This study has been carried out in  Alkut city the center of Wasit province which is located about 180 km south of the capital Baghdad on one from the most important dams constructed on theriverTigris called Alkut Dam  .Four pedons have been selected in this study, two pedons (A,B) are located in  the lower part of dam and the other two pedons (C ,D) are located in the upper part of dam ,  sediments samples analysis for particle  size distribution  and  total  & available  heavy metals concentration (Ni ، Cd ، Zn ، Pb ،Fe) in the water and sediments. Results show that the total concentration of nickel ranges between(104.2 - 178.4) mg.kg-1and the higher value has been found in the second depth (156-126)cm for pedon A  and the lower value has been found in the second depth (50-30) for pedon D ,  while total cadmium concentration ranges between (6.1-2.2)mg.kg-1and the higher value has been found in the second depth (35-20) for pedon A at the lower part of dam  and the lower value has been found in the sixth depth (73-93cm)for the same pedon , the values for total Zinc concentration ranges between  (108-69) mg.kg-1 and the higher value has been found in the fifth depth (73-55)cm for pedon A at the lower part of dam  and the lower value has been found in the last depth (120-100cm) for  pedonD in the upper part of dam, the results of total lead concentration ranges between  (24.2-11.35) mg.kg-1 and the higher value has been found in the first depth (0-20cm)cm for pedon A at the lower part of dam  and the lower value has been found in the third depth (60-50cm) for  pedonD in the upper part of dam ,  while the total concentration for  iron (Fe) which  ranges between (4595-2988) mg.kg-1 the higher value has been found in the second depth (20-50cm) for pedon A at the lower part of dam  and the lower value has been found in the seventh depth (111-93cm) for  the same pedon .As compared with critical limits , results show that total concentration of heavy metals  for Cd, Pb, Zn and Ni in Sediments samples all has exceed the critical limits values  except in some depths. The results for the available heavy metal concentrations show that the available nickel concentration ranges between(33.2-107.4)mg.kg-1 and the higher value has been found in the second   depth (20-35)cm for pedon A at the lower part of dam  and the lower value has been found in the second  depth (30-50) for  pedonD in the upper part of dam,while total cadmium concentration ranges between (0.21-0.48)mg.kg-1and the higher value has been found in the first depth (0-20)cm for pedon B at the lower part of dam  and the lower value has been found in the sixth depth (73-93cm)for the pedon A at the lower part of dam ,  the values for the available Zinc concentration ranges between  (56-111) mg.kg-1 and the higher value has been found in the tenth depth (191-231)cm for pedon A at the lower part of dam  and the lower value has been found in the last depth (120-100cm) for  pedonD in the upper part of dam, the results of available  lead (pb) concentration ranges between  (6.7-20.2) mg.kg-1 and the higher value has been found in the first depth (0-20cm)cm for pedon A at the lower part of dam  and the lower value has been found in the third depth (60-50cm) for  pedonD in the upper part of dam ,  while the available concentration for  iron (Fe) which  ranges between (39-74)mg.kg-1 the higher value has been found in the second depth (20-50cm) for pedon A at the lower part of dam  and the lower value has been found in the eighth  depth(111-126) for  the same pedon,at the comparison of results for the available concentrations of the studied heavy metals it can be seenthat all values have exceeded the critical limits values  according to Nunes etal 2014. in the other hand the results show that there is significant correlation between the total and available concentration for same heavy metalspairs of the correlation  (r2) between the available and total  concentration  was 0.90 ,  0.74 , 0.99, 0.99 and 0.58 for Ni , Cd , Zn , Pb  and Fe respectively , in the other hand, the results show that the water concentration for heavy  metals are 1.7 , 0.03  ,15 , 0.07 and  27 mg.l-1for Ni , Cd , Zn , Pb  and Fe respectively , which indicate that all   values  have  exceeded the  critical limits according to  Iraqi standards and  FAW.

New Settlements

The 3rd millennium BC appears to be a key period of development of the historical settlement landscape in ancient Egypt. After the unification of the country, the process of disappearance of the predynastic socio-political structures and settlement patterns associated with them significantly accelerated. Old chiefdoms, along with their centres and elites, declined and vanished. On the other hand, new settlements emerging in various parts of the country were often strictly related to the central authorities and formation of the new territorial administration. Not negligible were climatic changes, which influenced the shifting of the ecumene. Although these changes were evolutionary in their nature, some important stages may be recognized. According to data obtained during surveys and excavations, there are a number of sites that were considerably impoverished and/or abandoned before and at the beginning of the Old Kingdom. On the other hand, during the Third and Fourth Dynasties some important Egyptian settlements have emerged in the sources and begun their prosperity. Architectural remains as well as written sources indicate the growing interest of the state in the hierarchy of landscape elements and territorial structure of the country.

The aim of this work was to evaluate the potential of ultrasound (US), alone or in combination with mild heating and/or EDTA towards reduction of As, Cd, I, and Hg content of Laminaria hyperborea. Concentrations of As, Cd, I, and Hg of 56.29, 0.596, 7340, and <0.01 mg kg−1 of dry weight, respectively, were found in L. hyperborea blades. Treatment with US at 50 °C increased approx. 2-fold the amount of As released, although did not affect significantly the content of Cd or I, as compared to control (no US) samples. Reducing the temperature to 8 °C significantly decreased the effect of US, but heating at 80 °C did not cause a significant effect as compared to treatments at 50 °C. On the other hand, treatment with 0.1 N EDTA at 50 °C enhanced the percentage of Cd released by approximately 7-fold, regardless of sonication. In the present work, the combination of US and EDTA at 50 °C for 5 min led to a significant reduction of the As (32%), Cd (52%) and I (31%) content in L. hyperborea, thus improving the product’s safety for consumers.

The difference between intent (dolus) and negligence (culpa) was rarely emphasized in codified medieval laws and regulations. When compared to the legal statements related to intent, negligence was mentioned even more rarely. However, there are some laws that distinguished between the two concepts in terms of some specific crimes, such as arson. This paper draws attention to three medieval Slavic legal documents – the Zakon Sudnyj LJudem (ZSLJ), the Vinodol Law and the Statute of Senj. They are compared with reference to regulations regarding arson, with the focus being on arson as a crime committed intentionally or out of negligence. The ZSLJ as the oldest known Slavic law in the world shows some similarities with other medieval Slavic legal codes, especially in the field of criminal law, since most of the ZSLJ’s articles are related to criminal law. On the other hand, the Vinodol Law is the oldest preserved Croatian law and it is among the oldest Slavic codes in the world. It was written in 1288 in the Croatian Glagolitic script and in the Croatian Chakavian dialect. The third document – the Statute of Senj – regulated legal matters in the Croatian littoral town of Senj. It was written in 1388 – exactly a century after the Vinodol Law was proclaimed. When comparing the Vinodol Law and the Statute of Senj with the Zakon Sudnyj LJudem, there are clear differences and similarities, particularly in the field of criminal law. Within the framework of criminal offenses, the act of arson is important for making a distinction between intent and negligence. While the ZSLJ regulates different levels of guilt, the Vinodol Law makes no difference between dolus and culpa. On the other hand, the Statute of Senj strictly refers to negligence as a punishable crime. Even though the ZSLJ is almost half a millennium older than the Statute of Senj and around 400 years older than the Vinodol Law, this paper proves that the ZSLJ defines the guilt and the punishment for arson much better than the other two laws.

Thirty-six local dose have been used and were divided in to three groups sacording to weight, in each group twelve dose. In the first group the weights of the dose were higher than ( 2.5 kgs) and less than (3 kgs). The second groups was higher than 3 kgs) and less than (3.5 kgs). The third group was higher than (3.5 kgs) and less than (4 kgs). The aim of this study was to obtain the effect of doe weight on her reproductive efficiency (gestation period, litter size, litter weight at birth and weaning, growth rate of offspring preweaning, conception rate and preweaning mortility).  The weight of the doe had no significant effect upon the gestation period and this period was 30.9, 31.2, 31.3 days for the three groups respectively, on the other hand the litter size was affected significantly by doe weight and litter size was at birth and preaweaning (5.1 , 5.8 and 6.2), (4.5, 5.3 and 5.7) for the three groups respectively. The offspring weight at birth and weaning was affected significantly by doe weight and this weight was (40.1 , 48.2 and 53.3 gms), (203.6, 227.5 and 233.8 gms) for the three groups respectively while the conception rate was not affected by doe weight. The mortility percentage in the prewaning period was not significantly by doe weight

Textual Strategies

This study is dealing with two Hungarian translations of Euripides’ Medea. The translation made by Grácia Kerényi was produced in the second half of the 20th century, whereas the version by Zsuzsa Rakovszky was published at the beginning of the 21st. The difference between the translations regarding their textual strategies, the professional background of the translators and the final goal of the works is abysmal. Grácia Kerényi was an expert of ancient literatures, her translation was published in the official and renowned collection of Euripides’ work, Zsuzsa Rakovszky on the other hand translates predominantly from English, and her version was inspired by the request of the theatre. The study contains three parts: in the first the author analyses Kerényi’s Medea in the context of the philological reconstruction, in the second, the author examines the same text modified and revised by Fruzsina Magyar, who was the dramatic advisor of the theatre performance in Szolnok, and the third part reflects on the problems of validity, poetical force and immediacy in the translation of Zsuzsa Rakovszky.

We study an elimination tournament with four contestants, each of whom has either a high value of winning (a strong player) or a low value of winning (a weak player) and these values are common knowledge. Each pairwise match is modeled as an all-pay auction. The winners of the first stage (semifinal) compete in the second stage (final) for the first prize, while the losers of the first stage compete for the third prize. We examine whether or not the game for the third prize is profitable for the designer who wishes to maximize the total effort of the players. We demonstrate that if the players are asymmetric and there are at least two strong players, then there is always a seeding of the players such that the third place game is not profitable. On the other hand, if there are at least two weak players, then there is always a seeding of the players such that the third place game is profitable.

Mebendazole, albendazole, levamisole and thiabendazole are well known as active drugs against several nematode species, and against cestodes as well, when the first two drugs are considered. None of the drugs have proven activity, however, against trematodes. We tested the effect of these drugs on the fecal shedding of schistosome eggs and the recovering of adult schistosomes, after portal perfusion in Schistosoma mansoni experimentally infected mice. Balb/c mice infected with 80 S. mansoni cercariae were divided into three groups, each in turn subdivided into four other groups, for each tested drug. The first group was treated with each one of the studied drugs 25 days after S. mansoni infection; the second group was submitted to treatment with each one of the drugs 60 days after infection. Finally, the third group, considered as control, received no treatment. No effect upon fecal shedding of S. mansoni eggs and recovering of schistosomes after portal perfusion was observed when mice were treated with either mebendazole or albendazole. Mice treated with either levamisole or thiabendazole, on the other hand, showed a significant reduction in the recovering of adult schistosomes after portal perfusion, mainly when both drugs were given during the schistosomula evolution period, i.e., 25 days after cercariae penetration, probably due to unspecific immunomodulation

Bioplastics constitute a great opportunity for agriculture, industry and environment. On the one hand, the basic raw material used to fabricate bioplastics is made from renewable agricultural materials, on the other hand, bioplastics have a wide application as packaging and protections in the food and non-food industry as catering products as protection films and foils and as compostable items in agriculture. Also very important is that after achieving the purpose for which they are produced, bioplastics become waste and their cycle is closed as they can be used as compost for agriculture.

First Order Predicate Logic

The aim of this article is to present a method of creating deontic logics as axiomatic theories built on first-order predicate logic with identity. In the article, these theories are constructed as theories of legal events or as theories of acts. Legal events are understood as sequences (strings) of elementary situations in Wolniewicz′s sense. On the other hand, acts are understood as two-element legal events: the first element of a sequence is a choice situation (a situation that will be changed by an act), and the second element of this sequence is a chosen situation (a situation that arises as a result of that act). In this approach, legal rules (i.e., orders, bans, permits) are treated as sets of legal events. The article presents four deontic systems for legal events: AEP, AEPF, AEPOF, AEPOFI. In the first system, all legal events are permitted; in the second, they are permitted or forbidden; in the third, they are permitted, ordered or forbidden; and in the fourth, they are permitted, ordered, forbidden or irrelevant. Then, we present a deontic logic for acts (AAPOF), in which every act is permitted, ordered or forbidden. The theorems of this logic reflect deontic relations between acts as well as between acts and their parts. The direct inspiration to develop the approach presented in the article was the book Ontology of Situations by Boguslaw Wolniewicz, and indirectly, Wittgenstein’s Tractatus Logico-Philosophicus.

This chapter presents a sermon by Maurice N. Eisendrath, delivered on the third Rosh Hashanah of the war. The situation of Canadian rabbis was precariously positioned between those of American preachers to the south and British preachers to the east. Canada, as part of the British Commonwealth, had long been part of the war effort, so the debate over whether or not to enter the war was not an issue, as it still was for colleagues in the United States. On the other hand, Canada was not directly affected by the war as was Britain, where one year earlier London had suffered a sustained air attack unprecedented in its devastation (a situation that certainly affected the mood in Toronto on the previous Rosh Hashanah, as the preacher reminds his listeners). Now, although the battles on the recently opened Eastern Front were of almost unimaginable ferocity, to many Canadians the war seemed distant; life at home seemed almost normal, as it did to many in the United States. This was precisely the mindset that Eisendrath set out to censure.
