Wireless Temperature Measurement Validation Method for PCR Machines by Magnetic Hall-Effect Sensor
Authors: Agmal Swivano , Prakosa Jalu Ahmad , Wismogroho Agus Sukarto
Published: September 2022

The temperature validation controlled by temperature indication has a vital role in the polymerase chain reaction (PCR) test machine or thermal cycler. However, the validation process is complicated for several types of  thermal cycler. Some PCR test machines must close the lid tightly while running. It makes the probe’s cable of the temperature sensor might be pinched or break when the thermal cycler lid is closed. Opening the lid (open-air condition) makes the measurement will not accurate. To solve this problem, wireless temperature measurement and validation methods for PCR machines are developed based on magnetic field measurements. The magnetic field of the object will respond to any changes in temperature. The hall-effect sensor, which is validated by gauss meter, detects any magnetic response a certain material covers even the object. This detection yields output data processed to find the thermal cycler's appropriate temperature wireless validation method. The experiment used a Neodymium magnet as a wireless probe. The position of the Neodymium magnet pole significantly affected the relation between magnetic flux and temperature in experimental results. The reversed pole toward sensors had better linearity (R2= 0.8062) than the unreversed pole (R2= 0.7794). The annealing step commonly achieved the optimum measurement uncertainty. However, the measurement uncertainty and signal sensitivity investigation recommended employing the beneficial combination of pole magnet position to design the temperature validator based on magnetic induction for a closed lid thermal cycler (PCR machine). Overall, the experimental yields can be used to build a wireless temperature validator for a sealed PCR machine based on magnetic induction.

Authors: Fajar Mutiara , Sembiring Emenda , Handajani Marisa
Published: September 2022

Microplastics (MP) can pose a serious threat to the environment and human health because of their tiny size and ability to spread easily in water. One of the alternative treatments to remove MP from water is the rapid sand filter (RSF). The objective of this study was to analyze the effects of filter media size and loading rate on RSF performance in removing MP. The applied filter media was silica sand with effective sizes (ES) of 0.39 and 0.68 mm. The loading rates of filtration were 4; 6; 8 and 10 m3/m2-h. The MP samples were made from plastic bags and torn tires (artificial samples: 10 to 800 µm). This study showed that the MP removal percentage was up to 96.6% (MP size larger than 200 µm). The head loss increment for loading rates 4; 6; 8; 10 m3/m2-h was 0.16; 0.35; 0.34; 0.25 m (ES 0.39 m) and 0.10; 0.18; 0.18; 0.19 m (ES 0.68 m)), respectively. Meanwhile, the filtration cycle for loading rates 4; 6; 8; and 10 m3/m2-h was 5, 2, 2, and 1 days (ES 0.39 mm) and 9, 4, 3, and 3 days (ES 0.68 mm), respectively. The result of this study showed that the smaller the filter media size, the higher the head loss of the filter media bed. Furthermore, there is an increased head loss of the filter media bed when the loading rate is greater.

Published: September 2022

Startups are important for economic growth and prosperity. Since they are led by their chief executive officers (CEOs) and particularly the tech-startups deal in a dynamic environment which asks for strategic flexibility and consideration of environmental changes for superior firm performance. Considering the importance of the issue, the present study attempted to examine the role of CEO’s Machiavellian personality trait in determining firm performance. Additionally, the mediating role of strategic flexibility between the association of CEO Machiavellianism and firm performance was also tested. Moreover, the moderating role of environmental dynamism was also tested between the relationship of CEO Machiavellianism and strategic flexibility. Data were collected from CEOs of startups and subjected to PLS-SEM for data analysis. The results of the study revealed that CEO Machiavellianism is not significantly associated with firm performance, however, the relationship between Machiavellianism and firm performance was significantly mediated by strategic flexibility. Additionally, results also revealed that environmental dynamism is a significant moderator between the relationship of Machiavellianism and strategic flexibility.

Outward investment policy has been an important part of China's reform and opening-up since 1978. However, it has really made major breakthroughs since China stepped up the implementation of its “going out” strategy in the early years of the twenty-first century. Through preferential policies and measures on tax, financial and monetary reform, aid to countries, establishment of an investment support fund, and reform of administrative procedures, China is constantly expanding its investment to foreign countries, becoming one of the world’s leading countries in this field. China's investment development strategy has had a certain impact on Vietnam - China economic relations in the period 2010-2020. It has contributed to promoting Chinese investment in Vietnam, enhancing trade cooperation between the two countries; but on the other hand, it also makes the trade balance unbalanced, causing some limitations and inadequacies in the process of Chinese investment in Vietnam.

Published: September 2022

To help augment the raw material supply of the wood-based industries, the study evaluated the physical and mechanical properties (PMP) of six selected timber species in the Philippines – four fruit-bearing and two underutilized tree species. The fruit-bearing species were “nangka” (Artocarpus heterophyllus Lamk.), “santol” [Sandoricum koetjape (Burm. F.)], “durian” (Durio zibethinus Murray), and “marang” [Litsea perrottetti (Blume) F. Vill.] collected from Bislig, Surigao del Sur (Caraga Region, Mindanao), while the underutilized tree species were “antipolo” [Artocarpus blancoi (Elmer) Merr] and “batino” (Alstonia macrophylla G. Donn) collected from Batangas City and Quezon Province (Region IV, Luzon), respectively. Physical properties included relative density (RD), moisture content (MC), and shrinkage. Mechanical properties covered modulus of rupture, stress at proportional limit, and modulus of elasticity in static bending; compression parallel-and perpendicular-to-grain; shear; hardness; and toughness. Standard testing procedures (ASTM-D143) were followed. Variations on the six species’ PMP were statistically analyzed, including the effect of individual trees and height levels. Among the six species, batino exhibited the highest RD (0.60), followed by nangka (0.49), antipolo (0.47), santol (0.46), marang (0.36), and durian (0.34). The MCs of nangka, santol, durian, antipolo, batino, and marang were 111.07, 121.21, 183.7, 152.68, 85.77, and 189.97% while the volumetric shrinkages (VSs) were 6.67, 6.86, 6.96, 9.07, 12.23, and 9.39%, respectively. The RD of batino was classified moderately high; those of nangka, santol, and antipolo were moderately low; and those of marang and durian were low. There was an inverse relationship between RD and MC in the six species. The VS values of nangka, durian, and santol were classified low; those of batino were medium; and those of antipolo and marang were moderately low. Overall, the mechanical properties of batino were moderately high; those of nangka, santol, and antipolo were moderately low; and those of durian and marang were low. The mechanical properties of the six species were compared with those of the “Philippine mahogany” species traditionally used for construction.

Pineapple [Ananas comosus (L.) Merr.] has long been recognized as a source of bioactive compounds that are frequently used in health and wellness products. The benefits of pineapple, among others, include immunomodulatory and anti-inflammatory properties. This study aimed at evaluating the potential of phytochemical compounds in pineapple peel as immunomodulators and anti-inflammatory agents using an in silico approach. The phytochemical of the pineapple peel’s n-hexane extract was analyzed using GC-MS (gas chromatography–mass spectrometry). The analysis of biological activities of the phytochemicals was performed using the PASS Online webserver. Computational toxicity estimation was performed using the ProTox II webserver. The drug-likeness of the compounds was analyzed using Lipinski’s rule of five. Additionally, molecular docking of selected phytochemicals against the NLRP3 inflammasome was performed. The results suggested the presence of phytochemicals with immunomodulatory and anti- inflammatory properties in the n-hexane extract of pineapple peel. This information can be used as a starting point in the search for natural-based drugs that are effective at alleviating inflammatory symptoms, as well as in immunomodulatory aspects.

In the Philippines, there is little documentation about the population size of indigenous peoples (IPs) and more so on their health and nutrition status. This study aimed to address the gap in knowledge on the IPs’ nutrition and health status in the Philippines. Analysis of secondary data collected in the 8th National Nutrition Survey (NNS) 2013 and the 2015 Updating Survey of the Nutritional Status of Filipino Children and Other Population Groups conducted by the Department of Science and Technology–Food and Nutrition Research Institute (DOST-FNRI) was done. Face-to-face interviews, anthropometric measurements, blood extraction, urine collection, and blood pressure measurements were utilized as data collection methods. Findings illustrate that majority of the IPs belonged to the poorest and poor quintile, had low educational attainment, and were rural residents. The pervasive problem of undernutrition in the form of stunting and underweight was the most pronounced problem among children and adolescents. Overnutrition was prevalent among adults. Micronutrient deficiencies also exist in the form of anemia and iodine deficiency. There is also evidence of inadequate dietary consumption among the IPs. As evidenced by the results – compared with the non-IP individuals and households – the IP population was poorer, had a significantly higher prevalence of undernutrition and iodine deficiency, and had lower adequacy of energy and other nutrient intakes. On the other hand, the selected risk factors for non-communicable diseases such as hypertension, abdominal obesity, smoking, and alcohol consumption were more pronounced among non-IPs compared to the IPs. IPs remain a marginalized sector of society, making them highly vulnerable to the same persistent nutritional and health problems non-IPs experience. Therefore, culturally sensitive and appropriate interventions should be formulated to improve IPs’ nutrition and health status in the country.

Es war nicht nur der Schauspieler Götz George für diesen Erfolg verantwortlich. Schimanski, das war eine umwälzende Neukonzeption des "Tatort": von der Dramaturgie, über die Erzählperspektive und die Inszenierung bis zur ästhetischen Umsetzung wollte eine Gruppe junger Filmschaffender das Fernsehen besser, kinohafter machen. Die Gespräche reichen inhaltlich von der Erfindung einer neuen Serienfigur und der Besetzungsgeschichte, von Drehbuchschreiben und Inszenieren, von Motivsuche und ästhetischer Gestaltung über Diskussionen zwischen Produktion, Redaktion und Filmemacher*innen, den Umgang mit der starken Persönlichkeit des Hauptdarstellers und dem Presseecho bis zu Hypothesen über die Grunde des Erfolges beim Publikum. Genauso spannend ist aber auch die Geschichte, die die Filmemacher* innen miteinander verbindet. Ihnen allen ist gemein, dass sie Absolvent*innen der ersten Jahrgänge der Münchner Hochschule für Fernsehen und Film waren und der als '68er' bezeichneten Generation angehören. Sie haben zusammen gelernt, gearbeitet und diskutiert – wie die Zeit es erforderte.

Authors: Yin Lun
Published: September 2022

The Convention on Biological Diversity and the Nagoya Protocol have raised the issue of access and benefit sharing (ABS) and related traditional knowledge of genetic resources, particularly in the traditional knowledge conservation session. Additionally, the traditional customary law can play a significant impact. The author summarizes the concept, connotation, and nature of traditional ecological customary law, particularly that of genetic resources, and argues that it encompasses not only the common understanding of customary law for the conservation of plants and animals, but also the traditional knowledge necessary for effective classification, management, and promotion of genetic resources. Simultaneously, the author analyzes and discusses the rights recognized by traditional ecological customary law. Indigenous peoples and local communities should prioritize the establishment of their rights to genetic resources and related traditional knowledge, understand the fundamental principles of traditional ecological law and procedure, and enable them to be recognized and strengthened in international and national law, to ensure that common law and recognized rights are implemented in practice. Based on prospective progresses aforesaid, to boost the mainstreaming of traditional ecological customary law within the rule of law governing biodiversity conservation.

Solar energy schemes based on photovoltaic cells have attracted extensive interest in recent years due to their capabilities of clear and seemingly limitless generated energy. This chapter proposed a simple, cost effective and efficient system for solar photovoltaic applications. Solar energy is considered as an fastest growing renewable energy resource like wind energy for electricity generation. Solar energy is a free, clean abundant sun energy considered an inexhaustible source for electricity generation. The solar photovoltaic system is characterized by variable output power due to its operation dependency on solar irradiance and cell temperature. To maximize the energy generation potential of solar PV, a research effort is focused on solar cell manufacturing technology to increase its generation efficiency and explore advancements in power electronic devices for small and large scale deployment. The main aim is to find the unknown parameters of the nonlinear current–voltage (I-V) equations by adjusting the I-V curve at three remarkable points when the circuit is open (open circuit), when the circuit is delivering maximum power, and when it is short circuited. The data of these three studies are mentioned by all commercial PV module makers in their datasheets and with all these parameters of the adjusted I-V equation.

Invasive plants have had significant impacts on vegetation communities of Zimbabwe. A study was undertaken to determine current and potential distribution of C. edulis in Zimbabwe using DIVA GIS and MAXENT, and to determine climatic conditions under which the species thrives, together with. The species population structure and its impact on native species. Results indicate that the species has its highest occurrence frequency in Manicaland Province, followed by Matebeleland South Province. Some 13% occurrence points were recorded at an altitude less than 600 m, 21% at an altitude ranging from 600–999 m, 43% at an altitude between 1000 and 1399 m and 23% at an altitude above 1400 m. C. edulis was recorded in areas of maximum temperature range of 34°C and a minimum of 20°C. The species also occurred in regions with a mean precipitation range as low as 60–300 mm and as high as 1000–1261 mm. Further, C. edulis distribution is predicted to expand in the Eastern Highlands (Manicaland), parts of Mazowe and Bindura (Mashonaland Central Province) and parts of Matobo (Matebelaland South Province). Diameter class distributions showed an inverse J-distribution in control sites and in all three sampled sections. An irregular bell-shaped distribution was recorded for co-occurring species on C. edulis occupied sites. It was concluded that C. edulis’ regeneration potential is high and that of competing native species is unstable and has the potential to expand beyond the currently occupied sites.

Oilseed crops are major part of human diet providing energy, used for cosmetics, health supplements and other purposes. Intensive agricultural practices, overexploitation of natural resource and climate change pattern have adverse impact on soil health, thus becoming serious concern for oilseed crop production and livelihood security of farmers. Maintenance of soil health with amendments can restore, revitalize and regain the soil quality for sustainable agriculture. Soil amendments, therefore have definite advantage by improving soil health and facilitating nutrient supply to oilseed crops. Soil organic amendments such as animal manure, compost, vermicompost, biosolids/sewage sludge, biochar etc. and inorganic amendments such as gypsum, zeolite, pyrite etc. are the most commonly available amendments which can be directly applied to soil after treatments. Direct and indirect effect of soil amendments on soil chemical, physical and biological properties significantly influences soil-plant-continuum, beneficial for soil health improvement, carbon sequestration and oilseed yield improvement. Soil organic amendments could substitute nearly 25–50% of synthetic fertilizers, enhance nutrient use efficiency and influencing oilseed yield response. Soil amendments may sustain or increase oilseed productivity at reduced production and environmental cost, thus, improve soil health and water use efficiency and its quality, and mitigating climate change impact.
Stromal Cells and Extracellular Vesicles
Authors: Ude Arinzechukwu , Ogbodo Emmanuel , Okeke Kelechi
Published: September 2022

Stromal cells are stem cells in the bone marrow microenvironment that can ‘talk’ with neighbouring and distant cells within the bone marrow microenvironment. Stromal cells propagate this intercellular communication via cytokines, growth factors as well as small extracellular vesicles. The interaction between stromal cells and the haematopoietic stem cells, is crucial in the regulation of haematopoiesis. Aberration in this regulatory process will lead to the development of various diseases, including cancer. These stromal cells also play important role in the patient’s response to cancer therapy. As a result, these stromal cells may be crucial in the development and metastasis of cancer within the bone marrow microenvironment. In this chapter, we will explore the role of these stromal cells in carcinogenesis and cancer metastasis.
Novel Treatment Approach against Candida spp.: Evaluation of Antifungal and Antibiofilm In Vitro Activity of Dendritic Molecules
Authors: Gómez-Casanova Natalia , Luis Copa-Patiño José , Heredero-Bermejo Irene
Published: September 2022

Infections caused by the genus Candida are a serious threat, especially in the sanitary field. These pathogens are able to generate biofilms, which is one of the main problems because they are difficult to eradicate and are associated with a high mortality rate. These biofilms provide Candida species with increased resistance to health care drugs and disinfectants. Currently, the resistance to antifungals is increasing gradually and there are few drugs accepted for clinical use capable of combating them, and, unfortunately, these substances are sometimes toxic at the effective doses required. Therefore, finding new molecules capable of preventing the formation of biofilms or eradicating them once generated is of vital importance. In addition, it is essential to know the appropriate techniques to evaluate a new compound, guaranteeing reliable and precise data. Studies with dendritic systems of cationic nature are recently being carried out, presenting interesting and encouraging results as antimicrobials, against cells cancer cells, surface activating agents, and encapsulation of antibiotic, among others. In this chapter, we will focus on its antifungal capacity, especially its antibiofilm activity against Candida spp.

Clinical trials in radiation oncology have improved our translational science and patient care. All patients referred to departments of radiation oncology can be invited to participate in a clinical trial with multiple venues. Study endpoints can include intradepartmental endpoints to improve workflow and patient access as well as interdepartmental clinical translational trials that include the National Clinical Trials Network (NCTN) and industry. The quality of the trial is important to trial outcome and influences interpretation of the results of the study and how the results can be applied to patient care moving forward. Clinical trials in radiation oncology to date have accomplished much, however many important questions remain as patient care matures and systemic therapies become more sophisticated and associated with specific biomarkers and cellular expression products. In this chapter we review the history of clinical trials in radiation oncology and review the current status of the structure of quality assurance in clinical trials. We will review unanswered questions and areas to study in each disease area and how to design strategy for trials to address modern unmet needs in our discipline.

Authors: KOLAY Şükrü , MAVİ Esra , GÖZE Ömer Fahrettin
Published: September 2022

Actinomycosis is an infectious disease that rarely settles in the jaw. It is most commonly located in the cervicofacial, thoracic, abdominopelvic, and cerebral regions. Actinomycosis is mainly caused by Actinomyces israelii, a gram-positive facultative anaerobic bacterium. Surgical excision and antibiotic therapy are also required in the treatment approach. We present a rare case of surgical and medical treatment of Actinomycosis, which is rarely seen in the maxillary intraoral region. Actinomyces may be associated with a radicular cyst. The intraoral lesion of a 70-year-old diabetic female patient who applied to our clinic with long-term bleeding in the maxillary anterior region was surgically removed. The excised tissue was evaluated microscopically. Actinomyces associated with radicular cysts were seen. Short-term antibiotic therapy was then administered. An uneventful recovery was observed in the controls. J Microbiol Infect Dis 2022; 12(3):127-129.
