أثبتنا في هذا البحث أن أي مقاس -R يميني M هو مرافق مسطح. و نظمت أمثلة لمقاسات -R مرافق مسطحة غير تباينية ووجدنا أنه إذا كانـت R حلقـة . مرافـق مسطحة فإن كل مثالي يميني منتهي التوليد R هو إسقاطي، إذا و فقط إذا كان كل خارج من مقاس مرافق مسطح يميني هو مرافق مسطح يميني إذا و فقط إذا كان كل مثالي يميني منتهي التوليد إسقاطي بالنـسبة لمقاس مرافق مسطح يميني.
In this paper we prove that any right R-module M is coflat Here we find that if R is a right coflat ring, then every finitely generated right ideal is projective if and only if every quotient of right coflat R-module is right coflat if and only if every finitely generated right ideal is projective relative to right coflat R-module.

The research was carried out during 2009 – 2010 in Al – Hasaka – Amoda – to study the effect of cattle manure at the rate of 30 ton/h1, and four organic green fertilizers (Lentil, Vetch, Faba bean and Barely) on plant area and earliness properties of
cotton crop compared with chemical fertilizer 400 kg/h1 urea, 83 kg/h1 P2O5 and 25 kg/h1 K2O.The study showed that the cattle manure significantly increased (plant area, lower first fruiting branch, earliness of flowering and boll maturity) when compared with all studied fertilizers, the increase reached (190. 92 Cm2, 0.30 pod, 1.50 day and 0.90 day) respectively. When compared with chemical fertilizer, the legume green fertilizers (Lentil, Vetch and Faba bean) significantly increased the plant area when compared with the control. The legume green fertilizer (Lentil) significantly increased the earliness of flowering (2.73) day and boll maturity (2.21) day when compared with the green fertilizer (Barely). The chemical fertilizer did not significantly affect the earliness of flowering and boll maturity when compared with the legume green fertilizer (Lentil) during the two seasons.
This paper describes a general model of photovoltaic module. It can be used in all studies and researches
that focus on photovoltaic generator. The main advantage of this model is in using the general
specification of the module which is included in the datasheet.
In this paper, we studied the concept of semi-potency of
endomorphism ring of modules. In addition to that, it has been
studied the endomorphism ring of semi injective ( projective)
modules and direct injective ( projective) modules.

In this paper, the characterization of right and left quasi-Frobenius
categories, has been given.
Let C be a small preadditive category, C* the dual category of C. It has
shown, that the following conditions are equivalent:
(i) C is right and lef
t quasi-Frobenius;
(ii) All flat C-modules and all flat C*-modules are injective;
(iii) All injective C-modules and all injective C*-modules are projective.
Information extraction from documents has become great use of novel natural language processing areas. Most of the entity extraction methodologies are variant in a context such as medical area, financial area, also come even limited to the given lang
uage. It is better to have one generic approach applicable for any document type to extract entity information regardless of language, context, and structure. Also, another issue in such research is structural analysis while keeping the hierarchical, semantic, and heuristic features. Another problem identified is that usually, it requires a massive training corpus. Therefore, this research focus on mitigating such barriers. Several approaches have been identifying towards building document information extractors focusing on different disciplines. This research area involves natural language processing, semantic analysis, information extraction, and conceptual modelling. This paper presents a review of the information extraction mechanism to construct a generic framework for document extraction with aim of providing a solid base for upcoming research.
