Data-Driven Modelling And Application In Circular Economy: A European Water Efficiency Study
(2025-06)
Bronner, Mike
In 2007, the european union pledged to become a water-efficient community, a crucial step towards sustainable development, yet progress is constrained by the absence of relevant benchmarking and scientific insight. Addressing this gap, this thesis models and evaluates water use, public water sector, and economic water cycle efficiency across european countries, integrating mathematical and statistical methods, economic theories, and circular economy principles. Europe’s water resources face growing pressure from climate change, overexploitation, and pollution. Notwithstanding the importance of improving water efficiency in both demand and supply to strengthen water security, advancements are impeded by a lack of assessment tools and research-based guidance tailored to diverse conditions. Moreover, despite efforts to adopt circular economy practices, there is substantial untapped potential, particularly exemplified by germany. In response, the objectives of this thesis are to introduce frameworks for assessing water utilisation and sector efficiency across europe, equipping stakeholders with decision-support instruments and insights to guide performance optimisation and facilitate cross-border learning, and to pioneer a comprehensive resource circularity-based assessment approach to inform holistic water economy performance improvements
Moderating Role Of Supportive Work Environment On The Relationship Between Intellectual Capital And Firm Performance: A Case Of Construction Organizations In Uae
(2025-05)
Al Arbid, Adham Joudi
The uae's construction industry is crucial for economic and social development, but it faces challenges that hinder performance improvement. Intellectual capital plays a key role in addressing these issues and enhancing industry outcomes. The aim of this study is to examine the role of intellectual capital components in the performance of the construction industry in the uae. Moreover, this research also explores the moderating role of supportive work behavior on the relationship between intellectual capital components and the performance of the construction industry in a similar region. Primary data were collected through a structured questionnaire, and a valid sample of 408 respondents from the construction industry was finally analyzed using measurement model and structural model techniques through smart pls. All tests for measurement model assessment in terms of validity and reliability of the constructs have been applied. Furthermore, findings from the structural equation modeling approach suggest a significant and positive impact of human capital, structural capital, spiritual capital, and relational capital on the performance of the construction industry.
Embriogenesis Somatik Dan Penginokulatan In Vitro Tebu (Saccharum Officinarum) Dengan Kulat
(1997-06)
Ayob, Afizah
Three types of explants used in this experiment were spindle, . Apical meristem and subapical meristem. From the culturing process, the production of calli were identified as compact callus, soft callus and mucilagenous callus. The first two calli are embryogenic. From the comparison done, the spindle explant was capable in producing the embryogenic calli when cultured on the ms medium with the presence of 2,4-d (2,4- dichloro phenoxy acetic acid) and activated carbon. Explants on the ms medium + 3.0 mg/l 2,4-d and 2.5 gil activated carbon produced the largest quantity of calli. Somatic embryogenesis process was achieved through the culturing of embryogenic callus on the ms medium + 0.25 mg/i kinetin + 2.5 g/l activated carbon for the purpose of multiple shoots formation. Ms medium + 5.0 mg/l naa (ce-naphtalene acetic acid) and 2.5 gil activated carbon were used in roots induction. However, the additional of 7% of sucrose in this medium increased the quality of roots produced. The somatic embryogenesis process produced the complete somatic embryo which consists of scutellum, coleoptile, shoot meristem, col eorhiza and root meristem from the embryogenic callus. A complete plantlet was produced within 3 months of culturing. The presence of somaclonal variation were observed amongst plantlets which include these characteristic; colour and shape of the leaves, as well as the height of the plantlets.
Impact Of Human Resources Management Practices On Turnover Intention Among Hotel Employees In Amman, Jordan
(2024-03)
Mohd, Maqableh Omar Aref
This study determines the relationship between HRM practices and turnover intention among five-star hotels in the Jordanian capital, Amman. This study investigated also the mediating effect of job satisfaction on the connection between HRM practices and turnover intention in addition to the moderation impact of employee innovative behavior on the relationship among the HRM practices and employee turnover intention, in addition to the moderating influence of employee innovative behavior on the connection between job satisfaction and turnover intention.
The Correlation Study Between Cytokines Il-6, Tnf- Α And Other Biochemical Parameters With Adipokines Visfatin And Chemerin In End Stage Renal Disease Patients Undergoing Haemodialysis
(2024-02)
Mohammed Al Ani, Mohammed Riyadh
This study aimed to determine the levels of various parameters in patients with ESRD undergoing haemodialysis, to evaluate how dialysis affect these parameters during haemodialysis sessions and to correlate the levels adipokines, inflammatory markers and metabolic parameters in ESRD patients. The study measured serum cytokines (TNF-α, IL-6), serum adipokines (visfatin, chemerin) vitamin D, amylase, glucose, urea, serum lipid profile (cholesterol, HDL, TG), serum liver function test (ALT, AST, ALP, direct bilirubin, total bilirubin, total protein, albumin, LDH) and serum renal function test (uric acid, creatinine, sodium, potassium, chloride, calcium).
