The Us

The rapid growth of corn-based dry grind ethanol plants over the past decade in the US has resulted in a great increase in production of the coproduct DDGS (distillers dried grains with solubles). Since some physical properties like low bulk density and poor flowability can impact the market potential of DDGS, pelleting of DDGS can be one of the easiest ways to improve this situation. Pellet quality is the focus of this project. The pelleting process was conducted with three initial DDGS moisture contents and two different dies; a total of six runs were completed to produce DDGS pellets. The physical qualities of pelleted DDGS were determined by measuring durability, bulk density, angle of repose, and color of the pellets. The results showed that the durability ranged from 42% to 89%, the highest pellet durability occurred when the moisture content was 20% db and the die diameter was 1/8 in. The bulk density increased when the DDGS moisture content decreased, and the highest bulk density was observed when the moisture content was 10% db and the die diameter was 1/8 in.

Two Factors

Turmeric (Curcuma longa L) in Indonesia is widely known as a herbal medicinal plant, food coloring, and food flavoring. The high water content of turmeric will shorten the storage time and the quality of the ingredients. The need for drying which is the process of removing the moisture content of the material with the aim of prolonging the shelf life. The use of the foam-mat drying method with the addition of adhesives aims to speed up the drying process and maintain the quality of a material. The result of drying turmeric obtained is turmeric powder product. This study used a completely randomized design (CRD) with two factors, namely the variation of the microwave oven power and the composition of the developer agent (ovalet). The research procedure was divided into two stages, namely the manufacture of powder and continued with the measurement of physical quality. The stages of making powder begin with the preparation of raw materials, stripping, size reduction, addition of developer, drying, then grinding. The second stage is measuring physical quality, namely fineness modulus, average grain size, powder moisture content, color, water absorption, oil absorption, and bulk density. The power variations used are 420 watts, 535 watts, and 680 watts, while the composition of the developer is 1%, 2%, and 4%. Data analysis using two-way ANOVA statistical test with two factors that affect the variation of power and composition of the developer (ovalet). FM values ​​ranged from 0.364 – 1.576, D values ​​ranged from 0.005 – 0.0012 mm, final moisture content values ​​ranged from 7.60 – 9.59%, powder moisture content values ​​ranged from 9.47 – 11.43%ww , L values ​​ranged from 61.46 – 65.96, a values ​​ranged from 13.54 – 16.05, b values ​​ranged from 48.21 – 52.42, DSA values ​​ranged from 2.78 – 3.54 ml/ g, DSM values ​​ranged from 1.22 – 1.60 ml/g, and DC values ​​ranged from 0.38 – 0.44 g/cm3. The combination treatment of drying power with developer is influenced by the drying power of the parameters, namely the value of moisture content, fineness modulus, average grain size, brightness level, redness level, yellowness level, oil absorption, water absorption, and bulk density. While the developer affects the finenes modulus, average grain size, yellowness level, and bulk density.

Heart failure (HF) is a leading cause of hospitalisation and healthcare costs worldwide. Acute decompensated heart failure accounts for more than 1 million hospitalisations in the US. Despite advances in the quality of acute and chronic HF disease management, gaps in knowledge about effective interventions to support the transition of care for patients with HF remain. Despite multiple trials of promising therapies, standard care consists of decongestion with IV diuretics and haemodynamic support with vasodilators and inotropes and this has remained largely unchanged during the past 45 years. Newer advances in medical innovations and structural heart disease interventions have now given promise to improved survival, outcomes and quality of life for patients with advanced HF of multiple aetiologies. In this article, we focus on structural interventions in the treatment of patients with HF.

Remarkable Progress

The article argues that China has achieved a remarkable progress in promoting technology absorption and innovation over the past decade. China today spends 2.1 percent of GDP on R&D, more than the OECD average. By 2020, China together with the US will be responsible for more than half of the world’s R&D spending. These two countries may thus largely de-cide about the speed and direction of mankind’s technological progress. Despite the pro-gress, however, China still faces several challenges to becoming a global technological giant. To face these challenges, China would be well advised to increase the quality of innovation outputs, strengthen efficiency of public support for innovation, further strengthen intel-lectual property rights, and help enhance managerial practices of Chinese firms.

Effect Of Moisture

<p>The effect of moisture content on some physical and mechanical properties of two varieties of tigernuts (<em>Cyperus esculentus</em>) was investigated. These properties include: geometric dimensions, linear dimensions, 1000 tuber weight, bulk density, tuber size, sphericity, angle of repose, porosity, coefficient of static friction and compressive strength. The moisture content levels used were 20, 25, 30, 35 and 40% wet basis (wb), and the two tigernut varieties used were yellow and brown types. The linear dimension, geometric diameter, sphericity, 1000- tuber weight, bulk density and angle of repose in both varieties increased with increasing moisture content. The average length, width and thickness of the yellow variety increases more than the brown variety at the determined moisture contents. True density of the yellow variety increased while the brown variety decreased with increase in moisture content. The porosity of the yellow variety reduces with increase in moisture content from 45.95 at 20% mc to 42.4 at 40% mc, while the brown variety decreased from 42.72 at 20% mc to 30.77 at 40% moisture content. The yellow variety had bigger size tubers than the brown variety and this has serious implications in packing, handling and transportation issues.</p>

Can one sell any positive value of Trump’s presidency to an academic audience? The editors of this special series invited polemical essays, but maybe asking readers to consider the merit of Trump is going a little too far? We put forward the argument here that as critical scholars we simply cannot allow ourselves to be swept up in the bien-pensant tide of Trump-trashing, which has almost become as addictive as the current reality-TV quality of the US presidency itself. As Roitman has suggested in a different context, ‘the concept of crisis is crucial to the “how” of thinking otherwise’. Thus, we believe it crucial to seize the crisis of the Trump presidency as an opportunity to activate the utopian imagination, rather than an occasion for moralizing judgements or regressive nostalgia which would effectively mean aligning ourselves with the neo-liberal consensus many of us spent our careers critiquing. We further argue that Fredric Jameson’s notion of the dialectic may refresh our critical conceptual arsenal in these disorienting times. This dialectical approach is meant to alter not only how we see reality, but also what we think we can do with it. It enables us to see the traumatic event of Trump’s election as providing a form and space through which contradictions that have been locked firmly into place in our socioeconomic set-up over the past few decades have become much more malleable, partly because of their increased visibility.

Health Field

During the past decade, ‘merger mania’ has been a striking trend in the US health field as a strategy to improve the integration of services, to reduce expenses, and to increase the ability of providers to manage risk-based payment. However, during the past quarter of a century limited operational and fiscal evidence has been published in both the health and general management literature that strongly supports the efficacy of horizontal mergers. This article further argues that a likely scenario over the next decade, in spite of disappointments among these mergers in effecting significant cost reductions, is for the US health networks to continue acquiring additional providers and insurers. After these alliances gain significant market penetration, they are expected to behave as oligopolists. For these mergers to eventually achieve their earlier projected savings, the health field's leadership will be forced to implement cost-cutting measures such as: more vigorously coordinating the network's key clinical services to reduce competition for revenues among the partners within an alliance, closing superfluous hospitals and centralizing expensive tertiary services, encouraging surplus physicians to relocate to under-served areas, and providing direction to carefully integrate the best elements of what the competitive and regulatory strategies are able to offer to improve access, social equity, quality of care, and to reduce total health expenditures.

The results of studies of the quality of food and non-food grain of wheat from the southern regions of Ukraine in 2016 harvest are presented. The indicators of the quality of wheat grain were determined, the uniformity of their distribution in different classes of wheat was assessed, the content of protein fractions of the gluten complex and the molecular weights of individual protein structures were determined. It was found that the studied 13 samples of wheat grain had the following quality indicators: moisture content 9.4 ... 13.5%, bulk density 731 ... 814 g/l, protein content 10.1 ... 13.2%, gluten content 16.4 ... 25.6%, gluten quality 50 ... 110 units of the IDK device, falling number 311 ... 493 s, grain admixture 1.2 ... 10.5%, grains damaged by a wheat bug, 0.1 ... 10.1%. It was noted that the bulk density of all samples of wheat of 2 ... 6 classes exceeded the standard values in each class. In terms of protein content, 2 from 3 samples of class 5 wheat and 1 from 2 samples of 6 class exceeded the standard value of class 3 wheat (≥11.0%). The same was observed for these samples and for the gluten content (≥18%). Almost all grain samples, except for 2 samples of the 5th class and 2 samples of the 6th class, met the requirements of wheat of the 2nd class (45 ... 100 units device VDK). The falling number of all samples was high and significantly exceeded the normalized value (180 s), even for class 2 wheat. It was found that the uniformity of the distribution of individual quality indicators in different classes of wheat grain by the coefficient of variation is not the same. Such indicators of grain quality as moisture content, bulk density and protein content in different samples of the south of Ukraine in 2016 harvest fluctuated weakly (V≤10%), in terms of the amount of gluten and the falling number fluctuations were average (10% ≤V≤20%). Fluctuations in the content of grain impurities and grains damaged by the wheat bug are big (V≥20%). For the last indicator, fluctuations relative to the average are very large and exceed 120 %. This indicates that in different areas where wheat was grown, the infestation by the wheat bug was very different. It was shown that regardless of the total amount of protein determined by the Infratec FOSS express analyzer, four protein fractions of the gluten complex (albumins, globulins, gliadins and glutenins) are present in all grain classes, and the molecular weights of the protein structures of the main fractions are within small limits, which are in kDa - for albumins and globulins 20...30, gliadins 27.. 100 and glutenins 30...35. It was noted that in the varietal wheat "Chernobrova" albumins and globulins have a slightly higher molecular weight (30...40 kDa) than in non-varietal wheat.

Wood Particles

The properties of particleboards and the course of their manufacturing process depend on the characteristics of wood particles, their degree of fineness, geometry, and moisture content. This research work aims to investigate the physical properties of wood particles used in the particleboard production in dependence on their moisture content. Two types of particles currently used in the production of three-layer particleboards, i.e., microparticles (MP) for the outer layers of particleboards and particles for the core layers (PCL), were used in the study. The particles with a moisture content of 0.55%, 3.5%, 7%, 10%, 15%, and 20% were tested for their poured bulk density (ρp), tapped bulk density (ρt), compression ratio (k), angle of repose (αR), and slippery angle of repose (αs). It was found that irrespective of the fineness of the particles, an increase in their moisture content caused an increase in the angle of repose and slippery angle of repose and an increase in poured and tapped bulk density, while for PCL, the biggest changes in bulk density occurred in the range up to 15% of moisture content, and for MP in the range above 7% of moisture content, respectively. An increase in the moisture content of PCL in the range studied results in a significant increase in the compression ratio from 47.1% to 66.7%. The compression ratio of MP increases only up to 15% of their moisture content—a change of value from 47.1% to 58.7%.
