In this paper, we extend the recently introduced vertex-degree-based topological index, Sombor and call it general index. The index generalizes both forgotten We present bounds in terms of other important graph parameters for also explore Nordhaus–Gaddum-type result further relations between generalized indices: Randić sum-connectivity
Background & Objectives: Despite the extensive interest shown in depression occurring in stroke patients, little attention has been paid focus on depression of caregivers of stroke survivors particularly in Iran therefore this study was designed to assess the prevalence of depressive symptoms among caregivers of stroke survivors and to determine putative risk factors. Methods: This cross-sectio...
Drought is a climatic phenomenon that begins slowly and has a hidden nature. The duration of its occurrence and the resulting damage occur gradually in different sectors. Therefore, assessment and investigation of drought is very important in planning and implementation of actions to cope with drought. Droughts are divided into different types. One of the common methods of drought assessment is...
Introduction: This research aimed to analyze the effect of 12 weeks aerobic exercise training on some characteristics of immune system and general health of women with breast cancer. Methods: 40 female with breast cancer, undertaking chemotherapy, were classified in exercise group with mean age of 36/9±13/2 years, weight of 67/2±9/95 kilograms and body mass index of 21/9±2/9 kg/m2 and contro...
مقدار تبخیر و تعرق حقیقی مزرعه یونجه واقع در باجگاه بوسیله روش تعادل آبیاری در 9 کرت آزمایشی و دولیسمتر از نوع وزنی بمنظور تعیین آب مصرفی گیاه یونجه تعیین شد. در طول مدت آزمایش مقدار آب موجود در خاک بوسیله نمونه برداری وزنی از خاک و دستگاه نوترون متر تعیین و مقدار تشعشع رسیده از خورشید بزمین و ساعات آفتابی روز نیز اندازه گیری شد. مقدار تبخیر و تعرق پتانسیل بوسیله روشهای modified blaney-criddle ...
A class of realizable active media exists for which the refractive index cannot be defined as an analytic function in the upper half-plane of complex frequency. The conventional definition of the refractive index based on analyticity is modified such that it is valid for active media in general, and associated Fresnel equations are proved. In certain active media, the presence of a "backward" w...
This study, conducted between 2016–2021 on Southeast Asian mining companies, introduces the Modified Enterprise Risk Management (ERM) Index (MERMi) to measure implementation of ERM based COSO 2017 principles. The study found that is influenced by industry competition, company complexity, international diversification, and financial leverage. Meanwhile, size along with positively impact firm per...
