Design, Building and Performance Evaluation of a Mixed-Mode Solar Dryer for Agricultural Products
Authors: El-Ghobashy El-Hagar Mahmoud Mohamed
Published: May 2020

This research work presents the detailed explanation of the design, construction and performance evaluation of mixed-mode solar agricultural products dryer. The experimental set up used for testing the performance of the mixed-mode solar agricultural products dryer and determining the influence of various drying methods on the drying behaviour of agricultural products. Evaluation of the dryer was centered on the moisture content reduction, temperatures and relative humidities variations. 1680 g of freshly potato slides were used for evaluation. The test results gave that the temperatures inside the dryer cabinet and the solar collector were much higher than the ambient temperature during most hours of the daylight. The temperature inside the solar collector was up to 27 o C approximately higher than the ambient temperature. The temperature inside the drying cabinet was up to 22 o C approximately higher than the ambient temperature for about three hours immediately after 12.00 h (noon). The relative humidity in the solar collector and drying cabinet were lower than the ambient air relative humidity, with the ambient air recording the highest relative humidity at each reading followed by the drying cabinet and finally by the solar collector. Because of the decreased relative humidity inside the dryer, all the time, the temperature inside the dryer was high which is sufficient enough to dry the potato at an early time. Based on the results obtained during the test, temperature above 65 o C was recorded inside the drying cabinet. This high temperature in the drying cabinet causes 419 g of moisture to be removed on the first day, 257 g on the second day, 191 g on the third day, 136 g on the fourth day and finally 108 g on the fifth day. At the end of the five days of drying process, the mass of 1680 g of potato was reduced to 569 g. Total amount of moisture removed was 1111 g and total moisture loss was 66.1 %, which is the required amount of moisture to be removed for safe drying of freshly potato slides. The moisture content of the freshly potato slides was 24.9 % at the end of drying for the first day at about 5:00 pm, 20.4 % at the end of drying for the second day, 19 % at the end of drying for the third day, 16.7 % at the end of drying for the fourth day and finally 15.9% at the end of drying for the fifth day. It was observed that the drying rate increased from the end of one day to another, which shows the earlier and faster removal of moisture from the dried item.

Murroksia ja jatkuvuutta
Authors: Ovaska Juho
Published: May 2020

Artikkelissa analysoidaan 1980-lukua käsittelevän suomalaisen historiantutkimuksen ja presidentti Mauno Koiviston muistelmien pohjalta muodostuvia historiakuvia. Lähtökohtana artikkelissa on arkikäsitykseen pohjautuva vuosikymmenjaottelu, jonka avulla tarkastellaan historiantutkimuksen kohdistumista 1980-luvun eri aihepiirien tutkimukseen. Suomalaisessa yhteiskunnassa tapahtuneita merkittäviä rakenteellisia muutoksia oli 1980-luvulla sisäpoliittisten voimasuhteiden muuttuminen, talouselämän sääntelyn ja ideologisen ajattelun muutokset sekä media-alan murros. Ulkopolitiikassa sen sijaan korostettiin jatkuvuutta. Koiviston tyyli kuvata tapahtumat muistelmissaan rauhallisina, vailla paniikkia ja kriisitunnelmia, on korostanut 1980-luvusta vallitsevaa vakauden vaikutelmaa. Muistelmissa heijastuu Koiviston ”matalan profiilin” poliittinen strategia 1980-luvun tapahtumahistorian kuvauksessa. Kansallisesta näkökulmasta vuosikymmen ei sisällä suurta dramatiikkaa syksyn 1981 presidentin virkakauden ennenaikaisen päättymisen ja syksyn 1989 kansainvälisten murrosten välisenä ajanjaksona, mutta 1980-lukua käsittelevä historiantutkimus heijastaa yhteiskunnan eri osa-alueilla tapahtuneita laaja-alaisia muutoksia. Tapahtuneiden muutosten hidastempoisuus on saanut muutokset näyttämään vakailta ja hallituilta, jolloin vuosikymmen näyttäytyy poikkeuksellisen kriisittömänä ajanjaksona Suomen 1900-luvun historiassa.
DDR:n tieteellis-tekninen vakoilu kylmän sodan aikana: Esimerkkinä tapaus IM ”Larsen”
Authors: Elo Kimmo
Published: May 2020

Tässä artikkelissa analysoidaan DDR:n turvallisuusministeriön eli Stasin tietolähteenä 1980-luvulla peitenimellä “Larsen” toimineen suomalaistutkijan toimintaa osana laajempaa tieteellis-teknisen tiedustelun verkostoa. Stasin länsimaissa harjoittamalla tieteellis-teknisellä tiedustelulla oli etenkin 1970-luvun jälkimmäiseltä puoliskolta lähtien merkittävä rooli pyrkimyksissä kompensoida suunnitelmatalouden heikkouksia ja jälkeenjääneisyyttä sekä kuroa kiinni teknologista jälkeenjääneisyyttää erityisesti korkean teknologian sektoreilla. Tämä tiedusteluhaara organisoitiin jo vuonna 1971 Stasin sisällä omaksi “tieteen ja tekniikan sektoriksi” (Sektor Wisseschaft und Technik). Sotilaalliseen varustautumiseen liittyvän tiedustelun kautta puolestaan pyrittiin hankkimaan tietoja vastapuolen, erityisesti NATO:n aseteknologioista, mitä tietoa välitettiin laajasti myös Neuvostoliiton varusteluteollisuuden käyttöön. Tieteellis-teknisen sektorin operatiivisen toiminnan kannalta Analyysin perusteella “Larsen” oli monessakin suhteessa ideaali tietolähde. Hänellä näyttää olleen vahva poliittis-ideologinen motiivi, pitkäaikainen ja luonteva yhteys itäsaksalaiseen kollegaan sekä – ehkä olennaisimpana – mahdollisuus saada haltuunsa sotilasteknologista tiedustelutietoa Naton aktiviteeteista erityisesti EISCAT-tutkahankkeeseen liittyen. “Larsen” toimikin osana pientä tiedustelulähteiden verkostoa, jonka kautta Stasin ulkomaantiedustelu hankki tiedustelutietoa ensisijaisesti avaruus-, teollisuus- ja sotilasteknologiaan liittyen, Vaikka käytettävissä olevien aineistojen perusteella ei voidakaan kattavasti analysoida “Larsenin” toimittamien tietojen hyödyllisyyttä tai käyttöä DDR:n sisällä, voidaan Stasin harjoittaman tiedustelutoiminnan analysoinnista saada välineitä ymmärtää tieteellis-teknisen ja taloudellisen tiedustelun merkitystä myös kylmän sodan kontekstia laajemmassa tarkastelussa.

This study aims to know why gender responsive budgeting is not responsed by local government. Since it was issued by president as we know as Presidential Instruction Number 9 of 2000, there was no any significance changin in gender equality. This research was developed by some previous researches in Indonesia that found many regulations have setted to promote gender equality, but there was no significant action that showed by local government to implement it. So, this study try to seek what the obstacle that hampered gender reponsive budgeting implementation in local government. Documentation study and depth interview were the the tools to capture the data. The research found some obstacles such us the understanding of gender concept among government official, political will, and resistance to change. Some strategies to handle these obstacles are (1) political committment affirmation; (2) technical capacity affirmation; (3) accountability; (4) establish planning and budgeting department; (5) build the network  with  private  sector,  academicion,  and  society  empowerment  activity group. Contribution of this research include to developed theory in public sector accounting especially in budgeting process, and give understanding about gender responsive budgeting in local government. The last important contribution is to give suggestion and overview for Manado City governement to start gender responsive budgeting implementation.

Published: May 2020

Structural colours have received a lot of attention regarding the reproduction of the vivid colours found in nature. In this study, metal–anodic aluminium oxide (AAO)–Al nanostructures were deposited using a two-step anodization and sputtering process to produce self-ordered anodic aluminium oxide films and a metal layer (8 nm Cr and 25, 17.5 and 10 nm of Au), respectively. AAO films of different thickness were anodized and the Yxy values (Y is the luminance value, and x and y are the chromaticity values) were obtained via reflectance measurements. An empirical model based on the thickness and porosity of the nanostructures was determined, which describes a gamut of colours. The proposed mathematical model can be applied in different fields, such as wavelength absorbers, RGB (red, green, blue) display devices, as well as chemical or optical sensors.

Objectives. Approaching acute diarrheal disease (ADD) in pediatric patient, we have set as a primary objective a throughout evaluation of etiology and risk factors and, on the other hand the risk/benefit assessment regarding the justification of antibiotic therapy in the treatment of ADD in pediatric patient. Material and method. We performed an analytic, descriptive study, in which we included 125 patients admitted in the 1st Pediatrics Clinic of Tg. Mureș during 2016 (January to December), diagnosed with ADD. Results. The study group comprised 125 patients, out of which a bacterial etiology was noticed in 23 cases (18.4%). On the other hand, it was observed that 84 patients received antibiotics (67.2%), 110 patients (88%) received symptomatic treatment, and in 60% of the cases (75 patients), a probiotic was associated. The medium hospitalization length was of 5 days, depending on the presence/absence of risk factors such as fever, inflammatory syndrome, hydro-electrolytical imbalances or acute dehydration syndrome, risk factors that increased the medium hospitalization length with up to 2 days (p < 0.05). Conclusions. Antibiotics must be used rationally and justified in the treatment of ADD, analyzing carefully the risk/benefit ratio. Taking into account the self-limiting character and the favorable prognosis of this disorder, we conclude that we face an abuse of antibiotics in case of pediatric patients diagnosed with ADD.
Correction of disordered mineral bone metabolism in patients affected by chronic periodontitis
Authors: Yarmoshuk Iryna
Published: May 2020

One of the main mechanisms in pathogenesis of chronic periodontitis is disordered bone metabolism that is accomplished by cortical plate’s resorption, destruction of the interdental septums and osteoporosis of the jaws. Administration of osteotropic agents will allow achieving efficient results in treatment of the patients affected by periodontal disorders, lower the tendency of bone resorption and stimulate the processes of regeneration.

The article demonstrates the results obtained after the surgical treatment of the patients with osteopenia affected by chronic periodontitis of II–III degree that were administered simultaneously with synthetic osteoplastic material Tricalcium phosphate and a bone resorption inhibitor Ibandronic acid. It has been established the high efficiency of the recommended treatment that was proved by positive progress of biochemical markers of bone metabolism in blood serum and urine of the individuals from the main group taken 24 month after the beginning of the treatment. The study shows that the reis arise of osteocalcin by 11,5% in the blood serum of the main group patients 2 years after the research and the amount of desoxypiridynolin, on the other hand, was by 21,72% lower comparing with those from the main group (р < 0,05).

Published: May 2020

This study provides information about the feeding habits, population aspects and spatial distribution of the spot­ted goatfish, Pseudupeneus maculatus, along the coast of the tropical Brazilian continental shelf. Distribution patterns are described using length frequencies and catch rates. Stable isotope ratios of carbon (δ13C) and nitrogen (δ15N), along with stomach contents, were analysed to determine the diet of the spotted goatfish. Multivariate analysis and numerical indicators of the diet, such as numerical frequency, frequency of occurrence and weight percentage, were computed to evaluate the diet composition. The mean trophic position was defined using both stable isotope ratios and stomach content analysis. The length at first maturity for the species was determined as 13.7 cm. A slight pattern in size distribution was observed, with mean size increasing with depth along the shelf. The diet was mainly composed of crustaceans, teleosts and Polychaeta. No clear dietary difference was found between habitat types, water depth or latitude. Both trophic positions estimated by stable isotopes and stomach contents analysis ranged between levels 3 and 4. P. Maculatus was found to be feeding on many rare and infrequent prey items, classifying it as a generalist zoobenthivorous predator, probably due to its efficient search strategy.

Acrylamide (ACR) is among the most deleterious pollutants in the environment and presents a serious risk to humans and ecosystems. The purpose of this study was to assess its effects when administered at different concentrations (5, 10 and 20 mg L–1) to evaluate antioxidant status in the gills of Mactra stultorum. Our results showed, after five days of treat­ment, an increase in malondialdehyde (MDA), lipid hydroperoxides (LOOH), advanced oxidation protein products (AOPP), reduced glutathione (GSH), ascorbic acid (Vit C) and metallothionein (MDA) levels in gills of treated clams compared with controls. Moreover, an increase in superoxide dismutase (SOD) and a significant decrease in glutathione peroxidase (GPx) activities were also observed. Acrylamide induced neurotoxicity, as evidenced by the inhibition of acetylcholinesterase (AChE) activity in a dose-dependent manner. Overall, our results indicated that oxidative stress may be considered one of the mechanisms behind acrylamide toxicity in bivalves, although the subject requires more research.

Published: May 2020

The octopus fishery on the Campeche Bank (Yucatán, Mexico) is considered the third largest in the world. In Yucatán, two fleets target this resource: an artisanal fleet and a semi-industrial fleet. The artisanal fleet only catches Octopus maya, while the semi-industrial fleet catches two species, O. Maya and O. “vulgaris” Type II, because it operates at deeper waters ( > 30 m). Since there is no information on the abundance of O. “vulgaris” Type II, management is based only on O. Maya. In order to generate information about the abundance of this species, four fishing research cruises were carried out in the northeastern area of the continental shelf off the Yucatán Peninsula. Four methods (a stratified random method, a swept area, geostatistics and a weighted swept area) were applied and compared to determine the instantaneous abundance and biomass of both species in the study area. The lowest potential biomass was calculated with the geostatistical method, with values between 18.5% and 36.7% lower than the other three methods. O. “vulgaris” Type II showed the lowest biomass (37.8±3.36 t) during May and July and the highest (189.56±11.6 t) in December. Our findings revealed that the total abun­dance of both species was similar in the study area, with a geographic overlap whose amplitude changed throughout the year according to the geographic position: O. Maya dominated at approximately 88°W, while O. “vulgaris” Type II dominated towards the southeast at 87°W.

Tripartite motif-containing proteins (TRIMs) play a variety of recently described roles in innate immunity. Although many TRIMs regulate type I IFN expression following cytosolic nucleic acid sensing of viruses, their contribution to innate immune signaling and gene expression during bacterial infection remains largely unknown. Because Mycobacterium tuberculosis is an activator of cGAS-dependent cytosolic DNA sensing, we set out to investigate a role for TRIM proteins in regulating macrophage responses to M. tuberculosis. In this study, we demonstrate that TRIM14, a noncanonical TRIM that lacks an E3 ubiquitin ligase RING domain, is a critical negative regulator of the type I IFN response in Mus musculus macrophages. We show that TRIM14 interacts with both cGAS and TBK1 and that macrophages lacking TRIM14 dramatically hyperinduce IFN stimulated gene (ISG) expression following M. tuberculosis infection, cytosolic nucleic acid transfection, and IFN-β treatment. Consistent with a defect in resolution of the type I IFN response, Trim14 knockout macrophages have more phospho-Ser754 STAT3 relative to phospho-Ser727 and fail to upregulate the STAT3 target Socs3, which is required to turn off IFNAR signaling. These data support a model whereby TRIM14 acts as a scaffold between TBK1 and STAT3 to promote phosphorylation of STAT3 at Ser727 and resolve ISG expression. Remarkably, Trim14 knockout macrophages hyperinduce expression of antimicrobial genes like Nos2 and are significantly better than control cells at limiting M. tuberculosis replication. Collectively, these data reveal an unappreciated role for TRIM14 in resolving type I IFN responses and controlling M. tuberculosis infection.

We describe a case of acute myocarditis, which was reported as the main COVID-19 clinical manifestation, with a favorabile outcome. In addition to symptoms, laboratory tests (BNP and troponin), echocardiogram and cardiac MRI contributed to diagnosis. Regardless heart biopsy was not obtained, it is likely an immunological pathogenesis of this condition which pave the way to further therapeutic implications, since there are currently no standardized treatments.
Management of cytotoxic chemotherapy-induced hand-foot syndrome

Published: May 2020

Improvements in systemic cancer treatments have resulted in more patients surviving for prolonged periods of time on treatment. This has made treatment-related toxicity and quality of life concerns increasingly relevant. Hand-foot syndrome (HFS) is a common skin reaction to systemic therapy that should be anticipated with chemotherapeutic treatments such as pegylated liposomal doxorubicin, docetaxel, and fluoropyrimidines. In this review we discuss current knowledge of the diagnosis, incidence, pathogenesis, and management of hand-foot syndrome (HFS). Although HFS is not life threatening, it can cause significant discomfort and impairment of function, especially in elderly patients, and may seriously impact quality of life. The incidence of HFS is dependent on the chemotherapeutic drug used, the treatment schedule, and the median duration of treatment. Effective measures for prevention and treatment of HFS include systemic and topical treatments, dose reductions, and switching to other drugs in the same class that are associated with lower rates of HFS. These approaches allow patients to continue cancer treatment while reducing negative impacts on quality of life. Awareness and early recognition are important to ensure timely treatment and avoidance of dose reductions or treatment discontinuation. We provide useful recommendations to guide the management of HFS in clinical practice.
Fetishist disorder
Authors: Delcea Cristian , EUSEI Dorina
Published: May 2020

Fetishism, as a technical descriptor of atypical sexual behaviour, was noted in the writings of the well-known nineteenth century French psychologist Alfred Binet (1857–1911) (Binet, 1887) as well as prominent European sexologists Richard von Krafft-Ebing (1840–1902) (Krafft-Ebing, 1886), Havelock Ellis (1859–1939) (Ellis, 1906), and Magnus Hirschfeld (1868– 1935) (Hirschfeld, 1956). In their seminal writings, all of the afore mentioned sexologists used the terms “fetish” and “fetishism” to specifically describe an intense eroticization of either non-living objects and/or specific body parts that were symbolically associated with a person. Fetishes could be non clinical manifestations of a normal spectrum of eroticization or clinical disorders causing significant interpersonal difficulties. Ellis (1906) observed that body secretions or body products could also become fetishist expressions of “erotic symbolism”. Freud (1928) considered both body parts (e.g., the foot) or objects associated with the body (e.g., shoes) as fetish objects. For the purposes of this review, a “broader” historically based core definition for Fetishism will include intense and recurrent sexual arousal to: non-living objects, an exclusive focus on body parts or body products.

BÜROKRATİK VESAYET ANLAYIŞINA CUMHURBAŞKANLIĞI HÜKÜMET SİSTEMİ’NİN ETKİSİ
Authors: MERCİMEK Şehriban
Published: May 2020

Bürokratik
elitlerin, ülke iç siyasi çekişmelerini öne sürerek seçilmiş siyasi iktidarı
vesayet altına alma girişimleri, 1960’lı yıllardan itibaren artan ve
tekrarlanan bir kısır döngü sürecine dönüşmüştür. Türk siyasal hayatının
darbelerle anılmasına sebep olan bu vesayetçi yaklaşım kendini korumaya alarak
kökleşmiştir. Türkiye Cumhuriyeti’nde 16 Nisan 2017 tarihinde gerçekleştirilen
referandum ile mevcut hükümet sistemi değişmiş ve Cumhurbaşkanlığı Hükümet
Sistemi ortaya çıkmıştır. Türk tipi Başkanlık Sistemi 24 Haziran 2018 seçimleri
ile uygulanmaya başlanmıştır ve mevcut birçok yapıda değişiklik öngörmektedir.
Bu değişimlerden birisi ve belki de en önemlisi Türk siyasal hayatı üzerinde
bir baskı aracı olarak yoğun bir şekilde kullanılan ve etkili de olan
bürokratik vesayet anlayışıdır. Cumhurbaşkanlığı Hükümet Sistemi’nin,
bürokratik vesayet kurumlarının vesayetçi tutumlarını zayıflatacağı ve bu
yapıların vesayetçi uygulamalarını ortadan kaldıracağı beklenmektedir.

Authors: Nusrat Afroz  , Zul Ilham
Published: May 2020

This study was performed to determine the awareness level of University of Malaya students towards Sustainable Development Goals (SDGs). A set of survey questionnaires based on knowledge, attitude, and practice (KAP) was distributed among all the students of University of Malaya and 382 responses were obtained to analyze the awareness level (95% confidence level with ±5% margin of error). Data analysis was performed SPSS Statistics version 20. Descriptive statistics showed that the respondents have high knowledge with a positive attitude towards SDGs. Spearman’s rho coefficient correlation was applied to determine the relationships between variables (knowledge with practice and attitude with practice). The results revealed a weak negative correlation between the knowledge and practice towards SDGs (r = -.264, N = 382, p = .00). However, there is a strong positive correlation between the attitude and practice towards SDGs (r = .440, n = 382, p =. 00).
The Urgency of Indonesia Social Media Regulation in the Vortex of Terrorism
Authors: Sutrisno FX Andy
Published: May 2020

Social media becomes a very important and strategic tool for terrorists to do propaganda, recruitment, funding, and facilitation of other terrorist activities. Both international level and national level, no regulation explicitly regulates the use of social media for terrorism. Since many incidents of terrorism using social media in Indonesia, the more vigorous terrorists’ propaganda and recruitment through social media, and considering opened terrorist access to pursue their targets, especially the youth generation, it is vital to specifically regulate social media and terrorism. Although social media and terrorism issues need to be addressed by the increasing of local government’s role in combating terrorism and the strengthening parental supervision in the use of social media by children, the need for social media and terrorism regulation is an urgent matter to do first, as a guide to tackling the social media use in the vortex of terrorism.

Due to the superb characteristics of its light-harvesting, the Perovskite sensitizer ABX3 (A = CH3NH3, B = Pb, Sn, and X = Cl, Br, I) has recently attracted great attention. Perovskite is composed of inexpensive and earth abundant materials. It is processable at low temperature preferably via the printing techniques. In addition, the charges in the bulk material after light absorption that enhances low loss in energy charge generation and collection were generated freely. In this research work, Solar cell capacitance simulator (SCAPS-1D) was used to harnessing the real device hybrid Perovskite (PSC) solar cell with material parameters obtained from literatures and experiment used in the definition panel and the arrangement of an hybrid (FTO/ZnO/CZTS/PSCS/CZTS/HTM) model in the SCAPS-1D simulator. From the simulated results obtained the Band gap diagram and other curves were constructed. The efficiency greater than twenty percent (>20%) was achieved, which shows that having a combination of two different absorbers were achievable and calling for great attention from the researchers.
Solution of Fractional Order Equations in the Domain of the Mellin Transform
Authors: Fadugba Sunday Emmanuel
Published: May 2020

This paper presents the Mellin transform for the solution of the fractional order equations. The Mellin transform approach occurs in many areas of applied mathematics and technology. The Mellin transform of fractional calculus of different flavours; namely the Riemann-Liouville fractional derivative, Riemann-Liouville fractional integral, Caputo fractional derivative and the Miller-Ross sequential fractional derivative were obtained. Three illustrative examples were considered to discuss the applications of the Mellin transform and its fundamental properties. The results show that the Mellin transform is a good analytical method for the solution of fractional order equations.

Published: May 2020

Surface plasmon resonance is the effect of electron oscillation in a structure stimulated by incident light. When noble materials such as Ag, Au or Cu are added into the titania (compact or mesoporous) structure of the sensitized solar cell, the plasmonic effect of such materials will result an improved performance of the device. Placing AgNPs at different position will produce a variety of result. In this work the systematic design and formation of plasmonic dye sensitized solar cells (DSSCs) by integrating Ag NPs nanoparticles (NPs) in two distinct configurations; on the c-TiO2 and on m-TiO2 were reported. The power conversion efficiency (PCE), Jsc and Voc of the reference device shows a value of 0.36 %, 1.89 mAcm-2 and 0.45 V. Upon introduction of AgNPs on the c-TiO2, a PCE of 0.64 %, Jsc of 2.53 mAcm-2 and Voc of 0.46 V were recorded, which improved the PCE ~ 63.90 % over that of the prestine device. When AgNPs is introduced on the m-TiO2, a PCE of 0.71 %, Jsc of 2.83 mAcm-2 and Voc of 0.46 V were obtained which which results to increase in power conversion efficiency (PCE) from 0.36 % to 0.71 %, demonstrating ~1.97 time’s enhancement, compared with the reference device without the metal NPs. The improvement is attributed to an increase in photocurrent density due to enhanced light harvesting by silver nanoparticles.
