Assessing the implementation of environmental management plans (EMPs) in construction projects is crucial for meeting sustainability goals and reducing potential adverse impacts. By using performance indicators (PIs), stakeholders can objectively measure EMP implementation, identifying areas success that may require improvement. Therefore, this study aims to examine PIs assessing water supply projects, Saudi Arabia as a case study. Data from semi-structured interviews systematic literature...

Providing an accurate spatiotemporal distribution of rainfall and filling data gaps are pivotal for effective water resource management. This study focuses on the Asir region in southwest Saudi Arabia. Given limited accuracy satellite this arid/mountain-dominated area, geospatial interpolation has emerged as a viable alternative approach terrestrial records gaps. Furthermore, irregularity rain gauge yearly spatial variation hinder creation coherent pattern. To address this, Centered Root...

Different extracts of both fresh and dry leaves Aloe eru A. Berger, vera L. Webb & Berth arborescens Mill. were screened for their antifungal activity against Aspergillus niger, Cladosporium herbarum Fusarium moniliforme. The toxicity the isolated pure components evaluated on tested fungi. A comparative chromatographic study was performed to differentiate between natural existing in various fractions species specific spray reagents used detection anthraquinones components.

The availability of data is an important aspect in frequency analysis. This paper explores the joint use lim- ited from ground rainfall stations and TRMM to develop Intensity Duration Frequency (IDF) curves, where very limited station records are available. Homogeneity means variances first checked for both types data. study zone assumed be belonging same region using Wiltshire test. An Index Flood procedure adopted generate theoretical regional distribution equation. Rainfall depths at...

This research aims to examine the performance indicators that are crucial for assessing implementation of environmental management plans (EMPs) in water projects. To achieve this aim, a questionnaire survey, integrating systematic literature review (SLR), was used identify initial indicators. Subsequently, ten interviews with professionals were carried out uncover additional not identified by SLR. Following survey design and pilot study data collection resulted 112 valid responses from...

An experimental evaluation of the effect channel depth ratio and absorber plate configuration on performance a baffled counter flow double-pass solar air heater (BCDSAH) is main objective current work. The BCDSAH was constructed so as to permit adjustments (CDR) 2, 3 4. During experimentation, lower kept at 50 mm while upper adjusted 100 mm, 150 200 yielding various ratios. assessments were conducted for three configurations plate: (i) flat plate, (ii) (iii) with phase change material (PCM)....

Abstract Background Sarcopenia is a common problem in hemodialysis (HD) patients, and it diagnosed by low muscle mass, strength and/or physical performance. Muscle ultrasound (US) non-invasive portable tool that might be used for assessment of mass. The aim the current study was to investigate concordance between US bioelectrical impedance analysis (BIA) diagnosis sarcopenia HD patients. Methods This cross-sectional included 41 according European Working Group on Older People (EWGSOP)....

Abstract The 13 C NMR data of six pairs 18α/18β‐glycyrrhetic acid derivatives are presented. It is shown that the configuration at C‐18 can easily be recognized by inspecting chemical shifts several characteristic carbons, e.g. C‐12, C‐13, and C‐28. these carbons originated change D/E ring junction proved to largely independent substitution C‐3 C‐20.

Abstract The mass spectra of ten dehydration and solvolysis products obtained from β‐amyrin glycyrrhetic acid were studied. With the exception those resulting ‘backbone’ rearrangement, they exhibited conventional fragmentation due to ring C chromophore, like parent alcohols. Only with a contracted A suffered loss an isopropyl radical. In latter type, special features by isopropylcyclopentene isopropylidene products. These differences enabled assignment probable structures for two unknown derivatives.

In this study, experimental and numerical investigations of the dense brine jets are conducted for disposal areas limited extent. First, a new model representing section sea floor with single port outfall is built to study different characteristics jets. Second, number experiments have been via Fluent CFD package compare results its corresponding physical observations measurements. Experimental made both terminal height rise discharged vertically from circular outlets into calm homogeneous...

Aus Ziziphus nummularia wurden neben den bereits beschriebenen Nummularinen-A, -B, -C, -D, -E und -F drei weitere Peptidalkaloide, Nummularin-G, -H -K isoliert deren Konstitution geklärt (1, 3 5). Die Nummularine-G besitzen 14 gliedrige Cyclopeptidringe. Als Besonderheit weist 1 einen zusätzlichen Ring in der Seitenkette auf. Nummularin-H (3) gehört zu 13 gliedrigen Cyclopeptidalkaloiden besitzt die eines N-Desmethyl-jubanins-A. Alkaloids from Rhamnaceae, XXVIII. and -K, New From addition to...

Objective. To study the photoplethysmographic (PPG) waveforms of different locations (ear and finger) during lower body negative pressure (LBNP) induced hypovolemia. Then, to determine whether PPG waveform can be used detect hypovolemia early stage LBNP.Approach. 36 healthy volunteers were recruited for progressive LBNP hypovolemia, with an endpoint -60 mmHg or development hypoperfusion symptoms, whichever comes first. Subjects tolerating entire protocol without symptoms designated as high...
