Preliminary Study on the Reductive Leaching of Manganese Ores using FeSO?/Iron Powder as Reducing Agents under Room Temperature
Authors: Moro Kofi , Haubrich Frank , Martin Mirko
Published: February 2022

The leaching of manganese (Mn) ore in sulphuric acid (H2SO4) under reductive conditions has been studied. The effects of leaching parameters such as ore/reductant mass ratio, acid concentration, ore particle size, solid/liquid ratio, leaching time and different reductant potential on the maximum recovery of manganese have been investigated. The optimal leaching conditions were ore/reductant mass ratio of 1:3.4, acid concentration of 10% v/v H2SO4, ore particle size of 63-200 µm, particle size of iron powder of –150 µm, solid/liquid ratio of 1:20, and leaching time of 1.5 hours at room temperature. A comparative analysis on the recovery of manganese ore was also investigated under the optimal leaching conditions for two different reductants, iron sulphate (FeSO4) and iron powder. The maximum manganese recoveries at the optimal leaching conditions in the presence of FeSO4 and iron powder are 80.6% and 95%, respectively. The results indicate that manganese can readily be leached during short time at room temperature. Furthermore, iron powder has a stronger reducing power compared to FeSO4 with respect to manganese ore recovery.
Performance of Enhanced Steel Beam-Column Welded Connections for Seismic Resistance
Authors: Aboalriha W.
Published: February 2022

This paper presents and discusses the development of a numerical model which investigates the enhancement of overall stiffness and stress distribution in welded connections under cyclic loading. The structure under investigation, described in four fully welded T-joint (BCC5) specimens. The four specimens were modeled under different displacement loading using a finite element analysis program Solidworks and Ansys software in conjunction with test data obtained from the University of Lisbon, which was validated with the test results by matching the hysteresis loops, maximum high strain, and maximum stress at the crack location steel joint specimens. The comparison between the analysis and test results showed good agreement and also showed that the maximum strain in the enhanced model is less than the maximum strain on the base model, and the location of maximum strain is moved to the gusset plate rather than the weld zone, therefore the gusset plate makes the joint in the enhanced model more ductile than the joint in the base model. Life cycles to failure for the enhanced model are more than life cycles to failure in the base model. It is therefore found that this has useful applications in the steel construction industry.

Published: February 2022

This paper studies the stability and ground behavior of the main roadway excavated in a soft rock mass at PT Gerbang Daya Mandiri (GDM) underground coal mine in Indonesia. The stability and ground behavior of the main roadway under various geological and excavation conditions was analyzed and discussed through numerical simulations and field measurement data. Based on the results, it is found that the mechanical conditions of claystone and the geological conditions of the roof have an obvious impact on the stability of the main roadway. The large roof displacement of the roadway occurs when the roadway is excavated in the deteriorated claystone, whereas the small roof displacement occurs when the roadway excavation is made in the undeteriorated claystone and when the coal layer is present in the roof. Under undeteriorated conditions of claystone, the small failure zone and displacement of the roadway occur. The current support system using the steel arch SS400 is effective to control the roadway stability. As the claystone has deteriorated due to groundwater, the failure zone and displacement expand considerably, and the roadway stability decreases significantly. The use of the current support system (steel arch SS400) is difficult to control the stability of the main roadway. Under this situation, a stronger steel arch SS540 is recommended to apply.  Furthermore, the presence of a coal layer during the excavation considerably improves the stability of the main roadway. Compared with the roadway excavated in claystone only, the displacement decreases significantly. In addition, by leaving a thicker coal layer in the roof, a better stability condition of the roadway can be achieved.

Published: February 2022

The study was focused on investigating the impact of different washing processes (dark shade, medium shade, light shade) on various properties of denim fabric. Two different types of fabrics with twill and dobby weave constructions were produced from cotton, spandex, and polyester yarn, and different types of washing processes were applied. Dimensional stability, tensile strength, tearing strength, EPI and PPI, weight, colorfastness to rubbing, colorfastness to perspiration (acid and alkaline), and colorfastness to water was investigated and comparisons were made statistically between the before washed sample and after washed sample. It is found that the process result shows better tear and tensile strength in case of dark & medium shade wash than light shade wash. On the other hand, weight and EPI & PPI have shown better result for light wash than other wash. Colorfastness to rubbing, Colorfastness to water, and Colorfastness to perspiration (acid and alkaline medium) are similar. The shrinkage% is higher especially in the weft direction of the fabric for light wash than the dark wash.
Elemental Analysis Using Atomic Absorption Spectroscopy
Authors: Mohammed Abdul Moiz
Published: February 2022

The resonance radiation study is a powerful means in obtaining valuable information concerning the behavior of individual atoms and molecules. Various quantitative techniques are available in order to determine the amount of analyte and analysis of trace elements in the sample. Some technique uses the principle, when the number of atoms in the path of light increases, the amount of light absorption increases. While other techniques use dissociation of chemical compound free atoms by supplying enough thermal energy. In this paper, an attempt is made to compare various analytical methods with their merits and demerits and the reasons for popularity of atomic absorption spectroscopy among researchers. Elemental analysis using atomic absorption spectroscopy of various elements that are found in nature particularly in foods and environment is also presented.

Published: February 2022

In this study, a poultry egg incubator was designed, fabricated, and tested to evaluate its hatching performance. The incubator consists of a microcontroller with egg turner trays and incubating chamber of 116 nos. of egg capacity. The hatchability of the developed incubator was 79.3% and 87.1% hatchability during manual and automatic trials respectively. The temperature in the developed incubator was within the acceptable incubation temperature ranges from 37.6 °C to 38.6 °C. The average relative humidity in the developed incubator was maintained at 63.6% at manual and 55-65% at automatic trial. The eggs were turned manually approximately at 6 hours of interval. On the other hand, in the automatically controlled trial, it was done by egg turner maintaining exactly 6 hours of interval. It is noted that the percentage of hatching in rice husk incubators is below 55% which is much below comparing with the developed incubator. Also, the newborn chickens in rice husk incubators are unhealthy as they don’t get a sufficient amount of heat. Besides, in the sand incubation technique, kerosene-based hurricane lamps are used which produce Carbon Dioxide. The developed incubator is environment friendly because it doesn’t produce any by-product that is responsible for harming the environment. Also, after the successful trials, we have found the benefit-cost ratio was 1.42 which was quite satisfactory. The egg incubator can maintain the optimum conditions for the hatching of the chicken eggs and is capable of incubating and hatching the chicken eggs effectively. If the developed incubator is commercially supplied to the end-user, it will be a beneficial process of hatching for the farmer of Bangladesh.

Published: February 2022

Tomato (Lycopersicon esculentum Mill) is one of the most important and has the highest acreage of any vegetable crop in the world. Such quantitative analysis is based on the assessment of data from sequential collections of plant traits linked to environmental conditions, as well as yield potential under optimal growth conditions. The objective in this study was to evaluate the performance of tomato crop under furrow, basin and hosepipe irrigation techniques in Kabos, Serere District of Eastern Uganda. The materials and methods used in this study included tools like water pump (model DCX2-50D), Tomato variety Rionex, weighting scale, CROPWAT 8.0 software, CANOPEO software among others. Generally, quantitative techniques through several experiment designs were used. Daily and monthly weather variables, in-situ primary datasets of plant height, canopy cover percentages and fruit characteristics, and weight of harvested tomatoes were measured at three growth stages and analyzed using RCBD experiment with six treatments and four replications.

Findings showed that overhead treatments had lowest rate of rotten yield compared to basin and furrow but had highest rate of discolored fruits attributed to sunshine and impact of water pressure during irrigation. Rotting of yield was highest in basin treatments. The rotting was attributed to water logging, poor drainage that accelerated fungal infection in the tomatoes. Furrow treatments had better drainage which reduced quantity of nonmarketable yield. There was no significant difference on the weight of tomatoes below 65g. This meant that fruit weight was independent of irrigation method. Treatments under hosepipe irrigation-overhead. Conclusively, water management practices have big impact on the crop yield giving a relationship that yield is directly proportional to water management practices, which however, should be followed by detailed soil and water analysis through such studies. The Safe-Water-for Food (SWFF) target can be reached and eventually reduce on the global hunger syndrome.

Authors: Bhattacharya Ela , Mandal Mohanchandra , Bhattacharya Dipasri
Published: February 2022

Several RF sources are present for the commercial as well as defense application. In this article we will focus on the neurological consequences of Microwave Radiation (MWR). Since microwaves impact so many facets of our lives, this research focuses on their health implications. The brain is perhaps the most sensitive organ to MWR, with mitochondrial damage manifesting faster and more profoundly than in other regions. The effects of MWR on brain metabolic pathways have piqued public attention. The possibility for significant numbers of people to be subjected to dynamic, multi-frequency microwave energy nowadays, is a reality. Many urban people residing in the highrise structures of the city, come in the main beam radiation of the antenna which is mounted at a comparable height. Owing to the pervasive presence of MWR, its extensive usage, and the potential for harmful effects, comprehensive analyses of the health risks are imperative. It is crucial, therefore, to assess the level of exposure that is safe for the general population so as to minimize adverse effects despite reducing the favorable uses of microwaves.

Authors: Ojo Ochuko M.
Published: February 2022

Indiscriminate discharge of wastewater into the environment can lead to environmental pollution. Heavy metals present in wastewater can infiltrate into the ground to cause groundwater contamination. In this study, a solar still was employed in the removal of heavy metals from domestic wastewater. Five wastewater samples with high heavy metal contents were kept in a solar still and subjected to heat from the sun. The solar still was constructed using locally available materials. The concentration of Iron (Fe), Zinc (Zn), Manganese (Mn), Chromium (Cr) and Cadmium (Cd) in the untreated and treated wastewater samples were determined. The study revealed a drastic reduction in the heavy metal content of the treated wastewater, however, the heavy metal content of most of the treated wastewater samples did not fall within World Health Organization (WHO) limit for potable water. Remarkably, The Zn content of four out of the five treated wastewater samples fell within WHO limit for potable water except for sample 2 which witnessed a drastic reduction from 13.9 to 3.28 mg/L but still did not meet up with WHO limit of 3 mg/L. The treated wastewater can be safely discharged into the environment; however, further treatment is required to make the water safe for human consumption.

Overlooked Suburbs: The Changing Metropolitan Geography of Poverty in the Western United States
Authors:   Federal Reserve Bank of San Francisco, Mattiuzzi Elizabeth , Weir Margaret ,   Brown University
Published: February 2022

This report examines trends between 1990 and 2014—18 in the location of populations experiencing poverty, which we define as those with incomes below the federal poverty line, within metropolitan regions in the United States, with a particular focus on the western United States. We explore how growing suburban poverty is distributed across jurisdictional boundaries that shape governance outcomes, including incorporated and unincorporated suburbs. The size of a suburb and its incorporation status affect its position within local-regional political structures, and smaller suburbs may be overlooked by public, private, and nonprofit organizations in the community development field. Size and incorporation status also affect a suburb’s access to certain federal funds, including the Community Development Block Grant (CDBG) program, a key source of funding for local antipoverty programs. Variation in the distribution of populations experiencing poverty across census regions and metropolitan areas has implications for public and philanthropic spending on social services for low- and moderate-income populations. In this report, we first discuss average trends in the distribution of poverty across urban and suburban jurisdictions in five census regions. For comparison, we divide metropolitan areas into five geographies—the largest city in a metro area, other principal cities, large suburban cities, small suburban cities, and unincorporated areas. Next, we profile 14 metropolitan areas in the western United States through “data snapshots” showing changes in poverty rates and racial and ethnic demographics. We conclude by discussing the implications of these trends for community development practitioners seeking to promote economic participation and financial stability among low- and moderate-income communities and communities of color.
Cancer gene therapy goes viral: viral vector platforms come of age
Authors: Bezeljak Urban
Published: February 2022

Background

Since the advent of viral vector gene therapy in 1990s, cancer treatment with viral vectors promised to revolutionize the field of oncology. Notably, viral vectors offer a unique combination of efficient gene delivery and engagement of the immune system for anti-tumour response. Despite the early potential, viral vector-based cancer treatments are only recently making a big impact, most prominently as gene delivery devices in approved CAR-T cell therapies, cancer vaccines and targeted oncolytic therapeutics. To reach this broad spectrum of applications, a number of challenges have been overcome – from our understanding of cancer biology to vector design, manufacture and engineering. Here, we take an overview of viral vector usage in cancer therapy and discuss the latest advancements. We also consider production platforms that enable mainstream adoption of viral vectors for cancer gene therapy.

Conclusions

Viral vectors offer numerous opportunities in cancer therapy. Recent advances in vector production platforms open new avenues in safe and efficient viral therapeutic strategies, streamlining the transition from lab bench to bedside. As viral vectors come of age, they could become a standard tool in the cancer treatment arsenal.

Authors: Spallek Hannah , Bischoff Peter , Zhou Willi , de Terlizzi Francesca , Jakob Fabian , Kovàcs Attila
Published: February 2022

Background

Local nonsurgical tumor ablation currently represents a further option for the treatment of patients with liver tumors or metastases. Electrochemotherapy (ECT) is a welcome addition to the portfolio of local therapies. A retrospective analysis of patients with liver tumors or metastases treated with ECT is reported. Attention is given to the safety and efficacy of the treatment over time.

Patients and methods

Eighteen consecutive patients were recruited with measurable liver tumors of different histopatologic origins, mainly colorectal cancer, breast cancer, and hepatocellular cancer. They were treated with percutaneous ECT following the standard operating procedures (SOP) for ECT under general anaesthesia and muscle relaxation. Treatment planning was performed based on MRI preoperative images. The follow-up assessment included contrast-enhanced MR within at least 1–3 months after treatment and then after 5, 7, 9, 12, and 18 months until progression of the disease or death.

Results

Only mild or moderate side effects were observed after ECT. The objective response rate was 85.7% (complete response 61.9%, partial 23.8%), the mean progression-free survival (PFS) was 9.0 ± 8.2 months, and the overall survival (OS) was 11.3 ± 8.6 months. ECT performed best (PFS and OS) in lesions within 3 and 6 cm diameters (p = 0.0242, p = 0.0297)
.
The effectiveness of ECT was independent of the localization of the lesions: distant, close or adjacent to vital structures. Progression-free survival and overall survival were independent of the primary histology considered.

Conclusions

Electrochemotherapy provides an effective valuable option for the treatment of unresectable liver metastases not amenable to other ablative techniques.

PT. XYZ is a company that produces X shoes. To meet customer needs, it is necessary to design an effective and efficient production line. The problem experienced by the company is that the production target has not been achieved, which is 80 pairs per hour. The daily output that is achieved is less than the predetermined production target, so it is necessary to analyze the line balance. The purpose of this analysis is to determine the causes of not achieving production targets, to determine the value of line efficiency, balanced delay, and smoothness index for each method and to get the right proposal for the company. The research was conducted by describing precedence diagrams and collecting time data from each work element then testing and calculating the standard time, following which line balancing was carried out using the Ranked Positional Weight and Moodie-young. From the calculation results, the results obtained a better line balance using the Moodie-young method, namely, an increase in line efficiency by 27.45% from 57.67% to 85.12%, a decrease in balanced delay by 25.09% from 39.97%. to 14.88%, and a decrease in the smoothness index of 39.55 from 62.62 to 23.08. In addition, there was a decrease in the number of operators working by 2 people, from 16 operators to 14 operators and a reduction in the existing work stations (SK) by 4 SK, from 12 SK to 8 SK.

DIFFERENCES IN PERIPHERAL VASCULAR RESPONSE OF A FIBROMYALGIA PATIENT IN A PHYSICAL FATIGUE SITUATION: A CASE CONTROL REPORT
Authors: Parraça José Alberto
Published: February 2022

The aim of the present case control report was to analyze peripheral vascular response of fibromyalgia patient in an intense physical exercise fatigue situation. We analyzed a female fibromyalgia patient, 55 years, 65 kg, 156 cm, 26.7 Kg/m2, with 3 year from the fibromyalgia diagnosis and 10 year of fibromyalgia symptomatology: and a control healthy female participant, 57 years, 73 kg, 163 cm, 27.5 Kg/m2. The peripheral vascular response by thermography was collected in 3 different moments, basal, post fatigue protocol (20 repetition of knee extension and flexion of dominant leg at 180º·s-1), and after 6 min of finishing the fatigue protocol. We found how fibromyalgia patient presented a higher basal heart rate, lower skin hand temperature in basal conditions, similar in an intense exercise fatigue protocol, and lower in the recovery of the protocol than a control participant, and a higher basal skin temperature of thigh muscles in basal condition, higher in the fatigue protocol and lower in the recovery after the fatigue protocol than a control participant.

Published: February 2022

Objetivo: Estimar el consumo de drogas ilícitas [anfetamina (AMP), metanfetamina (METH), 3,4-metilendioximetanfetamina (MDMA), cannabis (THC-COOH) y cocaína (COC). Métodos: Muestras compuestas (24 horas) de efluentes de 3 plantas de tratamiento de aguas residuales (PTAR) (Deodoro, Santa Cruz, Sepetiba), ubicadas en la zona oeste, Río de Janeiro, Brasil, fueron recolectadas en 2019 y posteriormente analizadas con la técnica de aguas residuales- epidemiología basada (WBE). Resultados: Las concentraciones de COC y sus metabolitos BE, Nor-BE y CE variaron de 36 a 601ng/L; 100 a 889ng/L; 19,9ng/L y 4,68ng/L, respectivamente. Los estimulantes similares a las anfetaminas variaron de 105 ng/L para AMP, 28ng/L a 1674ng/L para METH y 4,21ng/L para MDMA. THC-COOH osciló entre 112 y 178ng/L y OH-THC 3,7ng/L. En relación con datos de consumo medio de drogas ilícitas entre 15 y 64 años (mg/día/1000 Hab) solamente AMP fue detectada en la PTAR Deodoro (41,8 mg/día/1000 Hab), en cuanto a cannabis (marihuana) y cocaína, todas las PTAR fueron positivas. Conclusión: Se observaron diferencias significativas en la detección y consumo de las drogas estudiadas y se resaltó que el uso de drogas en el área estudiada no es homogéneo, pero suscita preocupación con los posibles impactos en la salud pública.

Objetivo: Apresentar um caso de corpo estranho intraocular enfatizando o diagnóstico e tratamento tardio. Detalhamento do caso: Paciente, 71 anos, moradora de área rural, relatou perfuração do globo ocular esquerdo, socorrida em unidade de saúde onde realizaram sutura na córnea. Aproximadamente 131 dias, após sofrer a injúria foi encaminhada ao nosso serviço com queixa de baixa acuidade visual do Olho Esquerdo (OE). Ao exame oftalmológico verificou-se acuidade visual com correção em Olho Direito (OD) 20/20 e OE somente percepção luminosa. À biomicroscopia do OD sem alterações, no OE apresentava cicatriz corneana, leucoma central estendendo até a periferia temporal mostrando a porta de entrada do Corpo Estranho (CE), lesão e suturas na córnea, hiperemia conjuntival e pelo aspecto clínico caracterizando uma episclerite nodular. O cristalino apresentava opacidade central com pigmento de íris. À ultrassonografia do OE, evidenciou massa hiper-reflexiva, pico acústico alto, sugerindo Corpo Estranho Intraocular (CEIO). Considerações finais: Após o diagnóstico, a paciente foi encaminhada para cirurgias e remoção do CE. Assim, deve-se sempre anteceder ao ato terapêutico com exames de imagens capazes de permitirem a correta localização e dimensionamento do CE, para garantir adequado planejamento terapêutico e cirúrgico, de forma que o prejuízo à visão seja reduzido.
Pemberton’s acetabuloplasty without cast application for the treatment of acetabular dysplasia in older children: A case series
Authors: Kremli Mamon K. , Ismael Fikri A. F. , Al Mohaini Reem A. , Kremli Asmaa M.
Published: February 2022

Objectives:

To study the safety and efficacy of performing Pemberton’s acetabuloplasty (PA) in older children without application of post-operative cast to avoid the restriction and complications of cast in older children.

Methods:

Patients who had acetabular dysplasia and underwent Pemberton’s acetabuloplasty without cast during the period 1999-2021 were selected for the study. Cases were followed until radiographic healing of the osteotomy.

Results:

Twenty patients (22 hips) were included in the study. Primary acetabular dysplasia was recently discovered because of pain in 10 patients; the other 10 had residual acetabular dysplasia after treatment of developmental hip dysplasia (DDH). Most patients (19 hips in 18 patients) had a PA without internal fixation and post-operative cast. Two patients had an internal fixation with a cannulated screw because of concern about compliance with non/toe-touch weight-bearing post-operatively. The mean age on the time of surgery was 10.4 years (6.5–15.5 years). The mean body weight on the day of surgery was 42.8 Kg. (30-66 Kg.). The mean postoperative follow-up was 38 months (three months – 14 years). All patients were able to walk using a walker within five days after surgery. The follow-up radiographs showed no graft collapse and no displacement of the graft or osteotomy. Correction of the acetabular dysplasia and corrected Shenton’s line were confirmed on the last follow-up with no re-dislocation or re-subluxation of the hip.

Conclusion:

Performing Pemberton’s acetabuloplsty in older children without application of post-opertaive cast is efficient and safe. Complications of cast and the gross limitation it has on daily living activities and mobilization are all avoided without compromising the surgical results and healing. Care should be taken to ensure that patients and caregivers clearly understand the importance of non/toe-touch weight-bearing post-operatively and are compliant.
From a dysembryoplastic neuroepithelial tumor to a glioblastoma multiforme: Pitfalls of initial diagnosis on biopsy material, a case report

Published: February 2022

Background:

Ganglioglioma (GG) and dysembryoplastic neuroepithelial tumor (DNET) belong to the group of low-grade epilepsy-associated tumors (LEAT) and are the most prevalent tumor types found in patients undergoing epilepsy surgery. Histopathological differentiation between GG and DNET can be difficult on biopsies due to limited tumor tissue.

Case Description:

Here, we present a rare case where a low-grade tumor was initially classified as DNET, based on biopsy findings and unfortunately dedifferentiated within 10 years into a glioblastoma multiforme. After gross total resection, the initial tumor was reclassified as GG.

Conclusion:

This case illustrates the diagnostic challenges of LEAT, especially on biopsy material. Therefore, we advocate to counsel for complete resection and histopathological diagnosis utilizing tumor markers to confirm the nature of the tumor and to advice type of follow-up and eventual concurrent treatment.
Remote neuro-endovascular consultation using a secure telemedicine system: A feasibility study
Authors: Ishibashi Toshihiro , Kaku Shogo , Sonoda Shota , Murayama Yuichi
Published: February 2022

Background:

Telemedicine has been rapidly implemented under COVID-19 conditions, to assess the ability to use an audio-visual telemedicine system for neuro-endovascular remote consultation.

Methods:

The system consists of a live streaming function for angiography and an operating room (OR) camera using a smartphone application (JOIN; Allm Inc, Tokyo, Japan) in conjunction with verbal communication using the Zoom app. The system allows us to display multiple angiographic images in addition to streaming video from the 4K camera recording the operator’s procedure and from the 4K camera showing the OR view on the monitor of any smart device.

Results:

The operator was able to speak with the senior supervisor through a bone conduction headphone and to talk to assistants or radiology technicians without any hearing difficulties. The remote supervisor was able to check the streaming images, which had almost the same imaging quality as real digital subtraction angiogram (DSA) monitors, and he could advise the handling of devices and preparation through the 4K video camera systems. The DSA image delay was within 2 s.

Conclusion:

A remote consultation system with real-time audio-visual capability may play an important role in acute stroke management and maintain the quality of patient care under COVID-19 conditions.
