Production and quality of semen in boars in insemination centre.

KAMANOVÁ VENDULA, HADAŠ ZDENĚK, NEVRKLA PAVEL. 2017. Production and Quality of Semen in Boars in Insemination Centre. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 65(4): 1189–1193. The aim of this study was to analyze production and quality of semen in boars in an insemination centre. Experimental material consisted of 8,052 semen samples collected from 146 boars. During the period of 5 years, an analysis of semen parameters was conducted. The obtained data were divided according to age of boars at the time of semen collection. Results showed that boars between 8 months and 3 years of age reached higher levels of semen volume, percentage of abnormal spermatozoa and number of spermatozoa. Older boars had lower sperm concentration levels. The largest total number of spermatozoa and corrected number of spermatozoa were observed in boars between 13 and 36 months of age. Later, the production of spermatozoa decreased. Based on the results of the presented study, the age category of 13 – 36 months can be recommended to dominate in the herd of boars in the insemination centre.
A New Scheme on Synchronization of Commensurate Fractional-Order Chaotic Systems Based on Lyapunov Equation

This paper proposes a new fractional-order approach for synchronization of a class of fractional-order chaotic systems in the presence of model uncertainties and external disturbances. A simple but practical method to synchronize many familiar fractional-order chaotic systems has been put forward. A new theorem is proposed for a class of cascade fractional-order systems and it is applied in chaos synchronization. Combined with the fact that the states of the fractional chaotic systems are bounded, many coupled items can be taken as zero items. Then, the whole system can be simplified greatly and a simpler controller can be derived. Finally, the validity of the presented scheme is illustrated by numerical simulations of the fractional-order unified system.
Virtual Bargaining as a Formal Account of Tacit Agreements

We provide a theoretical framework for understanding tacit agreements — agreements that are spontaneously understood even if they are not explicitly stated. To examine tacit agreements, we develop a general formal account of “virtual bargaining” — a mode of reasoning that joins elements of individualistic and collaborative reasoning — and apply it to five games representing broad classes of (one-shot and dynamic) interactions. The virtual bargaining account offers a unified framework to explain how people identify tacit agreements that either choose a specific Nash equilibrium (among multiple equilibria) or pick out options that are (experimentally well-known) deviations from the Nash equilibrium.
Effects of Dietary Nutrient Composition on Compensatory Growth of Grower Olive Flounder Paralichthys olivaceus under Different Feeding Regimes at Suboptimal Temperature

The effects of dietary nutrient composition on compensatory growth of grower olive flounder (Paralichthys olivaceus) under different feeding regimes at suboptimal temperature were determined. Four hundred five fish weighing 271.2 g were distributed into 27 300 L flow-through tanks (15 fish per tank). Nine treatments were prepared in triplicate: fish were hand-fed with control (C) diet for 12 weeks (12WF-C); four groups of fish were starved for 1 week and then fed C, high-protein (HP), high-lipid (HL), or combined high-protein and high-lipid (HPL) diets for 11 weeks; these groups are referred to as 11WF-C, 11WF-HP, 11WF-HL, and 11WF-HPL, respectively. Four other groups of fish were starved for 2 weeks and then fed C, HP, HL, and HPL diets for 10 weeks; these groups are referred to as 10WF-C, 10WF-HP, 10WF-HL, and 10WF-HPL, respectively. Weight gain and specific growth rate of fish from 12WF-C group were greater than those of fish from 11WF-C, 11WF-HP, 11WF-HL, 10WF-C, 10WFHP, and 10WF-HL groups, but not different from those of fish from 11WF-HPL and 10WF-HPL groups. Feed-efficiency ratio of fish from 12WF-C, 11WF-HP, 11WF-HPL, 10WF-HL, and 10WF-HPL groups was higher than that of fish in 11WF-C, 11WF-HL, 10WF-C, and 10WF-HP groups. The results of this study demonstrated that grower olive flounder subjected to 1- or 2-week feed deprivation were able to achieve full compensatory growth at suboptimal temperature only when fed HPL diet.
SACCHARIDE AND FRUCTOOLIGOSACCHARIDE ACCUMULATION ACROSS LEAF-BASES DURING GROWTH AND BULB DEVELOPMENT OF ONION (Allium cepa L.)

The accumulation of saccharides and fructooligosaccharides (FOS) in the individual leaf-bases of onion ( Allium cepa L.) was investigated during growth and bulb development. Saccharides and FOS were analysed by means of high performance anion exchange chromatography-pulsed amperometric detection (HPAEC-PAD). The glucose content was the highest, while the content of saccharides (glucose, fructose and sucrose) increased during June, July and August and decreased slightly during September. The trisaccharides all accumulated to a similar extent, although the neokestose [ 3b , 6 G - β -D fructofuranosylsucrose] content was higher than that of 1-kestose [ 3a , 1 F - β -D-fructofuranosylsucrose]. Tetra-, penta- and high-DP (degree of polymerization) FOS also showed a similar pattern, though the contents of 4b [6 G (1- β -D-fructofuranosyl) 2 sucrose] and 5b [6 G (1- β -D-fructofuranosyl) 3 sucrose] were higher compared with that of other tetra-[ 4a , 1 F (1- β -D-fructofuranosyl) 2 sucrose and 4c , 1 F , 6 G -di.
Why are immigrants and ethnic minorities more affected by working poverty? Theoretical framework and empirical evidence across welfare regimes

While the research that focuses on working poverty and low-wage employment usually explains the situation of immigrants and 'ethnic' minorities in terms of human capital, linguistic skills, social origin, and the like ('class-only' explanations), the literature that starts from the specific situation of minorities, especially the one that deals with immigration laws and/or labour market discrimination, tends to ignore what their situation has in common with that of disadvantaged 'native whites' in post-industrial economies. This paper attempts to build a theoretical bridge between these two strands of literature, and provides, in a first step, evidence as to the incidence of working poverty among immigrants (and 'ethnic' minorities when the information is available) across welfare regimes. In a second step, the impact of the citizenship status, the country of birth (and of 'race' in the US) is assessed, when the main working poverty factors and the main forms of labour market discrimination are controlled for. Interestingly, these variables have a significant impact in these models; hence, further factors must be at play, and some hypotheses are discussed, especially the role of 'ethnic economies'.

The long-term optical behaviour of helium-accreting AM CVn binaries

We present the results of a two and a half year optical photometric monitoring programme covering 16 AM CVn binaries using the Liverpool Telescope on La Palma. We detected outbursts in seven systems, one of which (SDSS J0129) was seen in outburst for the first time. Our study coupled with existing data shows that 1/3 of these helium-rich accreting compact binaries show outbursts. The orbital period of the outbursting systems lies in the range 24–44 min and is remarkably consistent with disc-instability predictions. The characteristics of the outbursts seem to be broadly correlated with their orbital period (and hence mass transfer rate). Systems which have short periods (30 min) tend to exhibit outbursts lasting 1–2 weeks and often show a distinct ‘dip’ in flux shortly after the onset of the burst. We explore the nature of these dips which are also seen in the near-ultraviolet. The longer period bursters show higher amplitude events (5 mag) that can last several months. We have made simulations to estimate how many outbursts we are likely to have missed.
Hybrid 3D Pose Recognition by Using Invariant Features Derived from Satellites

3D pose recognition is important as the intelligent function of autonomous robot. The pose recognition is achieved by two stages called an initial registration and a detailed registration. In the initial registration, a corresponding between the model and the scene is made roughly. On the other hand, in the detailed registration a highly accurate corresponding is made. In this paper two new invariant features called HSI_S (Horizontal Spin Image of Surface) and HSI_E (Horizontal Spin Image of Edge) are proposed, and parallel use of them is shown experimentally to improve generality of pose recognition. In addition to that, two different ICP algorithms called F-ICP and I-ICP are also proposed and parallel execution of these two ICP’s is shown experimentally to improve robustness to clutter and occlusion. The reason of that is that since focus regions of F-ICP and I-ICP are mutually complementary, the parallel execution of them (hybrid method) leads to the accuracy improvement. In this paper, several non-hybrid methods are compared to the hybrid method through pose recognition (registration) experiment of objects like auto parts and bird models. As a result, the proposed hybrid method with HSI_S and HIS_E has been shown to be better than single method (non-hybrid method) in its performance. That is, the proposed hybrids method is dominant in both generality and robustness.
Sedimentation in a dilute dispersion of spheres

The dispersion considered consists of a large number of identical small rigid spheres with random positions which are falling through Newtonian fluid under gravity. The volume fraction of the spheres (c) is small compared with unity. The dispersion is statistically homogeneous, and the axes of reference are chosen so that the mean volume flux across any stationary surface is zero. The problem is to determine the mean value of the velocity of a sphere (U). In §3 there is described a systematic and rigorous procedure which overcomes the familiar difficulty presented by the occurrence of divergent integrals, essentially by the choice of a quantity V whose mean value can be found exactly and which has the same long-range dependence on the position of a second sphere as U so that the mean of U – V can be expressed in terms of an absolutely convergent integral. The result is that, correct to order c, the mean value of U is U0(1 – 6.55 c), where U0, is the velocity of a single sphere in unbounded fluid. The only assumption made in the calculation is that the centres of spheres in the dispersion take with equal probability all positions such that no two spheres overlap; arguments are given in support of this assumption, which is expected to be valid only when the spheres are identical. Calculations which assume a simple regular arrangement of the spheres or which adopt a cell model of the hydrodynamic interactions give the quite different result that the change in the mean speed of fall is proportional to $c^{\frac{1}{3}}$, for reasons which are made clear. The general procedure described here is expected to be applicable to other problems concerned with the effect of particle interactions on the average properties of dispersions with small volume fraction of the particles.
PROPENSITY TO WORK ABROAD AMONGST GENERATION Y WORKING ADULTSS IN MALAYSIA

The main objective of this article is to examine the antecedents of influencing propensity to leave the country amongst generation Y working adults in Malaysia. Based on the present research literature review, a proposed conceptual framework has been developed. The study formulated a number of hypotheses concerning the generation Y working adults leaving Malaysia to work overseas. A crosssectional study and quantitative study were employed. The target population for this research was generation Y working adults in Malaysian. The sampling technique of convenient sampling was adopted. Online questionnaire method was used as a tool to conduct and collect samples. The initial stages of data analyses, various assumptions were well conducted. Multiple linear regression has been employed to test the proposed hypotheses. The study confirmed that a number of factors are significant related and contributed to propensity to leave the country amongst generation Y working adults in Malaysia. The study concluded with several useful recommendations and also highlighted potential improvement areas for future research.
Cyber Operation Planning and Operational Design

Improving ICT infrastructure, dramatic increase in internet usage and increasing dependence on networks have carried with cyber risks and threats. Complex, shape shifting and emerging risks and threats have systematically paved the way for cyberspace to emerge as a new domain after land, air, maritime and space. It is obvious enough that cyber threats probably continue to take part in global cyber theatre for years. However, it is sometimes hard to pinpoint at first a specific axis of cyber threats; they are generally varied merely from a simple computer code to systematic cyber strikes like targeted cyber attacks, cyber terrorism and industrial espionage activities. Due to the exponential use of cyberspace and the complex nature of cyber attacks, along with the multivariable cost they cause, it becomes a requirement for operation planners to handle cyber operations and the problems in this sphere in an operational design process. In this study, we tried to handle cyber operations in operational design process in order to comprehend, visualize and enlighten complex cyber incidents holistically and present preventive and systematic approaches by proposing a cyber operational design model. By presenting such model, we aim to help operation planners understand the complexity of cyber operations, show the advantage of using factor and center of gravity analysis (COG) that is generally handled in military decision making process (MDMP) and finally help the technical personnel to have an understanding of operational planning. With the cyber operational design presented as a sample in this study, we plan to provide the commanders with a comprehensive approach in cyber operations.
Evaluating spatially directing cues on a wearable user interface in a field setup

Die vorliegende Studie untersucht, wie raumliche Aufmerksamkeit und Handlungsfahigkeit in einer anspruchsvollen und anwendungsnahen Aufgabe durch kreuz- und multimodale Stimuli gesteuert werden kann. Tragbare Mensch-Maschinen-Schnittstellen (wearable user interfaces) werden vermutlich vorwiegend im Freien benutzt, wo sich Umstande und Umgebung standig andern konnen. Evaluationen sollten unter entsprechenden Umstanden erfolgen, weil Daten, die im Labor erhoben werden, weniger okologische Aussagekraft haben konnen. Fur die vorliegende Studie wurde daher ein angewandter Feldversuch unternommen. Auf einem Militarschiesplatz wurde eine Schiesubung durchgefuhrt, die eine zeitkritische Krisenmanagementaufgabe simuliert. Die Resultate sind aber auch auserhalb des militarischen Kontext nutzbar. Die Probanden wurden gebeten nach bestimmten Stimuli, auf eines von drei Zielen zu schiesen. Die Stimuli gaben die Richtung des Zieles vor und waren entweder visuell, auditiv, taktil oder multimodale Kombinationen dieser Stimuli. Alle diese Variationen wurden mit und ohne korpelichen Belastungsubungen durchgefuhrt, um die tatsachlichen Umstande eines Gefechts zu simulieren. Die verschiedenen Reiz-variationen wurden hinsichtlich Performanz (Reaktionszeit, Schussgenauigkeit, deren Abstimmung) und subjektiver Evaluierung (Fragebogen, Leitfaden-Interview) untersucht. Die Belastung durch die korperliche Ubung wurde mittels EKG und NASA-TLX kontrolliert und evaluiert. Aufgrund der gleichwertigen Resultate kann man die verschiedenen Modalitat-Variationen nicht in Rangfolge setzen weder hinsichtlich Performanz, noch hinsichtlich subjektiver Evaluierung. Die unterschiedlichen Modalitat-Variationen ergaben keine signifikante statistische Evidenz hinsichtlich der Performanz. Es konnte lediglich festgestellt werden, dass die Performanz nach der Belastungsubung tendenziell abnahm. Die Probanden hatten individuelle Praferenzen unter den Modalitaten. Fur jede Modalitat wurden Starken und Schwachen erlebt. Die Ergebnisse legen nahe, dass sich das Design einer kreuz- und multimodalen Aufmerksamkeitssteuerung mit einer tragbaren Mensch-Maschine-Schnittstelle sich auf die Nachweisbarkeit und Verlasslichkeit der Stimuli konzentrieren sollte. Man sollte die Aufgabenanforderungen und die Umstande sorgfaltig berucksichtigen, anstatt zu bestimmen versuchen welche Modalitat in der Schiessaufgabe die Reaktionszeit am meisten beschleunigt oder die Genauigkeit bei derselben verbessert. Die Nutzer-Evaluation in einem angewandten Feldversuch ist essenziell, und die Performanzmessungen konnen benutzt werden, um auf mogliche Probleme hinzuweisen, wie z.B. welche Anreize nicht bemerkt wurden.
In-situ measurements and temporal evolution of the thermal conductivity profile of an alpine snowpack

We report on a 3-months long time series of in-situ measurements of the thermal conductivity (kT) of snow at 6 fixed heights in an alpine snowpack in the Mont-Blanc mountain range, France, at an altitude of 2400 m. Automatic measurements were carried out every two days using the heated-needle probe technique. Results show consistent patterns of thermal conductivity increase throughout the measurements campaign. The temporal rate of change of kT varies up to 0.01 W m -1 K -1 d -1 , with maximum values just after snowfall. A cursory comparison of the measured kT values with the prediction of the snowpack model CROCUS shows that at first order the model performs rather satisfactorily. However, a quantitative understanding of the variations of kT over time would require an in-depth assessment of physical processes occurring during snow metamorphism.
No-tillage lessens soil CO 2 emissions the most under arid and sandy soil conditions: results from a meta-analysis

Abstract. The management of agroecosystems plays a crucial role in the global carbon cycle with soil tillage leading to known organic carbon redistributions within soils and changes in soil CO2 emissions. Yet, discrepancies exist on the impact of tillage on soil CO2 emissions and on the main soil and environmental controls. A meta-analysis was conducted using 46 peer-reviewed publications totaling 174 paired observations comparing CO2 emissions over entire seasons or years from tilled and untilled soils across different climates, crop types and soil conditions with the objective of quantifying tillage impact on CO2 emissions and assessing the main controls. On average, tilled soils emitted 21 % more CO2 than untilled soils, which corresponded to a significant difference at P 3 %). Finally, nitrogen fertilization and crop residue management had little effect on the CO2 responses of soils to no-tillage. These results suggest no-tillage is an effective mitigation measure of carbon dioxide losses from dry land soils. They emphasize the importance of including information on soil factors such as texture, aggregate stability and organic carbon content in global models of the carbon cycle.
SORPTION OF NON-FERROUS METAL CATIONS ON SPHEROGRANULATED AMOPTHOUS TITANIUM HYDROXIDE

The sorption properties of amorphous titanium hydroxide ion-exchanger (ATH) toward non-ferrous metal cations are investigated. The sol-gel synthesis of ATH is based on the method of limited hydrolysis of ammonium titanyl sulfate (NH4)2TiO(SO4)2·H2O (ATS) without the usage of organometalic compounds. The presence of ammonium ion in sol prevents the polymerization of gels, which has a positive impact on porosity of the obtained compounds and, consequently, on ionexchanging characteristics. The sorption isotherms for five divalent metal ions including Pb, Cd, Cu, Zn, and Ni are built. The isotherms are best described with the Freundlich model in the case of sorption of cadmium and lead cations, and with the Langmuir and Freundlich models in the case of sorption of zinc, copper and nickel cations. The sorption kinetics of these metal ions on the ATH is limited by internal diffusion. The selectivity order of the metal ions on TiP1 is determined as follows: Pb > Co > Cu > Ni > Cd > Zn. Additional sorption studies are carried on industrial water containing a mixture of divalent and hardness cations. The quality of water after the sorption on the ATH sorbent reaches the EU recommendations for drinking waters for most of the metal ions concentrations. In the case of wastewater treatment in tannery industry, the sorption of chrome cations on the ATH exceeds 99% for all types of wastewater and the remaining concentration of chrome ions (III, VI) in the solution is lower than maximum concentration limit.
Residential Edges as Ecological Traps: Postfledging Survival of a Ground-Nesting Passerine in a Forested Urban Park

ABSTRACT. Substantial offspring mortality can occur during the postfledging period of birds, but few postfledging survival studies have been conducted within the context of habitat suitability. We conducted a 2-year radiotelemetry study of Spotted Towhee (Pipilo maculatus) reproductive success and fledgling survival in a 24-ha forested park in a residential area of Lake Oswego, Oregon. In corroboration of previous research on this species, we found (1) that Spotted Towhees nested closer to the edge between the park and residential neighborhoods than expected by chance, and (2) that pairs nesting near edges produced the largest and most offspring. However, fates were reversed during the postfledging period. Thirty-six of 52 fledglings survived the 27-day tracking period, and although fledglings were more likely to be found near edges than in the interior, fledglings near edges had a far higher probability of dying. All deaths were from predation, and at least 11 of 16 predation events were attributable to Domestic Cats (Felis catus) and Western Screech-Owls (Megascops kennicottii). A stochastic model that incorporated probability of nest success, nestling production from successful nests, and fledgling survival showed that the number of independent offspring produced per nest was greatest in the park interior. Heavy use of, and apparent preference for, edge by nesting Spotted Towhees, coupled with high fledgling mortality near edges, created a severe ecological trap that was not apparent until the final stage of parental care. Hence, failure to document offspring survival in the late stages of reproduction may lead to incorrect assessment of habitat suitability and poor management decisions.
