Reaction kinetics of lactic acid fermentation from bitter cassava (Manihot glaziovii) starch by Lactobacillus casei

One of the utilizations of bitter cassava is modified cassava flour (Mocaf) production using the fermentation process by Lactobacillus casei . The Mocaf has potential as the future of food security products. It has a characteristic property similar to wheat flour. Lactic acid was also produced as a by‐product during fermentation. After 40 h of fermentation, the proximate composition content of Mocaf was lactic acid content of 0.000928 g/L, hydrogen cyanide levels of 0.02 ppm, starch content of 59.13%, amylose content of 12.98% and amylopectin content of 46.15%. In the scaling‐up process from a laboratory scale to a pilot and industrial scale, modeling is needed. There are five equation models used to describe the kinetic reactions of lactic acid from bitter cassava starch: Monod, Moser, Powell, Blackman, and Product Inhibitor. Each parameter was being searched by a fitting curve using sigmaplot 12.0. The best result in terms of the highest R2 (0.65913) was obtained in the Powell equation with the value of µmax of 1.668/h, Ks of 123.4 g/L, and maintenance rate (m) of 4.672. The kinetic data obtained can be used to design biochemical reactors for industrial scale Mocaf flour production.
The exploration of artificial intelligence application in fashion trend forecasting

Fashion trends today are changing much faster than ever before. Timely and reliable trend forecasting is, therefore, critical in the fashion industry. Traditional fashion forecasting requires professionals to abstract image-based information across design collections and time intervals from around the world, which is extremely time-consuming and labor intensive. Considering the financial cost associated with manual labeling and the accuracy of classifications based upon human subjective judgment, this explorative study proposes a data-driven quantitative abstracting approach using an artificial intelligence (A.I.) algorithm. Firstly, an A.I. model was trained to be familiar with fashion images from a large-scale dataset under different scenarios such as online stores and street snapshots; secondly, the model could detect garments and classify clothing attributes such as fabric textures, garment style, and design details from runway photos and videos; thirdly, the model could summarize fashion trends from the attributes it developed. The adoption of an A.I. algorithm proved to be an objective and systematic computerized method of interpreting fashion dynamics in a more efficient, accurate, sustainable, and cost-effective way.
Cost-benefit analysis approach to risk assessment of natural radioactivity in powdered and liquid milk products consumed in Nigeria

ABSTRACT This article presents important facts on food safety in milk consumed in Nigeria that are in agreement with NAFDAC plan regarding the safety of food in Nigeria. The radioactivity con-centrations in powdered and liquid milk consumed in Nigeria were investigated using a sodium iodide (NaI(Tl)) detector. The activity concentrations of the three naturally occurring radionuclides, 226Ra, 232Th, and 40K, were measured in 10 brands of powdered milk and 11 brands of liquid milk. The results show that the mean activity concentration of 40K in the powder and liquid samples was 468.0 ± 72.7 Bq kg−1and 317.6 ± 58.5 Bq kg−1, respectively. The mean values for 226Ra for powdered and liquid milk were 19.2 ± 7.2 Bq kg−1 and 16.6 ± 6.3 Bq kg−1, respectively, while for 232Th it is 12.1 ± 4.8 Bq kg−1 and 10.6 ± 4.3 Bq kg−1, respectively. The average value of 40K in the powdered milk was found to be slightly above the standard value set by UNSCEAR for foodstuffs. The values of the calculated hazard indices and the radium equivalent of all milk samples were within the permissible limit set by UNSCEAR and other international regulatory bodies. However, the consumption of powdered and liquid milk by infants and children at the rate of 14 to 15 kg/year, from this analysis may result in radiation doses to vital organs above standard values. It is recommended that the amount of powdered milk consumed per year by infants and children should not exceed 7 and 11 kg/year while for liquid milk it should not exceed 8 and 13 kg/year, respectively. The cost-benefit analysis shows a low collective effective dose equivalent with a mean radiological index ratio of 1:30,839 for infants, 1:50,909 for children, and 1:247,145 for adults. The computed values of the total cost of the health detriment of consuming these examined milk products revealed that the child age group has the highest cost health detriment per capita dose, with an estimated total cost of health detriment of US$17.256 million, followed by adults, with an estimated cost implication of US$11.864 million; infants have the least, with an estimated cost implication of US$10.192 million. The overall results show that the powdered and liquid milk consumed in Nigeria are radiologically safe and may not cause any immediate radiation health hazard to consumers of the examined milk brands, while optimizing radiation protection using cost-benefit analysis is recommended.
Studying Medical Errors among Hospital-Staff at Saudi Health Providers

The electronic properties of perovskite systems La(subscript 1-x)Sr(subscript x)FeO3 (x = 0, 0.67, 0.75, 1) for periodic structures and x = 0.5 for clusters) were investigated basing on density functional theory (DFT) using Dmol3 code. Our results show that LaFeO3 is antiferromagnetic insulator and SrFeO3 expresses itself as conducting material with dominated antiferomagnetic phase. The calculations also confirmed an existence of iron ions with different valences. Especially, for La0.33Sr0.67FeO3 iron ions may have valences≧+5. Investigation on polarization of clustering La0.5Sr0.5FeO3 structure reveals that this system is spontaneously strongly polarized with the polarization vector magnitude□10^2 times larger than that of the well-known ferroelectric BaTiO3.

The contribution of managerial ability on customer satisfaction: an empirical investigation

ABSTRACT The study empirically examines the effects of managerial ability on customer satisfaction, as well as the role of firm-level and industry-level moderators on the relationship. The effect of customer satisfaction on firm value is also investigated. Managerial ability is assessed as the residual remaining after accounting for the effects of seven key financial variables, while customer satisfaction is derived from the ACSI panel data. The results demonstrate that managerial ability positively affects ex-post customer satisfaction, indicating that more capable managers are better able to satisfy their customers. In turn, customer satisfaction directly influences firm value, as measured by Tobin’s q. In terms of moderators, non-service firms more strongly regulate the managerial ability-customer satisfaction link; advertising expenditure and competitive intensity have insignificant roles to play.
Changing migration rates in England and Wales over a 40‐year period: Is mobility declining?

Research using data for the United States has pointed towards a long-term pattern of falling migration rates. Similar research in England and Wales has also found declining migration rates when observing all migrants. Using the Office for National Statistics Longitudinal Study (ONS LS), we study the patterns of migration observed over 10-year periods for persons in 10-year birth cohorts over each intercensal period from 1971 – 1981 through to 2001 – 2011. When the sample population is considered as a whole, the results from the LS are consistent with earlier findings: There has been a decade-on-decade decline in the migration rate as observed in longitudinal data. When disaggregated by cohort, it is apparent that this decline is not always observed for young adults, but it is consis-tently observed for those in their 30s and older, for whom each successive cohort has a lower migration rate than the previous one and also for whom there is a steady within-cohort decline in the migration rate over time. This is observed at both short and longer distances of move. Alternative results from successive censuses looking at migration observed for single years do not appear to confirm this decline in migration, although data collection and processing issues may be part of the explanation for this finding, and it is also the case that these data may be more subject to cyclical effects.
HAEMATOLOGICAL RESPONSES OF PENGGING DUCKS FED MORINGA (MORINGA OLEIFERA) LEAF MEAL AS FEED ADDITIVES

Pengging ducks are one breed of Indonesia’s local duck has superior potential. This study was designed to evaluate the hematological parameters of Pengging ducks fed Moringa leaf meal as a feed additive. The data were obtained from a total of 80 female Pengging ducks of 35 weeks old were assigned into a completely randomized design and each experimental unit consisted of 4 replications. The treatment group consisted of basal fed without added Moringa leaf meal (control), basal fed added with 2.5, 5, 7.5, and 10% Moringa leaf meal. Data analyzed using one-way ANOVA. The results showed that the addition of Moringa leaf meal gave same effect (P>0.05) on the number of erythrocytes, hemoglobin, hematocrit, mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH). However, the mean corpuscular hemoglobin concentration (MCHC) increased (P<0,05) to 15.91% at 5% moringa leaf meal. The number of leukocytes was lower (P<0.05) by 42.01% at 7.5% moringa leaf meal. Leukocyte differentials, the ratio of H:L, and trombocytes did not significant difference (P>0.05) between treatments. In conclusion, the Moringa leaf meal as a feed additive did not change the hematological parameters and could be increasing the health status of layer Pengging ducks.

How to foster employee satisfaction by means of coaching, motivation, emotional salary and social media skills in the agri-food value chain

Most employee satisfaction studies do not consider the current digital transformation of the social world. The aim of this research is to provide insight into employee satisfaction in agribusiness by means of coaching, motivation, emotional salary and social media with a value chain methodology. The model is tested empirically by analysing a survey data set of 381 observations in Spanish agribusiness firms of the agri-food value chain. The results show flexible remunerations of emotional salary are determinants of employee satisfaction. Additionally, motivation is relevant in the production within commercialisation link and coaching in the production within transformation link. Whole-of-chain employees showed the greatest satisfaction with the use of social media in personnel management. Findings also confirmed that employees will stay when a job is satisfying. This study contributes to the literature by investigating the effect of current social and digital business skills on employee satisfaction in the agri-food value chain.
Prediction of fiber breakage and matrix cracking in polymeric composites under low-cycle fatigue regimes by fuzzy and wavelet clustering of acoustic emission signals

One of methods for detecting cracks and estimating their growth in materials such as composites is the acoustic emission technique. The detection of damages, cracks and their growth in industrial composite structures, under static and dynamic loads, has a significant importance, in order to prevent any damages and increase the reliability. Therefore, achieving required technical knowledge in this field, can be helpful in repairing and the maintenance of the part in industries. The prediction of the damage in polymeric composites under static loads has been already investigated by researchers; however, under cyclic loadings, researches about this behavior are still rare. In this study, by acoustic emission sensors and analyzing experimental data, the damage, including matrix cracking, the fiber breakage and other damages (debonding, fiber pull-out and delamination) during dynamic loading was investigated. At the first stage, standard specimens were made by the pure resin epoxy and the pure carbon fiber, subjected to monotonic tensile loading and then, the frequency of the failure was extracted. Then, composite specimens were loaded in the low-cycle fatigue regime. Mechanical test results and acoustic emission data were analyzed by fuzzy C-Means and wavelet transform methods and then compared to each other to find the percentage of failures in first, mid- and last cycles by the differentiation of failure types. Results clearly indicated that the acoustic emission approach is useful and an effective tool for identifying and detecting damages in polymeric composites.
Welfare Consequences of Sustainable Finance

We model the welfare consequences of mandates that restrict investors to hold firms with net-zero carbon emissions. To qualify for these mandates, value-maximizing firms have to accumulate decarbonization capital. Qualification lowers a firm's required return by its decarbonization investments divided by Tobin's q, that is, the greenium or the dividend yield shareholders forgo to address the global-warming externality. The welfare-maximizing mandate approximates the first-best solution, yielding welfare gains compared to laissez-faire by mitigating the weather disaster risks resulting from carbon emissions. Our model generates optimal transition paths for decarbonization that we use to evaluate proposed net-zero targets.
Upper Thermal Tolerance Indicated by CTmax Fails to Predict Migration Strategy and Timing, Growth, and Predation Vulnerability in Juvenile Brown Trout (Salmo trutta)

Partial migration is common in a variety of taxa and has important ecological and evolutionary implications, yet the underlying factors that lead to different migratory strategies are not clearly understood. Given the importance of temperature in serving as a cue for migration, along with its role in regulating metabolism, growth, reproduction, and survival, we examined how intraspecific variation in critical thermal maximum (CTmax) values influenced migratory strategy (residency vs. migration), timing of migration, growth, and predation vulnerability in a wild population of partially anadromous juvenile brown trout (Salmo trutta). Using passive integrated transponder telemetry and mark-recapture techniques, we identified individuals that out-migrated to sea, assumed residency, and were predated by cormorants several months later. Acute thermal stress induced by conducting CTmax trials did not affect the final fate of assayed fish compared with controls. We found that mass and body condition predicted CTmax and migration timing, but CTmax failed to predict migratory strategy or timing, growth (of resident fish), or predation vulnerability. Although there may be links between mass, thermal tolerance, and migration strategy, the relationship between CTmax and migration remains unclear. The role of upper thermal tolerance in influencing life-history strategies should not be neglected, however, as alternative indicators of thermal tolerance could be further explored. The high degree of variation in CTmax estimates warrants additional investigation of how increasingly prevalent high-temperature events might drive selection toward thermally tolerant extremes, which is particularly relevant in a rapidly warming world.
Observed Global Increases in Tropical Cyclone‐Induced Ocean Cooling and Primary Production

Tropical cyclones provide an important source of ocean mixing, bringing cold, nutrient‐rich water to the surface and triggering phytoplankton blooms. Here, we show significant increases in global tropical cyclone‐induced sea surface temperature cooling and surface chlorophyll‐a concentration of 0.05°C and 3.7 × 10−3 mg m−3 per decade over the past 20–35 years. The trends have been driven primarily by an increase in the intensity of strong tropical cyclones. The increase in chlorophyll‐a concentration has been, on average, 1.6% per decade in oligotrophic areas during the tropical cyclone season, in contrast to a decrease of 0.1% per decade during the other months. This tropical cyclone‐induced increase has partially mitigated the overall decline in primary production under climate change.
Impact of Wettability on Residual Oil Saturation and Capillary Desaturation Curves

ABSTRACT In this paper, we supplement capillary desaturation data in the literature with additional wetting systems. The study is performed on Berea sandstone rock samples prepared with different wetting conditions. The rock wettability was characterized with spontaneous imbibition. Residual oil saturations as a function of capillary and Bond number are measured using flooding and centrifuge techniques, respectively, for a wide range of capillary and Bond numbers. We find a strong interrelation between wettability, residual oil saturation, and critical capillary and Bond numbers. As the system becomes less water-wet the residual oil saturation decreases and the critical capillary and Bond numbers increase. We find that the critical capillary or Bond number for strongly water-wet rock is , which is in agreement with data reported in literature. However, for less water-wet rock, the critical capillary or Bond number is higher by at least one order of magnitude. The data presented in this paper indicate that reservoir wettability may significantly impact the design of enhanced oil recovery processes.

Background There is limited data on the clinical characteristics and predictors of mortality of coronavirus disease-2019 (COVID-19) in North West Ohio. We performed a retrospective review of patients hospitalized with COVID-19 in the ProMedica Health System in Northwest Ohio from March 25 to June 16, 2020. The study aims to identify epidemiological, clinical characteristics, and predictors of Mortality of COVID-19 patients in Northwest Ohio. Methods This study was conducted on 217 COVID-19 patients admitted to ProMedica Health System Hospitals in Northwest Ohio from March 25 to June 16, 2020. We collected data, including clinical signs, symptoms, and outcomes of the COVID-19 patients. We compared clinical signs and symptoms along with comorbidities of survivors and non-survivors. Results Of the 217 patients included in the study, the mean age of the population was 63.13 (SD 17.8), of which 194 (89.4%, mean age 61.7 years) survived while 23 (10.6%, mean age 74.6 years) died. Among them, 53% were females and 47% male. Common presenting symptoms were chest pain (91.71%), shortness of breath (79.7%), cough (71%), and fever (64%). Mortality was associated with age greater than 63 (p-value 0.0052) and hypertension (p-value: 0.0058) with marginal significance with gender (p-value: 0.0642), chest pain (p-value: 0.0944), and history of cancer (p-value: 0.0944). Conclusions Advanced age and hypertension (HTN) are independent predictors for increased mortality. History of cancer and chest pain are associated with increased mortality with marginal significance. Awareness among physicians about predictors of mortality is essential in dealing with COVID-19 patients. It is essential to educate the public about preventative strategies such as wearing masks to decrease mortality and morbidity from this pandemic.
The infection of ectoparasitic protozoa on farmed Nile tilapia (Oreochromis niloticus) at three reservoirs in Central Java, Indonesia

Abstract. Kolia WSK, Sunarto, Widiyani T. 2021. The infection of ectoparasitic protozoa on farmed Nile tilapia (Oreochromis niloticus) at three reservoirs in Central Java, Indonesia. Biodiversitas 22: 1975-1980. There is an expansion of fish culture in Indonesia, but there is a dearth of information on the parasitic infecting cultured fish. This study was conducted to investigate the occurrence of ectoparasitic protozoans on farmed Nile tilapia (Oreochromis niloticus) at three reservoirs (i.e., Cengklik, Mulur, and Gajah Mungkur) in Central Java, Indonesia, and to determine the prevalence, mean abundance, and mean intensity of such parasites. A total of 189 samples were collected from different cages. The sex of the fishes was determined and their lengths and weights were measured. The gills, fins, and skin were examined for ectoparasitic protozoa using a light microscope. Among the examined fishes, 146 samples were infected at the rate of 77.2 %. Mulur reservoir had the highest prevalence rate with 90.4%, followed by Cengklik and Gajah Mungkur with 82.5 % and, 58.7%, respectively. We found female fishes were more susceptible to the infection than males. Seven parasite species were identified, namely: Tetrahymena corlissi, Apiosoma spp. , Trichodina spp. , Cryptobia spp. , Chilodonella spp. , Ambiphrya spp. , and Ichthyophthirius multifiliis. The protozoan parasite Trichodina spp. recorded the highest prevalence, mean intensity, and mean abundance among all the other protozoan species at the three reservoirs. The results provided a significant difference at (p<0.01) in the total number of parasites among the reservoirs. Despite the parasite infection, the physical and chemical parameters of the water of the three reservoirs were within the recommended range for the culture of Nile tilapia under the cage systems.
