Authors: Mohammed A. A. 
Published: June 2020

The objective of this study to estimate the Radiation Use Efficiency under effect of three levels of nitrogen (N1 = 80 Kg N ha-1, N2 =120 Kg N ha-1, and N3=160 Kg N ha-1) for a set of maize hybrids include (Gloria, Market, Cruze and Draxma) in two different seasons in spring and fall of 2017 in Qlyasn-Sulaimani. The experiment was conducted using split plot design with three replicates . The results revealed higher intensity of PAR in autumn season than that of spring (15.672 and 10.555)MJm-2d-1 respectively that led to higher RUE in autumn revealing (4.311,3.546, and 4.702)g MJ-1 m-2 under the effect of (N1,N2, and N3) respectively, while the results of the autumn were higher (5.237, 4.681, and 6.019) g MJ-1 m-2 under the same levels of nitrogen fertilization, the highest application of nitrogen was more effective in autumn. The RGR and the rate of total dry matter accumulation were higher in autumn season displaying positive performance of studied maize hybrids to the higher intercepted of solar energy as well higher temperature.

Published: June 2020

Methylation Sensitive Amplification Polymorphism (MSAP) was used to characterize the alterations in DNA methylation in maize (Zea mays L.) inbred lines and their half-daillels affected by plant densities (213333 plant h-1 and 13333 plant h-1). The two restriction was enzymes ( HpaII and MspI) succeeded in diagnosing a total of 23 specific loci, most of (22 loci) were Methylation Sensitive Loci (MSL), while the only one NML (No Methylated Loci) was monomorphic. Thirteen out of 22 MSL loci polymorphic, recording a were polymorphism percentage of 59%. Results of FeSOD gene expression cleared the different response of maize inbreds and hybrids to high plant density stress. Generally, the expression of the targeted gene was increased in plants submitted to high plant density stress compared with low density. The inbred 3 and its single hybrid 1×3 achieved the highest level of gene expression under high planting density (5505.7 and 21098.6 copy, respectively), meanwhile, inbred 5 and it's single hybrid 4×5 gained the maximum level of FeSOD expression at the low plant density (8317.6 and 6862.1 copy, respectively). The response reached to its maximum limit in many of those genotypes, some other genotypes showed relatively steady performance along with higher stress, such as parent 1, that gave the lowest number of gene copies in both, high and low plant density (1375.8 and 1569.5 copy, respectively).

The efficiency of management is determining factor for the success or failure of agricultural projects generally and Livestock particularly achieving its objectives. Therefore, this research came to diagnose the most important variables that determine the efficiency of management using the probability regression models to measure the probability of management efficient of broilers production projects using random sample included (60) broilers projects represented 11.6% of Baghdad province (research community) in 2016. After estimating the relationship between the management efficiency (descriptive dependent variable) and the independent variables affecting it (age, educational level, production index (PI), experience). The results showed that the parameters of these variables were positive according the economic logic, except for the parameter of the experience variable, which was negative contrary to economic logic. The results showed that the independent variables were significant at 1% and 5% levels in logit and probit models, except the PI variable, which was insignificant in the Tobit model. By comparing the results of the three models and the tests performed, the probit model showed its preference. The age and educational level were most important independent variables affecting the efficiency of management, the suggested recommendations of the research indicated to increase the efficiency of the administration through training courses to train workers and teach them to follow the modern methods in poultry production and raise the scientific methods because of its impact in increasing productivity.

Authors: &et al. AL-Azawi 
Published: June 2020

There is great interest for NPs manufacturing by environmentally friendly and economic manner. The aqueous leaves extract of Thuja orientalis was used to synthesized silica nanoparticles (SiO2NPs) by using two green methods, the first one is the magnetic stirrer method and the second method by using the cold plasma. The XRD pattern for both samples annealed at Ta=600˚C for 1h, while they showed the characteristic of Bragg peaks for poly phases at (001), (010), (10-1), (1-10), (0-12) and (002) for SiO2 triclinic (anorthic). The average crystalline size was calculated by using Scherer’s formula, which was 11.1868 nm in magnetic stirrer method, while the cold plasma method showed amorphous structure. The morphology analysis using atomic force microscopy showed that the grain size was 33.94 and 18.37 nm for magnetic stirrer and cold plasma methods respectively. Fourier Transform Infrared Spectroscopy (FTIR) analysis indicates hydrophilic functional groups in the capping matrix, which can improve the stability of silica NPs. The biofilm inhibition of silica NPs were investigated for two genus of bacteria Staphylococcus aureus and Escherichia coli, the green silica NPs that synthesized by using cold plasma method showed the highest inhibition effect on S. aureus and E. coli respectively.

Nustatyta, jog sergantieji šia liga linkę sirgti 1 tipo cukriniu diabetu (CD), nes abi ligas sieja bendra genetinė kilmė. Pasaulyje celiakijos dažnis 1 tipo cukriniu diabetu sergančiųjų populiacijoje yra nuo 5 iki 16 kartų didesnis nei bendrojoje. Dažnai celiakija sergant 1 tipo CD yra asimptomė, tačiau celiakijos negydant yra bloga glikemijos kontrolė, didesnė širdies ir kraujagyslių sistemos ligų rizika, didėja cukrinio diabeto komplikacijų pasireiškimo rizika jaunesniame amžiuje. Šiuo metu nėra vieningos nuomonės dėl celiakijos diagnozavimo ir gydymo sergant 1 tipo CD. Pagrindinis celiakijos gydymo būdas yra ilgalaikė begliutenė dieta, todėl šis gydymas rekomenduojamas ir sergant abiem minėtomis ligomis, tačiau besilaikantys šios dietos sergantieji 1 tipo CD turi būti atidžiai prižiūrimi gydytojų endokrinologo ir dietologo.
Spatially Resolved Velocity Structures in Jets of DF Tau and UY Aur A

Published: June 2020

Abstract
Young stars accrete mass and angular momentum from their circumstellar disks. Some of them also drive outflows, which can be distinguished in optical forbidden emission lines. We analyze a sample of binary T Tauri stars observed with long-slit spectroscopy by the Hubble Space Telescope between 1998 and 2000, searching for spatially resolved outflows. We detect resolved [O i] emission in 2 cases out of 21. In DF Tau we resolve high- and medium-velocity outflows in a jet and counterjet out to 60 au. The outflows are accelerated within the inner 12 au and retain a constant speed thereafter. In UY Aur, we detect a blue- and a redshifted outflow from UY Aur A, as well as a blueshifted jet from UY Aur B. All of these features have been seen in [Fe ii] with data taken 10 years apart indicating that the underlying outflow pattern is stable on these timescales.
Network Jets as the Driver of Counter-streaming Flows in a Solar Filament/Filament Channel
Authors: Panesar Navdeep K. , Tiwari Sanjiv K. , Moore Ronald L. , Sterling Alphonse C. 
Published: June 2020

Abstract
Counter-streaming flows in a small (100″ long) solar filament/filament channel are directly observed in high-resolution Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) extreme-ultraviolet (EUV) images of a region of enhanced magnetic network. We combine images from SDO/AIA, SDO/Helioseismic and Magnetic Imager (HMI), and the Interface Region Imaging Spectrograph (IRIS) to investigate the driving mechanism of these flows. We find that: (i) counter-streaming flows are present along adjacent filament/filament channel threads for ∼2 hr, (ii) both ends of the filament/filament channel are rooted at the edges of magnetic network flux lanes along which there are impinging fine-scale opposite-polarity flux patches, (iii) recurrent small-scale jets (known as network jets) occur at the edges of the magnetic network flux lanes at the ends of the filament/filament channel, (iv) the recurrent network jet eruptions clearly drive the counter-streaming flows along threads of the filament/filament channel, (v) some of the network jets appear to stem from sites of flux cancelation, between network flux and merging opposite-polarity flux, and (vi) some show brightening at their bases, analogous to the base brightening in coronal jets. The average speed of the counter-streaming flows along the filament/filament channel threads is 70 km s−1. The average widths of the AIA filament/filament channel and the Hα filament are 4″ and 2.″5, respectively, consistent with the earlier findings that filaments in EUV images are wider than in Hα images. Thus, our observations show that the continually repeated counter-streaming flows come from network jets, and these driving network jet eruptions are possibly prepared and triggered by magnetic flux cancelation.
The State of the Heliosphere Revealed by Limb-halo Coronal Mass Ejections in Solar Cycles 23 and 24
Authors: Gopalswamy Nat , Akiyama Sachiko , Yashiro Seiji 
Published: June 2020

Abstract
We compare the properties of halo coronal mass ejections (CMEs) that originate close to the limb (within a central meridian distance range of 60°–∼90°) during solar cycles 23 and 24 to quantify the effect of the heliospheric state on CME properties. There are 44 and 38 limb halos in cycles 23 and 24, respectively. Normalized to the cycle-averaged total sunspot number, there are 42% more limb halos in cycle 24. Although the limb halos as a population are very fast (average speed ∼1464 km s−1), cycle-24 halos are slower by ∼26% than the cycle-23 halos. We introduce a new parameter, the heliocentric distance of the CME leading edge at the time a CME becomes a full halo; this height is significantly shorter in cycle 24 (by ∼20%) and has a lower cutoff at ∼6 R

s
. These results show that cycle-24 CMEs become halos sooner and at a lower speed than the cycle-23 ones. On the other hand, the flare sizes are very similar in the two cycles, ruling out the possibility of eruption characteristics contributing to the differing CME properties. In summary, this study reveals the effect of the reduced total pressure in the heliosphere that allows cycle-24 CMEs to expand more and become halos sooner than in cycle 23. Our findings have important implications for the space-weather consequences of CMEs in cycle 25 (predicted to be similar to cycle 24) and for understanding the disparity in halo counts reported by automatic and manual catalogs.
The effects of neutron irradiation on the physicomechanical properties of refractory metals
Authors: Zakharova Maria I. , Tarasikov Vladimir P. 
Published: June 2020

Studying the interaction of radiation defects with defects in the crystal lattice in the initial state makes it possible to distinguish the contribution of each type of defect to changes in the physicomechanical properties of materials exposed to irradiation. When comparing the changes in the properties of the metals with the body-centered cubic (BCC) lattice (Mo, W, V, Nb) and hexagonal close-packed (HCP) lattice (Re), we see common features and differences in their behavior under irradiation:
− both HCP and BCC crystals show an orientation dependence of their properties; at the same time, the metals with the BCC lattice are characterized by an increase in the size of the sample in all crystallographic directions, whereas, for the HCP crystals, the sample is narrowed along the &lt;0001&gt; direction, perpendicular to the plane with the closest packing of atoms, and expanded along other directions;
− for the BCC samples, the elastic moduli decrease; for the HCP samples, the shear modulus increases significantly as a result of irradiation;
− electrical resistance for the metals of Group 6 (Mo, W) and rhenium as a result of irradiation increases; for the metals of Group 5 (V, Nb), it decreases: this decrease in electrical resistance is associated with the release of interstitial impurity atoms to radiation defects;
− for the BCC crystals, relaxation processes occur both in the unirradiated and irradiated samples, whereas, in the HCP crystals, only irradiation and post-irradiation annealing cause the temperature dependence of internal friction (TDIF) and the appearance of a relaxation maximum due to a change in the point symmetry of the defect; and
− during isochronous annealings up to 0.7×Тm, behavior features associated with the crystal lattice structure are retained.

Construire des publics pour se saisir de l’actualité
Authors: Rohde Juliette 
Published: June 2020

Saisir est une association d’éducation populaire et d’éducation aux médias qui organise des « ateliers populaires de décryptage de l’actualité ». Le principe en est simple : une organisation – association, entreprise, café, collectivité locale – propose à son public de se réunir environ deux heures pour débriefer ensemble de l’actualité du moment. Derrière ce format se cache le triple pari de l’ oralité , de l’ altérité et de l’ unité de temps et d’espace . Au lieu d’écouter ou de voir les informations en état de solitude passive, Saisir invite à formuler avec autrui ce qui peut être une signification commune de ces informations.
