Abstract
This research was conducted to investigate the effect of Allicin and Ginger supplementation to the rations of Awassi lambs on some cellular and biochemical blood parameters with ruminal fermentation. A total number of 28 Awassi lambs were used in this experiment, those lambs were divided in to 4 equal groups. The 1st group was used as a control (without any supplement), the 2nd group was supplemented with 3 kg Allicin/ton of feed, the 3rd group was supplemented with Ginger 2 kg/ton of feed, meanwhile the 4th group was supplemented with the append of Allicin 1.5 kg/ton with 1.0 kg/ton of Ginger. The results illustrate a highly significant difference (p< 0.01) in WBCs, RBCs, BCV and Hb as well as blood glucose, cholesterol, urea, triglycerides and the total protein. Additionally, the rumen pH, ammonia nitrogen as well as Total volatile fatty acids were significantly affected due supplementation of Allicin with Ginger during the mid-experiment (45 days) except the triglycerides with total protein which were recorded surpassing during the end of the experiment (90 days). The rumen fermentation was surpassed in groups of lambs which were supplemented with Allicin with Ginger in comparison with the control group during the second aspiration (after 3 hours of morning feeding), the rumen pH was significantly elevated, meanwhile, the ammonia nitrogen and total volatile fatty acids were reduced with advanced age during morning feeding. It was concluded that supplementing of Allicin or Ginger had been affected some blood parameter as well as rumen fermentation due to the utilization of feed supplements which gave a superior animal performance.

To study the effect of spraying with four concentrations of Humiforte 0, 2, 4 and 6 L.ha−1on growth and yield of four Oats cultivars. The layout of the experiment was split plot design according to RCBD design with three replicates. The results showed the following: The characters of the yield and yield components of oats were studied in terms of performance and variability and calculated the values of genetic and environmental variability and the heterogeneity, phenotypic and inheritance. The highest percentage of genetic variations to the environment 7.2, 10.9 and 13, 7 for the flag leaf area and the number of grains by the raceme in both seasons. the highest percentage of heritability was found in flag leaf area reached 87.8%, 91.60 and the number of grains by the raceme which reached 92.72% and 87.36% in both seasons. The concentration of 6 L.ha−1was superior compared to the other concentrations in plant height, leaf area, number of branches per plant, leaf content of chlorophyll, yield components and grain yield 6.01 and 6.29 ton.ha−1in both seasons respectively. Genzaniya and Hamel cultivars gave the lowest number of days to reach the flowering stage, while Gensaniya cultivar gave the highest plant height, leaf area, chlorophyll leaf content, number of grains by raceme and grain yield 5.47 and 6.48 ton.ha−1in both seasons respectively. However, Shefaa was superior in the weight of 500 grains in both seasons. The interaction between the study factors was significant in most of the studied characters. The treatment of Gensaniya at the concentration of 6 L.ha−1gave the highest grain yield reached 6.86 and 7.22 ton.ha−1in both seasons respectively. We conclude from this results that most components of the crop are more influenced by genetics factors. Therefore, we recommend the adoption of the number of grains per raceme in the assessment of productive capacity of the oats grains.

Abstract
This study has been undertaken to investigate the mineralogical properties and morphological features of sand fraction in some soils of Baghdad / Iraq.The morphological features of sand fractions were studied by Polarized optical microscope. Results have shown that the grains of these minerals from samples of sands have different colors, those from the surface horizons have dark brownish spots, due to staining by organic matter, and have a yellowish– to yellowish brown spots due to accumulation of Iron oxides.Results of light minerals indicated that quartz is dominant due to effect of parent material of these soils. Two types of opaque minerals (black and brown) are found, whereas the brown opaque minerals were obvious in heavy minerals.Three groups of transparent heavy minerals are found, stable minerals (Pyroxen and Amphibole), metastable minerals (Epidote and Garnet), and Ultra stable minerals (Zircon and Tourmaline).

Published: October 2019

Abstract
An optimal configuration of the waveguide acousto-optic frequency shift modulators on the X-cut lithium niobate substrates was analyzed. The conditions for efficient excitation of surface acoustic waves (SAW) and their interaction with the guided light in integrated optical structures were found. The influence of acoustic waveguide presence and interdigital transducer (IDT) geometry and material on the SAW resonance excitation was investigated. An acoustic waveguide configuration was proposed for increasing the TE-TM optical mode conversion efficiency. A low power (about 15 dBm) high frequency modulation signal was required for full TE-TM mode conversion in the proposed modulator configuration.

Development and implementation of accelerated methods of data access
Authors: Ermakov N V , Molodyakov S A 
Published: October 2019

Abstract
In this paper we address the problem of organizing a permission-conscious access to files and their metadata. A large amount of data is required to be stored and analyzed in medicine, bioinformatics, astronomy, and banking. For effective data storage, it is necessary to apply different technologies depending on the data. We have developed a system that consists of the following components: a relational DBMS to store user permissions and file metadata; an off-the-shelf distributed search engine to store activity logs; a distributed cache with permissions; a file system; a special application that interacts with all the respective components. We describe the overall architecture of our approach and discuss each component in detail. To offload database server and to speed up the permission checking we have devised a simple data caching scheme that is performed on an application server. The idea was to manually rewrite queries that are used by our application to check permissions. As a result, queries that use several tables request only non-cached tables from the database. We conclude our paper with the experimental evaluation of our system and the proposed caching approach.

Authors: Popov N P , Pogarskaia T A 
Published: October 2019

Abstract
The problem of geodesic distance computation in the Aircraft industry is considered in the paper. While simulating the assembly process, in some computational problems the calculation of the shortest distances between different objects is required. The aim of the work is to compare several approaches to geodesic distance numerical computation on test geometry and some of the most common joints of aircraft. The first considered approach represents graph-based algorithms. In the paper, geodesic distances are calculated in the constructed graph using Dijkstra’s algorithm or its modification with binary heap. The second approach is the fast marching method, which is based on the solution of the Eikonal equation and provides efficient geodesic distance computation on triangulated surfaces.

Published: October 2019

Abstract
In this paper, simulation modelling of information transmission using spectrally efficient multi-frequency (SEFDM) signals with an amplifier and a limiter on transmission has been held. SEFDM signals have a high peak-to-average power ratio (PAPR). Therefore, we need to limit the value of PAPR to increase the efficiency of the amplifier stages of transceiver devices. An effective value for PAPR limiting has been found. For signal-to-noise ratio 7 dB, level of bit error rate reaches minimum value when the PAPR limit value is within 4.5-5.5 dB. Besides that, a comparison of the effectiveness of detection algorithms with and without feedback has been made. The results showed that detection algorithm with feedback increases the effectiveness of the multi-frequency signals application under conditions of amplitude limitation.

Authors: Temkina V S , Mayzel A V 
Published: October 2019

Abstract
Optical fiber sensors are of particular interest for applications in the high-voltage environments of the electric power industry due to their characteristic properties including dielectric nature, immunity to electro-magnetic interference, and small size and weight. We have studied current sensor that employs the Faraday effect in the spun fiber and signal processing based on the additional harmonic modulation of the self-consistent polarization interferometer. We replaced the traditional PZT transducer with the LiNbO3 waveguide electro-optical modulator that allowed to increase significantly the modulation frequency and to reduce the length of the fiber delay line. Original error compensation methods allowed us to achieve the accuracy of ±0.2% in amplitude in the temperature range of about 50 °C.
