Fabrication of Baking-free Bricks from Iron Ore Tailings
Authors: Chen Hongjun , Wang Zi , Pei Lizhai , Xue Zeyang , Yu Chunhu , Fan Chuangang 
Published: March 2020

Background:
Tailings produced from iron ore smelting processes have increased dramatically
in recent decades. The storage of tailings not only needs high cost, but also causes a great
environmental and safety hazard. Therefore, it is urgent to use new technologies to comprehensively
utilize tailings.

Methods:
The phases and micro-morphology of the baking-free bricks were investigated by X-ray
Diffraction (XRD) and Scanning Electron Microscopy (SEM). The optimal components and preparation
parameters of the baking-free bricks were determined by controlling the ratio of the raw materials
and forming pressure. The compressive strength and density of the baking-free bricks were
analyzed by controlling the forming pressure and curing time.

Result:
The optimal components of the baking-free bricks are 65wt.% tailings, 5wt.% titanium
gypsum, 17wt.% slag, 5wt.% acetylene sludge, 8wt.% waste brick powder. The optimal forming
pressure is 10MPa. 28 d compressive strength and density of the baking-free bricks reach 19.8 MPa
and 1622.92 kg.m-3, respectively. Irregular particles and ettringite (Aft) nanorods in the baking-free
bricks contribute to the improvement of the compressive strength and compactness of the tailing
bricks.

Conclusion:
Baking-free bricks were successfully prepared from iron ore tailings by pressure forming
method and exhibited great application promising in the construction field.
A Method to Learn Embedding of a Probabilistic Medical Knowledge Graph: Algorithm Development
Authors: Li Linfeng , Wang Peng , Wang Yao , Wang Shenghui , Yan Jun , Jiang Jinpeng , Tang Buzhou , Wang Chengliang , Liu Yuting 
Published: March 2020

Background
Knowledge graph embedding is an effective semantic representation method for entities and relations in knowledge graphs. Several translation-based algorithms, including TransE, TransH, TransR, TransD, and TranSparse, have been proposed to learn effective embedding vectors from typical knowledge graphs in which the relations between head and tail entities are deterministic. However, in medical knowledge graphs, the relations between head and tail entities are inherently probabilistic. This difference introduces a challenge in embedding medical knowledge graphs.

Objective
We aimed to address the challenge of how to learn the probability values of triplets into representation vectors by making enhancements to existing TransX (where X is E, H, R, D, or Sparse) algorithms, including the following: (1) constructing a mapping function between the score value and the probability, and (2) introducing probability-based loss of triplets into the original margin-based loss function.

Methods
We performed the proposed PrTransX algorithm on a medical knowledge graph that we built from large-scale real-world electronic medical records data. We evaluated the embeddings using link prediction task.

Results
Compared with the corresponding TransX algorithms, the proposed PrTransX performed better than the TransX model in all evaluation indicators, achieving a higher proportion of corrected entities ranked in the top 10 and normalized discounted cumulative gain of the top 10 predicted tail entities, and lower mean rank.

Conclusions
The proposed PrTransX successfully incorporated the uncertainty of the knowledge triplets into the embedding vectors.
Hegemony Unbound: Tradition Gone Awry as the Female Body Mimics a Site of Colonization and Decolonization in Alice Walker’s “Possessing the Secret of Joy”
Authors: Doku Dr. Samuel Obed 
Published: March 2020

Alice Walker’s novel, Possessing the Secret of Joy shares some similarities with many texts written by black Americans, but it is uniquely different because its settings include an African village where the story begins. The novel is rich in intertextuality as it engages other great American authors like W.E.B. Du Bois, Zora Neale Hurston, William Faulkner, feminist bell hooks; and Austrian psychoanalytical theorist, Carl Jung. Beside its psychoanalytical framework and story-telling pattern with multiple narrators, Possessing the Secret of Joy is also grounded in Louis Althusser’s Ideological State Apparatuses (ISAs) and Repressive State Apparatuses (RSAs) theories, as well as in Antonio Gramsci’s hegemony theory.1 These theories exemplify themselves in the way the protagonist in the novel is convinced to succumb to genital mutilation and how a journey into herself to remember long-repressed memories, eventually results in her ability to liberate women of her village. Possessing the Secret of Joy is a modernist novel in which hegemony, patriarchy, and feminism converge to expose an obnoxious practice in an African village in expectations of dismantling the antiquated tradition that informs the novel.
PROFESSOR VALENTINA PAVLOVNA KLESHCHEVNIKOVA (to the 100 th anniversary of the birth)
Authors: Kokhanenko N. Yu. , Shiryaev Yu. N. , Dudanov I. P. 
Published: March 2020

Surgery, as well as almost all sections of medicine, has always been a man’s affair. Valentina Pavlovna Kleshchevnikova (1919–2009), one of the few women who became a professor of surgery, stood out in the mid-20th century galaxy of surgeons. October 2019 marks the 100th anniversary of her birth. Having started her professional career during the Great Patriotic War in a military hospital, she gained experience and knowledge in many areas of surgery. Professor Sergey Vladimirovich Heinatz, her mentor and teacher, had extensive experience in esophageal surgery and while still working in Khabarovsk made – one of the first in the country – esophagoplasty resection with one-stage esophagoplasty. Professor V. P. Kleshchevnikova, a promising surgeon, was also involved in the development of this very difficult field of surgery. It was the material that formed the basis for the candidate’s and later doctoral dissertation of a young, but already experienced specialist. After defending her thesis, V. P. Kleshchevnikova, a young doctor of medical sciences, was elected by competition to head the Department of Hospital Surgery at Petrozavodsk State University (Petrozavodsk). For a long time almost all the leading surgeons of Petrozavodsk and the Republic of Karelia were her students or students of the Department headed by V. P. Kleshchevnikova – someone listened to her lectures, someone worked with her in the clinic or had the honor to «get» Valentina Pavlovna as a mentor or opponent for the defense of the thesis. In Saint Petersburg, at the Mariinsky Hospital, and later at Petrozavodsk State University, a prominent and very bright part of Professor Kleshchevnikova’s surgical and scientific career took place. She was a worthy representative of the pleiad of the most brilliant surgeons, and if we take female surgeons, she was probably the most outstanding surgeon.

Objetivo: Avaliar a presença de disfagia e seu impacto na qualidade de vida de pacientes portadores de doença de Parkinson (DP), correlacionando o estadiamento da doença, a severidade da disfagia e a auto avaliação do risco de disfagia. Métodos: Estudo observacional e transversal, avaliando 24 pacientes portadores de DP através da escala para sintomas motores de Hoenh e Yahr, da avaliação endoscópica da deglutição (VED), de questionário sobre a qualidade de vida (The 39 item Parkinson´s Disease Question - PDQ-39) e de um instrumento de auto avaliação do risco de disfagia e aspiração (Eating Assessment Tool - EAT-10). Resultados: Na VED, 87,5% dos pacientes apresentaram disfagia, com gravidade independente da severidade motora da doença. Não houve significância entre a gravidade da disfagia e a auto avaliação de disfagia e aspiração. No PDQ-39 houve pior percepção sobre a qualidade de vida com o avançar da doença (p=0,003), com significância no domínio da cognição nos disfágicos graves. Conclusão: a disfagia é um sintoma comum e independente da severidade motora da DP, devendo ser investigada e reabilitada por equipe multiprofissional precocemente a fim de reduzir o impacto na qualidade de vida destes pacientes.

Authors: Bung Navneet , Krishnan Sowmya Ramaswamy , Bulusu Gopalakrishnan , Roy Arijit 
Published: March 2020

The novel SARS-CoV-2 is the source of a global pandemic COVID-19, which has severely affected the health and economy of several countries. Multiple studies are in progress, employing diverse approaches to design novel therapeutics against the potential target proteins in SARS-CoV-2. One of the well-studied protein targets for coronaviruses is the chymotrypsin-like (3CL) protease, responsible for post-translational modifications of viralpolyproteins essential for its survival and replication in the host. There are ongoing attempts to repurpose the existing viral protease inhibitors against 3CL protease of SARS-CoV-2. Recent studies have proven the efficiency of artificial intelligence techniques in learning the known chemical space and generating novel small molecules. In this study,we employed deep neural network-based generative and predictive models for de novo design of new small molecules capable of inhibiting the 3CL protease. The generatedsmall molecules were filtered and screened against the binding site of the 3CL protease structure of SARS-CoV-2. Based on the screening results and further analysis, we haveidentified 31 potential compounds as ideal candidates for further synthesis and testing against SARS-CoV-2.

Enjoy the Silence: Pseudolaw at the Supreme Court of Canada
Authors: Netolitzky Donald J. , Warman Richard 
Published: March 2020

Pseudolaw is a collection of legal-sounding but false rules that purport to be law, employed by groups including the Detaxer and Freemen-on-the-Land movements. While pseudolaw is universally rejected by Canadian courts, no Supreme Court of Canada decision addresses these concepts. This study reviews 51 unsuccessful Supreme Court leave applications that potentially involve pseudolaw to determine what pseudolaw issues were raised, whether those issues were comprehensible, and therefore if by its silence the Supreme Court has implicitly rejected these concepts.
Some pseudolaw-related leave applications were not comprehensible to a legally trained reader; however, the remainder clearly imply that the Supreme Court of Canada has been exposed to the cornerstone concepts of modern pseudolaw, including “Strawman” Theory, and has rejected these ideas as not having national significance.

Aortic Stiffness in HIV Infection with and without Antiretroviral Therapy. A Meta-analysis of Observational Studies
Authors: Mulè Giovanni , Mulè Giuseppe , Tranchida Valeria , Colletti Pietro , Mazzola Giovanni , Trizzino Marcello , Colomba Claudia , Cascio Antonio 
Published: March 2020

Abstract
Background
The risk of Cardiovascular (CV) events is higher in HIV-infected patients (HIV+) compared to HIV-uninfected persons (HIV−). Large artery stiffness, a well-documented predictor of adverse CV prognosis, may mediate this enhanced risk. It is usually assessed by measuring aortic Pulse Wave Velocity (aPWV). Studies examining arterial stiffness in HIV+ yielded inconsistent results. We performed a meta-analysis with the aim to evaluate the association of HIV infection and its therapy [Antiretroviral Therapy (ART)] with aPWV.

Design and Method
The Standardized Mean Difference (SMD) and corresponding 95% confidence intervals were calculated for aPWV in different comparison groups. Statistical heterogeneity, assessed by Q-test and I2` statistic, was observed in all these comparisons. Therefore, random effects model was implemented.

Results
In a total of 12 studies, naive HIV+ (n = 547) showed increased aPWV compared to HIV− (n = 864): SMD = 0.333 (0.125–0.542), p < 0.002. A total of 22 studies were identified comparing HIV+ treated with ART (n = 3348) to HIV− (n = 2547) showing higher values of aPWV in the former than in latter: SMD = 0.391 (0.225–0.556), p < 0.001. In 10 studies, HIV+ treated with ART (n = 761) exhibited greater aPWV values than those of naive HIV+ (n = 457): SMD = 0.262 (0.006–0.518), p = 0.045.

Conclusion
Our meta-analysis seems to suggest that HIV infection “per se” and ART may impair aortic distensibility. However, interpretation of our results needs caution due to between-study heterogeneity and some potential publication biases.
Rancang Bangun Pengendali Dan Pengawasan Gas Amonia Pada Peternakan Ayam Berbasis Arduino Mega 2560 R3
Authors: Raharjo Adi Sapto , Jamal Zaidir 
Published: March 2020

Kadar gas amonia menjadi salah satu permasalahan yang kerap terjadi pada peternakan ayam. Ambang batas maksimal untuk kadar gas amonia yaitu 20 PPM (Part Per Million). Gas amonia muncul karena suhu yang tidak ideal pada kandang ayam. Diketahui bahwa suhu yang optimal pada kandang ayam dengan suhu 300C (Celcius). Kenaikan kadar gas amonia yang tidak terekam juga merupakan permasalahan karena pemilik atau pengelola ayam tidak bisa mengontrol dan mengetahui apabila terjadi kenaikan kadar gas amonia. Dari permasalahan tersebut dirancangnya sistem pengendali kadar gas amonia dengan sensor MQ-135 sebagai sensor yang akan mendeteksi kadar gas amonia dan sensor DHT11 yang akan menjadi sensor yang mendeteksi suhu ruangan kandang ayam. Hasil pembacaan sensor gas dan sensor suhu diproses oleh arduino sebagai mikrokontroler. Sistem ini juga akan menyimpan kadar gas amonia yang terdeteksi oleh sensor MQ-135 kedalam database pada aplikasi monitoring tiap menit agar apabila terjadi kenaikan kadar gas amonia dapat terdeteksi kapan kenaikan kadar gas amonia terjadi. Keluaran dari sistem ini akan ditampilkan kadar gas amonia dan suhu ke layar LCD 16x4 serta mikrokontroler yang mengirimkan signal ke driver relay untuk menghidupkan blower apabila kadar amonia yang terdeteksi melebihi 20 PPM lalu mengeluarkan gas amonia ke luar kandang ayam dan menghidupkan heater apabila suhu yang terdeteksi kurang dari 30oC untuk mengendalikan suhu kandang ayam.
Hyväksymis- ja omistautumisterapian työkalujen hyödyntäminen terveyssosiaalityössä
Authors: Kauravaara Kati 
Published: March 2020

Sosiaalityöntekijöitä on kannustettu hyväksymis- ja omistautumisterapian työkalujen hyödyntämiseen, ja työkaluja onkin käytetty sosiaalityön kontekstissa ulkomailla. Suomessa sosiaalityöntekijät ovat tutustuneet aiheeseen niukasti. Työkalut tarjoavat keinoja työskennellä mielen kanssa, purkaa kielellisesti syntyneitä asioiden, ajatusten, tunteiden, tuntemusten ja kokemusten välisiä suhteita ja siten heikentää kielellisyyden vaikutusta asiakkaan kannalta ongelmallisilla elämänalueilla sekä vahvistaa oppimista oman kokemuksen kautta. Keskeistä on lisätä psykologista joustavuutta kuuden ydinprosessin avulla: hyväksyntä, mielen kontrollin heikentäminen, tietoinen läsnäolo nykyhetkessä, havainnoiva minä, arvojen kirkastaminen sekä sitoutuminen omien arvojen mukaiseen toimintaan.
Hyväksymis- ja omistautumisterapian konkreettiset työkalut soveltuvat sosiaalityöntekijän käytettäväksi, vaikka niiden hyödyntäminen edellyttää erityistä perehtymistä. Erityisesti hyväksymis- ja omistautumisterapian työkaluilla on annettavaa sosiaalityöntekijän keinoina psykososiaalisen tuen antamisessa.

Welcome to the final issue of the first volume of LUMAT. With two regular issues, three special issues, eleven research articles, two perspective articles and thirty general articles published, the first volume of LUMAT has been a success. With three special issues and two regular issues lined up for the second volume, we hope to continue publishing quality articles on research and practice in math, science and technology education.
The purpose of the journal is to share good practices, and present especially Finnish but also international know-how in the field of math, science and technology education. With this purpose in mind, it has been a pleasure to publish several manuscripts from our colleagues around the globe. Also this final issue of the first volume includes articles from Finnish as well as international educational researchers.
The first article, by Jeronen, Karjalainen, Kuoppala, Sääskilahti and Tirri discusses the new student admission process of subject teacher education. Their topic is especially interesting, as the coming years are about to bring changes to student admission processes of Finnish universities.
The second article is a product of an international collaboration with Finnish and North American researchers. The study by Tolppanen, Rantaniitty, McDermott, Aksela and Hand investigates how Finnish comprehensive school students received a multimodal writing lesson. They conclude that general writing skills benefit students in production of multimodal writing during science lessons.
The last study published in this issue discusses the use of classroom response systems (also known as clickers) in physics teacher education. According to the results of the North American researchers Milner-Bolotin, Fisher and MacDonald clicker-enhanced pedagogy is a promising vehicle for developing pedagogical content knowledge of science teachers. The results of this study are interesting also from a Finnish perspective, as also Finnish teacher educators are searching new ways to implement use of modern educational technology to science and mathematics teacher education.

Published: March 2020

Many varieties of bean are widely grown across diverse agro-ecological zones in Nepal. And opportunities exist for improving the crops and enhancing their resilience to various biotic and abiotic stressors. In this context, an experiment was conducted from June to October 2016 in Khar VDC of Darchula district to study the phenotypic traits of nine landraces of bean (Phaseolus vulgaris L.). The bean landraces were planted using randomized complete block design in three sites (Dhamidera, Dallekh and Sundamunda villages), with three replications in each site for their comparative analysis. The study considered the following phenotypic traits: days to emergence, days to 50% flowering, days to 90% pod maturity, number of nodes, pod length, pod width, number of pods, number of seeds per pod and weight and grain yield for 100 seeds. Kruskal-Wallis test showed significant differences in the landraces both within and among locations. KA-17-08-FB and KA-17-04-FB were late flowering (63 and 65 days respectively) compared to other landraces whereas KA-17-07-FB flowered earliest (within 42 days). In all three sites, three landraces namely KA-17-07-FB, KA-17-04-FB and KA-17-06-FB were found to be relatively more resistant to pest and diseases than other landraces. Eight out of nine landraces in Dhamidera and Dallekh villages and seven out of nine in Sundamunda village produced seeds greater than 1.0 t/ha. Among the nine varieties KA-17-02-FB was the highest yielding variety, with an average yield of 3.8 t/ha. This study is useful for identifying suitable landraces for future promotion based on their maturity, grain yield, diseases resistance and other qualitative and quantitative characteristics.

Published: March 2020

Los efectos adversos de los opioides son el resultado de interacciones con sus receptores a nivel cerebral. Cuando se administran por vía intratecal se ha descrito depresión respiratoria, aunque con menor frecuencia que en uso endovenoso. Objetivo: describir la ocurrencia de efectos adversos en pacientes llevados a cirugía en el Hospital de San José de Bogotá D.C. que recibieron fentanyl intratecal como adición a bupivacaína hiperbárica. Materiales y métodos: estudio descriptivo de una cohorte de pacientes llevados a cirugía en el Hospital de San José entre 1º de octubre de 2007 y 30 de septiembre de 2009, que recibieron anestesia subaracnoidea aplicando fentanyl intratecal y bupivacaína hiperbárica. Se incluyeron los pacientes de 18 a 65 años, las no gestantes y aquellos sin conversión a anestesia general. Resultados: se estudiaron 313 pacientes, 39,9% mujeres con edad promedio de 42 años (DE:12,7), clasificación ASA distribuida en ASA I, a0,7%; ASA II, 33,3%; ASA III, F,7% y ASA IV, 0,3%. Los efectos adversos más comunes fueron náuseas 8,6% (n:27), prurito a,7%(n:21), vómito 2,2% (n:7) y bradicardia 2,2% (n:7). La depresión respiratoria se presentó en 1,3% (n:4). Conclusiones: la frecuencia de depresión respiratoria que reportamos se encuentra en el rango de la literatura; sin embargo, hay que considerar que no existe consenso en la manera como se mide. Los demás eventos adversos fueron menos que los reportados.
