Dietary intake and prevalence of metabolic syndrome among tanker truck drivers in Ghana

Purpose This study aims to assess dietary intake and prevalence of metabolic syndrome (MetS) among tanker truck drivers in the Kumasi metropolis, Ghana. Design/methodology/approach A cross-sectional study design enrolled 212 fuel tanker drivers. Sociodemographic, anthropometric, dietary and biochemical data were collected. MetS was assessed using the National Cholesterol Education Program Expert Panel on detection, evaluation and treatment of high blood cholesterol in adults Adult Treatment Panel III (NCEP ATP III) 2005 criteria. A three-day 24-h dietary recall was used to assess dietary intake. Binary logistic regression analysis was performed to determine the predicting factors of MetS among study participants. Findings The prevalence of MetS was 19.6% according to NCEP ATP III criteria. The prevalence of obesity, high BP, hyperglycaemia, dyslipidemia among participants were 7.5, 39.7, 37.7 and 57.3%, respectively. The energy intake for 176 (88.4%) of the participants was inadequate. The predicting factors of MetS were age (OR: 1.3, p = 0.04), glycated haemoglobin (OR: 9.6, p = 0.004), systolic blood pressure (OR: 1.2 95%, p = 0.01) and service years (OR: 0.8, p = 0.01). Research limitations/implications The current study focused on MetS among tanker truck drivers in Kumasi metropolis, which makes the current findings only limited to drivers of tanker truck within the municipality. Additionally, the 24-h dietary recall could be subjected to recall bias. However, the study is still of relevance as it becomes the first to target such a group within the municipality, taking into consideration the importance of these tanker truck drivers in driving the economy of Ghana. Originality/value This study highlights dietary intake and MetS among fuel tanker drivers previously underreported in the Ghanaian population. Findings of this study would inform further studies on lifestyle-related determinants of MetS among other cohort of drivers in other settings within the country.

ANALISA PRODUKTIVITAS DAN BIAYA OPERASIONAL ALAT BERAT PADA PROYEK PEMBANGUNAN STREET-RACE CIRCUIT MANDALIKA

The hourly productivity for structural cut with a depth of 2 to 4 meter of excavator is 17.778 m3/h and dump truck 11.755 m3/h. The excavator production for stockpiling from excavated sources is 30.521 m3/h, dump truck 13.171 m 3/h, motor graders 1839.780 m 3 /h, vibrator roller 90.414 m 3 /h and water tankers truck 71,142 m 3/h. Motor grader production for road body preparation work is 362,222 m3/h, vibrator roller 126,851 m3/h and water tanker truck 62,250 m3/h. The hourly operating cost for the excavator is Rp. 718,048,581, motor grader Rp. 670,416,081, vibrator roller Rp. 609,423,907, and water tanker truck Rp. 380,806,081. The income and profit from the use of heavy equipment are Rp. 39,488,806,755 and Rp. 3,589,981,523.05.

Hinterlands of Budget Air Travel. Investigating the Journey of Aviation Fuel

This paper investigates the oil infrastructures, as intersections of trans-territorial networks systems of power and their exchange with local practices: the journey of Jet A1 aviation fuel that facilitates thebudget air traveling in Berlin's airports, from crude oil extraction in Russia, distillation in Schwedt -Eastern Germany, to refueling off the aircraft by tanker truck sits source to its point of use. A case study focuses on the urbanism dynamics of Schwedt as an attempt to trace part of the planetary urbanism corresponding to Berlin's growing tourist industry's use of jet fuel. The first part of the research centers on oil landscapes' networks -the industrial footprint of oil: its transformation, storage, and transportation. Further provides a depiction of 'what constitutes aviation fuel and its production network' to view the actors involved in the process, the links between them, and the spatial implications. The second part addresses how aviation fuel has impacted Berlin and Brandenburg's hinterland: primarily, Schwedt, a shrinking city despite Berlin's recent boom, where the size of the traditional urban "city" form is diminutive in scale compared to the adjacent PCK oil refinery's "non-city" form of urbanization. The study's findings present new ways of interpreting and mapping the metabolic vehicles of planetary urbanization in both architectural and urban scales.

Forecasting the influence of vehicle columns with liquid cargoes on bearing systems in agriculture

Studies have been performed to evaluate the dynamic effect of columns of the same type of agricultural tanker truck on the beam-bearing systems of transport structures during movement in braking mode. The design scheme of the general oscillatory system is selected, a mathematical and numerical model of its behavior is developed, an algorithm for joint nonlinear oscillations is constructed. On the basis of the developed expert models, a computer complex was created using the simulation package of dynamic and event-driven systems Simulink MATLAB systems. Using it, a series of computational experiments was carried out to simulate situations of passage of convoys of cars with different parameters and with different driving modes. Various parameters varied: the speed of the column, the distance between the cars, the speed at the time of the start of braking, the place where the first car began to brake, the amount of steady deceleration, the number of tank compartments, and the value of operational underfilling. Based on the analysis of the results of numerical studies, the features of the dynamic effect of vehicles convoys carrying liquid cargo on load-bearing systems from the standpoint of the emergence of excess dynamic pressure on transport facilities and the need for its consideration are shown. Cases of a dangerous combination of parameters and driving modes are highlighted, and the need to distinguish such columns in a special class of moving load is shown. A significant increase in the dynamic coefficients of deflections in comparison with solid loads is shown. The need for full-scale research in this area with the aim of introducing amendments to regulatory documents has been proved.

Methane Emissions Reduction in Liquefied Natural Gas Off-Loading Process in Refueling Stations

Recent research into methane emissions from the liquefied natural gas (LNG) supply chain has revealed uncertainty in the overall greenhouse gas emissions reduction associated with the use of LNG in heavy-duty vehicles. Methane is the main component of natural gas and a potent greenhouse gas. This study investigates the impact of five methods used to offload LNG from a tanker truck to an LNG refueling station and estimate the amount of fugitive methane emissions. The LNG offloading process time, and the final pressures of the tanker truck and refueling station are considered to evaluate the performance of the LNG offloading methods. The modeling results show that the LNG transfer by using a pressure buildup unit has a limited operating range and can increase methane emissions by 10.4% of LNG offloaded from the tanker truck. The results indicate that the LNG transfer by using a pump and an auxiliary pressure buildup unit without vapor return provides the shortest fuel offloading time with the lowest risk of venting methane to the atmosphere.
