Authors: Rivasplata Heather , Dettmann Nicole , LeVan Emily R. , Santos Gutierrez Callisaya Erasmo , Sarmiento Callejas Rita , Blood-Siegfried Jane , Felsman Irene C.
Published: February 2021

Bolivia's recent enactment of universal health care to increase access and delivery of health services can increase health care demands in underresourced, rural communities. We describe how a global intradisciplinary partnership assessed changing health care needs in a recently expanded hospital in the Bolivian Amazon Basin. The collaboration resulted in designing and implementing an evidence-based triage training program to improve rapid assessment and health outcomes. The interdisciplinary triage training of 19 nurses and physicians showed a significant improvement in their knowledge and implementation capacity, as demonstrated by pre- and posttest scores. As an intradisciplinary team, trainees significantly increased consistency in triage assignments in nine of 10 clinical triage posttraining vignettes. We share insights to overcome unseen challenges and improve future data-driven, evidence-based global implementation projects.

Radical Excision and Reconstruction of Chronic Tibial Osteomyelitis With Microvascular Muscle Flaps
Authors: Kuokkanen Hannu O M , Tukiainen Erkki J , Asko-Seljavaara Sirpa
Published: February 2021

Abstract

We report a series of 21 patients with chronic osteomyelitis of the tibia treated with microvascular muscle flap reconstruction. All patients underwent a radical bone and soft-tissue excision until healthy, well-bleeding tissue was exposed. Six patients required cancellous bone grafting. Latissimus dorsi was used in 14 patients, gracilis in A1 and rectus abdominis in 4. One gracilis flap was lost due to vessel thrombosis and was replaced with a rectus abdominis free flap.

Average follow-up was 2.5 years. There was no evidence of clinical infection in 20 patients at follow-up; the bone had healed, the soft-tissue cover was stable, and the laboratory parameters were normal. Bone infection recurred in 1 patient, resulting in a below-knee amputation.

The radical excision of infected bone and affected soft tissue and reconstruction with a well-vascularized large freemuscle flap is an excellent solution in most difficult chronically infected cases.

Authors: Shang Rongyan , Peng Changqing , Shao Pengfei , Fang Ruiming
Published: February 2021

This study aimed to propose an equal-integral-bandwidth feature extraction method based on fast Fourier transform (FFT) to solve the problem of cumbersome processing and a large amount of calculation in the common feature extraction algorithm for vibration signals of on-load tap changer (OLTC). First, the vibration signals of OLTC were preprocessed in segments, which highlighted the status features and avoided the shortcomings of the FFT spectrum that lacked time axis information. Second, the vibration signal segments were analyzed with FFT, and the generated signal spectrum was divided into several segments according to equal integral. The bandwidth coefficient obtained in each segment was the characteristic value. Third, this study proposed that adding appropriate time domain features and further improving the algorithm could improve the accuracy of fault diagnosis. Finally, the main mechanical faults of OLTC were simulated, and the vibration signals were collected to carry out the fault diagnosis experiment of OLTC. The results showed that the FFT-based equal-integral-bandwidth feature extraction method was simple in processing, small in calculation, easy to implement in an embedded system, and had a high accuracy of fault diagnosis.

Published: February 2021

Nanotechnology has vast applications in virtually all the fields including health and environment. Nanomaterials have different origins like plants, animals, metals, and microorganisms. They have larvicidal activities against mosquito larvae that cause malaria and dengue fever which are most malicious parasitic diseases of human beings. Multidrug resistance of malaria has been reported in different parts of Southeast Asia especially to the first line of antimalarial drugs. Nanomaterials having different origin, sizes, concentrations, and shapes, have varied efficacy against the vectors which are comparable with the commercially available insecticides and even have better results than the same. Nanomaterials can be used as an alternative to commercially available insecticides for the eradication of vectors causing both the diseases. In this chapter, types, sources, composition, larvicidal potential against vectors of nanomaterials have been discussed along with possible toxicity and future recommendations on the eco-friendly approach for the control of mosquito-borne diseases.

Published: February 2021

Immunotherapy has become a preferable candidate for many diseases in recent days. The infusion or administration of immune complexes or components to elicit the own immune response against a particular disease by attracting the antigen presenting cells against the disease causing organism and eliciting the T-cell mediated killing and further activating cell mediated immunity based on the processed surface antigens underlies the basic concept behind the immunotherapy. Immunotherapy can be applied for all course of diseases even in the treatment of cancer. The limitation in using immunotherapy is that it needs a proper delivery vehicle to reach the diseased spot to shows its pharmacokinetic property. In case of cancer, the immune components administered itself are not able to pertain and penetrate the solid tumor mass. Nanoparticles are small-sized particles which are generally specific in action used in the field of medicine. Nanoparticles aid in targeted drug delivery to the specific spots and immune targeting of nanoparticles is due to its enhanced permeability and retention (EPR).

A Communication Model Based on Fractal Geometry for Internet of Things
Authors: Salinas Sergio Ariel
Published: February 2021

Internet of things (IoT) is a paradigm that involves an increasing number of human activities. IoT fuses heterogeneous electronic devices and processes into cyber physical system (CPS) to improve conventional processes efficiency in terms of performance and resource usage. The Institute of Electrical and Electronics Engineering (IEEE) has polled more than 150 IoT scenarios based on CPSs to be developed in the next years. A CPS is strongly coupled to a communication system for interchanging data among devices that orchestrate actions in certain environments such as a factory. In general, a decentralized communication model is more resilient and efficient in data traffic management than centralized model. A problem with decentralized models is how to keep track of nodes location without a centralized service that keeps updated data of nodes. This work describes a decentralized model where any node is able to be located based on its identification in the system.

Authors: Salinas Sergio Ariel
Published: February 2021

The internet has changed the way human activities are performed. In a few years, this communication infrastructure evolved to leverage a new technological paradigm named internet of things (IoT). This technology fuses processes and devices to create multipurpose cyber-physical systems (CFS) that improve human quality of life. These systems rely on internet availability, which can be affected by natural phenomena such as earthquakes carrying out economic and social consequences. In this work, an autonomous communication model for IoT domains is proposed. The main goal of this model is to set the basis for the development of a communication system capable of operating independently of the internet. This communication autonomy is critical in catastrophe scenarios where information broadcasts can support disaster management. According to simulation results, the proposed model can be implemented in different IoT scenarios including cities developed under this technology.

Numerical Investigation of the Effects of Bucket Handle Tears and Subtotal Medial Meniscectomies on the Biomechanical Response of Human Knee Joints
Authors: Devaraj Ashwin Kumar , Acharya Kiran Kumar V , Adhikari Raviraja
Published: February 2021

Understanding the complex biomechanical behaviour of the injured and meniscectomised knee joints is of utmost significance in various clinical circumstances. The objective of this study is to investigate the effects of bucket handle tears in the medial meniscus and subtotal medial meniscectomies on the biomechanical response of the knee joints belonging to multiple subjects. The three-dimensional (3D) finite element models of human knee joints including bones, cartilages, menisci, ligaments and tendons are developed from magnetic resonance images (MRI) of multiple healthy subjects. The knee joints are subjected to an axial compressive force, which corresponds to the force of the gait cycle for the full extension position of the knee joint. Three different conditions are compared: intact knee joints, knee joints with bucket handle tears in the medial meniscus and knee joints after subtotal meniscectomies. The bucket handle tear causes a considerable rise in the maximum principal stress at its tip compared to that at the same location in the intact meniscus. This would cause the total rupture of the meniscus resulting in cartilage damage. Subtotal meniscectomy causes a considerable reduction in the contact area along with a substantial increase in the contact pressure and maximum compressive stress in the cartilages in comparison with that in the intact knee. This could give rise to severe degenerative changes in the cartilage. The results of this study could help surgeons in making clinical decisions when managing patients with meniscal injuries.

The aim of this paper is to develop an efficient breast cancer Computer Aided Diagnosis (CAD) system allowing the analysis of different breast tissues in mammograms and performing textural classification (normal, mass or microcalcification). Although several feature extraction algorithms for breast tissues analysis have been used, the findings concerning tissue characterization show no consensus in the literature. Specifically, the challenge may be great for mass and microcalcification detection on dense breasts. The proposed system is based on the development of a new feature extraction approach, the latter is called Multi-threshold Modified Local Ternary Pattern (MtMLTP), it allows the discrimination between various tissues in mammographic images allowing significant improvements in breast cancer diagnosis. In this paper, we have used 1000 ROIs obtained from Digital Database for Screening Mammography (DDSM) database and 100 ROIs from a local Tunisian database named Tunisian Digital Database for Screening Mammography (TDDSM). The Artificial Neural Network (ANN) shows good performance in the classification of abnormalities since the Area Under the Curve (AUC) of the proposed system has been found to be 0.97 for the DDSM database and 0.99 for the TDDSM Database.

The principal aim of this research is using biosynthesized ZnO-CaO nanoparticles (NPs) for preparation of indole derivatives. ZnO-CaO NPs have been prepared using Zn(CH3COO)2 and eggshell waste powder in solvent-free conditions. Morphology and structure of NPs were determined by FT-IR, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy dispersive spectra (EDS). It was used as a highly efficient catalyst for the synthesis of indole derivatives. Some indole derivatives were synthesized by the reaction of indole, formaldehyde, aromatic and aliphatic amines in the presence of ZnO-CaO NPs (5 mol%) in ethanol under reflux conditions. The assigned structure was further established by CHN analyses, NMR, and FT-IR spectra. Because of excellent capacity, the exceedingly simple workup and good yield, eco-friendly catalyst ZnO-CaO NPs were proved to be a good catalyst for this reaction.

The available of conventional fuels are fluctuating depend on distribution from the source production to consumer. The availability of biogas as renewable energy is increasing due to establishments of many organic wastes processing worldwide. The need of electricity to support daily life activity is a must, but the availability of electric source in remote area is limited especially for a farm that far away from commercial line distribution of electricity. This work is dedicated to solve this problem. The single cylinder 4 stroke spark ignition engine (83 cc) was designed to be able to be fuelled flexibly by using biogas or liquefied petroleum gas (LPG), or gasoline if sometime the biogas not available during initiation of the process or during maintenance of anaerobic digester. The engine is still can be run to provide electricity by using conventional fuel such as LPG or gasoline. The full consumption as well as emission of this flexible fuel engine was investigated. It is found that the fuel consumption is 9.97 L/mint for Biogas, 0.004 L/mint for gasoline and 2.24 L/mint for LPG. Surprisingly by using biogas the emission of carbon monoxide (CO) was down to almost zero (0.02 ppm), comparing gasoline 0.32 ppm, and LPG 0.4 ppm.

Biogas quality in many installation of anaerobic digester for processing organic waste are found not optimum, especially in developing country where understanding of anaerobic processing is not well known. The methane content in the biogas are usually low that make it not possible to be utilized as a fuel of the engine. Biogas Purification usually will be introduced as a solution. But this idea is about complicated for simple or small anaerobic digester. Other solution is suggested by using enrichment of biogas by using other fuel such as hydrogen or blended with city gas such as LPG gas. But for preparing hydrogen gas or commercial will also costly. This research introduces simple technique for biogas enrichment by using denatured alcohol. The biogas contents were found around 30% vol. methane (CH4) and around 2% Carbon dioxide (CO2). The price of denatured alcohol is relative cheap because the selling tax is not as much as drinking alcohol. Engine with bigger combustion (420 cc) chamber was prepared for this purpose to make possible to be fueled with biogas. The compression was set to reach 10 bar. The clearance of the both intake and exhaust valve was set in order to be possible to be running by using biogas. The biogas-air mixer was design for this purpose. The carburetor was set for use of denatured alcohol. It is found that the engine is running well by using biogas fuel that is enriched by using denatured alcohol. The emission was found better comparing using gasoline for the same engine. The fuel consumption is reported for future economic analyses.

Authors: Eugenio Francis Darwin T. , Pajarito Bryan B.
Published: February 2021

Iron oxides and similar inorganic compounds have served as anti-corrosion fillers for metal coatings. Environmental issues related to the mining of metallic fillers have stimulated interest in alternative fillers such as organic fillers. This paper explores the use of comminuted waste plastic sachets (WPS) as an anti-corrosion filler to resin-based metal coating. Mixture design of experiment was used to study the effect of iron oxide-WPS blends on the film thickness, viscosity, corrosion behavior, and water resistance of the coating. Results show that the film thickness was affected by the presence of iron oxide while the viscosity of the coating was affected by high loads of WPS. Among all coatings, the blend containing 25% iron oxide and 75% WPS produced the highest corrosion resistance. In conclusion, comminuted WPS provided additional corrosion resistance and could serve as an alternative anti-corrosion filler.
Chemotherapy for osteosarcoma
Authors: Chen Tien-Hua , Hung Giun-Yi , Yen Chueh-Chuan
Published: February 2021

Objective:

This article reviews the current standard of care for osteosarcoma and the experience of Taipei Veterans General Hospital.

Data Sources and Study Selection:

We searched PubMed using the keyword “osteosarcoma” and article type “Clinical Trial.” Prospective, randomized, Phase II/III clinical trials which resulted in practice change were enrolled. In addition, retrospective studies from Taipei Veterans General Hospital were also included.

Results:

For localized conventional osteosarcoma, combined perioperative chemotherapy with surgical resection dramatically improved long-term outcomes. Combination chemotherapy with methotrexate, Adriamycin, and cisplatin (MAP) is currently widely accepted to be the optimal regimen. The efficacy of chemotherapy has increased the likelihood of a limb-salvage approach, which has become the mainstay of surgery. In Taipei Veterans General Hospital, MAP plus ifosfamide was used and could achieve a 5-year overall survival (OS) rate of 77% and progression-free survival (PFS) rate of 70% for all patients. For nonmetastatic osteosarcoma, the 5-year OS and PFS rates reached 90% and 83%, respectively. For recurrent/metastatic disease, there is currently no satisfactory systemic therapy. Removal of all tumors should be attempted if clinically feasible, because one-third of patients may survive for 5 years or more if the tumors are completely resected.

Conclusion:

Perioperative chemotherapy is associated with excellent OS, PFS, and limb salvage rates and is the current standard of care for osteosarcoma.

Published: February 2021

As of January 2021, 1 year has passed since the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first discovered, which is the cause of the coronavirus disease-2019 (COVID-19) pandemic that has infected almost 100 million people worldwide and caused almost two million deaths. In 2020, in an unprecedented scientific achievement, several vaccines were developed, underwent clinical trials, and were distributed worldwide. This was made possible, in part, by Operation Warp Speed, which promoted mass production of multiple vaccines through different technological platforms, relying on preliminary evidence to allow faster distribution as soon as clinical trials confirmed one or more of those vaccines to be safe and effective. The Kingdom of Saudi Arabia (KSA) was one of the very first countries in the world to grant emergency use authorization to the BNT162b2 vaccine, a new type of modified RNA vaccine developed by Pfizer-BioNTech. Here, we review various COVID-19 vaccines and the success of the vaccine rollout in KSA.

This work concerns the field of recycling of waste intobuilding materials. It reports on the possibility ofrecovering plastic waste and related products fromthe wood industry, in construction. The objective ofthe study is to give added value to wood-plasticcomposites produced using the cold compressionmolding process, by improving their mechanicalproperties. Through the bending test, the influence oftwo manufacturing parameters - compactionpressure and drying temperature after molding - onthe mechanical properties, was evaluated for the caseof a composite based on tropical wood sawdustcoming from Benin and recycled polystyrene (CBPo).It appears that the compaction pressure and thedrying temperature are essential factors to considerwhen evaluating the mechanical performance of thecomposite. Increasing the compaction pressure to alimit value significantly improves the properties of thematerial. The optimal properties of CBPo wereobtained at a pressure of 7 MPa. Post-forming dryingat 100 ° C also significantly improved the performanceof the composite. In addition, thanks to its enhancednew mechanical properties, the CBPo is repositionedrelatively to other existing materials, thus making itpossible to think about new applications inconstruction.

Oral Valproate Sodium as an Alternative to Benzodiazepine in the Treatment of Catatonia- A Case Report
Authors: Maier Jacob , Rapport Daniel , McCormick Alex , Lewis Chandani
Published: February 2021

Alternative therapies are necessary to treat catatonia in patients with comorbidities that are not amenable to therapy with benzodiazepines or ECT. This is a patient with schizophrenia with catatonic features and a history of polysubstance abuse. Consequently, he was not a candidate for treatment with benzodiazepines, so an alternative needed to be found. GABAergic medications have been used previously as alternatives to benzodiazepines and ECT. In this case we chose sodium valproate, due to its cross-reaction with GABAergic systems. There are five reported cases using sodium valproate. Three of which were treated with intravenous valproate, while the remaining two do not specify the route of administration. We present a case where oral sodium valproate was used successfully for both acute and long-term catatonic treatment. To our knowledge, no other report has looked at both acute and long-term treatment with sodium valproate. Oral sodium valproate can be considered for patients with substance use disorders like COPD, sleep apnea or myasthenia gravis in which benzodiazepines are contraindicated and where ECT is not an option for treatment.
El pensamiento político islámico y la propaganda terrorista

Published: February 2021

Los movimientos yihadistas actuales son islamismos radicales que buscan imponer el califato global, controlar la vida pública y privada de las personas, y prescindirse de los sistemas democráticos o representativos. El surgimiento de ese pensamiento es bastante complejo y varía entre países, grupos y corrientes religiosas. La escuela jurídica hanbali en opinión de muchos expertos es la que va a sentar las bases de esa corriente política, al proponer la Sharía y el Califato como principales argumentos de un discurso político que buscaba conformar un modelo “perfecto” de sociedad regido de acuerdo con “la ley divina”.
"San Max" releído. Una defensa de Stirner contra Marx
Authors: D´  Angelo Valerio
Published: February 2021

Max Stirner siempre ha sido considerado un pensador menor en la teoría política moderna. Una de las razones de este olvido se debe tal vez al ataque al vitriolo que Marx y Engels le dirigieron en el largo apartado “San Max” en La Ideología Alemana, donde Stirner es descrito como la quintaesencia del filósofo idealista que ignora las relaciones de fuerza y poder que gobiernan la realidad, reduciéndola a una mera representación de la conciencia. “Contra” Marx y Engels, en este escrito se defenderá la tesis según la cual Stirner, lejos de ignorar los factores materiales de la ideología, desvela la técnica oculta de la nueva gobernabilidad liberal: la transformación del individuo en creyente. Se seguirá entonces el análisis stirneriano del sometimiento ante lo sagrado como condición imprescindible para la dominación. De allí se verá cómo, en la época moderna, lo sagrado se ha reconfigurado bajo la forma de nuevos “espectros” que piden obediencia al individuo. Por último, se explorará la propuesta stirneriana de la insurrección como técnica de emancipación de lo sagrado y de la necesidad psicológica del creer.
La República Dominicana y la privación arbitraria del derecho a la nacionalidad de las personas de origen haitiano conforme a la sentencia TC/0168/13
Authors: Senatus Kénel
Published: February 2021

En la República Dominicana, el derecho a la nacionalidad de las personas nacidas en el país y de origen haitiano es tratado con discriminación. Por medio de una reinterpretación amplia de la expresión «extranjeros “en tránsito”», la Sentencia TC/0168/13 del Tribunal Constitucional privó arbitrariamente de su nacionalidad a numerosas personas de origen haitiano, la cual había sido adquirida por el principio del ius soli. El pretexto utilizado para llevar a cabo esta privación de la nacionalidad fue que los padres de las víctimas de dicha decisión no poseían un estatus migratorio legal. Considerada incompatible con las normas del derecho internacional de los derechos humanos, esta decisión hace prevalecer la soberanía estatal sobre el derecho a la nacionalidad, lo cual ha provocado una crisis que difícilmente puede resolverse.

Authors: Pepperell Jennifer , Rubel Deborah
Published: February 2021

This research explored the experiences of gifted girls transitioning from elementary school to sixth and seventh grade. The current literature indicates that gifted girls often struggle emotionally during this transition. Seven research participants were selected and interviewed over a four-month period. Grounded theory methodology was used to analyze data, generate subsequent interview questions, and build theory. This study indicated that these gifted girls transition was facilitated by their strong identities, which enabled them to balance their social and academic lives. Their strong identities allowed them to choose strategies that helped them build connections with both gifted and nongifted peers. These relationships contributed significantly to their sense of self, and in turn supported their transition experiences.
On Being Degraded in Public Space: An Autoethnography
Authors: Schoepflin Todd
Published: February 2021

In the form of an autoethnography, the author analyzes a violent attack he suffered in public and discusses how the incident relates to a degradation ceremony.

Unlike a degradation ceremony, transformation of ones total identity is not a required outcome of a degradation incident. The significance of being degraded in public without experiencing a transformation of total identity is discussed.

Little is known about the experience among adult children who have a parent with Parkinsons Disease (PD). The purpose of this study was to explore, appreciate, and describe their experiences using a phenomenological methodology. Narratives were collected from seven participants who have a parent diagnosed with PD and analyzed according to Colaizzis (1978) phenomenological data analysis method. Seven thematic clusters were identified and an exhaustive description is presented to summarize the essence of their lived experience. The study indicates a strong sense of essential positivism from the participants stories, and overall, it seems PD has brought some degree of biological, psychological, socially, and/or spiritual meaning to their lives that they may not have otherwise noticed or experienced.

ABSTRAK

Covid 19 telah menular kepada hampir semua negara di dunia. Sejauh ini angka kematian yang diakibatkan oleh covid 19 ini di seluruh dunia telah mencapai angka 340.383 orang. Nampaknya angka ini akan terus bertambah, mengingat penyebaran virus ini begitu cepat, menjalar seperti api. Dalam tulisan ini akan dianalisa apakah ada hubungan antara nubuatan dalam Wahyu 6:8 dengan covid 19 ini.

Untuk mencapai tujuan itu, penulis menggunakan pendekatan kualitatif dengan metoda eksegesis terhadap teks Wahyu 6:8. Dari penelitian yang dilakukan bahwa sejauh ini jumlah kematian yang diakibatkan covid 19 masih jauh lebih kecil dibandingkan dengan jumlah kematian yang dinubuatkan dalam Wahyu 6:8. Bahwa dalam Wahyu 6:8, jumlah kematian yang diakibatkan malapetaka yang akan menimpa manusia seperempat penduduk bumi. Jika sekarang penduduk dunia sebanyak 7,8 miliar, berarti seperempatnya adalah 1.9 milliar. Dengan demikian nubuatan dalam Wahyu 6:8 tidak menunjuk kepada covid 19. Tetapi jika angka yang diakibatkan oleh covid 19 terus meningkat dan penemuan vaksin masih beberapa tahun ke depan, sehingga kematian manusia akibat covid 19 ini mencapai seperempat penduduk bumi, maka bisa saja covid 19 bisa merujuk kepada nubuatan dalam Wahyu 6:8.

 

ABSTRACT

_______________________________________________________________

Covid 19 has spread to almost all countries in the world. So far the death rate caused by covid 19 worldwide has reached 340,383 people. It seems that this number will continue to grow, considering the spread of this virus is so fast, spreading like wildfire. In this paper, we will analyze whether there is a relationship between the prophecies in Revelation 6: 8 and Covid 19.               To achieve this goal, the author uses a qualitative approach with an exegetical method to the text of Revelation 6: 8. From the research conducted, so far the number of deaths caused by Covid 19 is still much smaller than the number of deaths prophesied in Revelation 6: 8. That in Revelation 6: 8, the number of deaths resulting from calamities that will befall humans a quarter of the population of the earth. If now the world's population is 7.8 billion, that means a quarter is 1.9 billion. Thus the prophecy in Revelation 6: 8 does not refer to covid 19. But if the numbers caused by covid 19 continue to increase and vaccine discoveries are still a few years from now, so that human deaths due to covid 19 will reach a quarter of the earth's population, then it could be covid 19 can refer to the prophecy in Revelation 6: 8.
