Biomass moulding fuel is an environmentally friendly and renewable energy source. We studied an independently-developed automatic flue-cured tobacco furnace, employing a biomass fuel source and studied the effect of biomass moulding fuel onbacco flue curing. We found that 1 kg of dried tobacco required 1.2 kg of biomass moulding fuel (heating value = 3550 kcal per kg). The energy input cost was 1.43 RMB** (fuel and electricity) and the labor cost was reduced by 75%, a reduction of 18.6% compared to the cost of burning coal. With respect to the environmental impact, the average emission concentration of smoke in the exhaust gas from the furnace was 16.2 mg/m3, SO2 was 13.6 mg/m3, and NOx was 2.3 mg/m3. Ringelmann blackness was less than 1. Compared to burning coal, all emissions were very low, demonstrating that the biomass moulding fuel furnace saved energy and reduced emissions compared to coal. In addition, the quality of cured tobacco and economic index were significantly improved.

Background The global utilization of the physician assistant/associate (PA) is growing. Their increasing presence is in response to the rising demands of demographic changes, new developments in healthcare, and physician shortages. While PAs are present on four continents, the evidence of whether their employment contributes to more efficient healthcare has not been assessed in the aggregate. We undertook a systematic review of the literature on PA cost-effectiveness as compared to physicians. Cost-effectiveness was operationalized as quality, accessibility, and the cost of care. Methods and findings Literature to June 2021 was searched across five biomedical databases and filtered for eligibility. Publications that met the inclusion criteria were categorized by date, country, design, and results by three researchers independently. All studies were screened with the Risk of Bias in Non-randomised Studies—of Interventions (ROBIN-I) tool. The literature search produced 4,855 titles, and after applying criteria, 39 studies met inclusion (34 North America, 4 Europe, 1 Africa). Ten studies had a prospective design, and 29 were retrospective. Four studies were assessed as biased in results reporting. While most studies included a small number of PAs, five studies were national in origin and assessed the employment of a few hundred PAs and their care of thousands of patients. In 34 studies, the PA was employed as a substitute for traditional physician services, and in five studies, the PA was employed in a complementary role. The quality of care delivered by a PA was comparable to a physician’s care in 15 studies, and in 18 studies, the quality of care exceeded that of a physician. In total, 29 studies showed that both labor and resource costs were lower when the PA delivered the care than when the physician delivered the care. Conclusions Most of the studies were of good methodological quality, and the results point in the same direction; PAs delivered the same or better care outcomes as physicians with the same or less cost of care. Sometimes this efficiency was due to their reduced labor cost and sometimes because they were more effective as producers of care and activity.

Mechanical transplanting is an emerging technology in Bangladesh agriculture. Deadong DP480 rice transplanter was used to conduct the experiment which is imported from South Korea and China. The performance of this machine needs to be thoroughly investigated in local condition. This experiment was conducted in Boro (2015) season in the farmers’ field at Gosaidanga in Shailkupa upazila under Jhenaidah district and at Rashidpur in Mithapukur upazila under Rangpur district. Two treatments, i.e. T1 = Hand transplanting (HT) and T2 = Mechanical transplanting (MT) were used in the experiment. The experiment was carried out in randomized complete block design (RCBD) and replicated in six plots in each location. Rice variety BRRI dhan28 was used to conduct the experiment in both locations. Fuel consumption of 4-row walking type mechanical transplanter obtained 5.25 L/ha. The field capacity and field efficiency of rice transplanter   obtained 0.11-0.12 ha/hr and 64-70 percent, respectively. Conventional seedbed preparation required 37-55 man-hr/ha whereas 71-77 man-hr/ha required in mat type seedling suitable for mechanical transplanting. Labor requirement in hand and mechanical transplanting ranged from 123-150 and 9.0-10.5 man-hr per hectare which was 19-22 and 1.65-2.00 percent of total labor requirement in rice cultivation, respectively. Number of seedling tray requirement ranged from 215-230 per hectare. Calibration should be done on space and seedling density setting before operation in each plot to get optimum plant spacing and seedling tray requirement. Missing hill obtained 1-2 percent in mechanically transplanted plot. Mechanically transplanted plot showed significantly the higher grain yield (9-14%) than hand transplanted method due to use of infant seedling. The input cost in the form of labor and material was found similar in hand transplanting whereas in mechanical transplanting, labor cost found 12 percent lower than material cost. The cost of growing mat type seedling for mechanical transplanter found 53 percent whereas the cost of raising traditional seedbed found 34 percent of the cost of hand transplanting. Mechanical transplanting reduced 1.8 percent input cost than hand transplanting in crop cultivation. BCR of MT and HT showed 1.18-1.19 and 1.03-1.06, respectively. Mechanical intervention in crop production drastically reduced the labor requirement which can offset the peak labor demand. Mechanical transplanting systems increased yield, improved labor efficiency, ensured timeliness in operation and faster transplanting.Progressive Agriculture 27 (3): 369-382, 2016

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

The Cost

The public has ever-rising expectations for the environmental quality of the North Sea and hence of everreducing anthropogenic inputs; by implication society must be willing to accept the cost of reduced contamination. The chemical industry accepts that it has an important part to play in meeting these expectations, but it is essential that proper scientific consideration is given to the potential transfer of contamination from one medium to another before changes are made. A strategy for North Sea protection is put forward as a set of seven principles that must govern the management decisions that are made. Some areas of uncertainty are identified as important research targets. It is concluded that although there have been many improvements over the last two decades, there is more to be done. A systematic and less emotive approach is required to continue the improvement process.
