Factors influencing development of management strategies for the Abou Ali River in Lebanon. I: Spatial variation and land use
No full textSurface water bodies are progressively subject to increasing stress as a result of environmentally degrading processes primarily related to anthropogenic activities. This study assesses and examines the impact of land use and anthropogenic activities on the spatial variation in water quality of the Abou Ali River in North Lebanon. It is the first detailed study of its kind in Lebanon and adds to the existing Knowledge by shedding light on a relatively small Mediterranean river in a developing country where there is a paucity of such studies. The assessment was conducted at the end of the dry season in 2002 and 2003 and the end of the wet season in 2003 and 2004. The study has demonstrated the importance of anthropogenic influences on the water quality of the Abou Ali River Basin, as concentrations of most contaminants were higher at locations with greatest human activity. The most adversely affected area was the section of the river that flows through an entirely urbanized and highly populated region, the Tripoli conurbation. Upstream rural sites were enriched by contaminants primarily from non-point sources such as agricultural runoff and poultry litter whereas contaminant concentrations at the urban sites were enriched by a combination of sewage discharge and flow of contaminants from upstream. If the Abou Ali River is to be utilized as a managed water resource and its water quality sustained, point source discharges will require treatment and land use management must be planned to minimize the impact of diffuse source pollution on the river. A high priority should be given to the implementation and enforcement of the precautionary and polluter pays principles. Moreover, an effective legal, economic and institutional framework is required to encourage investment in waste reduction and control and to introduce environmentally sound practices

Prospective evaluation of the impact of sonography on the management and surgical intervention of neonates with necrotizing enterocolitis
No full textBackground/aimEstablished indications for surgery in necrotizing enterocolitis (NEC) are pneumoperitoneum and failure to improve or clinical deterioration with medical treatment alone. It has been proposed that infants with intestinal necrosis may benefit from surgery in the absence of one of these indications yet the diagnosis of definitive intestinal necrosis is challenging. Recent data suggest that abdominal ultrasound (US) examination focused on the gastrointestinal tract and the peritoneal cavity may be of utility in this regard. The aim of this study was to evaluate the ability of abdominal US to detect intestinal necrosis in infants with radiographically confirmed NEC.MethodsTwenty-six consecutive infants with Bell stage II or III NEC were prospectively included in the study between September 2013 and July 2014. Infants with a pre-existing indication for surgery were excluded. At least one abdominal US examination was performed in each patient using a standardized previously described method. Surgery was performed at the discretion of the attending surgeon based on clinical and imaging findings. Clinical, radiographic, US, and intra-operative data were recorded to allow comparison between US findings, surgical findings and outcome.ResultsUS demonstrated signs of intestinal necrosis in 5 of the 26 patients. All of these five had laparotomy. Intestinal necrosis requiring resection was confirmed in four and the other was found to have NEC but no necrosis was identified. In 21 patients US did not suggest intestinal necrosis. Of these, only one had surgery in whom NEC but no necrosis was identified. The remaining 20 responded to medical treatment for NEC and were assumed not to have had intestinal necrosis based on improvement without surgical intervention. The sensitivity, specificity, positive predictive value and negative predictive values of US for the detection of bowel necrosis were calculated as 100, 95.4, 80.0, and 100 %, respectively.ConclusionOur prospective findings suggest that abdominal US can identify those infants with NEC who may need surgery by detecting bowel necrosis (prior to the development of perforation or medical deterioration) with high sensitivity and specificity. Early surgical intervention in the clinical pathway of NEC may lead to improved outcomes

The 10-week study period comprised a 2-week single-blind placebo run-in period followed by add-on treatment with AKL1 or placebo twice daily for 8 weeks. The primary study endpoint was the change from week 0 to week 8 in cough-related health status, as assessed by the LCQ.Results: Of 33 patients enrolled, 20 were randomized to AKL1 and 13 to placebo. Patients included 19 (58%) men and 14 (42%) women of mean (standard deviation [SD]) age of 67 (9.4) years; 15 (45%) patients were smokers and 16 (49%) were ex-smokers. The mean (SD) change from baseline in LCQ score at 8 weeks was 2.3 (4.9) in the AKL1 group and 0.6 (3.7) in the placebo group, with mean difference in change of 1.8 (95% confidence interval: –1.5 to 5.1; P=0.28). The St George's Respiratory Questionnaire score improved substantially in the AKL1 treatment group by a mean (SD) of –7.7 (11.7) versus worsening in the placebo group (+1.5 [9.3]), with mean difference in change of –9.2 (95% confidence interval: –19.0 to 0.6; P=0.064). There were no significant differences between treatment groups in change from baseline to week 8 in other patient-reported measures, lung function, or the 6-minute walk distance.Conclusion: Further study is needed with a larger patient population and over a longer duration to better assess the effects of add-on therapy with AKL1 in COPD.Keywords: Leicester Cough Questionnaire, anti-inflammatory, Picrorhiza kurroa, Ginkgo biloba, Zingiber officinal
Value proposition analysis for solid state lighting: A case study of Ahmedali Ahmed Electrical Contracting; Marketing the product in the Kingdom of Bahrain
No full textThe proposition given to a product or service in terms of its worth given by a customer is researched and analysed to find the underlying factors contributing to the value. The study is undertaken to investigate the different factors that lays ground for increased ‘Customer value’ and ‘Product Value’. The research objective is to find the “Value Proposition Analysis for Solid State Lighting: a Case Study AhmedAli Ahmed Electrical Contracting; Marketing the product in the Kingdom of Bahrain” Most businesses generate profits, when the customers give a certain value(s) to the service/product provided by the business entity. This could involve many attributes to consider. The project overlooks in to this value significantly to understand the attributes that collectively contributes to ‘Valued Relation’ between the customer and the business. This is achieved by making effective use of literature suggested by various authors and by employing research strategies to validate the literature through the findings. The research also looks in to the case study organisation to fully understand the capabilities of the company to market the product. Thus, this analysis will be specifically looking in to the value proposition given to Solid State Lighting by the current UK customers and by clients of AhamedAli Ahmed Electrical Contracting, Kingdom of Bahrain. However, this analysis must viewed critically, as the product comes at a premium price and the study will be much centred in the Kingdom of Bahrain and cannot be generalised for the other GCC countries or the Middle East. This study is focused to generate strategies in marketing Solid State Lighting in Bahrain taking A.A.E as the Case Study Organisation understanding the Value Proposition for Solid State Lighting

No full textRings whose RD-flat modules have restricted subflat domains
No full textA module KR is said to be RL-subflat if for every short exact sequence 0→U→D→L→0 of left R-modules, the sequence 0→K⊗U→K⊗D→K⊗L→0 is exact. The subflat domains of (RD-flat) modules somehow tells us how far (or how close) such a module is from being flat. Every right R-module is subflat relative to all flat left R-modules, and flat modules are the only ones sharing the distinction of being in every single subflat domain. A module is called f-test if it is subflat only to flat modules. Similarly, an RD-flat module is called tf-test if it is subflat only to torsion-free modules. In this paper, we consider two families of rings characterized by their RD-flat modules: those whose finitely presented RD-flat modules are either flat or tf-test (property (P)) and those whose finitely presented RD-flat modules are either torsion-free (flat) or f-test (property (Q)). Structural properties of both classes of rings are studied. © The Author(s), under exclusive licence to Springer-Verlag Italia S.r.l., part of Springer Nature 2023
MILLI EĞITIM BAKANLIĞI YABANCI DIL OLARAK İNGILIZCE DERS KITAPLARINDA STRATEJI ÖĞRETIMI
No full textHızla değişen günümüzün dünyasında eğitim ve yabancı dil eğitimi kavramlarının
yeni anlamlar kazanması kaçınılmazdır. Yaşam boyu öğrenme yaklaşımı, eğitime
bütüncül bir dünya görüşü, çeşitliliğe saygı, özerklik ve öz farkındalığı destekleme,
öğrenme stratejilerinin kullanımını özendirme, bunların yardımıyla birden çok yabancı
dil öğrenmeye doğru rehberlik etme, bu bağlamda eğitim uygulamalarını değerlendirme
gibi yeni görüşler getirerek yeni açılımlar sağlayabilir. Yabancı dil eğitimi
bireylere kendi varlıklarını diğer varlıklarla karşılaştırma olanağını vermektedir,
bu da daha fazla hoşgörü ve saygıyı beraberinde getirmektedir; bu şekilde yeni bir
dünyanın ortaya çıkmasını mümkün kılabilir. Bu çalışma, yaşam boyu sürecek bir
yabancı dil öğretimi bağlamında yabancı dil öğrenme stratejilerinin Milli Eğitim
Bakanlığı tarafından kullanılan yabancı dil olarak İngilizce ders kitaplarında nasıl ve
ne ölçüde kullanıldığını örneklemeyi amaçlamaktadır. Bu makale çerçevesinde alanda
kabul gören yabancı dil öğrenme strateji sınıflandırmalarından yararlanılarak bir
çerçeve oluşturulmuştur. Bu çerçeve ile Milli Eğitim Bakanlığı okullarında yaygınca
kullanılan dördüncü sınıftan onuncu sınıfa kadar olan yedi kitap seçilmiş ve incelenmiştir.
İnceleme sonucunda en çok bilişsel stratejilerin kullanıldığı etkinliklerin en
az da üstbilişsel stratejilerin kullanıldığı etkinliklerin kullanıldığı bulgulamıştır. Bu
sonuçlar çerçevesinde sözü edilen kitaplarla eğitim gören öğrencilerin yaşam boyu
sürecek bir yabancı dil öğrenimine hazır olup olmadıkları, özellikle de stratejilerin
kitaplarda örtük olarak verilmesi, vurgulanmaması ve kullanılan stratejilerin de
çeşitlilik arz etmemesi bağlamında tartışmalı hale gelmektedir
