Background: Anemia is an important comorbidity in under-five children with severe acute malnutrition (SAM). The data on evaluation of SAM are limited. Aim: This study was done for analysis of incidence and types of anemia prevalent in SAM children. Materials and Methods: It was a hospital-based prospective observational study conducted from July 2017 to December 2018. A total of 260 children of age <5 years and who were confirmed cases of SAM were included in the study. A detailed demography and data regarding anemia and related variables hemoglobin, mean corpuscular volume, peripheral smear, serum ferritin, Vitamin B12, and folic acid levels, were recorded and analyzed. The data were entered into MS-Excel sheet and analysis was performed using SPSS version 21.0. Results: About 95% of anemia prevalence was found among children with SAM and most cases were of nutritional anemia (81.79%). About 54.33% of the children had mild anemia, with 79.75% had iron deficiency as the most common cause, followed by Vitamin B12 and folic acid deficiency. Conclusion: The high prevalence of anemia suggests that it may contribute as a causal factor for hospitalization in severely malnourished children.

Authors: Moreno Gonzalo Guillermo , Peña César Augusto , Gualdron Oscar Eduardo
Published: July 2020

Structure and mechanism analysis often involves the use of advanced simulation programs, which are not always available to users. The Davies method has proven to be an efficient and easily applied tool in this type of analysis, allowing the obtaining of the stresses present in the links and the necessary torque to keep the device in optimal operative conditions. All these standards will set the foundations for the development and proper design of the mechanism. Taking into account the afore mentioned, this article describes in detail the use and applications of the Davies method for stress and kinematic analysis of a landing gear.
Regaining Iceland for the Catholic Church in the mid-19th Century
Authors: Guðmundsson Birgir , Meckl Markus
Published: July 2020

In the late 1850s, the Church of Rome sent missionaries to Iceland; to begin with, a Catholic priest and an assistant. The proclaimed purpose of their stay was to service the thousands of French seamen that were fishing for cod in Icelandic waters. However, although the official and most visible purpose of the Catholic mission was to attend to the French sailors, the mission was also meant to reclaim Iceland to the Catholic faith. This essay contains the first account of the experiences of father Bernard, the priest who was in charge of this mission.
Winning the War of the World

The air, soil and water cumulatively degrade and disappear; the climates and oceans destabilize without connection; species become extinct at a spasm rate across continents; pollution cycles and volumes rise endangering life systems on all planes in synergistic despoliation; the world’s forests, meadows and fisheries are cumulatively destroyed by the profit drivers of globalization; food pollinators, songbirds, coral reefs and large animals crash in unconnected response; public sectors and services are defunded and privatized as tax evasion by the rich multiplies; the global food system produces more and more disabling junk and wastes; non-contagious diseases multiply to the world’s biggest killer; the global financial system issues money out of control while collapsing in productive investment; the vocational future of the next generations is erased across the world; official lies and corruption are normalized as public relations. All the trends are one-way, degenerate, and undeniable.
The Sardinian Literary Spring: An Overview. A New Perspective on Italian Literature
Authors: Broccia Michele
Published: July 2020

This article aims at presenting today’s Sardinian literary scene and how some novelists (Sergio Atzeni, Giulio Angioni, Salvatore Mannuzzu, Salvatore Niffoi, Marcello Fois, Giorgio Todde, Milena Agus, Francesco Abate, Flavio Soriga and Michela Murgia), during the last few decades, drawing their narrative subjects directly from the regional and local culture, are contributing to a new development in Italian literature. These authors’ novels often contain references to Sardinian linguistic, social, anthropological and historical facts. Their success has led literary critics to talk about a Sardinian Literary Spring or Sardinian Nouvelle Vague, i.e. a literary phenomenon, which is the expression of a deep-rooted Sardinian identity.

Experimenting with Psychotherapy
Authors: Björnsson Andri Steinþór
Published: July 2020

There are two major shortcomings in current psychotherapy outcome research: The standards that are used to evaluate psychotherapy (especially the way control conditions are set up in outcome research) are often not acceptable, and non-specific factors have been largely neglected, in part because of the “psychological placebo” metaphor. I argue that theories of psychotherapy need to specify further the role of non-specific factors in the development and maintenance of different disorders, and how non-specific treatment factors can be made to be more effective in therapy. This may be the major front in the future of psychotherapy research.
On the Range or Scope of [Moral] Action
Authors: Barden Garrett
Published: July 2020

The range or scope of [moral] action is the range or scope of deliberate action. A deliberate action is chosen. Some choices are, for various reasons, considerably more important than others – most will agree that the decision whether or not to get married is more important than whether or not or where to go on holiday – but no choice is outside the moral realm, and no choice, as Aristotle already made clear, is made in the abstract. All actual choices are made in the prevailing circumstances as they are understood by the person choosing. There are no abstract and no non-moral choices.
What is Morality? Pascal’s Heartfelt Answer
Authors: Baruchello Giorgio
Published: July 2020

Despite his enduring fame as a scientist and a thinker, Blaise Pascal’s moral philosophy has received very little attention by modern Anglophone ethicists, who have written instead endless volumes on the epistemology of his wager—itself a piece of apologetics and an early example of game theory. They have labelled Pascal a ‘philosopher of religion’ and pretty much left him there, as marginal as religion itself seems to be these days. Yet, Pascal did have a moral philosophy of his own and one that can help us answer the question ‘what is morality?’ from the perspective of lived personal experience. It is not an easy one to detect, for it is scattered across his unsystematic maxims, short reflections and aphorisms, themselves scattered across a number of differing manuscripts. Reconstructing and outlining it is the chief aim of my paper.

Background: Problems frequently occur from hair extraction are low concentration and impurity of DNA.

Methods: Hairs from 30 postmortem cases were collected. In each case, 5 and 10 hair roots were extracted DNA by Phenol/Chloroform/Isoamyl alcohol. The amount and purity of DNA (A260/280) were detected by NanoDrop spectrophotometer. The quality of DNA was examined using polymerase chain reaction (PCR). Amount of DNA was analyzed compared with gender, age, and manner of death.

Results: The amount and purity of DNA extracted from 10 hair roots were slightly better than 5 hair roots (P > .05). The mean (range) of DNA concentration was 200.4 (35.2 - 799.6) ng/µL from 10 hair roots vs 148.2 (21.7 - 571.5) ng/µL from 5 hair roots in 30 µL volume whereas the mean (range) of A260/280 was 1.61 (1.31 - 1.99) in 10 hair roots vs 1.54 (1.32 - 1.90) in 5 hair roots. The results from NanoDrop showed no difference among various gender, age, and manners of death.

Conclusions: DNA can be extracted from hair by Phenol/Chloroform/Isoamyl alcohol. The quantity and quality of DNA were good enough for personal identification by PCR. DNA extracted from 10 hair roots is better than 5 hair roots.

Published: July 2020

Cardiovascular disease (CVD) is the leading cause of death among patients who have chronic kidney disease (CKD). Nowadays, CKD per se is considered one of the coronary heart disease (CHD) risk equivalents. Apart from traditional CVD risk factors, there are several possible determinants for CVD in patients with CKD, for example, uremic toxins, increased inflammatory stage, abnormal bone mineral metabolism, and positive calcium balance. In this narrative review, we offer a summary of the extensively studied biomarkers for CVD in patients with CKD, including uremic toxins (p-cresol, indoxyl sulfate, and advanced glycated end products), and a novel indicator of arterial stiffness, cardio-ankle vascular index (CAVI), which is an independent prognostic predictor for CVD. For the uremic toxins, we reviewed their metabolisms, particularly, how the reduced renal function in CKD patients affect their clearance and their clearance with dialysis. Also, we pay attention to the recent evidence on how those uremic toxins contribute to CVD and their clinical associations. We do not include the possible treatment targeting at those uremic toxins. As for the novel indicator of arterial stiffness, we reviewed the clinical application of CAVI in comparison to the standard indicator for arterial stiffness, pulse wave velocity.
Vulnerabilities Mapping based on OWASP-SANS: A Survey for Static Application Security Testing (SAST)
Authors: Li Jinfeng
Published: July 2020

The delivery of a framework in place for secure application development is of real value for application development teams to integrate security into their development life cycle, especially when a mobile or web application moves past the scanning stage and focuses increasingly on the remediation or mitigation phase based on static application security testing (SAST). For the first time, to the author’s knowledge, the industry-standard Open Web Application Security Project (OWASP) top 10 vulnerabilities and CWE/SANS top 25 most dangerous software errors are synced up in a matrix with Checkmarx vulnerability queries, producing an application security framework that helps development teams review and address code vulnerabilities, minimise false positives discovered in static scans and penetration tests, targeting an increased accuracy of the findings. A case study is conducted for vulnerabilities scanning of a proof-of-concept mobile malware detection app. Mapping the OWASP/SANS with Checkmarx vulnerabilities queries, flaws and vulnerabilities are demonstrated to be mitigated with improved efficiency.

Published: July 2020

In recent years, there have been a rise in the number of problems in the existing traffic management system particularly in the developing countries such as Bangladesh, India and Vietnam. Due to this, many accidents have occurred every now and then. Violating the traffic rules such as unpermitted change of lanes and over speeding are the two main reasons for increased number of accidents. In this paper, an attempt is made to solve the problem using Raspberry-pi and OpenCV contour detection technology. A prototype device has been developed to solve the problems regarding lane-based rule violations. The device will be installed in traffic surveillance cameras which will be connected to the metropolitan traffic servers. The device will communicate with the server via Gigabit Ethernet. It will also increase the time efficiency and reduce the manual monitoring cost. Moreover, it will help the traffic management department to find the person responsible for traffic rule violation and assist them to apply the laws strictly. The main contribution of this article is to develop a device that will detect any kind of unpermitted lane changes by any vehicles and identify the license plates. The proposed model has about 80% accuracy according to our evaluation.

Published: July 2020

Introduction: Loss of balance causes the sensation of vertigo. Balance is maintained by vestibular afferent from labyrinth, eyes and proprioceptors and their central integration. For diagnosis of vertigo, along with history different vestibulometric tests can be done to identify the specific anatomical part that is involved.
Material and methods: A cross sectional study was done among 82 patients who did video Head Impulse Test (vHIT) and among 75 patients who did Vestibular Evoked Myogenic Potential (VEMP) test at AudiovestibularCentre(AVC) at Bangladesh ENT Hospital Ltd. during the period from April 2018 to September 2019.
Results: Age range of the sample was 16 to 80 years. Among the 82 patients who did vHIT 62(75.6%) had abnormality in either Semi Circular Canal. Among 75 patients who did VEMP 27(36%) were detected to have abnormality in either in saccule or utricle.
Conclusion: For diagnosis of cause of vertigo the appropriate test for individual part of vestibule is essential. vHIT and VEMP are two tests which are complementary to each other in explaining common peripheral causes of vertigo.

Langerhans cells histiocytosis (LCH) or histiocytosis-X is a rare group diseases that includes three overlapping diseases of Hand-Schuller-Christian disease (HSC), Letterer-Siwe disease (LS)and Eosinophilic granuloma(EG). It results from clonal proliferation of histiocytes having similar morphology and immunophenotype to Langerhans cells in skin and mucosa Though head and neck manifestation is common, isolated simultaneous bilateral temporal bone Langerhans Cell Histiocytosis is an extremely rare presentation. Having same otological menifestations, high resolution CT scan is advocated for early identification and differentiation of LCH from other common conditions such as mastoidits,otitis externa ,chronic suppurative otitis media. Diagnosis of LCH is confirmed by biopsy and immunohistochemical staining of S-100 protein and or CD1a antigen. Chemotherapy is main mode of treatment.The prognosis is worse when presenting age of children is younger than 2 years.

Authors: Kassa Getachew , Feyissa Tileye
Published: July 2020

This study was aimed to investigate salt tolerance of two grapevine cultivars, ‘Chenine Blanc’ and ‘Canonannon’ through in vitro propagation on medium containing different concentrations of NaCl. Single-node shoots were cultured on MS with 1.0 mg/l BAP in combination with 0.1 mg/l IBA and containing 0.25, 0.50, 0.75, 1.00 or 1.50% NaCl. NaCl free medium was used as control. Shoots of both cultivars were cultured on the same MS containing 0.25, 0.50, 0.75 or 1.00% CaCl2 to reduce hyperhydricity. The shoots were transferred to rooting medium followed by acclimatization in greenhouse. Number and length of shoots and roots, number of leaves and nodes, length of nodes, fresh and dry weight of roots and shoots decreased significantly in consistent trend as the concentration of NaCl increased. ‘Canonannon’ cultivar was found to be significantly more tolerant to NaCl than ‘Chenine Blanc’ in all parameters. The lowest percentage of hyperhydric shoots were obtained on medium containing 0.25% CaCl2. Therefore, ‘Canonannon’ cultivar can be planted in relatively saline soils as it is more tolerant to salt than ‘Chenine Blanc’.

Development of an in vitro Callus Induction Protocol and Shoot Proliferation for Selected Jatropha (Jatropha curcas) Accessions
Authors: Fufa Hundessa , Daksa Jiregna
Published: July 2020

The present study was undertaken to establish a protocol for in vitro callusing of three Jatropha accessions, namely Metema, Adami Tulu and Shewa Robit from leaf explants. The medium supplemented with combination of 4.44 μM BAP and 4.52 μM 2,4-D resulted in maximum percentage of callus (100%) formed for all accessions. The maximum shoot regeneration (66.67%) from callus with 10.13 number of shoot was obtained from Shewa Robit in MS medum fortified with TDZ (2.27 μM ) and IBA (0.49 μM ). The presence of TDZ in the shoot regeneration medium has greater influence on the induction of adventitious shoot buds, whereas MS supplemented with BAP alone and combination with IBA did not induce shoot regeneration from callus culture. The results obtained in the present study would facilitate the high callus induction and regeneration responses in Jatropha for its improvement using biotechnological tools.
