Authors: Mahgoub Osman , Al-Mahrouqi Hafidh , Al-Lawati Sadeq , Al-Muqbali Rabea
Published: February 2020

A study was carried out to evaluate the nutritional value of spirulina (Arthrospira platensis) to determine its potential use for feeding livestock in Oman. Spirulina was grown in wooden cubicles and harvested after 10 days. One batch of spirulina was dried by centrifugation (CS) and the other was dried in an oven without centrifugation (NCS). Samples were analyzed for dry matter (DM) and proximate chemical components. An in vitro assessment was carried out to measure gas production and in vitro DM degradability of spirulina. The DM was 56.1 and 57.1% in CS and NCS, respectively. The proximate composition for CS and NCS as a percentage of DM, respectively was: 60.8 and 62.5 for crude protein (CP); 0.97 and 1.05 for Ether extract (EE); 6.35 and 7.55 for ash. The CS and NCS contained: 0.25 and 0.37% DM Acid Detergent Fiber (ADF) and 1.03 and 1.92 % DM Neutral Detergent Fiber (NDF), respectively. The gross energy (cal/g DM) was 5730 and 5629 in CS and NCS, respectively. The CS produced more in vitro gas (73 and 71 ml/200mg DM) from 12 hr until the end of the experimental period (96 hr) compared to the NCS (51 and 48 ml/200mg DM), respectively. The CS had significantly higher metabolizable energy (ME) (approximately 12 MJ/kg DM) than NCS (about 9 MJ/kg DM). CS had significantly higher (81 and 79%) Organic Matter Digestibility (OMD) than NCS (61 and 58%). The CS had significantly higher Short Chain Fatty Acids (SCFA) (1.7 and 1.6 µmol) than NCS (1.2 and 1.1 µmol). It was concluded that spirulina is an excellent source of protein and can be used after drying as a potential animal feed. There was little effect of the method of drying of spirulina on its chemical composition or digestibility.

Authors: Sherwani Neelam
Published: February 2020

The present study evaluated the floristic diversity and biological spectrum of Muscat Governorate, Sultanate of Oman. Heterogeneity of geology, topography and climatic conditions create a diverse array of habitats across the 3,500 km2 study area, supporting a range of vegetation types. Floristic studies were conducted across 42 sites spread across various habitats such as sand dunes, alluvial plains, gravel plains, wadis, saline dunes, coastal areas, farms and plantations. A total of 264 species belonging to 183 genera and 54 families of angiosperm were documented during sampling the vegetation from different wilayats of the Governorate. Maximum number of species belonged to family Fabaceae (14%), followed by Poaceae (12%), Asteraceae (9%), Apocyanaceae and Convolvulaceae (3.66% each), Boraginaceae, Euphorbiaceae, Zygophylaceae (3% each). The biological spectrum was represented almost equally by therophytes and chamaephytes (30% each), followed by phanerophytes (19%), hemicryptophytes (13%), geophytes (4%), liana (3%), and helophytes (1%). The dominance of therophytes and chamaephytes reveals a thero-chamaephytic phytoclimate for the area. Different habitats are characterized by specific plant assemblages, but some species such as Acacia tortilis, Prosopis cineraria, Tetraena quaterense, Dipterygium gluacum, Aerva javanica, due to their broad ecological tolerance and adaptations, inhabit more than one habitats, while some species are just confined to certain parts of a single habitat.
Documenting ICE
Authors: Bruner Mia Eloise
Published: February 2020

On July 14th, 2017, the National Archives and Records Administration (NARA) posted a notice in the Federal Register that U.S Immigration and Customs Enforcement (ICE) was seeking permission to destroy eleven types of records related to people detained by ICE. These include records of sexual abuse and assault, escapes, deaths, solitary confinement, and complaints made to a hotline by those in ICE custody. ICE requested timelines for the destruction of these records ranging from three to twenty years and in late August 2017, NARA granted preliminary approval of this request. This perspective essay seeks to shed light on the vast array of arguments asserting the value of these records to the people in ICE detention. Moreover, it attempts to weigh the evidence of ICE’s recordkeeping practices, the preponderance of which points to ICE’s inability and aversion to accurate, truthful and accessible documentation surrounding its operation. This exploration ultimately considers this historical moment as one in which archives can show their value as resources for government accountability, historical research and communities of migrants and refugees to argue that it is incumbent upon archivists to seize the opportunity.
Discriminatory Practices in School Environment and Their Elimination Through School Mediation in Slovakia
Authors: Vanková Katarína
Published: February 2020

Teaching about human rights and freedoms means teaching about human dignity, tolerance between people, acceptance of people as they are, justice, equality, self-control, and self-assertiveness. Not to allow unfairness, deception, injustice, inequality, the humiliation of oneself and others. Tolerance in the school environment includes the acceptance of different views, different behaviors, a different relationship, but also toleration and patience in relation to others. A pupil who is unable to cope with conflicts is unable to adapt to changes and risks his own decline. The main problem is not that there are conflicts between us, but in the way how we respond to them, how we can deal with them, and what we do to prevent them, or what we do to successfully resolve them. Conflicts in the school environment are a natural part of school life, indicating, in particular, the presence of differences. Conflict resolution through school mediation represents the ability to not only perceive, understand but particularly respond to and resolve conflict situations with the help of a third neutral person. School and peer mediation can be a way how to teach pupils to develop strong friendships, even in an environment of diversity and differences; it can be a preparation for inclusive educational system.
Fuzzy Expert System Generalised Model for Medical Applications
Authors: Masivi Osée Muhindo
Published: February 2020

Over the past two decades an exponential growth of medical fuzzy expert systems has been observed. These systems address specific forms of medical and health problems resulting in differentiated models which are application dependent and may lack adaptability. This research proposes a generalized model encompassing major features in specialized existing fuzzy systems. Generalization modelling by design in which the major components of differentiated the system were identified and used as the components of the general model. The prototype shows that the proposed model allows medical experts to define fuzzy variables (rules base) for any medical application and users to enter symptoms (facts base) and ask their medical conditions from the designed generalised core inference engine. Further research may include adding more composition conditions, more combining techniques and more tests in several environments in order to check its precision, sensitivity and specificity.
Minimal Total Weighted Tardiness in Tight-Tardy Single Machine Preemptive Idling-Free Scheduling
Authors: Romanuke Vadim
Published: February 2020

Two possibilities of obtaining the minimal total weighted tardiness in tight-tardy single machine preemptive idling-free scheduling are studied. The Boolean linear programming model, which allows obtaining the exactly minimal tardiness, becomes too time-consuming as either the number of jobs or numbers of job parts increase. Therefore, a heuristic based on remaining available and processing periods is used instead. The heuristic schedules 2 jobs always with the minimal tardiness. In scheduling 3 to 7 jobs, the risk of missing the minimal tardiness is just 1.5 % to 3.2 %. It is expected that scheduling 12 and more jobs has at the most the same risk or even lower. In scheduling 10 jobs without a timeout, the heuristic is almost 1 million times faster than the exact model. The exact model is still applicable for scheduling 3 to 5 jobs, where the averaged computation time varies from 0.1 s to 1.02 s. However, the maximal computation time for 6 jobs is close to 1 minute. Further increment of jobs may delay obtaining the minimal tardiness at least for a few minutes, but 7 jobs still can be scheduled at worst for 7 minutes. When scheduling 8 jobs and more, the exact model should be substituted with the heuristic.

Published: February 2020

Hot-dip galvanized coatings represent a protection based on passivation of the single zinc layer. It is one of the most commonly used surface treatments of steel. However, pure zinc forms merely an insignificant upper layer. Coating crosscut is formed by intermetallic phases that can cause decrease in the level of anticorrosion protection. This results from an iron diffusion from the base material. Goal of this paper is to analyse the changes in the mechanical properties of these phases in relation to zinc coating heat treatment. For the experiment, annealing temperatures of 200 °C and 300 °C were used, and the staying time was set at 1, 3 and 5 hours. Furthermore, samples without any heat treatment were subjected to comparison as well. Moreover, following tests were conducted: bending test in compliance with the ČSN EN ISO 1519 standard, and tearing test (in accordance with the ČSN EN ISO 4624 standard). On the basis of performed tests, the changes in mechanical properties of the zinc coating after heat treatment could be analysed.

Published: February 2020

Mediterranean semi-arid region is sensitive to physical, chemical and biological soil disturbances related to intensive tillage. Presented field experiment was conducted at Razan district, Hamedan, located in central west zone, Iran during the 2017–2018 growing season. It dealt with the effects of different tillage methods and treatments on growth, yield and yield contributing characters of spring Kabuli chickpea (Cicer arietinum L.) under irrigated condition. Effects of two tillage methods – inversion tillage (mouldboard ploughing – T1) and non-inversion tillage (chisel ploughing – T2) – in combination with five different fertilization treatments (C: complete fertilizer; 20FYM: 20 Mg·ha−1 farmyard manure; 40FYM: 40 Mg·ha−1 farmyard manure; NPK: nitrogen, phosphorus, and potassium at 2-1-1 ratio; 0: no fertilizer for the control purposes) were studied. The experiment was carried out in split block design with three replications. Results showed that application of 40FYM under T1 condition significantly decreased the number of days to seedling emergence. The highest number of days to flowering was recorded for plants cultivated with inorganic fertilization and reduced tillage. Application of large amounts of FYM significantly increased the ground cover and canopy width for both tillage methods. The highest number of secondary branches was recorded for combination 40FYM – T1, which was followed by C – T2. The pod number per plant was considerably sensitive to different combination of treatments and the best results were recorded for combinations 40FYM – T2; 20FYM – T2; and 40FYM – T1. A similar trend was also recorded for the total dry matter. The heaviest seeds were observed in cases with the application of high levels of FYM. The highest seed yield was observed for plants cultivated using 40FYM – T2. Furthermore, the highest harvest index was recorded for 40FYM – T2, and C – T2. The results indicate that non-inversion tillage together with high-level FYM application can significantly affect the yield levels.

Authors: Salimi Mahdi , Pourdarbani Razieh , Nouri Bagher Asgarnezhad
Published: February 2020

Taking into account that traditional agricultural methods reduce the farm performance and make agriculture economically ineffective, development of intelligent machinery is essential for improving the quality of crops and agricultural activities. The most important issue in development of agricultural technologies lies in users’ willingness to adopt it. Therefore, the purpose of this study is to investigate the key factors of Davis’s model in automation acceptance in agriculture. Presented paper describes an applied research with a survey approach through a questionnaire. Questionnaire data were collected from 378 people and respondents include university students, farmers and experts in a randomized sampling from the Ministry of Agriculture. Firstly, the questionnaire data were described in a form of statistical numerical characteristics. Secondly, in order to verify the data normality, the Kolmogorov-Smirnov test was calculated in SPSS and the relationship between the variables was investigated in the conceptual model. Subsequently, hypotheses were tested via appropriate statistical models using LISREL and SPSS software. The results showed that for all hypotheses, the T-test exceeds 1.96 and the significance level is less than 0.05. In such a manner, all hypotheses were confirmed at 95% level, and the path coefficients in the hypotheses H1, H2 and H6 were negative – indicating the negative effect of the independent variable on the dependent variable in the hypothesis. In the other hypotheses, these were positive – indicating the positive effect of the independent variable on dependent variable. By means of modelling, it was found that there was an inverse relationship between social and individual factors with perceived usefulness, as well as an inverse relationship between social factors with perceived ease-of-use, while there was a positive and significant relationship between other factors. According to a set of fitting indices, the research conceptual model was appropriate and Cronbach’s coefficients for each factor were greater than 0.7, suggesting that the questionnaire was valid. On the basis of findings, the better a person understands the usefulness of automation, the more likely this person is to adopt it. Since the risk and issues related to it play an important role in farmers’ decision making, it is recommended that future studies address the issue of risk in adopting precision farming technology.

Ammi visnaga (Av) is a source of khellin where a tea made from the fruit of this plant was used as herbal medicine for kidney stones in Egypt. In the present research, the acute and subacute toxicity studies with oral intake of 150, 300 and 600 mg/kg of Av seed ethanolic extract in rats were done. In acute toxicity test, 4 groups of rats (n = 6/group: 3 males and 3 females) were chosen and the first control group received tap water, while the other three groups received Av seed ethanolic extract dissolved in tap water at doses of 150, 300, and 600 mg/kg, and general behavior, adverse effects, and mortality were recorded for up to 14 days. In subacute toxicity study, 72 rats (36 males and 36 females) were divided into 4 major groups; group I received tap water (control group), while animals in groups II, III, and IV (test groups) received oral intake of Av seed ethanolic extract dissolved in tap water at doses of 150, 300 and 600 mg/kg bwt, respectively. Each of this major group was subdivided consequently into 3 subgroups (n = 6/group: 3 males and 3 females) where brain tissue, blood sample, body and organs weights were recorded at the beginning and then after two and four weeks of the experiment for the determination of hematological, biochemical and histopathological changes in tissues (liver, kidney, brain, spleen, heart, testis and ovary). With regard to acute toxicity, Av seed ethanolic extract did not induce any toxic effects or death or any organ toxicity. In subacute toxicity study; oral intake with Av seed ethanolic extract did not reveal any change in body and organs weights, hematological parameters, serum glucose and cholesterol, brain neurotransmitters, liver and kidney functions, male and female hormones. In conclusion, Av seed ethanolic extract is nontoxic to liver, kidney, brain, spleen, heart, testis and ovary.

The present study was designed to investigate the chemoprotective effect of green tea extract (GTE), rosmarinic acid (RA) and rosemary extract (RE) against diethylnitrosamine (DEN) initiated and ferric nitrilotriacetate (Fe-NTA) promoted nephrotoxicity in rats. Forty male rats were categorized into five: Group I included healthy rats, group II received DEN+Fe-NTA, group III received 200 mg/kg b.wt. of RE+DEN+Fe-NTA, group IV received 1 g/kg b.wt. of GTE+DEN+Fe-NTA and group V received 50 mg/kg b.wt. of RA+DEN+Fe-NTA. RE, GTE, RA were given orally for 14 days before single intraperitoneal administration of DEN (160 mg/kg) till the end of the experiment. Eighteen days after DEN, a single intraperitoneal dose of Fe-NTA (5 mg Fe/kg) was administrated to rats to promote nephrotoxicity. The biochemical parameters were analyzed in serum at time intervals while the malondialdehyde (MDA) and tumor necrosis factor-alpha (TNF-α) were assessed in both serum and renal tissues. Kidney from each group was histopathologically examined at time intervals. The administration of Fe-NTA after DEN dose to albino rats resulted in acute nephrotoxicity which was characterized by a highly significant elevation of serum urea, creatinine, uric acid (p=0.000), serum and renal MDA and TNF-α (p=0.000) with vacuolation of epithelial lining renal tubules. The administration of RE, GTE and RA prior to DEN+Fe-NTA treatment significantly ameliorated the observed increased levels of the above mentioned parameters. GTE, RA & RE exerted a protective effect against renal toxicity with GTE showing a more pronounced effect on renal function parameters while RA showed the best antioxidant impact.

Published: February 2020

We have earlier demonstrated the potential of monocrotophos (MCP), a highly toxic organophosphorus insecticide (OPI), to elicit insulin resistance in rats after chronic exposure. Given the understanding of role of paraoxonase1 (PON1) in OPI toxicity and diabetes pathology, this study was envisaged to understand the effect of duration of exposure to MCP on plasma PON1 activity in rats. Rats were administered MCP per os at 1/20 and 1/10th LD50 as daily doses for 180 days. Interim blood samples were collected at 15, 30, 45, 90 and 180 d for analysis of plasma parameters. Exposure to MCP for 45 resulted in persistent trend of hyperinsulinemia, while significant increase in fasting glucose levels was observed after 180 days. MCP caused suppression of plasma cholinesterase activity though the study period, albeit extent of inhibition was more severe during the early phase of the study. Exposure to MCP for 180 d resulted in hypertriglyceridemia and marginal decrease in HDL-C levels. MCP failed to modulate PON1 activity in plasma during the early phase of the study (up to 45 d). However, prolonged exposure resulted in significant increase in the plasma PON1 activity. This suggests that manifestation of insulin resistance in rats subjected to chronic exposure to MCP is associated with increase in PON1 activity. Our work provides rationale for studying whether the increase in PON1 activity observed in the present study serves to counter the deleterious effect of long term exposure to organophosphorus insecticides on metabolic homeostasis.

Significantly, the purpose of urban transport is to provide both passenger and freight mobility over specific parts of urban areas including cities, and its efficiency is characterized upon transporting effectively and achieving economies of scale. Hence, this study examined intra-city mobility and characterization in Lagos, Nigeria. The data was sourced from both primary and secondary sources. Primary data detailed the use of two sets of questionnaires administered to commuters and motorists. 182 copies of questionnaire were randomly administered to commuters, while 60 units of the questionnaire were purposively and conveniently administered to motorists. Descriptive and inferential techniques were used for data analysis. Major findings revealed obvious variations in socio-economic parameters of intra-city trip makers and factors influencing trip making. It was observed that journey to work, school, shopping cum business constituted the major trips characterizing in Lagos. Findings also revealed that high patronage priority was given to most used and preferred means due to vehicle travel speed, trip purpose, and availability than safety and comfortability of modal choice. Regression analysis result revealed that commuters’ modal choice and patronage is statistically influenced by operational attributes of mode (e.g. transit time, delay duration, safety, vehicle condition and transit fare etc.) at Sig. p=0.000 and F14
165 15.667 which is greater than table value at 5% significant level. The study recommended among others the formulation and implementation of effective policy for urban transport activities; standardization of service operations and expansion of infrastructural facilities including the last-mile in the city.

Published: February 2020

Electric load forecasting (ELF) is a vital process in the planning of the electricity industry and plays a crucial role in electric capacity scheduling and power systems management and, therefore, it has attracted increasing academic interest. Hence, the accuracy of electric load forecasting has great importance for energy generating capacity scheduling and power system management. This paper presents a review of forecasting methods and models for electricity load. About 45 academic papers have been used for the comparison based on specified criteria such as time frame, inputs, outputs, the scale of the project, and value. The review reveals that despite the relative simplicity of all reviewed models, the regression analysis is still widely used and efficient for long-term forecasting. As for short-term predictions, machine learning or artificial intelligence-based models such as Artificial Neural Networks (ANN), Support Vector Machines (SVM), and Fuzzy logic are favored.
Analysing picking errors in vision picking systems

Published: February 2020

Vision picking empowers users with access to real-time digital order information, while freeing them from handheld radio frequency devices. The smart glasses, as an example of vision picking enabler, provide visual and voice cues to guide order pickers. The glasses mostly also have installed navigation features that can sense the order picker’s position in the warehouse. This paper explores picking errors in vision systems with literature review and experimental work in laboratory environment. The results show the effectiveness of applying vision picking systems for the purposes of active error prevention, when they are compared to established methods, such as paper-picking and using cart mounted displays. A serious competitor to vision picking systems are pick-to-light systems.

The strong advantage of vision picking system is that most of the errors are detected early in the process and not at the customer’s site. The cost of fixing the error is thus minimal. Most errors consequently directly influence order picker’s productivity in negative sense. Nonetheless, the distinctive feature of the system is extremely efficient error detection.

El turno de la didáctica de la historia: contribuciones para un debate
Authors: Moreira dos Santos Schmidt Maria Auxiliadora
Published: February 2020

El trabajo busca presentar reflexiones en torno a la renovación del campo de la enseñanza de la Historia, tomando como presupuesto el hecho que el cambio que ocurrió en la concepción del aprendizaje histórico produjo nuevas posibilidades para la enseñanza y para la Didáctica de la Historia. La nueva concepción de aprendizaje toma como referencia la filosofía y la teoría de la Historia y no sólo la psicología del aprendizaje. Para responder las preguntas que suscitan las relaciones entre el desarrollo del pensamiento histórico y la formación de la conciencia histórica, se  remite al diálogo con el pensamiento de Jörn Rüsen, buscando con ello fundamentación para una teoría del aprendizaje, basada en la ciencia de la Historia que sea orientadora del significado y función  del aprendizaje histórico como el centro de la Didáctica de la Historia. Al situar el problema de la Didáctica de la Historia en la naturaleza de la relación con la teoría y la filosofía de la Historia, el autor abre posibilidades para tener en cuenta algunos principios que serían constitutivos de la epistemología de este campo del conocimiento, con implicaciones para la metodología de la Enseñanza de la historia. Entre los principios orientadores, están: 1. La teoría de la historia como fundamento para una teoría de la didáctica específica de la historia. 2. La conciencia histórica como punto de partida y de llegada del aprendizaje histórico. 3. La competencia de generación de sentido a través de la narrativa como forma y función del aprendizaje histórico. 4. La formación histórica de sentido como principal problema del aprendizaje histórico.

Published: February 2020

Colombia se considera uno de los países con la mayor biodiversidad a nivel global. Una parte importante de esta biodiversidad se alberga en los ecosistemas de la región de los Andes, donde además se tiene un alto endemismo de especies. La cuenca alta y media del río Cali hace parte de esta región, por lo que la diversidad de especies, funciones e historia evolutiva de los diferentes ecosistemas ubicados en esta cuenca resultan clave para la conservación de la biodiversidad nacional y mundial. No obstante, en la actualidad se desconoce cuánta diversidad representan dichos ecosistemas y, por ende, ¿cuántas especies que componen esta diversidad se encuentran realmente amenazadas? En la cuenca se registra gran cantidad de actividades antrópicas, desde la agricultura y la ganadería hasta la minería, las cuales generan una presión importante sobre los componentes bióticos y abióticos de la cuenca, pero se desconoce cuáles de estas actividades explican mayormente efectos como la transformación, degradación y pérdida de las coberturas naturales y el riesgo de extinción de las especies. Este trabajo plantea abrir una discusión sobre el estado actual del conocimiento sobre la biodiversidad de la cuenca alta y media del río Cali y su nivel de conservación, la valorización de la influencia que las actividades antrópicas encontradas en la cuenca ejercen sobre la degradación y/o pérdida de la cobertura natural y ciertas acciones de conservación, restauración y manejo sostenible que se podrían tener en cuenta en el contexto de los efectos globales que comprende el cambio climático y los efectos locales de las presiones antrópicas conocidas en la zona de la cuenca, para en un futuro con un trabajo mancomunado y adecuado entender qué tanta de esta biodiversidad podrá permanecer en el tiempo.

Published: February 2020

Becoming country prone to the occurrence of natural disasters, determination on risk variables affecting successful operation of disaster response service supply chain using supply chain FMEA (Failure Mode and Effect Analysis) is undeniably important to support successfulness of humanitarian operation. However, scientific studies concerning on integrating SCOR into Risk evaluation of disaster response supply chain is rarely found in references. To response such gap, this paper presents a conceptual model on integrating disaster response supply chain FMEA with Supply Chain Operational Reference (SCOR) to determine a conceptual risk-based performance evaluation model in disaster response supply chain. A framework on integrating Service Supply Chain FMEA with SCOR is presented coupled with a decision support model for evaluating criticality of risk-based performance index and followed with discussions and new opportunity for further investigations.

Published: February 2020

Insider threats become one of the most dangerous threats in the cyber world as compared to outsider as the insiders have knowledge of assets. In addition, the threats itself considered in-visible and no one can predict what, when and how exactly the threat launched. Based on conducting literature, threat in Automated Manufacturing Execution Systems (AMESs) can be divided into three principle factors. Moreover, there is no standard framework to be referring which exist nowadays to categorize such factors in order to identify insider threats possible features. Therefore, from the conducted literature a standard theoretical categorization of insider threats framework for AMESs has been proposed. Hence, three principle factors, i.e. Human, Systems and Machine have considered as major categorization of insider threats. Consequently, the possible features for each factor identified based on previous researcher recommendations. Therefore, via identifying possible features and categorize it into principle factors or groups, a standard framework could be derived. These frameworks will contribute more benefit specifically in the manufacturing field as a reference to mitigate an insider threat.
