Metakaolins (MKs) prepared from low-grade kaolins located in the Alvarães (A) and Barqueiros (B) regions of Portugal were used as aluminosilicate source to compare their effect on compressive strength heavy metal adsorption geopolymers. Natural zeolite, an inexpensive, efficient adsorbent, was additive formulations enhance geopolymers’ capacities reduce MK utilization’s environmental footprint....

BACKGROUND Major depressive disorder (MDD) is a common mental disorder worldwide, but now there is a lack of clinically effective assessment and management of MDD. In this study, we used technetium-99 m ethylcysteinate dimer ([99mTc]ECD) SPECT/CT to characterize the regional cerebral blood flow (rCBF) status of MDD patients, and to explore an objective image assessment model of MDD which is non...

Ketamine has been reported to impair the capacity for learning and memory. This study examined whether these capacities were also altered in the offspring and investigated the role of the CREB signaling pathway in pregnant rats, subjected to ketamine-induced anesthesia. On the 14th day of gestation (P14), female rats were anesthetized for 3 h via intravenous ketamine injection (200 mg/Kg). Morr...

A hypothesis was tested that the in ovo injection of biological buffers may reinforce the buffering capacity of albumen, thereby withstanding the increase in albumen pH during storage and improving hatchability and chick quality in long-term stored eggs. Hatching eggs (n = 2,420) were randomly assigned to 11 treatment groups (4 replicates of 55 eggs each) and injected (d 1) with distilled water...

BACKGROUND Fluctuations in the national economy shape labour market opportunities and outcomes, which in turn may influence the accumulation of cognitive reserve. This study examines whether economic recessions experienced in early and mid-adulthood are associated with later-life cognitive function. METHOD Data came from 12,020 respondents in 11 countries participating in the Survey of Health...

Insulin degradation within isolated rat liver endosomes was studied in vitro with the aid of three 125I-insulin isomers specifically labelled at tyrosine (A14, B16 and B26). Chloroquine and 1,10-phenanthroline were used to minimize insulin proteolysis during endosome preparation, whereas the manipulation of endosomal processing of insulin in vitro by Co2+ ions (to activate) and 1,10-phenanthrol...

We have studied the time sequence degradation of native insulin by insulin protease from human fibroblast using multiple steps involving purification of the products by high performance liquid chromatography, determination of peak composition by amino acid sequence analysis, and confirmation of structure by mass spectrometry and thus elucidated the sites of cleavage of insulin by human insulin ...

The Italian contribution to the Socialist Economic Calculation Debate (SECD) cannot be limited important and fundamental works by Pareto Barone. In fact, if their contributions are still ambiguous we have wait for Mises’ paper in 1920 order get needed clarifications, during 1960s Bruno Leoni follows Austrian footsteps on topic, stimulating Italy a great debate. Leoni’s role is because of debate...

Biodiesel is widely accepted as a fuel that similar to diesel with various advantages. Biodiesel's low-temperature flow qualities are one of its characteristics limits use. The goal this study was see how volumetric blends palm biodiesel and diesel, affected the performance emissions fired vertical coil type, water tube, non IBR boiler. Various were prepared like PB25, PB50, PB75, PB100 test in...

The aim of this short communiqué is to adapt a result established by Bliman, related to the possible approximation of the solutions to real-parameter-dependent linear matrix inequalities (LMIs), to the special context of stability analysis of 2D discrete Roesser models. While Bliman considered the case of LMIs involving several real parameters, which is especially crucial for the analysis of li...
