In this paper,, in order to know more about algebraic structures, is tried by adding Conditions to groupoids, RM-algebras, (involutive) moons and goops. some properties and relationships between them are investigated. It proven that in most cases, moons will be trivial with the addition of these Conditions.

The Additional Conditions are relatively new legal institution that have a special place in today's complex transactions and are based on the principle of autonomy and freedom of contract used by individuals in contracts. Islamic jurists and legal scholars have different views on the nature, validity, nullity and effects of these terms. While some regard them as basically null and void or as elementary Conditions, another group regards they are binding like Conditions stipulated in the contracts. Reviewing the nature and effects of these types of Conditions and relying on absolute jurisprudential principles, this study proves that are binding terms and Conditions.

In contrast to other ancillary suits (such as competing claims, compulsory presence of a third party, and intervention of a third party), there are no particular regulations in the Iranian Civil Procedural Law to define principles and rules govering “Additional claim”. The word “Additional” within the context of this term has two meanings. Its general meaning includes any change in the essential elements of the claim, the purpose of the claim, and the reason for the claim, which generally known as “changes in the claim”. In its specific meaning, it refers to a claim submitted under a new demand which is attached to the original claim due to its relation to the original claim. Accordingly, this paper analyses the concept, necessity, Conditions and rules govering the Additional claim in order to clarify the existing ambiguous points, differences and similarities with the changes in the claim.

Hand made rug is one of the major non-petroleum exported items which directly and indirectly supports the employment of large number of people around 8 to 9 millions in the recent years. The exportation of hand-made carpet has descended and it is considered a serious threat and may end to unemployment for a large number of the countrymen. This is one of the important reasons for the extra decrease of the carpet value. In this regard, the ordinary carpet in Hamedan and Fars and tiny weaved carpet in Isfahan have been investigated. The carpet under the investigation in Hamedan province is of rural woven type, in Fars province is Kashkooli woven type and in Isfahan's is 3\4-meter type. The selection of these carpets is according to the experienced expert and the frequency of that type of carpet in the mentioned provinces .The data collection was performed through the questionnaire. The number of samples for each province was assigned at the level of 40" .Then the samples were randomly selected. After the data collection related to production expenditures, the expenditures divided into direct and indirect ones. The direct expenditures consisted of elementary materials and direct wages, and indirect expenditures consisted of electricity, water, rental, and asset. When the expenditure means were assigned, the carpet sale price was computed too. Then the Additional value was investigated on the two Conditions of self-employment and management. Also, the type of production management was assigned based on the Additional value. The results indicated that the Additional value on the condition of self-employment and management in Hamedan province for rural carpet is equal to 37726 and 140707 and in Isfahan province for 3\4 meter type is equal to 82050 and, 161508, and in Fars province for tribal Kashkooli for each meter is equal to 4177 and 28138.

Standard-form contracts drafters try to prepare all the necessary terms and Conditions, which are a set of business customs, in the contract form; however, these efforts may not satisfy the parties. They have a right to add agreed terms and Conditions, which do not exist in the sample form, to the text of the contract, or, if these terms are too detailed, the clauses will be attached to the contract. They may also omit or replace some of the words and phrases in the sample contract. Such changes may lead to conflicts between the text of the standard-form contract and the supplementary phrases, which sometimes cannot be resolved without removing one of them. Also, if a word or phrase is removed from the standard-form contract, the question is whether the parties merely want the deleted phrase not to be part of the agreement or whether these omissions will provide meaningful feedback. With the aim of achieving mutual intention of the parties, the judges resolve the conflict by preferring Additional phrases and interpret the ambiguities of the remaining text of the standard-form contract by using the deleted words. Since the courts face challenges in this regard, this article tries to study the differences or unconsidered points and provide an appropriate solution.

The present research studied the (causal, contextual, and intervening) Conditions, strategies, and consequences of violence in the lives of child wives in Chabahar city, conducted with a qualitative methodology based on grounded theory. For this purpose, in-depth semi-structured interviews were conducted with 28 child-married girls in Chabahar city who were selected through theoretical sampling and snowball method. The analysis of the data in the framework of the three-level open, axial and selective coding system showed that gendered inequality and discrimination, women's inferiority, men's value, the culture of silence and the culture of violence play a role in the experience of child-wives in terms of violence (causal Conditions), which leads to a type of increased, double violence for them (core category); violence that operates within the framework of the family institution, the main mechanism of which are previous traditions and rules, and the perpetrators of which are men and women who were themselves the victims of the same traditions and rules that they have, now, internalized and used again against their daughters. This increased violence happens in a context where patriarchy is widespread (contextual Conditions) and due to the generalized self-deprecation among child wives (intervening Conditions), they may attempt to escape, get separated, threaten, and commit suicide (strategies), and these actions have consequences such as symbolic, physical, and sexual violence and even social isolation (consequences).

In this study, weather Conditions such as air humidity, temperature air, and wind speed were investigated in relation to wind turbine efficiency with the approach of an exergy study. In this study, the wind speed has been investigated in two different climatic regions of Iran with an approximate distance of 1200 km, in the names of Ardabil and Marvast. The amount of wind density of Ardabil is equal to 66 (kW/m2) and Marvast is equal to 123 (kW/m2). Power production using a 10 (Kw) wind turbine in the Ardabil region is 2.3 (MWh) and in the Marvast region is 3.2 (MWh) per year. The highest wind turbine exergy efficiency is 0.48 in the Ardabil region, and the highest exergy efficiency in the Marvast region is 0.18. The amount of reduction of CO2 gas production, using wind turbines in comparison to gas and diesel power plants in Ardabil, are 1.1 and 2.1 tons and in Marvast are 1.5 and 2.9 tons per year. This reduction in CO2 greenhouse gas per year is equal to using a forest region of 1000 (m2) to 3000 (m2). The use of wind turbines reduces the fuel consumption of diesel power plants in the Ardabil region for the amount of 797.4 liters and in the Marvast region for the amount of 1244 liters of diesel per year. According to this review, it can be concluded that in addition to wind speed, air humidity plays a significant role in the selection, installation, and commissioning of wind turbines in the region. According to this survey, it can be seen that in the Ardabil region, the wind speed of the wind turbine has a higher exergy efficiency than in the Marvast region, and it can be concluded that the wind turbine has performed better in the Ardabil region.
