A new method was used to prepare ABS/PA6 blends by in SITU POLYMERIZATION AND COMPATIBILIZATION method. In this process, e-caprolactam monomer was polymerized in presence of ABS via activated anionic POLYMERIZATION to produce PA6. The main ingredients of the reaction mixture included: monomer (e-caprolactam), catalyst (Na-caprolactamate), microactivator (HDI) AND macro-activator (SMA). Then, in different steps caprolactam/ABS composition, micro-activator AND macro-activator concentrations were selected as the variables. ABS/PA6 blends were prepared in an internal mixer (at 200oC) at three levels of ABS/caprolactam compositions (25/75, 50/50, 75/25), with varied concentrations of HDI (4 AND 6 phc) AND macro-activator (0, 3 AND 6 phc). As a result of all the variations the blends produced different morphologies. In samples with dispersed structure, the particle size reduced with higher macro-activator content. Also, the effect of macro-activator at lower level of HDI was more significant, probably due to the competition between the activators in the reaction. In some of the blends, dispersed particles with sizes under 100 nm were observed. The crystalline structure of PA6 phase was investigated using XRD AND DSC tests, which also showed changes with regard to initial composition AND activator contents. In pure samples only α-structure was detected, while in the blends of higher ABS content, g-form appeared AND at the ABS content of 75% only g-form was observed. The crystallinity decreased as the function of ABS content. Pure synthesized PA6 showed higher Tm AND Hc than the blends. The percentage crystallinity of the samples obtained from XRD AND DSC tests showed good correlation.

One may say that The Open Society AND Its Enemies (OS) offered in 1945 the first complete elaboration of the general approach proposed by Karl Popper, namely his ‘critical rationalism’, a bold generalization of the fallibilist falsificationism in the domain of the empirical sciences masterly proposed in Logik der Forschung (1934). The political content of The OS has been critically discussed. Nevertheless, not all people insist on the equally important moral dimension of the book, giving it its unity, I submit. Without morality, no critical discussion, no reason, no open society, let us say in a nutshell. I would argue that according to Popper, a strictly Christian morality of love would not be the appropriate emotional companion of critical rationalism, but that the less demANDing moral emotion of sympathy or compassion is perhaps necessary to give it its force against violence. I give some support to this line of argument. In my view, Popper proposed a somewhat unarticulated critical rationalist ‘emotivism’ of sorts. The emotion of compassion is necessary for triggering our moral decisions AND values, which are the ultimate basis of the choice for a reason against violence.

Bis (2-R-ind) ZrCl2 (R: H or phenyl) was supported on different types of silica by in SITU impregnation method AND used for ethylene POLYMERIZATION. In this method, the step of catalyst loading on support was eliminated AND common alkyl aluminum (triisobutylaluminum, TiBA) cocatalyst was used instead of expensive methyl aluminiumoxane (MAO) cocatalyst in the POLYMERIZATION. The effect of surface area of silica on the performance of the supported catalysts using three different types of silica including EP12 (390 m2/gr.), PQ3060 (570 m2/gr.) AND MCM-41 (1100 m2/gr.) was investigated. The surface area had a more critical role relative to other characteristics of the support in the performance of catalysts. By using MCM-41 as support, the kinetic stability was enhanced. The activity of the supported catalysts was increased by increasing the surface area of silica in the order of MCM-41>PQ3060>EP12. The morphology of polymer particles was improved AND reactor fouling was eliminated by supporting the catalyst.

Feed evaluation provides essential information’s to animal nutritionists for better feed formulation on the basis of physiological AND economical view of point to improve animal performance. There are various feed evaluation method at present time AND In SITU technique (nylon bag or in sacco method) is commonly used in this way. In this study, ruminal degradability of dry matter, organic matter, crude protein AND ADF was measured. Four different oil seed meals consist of canola meal, cotton seed meal, soybean meal AND sunflower meal was studied using in SITU method. Results of this experiment indicated that degradability (a+b) AND effective degradation (EP) in soybean meal, canola meal AND cotton seed meal produced in Behpak oil plant was (98.5, 98.7 AND 56.8%) AND (55.8, 62.0 AND 48.3%) AND for soybean meal, canola meal AND sunflower meal produced in kesht-o-sanat oil plant was (81.7, 90.1 AND 90.5%) AND (47.1, 52.5 AND 45.2%) respectively.

Novel hybrid inorganic/organic poly[cyclotriphosphazene-co-(hexafluoroisopropylidene)] nanotubes (PZTs) were synthesized through nucleophilic substitution using one-step method. The surface of PZTs contains hydroxyl AND fluorine groups with a ratio of approximately 1: 3, which imparts many functional properties to the nanotubes. The introduction of the active hydroxyl groups increased the chemical bond crosslinking between the nanotubes AND the matrix resin. The introduction of fluorine atom provided the hydrophobicity AND abrasion resistance properties. The water contact angle of PZTs is 140. 3°, . Chemical reaction occurred between WPU AND PZTs to form covalent bonds through in SITU POLYMERIZATION. The water contact angle AND thermal stability of waterborne polyurethane (WPU)/PZTs increased with the increasing nanotube content. When the nanotube content was 1. 0 wt%, the maximum tensile strength of the composites was 3. 36 MPa AND the maximum elongation-at-break was 446. 8%. The nanotubes showed toughening AND strengthening characteristics. When 1. 0 wt% PZTs were incorporated, the friction coefficient AND abrasion loss of the composites reached a minimum value. The addition of nanotubes could increase surface hardness AND crosslinking degree, absorb the coating heat of friction, AND reduce the adhesive wear of polymer AND the wear amount. The introduction of fluorine atoms could form a chemical transfer membrane AND reduce the friction coefficient. Polyphosphazene nanotubes showed excellent modification properties in the waterborne polyurethane system.

Due to having spring AND autumn genotypes AND adaptation to weather conditions, rapeseed is considered as a point hope to provide edible oil of country. Two separate experiments were set up as split-plot in a RCBD design with three replications in two fall AND winter seasons during two years (2014-2015 AND 2015-2016) at the research field of Seed AND Plant Improvement Institute to investigate the effect of sowing season AND date on the quantitative AND qualitative yields of rapeseed genotypes in Karaj, Iran. In this study, the main plots were sowing dates (7, 17, AND 27 October in fall sowing AND 9 AND 19 February, AND 1 March in winter sowings) AND sub-plots consisted of genotypes (RGS003, Dalgan, Zabol10, Hyola401, AND Hyola4815). Rapeseed genotypes grain AND oil yields were 4330 AND 1840 kg ha-1 in fall sowing, respectively, while these traits were decreased 43.3 AND 46.6% respectively, when rapeseed genotypes were planted in winter season. The highest grain AND oil yields (5033 AND 2202 kg ha-1) belonged to 7 October sowing date in fall sowing, while 9 February had the highest grain AND oil yields (2996 AND 1248 kg ha-1) in winter sowing. In general, the Dalgan genotype is recommended for cultivation due to suitable agronomic traits such as number of silique per plant, number of grain per silique, silique length, 1000-grain weight, as well as high grain AND oil yields in cold temperate regions with arid AND semi-arid climates such as Karaj, Iran.

Blends of linear low-density polyethylene (LLDPE)/poly(vinyl alcohol) (PVA) were prepared by conventional thermoplastic processing technique. The blends were mixed using a Haake rheometer at 150°C AND 50 rpm for 10 min. The LLDPE AND PVA were blended to give the following blend ratios (php): 90/10, 80/20, 60/40, 50/50 AND 40/60. The effect of maleic acid via in SITU cross-linking on processability, component interaction, miscibility, thermal stability, tensile properties, AND morphology of LLDPE/PVA blends was investigated in this research. The results indicated that the presence of maleic acid increases the equilibrium torque of LLDPE/PVA blends. This observation may be due to better compatibility AND cross-linking between LLDPE AND PVA. The formation of cross-linking was confirmed by Fourier transform infrared analysis AND depression of melting points of PVA AND LLDPE in the blends. The thermal stability AND mechanical properties such as tensile strength, elongation-atbreak, AND Young's modulus of the LLDPE/PVA blends also improved in the presence of maleic acid. Evidence for greater compatibility between LLDPE AND PVA was confirmed by emergence of elongated fibrils extending over the surface of the PVA dispersed phases in the LLDPE matrix as revealed by scanning electron microscopy micrographs.
