Organoleptic Characteristics of Cookies from Sorghum Composites Flour

Application of wheat flour in various food products has increased the import of wheat flour over years. The use of domestically grown crops like Sorghum ( Sorghum bicolor L. Moench) could reduce the demand of wheat. Sorghum flour can be used in partial substitution with wheat flour for many food products, like cookies . The use of sorghum as cookies ingredient could be combined with other flours to get a composite flour. The purpose of this research was to obtain proportion of sorghum flour, sweet potato flour and soyabean flour that produce cookies with good organoleptic characteristics. The proportion of composite flour adequacy was calculated using a list of foodstuffs (DKBM). The research method was based on Experimental Method with Randomized Block Design (RBD) in twelve treatments and two repetitions. The treatments were proportion of sorghum flour (6 minutes, 8 minutes, 10 minutes of dehulling time), sweet potato flour, and soyabean flour. The results showed that cookies made with proportion of sorghum flour, sweet potato flour, and soyabean flour gave no significant difference in organoleptic characteristics (Overall, color, taste, aroma, and hardness). The result also showed that the characteristics of the cookies were not affected by dehulling of sorghum grains but influenced by other ingredient than flour. Keywords: Sorghum, Sweet Potato Flour, Soyabean Flour, Cookies, Sensory Properties
The Mental Well-Being of Health Care Professionals During the COVID-19 Pandemic

This research takes on a challenge to uncover a set of antecedents of health care professionals' mental well-being during Covid-19 pandemic in 27 European Union countries. Adopting the protection motivation theory and self-determination theory as frameworks, the present study examined whether the mental well-being of health care workers is determined by a combination of COVID-19 related factors (exposure and resources), organizational factors, and individual and attitudinal factors. Objectives: Adopting the protection motivation theory and self-determination theory as frameworks, the present study examined whether the mental well-being of health care workers is determined by a combination of COVID-19-related factors (exposure and resources), organizational factors, and individual and attitudinal factors. Methods: The present study is based on Eurofound's Living, Working, and COVID-19 survey, and the fieldwork for this survey was performed via uncontrolled convenience sampling throughout June and July 2020 in the 27 European Union countries. This research utilized a subsample of 1824 health sector employees and 11,750 workers in the other service industries. Further, to meet the objectives of this study, different linear regression models are estimated. Results: Despite the close contact of health care workers with COVID-19, we found that the risk of contracting the coronavirus does not explain their poor or high well-being. However, the availability of personal protection equipment and mistrust in the national health system contribute to well-being, along with other organizational (eg, job insecurity) and individual-attitudinal factors (eg, health and life satisfaction). Conclusions: The present study offers various valuable insights for health institutes, organizations, practitioners, and employers to combat COVID-19 and identify the determinants of the mental well-being of health care professionals.
DETERMINATION OF THE WETTING FRONT IN DRIP IRRIGATION USING TDR MULTI-WIRE PROBE

The adequate estimation of wetting front is fundamental to determinate the number of drippers per plant and its location below the plant canopy in drip irrigation. Measurements of wetting front dimensions are usually made by opening trenches, which is a time consuming method and sometimes imprecise. The recent scientific developments create the possibility to monitor the soil moisture content using electronics sensors. The objective of this research is to study the possibility to use TDR Multi-wire probes (Time Domain Reflectometry) with electrical impedance discontinuities in the determination of the wetting front dimensions in drip irrigation application. The experiment was divided in two parts. In the first one, it was studied the laboratory performance of two Multi-wire probe configurations and evaluated the probes reliability to monitor the water content variation in a porous media profile. The second part was conducted in a 250 L bucket and the water dynamic process was monitored during 48 h, after 5 mm of water application using a drip system. The results showed the viability to estimate the wetting front using TDR equipment coupled the Multi-wire probes with electrical impedance discontinuities.
Silane Crosslinking of High Density Polyethylene as Catalyzed by Tin and Amine Catalyst

Silane crosslinking of high density polyethylene (HDPE) is industrially used for producing crosslinked materials for pipe applications. The process involves melt-grafting of vinyl silane onto polymer chains and crosslinking of the grafted polymer with water. Without the aid of catalyst, the process takes long time to achieve a high degree of crosslinking. Dibutyltindilaurate (DBTL) is frequently used as catalyst for the crosslink reaction. However, tin compounds are toxic to human life. This study aims at investigating the feasibility of using amine compound, i.e. aminopropyltriethoxysilane (APTES), as a more environmental friendly catalyst for silane crosslinking of HDPE. Effects of amine catalyst on the progress of silane crosslink reaction and properties of crosslinked products were explored and compared to those using tin catalyst. Halloysite nanotube (HNT) was used as catalyst supporting material and also as reinforcing filler. Fourier Transform Infrared (FTIR) Spectroscopy and CHN elemental analysis confirmed the attachment of APTES on the HNT surface. For both tin and amine catalyst systems, a high degree of crosslinking (75% gel) could be reached within 24 h of curing process. DBTL showed stronger catalytic effect than the amine compound.All crosslinked products showed significant improvement in tensile strength and modulus, and slight change in thermal behaviors. The properties of crosslinked materials can be tailored by controlling time of crosslinking, type of catalyst supporting material and base polymer used in catalyst masterbatch.
Effect of Thermodynamic Melt Formation Characteristics on Liquid Phase Fluidity of Iron Ore in the Sintering Process

The liquid phase fluidity of iron ore is a vital index of fundamental sintering characteristics. In this paper, FactSage software and a visible microsintering test device were used to research the influence of the thermodynamic melt characteristics on the liquid phase fluidity under fixed CaO content conditions. The results show that the laws governing liquid phase fluidity of iron ore are significantly different with a fixed alkalinity and fixed CaO content of the sample. The liquid phase content at the sintering temperature is the most important thermodynamic melt formation characteristic affecting the liquid phase fluidity. In addition to the liquid phase content, other minerals also have a greater impact on liquid phase fluidity. Decreasing the viscosity of the liquid phase improves the liquid phase fluidity of the iron ore, and the effect of the SiO2 content of the iron ore on the mixed phase viscosity is greater than that of the Al2O3 content.

Investigation of Damping Physics and CFD Tool Validation for Simulation of Baffled Tanks at Variable Slosh Amplitude

To meet the flight control damping requirement, baffles of various configurations have been devised to increase the natural viscous damping and decrease the magnitude of the slosh forces and torques. In the design of slosh baffles, the most widely used damping equation is the one derived by Miles, which is based on the experiments of Keulegan and Carpenter. This equation has been used in predicting damping of the baffled tanks in different diameters ranging from 12 to 112 inches. The analytical expression of Miles equation is easy to use, especially in the design of complex baffle system. Previous investigations revealed that some experiments had shown good agreements with the prediction method of Miles, whereas other experiments have shown significant deviations. For example, damping from Miles equation differs from experimental measurements by as much as 100 percent over a range of tank diameters from 12 to 112 inches, oscillation amplitudes from 0.1 to 1.5 baffle widths, and baffle depths of 0.3 to 0.5 tank radius. Previously, much of this difference has been attributed to experimental scatter. A systematical study is needed to understand the damping physics of baffled tanks, to identify the difference between Miles equation and experimental measurement, and to develop new semi-empirical relations to better represent the real damping physics. The approach of this study is to use CFD technology to shed light on the damping mechanisms of a baffled tank. First, a 1-D Navier-Stokes equation representing different length scales and time scales in the baffle damping physics is developed and analyzed. A well validated CFD solver, developed at NASA MSFC, Loci-STREAM-VOF, is applied to study vorticity field around the baffle and around the fluid interface to highlight the dissipation mechanisms at different slosh amplitudes. Previous measurement data are then used to validate the CFD damping results. The study found several critical parameters controlling fluid damping from a baffle: local slosh amplitude to baffle thickness (A/t), surface liquid depth to tank radius (h/R), local slosh amplitude to baffle width (A/W); and non-dimensional slosh frequency. The simulation highlights three significant damping regimes where different mechanisms dominate. The study proves that the previously found discrepancies between Miles equation and experimental measurement are not due to the measurement scatter, but rather due to different damping mechanisms at various slosh amplitudes. The limitations on the use of Miles equation are discussed based on the flow regime.
Major variations in subtropical North Atlantic heat transport at short (5 day) timescales and their causes

Variability in the North Atlantic ocean heat transport at 26.5°N on short (5 day) timescales is identified and contrasted with different behaviour at monthly intervals using a combination of RAPID/MOCHA/WBTS measurements and the NEMO-LIM2 1/12° ocean circulation/sea ice model. Wind forcing plays the leading role in establishing the heat transport variability through the Ekman transport response of the ocean and the associated driving atmospheric conditions vary significantly with timescale. We find that at 5 day timescales the largest changes in the heat transport across 26.5°N coincide with north-westerly airflows originating over the American land mass that drive strong southward anomalies in the Ekman flow. During these events the northward heat transport reduces by 0.5–1.4 PW. In contrast, the Ekman transport response at longer monthly timescales is smaller in magnitude (up to 0.5 PW) and consistent with expected variations in the leading mode of North Atlantic atmospheric variability, the North Atlantic Oscillation. The north-westerly airflow mechanism can have a prolonged influence beyond the central 5 day timescale and on occasion can reduce the accumulated winter ocean heat transport into the North Atlantic by ? 40%.

Contrast enhancement motivates closed-syllable laxing and open-syllable tensing *

Many languages avoid tense vowels before word-final and preobstruent consonants through vowel laxing and avoid lax vowels word-finally and before prevocalic consonants through vowel tensing. This paper argues that these processes are motivated by contrast enhancement. Vowel laxing is a strategy to enhance the distinctiveness of postvocalic consonant contrasts: it applies before word-final and preobstruent consonants as a way to compensate for the absence of good perceptual cues to consonant place of articulation in these contexts. Vowel tensing is a strategy to enhance the distinctiveness of vowel contrasts. The two strategies conflict to determine vowel quality in vowel-consonant sequences and language variation results from different ways of solving this conflict in grammars with constraints on contrasts. This analysis corroborates the general claim that perceptual contrast, and in particular contrast enhancement, plays a role in shaping phonotactic restrictions (e.g. Flemming 2002).
Psychosocial Stress among Bankers Due To Long Working Hours: Case Study of University of Cape Coast Banks.

The study aimed at investigating the impact of psychosocial stress among bankers in the University of Cape Coast in the Central Region of Ghana. The study focused specifically on the following: examine the psychosocial stress on bankers due to long working hours, find out the strategies that bankers could adopt to reduce stress associated with long working hours and lastly assess the impact of psychosocial stress on the health of bankers. The convenience sampling technique was used to select 76 participants for the study. The results of the study indicated that on the psychosocial stress associated with long working hours among bankers, bankers generally reported that they were aware of the psychosocial stress based on the statement outlined on the questionnaire. Health-wise, to a great extent that psychosocial stress associated with long working hours do not affect the health of bankers in the University of Cape Coast. Management commitment to employee-related issues such as paying attention to workload conflict and the introduction of proper stress management training programmes were perceived as significant steps which if embraced, were identified as major contributory factors that could contribute to the alleviation of psychosocial stress among staff.
Experimental Pore-Scale Study of a Novel Functionalized Iron-Carbon Nanohybrid for Enhanced Oil Recovery (EOR)

Nanofluid flooding, as a new technique to enhance oil recovery, has recently aroused much attention. The current study considers the performance of a novel iron-carbon nanohybrid to EOR. Carbon nanoparticles was synthesized via the hydrothermal method with citric acid and hybridize with iron (Fe3O4). The investigated nanohybrid is characterized by its rheological properties (viscosity), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) analysis. The efficiency of the synthetized nanoparticle in displacing heavy oil is initially assessed using an oil–wet glass micromodel at ambient conditions. Nanofluid samples with various concentrations (0.05 wt % and 0.5 wt %) dispersed in a water base fluid with varied salinities were first prepared. The prepared nanofluids provide high stability with no additive such as polymer or surfactant. Before displacement experiments were run, to achieve a better understanding of fluid–fluid and grain–fluid interactions in porous media, a series of sub-pore scale tests—including interfacial tension (IFT), contact angle, and zeta potential—were conducted. Nanofluid flooding results show that the nanofluid with the medium base fluid salinity and highest nanoparticle concertation provides the highest oil recovery. However, it is observed that increasing the nanofluid concentration from 0.05% to 0.5% provided only three percent more oil. In contrast, the lowest oil recovery resulted from low salinity water flooding. It was also observed that the measured IFT value between nanofluids and crude oil is a function of nanofluid concentration and base fluid salinities, i.e., the IFT values decrease with the increase of nanofluid concentration and base fluid salinity reduction. However, the base fluid salinity enhancement leads to wettability alteration towards more water-wetness. The main mechanisms responsible for oil recovery enhancement during nanofluid flooding is mainly attributed to wettability alteration toward water-wetness and micro-dispersion formation. However, the interfacial tension (IFT) reduction using the iron-carbon nanohybrid is also observed but the reduction is not significant.
Trading Behavior of Foreign Vis a Vis Local Investors in The Indonesian Stock Market

This paper studies the behavior of foreign, local investors and total market in a stock trading. The analysis is focused on their implementation of positive feedback strategy, the existence of mean reverting process and their sensitivity toward expected capital gain and losses. The result reveals that both of these two investors apply the positive feedback strategy, at a different degree. The investment horizon of the foreign investors is shorter than the local investors. There is a mean reverting pattern in the price volatilities. The convergence period for local investor is 2.4. The market needs 1.8 month. No convergence period for foreign investors. The local investors and total market are neutral toward expected gain and losses. The foreign investors are more sensitive to capital loss. Previous price and volume changes have a leverage effect to the current demand of foreign investors. The local investors are affected by changes in price only.
Bio-economic modelling of the influence of family planning, land consolidation and soil erosion on farm production and food security in Rwanda

Rwandan agriculture is not able to meet its population’s food needs from its own production, which results in food insecurity. Land degradation is a serious problem which contributes to a low and declining agricultural productivity and consequently to food insecurity. The objective of this paper is to develop a bio-economic model capable of analysing the impacts of soil erosion, family planning and land consolidation policies on food security in Rwanda. The results of the bio-economic model show that a higher availability of good farm land would increase the farm income. Additionally, preserving soils against erosion and reducing risk would allow for releasing more marginal land which would increase food production for home consumption and for the market. Increasing the opportunities for off-farm employment can also increase farm household income. The outcomes of the model support the Rwanda policy on family planning, while the policy on land consolidation is not endorsed. Key words: Rwanda, land degradation, food security, bioeconomic model, family planning policy,
Biochemical and Molecular Actions of Nutrients Dietary Fatty Acids Regulate Acyl-CoA : Cholesterol Acyltransferase and Cytosolic Cholesteryl Ester Hydrolase in Hamsters 1 , 2

To investigate the effects of dietary fatty acids on acyl-CoA:cholesterol acyltransferase (ACAT) and cytosolic cholesteryl ester hydrolase (cCEH), male Syrian hamsters (F1B hybrid) were fed a modified version of the NIH-07 open formula, cereal-based rodent diet enriched with one of the following 4 dietary fatty acids: palmitic acid (16:0), trans fatty acids (18:1t), oleic acid (18:1c), or linoleic acid (18:2). Hamsters fed 16:0 and 18:1t had significantly higher plasma non-HDL cholesterol concentrations compared with those fed 18:1c and 18:2. However, differences in plasma apolipoprotein (apo)B100 concentration, hepatic cCEH mRNA abundance, and hepatic ACAT activity between 16:0and 18:1t-fed hamsters suggest that the hypercholesterolemic effects are achieved by different mechanisms. Specifically, an increase in ACAT activity by 16:0 may induce enrichment of cholesteryl esters in apoB100-containing particles, whereas 18:1t may increase the number of the particles. Hepatic cholesteryl esters accumulated in the 18:1cand 18:2-fed groups with no differences in hepatic ACAT activity and cCEH mRNA abundance among hamsters fed unsaturated fatty acids (i.e., 18:1t, 18:1c, and 18:2). Considering the lack of change in free cholesterol concentration and increased cholesteryl esters in the liver, the hypocholesterolemic effect of 18:1c and 18:2 compared with 18:1t may be attributed to decreased production of apoB100-containing particles. ACAT-1 was expressed in all the tissues examined; in contrast, ACAT-2 was highly expressed in the liver and small intestine. Hepatic ACAT activity was disproportionate to the levels of ACAT-1 and ACAT-2 mRNA and protein, indicating post-transcriptional regulation of ACAT by dietary fatty acids. The data suggest that cholesterolemic effects of individual dietary fatty acids can be achieved through their independent modulation of pathways regulating assembly and secretion of apoB100-containing particles.
