引用

Acta mathematica Scientia 2014年第4期34卷 1301-1330页

作者：艾尼.吾甫尔艾合买提.卡斯木 College of mathematics and System Sciences Xinjiang University

By studying the spectral properties of the underlying operator corresponding to the m/G/1 queueing model with optional second service we obtain that the time-dependent solution of the model strongly converges to its steady-state solution. We also show that the time-dependent queueing size at the departure point converges to the corresponding steady-state queueing size at the departure point.

引用

Circuits and Systems 2013年第1期4卷 83-88页

作者： kasim Karam Abdalla Department of Electrical Engineering Engineering Colloge University of Babylon Hilla Iraq

A new universal multiple input multiple output (mImO) type current-mode biquad employing two dual output current conveyors (DOCCII), one multiple output current controlled current amplifier (mOCCCA) and four passive grounded elements is proposed which can realize all the five basic filtering functions namely, low-pass (LP), high-pass (HP), band-pass (BP), band-stop (BR) and all-pass (AP) in current mode from the same configuration. The centre frequency can be set by the passive elements of the circuit and the quality factor Q0 is electronically tunable through bias currents of the mOCCCA. Therefore, the biquad filter has independent tenability for the and Q0. The active and passive sensitivities of Q0 and are low. The workability of the new configuration has been demonstrated by PSPICE simulation results based upon a CmOS CCII in0.35μm technology.

Sustainability Impact on Construction management in Developing Countries： Iraq as a Case Study

引用

Journal of Civil Engineering and Architecture 2012年第4期6卷 403-414页

作者： Basil kasim mohamed School of Civil and Construction Engineering Oregon State University

Sustainable development contributes to the economic and social advancement of construction projects. Ignoring sustainability during the cost estimating process associated with evaluation phase develops many problems of conventional decision methodology used in construction industry in the most of developing countries. This research focuses on sustainability which is the key factor in all decision making in design and construction processes. Therefore, Iraqi construction industry should respond to sustainability as a leading indicator of its infrastructure rebuilding. The construction management and sustainability could help to manage the rebuilding of the destroyed public infrastructure during the disaster wars periods passed thru thirty years ago and also to modernize of private buildings and plants. Field study has been carried out by adopting personal interviews and questionnaires conducted with experts, experienced consultants and designers working in many design organizations. The data collected has been analyzed and the results obtained show a clear weakness in the field of sustainability understanding, practicing and implementation. moreover, the design work in Iraq is suffering from a lack of scientific techniques and a lack in experience in the domain of sustainability field. This will take an integrated approach to study the impact of sustainability on construction management which encompasses both public and private sector perspectives for building and engineering construction, and the roles played by all the participants in the construction team （owners, contractors, design professionals, and other supporting professionals）.

引用

materials Sciences and Applications 2013年第5期4卷 287-292页

作者： kasim Uthman Isah Department of Physics Federal University of Technology Minna Nigeria

Cadmium Zinc Sulfide, Cd1-xZnxS thin films were deposited by chemical bath deposition technique at bath temperature of 75°C. The morphology of the films was analyzed by scanning electron microscope, the optical constants of the films were estimated from the transmission and reflection spectra of the films in the wavelength range of 300 - 900 nm. The films had a transmittance between 75% and 85% and optical band gap in the range 2.8 - 3.4 eV. The dependence of the refractive index of the films on the wavelength was investigated using the single oscillator model, from which the dispersion parameters were determined. The high frequency dielectric constant εL and the ratio of the carrier concentration to the effective mass N/m* were estimated based on the Spitzer and Fan model. Both εL and N/m* show a decrease in value with increase in Zinc content.

Pulmonary hypertension(PH) is a life-threatening disease characterized by pulmonary vascular remodeling, in which hyperproliferation of pulmonary artery smooth muscle cells(PASmCs)plays an important role. The cysteine 674(C674) in the sarcoplasmic/endoplasmic reticulum Ca^(2+)ATPase 2(SERCA2) is the critical redox regulatory cysteine to regulate SERCA2 activity. Heterozygous SERCA2 C674 S knock-in mice(SKI), where one copy of C674 was substituted by serine to represent partial C674 oxidative inactivation, developed significant pulmonary vascular remodeling resembling human PH, and their right ventricular systolic pressure modestly increased with age. In PASmCs, substitution of C674 activated inositol requiring enzyme 1 alpha(IRE1 a) and spliced X-box binding protein 1(XBP1 s) pathway, accelerated cell cycle and cell proliferation, which reversed by IRE1 a/XBP1 s pathway inhibitor 4μ8 C. In addition, suppressing the IRE1 a/XBP1 s pathway prevented pulmonary vascular remodeling caused by substitution of C674. Similar to SERCA2 a, SERCA2 b is also important to restrict the proliferation of PASmCs. Our study articulates the causal effect of C674 oxidative inactivation on the development of pulmonary vascular remodeling and PH, emphasizing the importance of C674 in restricting PASmC proliferation to maintain pulmonary vascular homeostasis. moreover, the IRE1 a/XBP1 s pathway and SERCA2 might be potential targets for PH therapy.

Q-switched ytterbium doped fiber laser using multi-walled carbon nanotubes saturable absorber

引用

Chinese Optics Letters 2014年第3期12卷 41-44页

作者： N.kasim A.H.H.Al-masoodi F.Ahmad Y.munajat H.Ahmad S.W.Harun Advanced Photonics Science Institute Faculty of ScienceUniversity Technology Malaysia Photonics Research Centre University of Malaya Department of Electrical Engineering Faculty of EngineeringUniversity of Malaya

A Q-switched ytterbium-doped fiber laser （YDFL） is proposed and demonstrated using a newly developed multi-walled carbon nanotubes polyethylene oxide （mWCNTs-PEO） film as a passive saturable absorber （SA）. The saturable absorber is prepared by mixing the mWCNTs homogeneous solution into a dilute PEO polymer solution before it is left to dry at room temperature to produce thin film. Then the film is sandwiched between two FC/PC fiber connectors and integrated into the laser cavity for Q-switching pulse generation. The laser generates a stable pulse operating at wavelength of 1060.2 nm with a threshold pump power of 53.43 mW. The YDFL generates a stable pulse train with repetition rates ranging from 7.92 to 24.27 kHz by varying 980-nm pump power from 53.42 to 65.72 mW. At 59.55-mW pump power, the lowest pulse width and the highest pulse energy are obtained at 12.18 μs and 143.5 n J, respectively.

作者： Karam Kenawy Abdin K. kasim momen m. Almamoun Department of Neurosurgery Sohag University Sohag Egypt

Objective: Tuberculum sellae meningiomas constitute about 5% - 10% of intracranial meningiomas. They are difficult to treat, owing to their close association with the optic nerves, chiasma, and major cerebral arteries. This retrospective study aims to report on the clinical outcome after transcranial approach for treatment of tuberculem sellae meningiomas at our hospital. Patients and methods: We reviewed patients with tuberculem sellae meningiomas and underwent transcranial surgical approaches for their lesions at Sohag university hospitals over a 4 years period starting from January 2018. The patients’ clinical and radiological data, operative details, degrees of tumor removal, outcomes and complications were reported. Results: There were 17 patients with tuberculem sellae meningiomas with a mean age of 46.3 years. Female patients constituted 70% of cases. Pterional approach was used in 59% of cases and unilateral subfrontal approach was used in 41% of cases. Gross total tumor removal was achieved in 82% of cases. Visual acuity improved in 47%, remained unchanged in 41%, and worsened in 5.9% of patients. Transient post-operative diabetes inspidus and post-operative haematoma in tumor bed each occurred in 5.9% of patients. Conclusion: Transcranial removal of tuberculum sellae meningioma is still considered the standard approach, with high rate of gross total resection and better visual outcome and low mortality and morbidity.
