The Impact

Purpose of the present research is to improve the quality of cleaning sugar beetroot crops with a brush cleaner by developing a device for removing stuck soil. The article defines the dependence of the impact velocity on the distance to the place of impact, which changes linearly, increasing with increasing distance to the place of impact. Analysis of the dependence shows that the speed can be most significantly influenced by the speed of the conveyor and the radius of the trajectory of the end of the bending lint, which directly depends on the diameter of the cylindrical brush. Nomogram was obtained to determine the most optimal parameters of the impact site on the lint. When conducting studies with heavy loamy chernozem soils with a moisture content of ≈28%, it revealed that the minimum required brush lint impact velocity to separate soil from the coils of the spring is about ≈ 2.5 m/s. The analysis of the dependence shows that the most effective cleaning of the brush lint from the stuck soil (90-98%) occurs when a blow is applied at a distance of 40 to 78 mm from the place of attachment of the lint with a lint length of 100 mm. The impact velocity of the brush lint should be large enough to separate the soil of maximum stickiness from the coil of the spring, however, it should not be greater than the speed causing lint cutting, i.e. the speed at which the brush lint are destroyed.

Parking Demand

Pricing is a common measure for parking demand management that has been implemented worldwide. However, the impact of parking price on a parking lot’s quality of service is seldom discussed. This study investigated the impacts of a ladder daily maximum fee charging strategy on the quality of service of the Hongqiao International Airport parking lot based on automatic transaction data before and after the strategy was implemented. An evaluation framework considering managers’ and users’ perspectives was designed. The estimation results show that the new price regulation method largely discouraged long-term parking demand and improved the availability of airport parking facilities, especially during long holidays. As a consequence, throughput and income largely increased in the airport, and there were extra time costs during vehicle departures. The price elasticity of parkers with different parking durations was further estimated. The results showed that price sensitivity is relatively inelastic but varies based on parking duration.

The quality of honey are naturally differs depending on its geographical origin and the botanical source of honeydew collected by the bees. These characteristics influence the physical appearance of honey such as its colour lightness and liquid thickness; which then may influence the honey attractiveness to the consumers. The thickness of honey is correlate with its moisture content. The higher the moisture content of honey, the higher the risk of fermentation, thus honey is commonly process before marketed. However, the processing methods may change the nutritional content, original taste and physical characteristics of the honey. This paper reviews the effect of five types of processing methods on the quality of honey; which are the spray-drying process, thermal treatment technique, thermosonication technique, high-pressure processing technique and microwave processing method. Overall, it can be concluded that all processing methods reviewed in this article altered the nutritional quality and physicochemical characteristics of honey. However, the different processing methods may alter the quality of honey differently. This information is very important for consumer to understand the reasons on the variability of honey quality in the market. It also will help the honey industry players to choose the best method in processing their honey and ensuring the best quality of honey can be produce to fulfil the consumers need and satisfaction.

Moderate Climate

In Poland, under conditions of the moderate climate and transition between maritime and continental climates, the average rainfall totals of the growing season are in the range of 350–400 mm; however, they are distinguished by great temporal and spatial variability. Climatological studies demonstrate that the drought frequency is approximately 30%. Therefore, under such conditions, irrigation has a supplementary and intervention nature and is applied only when dry periods occur. The aim of this study was to determine the impact of sprinkler irrigation and increased nitrogen fertilization on the yield and quality of sugar beet roots and yield of sugar. The average increase of the yield under irrigation was 18.1 t·ha−1 which constituted a 22.8% increase in the yield. Furthermore, there was a marked tendency of a higher sugar content in the roots of irrigated plants. The absolute, relative, and unit average sugar beet root yield increases obtained under the influence of sprinkler irrigation and the lack of a significant diversity in the sugar content in roots confirm that irrigation contributed to an appropriate pace of plant growth and development. The increased rate of nitrogen fertilization (N2) of 160 kg N·ha−1 plus an additional 40 kg N·ha−1 resulted in the significantly greater root yields compared to the control (N1) (160 kg N·ha−1), i.e., an average of 7.6 t·ha−1 (9%). Based on the crop-water production function, the maximum root yields were obtained for the N1 rate at a total precipitation and irrigation amount of 382 mm, compared with 367 mm for the N2 rate.

Feedstock degradation is a major source of financial risk for cellulosic biorefineries. To assess the impact of the feedstock loss and quality during storage, this study explored interactions of moisture content and temperature on the degradation of biomass. Specifically, this study evaluated the dry matter loss and compositional change of corn stover during storage conditions common at industrial biomass storage facilities. This lab-scale study allowed for increased measurement precision associated with quantifying how biomass degradation changes the quality of stored biomass. Results of this work define stable biomass storage moisture content of less than 20% in which there is low risk for degradation over time. At moisture levels above 20%, biomass degradation will be prevalent with hemicellulose being the most degraded fraction of the feedstock. Additionally, results demonstrate that temperature has a minimal impact on biomass degradation in non-frozen storage conditions.

The objective of this experiment was evaluate of the impact damage to pinto bean seeds where seed moisture content (9.25, 12.51, 15.01, 17.52, 20.01% wet basis), impact velocity (5.5, 8, 10, 12.5 and 15m/s) and seed orientation (end and side) were independent variables. The study was conducted under laboratory conditions, using an impact damage assessment device. The results showed that impact velocity, moisture content and seed orientation significantly influenced the physical damages of pinto beans at 1% level. Increasing the impact velocity from 5.5 to 15m/s caused an increase in the mean values of damage from 0.39 to 37.30%. With increase the moisture content from 9.25 to 17.52%, the mean values of percentage of damaged beans decreased significantly from 41.24 to 4.27%. However, by a higher increase in the moisture from 17.52 to 20.01%, the mean values of physically damaged beans showed a nonsignificant increasing trend. There was an optimum moisture level of 17.52% at which seed damage was minimized. The relationship between the percent of physical damage with impact velocity and beans moisture content was expressed mathematically. It was found that the percentage damage to seeds was a quadratic function of moisture content and impact velocity. Impact to the end of the seeds (18.62%) produced the higher damage than side orientation (13.12%).

One way to improve compost quality of typical organic waste is by addition of additive such as wood chips. This study aims to analyze the impact of the wood chips addition (ratio 1:10) on compost quality of typical organic waste (fruits, vegetables, yard waste, and food waste) in home composter, and to compare the compost quality with the standard of domestic compost according SNI 19-7030-2004. Analysis was conducted on composts raw material, compost maturity process in every 5 days measurement, and on compost product. Analysis of compost product of typical organic waste with addition of wood chips showed that parameters of temperature, moisture content, and pH of vegetables and yard waste has complied the standard whilst parameter of C/N ratio has not complied. The addition of wood chips caused the drop of compost temperature and moisture content, resulted in the decomposition process located in aerobic condition, resulted in production of compost in form of humus in greater volume. The addition of wood chips also caused the compost pH and C/N ratio increased.Keywords: compost quality, home composter, typical organic waste, wood chipsAbstrakSalah satu upaya untuk memperbaiki kualitas kompos sampah organik adalah dengan penambahan bahan aditif, seperti serpihan kayu.

Abstract Beluntas leaves are medicinal plants with pharmacological effects, such as antioxidant, antidiarrheal, antidiabetic, and antibacterial. Drying is one of the processes before the beluntas leaves are consumed. However, drying could degrade the quality of beluntas leaves. This research aims to investigate the impact of drying conditions on the physical qualities of dried beluntas leaves. Beluntas leaves with a moisture content of 83-90% were dried using drying methods, namely the greenhouse effect dryer (ERK), cabinet dryer (CD) at 40, 50, 60, and 70°C, and freeze dryer (FD) at 35, 45, and 55°C. The physical parameters measured were moisture content, color, shrinkage, rehydration ratio, and bulk density. The results showed that the final moisture content of the dried beluntas leaves were 8.40; 4.92-10.70; 4.73-6.77%w.b for ERK, CD, and FD, respectively. Page’s model was suitable for explaining the changes in moisture ratio during the drying process (R 2 = 0.9934 − 0.9999). The freeze-drying method can preserve the leaves’ color and obtain the lowest moisture content with a low drying temperature compared to other methods. Freeze-dried beluntas leaves also exhibited the highest rehydration ratio, which was 2.03 – 2.25.

Mechanical damage of seeds due to harvest, handling, and other processes is an important factor that affects the quality and quaintly of seeds. This study evaluated impact damage to the mung bean seeds with moisture contents of 9.54 to 25% wet basis and subject to impact velocities from 10 to 25 m/s using a laboratory impact damage assessment device. The results showed that impact velocity, moisture content, and the interaction effects of these two variables significantly influenced the percentage physical damage in mung ban seeds (p<0.01). Increasing the impact velocity from 10 to 25 m/s caused a significant (p < 0.05) increase in the mean values of damage from 0.53 to 31.78%. The mean values of physical damage decreased significantly (p < 0.05) by a factor about two (from 22.41 to 11.24%), with increase in the moisture content from 9.54 to 20%. However, by a higher increase in the moisture from 20 to 25%, the mean value of damage showed a non-significant increasing trend. There was an optimum moisture level of 20%, at which seed damage was minimized. An empirical model composed of seed moisture content and velocity of impact developed for accurately describing the percentage of physical damage to mung beans. It was found that the model has provided satisfactory results over the whole set of values for the dependent variable.
