One of the latest innovations in the technology of e-learning is the use of social networks (SN) for the creation and distribution of educational content and organization of communication of teachers and students. Orientation of the younger generation of students in the regular use of the SN in their daily, academic and professional life casts doubt on the prospects of the development of tradit...
The interaction in the system of SnO2 and h-MoO3 prepared by their joint mechanical activation in a roller-ring vibratory mill was investigated. A series of catalysts was prepared with SnO2: h-MoO3 molar ratio 1:1; 1:2.3; 2.3:1 and 5.7:1. The catalysts were characterized by various techniques including X-ray phase, X-ray diffraction (XRD) and synchron...
سنتز نانو ساختارهای پلاتین-قلع با استفاده از کمپلکس آلی – فلزی پلاتین و قلع در مرز مشترک تولوئن - آب
آلیاژ شدن فلزات غیر نجیب با پلاتین یک روش محبوب برای تولید کاتالیزورهای پلاتینی است که همراه با کاهش مصرف و افزایش فعالیت پلاتین است. این پژوهش، یک روش ساده و موثر جهت تهیه ی لایه ی نازک نانوذرات pt/sn، pt3/sn/go و pd/sn بر اساس کاهش کمپلکس ptcl2(cod)]]، pdcl2(cod)]] و ترکیب snme4 در سطح مشترک تولوئن-آب و در غیاب پایدار کننده ارائه می دهد. استفاده از پیش ماده ی آلی-فلزی که قادر به تخریب به صورت...
As only about 20% of sentinel node (SN) positive melanoma patients have additional non-SN lymph node involvement in the Completion Lymph Node Dissection (CLND) specimen, we tried to identify a SN positive patient group, which can be spared CLND. Micro anatomic analyses of metastatic SNs were performed to identify patient/tumor and/or SN factors predicting additional non-SN positivity as well as...
Dopaminergic networks modulate neural processing across a spectrum of function from perception to learning to action. Multiple organizational schemes based on anatomy and function have been proposed for dopaminergic nuclei in the midbrain. One schema originating in rodent models delineated ventral tegmental area (VTA), implicated in complex behaviors like addiction, from more lateral substantia...
We present optical and infrared observations of the unusual Type Ia supernova (SN) 2004eo. The light curves and spectra closely resemble those of the prototypical SN 1992A, and the luminosity at maximum (MB = −19.08) is close to the average for a SN Ia. However, the ejected Ni mass derived by modelling the bolometric light curve (about 0.45 M⊙) lies near the lower limit of the Ni mass distribut...
Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn-40 Pd suitable for potential application in direct ethanol fuel cells were synthesized using novel two-step electrodeposition method. First, Sn was electrodeposited various forms dendrites, from spear-like and needle-like to individual fern-like dendrites network intertwined by varying the cathodic then performing at current dens...
BACKGROUND Axillary lymph node status is one of the most important prognostic factors for breast cancer. The aim of this study was to determine predictive factors for metastasis to sentinel node (SN) in primary invasive breast cancer. METHOD This is a study of 3979 patients with primary breast cancer during 2008-2013 in Malmö and Lund scheduled for surgery and included in the information retr...
Irinotecan (CPT-11) is an analogue of 20(S)-camptothecin with promising activity against several tumor types. In patients, CPT-11 is metabolized to 7-ethyl-10-hydroxycamptothecin (SN-38) and to the beta-glucuronide of SN-38. Recently, we identified an additional metabolite of CPT-11, 7-ethyl-10-[4-N-(5-aminopentanoic acid)-1-piperidino] carbonyloxycamptothecin (APC; L. P. Rivory et al. , Cancer...
The electrodeposition of tin, bismuth, and tin-bismuth alloys from SnII and BiIII chlorometalate salts in the choline chloride/ethylene glycol (1:2 molar ratio) deep eutectic solvent was studied on glassy carbon and gold by cyclic voltammetry, rotating disc voltammetry, and chronoamperometry. The SnII-containing electrolyte showed one voltammetric redox process corresponding to SnII/Sn0. The di...
