Vernonia amygdalina is a member of the Asteraceae family and a shrub of 2-3m tall with a petiole leaf of about 6mm wide and naturally distributed in many parts of West Africa. It is reported to have several health benefits including antimicrobial efficacy. The study assessed the antimicrobial effects of aqueous and ethanolic extracts of Vernonia amygdalina on clinical isolates of Escherichia coli and Proteus spp. Of the 41 urine samples collected included in this research, 21 clinical samples (urine) were collected from Kwararafa Hospital Wukari while the remaining 20 samples were taken from students of Federal University Wukari. Standard microbiological techniques were employed in this investigation. Extracts of the leaves were made using Ethanol and aqueous procedures. The antimicrobial activity of the extracts was tested using pathogenic isolates of Proteus species and Escherichia coli. It was observed that Escherichia coli were susceptible to both extracts of the leaf in high concentrations. The aqueous extract of the leaf shows moderate growth on the Proteus species but the ethanolic extract of the leaf presented significant antimicrobial activity on Proteus spp. This study has revealed greatly that extracts of Vernonia amygdalina in high concentration possess strong antimicrobial activities against the tested clinical isolates Proteus species and Escherichia coli with ethanolic extract of the leaves exhibiting greater antimicrobial significance against the tested clinical isolates compared to aqueous extracts of the leaves.

Physical education facilities and infrastructure is one of the elements supporting the success of physical education learning. The need for physical education learning facilities and infrastructure is very vital, meaning that physical education must use facilities and infrastructure according to needs. In fact, it was found that physical education learning facilities and infrastructure were adequate and tended to be lacking. Physical education facilities are media or teaching aids in physical education. The infrastructure itself is divided into two, namely infrastructure or tools and infrastructure or facilities. Ideally, this tool should not be moved so that it is not easily damaged unless the space is limited so it must always be disassembled. Then infrastructure or facilities are everything that is needed in physical education learning, is permanent or cannot be moved.
The research used in this research is survey research. This research does not test hypotheses or does not use hypotheses, but only describes what information is in accordance with the variables studied. The subjects in this study were SD Negeri 1-7 in Batursari Village, Mranggen District, Demak Regency.
The results of the calculation explain that the total number, condition and ownership of facilities and infrastructure is SD N 1 Batursari is a school that totals all of the number, condition and ownership of facilities and infrastructure in the high category compared to other schools. Schools in the medium category are SD N 2 Batursari, SD N 5 Batursari, SD N 6 Batursari and SD N 7 Batursari. Schools in the low category are SD N 3 Batursari and SD N 4 Batursari.
Based on the results of research and data on physical education facilities and infrastructure in State Elementary Schools in Batursari Village, Mranggen District, Demak Regency, only a small part of the physical education facilities and infrastructure owned by each school, most of the facilities and infrastructure are still in good condition and ownership status of all facilities and infrastructure are their own.

Published: August 2021

Education is a very complex activity. Almost all dimensions of human life are seen in the educational process, either directly or indirectly. Under no circumstances can humans resist the effects of implementing education. Education is also a process in which it finds transformation both within oneself and in the community. Therefore, the correct educational process is to free a person from various confines, intimidation and exploitation. This is a portrait of the world of education which is increasingly concerning, even disturbing many people. This situation implies that the dehumanization of school education becomes something that cannot be separated from life, education seems to be the ghost of society. The dehumanization of education, to borrow Paulo Freire's term, is education that oppresses, curbs, and shackles the subject of learning, both the learner and the teacher himself. The context of the research in this scientific work is to discuss the principle of freedom of learning of Imam Al-Ghazali and how the principle of the system among Ki Hajar Dewanatara's perspective.

This research is a library research (Library Research), by discussing the principle of freedom of learning by Imam Al-Ghazali and how the principle of the system among Ki Hajar Dewanatara's perspective. Data collection was carried out with yellow books and books, journals, theses, and other scientific works related to the above discussion. Data analysis is carried out by discussing content (content analysis) which is sometimes found in books and books. Check the validity of the data is done with Credibility (Credibilty).

The results of this study indicate that: The basic principle of Imam Al-Ghazali's freedom of learning can be interpreted as a conscious effort that leads to the creation of outer and inner behavior to do good and stay away from evil, to have a complete personality both to himself or to others. And also in the principle of the Among Ki Hajar Dewantara system in the implementation of learning at Ki Hajar Dewantara's school, using the "Among System". In the Among System, every teacher (pamong) as a leader in the educational process is required to behave: Ing Ngarsa Sun Tuladha, Ing Madya Mangun Kasra, Tut Wuri Handhayani.

Published: August 2021

Background: Misoprostol is a synthetic prostaglandin E1 analogue, used for the management of miscarriages and labour. Castor oil is a natural plant extract that has been reported to have some abortifacient Properties Objectives: This study investigated the labour induction and abortifacient properties of castor oil, as well as possible effects on the electrolytes and hormones that regulate pregnancy, as well as to compare these effects with a standard labour inducing drug misoprostol, in Wistar rats. Methods: The study was conducted out in 2 phases. The pregnant rats were administered varying Castor oil doses of low (12.4ml/kg), medium (18.6ml/kg) and high (24.8ml/kg), which were compared with misoprostol group as well as a control group. All animals were euthanized on gestational day 15 and day 20 respectively for the two phases and blood samples collected via cardiac puncture from the apex of the heart for hormonal assay, electrolyte and kidney function tests. The uterus was also removed for histological processing. Results: The abortifacient effect of castor oil is dose dependent with high dose castor oil group seen to have significantly reduced serum progesterone level (32.8±4.25 and 40.8±0.70 compared with 51.0±2.00 of controls), resulted in weight loss and interference with kidney function (increase in serum potassium while decrease in sodium electrolytes). Castor oil also exhibited labor inducing properties. Conclusion: Castor oil has the potential to induce abortion. This study has demonstrated a possible usage of castor oil in medical induction of labor in rats as it exerted uterotonic principle on the uterus.

Fractal Markets, Frontiers, and Factors
Authors: Berghorn Wilhelm , Schulz Martin T. , Otto Sascha
Published: September 2021

We develop an alternative view to the modern finance theory that essentially suggests equilibria in efficient markets by taking a risk-based view of asset returns in stock markets. Based on a mathematical analysis of stock market data using multi-scale approaches, we will alternatively describe markets and factors as trend-based fractal processes and analyze well-known factor premiums, which leads to a return-based view of markets and a model of investors reacting to market environments. We conclude that markets could be viewed alternatively as fractal, non-stationary and, at most, asymptotically efficient.
Evidence collected for peer review of buckling-restrained braced frames in New Zealand
Authors: Court-Patience Dan , Garnich Mark
Published: September 2021

Buckling-restrained braces (BRBs) form a bracing system that provides lateral strength and stiffness to a building. These systems have been shown to provide larger energy dissipation in severe earthquake events compared to concentrically and eccentrically braced frames (CBFs and EBFs). However, unlike CBFs and EBFs there is no guidance document or specific instructions in regulatory standards for the design of buckling-restrained braced frames (BRBFs) in New Zealand. This makes it difficult for structural engineers to be aware of all the strength and stability considerations required for the safe design of BRBFs. Currently, structural designs that include BRBFs require a peer-review to gain building compliance. The American standard ANSI/AISC 341-16 is the adopted document used in New Zealand for guidance in how to collect evidence showing a BRBF system will perform as intended. However, as ANSI/AISC 341-16 is not a governing document in New Zealand, instructions within the document are not enforced and can be made to fit within the constraints of a building project. By way of example, this paper presents the experimental test process and results acquired from pre-qualification testing of three different commercially available BRB architypes. Of the three BRB designs investigated, one failed prematurely due to global buckling. A manufacturing error was the likely cause of this premature failure. This failure highlights the need for strict quality control during fabrication. All remaining BRBs performed well, meeting the acceptance criteria set out in ANSI/AISC 341-16. Positive pre-qualification results meant the BRBs were installed in medium to high-rise buildings throughout New Zealand. The importance of sub-assemblage testing to assess the performance of a BRB and its frame components is also discussed. Finally, the capability of high fidelity modelling to supplemental physical testing is also presented.
Design recommendations to prevent global out-of-plane instability of rectangular reinforced concrete ductile walls
Authors: Dashti Farhad , Dhakal Rajesh , Pampanin Stefano
Published: September 2021

Observations of out-of-plane (OOP) instability in the 2010 Chile earthquake and in the 2011 Christchurch earthquake resulted in concerns about the current design provisions of structural walls. This mode of failure was previously observed in the experimental response of some wall specimens subjected to in-plane loading. Therefore, the postulations proposed for prediction of the limit states corresponding to OOP instability of rectangular walls are generally based on stability analysis under in-plane loading only. These approaches address stability of a cracked wall section when subjected to compression, thereby considering the level of residual strain developed in the reinforcement as the parameter that prevents timely crack closure of the wall section and induces stability failure. The New Zealand code requirements addressing the OOP instability of structural walls are based on the assumptions used in the literature and the analytical methods proposed for mathematical determination of the critical strain values. In this study, a parametric study is conducted using a numerical model capable of simulating OOP instability of rectangular walls to evaluate sensitivity of the OOP response of rectangular walls to variation of different parameters identified to be governing this failure mechanism. The effects of wall slenderness (unsupported height-to-thickness) ratio, longitudinal reinforcement ratio of the boundary regions and length on the OOP response of walls are evaluated. A clear trend was observed regarding the influence of these parameters on the initiation of OOP displacement, based on which simple equations are proposed for prediction of OOP instability in rectangular walls.

Authors: Al-adwan Mamdouh Hassan Mane
Published: August 2021

Using the remote communication technology in investigation and trial procedures is based on linking the parties of a criminal case in one geographical scope, or in several areas in the same country, or in different regional places among different countries. Therefore, it is imperative to get acquainted with the general rules in remote investigation and trial that have been introduced by criminal legislation to break the traditional general rules of litigation, and to take into account the technological development data in the field of crime detection without prejudice to the rights of the accused or other parties to the criminal case. There is no doubt that the use of audio-visual communication technology will clearly contribute to reducing the financial burdens on the parties of the case, in addition to the legality of these procedures and their impact on the criminal justice system. Consequently, most criminal legislation seeks to include new means and methods for conducting investigations and criminal trial procedures and to create effective litigation procedures in pursuit of achieving justice in its optimal form, especially as technological and technical means are constantly developing, which would necessitate to employ this tremendous development in technological data and modern technology to develop the justice sector.
Experimental Investigation of Wash Fluid Preheating on the effectiveness of online Compressor Washing in a Suction Tunnel Compressor Cascade
Authors: AGBADEDE Roupa , KAİNGA Biweri
Published: August 2021

Online compressor washing is a promising method of preventing/ recovering the effects of fouling on the compressor blades. However, proper strategies need to be implemented for online compressor washing to be effective since it is conducted when the engine is in operation. This study presents an experimental investigation of wash fluid preheating on the effectiveness of online compressor washing in a suction wind tunnel compressor cascade. Crude oil was uniformly applied on the compressor cascade blade surfaces using a roller brush, and carborundum particles were ingested into the tunnel to create accelerated fouled blades. Demineralized water was preheated to 500C using the heat coil provided in the tank. Washing of the fouled blades were conducted using single flat fan nozzle, where the preheated and non preheated demineralized water were used separately to wash the fouled blades. When fouled blades washed with preheated demineralized and the non-preheated were compared, it was observed that there was little or no difference in terms of total pressure loss coefficient and exit flow angle. However, when the fouled and washed cases were compared, there was a significant difference in total pressure loss coefficient and exit flow angle.
Thermodynamic Evaluation Of Solid Oxide Fuel Cells Converting Biogas Into Hydrogen And Electricity
Authors: NOGUEİRA NAKASHİMA Rafael , DE OLİVEİRA Silvio
Published: August 2021

Although biogas has many qualities as a source of renewable and distributed energy, most full-scale applications are large facilities due to the lack of efficient small-scale systems. In this context, solid oxide fuel cells (SOFC) have been promoted as an alternative to convert biogas into electricity and heat with high efficiency. However, few studies have considered the use of the anode exhaust gas to co-produce green hydrogen together with electricity and heat, which could increase the performance and profitability of these systems. Thus, since there is a lack of studies focusing on these systems, this research proposes a new approach to model SOFC with direct internal reforming to produce power, hydrogen and heat. The results indicate that the proposed system is capable of reaching exergy efficiencies between 57% and 69% depending on the methane content of biogas. Hydrogen separation reduces the amount of fuel that has to be burned, which leads to less destruction of exergy in multiple processes (e.g., mixers, burners and heat exchangers). However, this design change also diminishes the amount of heat delivered by the system (-82% compared with conventional cogeneration), which may negatively affect the energy integration with anaerobic digestion. In addition, major performance improvements can be achieved by optimizing the hydrogen recovery of the pressure swing adsorption and the SOFC operating temperature.

Published: August 2021

In this study, a prototype system was established for location heating application and electricity generation through utilizing two concentrated photovoltaic thermal panels (CPV/T) possessing flat surface receivers connected in series with each other. The purpose of the system is to supply the heating needs of a room in winter season and to meet the electricity requirement of the equipment used in this system. In the analysis of the installed system, different refrigerants (10% mono propylene glycol + 90% water and 0.5% Al2O3-water nanofluid) were tested at three different flow rates (0.4 m3/h, 0.5 m3/h, 0.6 m3/h). Throughout the experiments, the fan-coil air outlet temperature used to heat the room was adjusted to 35 °C with an inverter and a process control device. The results attained from the experiments carried out using different fluids throughout different months and days (April-May) have demonstrated that the thermal and electrical efficiencies of the system are found to be in good agreement with each other when evaluated in terms of the fluids utilized. The highest electrical energy recovery was found as 268 W at 0.6 m3/h flow rate for propylene glycol-water mixture and 194 W at 0.5 m3/h flow rate for nanomixture. The total thermal energy efficiency for the system using different fluids was found to be around 22%. The total thermal energy gain of the system was also calculated as 2312 W at 0.6 m3/h for the propylene glycol mixture and 2041 W at 0.5 m3/h for the nanomixture.
Bose-Einstein Condensation of Cooper-Pairs in the Conventional Superconductors
Authors: KÖBLER Ulrich
Published: August 2021

Observed crossover events between different power functions of absolute temperature occurring below about ~1 K in the temperature dependence of the heat capacity or the thermal conductivity of the conventional superconductors are identified as transitions from Maxwell-Boltzmann to Bose-Einstein (BE) statistics of the Cooper-pairs. Because of the low mass of the Cooper pairs of 2me (with me as mass of the electron) and their high density, the BE-condensation temperature, TBE, of the Cooper-pairs is about five orders of magnitude higher than for the dilute alkali atom condensates. The condensation temperature TBE turns out to be proportional to the superconducting transition temperature TSC. From the observed TBE-values it is possible to calculate the density of the Cooper pairs. Assuming that the Cooper pairs form a dense gas of bosons, the diameter of the Cooper-pair orbitals turns out to be equal to the London penetration depth. As a conclusion, due to the large orbital diamagnetism of the Cooper-pairs pairs, only one layer of Cooper-pairs, next to the inner surface of the sample, is sufficient to shield an applied external magnetic field completely.
The Influence of Whole-Body Vibration on Cardiovascular Parameters and Changes in the Perception of an External Stimulus in Postmenopausal Women

Published: August 2021

Introduction: Medical science is constantly looking for effective methods to prevent involutional changes. Whole-body vibration training is a promising form of systemic rehabilitation.

Aim: The aim of the study was to assess the effect of whole-body vibration on basic cardiovascular parameters (heart rate and blood pressure) and changes in the perception of an external stimulus in postmenopausal women with different body composition.

Material and methods: The study was pilot and involved 20 women. Before the procedure, the body composition analysis was performed using the Tanita analyser. All participants underwent a series of vibration massage treatments lasting 30 minutes. Blood pressure, heart rate and sensory threshold levels were measured before and after the vibrotherapy.

Results: Diastolic blood pressure before vs. after (median; 74.20 vs. 71.45 mmHg; p=0.047), heart rate before vs. after (median; 67.40 vs. 66.00 bpm; p<0.001). Higher water content positively correlated with a decrease in diastolic blood pressure (R=0.51; p<0.05). The older the woman was, the less the heart rate decreased (R=-0.45; p<0.05). After vibrotherapy, the sensory threshold values in the non-dominant hand decreased slightly (p=0.076). The greater the visceral fat content (R=-0.48; p<0.05) and body weight (R=-0.56; p<0.05), the smaller was the improvement in the threshold.

Conclusions: After whole-body vibration, the values of diastolic blood pressure and heart rate in the examined women were lower than those recorded before the procedure. It has been shown that the higher water content in the female body was associated with a greater reduction in diastolic blood pressure. However, the older the woman, the less was the decrease in heart rate. After the whole-body vibrotherapy, only a slight decrease in the sensory threshold was noted. However, it was found that in the studied women the greater the content of visceral fat tissue and the body weight, the smaller the change in sensory sensitivity.

Data protection and data-driven solutions are two progressing areas permeating Brazilian society. This work presents an interdisciplinary theoretical approach related to Ethics, from the ethics in computing perspective; the LGPD, from the Law studies perspective; and the Social Network Analysis in Brazil, from the Informatics perspective. This research area utilizes personal data extensively for knowledge construction, with semantic contributions, analyzing the reality; or pragmatic, building artifacts. Challenges and inseparable issues are observed, exposed, and debated in this work. We present considerations combining the three topics, personal data in the research field of social networks in Brazil respecting the LGPD and ethics precepts.

Published: September 2021

O planejamento financeiro familiar faz parte da rotina de todas as famílias. Sistemas de informação podem auxiliar neste processo com recursos que envolvam todos os membros da família. Este artigo apresenta um mapeamento sistemático da literatura, com o objetivo de identificar sistemas de informação e estratégias utilizadas no planejamento financeiro familiar. Como resultado, foi identificado 40 sistemas de informação e observado que em muitos casos não são utilizados sistemas computacionais, pois estes não compreendem as necessidades genuínas da família, como a colaboração dos membros. A área de planejamento financeiro familiar necessita de mais estudos no desenvolvimento de sistemas de informação que apoiem as relações sociais da família no planejamento financeiro.

: This review examines the use of novel US-guided nerve blocks in clinical practice. Erector spinae block is a regional anesthesia technique doing by injecting a local anesthetic among the erector spinae muscle group and transverse processes. The phrenic nerve is a branch of the cervical plexus, arising from the anterior rami of cervical nerves C3, C4, and C5. The quadratus lumborum muscle is located along the posterior abdominal wall. It originates from the transverse process of the L5 vertebral body, the iliolumbar ligament, and the iliac crest. US-guided peripheral nerve procedures have a considerable scope of use, including treating headaches and hiccups to abdominal surgical pain, cesarean sections, musculoskeletal pathologies. These nerve blocks have been an effective addition to clinical anesthesia practice. The use of peripheral nerve blocks has improved postoperative pain, lessened the use of opioids and their potential side effects, and decreased the incidence of sleep disturbance in patients. More research should be done to further delineate the potential benefits of these blocks.

: To study the effect of four interventions on lower back pain (LBP) alongside time and to identify whether changes in nutrition and doing traditional Persian remedies (massage and rubbing white Lily oil) could relieve the LBP using a short-time treatment. The population of this study consisted of 89 subjects with chronic LBP collected in traditional Persian medicine clinics. The outcomes were two indices for LBP, Oswestry disability index (ODI), and numerical rating scale (NRS), measured three times with an interval of four weeks. Age was not an effective variable in both LBP indices. Effective interventions for both indices are almost the same. For ODI, sex (= male), nutrition, massage, using White Lily oil, and time had decreasing effects on ODI, but interactions of sex with nutrition and massage had increasing effects on ODI. For NRS, sex (= female), using White Lily oil, time, and interactions of sex with massage and nutrition had decreasing effects, but nutrition, massage, and interactions of sex with White Lily oil had increasing effects on NRS.

Authors: Mohamadkhani Ashraf
Published: August 2021

Background: In the past decade, metabolites of marine microorganisms have been increasingly used for their various biological activities. An intense effort has been dedicated to assessing the therapeutic efficacy of the marine natural products and metabolites obtained from marine bacteria in cancer therapy. Fast and reliable analytical bacterial genome sequencing provides specialized bioinformatic tools to identify potential gene clusters in bacteria for obtaining secondary metabolites. Objectives: This study aimed to analyze the genome sequences of marine bacteria to recognize bioactive compounds with anti-cancer properties. Methods: Marine bacteria with the genomic sequences registered in the National Center for Biotechnology Information (NCBI) genome database were used in this study. The genome was analyzed for proteins, tRNAs, and rRNAs from GenBank entries by Feature Extract 1.2L Server. The Anti-SMASH webserver was used for the analysis of unique marine bacterial metabolites of the marine bacterial genome, available from the NCBI database. Results: A number of marine bacterial species, including Salinispora arenicola, Salinispora tropica, Crocosphaera watsonii, and Blastopirellula marina encoded metabolites belonging to the polyketide and nonribosomal peptide (NRP) families, showing anti-cancer properties. Among the marine species described, S. tropica and S. arenicola are richer in the genes encoding polyketide and NRP with potential antitumor activities. Conclusions: Marine bacteria are an excellent and exceptional source of anti-cancer compounds. In silico genome analysis of marine bacteria provided an opportunity to evaluate gene clusters for known natural products. Like this chemical engineering approaches for pharmaceutical application are useful in clinical evaluation of cancer treatment.
