Robustness assessment of Muscat coastal highway network (CHN) under multi-hazard scenarios focusing on traffic stability and adaptation measures.

This study critically examines the reliability and resilience of the Muscat coastal highway network (CHN) under the compounded effects of earthquakes and floods, representing interacting multi-hazard scenarios. The analysis utilized fragility functions for both earthquake-induced and flood-induced landslides, integrating these with traffic data for selected highway links to estimate bridge damage and assess CHN functionality in post-hazard conditions. Economic sensitivity analysis revealed a significant increase in costs due to flood-induced landslides, emphasizing the impact of dominant intensity measures on network costs and traffic flow.

Development of correlations between various engineering rockmass classification systems using railway tunnel data in Garhwal Himalaya, India.

Engineering rockmass classifications are an integral part of design, support and excavation procedures of tunnels, mines, and other underground structures. These classifications are directly linked to ground reaction and support requirements. Various classification systems are in practice and are still evolving.

leaf traits in degraded, restored, and natural mangrove ecosystems of Guyana.

Mangrove leaves have unique features that enable them to cope with shifting environmental conditions while preserving their general functionality and efficiency. We examined the morphological characteristics and chlorophyll content (spectroscopically) of 600 mature leaves selected from 30 trees located in one degraded, one restored, and one natural mangrove ecosystem along Guyana's coastline. Systematic sampling was carried out using the closest individual sampling method in the wet and dry seasons.

Chemical Composition, Antioxidant, Anti-Bacterial, and Anti-Cancer Activities of Essential Oils Extracted from Risso Peel Waste Remains after Commercial Use.

Citrus plants are widely utilized for edible purposes and medicinal utility throughout the world. However, because of the higher abundance of the antimicrobial compound D-Limonene, the peel waste cannot be disposed of by biogas production. Therefore, after the extraction of D-Limonene from the peel wastes, it can be easily disposed of.

Analysis of the chemical composition of root essential oil from Indian sarsaparilla () and its application as an ecofriendly insecticide and pharmacological agent.

The Indian sarsaparilla () is a commonly used plant in Indian traditional medicine of Ayurveda for the preparation of various non-alcoholic beverages. However, limited studies are available on the essential oil of roots (HRO); therefore, the study evaluated the antioxidant, anti-inflammatory and antidiabetic activities of root essential oil as well as insecticide potential against the common pests of stored food materials (, and ). The repellant efficacy of HRO was found to be high against (8.

Comparative evaluation of cardioprotective activity of and juice against isoprenaline-induced cardiotoxicity in rats.

Objectives: Comparative evaluation of cardioprotective activity of and juice against isoprenaline induced cardiotoxicity in rats.

Methods: Rats (125-150 g) were orally administered (GA) and (FA) apple juice (3 mL/day, per oral) for 13 days. Myocardial injury was inducted on 14th and 15th day by the administration of Isoprenaline (85 mg/kg/day, subcutaneous).

A review on diabetic foot challenges in Guyanese perspective.

Background: Diabetes mellitus signifies a major public health threat worldwide. Type 2 diabetes has been reported as the fourth leading cause of death and has affected 15.5% of the adult population in Guyana, South America.

A study to identify bacteriological profile and other risk factors among diabetic and non-diabetic foot ulcer patients in a Guyanese hospital setting.

Diabetic foot infection is a global epidemic and a major public health concern. Development of microbial resistance to many antimicrobial agents in foot ulcer leads to serious complications. Therefore, the study aims to identify the microbiological profile and the potential risk factors among diabetic and non-diabetic foot ulcer patients.

Tropical Rainforest and Human-Modified Landscapes Support Unique Butterfly Communities That Differ in Abundance and Diversity.

Tropical forests account for at least 50% of documented diversity, but anthropogenic activities are converting forests to agriculture and urban areas at an alarming rate, with potentially strong effects on insect abundance and diversity. However, the questions remain whether insect populations are uniformly affected by land conversion and if insect conservation can occur in agricultural margins and urban gardens. We compare butterfly populations in tropical secondary forests to those found in sugarcane and urban areas in coastal Guyana and evaluate the potential for particular butterfly communities to inhabit human-modified landscapes.

Molecular and phytochemical analysis of wild type and olive cultivars grown under Saudi Arabian environment.

This study aimed to assess genetic variability at molecular and phytochemical levels among the four most commonly grown olive cultivars and the wild-type olive of Saudi Arabia. Sixty-six and 80 amplicons were generated from 9 random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) primers, each, producing an average of 95.9 and 86.

Standardization of Unani Antidiabetic Tablet - Qurse Tabasheer.

Background: Quality control of Unani polyherbal formulations is the need of the day for better acceptance of Unani medicine. Qurse Tabasheer (QT) is a Unani polyherbal formulation containing six ingredients, Tabasheer (Siliceous concretions) (Bambosa arundinaceae Retz.), Gule Surkh (Rosa damascena Mill.

Prevalence of erectile dysfunction in male stroke patients, and associated co-morbidities and risk factors.

Background: Sexual problems have been a common finding in chronically ill and physically disabled patients such as those with cerebrovascular accidents. Previous studies have supported the association between stroke and erectile dysfunction (ED).

Objectives: The aim of this study was to investigate the prevalence of ED and its severity in male stroke patients in Qatar and to assess the co-morbidities and risk factors associated with ED.

Prevalence of erectile dysfunction among hypertensive and nonhypertensive Qatari men.

Objectives: The aim of this study was to investigate the prevalence of erectile dysfunction, its severity, and other sexual function domains in hypertensive and normotensive Qatari's men and to estimate the association between hypertension and predictors of erectile dysfunction.

Material And Methods: A matched case-control study was conducted at the primary health care clinics during a period from May to October 2006. Four hundred twenty-five hypertensive patients and 425 age-matched normotensive attendants of primary health care clinics, aged 30-75 years, were approached for the study.

Erectile dysfunction among hypertensive men in a rapidly developing country.

Background: Previous studies have supported the association between hypertension and erectile dysfunction (ED). In addition, a significant correlation between hypertension in men and ED has been well established.

Objectives: The aim of this study was to investigate the prevalence of ED, its severity and other sexual function domains in hypertensive patients in Qatar.
