In the running process, changes in the openness of the inlet one-way valve cause changes in the running parameters of the two impellers and in the inner flow field, thereby inducing pressure fluctuation and intensifying unit vibration. In this study, the change law of internal flow of the series-parallel centrifugal pumps was disclosed under different openness degrees of the inlet one-way valve and its internal relationship with pressure fluctuation was clarified by combining numerical simulation and model experiment. The major causes of pressure fluctuation and hydraulic performance changes induced by changes of internal flow field were analyzed. Results show that when the openness of the one-way valve is smaller than 20°, the two impellers present different operational states under parallel connection, which deteriorate the hydraulic performance of pumps. Decreasing the openness of one-way valve can reduce the pressure around the inlet of the second-stage blade and induce eddies; however, it slightly influences the pressure at the inlet of the first-stage blade. With the changes in the openness of the inlet one-way valve, the fluctuation frequency at the occurrence of maximum fluctuation remains the same; however, the fluctuation amplitude changes considerably. The fluctuation amplitude under small openness is lower than that under large openness. Conclusions obtained in the study have important implications in reducing the vibration and noise of series-parallel centrifugal pumps.

It is estimated that the prevalence of diabetes in Kenya is at 5% among adults. Although the care regimen is complex, patients with good diabetes self-care behaviors can attain excellent glycemic control. It is vital that patients adhere to their stipulated routines to minimize the burden of the disease on the healthcare systems. The objective of this study was to determine the association between socio-economic and demographic factors with adherence to dietary guidelines among Type 2 diabetes mellitus (DM) patients in Moi Teaching and Referral Hospital (MTRH), Eldoret. A cross-sectional study with mixed methods was conducted among 313 Type 2 DM patients at MTRH. Systematic random sampling was used to select the participants,while purposive sampling was used to select 6 key informants and 50 patients who participated in a Focus Group Discussion (FGD...

It is estimated that the prevalence of diabetes in Kenya is at 4.6% among adult patients. Although the care regimen is complex, patients with good diabetes self-care behaviors can attain excellent glycemic control. It is vital that patients adhere to their stipulated routines to minimize the burden of the disease on the health care systems. The purpose of this study was to determine adherence to dietary guidelines and dietary patterns among type 2 diabetic patients at Moi Teaching and Referral Hospital (MTRH), Kenya. Methods: A cross sectional research design with mixed methods approach was used and included a total of 313 respondents with type 2DM at MTRH. Systematic random sampling was used to select type 2 diabetic patients from the outpatient clinic while purposive sampling was used to select key informants and patients for Focus Group Discussion. Descriptive and inferential statistics was used to analyze the ...
