The incidence of major chronic Non Communicable Diseases (NCD) medically diagnosed or treated, was studies in a cross section of Kuwait adult population as well as their daily levels of physical activity (PA) as recalled by the International Physical Activity Questionnaire, IPAQ. A group of 1957 subjects 17 - 65 years of age, representative of the Kuwait population was selected using last year high school students and their relatives as well as government workers in each Kuwait governorate. Descriptive statistics, frequency tables, chi square and Fisher tests were used. ANOVA or Mann Whitney and Kruskal-Wallis tests were used for comparisons. The percentage of subjects in the low categorical PA level (from IPAQ) is high (29.4%) even at a young age (17 - 24), similar in prevalence to overweight/obesity (30%). At age 45, obesity increases to 40% with little change in % subjects of low PA. Weighted average categorical PA was 1280 ***/week reflecting that the majority (40%) of subjects belonged to the moderate PA category. A high proportion (38%) of subjects in the 17 - 24 age category contributed to the observed level of PA activity. Incidence of overweight and obesity increased from 30 to more than 55% from the second to the sixth decade of life. Hyperlipidemias increased in incidence from 8% to 45% of the sample from the third to the sixth decades of age. Hypertension and diabetes increased from the 4th to the 6th decades of life to affect from 14% to 40% and from 10% to 36% of the studied population, respectively. Incidence of Heart Disease increased from 9% to 15% of the sample population, between the 5th and 6th decades of life. The data indicate a sequence of events, initiated by overweight and obesity as early as in the 2d decade of life, followed by hyperlipidemia in the 3d decade, diabetes and hypertension in the 4th, and heart disease in the 5th decade of life.

Practical Use of Stairs to Assess Fitness, Prescribe and Perform Physical Activity Training

Health 2016年第13期8卷 1402-1410页

Aim: Evaluating climbing stairs for prescription and implementation of physical activity regimes. Methods: Healthy females (F, n = 14), and males (M, n = 15) participated. By climbing 100 steps of stairs with 0.173 m height, Heart rate (HR) and oxygen uptake were measured throughout the floors;Blood pressure (BP) was measured at ground and the 5th floors only. Results: Energy increased from 2 to 7.6 was metabolic equivalents (METs = 3.5 ml O2/***) at 17.3 m elevation in 2 min. at the 5th floor, and percent Heart Rate Reserve (%HRR) was 66.17% in F and 48.7% in M, proportional to their aerobic efforts. Average climbing efficiency was 15.8 ± 2.3% (n = 29). Aerobic capacity estimated dividing the highest work rate (17.3 Kg.m/*** × 0.00239 = 0.0207 Kcal/***), by fractional effort (F = 0.6617, M = 0.487) and fractional efficiency (0.158), at 5 Kcal/L O2 was 0.040 in F and 0.054 L O2/*** in M. Minimum training intensity reached at the 3rd floor by F. In M the highest %HRR reached was 48.7% at the 5th floor, insufficient for training. Conclusions: Stairs used for submaximal evaluation of aerobic capacity and for target intensity prescription. Training, levels climbed, repetitions per day (if 5, 100 Kcal per day, ascending) and number of days/week are adjusted. Full regime requires up to 7.6 METs, a total of 532 and 140 ***/week ascending and descending, respectively. Intensities >7.6 MET, climbing rate should be >8.65 m/min. Limiting ascent to 1 (3.5 METs) or 2 (5.5 METs) floors or only descents (2 - 3 METs) may be used for unfit subjects. This method is useful for those with no access to sophisticated facilities.

Purification of Produced Water from a Sour Oilfield in South Kuwait. 1. Oil-Water Separation and Industrial Salt Production

引用

Journal of Water Resource and Protection 2024年第2期16卷 156-180页

Produced water from an oil extraction site in South Kuwait was sampled after primary oil – water separation had been carried out. The produced water was filtered through a mixture of activated charcoal and esterified cellulosic material gained from spent coffee grounds as a tertiary adsorption treatment. The earth-alkaline metal ions and heavy metals were separated from the de-oiled produced water by addition of either sodium or potassium hydroxide in the presence of carbon dioxide or by direct addition of solid sodium carbonate. The resulting filtrate gave salt of industrial purity upon selective crystallization on evaporation.

Intensive aeolian processes occur due to the scarcity of rainfall and lack of vegetation cover in arid regions. The study of recent surface sediments in arid areas is important for environmental assessments, evaluation of natural resources, and land use planning. In this study, two areas were chosen as they show changes in lithology, environment and landforms. The two study areas are al-Rawdatain in the northern part, and al-Managish in the southern part of Kuwait. The current study aims to define the sedimentomorphic zones in these areas, with an emphasis on Quaternary geomorphological evolution by providing an integrated approach based on satellite images, topographic maps, field measurements, and laboratory analysis. Remote sensing data were spatially analyzed to classify and detect the temporal changes in the surface sediments and geomorphology based on the field measurements (n = 42) as ground truthing points for supervising the classification. Samples from both areas were collected and subjected to grain size (dry mechanical sieving) and X-Ray Diffraction (XRD) analysis. The resulting data were statistically analyzed for grain size distributions and mineralogy based on the US standard set of sieves. The study found that the Aeolian sand sheet deposits are the most frequent recent surface deposits in Kuwait and cover most of the other sediments. The direction of movement of the sand sheets is from NW towards SE. The mineralogical composition of the aeolian recent surface sediments revealed that they are mostly derived from the Dibdibba Formation and Tigris-Euphrates fluvial terrace deposits. Quartz is the most frequent component of the studied surface sediments in the study areas (66%). The calcite mineral is also found in subordinate amounts in the study areas (10%).
