The successful pursuit of the objective of low inflation by central banks in recent decades has also delivered low variability of both inflation and output. At the same time, numerous financial and other "imbalances" (defined here as significant and sustained deviations from historical norms) have emerged. Should these imbalances revert to the mean, there could be significant effects on output ...
In this study, waste concrete fine aggregates and cement are applied to sludge solidification resource recycling. The unconfined compressive strength (UCS) test is performed investigate the variation in stress–strain properties of solidified with content particle size aggregate, content, curing time. results show that incorporating can improve UCS cement-solidified sludge, which achieve optimum...
Species distribution models are widely used for stream bioassessment, estimating changes in habitat suitability and identifying conservation priorities. We tested the accuracy of three modelling strategies (single species ensemble, multi-species response and community classification models) to predict fish assemblages at reference stream segments in coastal subtropical Australia. We aimed to ev...
The experiment was conducted under a controlled environment to study the effects of different temperature regimes (15/10°C,20/15°C, and 25/20°C day/night) and sowing depths (0, 2, 4, and 6 cm) on the seedling emergence and early growth (height gain) of wheat (cv. Marvdasht) and wild barley (Hordeum spontaneum).The cumulative emergence and plant height gain over time were modeled with the use of...
The kinetics of synaptogenesis in the primary visual cortex (Brodmann's area 17) were analyzed by electron microscopy in 33 rhesus monkeys, ranging in age from the 50th embryonic day (E50) to 20 years. A series of overlapping electron micrographs (vertical probes) were examined at each age on sections of the upper bank of the calcarine fissure. Synaptic contacts were first observed in the E50 s...
BACKGROUND Cardiac sympathovagal balance is altered after resistance exercise. However, the impact of the characteristics of resistance training in this response remains unclear. OBJECTIVE Analyze the acute effect of resistance exercise intensity for trunk and upper limbs in cardiac autonomic modulation after exercise. METHODS Fifteen young men performed three experimental sessions in rando...
چکیده پویایی هر علمی در گرو نقد منصفانة آثار منتشرشده در آن زمینه است. بی تردید نگارش و پدیدآوردن یک اثر جدید در هر زمینه به بررسی و ارزیابی آثار منتشرشدة قبل از آن و بررسی کاستی ها و نقاط قوت آن ها بستگی بسیار دارد. این ارزیابی ها منجر به آن می شود تا تجدید چاپ و انتشار کتاب های جدید با کاستی کم تر و نوآوری بیش تری انجام پذیرد. یکی از نهادهای رسمی کشور که بررسی کتاب ها و متون آموزشی و کمک آموز...
Abstract This research was conducted to improve the engine performance with ethanol and gasoline mixture, because from fuel mixture high concentrate causes value of flash point heat evaporation fuels becomes higher. To overcome these, air that entrance in combustion chamber heated up 26°C, 30°C, 40°C 50°C, used are E0, E30 E50 on 2000 8000 rotation. The result shows E0 highest torque 30°C a 8,9...
Several papers have documented a regime switch in US monetary policy from ‘passive’ and destabilizing in the pre-1979 period to ‘active’ and stabilizing afterwards. These studies typically work with DSGE models with rational expectations. This paper relaxes the assumption of rational expectations and allows for learning instead. Economic agents form expectations from simple models and update th...
