Next, we discuss the point-based and interval-based versions of time. These were studied in Johan van Benthem’s book The logic of time and in several papers appearing around the same time: Vilain [1982], and Allen [1983], developed an interval algebra; Moszkowski and Manna [1983], as well as Schwartz, Melliar-Smith and Vogt [1983], advocated interval-based reasoning for hardware. The prohibitiv...

introduction: the aim of the present study was to evaluate the expression of fibronectin (fn) and tenascin (tn) after direct pulp capping (dpc) in dogs’ teeth with either mineral trioxide aggregate (mta), propolis or platelet-rich plasma (prp), by means of immunohistochemistry. methods and materials: a total of 48 sound molars and premolars with mature apices from four dogs, were included. the ...

Kuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X) and g(Y ), E [f(X)g(Y )] = E [f(X)] E [g(Y )], where E [·] denotes interval-valued expectation and denotes interval multiplication. We present properties of Kuznetsov independence for several variables, and connect it with other concepts of independence in the literature; in particular we show that st...

目的：日帰りで行う待機的虫垂切除術の安全性と有用性について，入院手術と比較検討した．方法：2017年1月から2021年12月までの5年間に2施設において膿瘍ドレナージ例と小児を除く待機的虫垂切除術を行った連続した256例を対象とした．これら2施設のうち一方は日帰り手術を基本としており，この施設で治療を行った症例（以下，日帰り群と略記）の治療成績や治療費用を，他方の従来の入院手術を基本とする施設での治療症例（以下，従来群と略記）を対照として後向きに比較検討した．結果：日帰り群166例，従来群90例で，手術時間中央値は日帰り群35分，従来群64分（P<0.001）と有意差を認めた．日帰り群は全例日帰りで帰宅できた．合併症率は有意差なく（P=0.15），重篤な合併症は認めなかった．手術費用は，日帰り手術が約29万円，入院手術が約46万円であった．結語：日帰りで行う待機的虫垂切除術は，適正な...

Background & aim: Recently, the use of mifepristone followed by misoprostol after 36-48 h has been demonstrated to be an effective and safe method for the second trimester medical abortion. However, this regimen entails long total abortion time, and consequently increases the financial burden and anxiety in the patients. We hypothesize that one day interval would be also effective and can be us...

in this research, 272977 test day records collected from 659 herds during years 2001 to 2011 by the iranian animal breeding center were used. in the first section the ability of different models to predict daily milk yield from alternative milk recording was tested. the result showed that a complex model including noon milking time plus the effect of lactation curve of ali and schaeffer functio...

BACKGROUND: Nutrients play a very important role in chemical, biochemical, physiological, metabolic, geochemical, biogeochemical, and enzymatic processes. Innovations for saving water in irrigated agriculture and thereby improving water use efficiency are of paramount importance in water-scarce regions. Conventional deficit irrigation is one approach that can reduce water use w...
