ANOVA and Pearson correlation tests were used for the statistical analysis of the results.</p> <p>Results</p> <p>All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis.</p> <p>Conclusions</p> <p>Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.</p

Estudios sobre carotenoides y estabilidad oxidativa de aceites de semilla de calabaza de invierno y de soja

Winter squash seed and soybean oils were extracted with commercial hexane. Carotenoids and other pigments m the oils were studied using spectrophotometric and thin layer chromatographic analysis. Three types of pigments were identified: carotenoids. mainly lutein and β-carotene, chlorophyll and some unidentified pigments. Carotenoids content were 70, 60, 0 ppm in crude, refined and bleached winter squash seed oil, and 80, 65, 0 ppm in crude, refined and bleached soybean oil respectively. Stability was evaluated for crude, refined and bleached winter squash seed and soybean oils and an 1:1 admixture. Mixing winter squash seed oil with soybean oil increased the stability of soybean oil. Crude oil showed greater stability than refined and bleached oils.Se han extraído con hexano comercial aceites de semilla de calabaza y de soja. Usando análisis espectrofotométrico y cromatografía en capa fina se han estudiado en estos aceites tres tipos de pigmentos: carotenoides, principalmente luteína y β-caroteno, clorofilas y otros no identificados. Los contenidos en carotenoides fueron 70, 60, 0 ppm en aceite de semilla de calabaza de invierno crudo, refinado y decolorado, y 80, 65, 0 ppm en aceite de soja crudo, refinado y decolorado respectivamente.

A General Approach Students’ Attitude towards to Virtual Reality Technology in Distance Education Environment

E-learning has become a prominent and effective role in recent years. The factor of place and time became ineffective in the educational process. So that anyone can learn anywhere in the world. The educational services that benefit the learner during the educational process as well as the factors of assistance are important elements that help in the success of the educational process in the environment of e-learning. The more these services, the greater the benefit from e-learning. But its way of reviewing electronic content is still ineffective. Therefore it was necessary to create a suitable environment for the learner is similar to the real reality. Through which the learner feels the integration and concentration in the academic content as if it were realistic. So, the trend was to take advantage of the virtual reality technology that have become effective in all fields. The use of this technology will help the learner gain mo re realism and make full use of the electronic content. This study reviews the effect of the use of virtual reality technology in the review of the learner\u27s electronic content, as well as the attitudes and opinions of the students of the Business Information Systems program at the Faculty of Commerce, Helwan University, Cairo, Egypt, about the use of this technology and to what extent will effect on change and effectiveness in the quality of educational process

Parallel Distributed Compensation-PID Controller Design for Maximum Power Point Tracking of Dynamic Loaded Photovoltaic System

Control issues come from the output voltage of PV installations and systems operating in a range of irradiance and temperature. By using a DC converter, such systems are able to maintain a constant output voltage despite fluctuations in the generated voltage and load. The design of a maximum power point tracking (MPPT) on DC converter controller is presented in this article for a system. Fractional Order-Proportional Integral Derivative (FO-PID) and Parallel Distributed Compensation-Proportional Integral Derivative (PDC-PID) controllers have been implemented to the system converter as a proposed control approach. Particle Swarm Optimization (PSO) is used as optimization technique for determining the optimal parameters of (FO-PID) and (PDC-PID) controllers for tracking the output voltage from trained Adaptive Neuro Fuzzy Inference System (ANFIS) that is corresponding to maximum power generated from (PV) module. The PV system with the dynamic load is modeled and simulated by using the MATLAB/Simulink environment. The system performance is displayed in the form of a family of curves under different operating conditions

Analisis Perubahan Penjadwalan Dengan Metode Tracking Progres Pada Software Microsoft Project ( Studi Kasus Proyek Pembangunan Gedung Pendidikan Autis Kota Blitar Tahun 2013 )

Keterlambatan suatu item pekerjaan dalam sebuah proyek akan sangat mempengaruhi total durasi dari proyek tersebut, selama ini metode yang sering digunakan untuk me-monitor progress pekerjaan suatu proyek adalah metode kurva S dari persentasebobot biaya proyek yang mana hanya mengamati biaya yang sudah terlaksana dalam proyek tetapi tidak dapat digunakan untuk mengamati pengaruh keterlambatan suatu item pekerjaan terhadap total durasi dalam suatu proyek. Salah satu metode untuk me-monitor pengaruh keterlambatan terhadap total durasi proyek adalah dengan metode tracking progress sdalam software Microsoft Project. Tujuan dari penelitian ini adalah untuk mengetahui keterlambatan suatu aktivitas dalam proyek serta pengaruhnya terhadap total durasi dari proyek tersebut menggunakan tracking terhadap jadwal yang telah diberikan oleh pihak kontraktor. Pada penelitian ini dilakukan penjadwalan dengan MS project yang durasi pada setiap item pekerjaan berdasarkan dari jadwal rencana dan jadwal setelah addendum dari proyek tersebut, pada penjadwalan MS Project akan terlihat mana saja item pekerjaan yang tergolong kritis dan non-kritis. Sementara untuk me-monitor progress mingguan menggunakan fasilitas dari MS Project berupa tracking yang mana untuk memasukan progress tiap mingguan tetap menggunakan persen dari setiap item pekerjaanya. Hasil dari tracking tersebut akan memperlihatkan pertambahan total durasi dari proyek tersebut, jika suatu item pekerjaan dalam proyek tersebut mengalami keterlambatan maka total durasi dari proyek tersebut akan ikut bertambah. Sebaliknya, apabila item pekerjaan dalam proyek tersebut mengalami percepatan maka total durasi dari proyek tersebut akan berkurang. Hasil dari perbandingan jadwal yang di lakukan pada penilitian kali ini,adalah: untuk total dari durasi proyek tidak terdapat perbedaan hasil waktu dikarenakan mengguanakan data dari laporan mingguan yang sama yaitu selama 36 minggu untuk mencapai 100%, akan tetapi terdapat perbedaan hasil bobot pekerjaan ( % Complete ) tiap-tiap minggunya seperti deviasi keterlambatan terbesar pada kurva S terjadi pada minggu ke-17 dengan deviasi sebesar -48,3676%, sementara pada tracking hasil deviasi keterlambatan terjadi pada minggu ke-18 dengan deviasi sebesar 46,3391%
