Magne c resonance imaging (MRI) was applied to the study of fl ow processes in model and natural soil cores. Flow veloci es in soils are mostly too slow to be monitored directly by MRI fl ow velocity imaging. Therefore, we used for the fi rst me diethylenetriaminepentaacetate in the form Gd-DTPA2− as a tracer in spin echo mul slice imaging protocols with strong weigh ng of longitudinal relaxa o...

We present an experimental method to fill in the existing gap of characterization tools for the mechanical testing of fused silica and silica’s polymorphic phases in the microand nanoscales. The approach is based on a monolithic tensile tester, entirely made of fused silica for which the same femtosecond laser in not only used for the fabrication of the device, but also for its operation (loadi...

ABSTRACT This study aimed to estimate the prevalence of adherence social isolation and inves- tigate associated factors during Covid-19 pandemic among teachers in Minas Gerais, Brazil. is a cross-sectional carried out with sample 15,641 teachers. A digital form was applied for data collection. Descriptive analyses variables were conducted, which included isolation, sociodemographic characterist...

the entomopathogenic-fungus-life cycle is associated with the synthesis and secretion of a number of toxic metabolites, including extracellular enzymes and the low-molecular weight compound (toxin). the potential for a successful pathogen relies on the ability to overcome the various host-defence systems. interaction between the fungus, tolypocla-dium (deuteromycetes), its secondary metabolite,...

Background: To explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in Arak city, Arak province, Iran. Materials and Methods: One hundred and thirty four pa!ents with breast cancer were inves!gated. ABO blood groups were obtained from medical records. Mul!variate analyses were performed, including size of tumor, axilla...

The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

In this study, the effects of surface roughness differences vehicle coating materials (paint, paste, special applications, etc.) on aerodynamic drag coefficient were inves-tigated using finite element method. For this, forces and aerody-namic coefficients for speeds between 40-150 km/hours calculated a 1/20 scale designed by package program defining body parts front-rear window separately assig...

The in vivo localization of radiolabeled heterospecific antibody to carcinoembryonic antigen (CEA) was inves tigated in a human colonie tumor-hamster host model. With the paired-labeled antibody technique, a significant and specific accumulation of goat anti-CEA immunoglobulin G (IgG) was observed in small tumors (<5.0 g) l day after injection. The level of anti-CEA IgG in the tumor sub sequent...

The interaction between light and organometallic chromophores has been inves-tigated theoretically in a strive for fast optical filters. The main emphasis is ontwo-photon absorption and excited state absorption as illustrated in the Jablon-ski diagram. We stress the need for relativistic calculations and have developedmethods to address this issue. Furthermore, we present how qu...
