Background Clinical pharmacists are the primary source of scientifically valid information and advice on the safe, rational, and cost-effective use of medications. However, ward-based clinical pharmacy services are not well optimized in Northern Cyprus. Objective Ward based clinical pharmacy services were introduced and evaluated in cardiovascular clinics. Setting Cardiology and cardiovascular surgery departments in a tertiary university hospital. Methods A prospective interventional study introduced and documented clinical pharmacy services for 120 days. Drug-related problems were classified using the Pharmaceutical Care Network Europe PCNE DRP classification tool V6.2. Main outcome measure Interventions proposed and acceptance rate of recommendations. Results A total of 133 patients were reviewed, and, 81 patients had drug-related problems. Only 402 (93.1%) of the 432 suggested interventions were accepted and regarded as clinically relevant. Drug-related problems primarily involved antihypertensive, diuretic, and antithrombotic agents. Treatment effectiveness was the major type of drug-related problems (107; 49.3%) followed by adverse drug reactions (74; 34.1%). Drug dose and selection were the most frequent causes of drug-related problems. Add/change/stop medications were the most common types of intervention at the prescriber level. A total of 171 (78.8%) of the identified 217 drug-related problems were solved, 4 (1.8%) of the problems were partially solved, 32 (14.7%) problems were unsolved, and 10 (4.6%) problems had unknown outcomes. Conclusion Clinical pharmacy services may have optimized therapy effectiveness and prevent adverse effects. The pharmacist interventions were highly accepted by cardiologists; this may indicate the presence of a great opportunity and need to optimize and implement CPS in other hospitals in Northern Cyprus.

Recently, fiber has been incorporated into concrete mixtures, where its distribution in the concrete matrix helps to improve and enhance the mechanical properties of fiber-reinforced concrete (FRC). The aim of this study is to investigate the influence of steel and synthetic fiber parameters, along with different coarse aggregate maximum sizes (CAMZs) on FRC performance. Additionally, in past research, the empirical relationships among the compressive, tensile, and flexural strengths of plain concrete and FRC were assessed, and correlations between these mechanical properties of FRC were examined. For each CAMZ, four fiber dosages for each fiber type were considered. The results demonstrate the mechanical properties of FRC enhanced as the fiber length increased from 13 mm to 60 mm, the CAMZ increased from 9.5 mm to 37.5 mm, and the ratio of the fiber length to the CAMZ was in the range of 0.35–5.68. All mixtures have been intended to exhibit similar compressive strengths; however, the synthetic/steel fiber advanced the brittleness ratio of specimens with G10, G19, and G38 to approximately 36.8%, 40.7%, and 47.4% greater than the contral specimens, respectively. In addition, from the regression analysis investigation, there are strong correlations from the regression analysis of the mechanical property results of FRC.

The sulfate issue in fine aggregate grows with time and it is not easy to gain a fine aggregate with sulfates amount within the specifications of Iraqi standard. Internal sulfate attack is regarded as a significant problem in concrete construction in Iraq and the Middle East countries. One of the modern generations in ultra-high performance concrete is Reactive powder Concrete (RPC) that has been prepared for cemented materials using microstructure improvement methods. RPC has gained attention from both academia and engineering fields with extensive applications. This study presents an experimental research on the impact of Rice Husks Ash (RHA) as replacement percentage of cement upon some mechanical features of RPC with high sulfate content in fine aggregate (Three percentages of SO 3 = 0.16, 0.5 and 1.2%). Three percentages of RHA (0, 10 and 15%) as a partial substitution of cement weight have been used in this research. The compressive and the flexural strengths have been adopted to attain the impact of adding RHA. The outcomes have showed that the incorporation of RHA has an important influence on the compressive-strength for both with and without internally sulfate attacking. The result has indicated that using 10% of RHA as a partial cement substitution has increased the effectiveness of RPC by its mechanical features (compressive and flexural-strengths) without internal sulfate attacked.

Large quantities of paper and wood waste are generated every day, the disposal of these waste products is a problem because it requires huge space for their disposal. The possibility of using these wastes can mitigate the environmental problems related to them. This study presents an investigation on the feasibility of inclusion of waste paper ash (WPA) or wood ash (WA) as replacement materials for fly ash (FA) class F in preparation geopolymer concrete (GC). The developed geopolymer concretes for this study were prepared at replacement ratios of FA by WPA or WA of 25, 50, 75 and 100% in addition to a control mix containing 100% of FA. Sodium hydroxide (NaOH) solutions and sodium silicate (Na2SiO3) are used as alkaline activators with 1M and 10M of sodium hydroxide solution.The geopolymer concretes have been evaluated with respect to the workability, the compressive strength, splitting tensile strength and flexural strength. The results indicated that there were no significant differences in the workability of the control GC mix and the developed GC mixes incorporating WPA or WA. Also, the results showed that, by incorporating of 25–50% PWA or 25% WA, the mechanical properties (compressive strength, splitting tensile strength and flexural strength) of GC mixes slightly decreased. While replacement with 75–100% WPA or with 50–100% WA has reduced these mechanical properties of GC mixes. As a result, there is a feasibility of partial replacement of FA by up to 50% WPA or 25% WA in preparation of the geopolymer concrete.
