Authors: Mualif A.
Published: August 2020

Bahasa arab adalah bahasa al-Qur’an, alat komunikasi dan informasi terutama umat Islam, bahasa arab juga merupakan kunci untuk mempelajari ilmu-ilmu lain karna buku-buku berbagai macam ilmu pada zaman dahulu banyak ditulis dengan menggunakan bahasa arab jadi kalau ingin menguasainya terlebih dahulu harus belajar bahasa arab. Tulisan ini dilatarbelakangi Al-Falsafah Al-Lughawiyyah wa Al-Fazhul Arobiyyah sebuah buku yang ditulis oleh Jurji Zaidan yang mengatakan bahwa bahasa Arab merupakan satu rumpun bahasa semit (samiah); yang paling luas struktur morfologis dan maknanya dan paling kaya derivasi (isytiqaq) dan struktur kalimatnya. Penelitian ini menggunakan teori deskripstif dengan pendekatan book survey. Tidak ditemukan dalam bahasa manapun di dunia, satu kata memiliki sepuluh sampai dua puluh arti bahkan lebih. Beraneka ragamnya struktur dan arti kosakata bahasa Arab, tidak terlepas dari beberapa teori semantik (dilalah), yang terdapat dalam khazanah bahasa ini, di antaranya teori isytiraakul lafzhi (satu kata banyak arti), al-taraduf (beberapa kata satu arti), al-adldad (satu kata berlawanan arti).

Published: August 2020

This paper describes the use of Scribe Video as a Media in Learning Arabic to Improve Student Learning Motivation. The problem of education and teaching is a fairly complex problem where there are many factors that influence it. One of these factors is the teacher. The teacher is a component of teaching that plays an important and primary role, because the success of the learning process is largely determined by the teacher's factor. The teacher's task is to convey the subject matter to students through communication interactions in the learning process that they do. The success of the teacher in delivering the material is very dependent on the smooth interaction between the teacher and the students. This study uses development research methods in education or in English development research, a process in developing and validating educational products. The purpose of this research is to develop Arabic learning media using software sparkol (video scribe) in increasing student learning motivation. This research is a research and development focusing on software sparkol (video scribe). Videoscribe is a software (software) for automatically creating whiteboard animation (whiteboard animation). Videoscribe was launched in 2012 by sparkol company United Kingdom (UK) in the UK. Videoscribe is developed by Adobe Flash and Flash Video. Videoscribe is a form of video media with a blackboard concept that uses hand drawings and as if it were drawing or writing on the board. The concept of videoscribe is usually used as a video presentation, promotion, learning, and so on.

I denne artikel tages Samfundslederskab bogstaveligt, idet det er Socialdemokratiet, der her er i centrum. Artiklen tager udgangspunkt i to forskellige cases, som begge har betydelige fællestræk i forhold til at vogte om demokratiet og den demokratiske dialog. Hovedtemaerne er Socialdemokratiets gradbøjning af demokratiet i perspektiv af deres magtfuldkommenhed, deres tillidsbrud, deres uetiske adfærd og en selvfremstilling, der efterlader en med spørgsmålet om, hvem de egentlig er – eller ønsker at være.
Adgang til algoritmerne
Authors: Hjort Katrin
Published: August 2020

Da jeg forsvarede min doktordisputats i 2012, argumenterede jeg for, at fremtidens strid inden for velfærd ville dreje sig om ”Adgang til excellence”, dvs. kampen om adgang til den bedste omsorg, uddannelse og sociale sikring. I dag er denne forudsigelse blevet skrækindjagende aktuel.  Globale koncerner, nationer, institutioner og personer slås om adgangen til de mest effektive værnemidler mod Coronavirussen, herunder respiratorer, der kan forhindre, at vi lider kvælningsdøden.

Det var planlagt, at jeg 20. marts 2020 skulle holde en afskedsforelæsning, hvor jeg skulle tage udgangspunkt i den forelæsning, jeg holdt, da jeg i 2009 tiltrådte i mit professorat på Institut for Uddannelsesvidenskab på Syddansk Universitet. Ideen var, at jeg skulle beskrive udviklingen i dansk uddannelsesforskning i perioden 2010-2020. Men det blev ikke til noget, fordi universitetet blev lukket ned på grund af Corona-truslen. Vi blev konfronteret med en pandemi, der i værste fald bliver permanent, og som sætter helt nye vilkår for forskning og forskningsledelse.

Denne artikel forsøger at opsummere de tendenserne, vi i dag kan se inden for forskningsledelse og uddannelsesforskning. Nogle tendenser har manifesteret sig langsomt i løbet af de forløbne år. Andre er blevet radikaliserede på grund af krisen. Vi oplever på godt og ondt stærkere krav om anvendelsesorientering, en mere fremskreden digitalisering og en stærkere politisering af forskningen. Her vil jeg argumentere for, at striden i dag står om retten til at definere de algoritmer, der lægges til grund for håndtering af data. I Corona-krigen dukker foruroligende totalitære tendenser op. Mit håb er, at vi kan tage det så roligt, at vi kan bevare demokratiet.
Risikobaseret regulering som tillidsbevarende mekanisme i en uforudsigelig verden – rationaler, dilemmaer og paradokser
Authors: Henriksen Per
Published: August 2020

Den moderne verden er kompleks og dynamisk. Usikkerhed og uforudsigelighed råder, og det stiller store krav til den måde, vi forvalter de samfundsmæssige processer på. For i en usikker verden er tilliden til samfundets centrale institutioner og de systemiske organisationer af endnu større betydning, når vi skal opretholde et velfungerende velfærdssamfund. Alligevel oplever vi en række sager, f.eks. relateret til SKAT, sundhedssektoren og den finansielle sektor, der udfordrer vores indlejrede oplevelse af tillid til systemet. Men hvorfor får vi disse sager, og kan de undgås? En del af svaret ligger muligvis i det paradoks, at vi konsekvent søger at håndtere usikkerhed og uforudsigelighed ud fra strategier og principper, der er rodfæstet i en verdensopfattelse af forudsigelige kausale sammenhænge. Artiklen argumenterer for, at den opfattelse har konsekvenser, fordi årsags-virknings-sammenhænge ofte kendetegnes ved det stik modsatte, nemlig uigennemskuelighed og deraf, uforudsigelighed. Artiklen tager afsæt i paradigmet om risikobaseret regulering og kontrol som eksponent for  samfundsmæssige strømninger om rationel kausalitet, der har gjort risikostyring til et dominerende, men også tvetydigt svar på næsten alting. På den baggrund diskuteres 3 centrale udfordringer (strategisk ideologi, motiv- / praktik-kobling og risiko- / usikkerheds-tolkning), som risikobaseret regulering bør adressere for at afstemme intention med modernitetens natur. Den overordnede konklusion er, at ureflekteret tiltro til  risikobaseret regulering og kontrol som universel metodik, er en farefyldt vej for samfundskontrakten, fordi paradigmet i praksis ignorerer verdens diskontinuitet og betydningen af samme.
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
Authors: Jelic Aleksandra , Sekulic Milica , Stamenovic Marina , Ugrinovic Vukasin , Putic Slavisa
Published: August 2020

The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0?/90? and ?45?. The main tensile properties were determined as a basis for subsequent dynamic tests, in which permanent dynamic strength, crack growth, and crack growth rate in the material due to the action of fatigue load were assessed. Comparisons were made regarding the structure of the tested specimens. Samples were obtained from prepregs with a specific density of 1600 kg/m3. The tests were performed at room temperature. Scanning electron microscopy (SEM) was used to analyze the damage in the material during these tests, the mechanisms of their further damage progression and, the impact on the growth and growth rate of the initial crack in the material. The analysis of numerical results and micromechanical analysis confirmed the dominant role of the reinforcing structural element in the material in all performed tests. The obtained results are of great importance in the application of composite materials of such structures under different operating conditions and load regimes.

Published: August 2020

People with diabetes need routine health care to prevent potential exacerbations of diabetes and detect or prevent the development of additional chronic conditions that can worsen the course of diabetes. Using 2012 Medicare claims data from the State of Michigan for 443,932 beneficiaries with type 2 diabetes, we determined that there are differences between white and racial/ethnic minority people with diabetes in accessing any preventive care and in the amount of service used once they do access care, even after adjusting for the presence of multiple chronic conditions.

Testosterone (T) affects β-cell function in men and women. T is a prohormone that undergoes intracrine conversion in target tissues to the potent androgen dihydrotestosterone (DHT) via the enzyme 5α-reductase (5α-R) or to the active estrogen 17β-estradiol (E2) via the aromatase enzyme. Using male and female human pancreas sections, we show that the 5α-R type 1 isoform (SRD5A1) and aromatase are expressed in male and female β-cells. We show that cultured male and female human islets exposed to T produce DHT and downstream metabolites. In these islets, exposure to the 5α-R inhibitors finasteride and dutasteride inhibited T conversion into DHT. We did not detect T conversion into E2 from female islets. However, we detected T conversion into E2 in islets from two out of four male donors. In these donors, exposure to the aromatase inhibitor anastrozole inhibited E2 production. Notably, in cultured male and female islets, T enhanced glucose-stimulated insulin secretion (GSIS). In these islets, exposure to 5α-R inhibitors or the aromatase inhibitor both inhibited T enhancement of GSIS. In conclusion, male and female human islets convert T into DHT and E2 via the intracrine activities of SRD5A1 and aromatase. This process is necessary for T enhancement of GSIS.

Sign language is the communication that used by the deaf people. Sign language is also a form of accessibility for deaf people to be able to socialize with people around them. Deaf socialization with normal people in the society is not optimal because most of the people does not yet know sign language. Based on these problems, this study aims to develop an interactive media introduction to BISINDO sign language based on augmented reality for the community in supporting a society that is more inclusive of the deaf. This study uses a Research and Development (R&D) approach. The sample in this study was deaf people who participated in the Gerkatin Padang community, and people from various professions in the city of Padang. The data collection technique was carried out using a questionnaire and a focused group discussion technique. Based on the results of the collection of 100 respondents' perceptions data from the public towards sign language obtained: 1) the level of getting to know the community towards sign language is still low at 57%, 2) the level of skills using sign language is still low at 83%, 3) the importance level of sign language according the community is 81%, 4) The level of community needs to learn Sign Language is obtained by 88%, and 5) The level of selection of the right media for learning Sign Language, 74% of respondents choose media in the form of a smartphone application. The validity of the interactive media prototype introduction BISINDO sign language developed in terms of substance that is the suitability of sign language in the application obtained a validator rating of 89.33%, then in terms of the media obtained a validator value of 89.67%. It can be concluded that the interactive media prototype in the form of a smartphone application that was developed very well in terms of substance and media so that it is very feasible or valid to be used in the introduction of BISINDO sign language.

A explicação genética da Lei, como criador "suposto", que permite legitimar suas regras legais como devidamente obedecidas, como resultado de um contrato original e universalmente predicado, possibilita - apesar do que está declarado atualmente -, o suposição, irrestrita, de que todos devem - e querem ou devem querer - estar em conformidade com as regras e, nesse fato, conjecturar a legitimidade da autoridade. No entanto, sim, por um momento, essa suposição é considerada como o produto de uma mentira de protocolo, embora necessária, a própria certeza, baseada na improbabilidade dessa suposição, não é legítimo que todos interpretem a lei, arbitrariamente, imposta? talvez o mediador ainda não tenha o direito de esmaecer o conflito, que é a mediação em si, interpretando o interpretativo? e, talvez, não seja exatamente a ausência de segurança jurídica a razão pela qual o conflito não é tal, mas uma consideração natural da lei, condicionada por sua própria constituição?

Published: August 2020

It has been noted that zinc contamination is hazardous which induces researchers seek new means to overcome it. One of the methods is to employ sunflower plant to eliminate zinc in soil. However, there is insufficient information about zinc phytoremediation by sunflower Helianthus annuus in hydroponic system. Hence in this study, a 15-day experiment was conducted using zinc concentrations of 0, 10, 20, and 30 mg/L in a hydroponic system. The effects of zinc concentration on the plant growth (length of root, length of stem and number of leaf), zinc uptake and zinc translocation were evaluated. The findings showed that the plant growth was inhibited, where the zinc concentrations had affected the growth of the sunflower root, length and stem, and the zinc uptake significantly (p<0.05). It was also found that there was a significant variation of root length and zinc uptake in leaves within certain phases statistically (p<0.05). Then the translocation factor was found significant different for the time parameter but not the zinc concentrations (p<0.05). Therefore, this experiment concluded that the sunflower plant was highly tolerant to zinc and able to extract the zinc from contaminated environments. Lastly, this study showed that the sunflower is potential to phytoremediate zinc in a hydroponic system.

The structural, electronic and optical properties of nickel disulfide (NiS2) and iron (Fe)-doped NiS2 were computed by using first-principles calculations through the density functional theory (DFT) method. The Fe was used as a dopant element to understand the behavior and the key mechanism of Fe-doped NiS2 as a counter electrode in dye-sensitized solar cells (DSSC). The results indicated that the structural properties of the NiS2 as the cubic crystal structure with the space group Pa3 (205) (pyrite structure type) agree with experimental data. The density of states (DOS) of NiS2 and Fe-doped NiS2 shows a gapless bandgap due to Mott insulator behavior. As for optical properties, the optical absorption of NiS2 is shifted towards the infrared (IR) region when doping with Fe while the conductivity of Fe-doped NiS2 is slightly higher in conductivity. These optical properties show that Fe-doped NiS2 is good for photocatalytic activity and may provide an excellent electron charge transfer for a counter electrode in DSSC
Administration Of E-Invoicing Value Added Tax(Comparative Study between Indonesia and Australia)
Authors: Tenardi Riki , Putranti Titi Muswati
Published: August 2020

Technological changes in tax administration especially VAT have also changed the way tax authorities around the world implement e-invoice tax, one of which is Australia. The Ministry of Finance of the Directorate General of Tax (DGT) Indonesia responded to this in 2013 by creating a VAT administrative technology system called the Electronic Tax Invoice (e-Faktur). This study aims to determine the administration of Indonesian e-Faktur by looking at the Australian e-invoice as a benchmark and to find out the problems of e-Faktur in Indonesia after implementation. This research method is a qualitative method with techniques in the form of literature studies and in-depth interviews with informants. The results of this study are that the e-Faktur of the system in Indonesia is different from the understanding of the existing e-invoicing in the literature and the Australian state. Australian e-invoicing system neglects sending data in the form of digital data (PDF) and sending via email. E-Faktur was found to still have problems after its application such as access which was always problematic because of the network, the insecurity of VAT data, and the costs that still arise due to the application e-Faktur such as the still printing of documents and inefficiency. The conclusion from this study is that there are still fundamental differences between the administration of Indonesian and Australian e-invoice.
Influence of ageing on circadian rhythm of heart rate variability in healthy subjects
Authors: Accardo Agostino , Merlo Marco , Silveri Giulia , Del Popolo Lucia , Dalla Libera Luca , Restivo Luca , Cinquetti Martino , Cannatà Antonio , Sinagra Gianfranco
Published: August 2020

Background

The analysis of the circadian rhythm of heart rate variability (HRV) represents a relevant physiological tool to assess the vagal system. However, the influence of age (mostly >75 years) on HRV is not widely known.

Aims

The aim of this study was to evaluate the influence of age on HRV, particularly in the elderly and to identify a model of this relationship. The study was carried out by examining linear and nonlinear parameters extracted from HRV, including individuals over 75 years for which there is no research available.

Methods

Data from 140 healthy subjects were sex matched and divided into young (young group: 15–39 years old), adult (adult group: 40–64 years old) and senior (senior group: 65–90 years old) groups. 24-h Holter monitoring was used and several HRV parameters were extracted from time, and spectral and nonlinear analyses were examined.

Results

Time-domain parameters, mainly standard deviation of the NN interval (SDNN) and number of successive differences of intervals which differ by more than 50 ms, presented significant differences between the young group and the other two groups during the 24-h period, while normalized spectral parameters (LFn, HFn and low frequency/high frequency), as well as nonlinear parameters, mainly β exponent and fractal dimension, showed significant difference between the senior group and the other two groups. All these parameters showed a similar circadian rhythm with significant differences between the mean day and night values, especially in young and adult group cohorts. Moreover, a parabolic relationship between these parameters and age was highlighted with an opposite trend over about 60 years compared with younger people.

Conclusion

A progressive physiological autonomic imbalance is present in ageing. The inverse trend in the relation between HRV parameters and age found in the senior group could be mainly due to a faster fluctuation of RR. This should be considered when studying changes in the cardiac autonomic nervous control.
Correction of pes varus deformity in a Miniature Dachshund by true spherical osteotomy with a dome saw blade
Authors: Sellier Clément , Dosal Michael M. , Guthrie James W. , Fitzpatrick Noel
Published: August 2020

CASE DESCRIPTION

A 6-month-old male Miniature Dachshund was referred for examination and correction of a unilateral pes varus deformity.

CLINICAL FINDINGS

Clinical examination and diagnostic imaging revealed varus, procurvatum, and internal torsion of the distal aspect of the left tibia causing intermittent lameness.

TREATMENT AND OUTCOME

True spherical osteotomy performed with a dome-shaped saw allowed correction of the deformity in 3-D, and orthogonal internal plate fixation provided stabilization. No intraoperative or immediate postoperative complications developed. Outcome as judged by the clinician and the owners was satisfactory 2 weeks after surgery and excellent at each subsequent assessment. The patient remained free of clinical signs at the last follow-up 30 months after surgery.

CLINICAL RELEVANCE

To the authors’ knowledge, this case represented the first time a true spherical osteotomy was used to correct a pes varus deformity in a canine patient.
Disseminated pancreatic adenocarcinoma in an eclectus parrot (Eclectus roratus)
Authors: Le Roux Alexandre B. , Quesenberry Katherine , Donnelly Kyle A. , Donovan Taryn A.
Published: August 2020

CASE DESCRIPTION

A 15-year-old 0.412-kg (0.906-lb) sexually intact male eclectus parrot (Eclectus roratus) was evaluated because its owners found it lethargic and dyspneic at the bottom of its cage.

CLINICAL FINDINGS

The parrot was thin and had generalized muscle wasting, diffuse feather loss, pale mucous membranes, and melena. The coelomic cavity was distended and soft on palpation, with coelomic effusion suspected. Results of a CBC indicated leukocytosis with left shift heterophilia, including toxic heterophils, lymphopenia, and anemia. Plasma biochemical analyses revealed severe hyperamylasemia.

TREATMENT AND OUTCOME

Radiography revealed no evidence of a metallic foreign body but severe loss of coelomic detail, suggestive of a coelomic mass, coelomic effusion with coelomitis, or both. Ultrasonography and CT revealed severe accumulation of coelomic fluid; a large, heterogeneous, irregularly marginated, and moderately vascularized mass in the caudal aspect of the coelomic cavity; and multiple hepatic, coelomic, and pulmonary nodules. On the basis of a poor prognosis, the parrot was euthanized. Necropsy results confirmed exocrine pancreatic adenocarcinoma, with disseminated metastases in the liver, gastrointestinal tract, coelomic cavity, and lungs.

CLINICAL RELEVANCE

In birds, pancreatic adenocarcinoma is rarely reported but should be considered a differential diagnosis for hyperamylasemia, coelomic mass, coelomic effusion, or abnormal gastrointestinal signs, alone or in combination. Ultrasonography and CT can be useful in further evaluating such patients and should be considered in the diagnostic plan.
The Electrophoretic Pattern of Serum Proteins in Sheep with Naturally Acquired Gastrointestinal Nematode Infections
Authors: Nagy Oskar , Tóthová Csilla , Klein Róbert , Chovanová Frederika
Published: August 2020

The objective of this study was to describe the serum protein pattern in sheep with naturally acquired gastrointestinal parasitosis and to compare the distribution of protein fractions with the results obtained in animals with negative fecal examination results. Fecal and blood samples were taken from twenty-nine sheep positive for nematode eggs and twenty-four animals with negative results of fecal examination. Between the evaluated groups of sheep significant differences were noted in the relative mean values for all protein fractions and for albumin/globulin ratio (p<0.01 and p<0.001). The concentrations of total proteins showed no significant differences between both groups of sheep. The absolute mean values of albumin, α2-globulins and A/G ratio were significantly lower, the mean concentrations of α1-, β-, γ1- and γ2-globulins significantly higher in the nematode positive group of sheep (p<0.01 and p<0.001). In the nematode positive group the protein electrophoretic pattern showed a double α2-zone in three sheep and the γ-globulin zones were characterized by a diffuse higher broad and wide peaks. The presented results indicate that the gastrointestinal parasitic infections in sheep alter the distribution of serum proteins, and suggest their usefulness in animals with unchanged serum protein concentrations. The study brings new findings and extends the knowledge about the metabolic responses and consequences of gastrointestinal parasitic infections in sheep, particularly with regard to alterations in protein metabolism.
Small Intestinal Ganglioneuromatosis Accompanied by an Ulcer in a 13-Year Old Dog
Authors: Huber Doroteja , Gudan Kurilj Andrea , Hohšteter Marko
Published: August 2020

Ganglioneuromatosis is a rare disorder characterized by hyperplasia of intestinal ganglia including myenteric plexus and enteric nerve fibers. This disorder is generally described in children, but sporadic cases have also been described in adults. Most human cases arise in the colon and rectum. The disorder has also been described in dogs, mostly juveniles, but rarely in mature dogs with the oldest dog reported with this change being 9 years old.

We report the first case in an older dog from Croatia. A 13-year old female, mixed-breed dog had a history of diarrhea and weight loss. Ultrasound revealed focally-extensive markedly thickened small intestine. The changed part of the intestine, measuring 7 mm x 20 mm, was removed on laparotomy and delivered for histopathologic examination. Grossly, the intestine showed circumferential expansion of the intestinal wall, which was whitish in color. Microscopic findings included diffuse hyperplasia of the myenteric and submucous plexus. Focally in the affected tissue a subacute ulcer was evident, which was probably not the cause of intestinal signs, as it presented a localized lesion, while ganglioneuromatosis was a diffuse change in the affected tissue.

So far, ganglioneuromatosis was reported in young dogs, rarely in adult dogs. Our report shows that ganglioneuromatosis can also be encountered in older dogs. Although the lesion presents a rare finding, it should be listed as a differential diagnosis in dogs where infectious and neoplastic etiology has been ruled out as cause of diarrhea.
Optical soliton solutions to a (2+1) dimensional Schrödinger equation using a couple of integration architectures
Authors: Çankal Pelin Doğan , Yaşar Emrullah
Published: August 2020

In this work, we consider a (2+1) dimensional nonlinear Schrödinger system which appears in the theory of nonlinear optics and describe transmission of the optical pulses in optical fibers. We attain certain special type traveling wave solutions of the under investigated model by help of finite series expansion and auxiliary differential equations. In this manner, we exploit exp(−ϕ(ε)) and modified Kudryashov approaches as solution procedures. Moreover, we make tanh ansatz because of the being even order of the reduced ordinary differential equation. The obtained solutions are in the form of dark soliton, combined soliton, symmetrical Lucas sine, Lucas cosine functions, and periodic wave solutions. We present also some graphical simulations of the solutions corresponding to values of parameters which leads to a better understanding the phenomena.

Authors: Busovikov V.M. , Sakbaev V.Zh.
Published: August 2020

We study the class of finite additive shift invariant measures on the real separable Hilbert space E. For any choice of such a measure we consider the Hilbert space ℋ of complex-valued functions which are square-integrable with respect to this measure. Some analogs of Sobolev spaces of functions on the space E are introduced. The analogue of Gauss theorem is obtained for the simplest domains such as the rectangle in the space E. The correctness of the problem for Poisson equation in the rectangle with homogeneous Dirichlet condition is obtained and the variational approach of the solving of this problem is constructed.

Several methods and materials are used in modern restorative dentistry for anterior dental lesions treatment. The desired aesthetic outcome can be obtained only with the correct treatment method correlated to case particularities. Sometimes, subjective and unrealistic approaches lead immediately or in time to undesirable dental restorations. The aim of the present paper is to evaluate the statistic distribution of aesthetic anterior dysfunctions detected on 425 patients from both genders that had restorative treatment during a period of 10 years. For each patient, there has been conducted an initial clinical examination and a photographic documentation was made. Also, each patient was asked to submit a questionnaire regarding his dental history. The results of the study represented the foundation for the discussions regarding the causes that led to aesthetic dysfunctions. The conclusions indicated that all errors that conducted to an initial failure of treatment are only connected with the medical decisions made by the dentist.

Myiasis is the infestation of live vertebrates with arthropod larvae of the order Diptera. The increase in the number of tourists in endemic areas, with the appearance of new cases in risk-free geographical areas, has increased the interest of doctors in knowing the insects that cause myiasis. The most common cases of myiasis are found in tropical and subtropical areas, the temperate zone being of interest in the warm season. In dermatological practice, there are cases of skin myiasis, especially at the level of skin ulcers. The appearance of ulcers myiasis is favoured by the poor socioeconomic status, poor hygiene conditions or associated debilitating general pathologies. Performing a correct treatment of ulcers is the main factor in preventing the larval infestation of ulcers.

Congenital heart diseases are an important cause of mortality and morbidity in pedatric patients. Fallot Type Double outlet right ventricle is a rare heterogenous congenital heart disease characterized by a complex group of lesions similar with Tetralogy of Fallot. Surgical approach depends on the anatomy of associated lesions, therefore in order to perform a successful correction, a careful review of the anatomy and a detailed diagnostic is needed due to complexity of intracardiac anomalies. The main diagnostic tool used nowadays for the diagnosis of double outlet right ventricle is echocardiography exam, a non-invasive examination that can provide information about anatomical features, but it will not allow the full description of the coronary anatomy. Therefore, preoperative assessment should include, extensive imaging assessment (echocardiography exam, angio-CT exam) for a correct management of surgical strategy prior to surgical correction.

Authors: Laslo Alexandru
Published: August 2020

Due to the changes in major trauma epidemiology, the management of thoracoabdominal trauma evolved in time. The thoracoabdominal major lesions were treated in the past by emergency laparotomy or tocachotomy. The morbidity associated with nontherapeutic laparotomies or thoracotomies lead to an increase of using conservative ways of treatment. We accomplished a retrospective study in which we included 234 patients, all of them diagnosed with thoracoabdominal trauma who were hospitalized in the General Surgery Ward. The objective of this study is to determine whether there is a correlation between the value of hematocrit and hemoglobin at patient admission and the values at discharge, in patients who required blood transfusion during hospitalization.

Published: August 2020

Introduction: Indication of primary pelvic exenteration, without previous radiotherapy, is questionable in advanced stages of gynaecological malignancies.

Materials and Methods: 24 patients who underwent primary pelvic exenteration for pelvic malignancies were studied retrospectively. The indications were cervical (n=17), vaginal (n=4), bladder (n=2) and endometrial cancer (n=1).

Results: According to the type of exenteration, 14 were anterior and 10 total. Relying on the resection lines in relation with levator ani muscles, 14 were supralevatorial and 10 infralevatorial, of which five involved vulvectomy. Early complications occurred in 7 patients with 1 perioperative death.

Conclusions: Primary pelvic exenterantion as first line therapy for advanced gynaecological malignancies can lead to long-term survival and it can even be curative in suitable selected patients. Still, postoperative complications are frequent, which can be lethal.

Published: August 2020

This paper is focused on exploring and utilizing the acoustic emission and its behaviour during surface roughness measurement. Surface quality or coating properties significantly affect the reliability and durability of operations. Three samples were selected for an experiment to demonstrate the possibility of measuring the roughness of surface textures by means of acoustic emission method (AE). These samples were made of the following materials: sample A2 – EN 54SiCr6 steel formed in water, austenitized at 850 °C for 20 minutes, sample A3 – non-heat-treated spheroidal graphite cast iron, and sample B5 – abrasion resistant austenitic manganese steel. The surfaces were subjected to the same surface treatments (roughness Ra = 1.6–3.2 μm) and measured under the same conditions. All possible measurements were measured on both x- and y-axes. Final results are presented graphically. The measured AE values showed a visible effect in the AE signals due to the lack of surface roughness.
Design and Development of a Novel Mechanism for the Removal of False Selvedge and Minimization of its Associated Yarn Wastage in Shuttleless Looms
Authors: Qureshi Sajid Ahmed , Ramesh Kumar M. , Prakash C.
Published: August 2020

A novel mechanism for the elimination of false selvedge in rapier looms was successfully designed and developed, which functions to grip the protruding weft ends after each pick insertion during the weaving process, with subsequent cutting and suction of the protruding ends. The task is otherwise, presently performed by the formation of dummy or false selvedges in the fabric, requiring additional yarn other than that required for the actual fabric. A significant amount of yarn is wasted to form false selvedges, as they are removed and disposed as hard waste post weaving, which consequently increases the cost of fabric and narrows the profit margins. The developed mechanism was successfully installed and commissioned on an indigenous rapier loom leading to a reduction in the amount of hard waste otherwise generated, without affecting the normal functioning of the loom and the weaving process. The amount of reduction in hard waste was estimated and the quality of fabric manufactured before and after the installation was tested and analyzed.

Authors: Perrotta Andrew S. , Warburton Darren E.R.
Published: August 2020

Study aim: This investigation examined the cardiac vagal modulation-to-vagal tone ratio and its utility to represent the dose response to accumulated exercise stress in intermittent team sport.

Material and methods: Fourteen international calibre female field hockey players training as part of a national team were participants over a three-week period. Exercise stress was expressed through cardiovascular strain using heart rate (HR) dynamics and was quantified as a training load (AU) and time spent exercising above anaerobic threshold (min). Cardiac autonomic activity was examined using heart rate variability; R-R intervals (ms) were collected immediately upon awakening throughout each weekend. The square root of the mean squared differences of successive R–R intervals were individually calculated, and log transformed prior to being averaged (Ln rMSSD) along with the corresponding mean R-R interval length. Multiple linear regression analysis examined the association between cardiac autonomic activity and indices of accumulated exercise stress.

Results: Significant inverse associations (95% CI) between the Ln rMSSD:R-R ratio and both training load [r = –0.48 (–0.70: –0.18), p = 0.012] and time spent exercising above anaerobic threshold [r = –0.51 (–0.72 : –0.22), p = 0.006] were observed. The association between mean R-R interval length and Ln rMSSD was not significant [r = 0.05, p = 0.950].

Conclusion: The current study demonstrated high intensity exercise, as defined through time spent above anaerobic threshold, displayed a stronger association with the Ln rMSSD:R-R ratio compared to a HR-derived training load when examining the dose response to accumulated intermittent exercise.
Effect of exogenous transcription factors integration sites on safety and pluripotency of induced pluripotent stem cells

Induced pluripotent stem cells (iPSCs), generated from somatic cells, not only possess similar characteristics with embryonic stem cells (ESCs), but also present more advantages than ESCs in medical applications. The classical induction method that utilizes the integration of exogenous genes into chromosomes may raise the potential risk of the safety of iPSCs. To investigate the potential correlation between the integration sites of exogenous transcription factors (TFs) and iPSCs’ pluripotency and safety, the integration of exogenous genes in three iPSC lines, which met the golden standard of murine developmental assay (tetraploid complementation), were analyzed. Twenty-two integration sites of exogenous TFs were identified by nested inverse polymerase chain reaction (iPCR) and 39 flanking genes’ functions were analyzed by gene ontology (GO). In the 22 integrated sites, 17 (77.3%) were located in the intergenic regions and the remainder were located in introns far from the transcription start sites. Microarray analysis of the flanking genes in these cells showed that there was no distinct difference in expression levels between the iPSCs, ESCs and mouse embryonic fibroblast (MEF), suggesting that the integration of exogenous TFs has no significant influence on the expression of flanking genes. Gene ontology analysis showed that although most of the flanking genes were housekeeping genes, which were necessary for basic life activity, none of these 39 flanking genes have correlation with tumorigenesis or embryogenesis, suggesting that the integration sites hold low risk of tumorigenesis.

Spondyloarthropathies (SpAs), are a group of chronic inflammatory diseases with a number of genetic, physiopathological, clinical and radiological features. Ankylosing spondylitis (AS) is the most common type of spondylo-arthropathies, and >90.0% of patients with ankylosing spondylitis are human leukocyte antigen-B27 (HLA-B2 7)-positive. In recent years, non-HLA genetic factors have been reported to have an effect on ankylosing spondylitis. MicroRNAs (miRNAs), are endogenous non coding RNA molecules containing 18-23 nucleotides that play a role in the post-transcriptional regulation of gene expression. In this study, we aimed to determine the expression levels of miRNAs associated with T- and B-cell differentiation/stimulation in peripheral blood mononuclear cells and their relationship with the etiology of the AS in patients and healthy controls. In a molecular study, peripheral blood mononuclear cell isolation, and total RNA isolation were performed first. In the second step, cDNA synthesis and quantitative real-time PCR (qPCR) expression analysis were completed. Ultimately, in the patient and control group, the expression levels of miR-142-5p and miR-143 were found to be significantly different (p <0.05). According to current knowledge, miR-142-5p andmiR-143 expressions were found to be important for those diseases that share similar etiology with AS. We suggest that miR-142-5p and miR-143 may play a role in the pathogenesis, especially miR- 142-5p may be a potential biomarker and a target molecule for the treatment.
Determinants of audit fees: Evidence from Poland
Authors: Rewczuk Karol , Modzelewski Piotr
Published: August 2020

Unlike many studies concerning audit fees in Western Europe or the United States, literature concerning this kind of research is very limited in Central and Eastern Europe. This study aimed to show what factors shape audit fees in Poland. It was conducted based on data collected from the financial statements of 111 companies listed on the Warsaw Stock Exchange in 2018. The study used a linear regression model to verify the determinants of audit fees. The research results indicate a positive relationship between audit fees and company size, measures of complexity (in addition to the ratio of inventories and receivables to total assets) and the fact that a company is audited by the ‘Big Four’ accounting firms.
