Abstract

Modeling of a Sport Utility Vehicle as it moves on two wheels studied in this paper. Our major purpose concentrated on developing a general criterion to specify rollover threshold. First, model of vehicle as it sustained on two wheels derived that its results used to develop rollover threshold of Sport Utility Vehicles. In addition, these results could be valuable to design new controllers, which are able to prevent rollover at the best state of vehicle dynamics. After vehicle modeling, appropriate model for tire forces and moments picked up from the most related and available references. Then validation accomplished as final part of modeling section. Stability of presented model studied as an important part of this paper. In order to specify rollover threshold as vehicle moves on two wheels, steady-state equations of motion used and based on steady state analyses a new criterion proposed. Next, by designing some maneuvers, simulations accomplished to show applicability of proposed criterion at different situations. As conclusion, presented criterion is more implementable and efficient than other proposed model for rollover threshold and can prospect rollover threshold at various steering angles and longitudinal speeds as model inputs.

Abstract

Defamation is prohibited in the international system of human rights and in domestic legal systems. Prohibition of defamation in domestic legal systems is explicit, but not in the international documents of human rights. Given that defamation causes damage to the reputation of people, and international instruments including the Covenant on Civil and Political Rights, European Convention on Human Rights, American Convention on Human Rights and African Charter on Human and Peoples' Rights have emphasized to respect the rights or reputation of others in the enjoyment of human rights, especially the right to freedom of expression, no body hesitated in banning defamation. Unfortunately, we see differences on the components of this legal concept, which can obscure the concept and range of defamation, and thus pave the way to abuse of libel laws. This disagreement also can be seen in the choice between criminal and civil laws dealing with libel. It is hopeful that the international system and domestic legal systems have accepted almost the same defenses against libel charges. Acceptance of these defenses is such that prevent, unauthorized damage to the rights and reputation of others and, at the same time, prevents violation of the right to freedom of expression. These defenses, especially, ensure the rights of those accused of libel against public officials and governmental bodies.

Abstract

Hate speech that can briefly be defined as advocacy of hate and hatred based on nationality, race or religion, possesses a special situation in international law. Even a specific type of these speeches that leads to genocide is one of the few international crimes along with war crimes and crimes against humanity. Some events of the recent decades indicate that the racist movements, with the hate speeches as their main motive, are expanding in the world and even in the Europe that is supposed to be the pioneer of the human rights movement. This indicates the need for and the importance of discussion about this issue. This necessity has led that, besides the general prohibitions on the freedom of expression in the international instruments of human rights, some of the documents, including the International Covenant on Civil and Political Rights and the International Convention on the Elimination of All Forms of Racial Discrimination have specifically mentioned the prohibition of these speeches. However, the international instruments have been divided in defining this concept. This difference that especially is between the International Convention on the Elimination of All Forms of Racial Discrimination on the one side and other international instruments on the other has increased the importance of this concept's understanding.

Abstract

The aim of this study was to investigate the properties of polyethylene antimicrobial film containing niacin and limonene microcapsules in cheese process packaging. In this study microcapsules containing nisin (0.5, 1, 1.5, 2 and 2.5) and limonene (5, 7, 10, 14, 21 and 28 µg / mg) were prepared by gelation method. . After optimization, niacin and limonene microcapsules were used in polyethylene film based film formulation. After packaging cheese cheese in the film containing optimized microcapsules containing concentrations (1, 1.5 and 2 µg / mg nisin and 5, 7 and 10 µg / mg limonene), total microbial populations, mold and Yeast, Staphylococcus coagulase positive, Escherichia coli were examined on the first days of production, 20th, 40th, and 60th storage.
The results were analyzed by two-way ANOVA and Duncan tests at the significant level of 0.05. During 60 days of storage, total microbial indices, mildew and yeast, Staphylococcus coagulas positive and Escherichia coli significantly decreased (p≤0.05).
 The results showed that treatment with Nisin containing 2 IU / mg concentration and limonene with concentration of 10 µg / mg resulted in higher quality of processed cheese during storage period and were selected as optimal treatment.

Abstract

The aim of this study was to investigate the effect of natural antioxidant properties of crocetin and bixin on nanoparticle formulation of cheddar cheese. In this study, chitosan / alginate nanoparticles containing bixin (14, 16 and 18 μg / ml) and crocetin (0.01, 0.03 and 0.05 μg / ml) were prepared by gelation method. After preparation of cheddar cheese and addition of nanoparticles, total microbial population test was evaluated on the 1st day of production, 20th, 40th and 60th storage. The results were analyzed by two-way ANOVA and Duncan tests at the significant level of 0.05. The results showed that the total microbial population increased significantly during storage, but the total microbial population index decreased significantly with increasing levels of Bixin and Crocetin nanoparticles. Evaluation of sensory evaluation results showed a decrease in sensory evaluation scores over 60 days of storage. However, in the treatments with 18 μg / ml Bixin and Crocetin the sensory index changes were less than the other treatments. Finally, the treatment with 16 µg / ml bauxin and 0.05 µg / ml crocetin was selected as the optimal treatment.
