abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
This study investigates the evolution of temperatures at several locations in Pakistan. Data on annual and seasonal minimum (Tn) maximum (Tx) from 1950 to 2013 urban (16 stations), town (11 rural (nine stations) areas are analysed establish mean decadal rate change urban, town, temperatures. The homogeneity data was assessed using HOMER 2.6. To measure temporal intensity temperature, were split...
Objectives: The current study investigated the potential acceptability and effectiveness of Contextual Intervention adapted for Autism Spectrum Disorders (CI-ASD) in developing children’s participation and mothers’ parenting self efficacy. Contextual Intervention adapted for Autism Spectrum Disorders (CI-ASD) involving contextually reflective occupational therapy combines 3 elements: parent coac...
In-situ powder neutron diffraction studies have been performed during the heating treatment of a set of Nb3Sn wires obtained by the internal tin process. The different phases appearing during the process have been evidenced. A strong reorientation of the deformed copper and niobium metals induces an orientation on the Nb3Sn formed. Among the phases formed, the δ-CuSn phase is decomposed at 890K...
چکیده مجموعه حاضر با هدف معرفی و ارائه ی توصیفی برای اصطلاحات رایج در دانش معنی شناسی تهیه شده است. برای دستیابی به چنین هدفی سعی بر آن بود تا صرفاً به واژگان نقش مند در شاخه ی عمده ی معنی شناسی زبانی توجه شود. در حوزه معنی شناسی زبانی، به اصطلاحات در شاخه ای از این دانش، یعنی معنی شناسی نظری (theoretical semantics) و آنچه معنی شناسی کاربردی (applied semantics) نامیده ایم، اشاره شود. و هدف از ت...
Background: In this study, with the aim of modeling Leukemia in children using Phase-type distribution, three transitional phases including diagnosis, brain metastasis and testis/ovary metastasis, and one absorotion phase of recovery/death have been considered. The distribution was fitted and the probabilities of death or recovery were determined based on the independent variab...
Southern Oscillation Index (SOI) and Sea Surface Temperature (SST) patterns affect rainfall in many parts of the world. This study aimed to investigate the relationship between monthly and seasonal rainfall of Iran versus SOI and Pacific and Indian sea surface temperature. Monthly rainfall data, from 50 synoptic stations with at least 30 years of records up to the end of 2007, were used. Monthl...
conclusions the stress due to psychosomatic changes in the menstrual cycle is associated with premenstrual syndrome. measures of s-iga, rather than cortisol or subjective responses to stress, may be most closely associated with pms. background several studies have demonstrated the associations between premenstrual syndrome and perceived stress, and no studies quantifying stress based on biochem...
This paper shows a novel concept of using diffusion maps for dimensionality reduction when tracing problems in 3G radio networks. The main goal of the study is to identify abnormally behaving base station from a large set of data and find out reasons why the identified base stations behave differently. The paper describes an algorithm consisting of preprocessing, detection and analysis phases w...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
