cleaned up by solid phase extraction procedure using polymeric cartriges. Chromatographic separation was achieved on a C 18 analytical column using mobile phase consisting of acetonitrile, 0.1% formic acid in gradient mode. Detection was carried out by liquid chromatography tandem mass spectrometry. Azithromycin was used as internal standard. The method has been successfully validated. The recovery from spiked samples ranged from 94% to 110%. The limit of detection was 2 ng/mL and the limit of quantification was 5 ng/mL. The method was developed to investigate the pharmacokinetics of tulathromycin in swine plasma. Applicability of the method was tested with plasma from swine administered with a single dose of tulathromycin.

Published: May 2018

Abstract
The aim of the study was to evaluate the immune effects of genetically modified (GM), insect resistant corn (MON810) expressing toxin protein of Bacillus thuringiensis, and glyphosate-tolerant soybean meal (Roundup Ready MON-40-30-2), which are used as the feed mixture components in domestic animals. The study was conducted on 60 pigs (36 fatteners and 24 sows), 20 calves, 40 broilers, and 40 laying hens. Each species was divided into four basic nutritional groups: group I (control) - conventional feed, group II - feed consisted of GM soybean meal and non-modified corn, group III - non-modified soybean meal and GM corn, group IV - GM soybean meal and GM corn. Moreover, in the experiment on fatteners two additional groups were formed: group V - animals fed both conventional soybean meal and bruised grain, and group VI - GM soybean meal and conventional bruised grain. The results of study did not reveal any significant effect of feed mixtures containing GM components on the immune response in all animals regardless of their species and technological producing groups.
Gravimetric recovery of the Moho geometry based on a generalized compensation model
Authors: Tenzer Robert 
Published: May 2018

Abstract
Gravity data used for a recovery of the Moho depths should (optimally) comprise only the gravitational signal of the Moho geometry. This theoretical assumption is typically not required in classical isostatic models, which are applied in gravimetric inverse methods for a recovery of the Moho interface. To overcome this theoretical deficiency, we formulate the gravimetric inverse problem for the consolidated crust-stripped gravity disturbances, which have (theoretically) a maximum correlation with the Moho geometry, while the gravitational contributions of anomalous density structures within the lithosphere and sub-lithosphere mantle (including the core-mantle boundary) should be subtracted from these gravity data. In the absence of a reliable 3-D Earth’s density model, our definitions are limited to the crustal and upper mantle density structures. The gravimetric forward modeling technique is applied to compute these gravity data using available models of major known anomalous crustal and upper mantle density structures. The gravimetric inverse problem is defined by means of the (non-linear) Fredholm integral equation of the first kind. After linearization of the integral equation, the solution to the gravimetric inverse problem is given in a frequency domain. The inverse problem is formulated for a generalized crustal compensation model. It implies that the compensation equilibrium is (theoretically) attained by both, the variable depth and density of compensation. A theoretical definition of this generalized crustal compensation model and a formulation of the gravimetric inverse problem for finding the Moho depths are given in this study.
