Abstract

In this paper we introduce G-Rad-lifting module as aproper generalization of lifting module, some properties of this type of modules are investigated. We prove that if M is G-Rad- lifting and , then , and are G-Rad- lifting, hence we Conclude the direct summand of G-Rad- lifting is also G-Rad- lifting. Also we prove that if M is a duo module with and are G- Rad- lifting then M is G-Rad- lifting.

في هذا البحث سوف ندرس مقاسات الرفع المعممة من النمط Radical كتعميم لمقاسات الرفع. ونبرهن بعض خواص هذا النوع من المقاسات حيث سنبرهن انه اذا كان M مقاس رفع من النمط G-Rad ، وكان فإن مقاسات رفع من النمط G-Rad ، وعليه يكون كل جمع مباشر من مقاس من النمط G-Rad هو ايضاً مقاس من النمط G-Rad ، ايضاً سوف نبرهن بشروط اضافية انه اذا كان وكان مقاسا رفع من النمط G-Rad فان M هو مقاس رفع من النمط G-Rad.

Abstract

Let R be an associative ring with identity, and let M be a unitary left R-module. The main purpose of this paper is to introduce and study properties of class of modules including lifting module. We use the Radical submodule to introduce this class of modules. We start by defining a generalized lifting module as a generalization of lifting module, then we give another generalization of generalized lifting module we called it cofinitely generalized lifting module. Thus, we give characterization and prove some properties of this type of modules.

Abstract

Recall that an R-module M is lifting if every submodule of M lies above a direct summand of M. In this paper, we introduce and study the classes of modules which are extremity of lifting modules. We call an R-module M is strongly lifting if every submodule of M lies above a stable direct summand of M. Also, we call R-module M is S-lifting if every stable submodule of M lies above a direct summand of M. In fact, the following proper hierarchy is concluded: Strongly lifting modules Lifting modules S-lifting modulesSome counter examples are given to separate these concepts. Also, many characterizations and properties of strongly lifting (respectively, S-lifting) modules are obtain. It is shown that a module M is strongly lifting if and only if M is lifting and M is SS-modules. Moreover, we investigate whether the class of strongly lifting (respectively, S-lifting) modules are closed under particular class of submodules, direct summands and direct sums. It shown that a finite direct sum of S-lifting modules is S-lifting.

Abstract

Abstract In this paper, the design of new real time integer to integer lifting based wavelet transform IWT architecture is focused. An efficient design method is proposed to construct an integrated programmable VLSI architecture that can operate as forward or backward IWT in pipeline fashion. The layout VLSI integrated structure is simple, modular, and cascadable for computation of wavelet transform based on 5/3 biorthogonal filters. The architecture is optimal with respect to both area and time and independent of the size of the input signal without necessitate to memory. The lifting steps adapted to be causal and the proposed architecture is suitable to be used in the real time processing applications. The critical path of the architecture is equal to critical path of one lifting step. The numerical precision has been established using simulink model. Experimental tests have been made with 8-bit signed two's complement integer numbers. Based on the experimental result observations, the data path width of proposed architecture is fixed at 10 bits.Keywords: Lifting scheme, VLSI architecture, wavelet transform.

Abstract

the raising of voice on some occasions Islamic rituals such as raising it in calling for prayers, pilgrimage and leadership. Nevertheless Islam prevents the raising of voice for women while calling for prayers or their leadership in the presence of men. The study deals with various subjects and points out the jurists points of view: 1.Raising the voice in calling for the prayer is an assured convention putting into consideration the selection of those whose voice is vigorous. 2.Calling for prayer is forbidden for women in the presence of men. That will lead to charisma. 3.It is preferable to raise the voice for the men while doing the pilgrimage rite in order to expose the vigour of the Muslims. 4.The non-raising of the voice while reciting the Holy Quran. 5.It is preferable to raise the voice in nights of the two Eids ore while going to their prayers putting into consideration that over-raising is prohibited. 6.The voice is not to be raised during the escort of the dead. Calmness is better for them. 7.It is preferable to have sonority of voice if hypocrisy is safe guarded and when such sonority leads to remind the inattentive. Thanks for Almighty Allah

الحمد لله رب العالمين، وأفضل الصلاة والسلام على أشرف الخلق سيدنا محمد خاتم الأنبياء والمرسلين وعلى آله وصحبه الذين خاطبهم وأمرهم بعدم رفع صوتهم في حضرته ، وفي المقابل أباح لنا الشارع رفع الصوت في مواطن كثيرة أعلاءً لتوحيده سلماً وحرباً. وأمرنا أيضاً بغض الصوت فيما بيننا في التخاطب، فإن الجهر بأكثر من الحاجة تكلف يؤذي. والمراد بذلك كله التواضع). حيث يعتبر رفع الصوت في بعض المواضع شعيرة من شعائر الإسلام، كرفعه بالأذان والحج والإمامة وفي الصلاة وغيرها من الأمور التعبدية التي حث الإسلام عليها، بل حتى في ساحات الحروب لما في رفعه من زرع الرهبة في نفوس الأعداء، مما يجعله عاملاً مهماً في النصر.

Abstract

Of the many functions that are performed by the drilling fluid, the most important is to transport cuttings from the bit up the annulus to the surface. Various drilling fluid have been widely used in the oil industry to improve lifting capacity. In this study, three mud type have been used which they are, oil base mud, X-anthan polymer and a mixture of CMC and bentonite ,by using Carrying Capacity Index calculation (CCI) , the Xanthan gave good values of CCI than other studied drilling fluid. By using Sifferman chart and field data from well in south of Iraq and API equation to find cutting concentration in the annulus, The results showed that the used of thick mud increase the lifting capacity and decrease volumetric drill cuttings in the annulus but the using thin mud lead to decrease lifting capacity and increase volumetric drill cuttings in the annulus .The results show that the mud viscosity and flow rate have important role in hole cleaning. Also, the effect of annulus velocity and flow pattern on cutting transport ratio is studied by using field data. The effect of cutting size and OD of drill pipe is also studied. Cutting size is one of the parameters that influence the hole cleaning; large size cutting makes the hole cleaning more difficult. The reducing of annular size of hole by increasing the OD of drill pipe lead to increasing the annular velocity.

Abstract

Background and objectives: This study was designed to evaluate the clinical status of implants placed immediately in lifted maxillary sinus using Resorbable Tissue Replacement (R.T.R.) cone bone substitutes.Methods: Twenty implants were placed in twenty patients in the period between Jan. 2006 and Sept. 2010. Lateral approach, open window method for sinus lift with placement of Resorbable Tissue Replacement Cone bone substitutes were carried out. A 4-6 mm of the bone level was required in the alveolar ridge for primary stability, with sufficient inter-arch space for the prosthesis. All implants were placed in upper molar region simultaneously with sinus lift procedure in conjunction with Tissue Replacement Cone bone substitutes. The implant survival was defined when the prosthesis had been delivered and followed for two years without infection, pain, and mobility after loading.Results: Twenty patients, 13 males and 7 females, with an average age of 41 years old were participated in this study. A total of twenty implants were followed up for two years. Eighteen patients with eighteen implants (90.0%) showed no signs of sinusitis or other complications and the peri-implant health judged to be good with a peri-implant sulcus depth of 2-3mm. Two implants (10%) showed mobility before loading.Conclusion: A good survival rate was observed in implants placed immediately in lifted maxillary sinus using Resorbable Tissue Replacement (R.T.R.) cone bone substitutes.
