Deep Learning Model Based on ResNet-50 for Beef Quality Classification
Food quality measurement is one of the most essential topics in agriculture and industrial fields. To classify healthy food using computer visual inspection, a new architecture was proposed to classify beef images to specify the rancid and healthy ones. In traditional measurements, the specialists are not able to classify such images, due to the huge number of beef images required to build a deep learning model. In the present study, different images of beef including healthy and rancid cases were collected according to the analysis done by the Laboratory of Food Technology, Faculty of Agriculture, Kafrelsheikh University in January of 2020. The texture analysis of the beef surface of the enrolled images makes it difficult to distinguish between the rancid and healthy images. Moreover, a deep learning approach based on ResNet-50 was presented as a promising classifier to grade and classify the beef images. In this work, a limited number of images were used to present the research problem of image resource limitation; eight healthy images and ten rancid beef images. This number of images is not sufficient to be retrained using deep learning approaches. Thus, Generative Adversarial Network (GAN) was proposed to augment the enrolled images to produce one hundred eighty images. The results obtained based on ResNet-50 classification achieve accuracy of 96.03%, 91.67%, and 88.89% in the training, testing, and validation phases, respectively. Furthermore, a comparison of the current model (ResNet-50) with the classical and deep learning architecture is made to demonstrate the efficiency of ResNet-50, in image classification
Dramapedagoške tehnike u razvijanju govora u nastavi njemačkog kao stranog jezika
Das Thema dieser Arbeit sind dramapädagogische Techniken zur Förderung des Sprechens im Deutschunterricht als Fremdsprache. Die Arbeit besteht aus zwei Haupteilen, dem theoretischen und dem empirischen Teil. Im theoretischen Teil bespricht man die Grundbedeutung „Dramapädagogik“ und ihre historische Entwicklung, führt die Versuche ihrer Bedeutungsbestimmung und ihre Verbindung mit Theater auf und gibt konkrete Beschreibungen von dramapädagogischen Aufgaben zur „Aufwärmung“ und dramapädagogische Techniken im Unterricht. Der empirische Teil beginnt mit einer Einleitung in die Aktionsforschung und ihren Zweck. Darauffolgend wird die Methodologie der Aktionsforschung vorgestellt, ihre Resultate und die Diskussion über die gewonnenen Daten. Das Hauptziel der Aktionsforschung war die Förderung des Sprechens bei Schülern auf Deutsch durch die Anwendung von dramapädagogischen Techniken. Im Einklang mit den Merkmalen und Charakteristiken der Aktionsforschungen wurde eine Unterrichtstunde entworfen, in der Länge von 45 Minuten, gedacht für die zweite Klasse einer Mittelschule. Die Resultate der Aktionsforschung zeigen, dass die dramapädagogischen Aktivitäten den Schülern interessant sind und ihre Motivation zum aktiven Sprechen im Fremdsprachenunterricht fördern. Die Schüler kamen in Situationen, die nicht nur ihre geistig- sprachlichen Fähigkeiten erfordern, sondern auch die Körpersprache, gemeinsame Aushandlung von Bedeutung und emotionales Verständnis. Durch die Anwendung und Realisierung des dramapädagogischen Zugangs wird das Erlernen einer Fremdsprache auf ein höheres Niveau gebracht, weil es unter anderem die Phantasie, Kreativität, Spontanität und Originalität der Schüler weckt. Somit kann man darauf schließen, dass der dramapädagogische Zugang viel mehr Vorteile aufweist, als der herkömmliche Unterricht, der auf Inhalt und Fakten basiert.Tema ovog rada su dramapedagoške tehnike u procesu razvoja govora u nastavi njemačkog kao stranog jezika. Rad je podijeljen u dvije osnovne cjeline, teorijski i empirijski dio. U teorijskom dijelu rada polazi se od temeljnog pojma „Dramapädagogik“, povijesnog razvoja ove metode, pokušaja definiranja pojma, pojašnjenja temelja dramapedagogije te njezinih poveznica s kazalištem i nastavom stranog jezika. Navedeni dio završava opisom konkretnih dramapedagoških vježbi za „zagrijavanje“ i dramapedagoških tehnika u nastavi. U empirijskom se dijelu daje uvod u akcijsko istraživanje i njegovu svrhu, daje opis metodologije akcijskog istraživanja, prikazuju se rezultati i diskutira o dobivenim podatcima. Osnovni je cilj istraživanja bio unaprijediti i potaknuti razvoj govora učenika na njemačkom jeziku korištenjem dramapedagoških tehnika. U skladu s obilježjima i karakteristikama akcijskog istraživanja, osmišljen je jedan nastavni sat njemačkog jezika kroz dramapedagoški pristup, u trajanju od 45 minuta. Navedeni je sat ostvaren s učenicima drugog razreda srednje škole. Rezultati istraživanja pokazali su kako su dramapedagoške aktivnosti učenicima zabavne te da promiču njihovu interakciju i motivaciju za aktivnim sudjelovanjem i govorom u nastavi stranog jezika. Učenici su se našli u situacijama koje nisu zahtijevale primjenu samo njihovih intelektualnih vještina, već i govor tijela, zajedničko konstruiranje značenja te emocionalno razumijevanje. Ostvarivanjem dramapedagoškog pristupa u nastavi učenje stranog jezika podiže se na višu razinu jer se, između ostaloga, razvija i učenikova mašta, kreativnost, spontanost i originalnost. Prema tome može se zaključiti kako dramapedagoški pristup nastavi ima puno više prednosti u odnosu na konvencionalnu, tradicionalnu nastavu koja je usmjerena samo na sadržaj i činjenično znanje
Recurrent right sublingual ranula, concomitant with ipsilateral submandibular salivary gland aplasia
AbstractINTRODUCTIONOral ranula is a retention cyst that arises from the salivary gland with recurrence rate of up to 25% after complete excision of ranula and up to 2% in case of complete excision of ranula and sublingual gland.Major salivary gland aplasia is a rare finding that is usually associated with other developmental anomalies.PRESENTATION OF CASEWe report a 15-year-old female patient presented with recurrent intraoral cystic swelling that was documented to be sublingual ranula. CT scan revealed also the absence of right submandibular salivary gland with persistence of its Whartons duct. This combination has never been reported previously.DISCUSSIONThe combination of recurrent sublingual ranula associated with aplasia of ipsilateral submandibular salivary gland and persistence of Whartons duct has never been reported before in the literature, a finding that may provide the base for future research.CONCLUSIONFurther research may prove similar associations between oral ranula and salivary gland aplasia, which may have clinical implications on diagnostic and management plan decisions

Bacterial community structure in anaerobic digesters of a full scale municipal wastewater treatment plant - Case study of dubai, united arab emirates
© 2019, International Centre for Sustainable Development of Energy, Water and Environment Systems SDEWES. All rights reserved. A highly complex microbial community involved in anaerobic sludge digesters plays vital roles in sludge treatment. The data on microbial ecology is important to accomplish efficient operation of the anaerobic digesters. This study is aimed at monitoring the bacterial community of three full-scale anaerobic digesters of a full-scale municipal wastewater treatment Plant in Dubai, United Arab Emirates. Fluorescent in-situ hybridization technique was applied to identify the bacterial groups and quantitative polymerase chain reaction to compare the richness of bacterial and archaeal domain. Results of the fluorescent in-situ hybridization technique analysis showed that the phylum Proteobacteria was most abundant followed by cytophage-Flavobacterium group of Bacteroides, Firmicutes and Actinobacteria. Among proteobacterial subclass Delta- and Alpha- were dominating than Gamma- and Beta-proteobacteria. The genus Desulfobacter and Desulfobacterium were the dominant groups hybridizing 70-76% of total 4\u27, 6\u27- diamidino - 2 phenylindole stained cells. The quantitative polymerase chain reaction results showed that Bacterial domain was dominating in all three digesters compared to the archaeal domain
Cerebrospinal Fluid Metals and the Association with Cerebral Small Vessel Disease
BACKGROUND: Brain metal homeostasis is essential for brain health, and deregulation can result in oxidative stress on the brain parenchyma. OBJECTIVE: Our objective in this study was to focus on two hemorrhagic MRI manifestations of small vessel disease [cerebral microbleeds (CMBs) and cortical superficial siderosis (cSS)] and associations with cerebrospinal fluid (CSF) iron levels. In addition, we aimed to analyze CSF biomarkers for dementia and associations with CSF metal levels. METHODS: This is a cross-sectional study of 196 patients who underwent memory clinic investigation, including brain MRI. CSF was collected and analyzed for metals, amyloid-β (Aβ) 42, total tau (T-tau), and phosphorylated tau (P-tau), and CSF/serum albumin ratios. Statistical analyses were performed using generalized linear models. RESULTS: No significant difference was found between CSF metal levels across diagnostic groups. Higher iron and copper levels were associated with higher CSF levels of Aβ42, T-tau, P-tau, and CSF/serum albumin ratios (p < 0.05). Zinc was associated with higher CSF/serum albumin ratios. There was no significant association between CMBs or cSS and CSF iron levels. An increase in CSF iron with the number of CMBs was seen in APOEɛ4 carriers. CONCLUSION: CSF iron levels are elevated with cerebral microbleeds in APOEɛ4 carriers, with no other association seen with hemorrhagic markers of small vessel disease. The association of elevated CSF iron and copper with tau could represent findings of increased neurodegeneration in these patients
System for Contributing and Discovering Derived Mission and Science Data
A system was developed to provide a new mechanism for members of the mission community to create and contribute new science data to the rest of the community. Mission tools have allowed members of the mission community to share first order data (data that is created by the mission s process in command and control of the spacecraft or the data that is captured by the craft itself, like images, science results, etc.). However, second and higher order data (data that is created after the fact by scientists and other members of the mission) was previously not widely disseminated, nor did it make its way into the mission planning process
The Impact of Spatial Incongruence on an Auditory-Visual Illusion
The sound-induced flash illusion is an auditory-visual illusion--when a single flash is presented along with two or more beeps, observers report seeing two or more flashes. Previous research has shown that the illusion gradually disappears as the temporal delay between auditory and visual stimuli increases, suggesting that the illusion is consistent with existing temporal rules of neural activation in the superior colliculus to multisensory stimuli. However little is known about the effect of spatial incongruence, and whether the illusion follows the corresponding spatial rule. If the illusion occurs less strongly when auditory and visual stimuli are separated, then integrative processes supporting the illusion must be strongly dependant on spatial congruence. In this case, the illusion would be consistent with both the spatial and temporal rules describing response properties of multisensory neurons in the superior colliculus.status: publishe
Sex and Socioeconomic Differentials in Child Health in Rural Bangladesh: Findings from a Baseline Survey for Evaluating Integrated Management of Childhood Illness
This paper reports on a population-based sample survey of 2,289 children aged less than five years (under-five children) conducted in 2000 as a baseline for the Bangladesh component of the Multi-country Evaluation (MCE) of the Integrated Management of Childhood Illness strategy. Of interest were rates and differentials by sex and socioeconomic status for three aspects of child health in rural Bangladesh: morbidity and hospitalizations, including severity of illness; care-seeking for childhood illness; and home-care for illness. The survey was carried out among a population of about 380,000 in Matlab upazila (subdistrict). Generic MCE Household Survey tools were adapted, translated, and pretested. Trained interviewers conducted the survey in the study areas. In total, 2,289 under-five children were included in the survey. Results showed a very high prevalence of illness among Bangladeshi children, with over two-thirds reported to have had at least one illness during the two weeks preceding the survey. Most sick children in this population had multiple symptoms, suggesting that the use of the IMCI clinical guidelines will lead to improved quality of care. Contrary to expectations, there were no significant differences in the prevalence of illness either by sex or by socioeconomic status. About one-third of the children with a reported illness did not receive any care outside the home. Of those for whom outside care was sought, 42% were taken to a village doctor. Only 8% were taken to an appropriate provider, i.e. a health facility, a hospital, a doctor, a paramedic, or a community-based health worker. Poorer children than less-poor children were less likely to be taken to an appropriate healthcare provider. The findings indicated that children with severe illness in the least poor households were three times more likely to seek care from a trained provider than children in the poorest households. Any evidence of gender inequities in child healthcare, either in terms of prevalence of illness or care-seeking patterns, was not found. Care-seeking patterns were associated with the perceived severity of illness, the presence of danger signs, and the duration and number of symptoms. The results highlight the challenges that will need to be addressed as IMCI is implemented in health facilities and extended to address key family and community practices, including extremely low rates of use of the formal health sector for the management of sick children. Child health planners and researchers must find ways to address the apparent population preference for untrained and traditional providers which is determined by various factors, including the actual and perceived quality of care, and the differentials in care-seeking practices that discriminate against the poorest households
Worldwide evaluations of quinoa: preliminary results from post International Year of Quinoa FAO projects in nine countries
Chenopodium quinoa Willd, a high quality grain crop, is resistant to abiotic stresses (drought, cold, and salt) and offers an optimal source of protein. Quinoa represents a symbol of crop genetic diversity across the Andean region. In recent years, this crop has undergone a major expansion outside its countries of origin. The activities carried out within the framework of the International Year of Quinoa provided a great contribution to raise awareness on the multiple benefits of quinoa as well as to its wider cultivation at the global level. FAO is actively involved in promoting and evaluating the cultivation of quinoa in 26 countries outside the Andean region with the aim to strengthen food and nutrition security. The main goal of this research is to evaluate the adaptability of selected quinoa genotypes under different environments outside the Andean region. This paper presents the preliminary results from nine countries. Field evaluations were conducted during 2013/2014 and 2014/2015 in Asia (Kyrgyzstan and Tajikistan), and the Near East and North African countries (Algeria, Egypt, Iraq, Iran, Lebanon, Mauritania, and Yemen). In each country, the trials were carried out in different locations that globally represent the diversity of 19 agrarian systems under different agro-ecological conditions. Twenty-one genotypes of quinoa were tested using the same experimental protocol in all locations consisting in a randomized complete block design (RCBD) with three replicates. Some genotypes showed higher yields and the Q18 and Q12 landraces displayed greater adaptation than others to new environmental conditions. The Q21 and Q26 landraces were evaluated with stable and satisfactory levels of yield (>1 t.ha−1) in each of the different trial sites. This production stability is of considerable importance especially under climate change uncertainty. While these results suggest that this Andean crop is able to grow in many different environments, social, and cultural considerations remain crucial regarding its possible introduction as a staple food in new cropping systems around the world
