Experiments were designed to test the hypothesis that LHRH receptors in the preoptic area (POA) are of physiological importance for maintaining estrous cyclicity in the rat. Bilateral cannulae were implanted just dorsal to the POA. Estrous cycles were monitored daily by vaginal smears. Antide, a long-acting LHRH antagonist, was infused bilaterally (2.5 micrograms/side) in the POA or the hypotha...

BACKGROUND Delayed motherhood is a common phenomenon in the developed world, where the age at first delivery is around 30 years. In Chile the National Institute of Statistics established that this age has remained around 23 years for more than two decades. Motherhood postponement may be modulated by socioeconomic status. AIM To determine whether the age at first delivery is higher in a privat...

Numerous studies have been made of Recent Red Sea sediments concerning their paleontology, mineralogy, or geochemistry. In addition, over 50 reports have been published on the sedimentary environment of the hot brine area (21°N) in the central axial valley (see Degens and Ross, 1969, and contained references; Backer and Schoell, 1972). These studies generally indicate considerable climatic fluc...

Orobanche crenata is a holoparasitic plant that is potentially devastating to crop yield of legume species. Soil temperature and humidity are known to affect seed germination, however, the extent of their influence on germination and radicle growth of those of O. crenata is largely unknown. In this work, we studied the effects of temperature, water potential (Ψt) and the type of water stress (m...

The purpose of this study was to compare three different intervals for a between sets rest period during a common isokinetic knee extension strength-testing protocol of twenty older Brazilian men (66.30 ± 3.92 yrs). The volunteers underwent unilateral knee extension (Biodex System 3) testing to determine their individual isokinetic peak torque at 60, 90, and 120° ·s-1. The contraction speeds an...

development of remote sensing applications has led to their use in a wide range environmental studies. One these aspects is urban studies and especially land surface temperature. In this study, the changes temperature Khorramabad city Iran were investigated causes investigated. For purpose, Landsat satellite images processed four periods 2000, 2007, 2014 2021 recovered using single-channel algo...

This document is intended for people who want to “be aware” of some of the mechanisms underlying the JPEG2000 image compression standard [2]. While writing this tutorial my objective was to give to the reader the feeling of what goes on when compressing images with JPEG2000 . Hence, this tutorial should be regarded as introductory material which requires further reading to reach a deeper unders...

In this paper, we investigate the error resilience properties of JPEG2000. Through a careful analysis of the structure of JPEG2000 codestreams, we identify the dependencies among coding passes of a codeblock. In our analysis, we consider the effects of mode variations provided by the standard for low-memory, low-complexity implementations. The proposed methods are derived using the existing dep...

This manual is only partially complete and is a work in progress. A completed manual will be available by January 1,2000. Cluster and TreeView are Y2K Compliant because they are oblivious of date and time.

Abstract This article examines the spatial spillover effects of transport infrastructure in regions Vietnam. We apply Durbin model to estimate regional Vietnam’s economic growth from 2000-2019. The results show that positive evidence exists each period due connective nature at national level. At level, vary considerably over time among four macro-regions Vietnam: southern region always has a ef...
