A rare triad of appendiceal diverticula, appendiceal carcinoid, and colonic diverticula
Authors: Kim Sunyoung , Makkapati Shreya , Modukuru Venkat , Wallack Marc
Published: March 2022

Appendiceal diverticulosis is a rare finding associated with appendiceal
neoplasms. Both can masquerade as appendicitis and are overlooked in
differentials of right upper quadrant pain. Carefully examining the
appendectomy specimen for diverticula can aid in the risk assessment of
appendiceal carcinoid tumors and for the optimal treatment before cancer
progression.

A targeted capture approach to generating reference sequence databases for chloroplast gene regions
Authors: Foster Nicole , Dijk Kor Jent van , Biffin Edward , Young Jennifer , Thomson Vicki , Gillanders Bronwyn , Jones Alice , Waycott Michelle
Published: March 2022

Metabarcoding has improved the way we understand plants within our
environment, from their ecology and conservation to invasive species
management. The notion of identifying plant taxa within environmental
samples relies on the ability to match unknown sequences to known
reference libraries. Without comprehensive reference databases, species
can go undetected or be incorrectly assigned, leading to false positive
and negative detections. To improve our ability to generate reference
sequence databases we developed a targeted capture approach using the
OZBaits_CP V1.0 set, designed to capture chloroplast gene regions
across the entirety of flowering plant diversity. We focused on
generating a reference database for coastal temperate plant species
given the lack of reference sequences for these taxa. Our approach was
successful across all specimens with a target gene recovery rate of 92%
which was achieved in a single assay (i.e., samples were pooled), thus
making this approach much faster and more efficient than standard
barcoding. Further testing of this database highlighted 80% of all
samples could be discriminated to family level across all gene regions
with some genes achieving greater resolution than others – which was
also dependant on the taxon of interest. Thus, we demonstrate the
importance of generating reference sequences across multiple chloroplast
gene regions as no single loci is sufficient to discriminate across all
plant groups. The targeted capture approach outlined in this study
provides a way forward to achieve this.
Temporary Application of a Tarsal Arthrodesis Plate as a Postoperative Immobilization Technique in Common Calcaneal Tendon Injury Repair in Dogs: A Pilot Study
Authors: Lee Cole Grayson
Published: March 2022

Objective: To determine if the temporary application of a pantarsal arthrodesis plate would provide adequate postoperative tarsal immobilization after calcaneal tendon repair and to identify complications compared to an established technique. Study Design: This was a single institution retrospective pilot study. Medical records of dogs from January 2008 through September 2019 that presented for common calcaneal tendon injury and underwent surgical repair were reviewed. Exclusion criteria included cases that had incomplete medical records or had insufficient follow up. 17 calcaneotibial (CT) screw and 10 temporary tarsal arthrodesis plate (TTAP) cases were included in the final analysis. Data collected included signalment, pertinent history, injury type, surgical technique, duration of postoperative immobilization, major postoperative complications that warranted a second procedure, and follow up time. Results: The major complications in the CT screw group were tendon re- injury (n=5), surgical site infection (n=1), and tendon laxity (n=1). The major complication in the plate group was tendon laxity (n=1). The median follow up time after initial surgery was 171 (range 36-1670) and 185 (range 57-567) days for the CT screw and TTAP groups, respectively. Conclusion: The results from this pilot study suggest that a TTAP is an acceptable method for postoperative immobilization after primary calcaneal tendon repair. Further research is warranted to validate this procedure.

“Bring Back Our Money”: The Legality of Returning Assets and Wealth Acquired by African Leaders Through Corruption to African States
Authors: Ackon Perry , Dagadu Palmer Prince , McDave Kujo Elias
Published: March 2022

In the wake of corrupt activities by some leaders in Africa and the world at large, their extravagant assets in foreign lands and fattened offshore accounts after their prosecution has become the focus of recent discussions. The success of the modern legal framework has made it possible for corrupt leaders to be arrested and prosecuted.
This has resulted in assets of such leaders being seized and accounts being frozen by legitimate court orders. This paper highlights the legal procedures that govern the return of assets and wealth acquired through corrupt means on both the international and domestic fronts. Not doing away with the challenges and hindrances to this honourable act of returning the wealth of mostly developing nations to them, the paper makes use of relevant case studies as it addresses the hurdles to this effect in modern contexts.
It however concludes that this phenomenon should not be an issue for only developing countries but should also be of keen interest to developed nations as well. The pursuit of globally sustained development is not a race for some but for all. With all major stakeholders playing their part, the embezzled funds which has deprived the victimized states of substantive development shall be returned.

Authors: Karadeniz Yasin
Published: March 2022

Eksiltme, konuşma ya da yazı dilinde bir sesten bir cümle düzeyine
kadar gidebilir. Konuşma veya yazı dilinde eksiltme; en az çaba yasasının, bir başka deyişle enerjide tasarrufun bir sonucudur. Dünyada “Zipf
yasası” olarak da bilinen en az çaba yasası; tekrara düşmeden, sözü fazla
uzatmadan, ekonomik ama karşıdaki kişinin anlayabileceği en etkili şekilde dili kullanmaktır. Bu nedenle konuşur ya da yazar, kullandığı dilin
kuralları çerçevesinde çeşitli eksiltmeler yapabilmektedir.
Konuşma dilinde sıklıkla karşılaşılan eksiltme örneklerinin, bazı
durumlarda yazı dilinde de kullanıldığı görülmektedir. Konuşma dilinde
eksiltmenin belirli bir kuralı ya da düzeni olmadığı için yapılan incelemelerde konuşma dilinin temel alınması doğru sonuçlar vermeyebilir. Bu
nedenle eksiltmeyle ilgili çalışmalarda daha çok yazılı metinler kaynak
olarak seçilmektedir. Bu çalışmada da konu, Özbek Türkçesi eserlerinden
seçilmiş bazı metinler çerçevesinde ele alınmıştır.
Çalışmada, eksiltme yapılarının Özbek Türkçesindeki kullanım biçimleri üzerinde durulmuştur. Bundaki amaç, genel olarak eksiltmenin
Özbek Türkçesindeki oluşum biçimlerini göstermektir. Bu sebeple öncelikle eksiltme terimi konusunda Türkiye ve Özbekistan dil bilimindeki görüşler verilmiş, bu konuda dile getirilen diğer terimler gösterilmiş,
eksiltme konusuyla doğrudan ilişkili olan ve eksiltmenin oluşum sebebi
kabul edilen en az çaba yasası üzerinde durulmuştur. Daha sonra Özbek
Türkçesinde eksiltme konusu; edebȋ eserlerden seçilen metinlerden hareketle ek, kelime, kelime grubu ve cümle düzeyinde incelenmiştir. Böylelikle konu, bütüncül bir yaklaşımla değerlendirilmiştir.
“SANCHO NUN SABAH YÜRÜYÜŞÜ”NÜN RUS BİÇİMCİLİĞİ AÇISINDAN ELEŞTİRİSİ
Authors: Gürgün Hasan
Published: March 2022

Rus biçimciliği; bir eserin edebîliğini, eserden hareket ederek kendine özgü kavramlarla ortaya koymaya çalışan nesnel bir eleştiri yöntemidir. Bu eleştiri yöntemine göre edebîlik; şiir ve şiire yakın türlerde
“alışılmışın kırılması”, roman ve romana yakın türlerde ise “süje”nin
kurgulanışı ile sağlanır. Alışılmışın kırılması; bir metinde, günlük dilde
kanıksanan yapılardan farklı dilsel formların oluşturulmasıdır. Süje ise
olay ve durumların gerçekte olması beklenenden farklı şekilde organize
edilmesidir. Alışılmış bir yapı okur tarafından otomatik bir şekilde algılanır, bu yüzden de yapı fark edilmez hâle gelir ve beklenen edebî etki
ortaya çıkmaz. Otomatik algılamanın zararlı etkisi ancak bu olumsuz durumun ortadan kaldırılmasıyla yani alışılmış yapının farklılaştırılmasıyla
aşılabilir. Temel olarak bu iki düzenleme, metnin otomatik algılanmasının
önüne geçip onu algılanır hâle getirir ve edebîliği sağlar.
Haldun TANER, Türk hikâyeciliğinin öncü ve önemli bir yazarıdır.
Modern hikâye tekniklerini ustaca kullanan yazar, edebîliği eserlerinde

Ovidio y Lorenzo Valla, dos autores separados por catorce siglos, escriben sobre el amor trágico. Sus narraciones comparten argumento y protagonistas: dos jóvenes adolescentes que deciden vivir su amor en libertad, lejos de imposiciones, y terminan en fatal desenlace. Ovidio en sus Metamorfosis incluye la leyenda de Píramo y Tisbe; a su vez, Lorenzo Valla en Historiarum Ferdinandi regis Aragoniae Libri tres introduce la historia que da nombre a la Peña de los Enamorados en Antequera. Trataremos una comparativa con elementos comunes y diferencias como formantes de un canon de Poética histórica.
Los reflejos del espionaje internacional en los espías de Pérez-Reverte
Authors: Ramón García Emilio
Published: March 2022

Arturo Pérez-Reverte siempre ha mostrado gusto por los escritores clásicos para seguir su modelo de historias bien contadas por medio de una narración rápida y precisa y diversidad de referencias intertextuales. Durante décadas, ha explorado la novela histórica, el género de aventuras con un toque de misterio y el género bélico, en donde muestra una visión de la guerra bastante sucia y nada romántica. Si bien se ha escrito mucho acerca de sus héroes cansados y del carácter existencialista y bélico de los mismos, aún no está muy explorada la vena del género del espionaje que recorre algunas de sus obras hasta legar a la trilogía de Falcó y las similitudes que presenta respecto a algunas de las obras más significativas del género. El objetivo del presente trabajo es analizar cómo se integran los rasgos de la ficción de espías de Pérez-Reverte en el género de la novela de espías a nivel internacional y presentar algunas de las características y tópicos que comparte con algunos de los principales nombres del género como Robert Ludlum, Len Deighton, Somerset Maugham, Eric Ambler y John Le Carré en el marco de los parámetros que proponen Boltanski, Corcuff, Mandel, Tadié, Magris y Wolfe para definir el subgénero de la novela de espías.

Racism and Racial Discrimination in the United States
Authors: VOICU Gabriel
Published: March 2022

During the days of American slavery, many whites held stereotypes of African-Americans
as inferior, unevolved, incapable. In societies such as the United States, which are
characterized by unequal cultural power, prejudiced ideologies, usually affected by history,
there is a solid reason for which dominant groups (e.g. whites) sustain and legitimate their
power over other groups (e.g. African-Americans, Hispanics, Asians). The present paper is
designed to see whether stereotypes during Jim Crow have persisted after the civil rights
movement, event that was meant to bring equality and push the United States into a postracial era. Moreover, this analysis aims to extend the current research on the portrayal of
ethnic minorities in advertising, especially in the case of African-Americans. After
establishing an analytical and theoretical framework based on the relationship between
racial ideology and stereotypes of African-Americans, this study investigates how AfricanAmericans are represented in American advertising and how racial ideology is embedded
within those depictions.
Podmiot ucieleśniony w zaprojektowanym środowisku. Analiza wykorzystania koncepcji afordancji w architekturze
Authors: Tofilski Mateusz , Stawski Filip
Published: March 2022

The subject embodied in the designed environment. Analysis of the use of the affordance concept in architecture: James Gibson’s ecological psychology is considered as one of the research subtraditions within embodied cognition. Gibson emphasizes the nature of the agent-environment interaction through the development of the theory of affordances. According to this idea, affordances are relational properties of the environment that enable a specific action for the agent. Currently this concept is being applied in many different contexts. This paper considers the application potential of affordance in architectural studies as a tool that analyses the agent’s interaction with the environment. In this context, the affordance category can be a tool that allows one to take into account the importance of space for the shaping of behavior and interactions between its users, without falling into architectural determinism. The main aim of this study is to analyze affordances as a category that, despite its diversity and vagueness, can play an important role in the embodied view of architecture (which integrates phenomenological trends in architecture and the results of neurocognitive research). The first part of the article is an attempt to synthetically place affordances in the context of embodied cognition and to point out the basic philosophical interpretations and discussions related to Gibson’s concept. In the next part, we situate the concept of affordances in the context of design practice. We also present the pros and cons of applying affordances to this ground. The last section in presenting the concept of affordances is considered within the background of the embodied current in architecture.

Object and purpose of research. This paper discusses ice loads on shaft-lines of icebreakers and ice-going ships as their propellers interact with ice. These loads are needed as inputs for development and fine-tuning of electric propulsion control systems, including those involving load test rigs, with the final purpose of ensuring reliable and safe operation of electric propulsion plants in ice navigation conditions. Materials and methods. This study is based on the publications about ice loads on shafting of electric propulsion plants. It analyses the terminology used in the papers on this subject. It also analyses the data on ice-induced shafting torques, as obtained from full-scale trials of Akademik Tryoshnikov ice-class research vessel. Main results. The paper describes typical cases of extreme ice loads on the propulsion system, with the input data characterizing these loads and needed, in particular, for numerical simulation of ice loads on shafting in order to fine-tune electric propulsion control system by means of computer-based simulations or laboratory tests. The paper shows the importance of considering the inertial elements of the shaft line for correct determination of limit loads. It also formulates the challenges that have to be solved in order to obtain efficient control systems for electric propulsion plants of icebreakers and ice-going ships. It determines the requirements to special full-scale trials needed to validate calculation methods for shafting loads. Conclusion. Electric propulsion systems of ice-going ships must have highly efficient control tools for the propulsion motor that would ensure its reliable and safe operation as propeller interacts with ice. Such a tool is quite hard to obtain because shafting loads are quite various and difficult to predict. One of the ways to improve an electric propulsion system is to build up a test rig with the load part simulating various scenarios of shafting loads as per the mathematical model specially developed for this purpose and validated by the accumulated database of full-scale ice loads on shaft lines. The paper also demonstrates that propulsion motor control system must properly take into account not only external loads but also inertial torques of shaft line, motor rotor and propeller with added water mass.

Object and purpose of research. This paper discusses a three-layered plate made up by two rigid anisotropic layers and soft isotropic medium layer of viscoelastic polymer. Each of the two rigid layers is an anisotropic structure formed by a finite number of arbitrarily oriented orthotropic viscoelastic composite layers. The purpose of this work is to develop a numerical solution method for decaying vibration equations of three-layered unsupported rectangular plates. Materials and methods. The system of algebraic equations is constructed as per Ritz method using Legendre polyno-mials as coordinate functions. The first step is to find real solutions. To find complex natural frequencies of the system, their initial values are taken as real natural frequencies thus found, with subsequent calculation of complex frequencies as per the method of third-order iterations. Main results. This paper discusses the results of convergence analysis for a numerical solution of differential motion equations with respect to an unsupported rectangular three-layered plate with transversally isotropic rigid layers. The material for these rigid lay-ers is unidirectional carbon-reinforced plastic (CRP) with elastic dissipation properties, within the investigated range of frequencies and temperatures, independent on its vibration frequency. For the soft isotropic medium layer of viscoelastic polymer, temperature-frequency curve governing the real part of complex elasticity modulus and mechanical loss coefficient is taken into account. Validation of the mathematical model and the numerical solution method, the comparison of calculated and experimental natural frequencies and mechanical loss coefficients for the two variants of three-layered unsupported plate has demonstrated their good correlation. Conclusion. This paper suggests and validates the numerical solution method for decaying vibration equations of three-layered unsupported rectangular plate made up by two rigid monoclinic layers and soft isotropic medium layer of viscoelastic polymer.

Keberadaan timbal didalam lipstik dapat berbahaya bagi kesehatan. Di Pasar Bandar Buat terdapat 5 toko kosmetik lipstik. Lipstik yang dijual diduga mengandung timbal, jika terus digunakan maka akan berisiko terhadap kesehatan. Tujuan penelitian ini untuk menganalisis risiko kesehatan masyarakat akibat pajanan logam timbal pada penggunaan kosmetik lipstik yang diperjualbelikan di Pasar Bandar Buat. Penelitian ini menggunakan metode ARKM (Analisis Risiko Kesehatan Masyarakat). Metode pemeriksaan sampel Spektrofotometri Serapan Atom (SSA/AAS). Jumlah sampel lipstik sebanyak 8 sampel dan 106 responden dengan Purposive Sampling. Hasil penelitian menunjukkan bahwa konsentrasi timbal tertinggi pada lipstik yang sudah mempunyai izin edar pada sampel B sebesar 1,034 mg/kg dan konsentrasi timbal tertinggi pada kosmetik lipstik tidak mempunyai izin edar pada sampel Non BPOM C sebesar 1,255 mg/kg. Berdasarkan hasil uji laboratorium, semua sampel lipstik masih dibawah nilai cemaran logam berat di dalam kosmetik. Tetapi nilai RQ (Risk Quotient) realtime dan lifetime yang didapatkan hampir semua RQ>1 maka dilakukan pengendalian resiko dengan manajemen risiko. Konsentrasi timbal pada lipstik masih dibawah nilai logam berat yang diperbolehkan, tetapi nilai RQ>1 sehingga dapat menimbulkan risiko bagi kesehatan. Maka diharapkan kepada pemakai lipstik agar tidak terlalu sering untuk touch-up (mengoleskan) karena dapat menambah risiko pajanan timbal pada tubuh.

This paper deals with reusing commercially pure aluminum scrap 1100 by converting it toaluminum-based composite reinforced material by using Iraqi silica sand. The sand is preparedand added in weight percentage of 1% and 2%. It is grain size ranges between 50 -75 um.Wettability of the mixture was increased by adding 2gm of pure magnesium. A special electricmixer was used to disperse silica sand grains to support aluminum scrap melt (matrix).Then the composite pieces were cut to samples suitable for tension, compression,hardness, wear, impact, corrosion resistance (in sea water) and microstructure inspection. Thetests have shown that the composite has more resistance to tension, compression, hardness,and wear than the base alloy. This is because sand particles are dispersed uniformly (uniformlydistributed throughout the cast) which hinder the movement of the dislocations slip plane. Onthe other hand, the resistance to impact and corrosion (in sea water for one month) decreasedslightly. In wear resistance test, pin-on-desk was used where load, sliding speed, and slidedistance were kept constant. Microstructure inspection on the base alloy and the compositematerials were made before and after corrosion for comparison between them.

In this study, three laboratory units were constructed and operated in order to investigate the effect of pre-aeration on removal efficiency of ammonia and organic materials for solid waste leachate from Quashi landfill in Duhok city. The effect of aeration times and pH values on the removal efficiencies were also investigated in this study. Each unit consists of a glass reactor with an effective volume of ten liters supplied by the air pumps and plastic tubes that were used to distribute the air-flow evenly throughout the unit. All units were designed to work in parallel at the same operational conditions. The study program was divided into three stages. In the first stage, the aeration times between (6 to 72) hours were used and the pH value for the leachate was on its original level. Whereas in the second and third stages, the same aeration times where used while the pH values of leachate were adjusted to be 10 and 11. The results of the study showed that; the aeration improves the removal of organic matter and ammonia and the removal efficiencies increase with increasing aeration time. In addition, there is no significant difference in the removal efficiencies of ammonia at pH values equal to 10 and 11.

Introduction: Aging and physical disability are often associated with hypertension, obesity and blood sugar levels which are important factors in the development of metabolic syndrome and cardiovascular disease.This study aims to determine the relationship between obesity, hyperglycemia, hypertension and sarcopenia among the elderly at PUSAKA Kalideres, West Jakarta.

Methods: This study used a cross-sectional analytical descriptive study consisting of 107 respondents aged ≥ 60 years at PUSAKA Kalideres, West Jakarta from September 2019 to November 2019. The dependent variable studied was sarcopenia, while the independent variables of the study were obesity, hyperglycemia and hypertension. The criteria for sarcopenia are based on the 2019 Asian Working Group for Sarcopenia (AWGS). Obesity is categorized if the BMI is ≥ 25 kg, hyperglycemia if the fasting blood sugar level is ≥100 mg / dL, hypertension if the blood pressure is ≥140 / 90 mmHg.

Results: Based on 107 respondents, most of them were aged  65 years (62.6%) and most of them were female (70.1%). The results showed 30 respondents (28%) sarcopenia, 51 respondents (47.7%) obesity, 24 respondents (22.4%) hyperglycemia, and 31 respondents (29%) hypertension. Based on bivariate analysis, it shows that age and obesity have a significant relationship with sarcopenia  p = 0.006 (p> ) and obesity p = 0.022 (p> ). The results of multivariate analysis showed that age and non-obesity were associated with sarcopenia (p = 0.005; OR = 4.734; CI = 1.587 - 14.122 and obesp = 0.015; OR = 0.309; CI = 0.120 - 0.796).

Conclusion: Age is a risk factor for sarcopenia in the elderly and those who are not obese have a greater risk of developing sarcopenia.
