Published: November 2022

In this study, ZnO nanoparticles were prepared by a hydrothermal method with varying the reaction times, material ratios and reaction temperatures. The samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray Diffraction (XRD) and Fourier infrared spectroscopy (FTIR). It was shown that the material ratio significantly affected the structure and morphology of the synthesized ZnO nanoparticles, and then the uneven nano-octahedral structure, uniform nano-octahedral structure, nano-tubular structure, and nano-sheet structure could be obtained successively. The synthesized ZnO nanoparticles as mordant were used for the dyeing of silk fabrics with different natural dyes (tea polyphenols and hematoxylin). Moreover, they could improve the dyeing properties and fastness (wash and light) on silk fabrics to a certain extent.

Published: November 2022

Malaria remains a major public health challenge worldwide. In order to ensure a prompt and accurate malaria diagnosis, the World Health Organization recommended the confirmatory parasitological diagnosis of malaria by microscopy and malaria rapid diagnostic test (RDT) prior to antimalarial administration and treatment. This study was designed to evaluate the performance of nested polymerase chain reaction (nested PCR), light microscopy, and Plasmodium falciparum histidine-rich protein 2 rapid diagnostic test (PfHRP2 RDT) in the detection of falciparum malaria in Akure, Nigeria. A cross-sectional and hospital-based study involving 601 febrile volunteer participants was conducted in Akure, Nigeria. Approximately 2–3 mL venous blood samples were obtained from each study participant for parasitological confirmation by microscopy and PfHRP2-based malaria RDT. Thick and thin films were prepared and viewed under the light microscope for parasite detection, parasite density quantification, and species identification, respectively. Dry blood spot samples were prepared on 3MM Whatman filter paper for nested PCR. The overall prevalence of microscopy, PfHRP2 RDT, and nested PCR were 64.89% (390/601), 65.7% (395/601), and 67.39% (405/601), respectively. The estimates of sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and Youden’s j index of microscopy and RDT were 96.30, 100.00, 100.00, 92.89, 97.50, 0.963, and 95.06, 94.90, 97.47, 90.29, 95.01, and 0.899, respectively. Malaria RDT recorded higher false negativity, compared microscopy (4.94% vs. 3.70%). A near perfect agreement was reported between microscopy and nested PCR, and between PfHRP2 RDT and nested PCR with Cohen’s kappa (k) values of 0.94 and 0.88, respectively. This study revealed that PfHRP2 RDT and microscopy continues to remain sensitive and specific for falciparum malaria diagnosis in the study area.

Published: November 2022

The incidence of Japanese cedar pollinosis is increasing significantly in Japan, and a recent survey suggested that about 40% of the population will develop this disease. However, spontaneous remission is rare. The increased incident rate of Japanese cedar pollinosis is a huge issue in Japan. Allergen immunotherapy is the only fundamental treatment that modifies the natural course of allergic rhinitis and provides long-term remission that cannot be induced by general drug therapy. Sublingual immunotherapy for Japanese cedar pollinosis has been developed and has been covered by health insurance since 2014 in Japan. The indication for children was expanded in 2018. Clinical trials of sublingual immunotherapy for Japanese cedar pollinosis have demonstrated its long-term efficacy and safety. It is recommended for patients who wish to undergo fundamental treatment regardless of the severity of the practical guidelines for the management of allergic rhinitis in Japan. For sublingual immunotherapy, a long-term treatment period of 3 years or longer is recommended to obtain stable therapeutic effects. In recent years, evidence based on basic research and clinical trials has demonstrated sublingual immunotherapy-induced immunological changes and efficacy in patients; however, biomarkers that objectively predict and judge these therapeutic effects need to be established.

Published: November 2022

Viscum album L. subsp. album is a hemiparasitic plant that is recognized as a medicinal plant due to its beneficial effects, including anti-tumor activity, antioxidant, anti-inflammatory, anti-hepatotoxic, hypoglycemic, and antimicrobial properties as well as for lowering blood pressure. On the other hand, mistletoe is a biotic stressor for both deciduous trees and conifers. Our main aim was to evidence the influence of mistletoe on the content of chlorophylls, proline, total phenols, flavonoids, and antioxidant capacity of leaves from tree host trees (Malus domestica, Prunus domestica, and Populus alba) that grow on the northwest of Romania. In addition, HPLC-DAD-MS-ESI+ was used to analyze the phenolic acid and flavonoid profiles of V. album L. subsp. album leaves according to their parasitized hosts. A significant decrease in chlorophyll a level of approximately 32% was detected in poplars infested with mistletoe, followed by infested apples and plums with pigment reductions of 29.25% and 9.65%, respectively. The content of total phenols and flavonoids in the parasitized trees was higher compared to the non-parasitized ones. In the case of poplar, which presented the highest incidence of mistletoe infestation (70.37%), the content of total phenols in the leaves was two times higher compared to non-infested leaves. Based on HPLC chromatographic analysis, leaves of mistletoe growing on apple (VAM) had the highest content of phenolic acids (7.833 mg/g dw), followed by mistletoe leaves on poplar (VAO) and plum (VAP) (7.033 mg/g dw and, respectively, 5.559 mg/g dw). Among the flavonols, the predominant component was Rhamnazin glucosides in the amount of 1.025 ± 0.08 mg/g dw in VAO, followed by VAP and VAM (0.514 ± 0.04 and 0.478 ± 0.04 mg/g dw, respectively). Although our results show that mistletoe negatively influences the host trees, it is still a valuable plant that must be exploited to bring benefits to human health.

Published: November 2022

Nitrogen, phosphorus, and metals’ pollutants discharged from industrial sources eventually accumulate in lake sediment, hence increasing the difficulty of sediment treatment and disposal. In this work, the water storage ceramsite is prepared from dredged lake sediment and cyano-bacterial powder. The effects of pyrolysis temperature and cyanobacterial sediment on the porosity of ceramsite were investigated. The results showed that the pyrolysis of organic matter and the de-composition of compounds or salts can produce gas, causing a rich pore structure inside the ceramsite. When the temperature increased to 1150 °C, vitrification would collapse the pore structure inside the material. At the cyanobacterial-to-sediment ratio of 3:7, the porosity and water absorption of the material could reach 81.82% and 92.45% when the pyrolysis temperature was 500 and 1050 °C, respectively. The internal macropore structure of ceramsite improved the water absorption performance, and the mesoporous structure was responsible for its long water release time and stable water release structure. The ceramsite exhibited a superior metals’ retention effect. Under different pH and temperature conditions, the consolidation rates of Fe, Ni, Mn, Cr, and Pb in ceramsite were all more than 99%, suggesting the safety of the material in environmental applications. This study demonstrates the feasibility of the resourceful production of water storage ceramsite from lake sediment and cyanobacterial slurry, which helps to reduce the impact of solid waste on the environment. Thus, this work provides a practical basis for guiding water storage ceramsite in the construction of sponge cities.

Published: November 2022

Global greenhouse gas emissions must be reduced to achieve net-zero carbon emissions. One of the solutions for the reduction of greenhouse gas emissions is the adoption and transition from conventional vehicles to electrical vehicles (EVs). Previously, most research on EVs have been from a consumer adoption perspective, few of them are from industry transition and consumer adoption perspectives simultaneously. This also highlights the importance of SDG 12 (responsible for consumption and production). Additionally, the analyses were mostly obtained using one methodology and demonstrated only by weighting without relationships among factors. To consider the problem of adoption and transition, a systematic method should be developed. Therefore, this study intends to identify, prioritize, and display the relationship between EV adoption barriers from an automotive industry perspective using an analytic network process (ANP) and the decision-making trial and evaluation laboratory (DEMATEL) method. The research results show two contributions: First, the identified and prioritized barriers that automakers encounter in EV transition also explored the interrelationships among these barriers. Second, a model comparison of two multicriteria decision-making approaches was conducted to prioritize and identify the interlinkages among EV uptake barriers.

Published: November 2022

Cooling structures of gas turbine blades have become more complex to achieve a better cooling effect. Therefore, heat transfer analysis tools with higher accuracy and efficiency are required to verify the effectiveness of cooling designs and continuously improve the design. In this work, a data-driven method is combined with a decoupled conjugate heat transfer analysis. The analysis object is a typical air-cooled gas turbine first-stage vane with film cooling, impingement cooling, and pin-fin cooling. In addition, a conventional 3-D conjugate heat transfer simulation of the vane was executed for contrast. Results show that this method shortens the time of the heat transfer analysis process significantly and ensures accuracy. It proves that the data-driven method is effective for the evaluation of a modern gas turbine cooling design and is an improvement compared to the traditional three-dimensional heat transfer analysis method.

Published: November 2022

Rice straw is waste material from agriculture as a renewable biomass resource, but the black liquor produced by straw pulping causes serious pollution problems. The twin-screw pulping machine was designed by Solidworks software and the straw breakage model was created by the Discrete Element Method (DEM). The model of straw particles breakage process in the Twin-screw pulping machine was built by the Tavares model. The simulation results showed that the highest number of broken straw particles was achieved when the twin-screw spiral casing combination was negative-positive-negative-positive and the tooth groove angle arrangement of the negative spiral casing was 45°−30°−15°. The multi-factor simulation showed that the order of influence of each factor on the pulp yield was screw speed > straw moisture content > tooth groove angle. The Box-Behnken experiment showed that when screw speed was 550 r/min, tooth groove angle was 30°, straw moisture content was 65% and pulping yield achieved up to 92.5%. Twin-screw pulping performance verification experiments were conducted, and the results from the experimental measurements and simulation data from the model showed good agreement.
Numerical Study of Leakage and Diffusion of Underwater Oil Spill by Using Volume-of-Fluid (VOF) Technique and Remediation Strategies for Clean-Up
Authors: Liu Rengguang , Ding Shidong , Ju Guoshuai
Published: November 2022

An oil spill accident will cause serious harm to marine ecology and the environment. Rapid response and effective prevention methods are required to minimize the damage of oil spill accidents. The critical problems that marine emergency rescue teams face are when the spilled oil reaches the sea surface, the extent of the spilled oil, and how far they are from the drilling platform. However, there is no reliable model to predict the diffusion distance of spilled oil. Accurately predicting the diffusion characteristics of underwater spilled oil can provide timely and accurate information for the treatment of oil spill accidents and guide the correct implementation of emergency treatment. In this paper, the computational fluid dynamics (CFD) method was used to establish a two-phase flow model for the diffusion of a submarine oil spill. The volume-of-fluid (VOF) technique was implemented to track the interface between oil–water phases. The effects of different parameters on leakage and diffusion characteristics were investigated by adjusting spilled oil velocity, ocean current velocity, crude oil density, and crude oil viscosity. The logarithmic velocity profile was adopted for ocean currents to conform to the actual flow near the sea surface. A user-defined function (UDF) was developed and applied for CFD modeling. The focus was on analyzing the diffusion range (rising height Hp and lateral migration distance Wp) from full-field data. The results indicate that the oil spill velocity, ocean current velocity, crude oil density, and crude oil viscosity impact the viscous shear force, the oil spill’s inertia force, and the current shear effect. The formula for calculating the lateral migration distance of spilled oil under different working conditions was obtained by fitting. The results of this study can provide a scientific basis for formulating an emergency treatment plan for offshore oil spill accidents and minimizing the harm to marine ecology and the environment.

Published: November 2022

Stephaniae Tetrandrae Radix (STR) is a commonly used herb with a history of thousands of years. Accumulating evidence shows the therapeutic effect on breast cancer (BC) of STR. Here, we aimed to elucidate the active components and mechanisms of STR against BC. The active components and targets were retrieved and screened from the corresponding databases. A target protein–protein interaction (PPI) network was built and Ingenuity Pathway Analysis (IPA) used to analyze and screen key targets and pathways. Subsequently, molecular docking was performed to visualize the patterns of interactions between components and targets. Finally, the main active components of STR in treating BC were confirmed by in vitro experiments, and 34 common targets were obtained. The PPI network and IPA showed that the key targets were TP53, JUN, CASP3, and so on. Additionally, signaling pathways were enriched. Docking verified that the active components have good binding potential with the key targets, especially tetrandrine (Tet) and fangchinoline (Fang). In vitro studies confirmed that they significantly inhibited the viability of MDA-MB-231 cells and increased LDH leakage rate compared to MCF-10A cells. STR participates in many cell processes and regulate multiple targets, thereby playing an anti-breast cancer role. Tet and Fang may be the main active components.

Electrospinning can produce a new composite for coating sensitive bioactive compounds, such as anthocyanins, and the product obtained from this process presents characteristics that potentialize the application of natural pigments in foodstuffs. The present work aimed to develop a new nanofiber composite with incorporated anthocyanins from jussara pulp using polyethylene oxide through electrospinning. A decay in the percentage of anthocyanins during digestion was observed. However, the polymeric solution and composites produced maintained the antioxidant activity, showing their protective effect on bioactive compounds; furthermore, both nanofibers and polymer solution improved the thermal stability of the anthocyanins. Thus, the results obtained potentiate electrospinning composites in processed food products since the nanofibers presented superior thermal stability and antioxidant activity, even after the digestion process in vitro.
Germ-Free Robotic Friends: Loneliness during the COVID-19 Pandemic Enhanced the Willingness to Self-Disclose towards Robots
Authors: Penner Angelika , Eyssel Friederike
Published: November 2022

During the COVID-19 pandemic, many people felt lonely. Social robots may serve to alleviate such feelings of social disconnection. Prior research pointed out that lonely or socially excluded individuals were particularly willing to interact with social robots, because they tend to anthropomorphize robots. Such anthropomorphization may facilitate deeming robots suitable as social interaction partners. To extend existing research on the role of social robots for lonely people, we examined the effect of inclusionary status (i.e., inclusion vs. exclusion vs. control) on mind perception, perceived warmth, and participants’ willingness to self-disclose towards a social robot. We hypothesized that social exclusion would increase mind perception, perceived warmth, and participants’ willingness to self-disclose towards a social robot. Above and beyond, we assessed self-reported loneliness during and before the COVID-19 pandemic. Whereas inclusionary status had no effect on the dependent variables, correlational analyses revealed that the more COVID-19-induced loneliness participants experienced, the more they were willing to self-disclose towards a robot. Likewise, these individuals attributed more mind agency to the robot and reported to look forward to a conversation with the robot. Summing up, people who experience situational loneliness may be particularly prone to accept social robots as social interaction partners.
Empirical Research on the Metaverse User Experience of Digital Natives
Authors: Lee Han Jin , Gu Hyun Hee
Published: November 2022

The metaverse has been settled as a platform that is widely beloved by digital natives that are familiar with mobile devices and immersive contents. Thanks to the protocol enabling hedonic interaction, the user experience provides significant value from its communication, enabling learning experiences anytime and anywhere. However, the research topics are focused on the promotions of technology development, marketing effects, and relevant investment consensus. Surprisingly, the biggest problem was the lack of research from the perspective of the young generation, who mainly use the metaverse. This paper intends to examine the usability of digital native participants in detail and suggest how immersive contents, usage environment, and interface aspects should be designed from their point of view. As a result, the significant engagement factors and improvements, through heuristic usability evaluation considering content and user control, were discovered from individual interviews. Conversely, the elements to be supplemented in user experience were derived from information architecture and usage environment categories. In conclusion, the theoretical basis of the empirical usability evaluation on metaverse platforms and following recommendations with practical implications could gain more importance from this research.

Published: November 2022

Strong community engagement has been critical to support COVID-19 vaccine uptake in Australia and elsewhere. Community engagement builds trust, enables tailored information dissemination and shapes social norms. Engagement is particularly important in communities with greater vaccine hesitancy, lower health literacy and mistrust in authorities. Early in 2021, as a team of vaccine social scientists and clinicians, we developed a program to train and empower community, faith, industry and healthcare leaders to advocate for COVID-19 vaccines as “vaccine champions”. We partnered with the Victorian Department of Health to deliver 91 online Vaccine Champions sessions from March 2021 to June 2022. Over 80 people who received this training were supported by the Department of Health to become formal vaccine champions, independently delivering over 100 locally tailored information sessions. Our survey evaluation of 20 sessions delivered in 2022 found most participants (94%, 118/125) felt more confident to discuss safety and effectiveness of COVID-19 vaccines and find relevant information after attending a session. We also recorded >90% participant satisfaction with training content, format and presentation. Qualitative feedback from two group interviews highlighted the value of vaccine communication role plays and opportunities for discussion. In this brief report, we present an overview of the Vaccine Champions program, evaluation and next steps.

Import substitution, at present, has become one of the main directions of the technological development of our state. At the same time, import substitution is traditionally understood as the development of a complete or functional analogue of a particular product. The article shows two real examples of «indirect» import substitution, while the apparent cardinal difference in the objects of import substitution indicates (according to the author) that such an approach is fully justified and can be used not only in the field of industrial automation.

A feature of the coats of arms of the cities of Donbass is the presence of technical symbols (hammers, gears, adjustable and other wrenches, railway wheelset, pencil, anchors, copras, cowpers, etc.) and industrial landscapes that reflect the industrial specifics of the region. So it was at each of the stages of heraldic reforms and will remain a good tradition at the next stage. The coat of arms is an emblem, a distinctive sign on which objects are depicted symbolizing the owner of the coat of arms (a person, estate, clan, city, country, etc.). The creation of a coat of arms is subject to certain rules, the observance of which is mandatory. And if at the stage associated with the «Charter to Cities» approved by Catherine the Second, these rules were followed, then at the next stage in the 60-80s of the 20th century, the mass appearance of city emblems took place using a more conceptual and creative approach. You can meet the incorrect use of colors, the images are too small, which makes it difficult to read and understand the coat of arms. Such a wide appearance of coats of arms was prompted by the 100th anniversaries of the cities of Donbass, which fell at that time. The article presents three stories of the creation of the coats of arms of the cities of the Donetsk region of this particular stage. A new stage of «heraldic reform» is envisaged.
Some Factors Affecting Contribution of Cichlid Species Etroplus suratensis and Tilapia rendalli to the Gill-net Catches of a Man-made Lake in Sri Lanka
Authors: AMARASINGHE U.S. , SAMARAKOON J.I.
Published: November 2022

In the gill-net fishery of Parakrama Samudra, a man-made lake in Sri Lanka, some factors affecting species composition of the commercial landings were studied from February 1985 to February 1986, with particular reference to the cichlid species, Etroplus suratensis and Tilapia rendalli. The proportions in the catches of a water beating technique, a modified gill-net fishing method, were found to be significantly different from that of normal gill netting. These differences in the catches of E. suratensis and T. rendalli are suggested to be due to their restricted movements, associated with reproductive behavior. The increase of catches of two cichlid species with elevation of water level may have been brought about by their aggregation in recently inundated peripheral areas of the lake to feed on macrophytes. The importance of stratifying data according to fishing method and mesh size of gill net in order to determine species composition is discussed. Using this method 'or analysis, annual fish yield in Parakrama Samudra in 1985 was estimated to be about 46 kg-ha•l.

Authors: DE SILVA CELINE D. , RANASINGHE JAYANA
Published: November 2022

The toxicity of organophosphate insecticides, monocrotophos and fenthion, a carbamate insecticide BPMC and a herbicide paraquat, to post-yolk fry and 3-week-old fry of Oreochromis niloticus (L.) was studied using static conditions and continuous aeration over a period of 48 hours. LT50 and LC50 levels were determined for all toxicants. LC50 levels for monocrotophos, paraquat, fenthion and BPMC were 16.5 ppm, 5.2 ppm, 0.6 ppm and 0.12 ppm, respectively, for post-yolk fry. Older fry were able to tolerate higher concentrations, corresponding to LC50a of 45 ppm, 15 ppm, 5.2 ppm and 9 ppm for monocrotophos, paraquat, fenthion and BPMC, respectively, showing that the younger larvae were more sensitive to the toxicants and that toxicity changed with fish development. Measurements of oxygen consumption of the post-yolk fry at sublethal levels showed elevated levels to paraquat in pre-exposed fry but not under acute conditions. The sublethal levels studied showed no appreciable difference from that of the controls for the other toxicants.
Assessment of Fish Stocks Exploited by Fish Traps in the Arabian Gulf Area
Authors: LEE J.U. , AL-BAZ ALI F.
Published: November 2022

The yield isopleth diagrams of six commercially important fish species of the Arabian Gulffish trap fishery showed that the stocks of hamoor(Epinephelustauvina), hamrah (Lutjanus coccineus), sheim (Acanthopagrus latus), sheiry aethrinus nebulosus) and fersh (Plectorhynchus pictus) are exploited at an appropriate age at first capture and fishing effort, while newaiby (Otolithes argenuus) should be fished at a reduced effort level. However, the mean sizes at first maturity of all the fish species were greater than the present sizes at first capture. The multispecies analysiS for this fishery suggested that the maximum yield perrecruit will be obtained by an increase in fish trap mesh size (presently 4.0 cm in bar size) to about 6.0-7.0cm. Alternatively, the present yield per recruit can be maintained by reducing fishing effort by 20%, keeping the present mesh size.

The Covid-19 pandemic affects aspects of life such as shopping, work, to education. Teaching and learning activities that were originally carried out offline or face-to-face have been replaced by online learning. The shift from offline to online has implications for everyone involved, especially children and parents, who play a key role in the continuity of online education. Psychological effects are unavoidable when children or parents study at home. Cases of verbal abuse or verbal abuse of children by parents are increasing. The age of children who experience verbal abuse is 10-12 years old, elementary school education level. Children are trying to understand themselves and compare with their peers at that age. Children will find it difficult to adjust to their environment without parental guidance. Poor communication between parents and children is the cause of verbal abuse. The goal to be achieved is to prevent verbal abuse in children by parents with poster media through Instagram social media to convey information on how to communicate well between mother and child.
Perancangan Motion Graphic Batik Incung Kabupaten Kerinci

Many regions in Indonesia produce batik with their own characteristics, one of which is Incung batik from Kerinci Regency, precisely in the city of Sungai Penuh, Jambi Province. At first, Incung batik itself was made only by writing the characters and the colors used were generally dark red and black. However, now that it has many variants of colors and motifs, the coloring materials commonly used are materials derived from nature and synthetic materials. The motifs applied to the Incung batik today, originally came from writing (scripts) which had begun to be less well known by the people of Kerinci Regency, especially among the younger generation, the Incung script was used by the Kerinci people in ancient times to document history, write literature, spells, as well as customary law written on palm leaves, bamboo, and buffalo horns. Therefore, the designer tries to use information media in the form of animation media to attract attention as well as increase knowledge and increase public insight, especially the younger generation in Kerinci Regency so that they are more familiar with Incung batik itself.

Hero is a term for anyone who is extraordinarily meritorious to his nation. Through the figure of a hero, a symbol of struggle, defending the truth, and sacrifice, always maintained and passed down from generation to generation. The hero is also one of the important figures that must be known by all the people around him, not only remembering in his heart and thanking him, but also by imitating the attitudes and actions of the heroes. However, heroes who have many values that can be imitated are increasingly being forgotten by the younger generation. Early recognition is needed so that children can recognize and know the heroes of national independence in order to become a better generation, especially teenagers in Indonesia. The purpose of the design is to introduce the history and national independence hero figures from the Maluku Islands, namely Martha Khristina Tiahahu. The media used as a solution to the problem is by using interactive information communication, looks fun, and interesting, also is in demand by the public, especially teenagers, and can be accessed easily so that information about this problem can be spread out to the general public, especially students. Animation is a film that is the result of hand work in the form of moving images.
Perancangan Animasi Sejarah Komunitas Dayak Losarang
Authors: Hidayat Rahman , Maulina Rini
Published: November 2022

The Losarang Dayak community has existed since 1970, and is still surviving today. This community has nothing to do with the Kalimantan Dayak Tribe. The Losarang Dayak are not a traditional tribe, but a pure community founded by Paheran Takmad Diningrat in Losarang Indramayu. Having different characteristics makes this community part of the uniqueness of the Indramayu community. Some of the people of Indramayu know the existence of this community but not its history, the importance of public knowledge about the history of this community to increase mutual respect and respect and increase public insight and knowledge about the life of the Losarang Dayak Community. Previously, there had been information media in the form of books that explained the history and life values of the Losarang Dayak community by Abdurrahman AL-Muhaili. However, the book was printed in limited and academic nature. Therefore, it is necessary to design additional information regarding the history of the Losarang Dayak Community with the aim of presenting information in visual form packaged through motion graphic animation media published on the youtube platform so that it is easily accessible, and conveyed to the target audience.

A synopsis of Tridactyle Schltr. (Orchidaceae) in São Tomé and Príncipe is presented. We recognize nine species in São Tomé and Príncipe, including four new species. We describe here T. amadorii D’haijère, T. cocophila D’haijère, T. levelevis D’haijère & Stévart, and T. oboensis D’haijère & Stévart. Tridactyle armeniaca (Lindl.) Schltr., recorded by previous studies, is native to West Africa and is not found in São Tomé and Príncipe. Tridactyle exhibits an important diversification in São Tomé and Príncipe, with seven species being endemic (endemism rate > 75%). Here, new records are registered; the natural distribution ranges, habitat, ecology, and conservation status based on IUCN guidelines are detailed for all species; two names are lectotypified; and an identification key is provided.
Adaptive robust multivariable control of noninvertible memoryless systems with bounded disturbances: a generalization
Authors: Zhiteckii Leonid , Solovchuk Klavdiia
Published: November 2022

The discrete-time robust adaptive control for some classes of the uncertain multivariable memoryless (static) systems in the presence of unmeasurable bounded disturbances, whose bounds are assumed to be known is addressed. The systems where the number of the control inputs do not exceed the number of their outputs are considered. The main feature of plants to be controlled is that their gain matrices are noninvertible. The assumption that the elements of these matrices are unknown a priori but there is information about possible bounds on these elements. The problem stated and solvesd here is to design a feedback controller to be capable to cope with the noninvertibility of the gain matrices and also with the parametric uncertainty in order to reject the external disturbances and to ensure the boun­dedness of all the control and output system signals. To solve the problem above mentioned, the robust adaptive approach together with the so-called pseudoinverse or inverse model-based concept is used. Three different cases are studied. In the first case, the robust adaptive controller applicable to the uncertain plant with the square singular gain matrix is designed. The robust method employing the pseudoinverse model-based controllers whose parameters are estimated via a standard recursive adaptation procedure is proposed in the second case to deal with the unknown nonsquare gain matrices having the full rank. The approach proposed in first case is extended to the third case dealing with the control of the unknown plants the gain matrices of which represent the nonsquare matrices of not full rank. Asymptotic properties of the robustly-adaptive controllers proposed in this paper are established. Results of numerical examples given to support the theoretic study.

The objective of this article is to analyze the fundamental rights and guarantees guaranteed to women prisoners in the Brazilian prison system, highlighting the treatment that are applied to incarcerated women and highlighting the rights guaranteed to these inmates defined by gender. As well as bringing a brief comparison and criticism of the Brazilian female prison system in the face of the reality experienced daily by inmates, focusing on the gender division and the difficulties faced by this prison population that is almost invisible to the eyes of the Brazilian prison system and the criminal and procedural system. criminal prosecution of crimes. There is also a racial marking among this population, where the majority is black, generating the “mass incarceration of black women”, lacking state support and having social deficiencies, such as low education and lack of employment. Bringing a humanitarian reflection about the woman inside the prison and after it, emphasizing the biological and sanitary needs, since they are "prisoners" who menstruate, give birth and breastfeed.
