Changing of Vegetative to Reproductive Ratio as a Response to Different Sowing Dates in Sunflower
Authors: Aliloo Ali Asghar 
Published: January 2018

AbstractSunflower is an important source for edible oils and biodiesel production. Its productivity is limited by many agronomical practices one of which is the sowing date. In this study, the effects of different sowing dates from early April to late June on phenology and yield of sunflower cultivars were investigated. The results showed that sunflower has a relatively long period of possible sowing dates, stretching from early April to late June in North West of Iran. However, delayed sowing dates significantly decreased the number of days needed for phenophases. For every day of delay, the model predicted (R2=0.97) a losing rate in achene yield by 22.2 kg h−1 from the first sowing date. For relationships between growing degree days (GDD) and yield, almost the same results were obtained. About 22 kg h−1 reduction (R2=0.79) in yield per day was estimated by GDD index when the average GDDs per day was 14.2. However, helio-thermal units (HTU) did not predict this reduction accurately. A suggested comprehensive model, that used the percent of yield losses and changes in vegetative to reproductive ratio, found a significant and positive relationship between the indices and yield losses. For all indices, an increase in vegetative to reproductive ratio resulted in increased grain yield losses.

Published: January 2018

AbstractWood of radiata pine (Pinus radiataDon) was treated with an aqueous styrene/acrylic acid (St/AA) copolymer dispersion leading to weight percent gains (WPGs) of 10–42%. The reactivity of St/AA in wood and the modifying effects on wood properties were investigated. The St/AA precipitated in the cell lumens and condensed under catalysis at elevated temperatures was shown via scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. Treatment did not cause positive bulking efficiency and anti-swelling efficiency, because St/AA cannot diffuse into the cell walls due to its high molecular mass. The modulus of elasticity and rupture (MOE and MOR, respectively), and the surface hardness of the wood were improved by 24.4, 22.2, and 40.6%, respectively. Compression strength increased by 81.6 and 48.2% in radial and longitudinal directions, but the impact strength was hardly influenced by the treatment. In addition, the treated wood was slightly more hydrophobic than untreated controls as shown by reduced moisture content and water uptake. Accordingly, treatment with St/AA leads to mechanical reinforcement of wood and enhances its water resistance, and as a consequence, it has an application potential to improve the wood quality.

Abstract
The individual and combined effects of W and Zr additions on macrostructure, microstructure and mechanical properties of Nb have been investigated. Nb, Nb-10 wt% W, Nb-2.5 wt% Zr and Nb-10 wt% W-2.5 wt% Zr alloy ingots were prepared by electron beam drip melting using high purity Nb, W and Zr rods. Additions of W and Zr resulted in significant improvement in hardness and room temperature tensile strength. It is seen that the effect of 10 wt% W addition is more than that of 2.5 wt% Zr addition in improving room temperature strength of Nb, although on ‘per wt% addition’ basis, Zr is a more effective strengthener than W. It is also observed that the cumulative effects of 10 wt% W and 2.5 wt% Zr on grain refinement and strengthening are more than their respective individual effects.
Development of kinetics sub-model of cyanate ester-based prepregs for autoclave molding process simulation
Authors: Maji Prosenjit , Neogi Swati 
Published: January 2018

Abstract
Autoclave molding of prepregs is an established fabrication method to produce composite components to be used in the aerospace industry and elsewhere. The process involves the excess resin to flow out and curing of the resin. The process model simulation, which is very effective to optimize the process parameters and laminate properties, requires various sub-models to account for resin flow and resin curing. This work focuses on the curing behavior and development of kinetic sub-model of a quartz fabric prepreg impregnated with cyanate ester-based resin. Differential scanning calorimetry (DSC) in both dynamic and isothermal modes has been used for the study. The dynamic study reveals that two distinct reaction mechanisms were involved during curing. The dynamic study data is used to obtain the activation energy using model-free iso-conversional method. The kinetic expression obtained using the isothermal DSC scan data is able to predict the complexity of the overall reaction which can be described by nth-order reaction kinetics for the initial phase of reaction followed by the autocatalytic reaction kinetics.
A Logistic Regression/Markov Chain Model for American College Football
Authors: Kolbush J. , Sokol J. 
Published: January 2018

Abstract
Kvam and Sokol developed a successful logistic regression/Markov chain (LRMC) model for ranking college basketball teams part of Division I of the National Colligate Athletic Association (NCAA). In their 2006 publication, they illustrated that the LRMC model is one of the most successful ranking systems in predicting the outcome of the NCAA Division I Basketball Tournament. However, it cannot directly be extended to college football because of the lack of home-and-home matchups that LRMC exploits in performing its Logistic Regression. We present a common-opponents-based approach that allows us to perform a Logistic Regression and thus create a football LRMC (F-LRMC) model. This approach compares the margin of victory of home teams to their winning percentage in games played against common-opponents with the away team. Computational results show that F-LRMC is among the best of the many ranking systems tracked by Massey's College Football Ranking Composite.

Abstract
The purpose of this study was twofold: 1) to discover the differences in degree of energy expenditure (EE) during Just Dance 2015 using Xbox 360 Kinect, Wii-U, PS3 Move, and Control YouTube video; and 2) to uncover whether or not exergaming could elicit moderate to vigorous levels of intensity (≥ 40% Heart Rate Reserve (HRR)) based on heart rate average (HRavg) measurements. Twenty-five healthy college-aged students participated in this study. Data collection was comprised of baseline testing, a 30 second familiarization period with each gaming console, and a gaming session. Participants danced to the song “Love Me Again” on a Just Dance 2015 program on Xbox 360 Kinect, Wii-U, PS3 Move, and a control YouTube. EE and HRR were calculated using FT4 Polar Heart Rate Monitor. One-way repeated measures ANOVA indicated no significant differences in energy expenditure across the consoles, F(2.74, 65.86)=0.65, p=.570. The paired samples t-test indicated the HRavg for the Xbox 360 Kinect (117±18 bpm) was significantly greater than the HRavg for the Control (112±16 bpm), t(24)=3.03, p=.006. About a third (28%-36%) of participants met moderate levels of intensity while exergaming. Dancing on all three major gaming consoles and YouTube video increase energy expenditures and can be used as an alternative form of exercise with the ability to achieve moderate levels of intensity.

Abstract
Most studies on the PAFSIN pipes were oriented monitoring their behavior in laboratory conditions, focusing on the fluid and less influence on the environment laying on the mechanical properties in the short term then extrapolated mathematical term. Moreover, a large part of these studies refer only to the effect on PAFSIN composite samples without taking into account the specificities induced specific geometry pipeline. In this way, the effect PAFSIN pipes can be overlooked, which in practice can lead to significant errors of design and / or execution. Compared to existing studies, taking into account only the effect of a sealant (generally standardized solutions of acid or base) of the PAFSIN pipes, in the article to present the results of tests conducted on PAFSIN pipes buried in different types of land and attempted to surprise the complexity of the interactions of soil solution to the conduit.
Beyond Geodesign: The Architecture of Sitesynthesis
Authors: Bianco Lino 
Published: January 2018

Abstract
This paper presents sustainable architecture as a function of sensory experience through time. Entitled sitesynthesis, this proposed approach forms the foundation of a holistic design methodology grounded physically in the geographical location of a given community and metaphysically in the spirit of place derived from sense experience. Sitesynthesis is made up of sitescapes which range from natural to cultural to social landscapes, themselves the product of the sensescapes through timescapes. The site is the place in geological, archaeological and historical time. The symbiotic relationship between the natural, cultural and social environs which sitesynthesis endeavours to attain is mutualistic rather than parasitic, a relationship from which society and the site both benefit rather than the former benefiting at the expense of the latter.

Published: January 2018

Abstract
In the present study, as the calculation of forces on the cylindrical structures of the sea has a special complexity, Morrison's mathematical model was used in the software. In addition, the kinematics of water particles is estimated to calculate their acceleration from the fifth-order non-static wave theory (Fenton method). In this paper, the analysis of the pier performance considering structural-fluid interaction using ANSYS soft is presented. Five models with the same period were considered and different wave heights and two different earthquake records of Tabas and Northwich were studied. Finally, node displacement, acceleration and reciprocal interaction forces were extracted and compared with the numerical values. The results indicated that the values of the studied parameters and the type of nodes were similar in the models without a record of earthquakes, but with the estimation of the earthquake, these values would be significant.

Abstract
“Light well” as one of the most common means of daylight tolls in building, experiences severe limitations and deserve special attention. The question is which strategy is the best for increasing the daylight penetration to the depth of buildings. One of the main challenges in deep plan is to guide daylight into the building core and this can be performed through daylighting strategies, but the choice of the proper innovative daylighting system (IDS) with several parameters is the problem. This paper aims to find elements for optimal choice and selecting context-compatible tools for light well. The result shows that four macro factors were found at the interaction of building and IDS. Identifying the integration components can play an effective role in decision-making or design a new tolls consistent with the physical conditions of light well and building to overcome the daylight crisis.

AbstractRoller Compacted Concrete (RCC) dams are actually a combination of concrete dams' safety and procedure of earth dam while accelerating construction and reducing administrative costs, have high safety. And why in the world and Iran, constructing this type of dam has growing trend. The first roller compacted concrete (RCC) dam of Iran (Jegin dam) has come into operation in 2006. In terms of expressed statistics and given that, none of these dams has not been subject to severe earthquake, roller concrete dam operations is not specified in facing with severe earthquake and its merits and faults. Therefore, the need for seismic analysis of these dams in the design, implementation and operation is obvious. In the meantime, the lack of studies on how modeling of roller compacted concrete (RCC) dams using finite element software, especially on how to foundation modeling (dimensions, material properties, interaction of foundation and dam), modeling dam lake (the length of lake, the water level, the interaction between the lake and the dam body) felt. In this study, dynamic analysis of roller compacted concrete (RCC) dam using ABAQUS finite element software and modeling one of the roller compacted concrete (RCC) dams of Malaysia with the change approach of foundation boundary conditions will be considered.

Published: January 2018

Abstract
Digital Elevation Models have been an important topic in the last decades in order to accurately describe one’s surroundings for various purposes. The most wide-spread applications of Digital Elevation Modelling are related to volumetric calculations over large areas, as well as to hydrographic simulations. This paper will analyse the impact of various data interpolation models on the result of volumetric calculations in a longitudinal shaped polder. In order to achieve general conclusions instead of case specific solutions, the raw parametric Digital Elevation Models have been used, rather than the specific parameters suiting the actual scenario. In order to achieve this, data smoothing has also been neglected. The result of the conducted study presents the impact of the digital elevation modelling methods over the volumetric calculations. When applied to the same dataset, the methods yielded different results, partially confirming the predicted usefulness of the algorithms.

Published: January 2018

Abstract
The strengthening of professional identity (PI) of teachers of higher education institutions (HEI) is one of the ways to improve the quality of educational process. Performance of professional role(s) can be identified as the key component of PI. The contemporary university teacher performs many professional roles: she/he is a lecturer, researcher, supervisor of students’ research works, expert, and so on. Multi-role activity of a teacher is considered as a characteristic feature of the profession by the colleagues in Latvia, Russia and other countries. This research is based on the data obtained during the implementation of the Project ‘Professional Identity of Contemporary Pedagogue’ in 2014–2016 by the researchers from Riga (Latvia) and Smolensk (Russia). In the realization of the project, the six-component structural model of the content of HEI teacher’s PI was created and the survey was carried out using the questionnaire ‘HEI Teachers’ Professional Identity’ developed by the project participants. Overall, a total of 198 teachers were surveyed in Riga and Smolensk. The aim of this article was to analyze and compare the data obtained for the PI component ‘Professional Roles’ in the samples of HEI teachers of both the countries. The data were analysed using statistical methods. The results showed that teachers of both the countries perform their professional roles at a high level. Overall, the answers of teachers of the two countries were well agreed. However, some peculiarities in the data of Riga and Smolensk were observed, and some problems of PI of HEI teachers were identified, which require attention of executives of the education reform and teachers.

Published: January 2018

Abstract
The past decade constitutes a significant turning point in the orientation of policy makers in the Israeli educational system. This period is characterized by comprehensive structural and pedagogical reforms intended for the promotion of the system’s achievements. ‘Pedagogical Flexibility’, a reform in the professional development of teaching staff implemented in 2015, constitutes a significant breakthrough in the perception of development and learning in Israel. The school principals play a main role in leading the reform and in the development of a new organizational culture in the staff as well. This led to the creation of focused learning frameworks for school principals who sought to improve their knowledge and skill in the leadership of the reform. The article presents the main points of the first pilot program implemented in the North District for the training of 20 school principals in the reform and the main findings from the evaluation of the program, data from a questionnaire, and a focus group. In addition, the article proposes a critical look at the program effectiveness and indicates further focuses for future learning. The article presents a view of the role of the school principal in the leadership of the professional development in Israel and reviews theoretical aspects that arise from the research regarding this issue.
Compensation for Those Indirectly Affected by the Death of a Household Member
Authors: Jędrzychowska Anna 
Published: January 2018

Abstract
This article demonstrates the size of the budget gap that arises in a household after the death of that member who was the breadwinner of the family. It also describes how this gap can be covered by motor vehicle liability insurance. One source of funding for this gap could be, for example, an annuity for indirect victims. In many EU countries, people who are members of the household of the deceased are considered to be affected as a result of his death. Those indirectly affected will include the family members and relatives of the deceased (spouse, parent, child, sibling, and cohabitant). The person responsible for the death should pay compensation to the family members of the deceased. One of the elements determining this compensation should be the loss of income to the family of the deceased. The second element is compensation for the lost personal contribution. This paper presents the study of literature as an introduction to the relevant issues. The problem of compensation for lost income will be illustrated by legal regulations and calculations based on the account actuarial-term annuity. The study focuses on the selected EU countries. This article is part of a broader study by the author on the material consequences of personal injury and sources of their financing.
