Influence of Particle Size and Particle Range Distribution on the Microstructure of Al–Mg–Si/PKSA Composite for Amateur Solid Rocket Chamber
Authors: Oyedeji Elijah O , Dauda Muhammed , Yaro Shehu A , Abdulwahab Malik
Published: April 2021

The study discusses an overview of small rocket program, development and characterization of locally sourced material at low cost. The aim is to enable the construction of small sounding rocket components for experimental purposes in Nigeria. This paper proposes the utilization of palm kernel shell ash as filler materials in the development, characterization and production of composite material to construct prototype reusable chamber and accessories that will enable it possible for small scientific experiments. To achieve this, particle size and particle range distribution on the microstructure, texture, and mechanical properties of (Al–Mg–Si)/PKSA composites developed by powder metallurgy method were investigated. The access in the 6xxx series of aluminum-magnesium-silicon alloy was investigated for this reason. ImageJ software was used to do particle size analysis professionally and the software was used to calculate the area, mean, standard deviation (SD) and the pixel values. The particle size distribution of big constituent (densification or rather densified solids) particles and small dispersoids possess a finer and slightly elongated grain structure when compared with the unreinforced alloy. The results of the XRD and XRF of all the samples considered showed that Al2O3, SiO2, Mn2O3 and MgO phases were common to all. These hard phases are considered to be responsible for improved mechanical properties and resistance of the composite, while the SEM result showed that the reinforcement was uniformly distributed which further improves the mechanical property of the composite.Keywords:  Microstructure, Composite, Rocket, Palm Kernel
Adaptive Power Control with Selection Combiner over Nakagami-m Fading Channel
Authors: Abolade Robert O , Oyedokun O O , Ojo Samson I , Adeyemo Zachaeus K , Ojerinde I A
Published: April 2021

Acceptable Quality of Service (QoS) is of paramount importance in wireless communication system. However, QoS is affected by multipath propagation resulting in unreliable reception. Selection Combiner (SC) which is one of the techniques previously used to solve this problem is associated with poor performance due to fixed power level used in the technique. Hence, in this paper, an Adaptive Power Control (APC) technique using SC with a closed form expression over Nakagami-m Fading Channel is proposed. APC technique is developed using fixed power SC and Link Adaptation Algorithm (LAA). Ten thousand (10,000) bits are randomly generated and modulated using Quadrature Amplitude Modulation (QAM) scheme. The modulated signal is passed through the Square Root Raised Cosine (SRRC) filter for suitable transmission over the Nakagami-m fading channel. The faded signals at varying paths ‘L’ (2, 3, 4) are selected by Conventional Selection Combining (CSC) to instruct the transmitter for adjustment of power level based on the value of the received signal through LAA. Mathematical expression for the received signal using Probability Density Function (PDF) of Nakagami-m Fading Channel at varying paths is derived. The APC technique is simulated using MATLAB software and evaluated using Signal to Noise Ratio (SNR), Outage Probability (OP) and Bit Error Rate (BER) to determine the performance of the proposed technique. OP values of 0.0969 and 0.1069 are obtained for APC and CSC, respectively, at SNR of 6 dB with L of 4, while BER values of 0.0052 and 0.2599 are obtained for APC and CSC, respectively. The percentage reduction in OP and BER are 29.79% and 54.43%, respectively. The results obtained show that APC gives lower OP and BER values with increase in SNR when compared with fixed power SC due to self-adjustment of the allocated power. Therefore, the APC technique proposed can be used to enhance the performance of wireless communication systems. Keywords— Adaptive Power Control (APC), Selection Combiner (SC), Link Adaptation Algorithm (LAA), Bit Error Rate (BER), Outage Probability (OP), Probability Density Function (PDF) and Diversity Combiner (DC).

Published: April 2021

A previously healthy woman, aged 32 years, presented to the oncology clinic with a 6-month history of left-breast tumor, mastalgia, and swollen axillary nodes. Physical examination was relevant for a 6-cm palpable mass in the upper outer quadrant of the left breast and an ipsilateral 2-cm, nonfixed axillary lymph node. Mammography showed a 1-cm mass in the upper outer quadrant, a 5.2-cm mass in the lower outer quadrant, and enlarged pathologic lymph nodes (BI-RADS category 5 disease). Breast ultrasound revealed 3 axillary lymph nodes with cortical thickening and loss of normal morphology (the largest with a 2.6-cm length in the long axis) (Figure 1A-B). The breast's core biopsy revealed a grade 3 apocrine invasive carcinoma with lymphovascular invasion; immunohistochemistry testing showed HER2-negative, hormone receptor-negative disease (estrogen receptor, 0%; progesterone receptor, 0%; HER2-negative, Ki67, 50%) (Figure 2A-B). A fine-needle aspiration biopsy of the axillary lymph nodes showed invasive breast carcinoma as well. Bone scintigraphy and a chest/abdomen CT scan ruled out metastatic disease. Upon initial diagnosis, clinical stage was deemed as cT3N1M0 (American Joint Committee on Cancer 8th edition: anatomic stage IIIA, clinical prognostic stage IIIC).

After a multidisciplinary tumor board discussion, the patient underwent neoadjuvant chemotherapy with weekly paclitaxel, followed by 4 cycles of dosedense doxorubicin plus cyclophosphamide. After completing neoadjuvant treatment, clinical examination was relevant for a residual 1-cm palpable left breast mass and no palpable axillary nodes. Mammography and breast ultrasound showed a 77% partial response in the primary tumors, and axillary nodes with normal morphology and size (Figure 1C-D). Due to multicentric tumor disease, breast-conserving surgery would not confer satisfactory cosmetic results on her, and a modifi ed radical mastectomy with intraoperative sentinel lymph node biopsy (and second-stage breast reconstruction) was planned. However, during surgery, the surgeons failed to identify the mapped lymph node, and level I-III axillary lymph node dissection was performed. The pathology report described complete pathological response: Miller and Payne criteria grade 5 response with the absence of malignant cells within the mastectomy specimen and in 24 lymph nodes (Figure 2C-E). Pathological staging after neoadjuvant treatment concluded ypT0N0M0 disease. Subsequent treatment for this patient was discussed in another tumor board.

Published: April 2021

Acne vulgaris is a chronic inflammatory disorder of the pilo-sebaceous follicles characterised by comedones, papules, pustules, nodules and often scars mainly seen on cheeks, chin, nose, forehead and upper trunk during adolescence. The symptoms of Acne vulgaris resemble Mukhadushika as per Ayurvedic classics. Acharya Sushruta has mentioned Mukhadushika as one of the Kshudra Rogas. In Mukhadushika, there are Shalmali kantak like eruptions on the face which are impregnated with Meda caused due to vitiation of Kaphadosha, Vatadosha and Raktadhatu which destroy the beauty of the face and makes the appearance ugly. The disease almost take place in adolescent and young age group prominently therefore is also known as Yuvanapidika. Acharya Sushruta stated Jalaukavacharana is the preferred method of bloodletting in Sukumara. Aim: To evaluate the efficacy of Jalaukavacharana in the management of Acne vulgaris w.s.r. to Mukhadushika. Methodology: Fourteen patients of age group 15-30 years having signs and symptoms of Mukhadushika were selected and four sittings of Jalaukavacharana on a seven day interval were given. Apart from treatment duration of 28 days, a follow-up was also done after 30 days. Results: Intervention was found to be highly significant (p<0.001) in Vedana, Kandu, Daha, number of Pidika, size of Pidika, Pidika ghanata, Shotha, Vaivarnyata. However, significant effect (p<0.05) was found in Vranavastu and non-significant result (p>0.05) was found in Srava. Conclusion: The results are satisfactory.

Extracellular vesicles – developmental messengers of tissue crosstalk
Authors: Witte Leonie , Gross Julia Christina
Published: April 2021

Extracellular vesicles are membrane particles secreted from cells into all body fluids. They convey signals that induce long-term changes in cellular behavior. During development, EV secretion and the specific loading of signalling factors in EVs contributes to organ development and tissue differentiation. Different biomolecules such as proteins, lipids and nucleic acids transmit these signals and the content, size, and membrane composition of EVs are highly dynamic and depend on the cellular source, state, and environmental conditions.Here we review current in vivo studies in different model organisms regarding extracellular vesicles and their physiological role in the formation of cell types, tissues and refined body structures.

HYPOTHESES AND ETHICS IN THE TIME OF THE COVID-19 PANDEMIC
INFECTION-ACQUIRED VERSUS VACCINE-INDUCED IMMUNITY AGAINST COVID-19
Authors: Velikova Tsvetelina
Published: April 2021

The course of COVID-19 depends on a dynamic interplay between SARS-CoV-2 and the host's immune system. Although it is an emerging global health issue, little is known about the specificity, safety, and duration of the immunity elicited by the virus. This hypothesis article explores the benefits of infection-acquired and vaccine-induced immunity against COVID-19, suggesting that the latter outweighs the former. Comparative studies are proposed to explain and reveal all aspects of the immune responses. Although vaccine development relies on studies of naturally acquired immune responses, there are still no comparative analyses of the natural and vaccine immunity against SARS-CoV-2. Moreover, there are scarce reports on the characteristics of both types of responses. The scientific facts about the virulence of SARS-CoV-2 affecting the immune system are of great importance for proposed comparative analyses. Various immunological methods can be employed to elucidate infection-acquired and vaccine-induced immunity against SARS-CoV-2. The safe vaccination of subjects with and without COVID-19 history may disrupt the virus spreading and end the pandemic.
SPERMIDINE MAINTAINS TELOMERE LENGTH AND DELAYS AGING
Authors: Sharma Priyanka , Jaiswal Rishi Kumar
Published: April 2021

Spermidine, a natural polyamine, has been noticed for its anti-aging properties. Supplementation of this drug prolongs lifespan and diminishes the incidence of age-related pathology. In the human population, spermidine levels decrease as aging progresses, and a potential link between diminished endogenous spermidine levels and age-related declination has been studied. At the cellular level, autophagy is the prime mode of action of spermidine known to decline with the progress of aging, similarly contributing to the accretion of impaired macromolecules and organelles through aging. Epidemiological statistics support the concept, suggesting that elevated uptake of polyamine delays aging. Here, we overview the effect of autophagy on cellular processes and age-associated diseases, emphasizing the importance of these events to the hallmarks of aging.

There are numerous factors like shortening telomere, oxidative stress, mitochondrial damage, and impaired intracellular calcium signaling, which are influenced by the aging process. We hypothesize that spermidine supplements in the diet increase the telomere length. The proposed hypothesis also brings to light the differentially regulated genes involved in telomere maintenance and aging after spermidine treatment. Knowing the role of spermidine in telomere maintenance would help us understand the molecular mechanism of spermidine's effect on aging.

A batata yacon (Smallanthus sonchifolia) vem sendo utilizada empiricamente para auxiliar na redução da resistência insulínica bem como no tratamento de Diabetes Mellitus. O número de indivíduos com diabetes está aumentando devido ao envelhecimento populacional, à maior urbanização, à crescente prevalência de obesidade e ao sedentarismo. Diante disso, este estudo teve por objetivo avaliar o efeito da batata yacon sobre os parâmetros glicêmicos de idosos de uma instituição asilar do município de Itajaí/Santa Catarina, após 5 semanas de intervenção com batata yacon in natura adicionada ao suco de frutas. Foram utilizadas 24 g de batata yacon, equivalente a 7,7g de frutooligossacarídeos, distribuídos uma vez ao dia a cada participante, sendo 12 do Grupo I (com diabetes e resistência à Insulina) e 11 do Grupo II (sem resistência à insulina e sem diabetes). Para determinação do controle glicêmico, foram realizados exames laboratoriais de hemoglobina glicada, frutosamina, glicemia e insulina de jejum antes e após a intervenção. O resultado de hemoglobina glicada foi significativamente menor nos dois grupos, a frutosamina apresentou aumento significativo apenas no Grupo II, enquanto as concentrações de glicemia e insulina de jejum permaneceram semelhantes nos dois momentos do estudo. As medidas antropométricas não sofreram alterações em ambos os grupos. Conclui-se que a batata yacon diminuiu as concentrações de hemoglobina glicada no sangue, no entanto este resultado foi conflitante com os valores de frutosamina e glicemia de jejum.

Salicin a promising ER, PR and HER2 binding molecule proving lethal against Hormone + and triple negative breast cancer cells
Authors: Vekaria Mrudul Pravinbhai , Tirgar Pravin
Published: April 2021

Therapeutics against breast cancer is a major research field, due to inefficiency or partial efficiency of existing therapeutics.  An urge to discover better therapeutics always persists. Our objective is to study salicin against breast cancer cells, in order to find its therapeutic properties. To study the effect of salicin on breast cancer cells, we performed MTT assay on MCF-7 (hormone positive) and MDA-MB-231 (triple negative) breast cancer cell lines, we did brine shrimp lethality test (BSLT) assay to see the lethal effects of salicin. By the help of bioinformatics we tried to locate the targets that delineate salicin activity. Salicin was docked with estrogen receptor (ER), progesterone receptor (PR) and Human epidermal growth factor receptor 2 (HER2) to study its binding efficiency and possible targets of salicin. Salicin remarkably reduces cell viability both in MCF-7 and MDA-MB-231, along with being lethal to brine shrimps. These results together opine that salicin can be an effective therapeutics against breast cancer cells. The mechanism of action of salicin is probably through ER, PR and HER2 receptors because it can efficiently bind these receptors with minimum energy required for binding. This explains that salicin can easily bind to these receptors. These results together opine that salicin can be an effective therapeutics against breast cancer cells. The mechanism of action of salicin is probably through ER, PR and HER2 receptors because it can efficiently bind these receptors with minimum binding energy. ER, PR and HER2 are major reasons behind the disease pathogenicity depending on the type of breast cancer. According to our results salicin may either induce apoptosis or reduce cellular mitosis both via P53 dependent and independent pathway, which makes salicin a good choice of both hormone positive and negative breast cancer cells.

A House in Germany
Authors: Bate David
Published: April 2021

We used to believe that photographs always “refer” to something beyond themselves that already exists, like an actual place, space, object or person(s). Even though this was never always true or completely convincing, such strongly held convictions have been profoundly shaken by the effects of popular digital culture. It is no longer a matter of any specific photograph itself being unreliable, so much as the whole edifice of social and cultural life, and its media platforms, being taken over by a pervading sense of doubt.

The idea and belief that photographs invoke a presence is increasingly compromised by the haunting sense of an absence. As explored in this work, a house in Germany is the site of a machinic vision, whose “consciousness” is implanted as an instrument of human vision.
Photographing a miraculous apparition in fin-de-siècle France
Authors: Gizzi Ferdinando
Published: April 2021

This paper is dedicated to the photographic coverage of the alleged miraculous apparitions, which occurred in the small French village of Tilly-sur-Seulles between 1896 and 1897. These photos, circulated as postcards and appearing in popular magazines of the time such as L’Illustration and Le Monde illustré, were presented – by virtue of the authority of the photographic as an indexical trace – as “authentic” testimonials of the supernatural events, though in fact neither recognized nor approved by the Catholic Church. These photographs used the already-known double exposure process of spirit photography, bringing these exotic visual materials into the tradition of religious “authentic fakes”. But more importantly, such images manifested the “visionary fervour” of late nineteenth-century France, that is, the growing desire of the modern crowd to see the invisible in more and more spectacular and convincing ways. Such a new spectatorial desire – that can also be found in the very successful genre of the photographs of the real bodies of mystics, saints, and seers – would be perfected by a whole series of contemporary forms and attractions, and finally, by cinematographic special effects.

Background: With the advent of modern radiologic imaging there is increase in the detection of pituitary lesions in imaging done for others non-related lesion. The aim of this review is to report our first case of pituitary incidentaloma in a patient who was evaluated for chronic subdural haematoma Case Presentation: A 65-year-old known hypertensive presented initially to the internal physicians with severe headache, change in sensorium and right sided weakness. He has had history of a fall 6 weeks prior to presentation. His Glasgow coma scale score was 14/15 (E4V4M6). The power on his right upper and lower limbs was 3/5 and on the left limbs was 5/5. He had global exaggerated reflexes and hypertonia. Computerized Tomographic (CT) Scan of the brain done showed massive left subdural haematoma and 14 by 12 by 15 sellar mass. (Figure 1) Pituitary hormonal assay showed decrease in cortisol and other pituitary hormones with slight increase in prolactin. He subsequently had unilateral double burr hole and drainage. He did very well and was discharged 2 days after surgery. At his first follow up visit he was offered the option for further evaluation and treatment of the pituitary lesion but he declined due to financial constraints. Conclusion: Incidental finding of pituitary tumour is a reality in our setting. A lot need to be done to make modern radiological imaging readily available and affordable to increase yield.

The Correlation between The Frequency of Breast Care and The Smooth Production of Breast Milk on Day 4 Postpartum

 Abtract.Breastmilk provides all the energy and butrition a baby needs for the first 6 months of baby life. The firts six months only exclusive breastfeeding is provided for babies without any additional food or drink. This study aims to analyze the correlation between the breast care frequency and the smooth production of breastmilk in post-partum mothers on day 4. The research method was observational analytic with a cross-sectional approach. The study population was all-day 4 postpartum mothers and the study sample were some of the fourth days' postpartum mothers at BPS Asri and Polindes Permata Bunda Tuban in March-April 2020. The research sampling was simple random sampling. The independent variable was the frequency of breast care, while the dependent variable was the milk production smoothness. Data analysis used the Spearman correlation with significant limits of p-value <0.05. The analysis of the results showed a p-value=0.000, which means that there was a correlation between the breast care frequency and the breastmilk smooth production in postpartum mothers on day 4. The importance of breastfeeding for babies is that postpartum mothers are expected to always maintain the smooth running of breast milk by doing regular and correct breast care.

Analisis Perilaku Percobaan Bunuh Diri pada Klien Skizofrenia dengan Pendekatan Model Adaptasi Roy: Studi Kasus
Authors: Budiarto Eka
Published: April 2021

Abstrak. Bunuh diri merupakan respon maladaptif dari rentang respon protektif diri. Bunuh diri terjadi sebagai akibat dari stress dan depresi yang disebabkan faktor psikososial yaitu kepribadian, psikodinamika, kegagalan yang berulang, faktor kognitif, dukungan sosial, pengalaman masa lalu, dan stressor lingkungan. Model adaptasi Roy memandang manusia sebagai makhluk biopsikososial dan memiliki permasalahan yang menuntut manusia beradaptasi dengan masalah tersebut. Tujuan penulisan artikel ini adalah memperoleh penjelasan empiris dan teoris terhadap faktor psikososial kaitannya dengan perilaku resiko bunuh diri. Studi kasus ini menggunakan metode deskriptif pada kasus kelolaan di rumah sakit jiwa. Pengelolaan stress yang adapatif merupakan upaya preventif terhadap perilaku resiko bunuh diri. Perilaku bunuh diri tidak akan terjadi apabila individu dapat menggunakan mekanisme koping adaptif yang didukung oleh sosial support, hubungan interpersonal, dan kemampuan memilih strategi koping sebagai faktor protektor. Perawat dalam mengelola klien dengan riwayat bunuh diri harus melibatkan keluarga dan masyarakat untuk mengoptimalkan penggunaan faktor protektor tersebut.  Kata kunci: Adaptasi Roy, Depresi, Perilaku Bunih Diri, Psikososial, Stress

 Behavior Analysis of Suicide Experiment with Roy's Adaptation Model Approach:

Case study

Abstract. Suicide is a maladaptive response of a range of self-protective responses. Suicide occurs as a result of stress and depression caused by psychosocial factors such as personality, psychodynamics, repetitive failure, cognitive factors, social support, past experiences, and environmental stressors. Roy's adaptation model regards the humans as biopsychosocial beings and has problems that demand the humans to adapt the problem. The purpose of this article is to obtain the empirical and theoretical explanations of psychosocial factors related to suicidal risk behavior. This case study uses descriptive methods in cases of management in a mental hospital. Adapatif stress management is a preventive effort against suicidal risk behavior. Suicidal behavior will not occur if individuals can use adaptive coping mechanisms supported by social support, interpersonal relationships, and ability to choose coping strategies as a protector factor. Nurses in managing clients with a history of suicide should involve families and communities to optimize the use of these protector factors.

Artificial Intelligence(AI) and Internet of Things(IoT) are popular domains in Computer Science. AIoT converges AI and IoT, thereby applying AI into IoT. When ‘things’ are programmed and connected to the Internet, IoT comes into place. But when these IoT systems, can analyze data and have decision-making potential without human intervention, AIoT is achieved. AI powers IoT through Decision-Making and Machine Learning, IoT powers AI through data exchange and connectivity. With the AI’s brain and IoT’s body, the systems can have shot-up efficiency, performance and learning from user interactions. Some studies show that, by 2022, AIoT devices such as drones to save rainforests or fully automated cars, would be ruling the computer industries. The paper discusses AIoT at a greater depth, focuses on few case studies of AIoT for better understanding on practical levels, and lastly, proposes an idea for a model which suggests food through emotion analysis.

In this study, a new composite of nZVI/(Fe - Mn) binary oxide/bentonite (IFMB) was synthesized and used as an adsorbent for the removal of reactive yellow 145 dye (RY- 145) from aqueous solution. Optimization of composition of IFMB composite for removal of RY - 145 dye was conducted with the help of surface response method (SRM). Three independent variables affecting to the RY-145 adsorption efficiency were selected for optimization study: Fe/Mn ratio (mol/mol), Bentonite content (wt. %) and nZVI content (wt. %). The study reveals that optimal compositions of IFMB composite for RY-145 removal was Fe/Mn = 1,75; Bentonite 9,46 wt. % and nZVI 16,97 wt. %. In the adsorption condition: adsorbent dose  of 1g.L-1, initial dye concentration of 200 mg.L-1, contact time of 120 min at 120 rpm and at 25 oC, the adsorption capacity for RY-145 dye on IMFB composite is 197 mg.g-1. The value of RY-145 adsorption efficiency calculated by the model at the optimal point has been compared with the experimental value and the error is very small (0,36%). This proves that the RSM model has good repeatability.

A theoretical study on the influence of non-metal (B, C, N, O, F) doping on the electronic and optical properties of graphitic carbon nitride (g-C3N4)
Authors: Nguyen Thi Thu Ha  , Nguyen Ngoc Ha
Published: April 2021

A robust and accurate tight-binding quantum chemical method (GFN2-xTB) was performed to study the electronic and optical properties of graphitic carbon nitride (g-C3N4) and g-C3N4 modified with non-metal atom (B, C, N, O, F). The vertical ionization potential, electron affinity and global electrophilicity indexes were calculated and analyzed. The obtained results show that the doping of B, C, N, O or F atom onto the surface g-C3N4 is favorable in terms of formation energy. The introduction of non-metal atoms raises the Lewis acidity of g-C3N4. The calculated UV-VIS spectra show that the doping of non-metal atoms increases the absorption intensity of visible light compared to the pure g-C3N4.
