Perspectivas da psicologia junguiana acerca da religião
Authors: Lemos Luiz Henrique , Bonfatti Paulo Ferreira
Published: March 2020

Observa-se que o fenômeno da religião é algo extremamente complexo e muitas áreas do conhecimento acadêmico têm se dedicado há muito tempo a tentar compreendê-lo sem, contudo, esgotá-lo. Dentre as diversas áreas, a psicologia tem se apresentado nessas tentativas de entendimento com seus diversos referenciais teóricos. Nas diversas ramificações da psicologia, a perspectiva teórica junguiana tem se mostrado com uma privilegiada interface e interessante chave de compreensão, muito produtiva em relação à religião. Todavia, essa teoria psicológica tem sido, de forma superficial e incompreendida, considerada como uma teoria psicológica unilateralmente a favor da religião – o que definitivamente não é verdade. Assim sendo, através de uma tentativa de elucidação de alguns conceitos e concepções junguianas acerca da psique, esse artigo tem como objetivo apontar não só o posicionamento epistemológico de neutralidade dessa teoria como também apresentar a importância psicológica da religião enquanto criação psicológica humana que contribui, por vezes negativa e por outras positivamente, para o processo de crescimento psicológico conhecido como individuação.
As religiões na sociedade pós-industrial: leitura sociológico-filosófico-teológica
Authors: Vicente Jose Armando
Published: March 2020

Pergunta-se: que lugar e que função podem ter as religiões no contexto pós-industrial? A pluralidade religiosa constitui um mal a ser eliminado? É uma realidade negativa, pecaminosa, contrária a vontade de Deus? Ela deve ser atribuída ao poder do demônio, sendo feita de politeísmo, de idolatria e de práticas imorais? Qual o sentido ou significado sociológico, filosófico e teológico das religiões, hoje? Embora haja muitas discordâncias quanto à determinação do lugar a ser ocupado pelas religiões, há uma aprovação por parte de muitos intérpretes: a afirmação de que as religiões são elementos imprescindíveis. Elas são espaços de articulação do sentido da vida; se revelam aptas a exercer funções na vida individual e social. A pluralidade das religiões é, portanto, um fenômeno de fato. Ao lado das grandes religiões, flutuam os novos movimentos religiosos: movimentos evangélicos; Renovação Carismática Católica; movimentos de vida comunitária; a Nova Era. Enfim, ligadas aos novos movimentos, encontram-se religiões individuais e privadas, construídas a partir dos ideais da modernidade e da ecologia. Acrescenta-se a todo este quadro religioso aquilo que Tillich chamou de as “quase-religiões”: religiões humanistas do progresso, da liberdade e da igualdade.

Managing Uncertainty in Spatio-Temporal Series
Authors: Souto Yania , Moura Ana Maria , Porto Fabio
Published: March 2020

Uncertain time series analysis has recently become an important research topic, particularly when searching for features of natural phenomena using similarity functions. Natural phenomena are often modeled as time series, such as in weather forecast, in which temperature variation is monitored through space and time. In such a context, different models for weather forecast produce variations on predictions that can be interpreted as predictions uncertainty. One important problem is to represent the variations presented in predictions along space and time. In order to address a solution to this problem, this paper defines a new type of series, here named uncertain spatio-temporal series, and proposes a computational strategy to manage uncertainty in probabilistic database. Using this new series some analytical queries can be performed, leading to the discovery of interesting observation patterns.

Authors: Maciel Felipe , Oliveira Carina , Juaçaba Neto Renato , Alencar João , Rego Paulo , Bezerra Ronaldo , Gomes Danielo , Andrade Rossana , De Souza José
Published: March 2020

In this paper, we propose a novel architecture to allow the implementation of a cyber environment composed of different High Performance Computing (HPC) infrastructures (i.e., clusters, grids and clouds). To access this cyber environment, scientific researchers do not have to become computer experts. In particular, we assume that scientific researchers provide a description of the problem as an input to the cyber environment and then get their results without being responsible for managing the computational resources. We provide a prototype of the architecture and introduce an evaluation which studies a real workload of scientific applications executions. The results show the advantages of the proposed architecture. Besides, we highlight this work provides guidelines for developing cyber environments focused on e-Science.

Neste trabalho, estudamos problemas sobre caminhos mais longos em grafos tanto do ponto de vista estrutural quanto algorítmico. A primeira parte tem como foco o estudo de problemas motivados pela seguinte questão levantada por T. Gallai em 1966: todo grafo conexo contém um vértice comum a todos os seus caminhos mais longos? Discutimos brevemente alguns resultados da literatura acerca desses problemas e apresentamos nossas contribuições. Na segunda parte, investigamos o problema de encontrar um caminho mais longo em um grafo, o qual é NP-difícil para grafos arbitrários. Uma versão completa dos resultados apresentados neste resumo pode ser encontrada em [de Rezende 2014].
Multivariate Investigation of NP-Hard Problems: Boundaries Between Parameterized Tractability and Intractability
Authors: Souza Uéverton , Protti Fábio , da Silva Maise , Rautenbach Dieter
Published: March 2020

In this thesis we present a multivariate investigation of the complexity of some NP-hard problems, i.e., we first develop a systematic complexity analysis of these problems, defining its subproblems and mapping which one belongs to each side of an “imaginary boundary” between polynomial time solvability and intractability. After that, we analyze which sets of aspects of these problems are sources of their intractability, that is, subsets of aspects for which there exists an algorithm to solve the associated problem, whose non-polynomial time complexity is purely a function of those sets. Thus, we use classical and parameterized complexity in an alternate and complementary approach, to show which subproblems of the given problems are NP-hard and latter to diagnose for which sets of parameters the problems are fixed-parameter tractable, or in FPT. This thesis exhibits a classical and parameterized complexity analysis of different groups of NP-hard problems. The addressed problems are divided into four groups of distinct nature, in the context of data structures, combinatorial games, and graph theory: (I) and/or graph solution and its variants; (II) flooding-filling games; (III) problems on P3-convexity; (IV) problems on induced matchings.

Published: March 2020

Amaç: Akciğer hidatik kistinin parankim koruyucu cerrahi yöntemleri ile tedavisinin hem çocuklarda hem de yetişkinlerde iyi bir tedavi seçeneği olduğu düşünülmektedir. Ancak bu dönemde yayınlanan, çok az sayıda pediatrik çalışma yapılmıştır. Amacımız, pediatrik hastalarda sonuçları gözden geçirmek ve parankim koruyucu yöntemlerin etkinliğini değerlendirmektir.

Yöntemler: Bu çalışmaya pulmoner hidatik kist nedeniyle 2008-2019 yılları arasında opere edilen, 16 yaş altı (ortalama yaşı 8.4± 3,4 yıl) olan 75 hasta dahil edildi.

Bulgular: Hastalardan akciğerin farklı bölgelerinde bulunan toplam 108 kist cerrahi olarak çıkarılmıştır. Hastaların ortalama kist boyutu 6,75±2,4 cm’dir. 12 (%16) hastada dev kist tespit edildi. Ameliyat sonrası bir hastada kanama, diğer bir hastada bronkoplevral fistül görüldü. 4 hastada nüks görülürken, mortalite görülmedi.

Sonuç: Çocukluk çağındaki akciğerin yapısal özeliklerinden dolayı dev hidatik kistlerin oranı erişkinlerden fazladır. Bu durum hidatik kist cerrahisinde lobektomi gibi radikal yaklaşımları akla getirse de parankim koruyucu yöntemlerinin etkili sonuçlar gösterdiğini ortaya koyduk.

Published: March 2020

The Malaysia Ministry of Health reported adolescents’ low utilization of healthcare services, although they need this service as a consequence of their involvement in risky behavior. This cross-sectional study aimed to determine adolescents’ perception on risk taking behavior and their utilization of health care services. A modified self-administered questionnaire was used to collect data from 250 secondary school students aged 13 and 14 years in one of the selected schools in Malacca, Malaysia. Data were analyzed using SPSS 20. Fastfood consumption, loitering after school, physical fighting, smoking, and non-use of helmets were the most reported risky behaviors among adolescents in Malaysia. More than half of the adolescents who knew about health care services had a positive perception on their utilization of such services. Thus, the promotion of adolescents’ health services helps increase their use of these services and consequently achieve a healthy lifestyle. Abstrak Persepsi Siswa Sekolah terhadap Perilaku Risiko dan Pemanfaatan Layanan Perawatan Kesehatan.

Temporal cascade of frontal, motor and muscle processes underlying human action-stopping
Authors: Jana Sumitash , Hannah Ricci , Muralidharan Vignesh , Aron Adam R
Published: March 2020

Action-stopping is a canonical executive function thought to involve top-down control over the motor system. Here we aimed to validate this stopping system using high temporal resolution methods in humans. We show that, following the requirement to stop, there was an increase of right frontal beta (~13 to 30 Hz) at ~120 ms, likely a proxy of right inferior frontal gyrus; then, at 140 ms, there was a broad skeletomotor suppression, likely reflecting the impact of the subthalamic nucleus on basal ganglia output; then, at ~160 ms, suppression was detected in the muscle, and, finally, the behavioral time of stopping was ~220 ms. This temporal cascade supports a physiological model of action-stopping, and partitions it into subprocesses that are isolable to different nodes and are more precise than the behavioral latency of stopping. Variation in these subprocesses, including at the single-trial level, could better explain individual differences in impulse control.

Authors: Bhatt Maneesha , Pujar Lata
Published: March 2020

A study was conducted among urban and rural Pre-University College students (16-18 years) who were randomly selected from four science coaching institutes of Dharwad taluk. A quantitative research method involving cross-sectional research design was used.  Under it, firstly, a differential research design was used to know the differences in identity development of urban and rural Dharwad PUC students by their parents education and occupation. A random sample of 10 to 15 per cent were drawn from each class summing up to a total of 156 PUC-I and 156 PUC-II students from Dharwad science coaching institutes. Rural samples comprised of those students, who had completed their school education till Class-10th in their village and had come for PUC studies in coaching institutes of Dharwad located in urban area. Differential and correlational research designs were used to know the difference and relationship between identity development of PUC students and their parents education and occupation. Dimension of identity development scale was used to assess identity development of PUC students and general information schedule was used to gather basic information about respondents. Chi-square and ANOVA were used for statistical analysis. The results of the present study revealed that, father’s education and occupation was not significantly associated with identity development of urban and rural PUC students. However, mother’s education was significantly associated and differed with identity development of urban PUC students. Mother’s occupation was also significantly associatedand differed with identity development of urban and rural PUC students. Thus, there is a need to invest more on quality education of parents which can mitigate poor identity development of PUC students.

Authors: Omoregbe F. B. , Fagade O. E.
Published: March 2020

Carbapenem-resistant Gram negative bacteria in healthcare setting is an important medical problem and a major threat. These Gram negative bacteria are rapidly spreading worldwide. Clinical bacteria isolates were obtained from clinical samples Urine, High Vaginal Swab (HVS), Wound Swab (WS), Stools, Ear Swab (ES), Endocervical Swab (ECS), Sputum and Blood, from two tertiary hospitals. Environmental samples were also collected from both hospitals using standard sampling techniques. Multiple drug resistant (MDR) patterns were determined using disc diffusion technique. Biochemical tests were used in the identification. Antibiotics sensitivity of clinical and environmental isolates was verified using disc diffusion method. Detection of carbapenemase producing bacteria was done using double disc synergy test and modified Hodge test. Data obtained were analysed using descriptive statistics. Clinical bacteria (403) obtained were distributed 271 Federal Medical Centre(FMC) and 132 Benue State University Teaching Hospital (BSUTH) out of which 299 were confirmed Gram negative, 218 (FMC) and 81 (BSUTH), respectively. Thirty-nine Gram negative bacteria were also isolated from the environmental samples. A higher percentage of carbapenemase producers (12.8%) were found in environmental isolates compared to 2.7% in clinical isolates. Any levels of resistance to carbapenems calls for the need to reduce the indiscriminate use of this group of antibiotics and monitoring both in the hospitals and environment.

Authors: Adoma Victor , Darko Maxwell Adom
Published: March 2020

The marketing and sale of alcoholic drinks have of late, witnessed an irresistible boom and alcoholic producing firms are enjoying field days. Drinking of alcohol has become a significant part in the social lives of most young people even though the abusive use of alcohol has been known as a key problem of young people in many societies. A case study design was employed in the research. This research investigates the impacts of alcohol beverage advertisement on the purchasing behaviour of students at Sunyani Technical University. A probability sampling technique was used to select the 300 respondents to participate in the research. Microsoft Excel was used to import data from the Statistical Package for Social Sciences (SPSS). The analysis from the survey data indicates that most of the male students contributed and 18-35 years age category dominated in the study. The survey data designates that students do not take in alcohol and most drink alcohol during special occasions and few take it heavily. The present study explored the impact of alcohol beverage advertisement as a predictor variable on the purchasing behaviour of students at Sunyani Technical University. This means that alcohol beverage advertisement plays a vital role in students' alcoholic purchasing behaviour. Therefore, alcohol producers and marketers should incorporate these elements in adverts intended to attract their targets. The study, therefore, recommended, Alcohol manufacturers and dealers should integrate these elements in adverts intended to attract their targets, most advertisements must be run on televisions, radio, music video, billboard and movies as it is most effective introducing products to consumers, policymakers and all stakeholders in education and health should also take into consideration when planning to introduce policies to control alcohol consumption.
Clinico-microbilogical Profile of Chronic Osteomyelitis in a Tertiary Care Hospital of North India
Authors: Bashir Humaira , Nazir Asifa
Published: March 2020

Aims: Chronic osteomyelitis is an important clinical entity in patients with bone infections and is associated with great morbidity especially in developing countries. It is a persistent disease, difficult to treat and eradicate completely. Early identification and diagnosis of osteomyelitis has led to the improved management of osteomyelitis. This study was undertaken to determine the bacteriological profile of osteomyelitis and the antibiotic resistance pattern of various isolates obtained.

Study Design: It was a prospective cross-sectional hospital based study.

Place and Duration of Study: The present study was conducted in the Department of Microbiology, Government Medical College, Srinagar, from January 2019 to December 2019.

Methodology: In all, 208 patients with chronic osteomyelitis were documented during the study period. Clinical specimens like pus, pus swabs, sequestrum of bone and synovial fluid were taken and cultured aerobically .The samples were processed using standard microbiological techniques. Identification and antimicrobial susceptibility pattern of the bacterial isolates were done using the Vitek 2 (bioMerieux, France) system.

Results: A total of 208 samples were received out of which, 91 (43.75%) were positive by culture. Out of the 91 positive samples, Staphylococcus aureus 65 (64.2%) was the most commonly isolated pathogen and 67.6% of Staphylococcus aureus were MRSA. Other important organisms isolated included Acinetobacter sp (10.98%), E. coli (6.59%), Proteus mirabilis (4.3%), Pseudomonas aeruginosa (2.1%) and Klebsiella pneumoniae (2.1%). All the isolates of Staphylococcus aureus were resistant to Penicillin. However, Vancomycin resistance was not detected in any of the patients with MRSA. All Gram negative bacilli were sensitive to Colistin.

Conclusion: The wide range of causative organisms and degree of resistance to commonly used anti- microbials supports the importance of pus culture and provides important information to guide clinician’s choice of empirical antibiotics. Appropriate selection of antibiotic would help to treat the disease successfully and limit the emergence of drug resistant strains to prevent morbidity & mortality.
Concordance between TP53 alterations in blood and tissue: impact of time interval, biopsy site, cancer type and circulating tumor DNA burden
Authors: Bieg‐Bourne Cheyennedra C. , Okamura Ryosuke , Kurzrock Razelle
Published: March 2020

We examined the impact of spatial, temporal, histologic, and quantitative factors on concordance betweenTP53alterations in tissue DNA vs in circulating tumor DNA (ctDNA). Four hundred and thirty‐three patients underwent next‐generation sequencing (NGS) in which both tissue and blood samples were evaluated.TP53was detected in 258 of 433 patients (59.6%); 215 had tissueTP53alterations (49.7%); 159, ctDNA (36.7%); and 116, both tissue and ctDNA (27.8%). Overall concordance rate between ctDNA and tissue biopsies forTP53alterations was 67.2%; positive concordance was 45.0%. Overall concordance forTP53did not vary among patients with ≤ 2 months vs > 6 months between test samples; however, positive concordance trended higher when time intervals between test samples were shorter, suggesting that the lack of difference in overall concordance may be due to the large number of negative/negative tests. There was a trend toward higher overall concordance based on biopsy site (metastatic vs primary) (P = 0.07) and significantly higher positive concordance if the tissue biopsy site was a metastatic lesion (P = 0.03). Positive concordance significantly decreased in noncolorectal cancer patients vs colorectal cancer patients (P = 0.02). Finally, higher %ctDNA was associated with higher concordance rates between blood and tissue (P < 0.001). Taken together, these data indicate that both blood and tissue DNA sequencing are necessary to evaluate the full scope ofTP53alterations, and that concordance rates may be related to multiple factors including, but not limited to, amount of ctDNA, histologic context, and site of tissue biopsy.

This article covers zinc–bromine redox flow battery (ZBB) technology, which is a redox flow battery technology that is suitable for large‐scale energy storage. Due to its nonflammability, relatively high energy density, and modular design, the ZBB is now a promising candidate for energy storage systems on multi‐kW to MW scales. This article presents a thorough description of the electrochemical principle, major components, and structural design of ZBB. The information collected from a wide range of studies is organized in a new configuration to elicit the key features of ZBB technology and the issues involved in advanced ZBB technology.

Manipulation of laser emission offers promising opportunities for the generation of new spatial dimensions and applications, particularly in nanophotonics, super‐resolution imaging, and data transfer devices. However, the ability to control laser modes and wavelength in a microcavity remains challenging. Here, a novel approach is demonstrated to control laser modes by manipulating the 3D‐optical confinement, chirality, and orientations in a Fabry−Pérot microcavity with cholesteric liquid crystal droplets. Different configurations of intracavity micro‐/nanostructures generate versatile dimensions of laser modes, while the significantly reduced laser mode volume further leads to single‐mode lasing. Theoretical analysis is carried out to support this interesting discovery. Finally, switchable lasing wavelength with various surface anchoring forces and pH interactions is demonstrated. This novel concept not only provides a simple yet highly versatile method to manipulate laser emissions, but deepens insight into how molecules interact with and modulate laser light, laying the foundation for the development of tunable photonic devices at the molecular level. Promising applications include highly selective laser devices, laser‐emission imaging, and bioinspired sensing.

Nonconductive commercial viscose yarns have been coated with a commercial conducting poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) layer providing electrical conductivity which allowed a second coating of the electroactive conducting polymer polypyrrole through electropolymerization to develop textile yarns actuators. To simplify the PEDOT coating process and at the same time make this process more suitable for application in industry, a new coating method is developed and the properties of the PEDOT‐PSS conducting layer is optimized, paying attention on its effect on the actuation performance. The effect of the concentration of an additive such as dimethylsulfoxide (DMSO) on actuation, and of PEDOT:PSS layers, is investigated. Results show that on improving this conducting layer, better performance than previously developed yarn‐actuators is obtained, with strains up to 0.6%. This study provides a simple and efficient fabrication method toward soft, textile‐based actuators for wearables and assistive devices with improved features.

Burn‐McKeown syndrome (BMKS) (MIM# 608572) is a rare condition caused by biallelic variants in TXNL4A. BMKS is characterized by craniofacial dysmorphism, choanal atresia, and normal intellect in affected individuals. BMKS has overlapping clinical features with Treacher Collins syndrome. Till date, 15 families have been described with BMKS. Homozygosity or compound heterozygosity of promoter deletions and null variants in TXNL4A are known to cause most cases of BMKS. We describe the first Indian family with two siblings with BMKS and promoter type 2 deletion in homozygous state.

To date, copper is the only monometallic catalyst that can electrochemically reduce CO2 into high value and energy‐dense products, such as hydrocarbons and alcohols. In recent years, great efforts have been directed towards understanding how its nanoscale structure affects activity and selectivity for the electrochemical CO2 reduction reaction (CO2RR). Furthermore, many attempts have been made to improve these two properties. Nevertheless, to advance towards applied systems, the stability of the catalysts during electrolysis is of great significance. This aspect, however, remains less investigated and discussed across the CO2RR literature. In this Minireview, the recent progress on understanding the stability of copper‐based catalysts is summarized, along with the very few proposed degradation mechanisms. Finally, our perspective on the topic is given.

Auf der inneren Porenoberfläche des calcinierten Zeoliths SSZ‐70 wurden Nester mit drei Silanolgruppen gefunden. 2D‐1H‐Doppel‐/Tripelquanten‐Einquanten‐Korrelations‐NMR‐Experimente erlauben eine eindeutige Identifikation dieser Silanoltriadenester. In der hydrothermal synthetisierten Probe zeigen sie auch eine enge Nachbarschaft zu den Strukturdirigenten (structure directing agents, SDAs), den N,N′‐Diisobutylimidazolium‐Kationen, wobei die Defekte zum Ladungsausgleich hier negativ geladen sind (Silanoldyade und eine geladene SiO−‐Siloxygruppe). Infolge der energetisch ungünstigen Ringspannung findet keine Kondensation der Silanolgruppen zu Dreiringen während der Calcination und Entfernung des SDA statt. Dahingegen sind Tetradenester, die durch Extraktion von Bor aus B‐SSZ‐70 an unterschiedlichen Stellen eigentlich entstehen müssten, nicht stabil, und Silanolkondensation findet statt. Untersuchungen mittels Infrarotspektroskopie von adsorbiertem Pyridin zeigen eine erhöhte Acidität der Silanoltriaden, was wichtige Auswirkungen in der Katalyse nahelegt.
Recycling of multilayer packaging using a reversible cross‐linking adhesive
Authors: Kaiser Katharina M. A.
Published: March 2020

Plastic‐based multilayer packaging has an important function on the packaging market, but is currently not recyclable as the polymer layers used are usually thermodynamically immiscible. This work therefore follows the approach to prepare separable multilayer packaging using a packaging adhesive modified with thermally unstable adducts, and proposes a corresponding recycling process. For this purpose, typical multilayer structures (polyethylene (PE)// polyethylene terephtalate (PET), PET//aluminum, and PE//aluminum) were prepared by curing furan‐/maleimide‐functionalized polyurethane (PU)‐prepolymers with a three‐functional cross‐linking agent. Adhesions of up to over 3N per 15 mm test specimen were measured or substrate failures of PET films were observed. However, heating in dimethylsulfoxide, the retro‐Diels–Alder reaction takes place and the cross‐linked adhesive turns thermoplastic and dissolves in the solvent. Thus, the laminate separates and the pure PE, PET, and aluminum foils can be recovered without any PU residue.

A new series of N‐substituted pyrazoline derivatives 6a–g, 7a–g, 8a–g, and 9a–g was synthetized by reaction of hydrazine derivatives and chalcone–thiazole hybrids bearing nitrogen mustard 5a–g. The chalcones 5a–g were obtained by Claisen–Schmidt condensation of thiazole‐2‐nitrogen mustard 3 and selected acetophenones 4a–g. These new compounds 6/7/8/9a–g were screened for their antifungal activity against Cryptococcus neoformans, with IC50 values of 3.9–7.8 µg/ml for the N‐3,5‐dichlorophenyl pyrazolines 9e–g. Interestingly, those compounds show low cytotoxic effects toward erythrocytes (RBC). In addition, N‐acetyl (6a,b) and N‐formyl pyrazolines (7a, 7b, 7c, and 7g) showed inhibitory activity against methicillin‐susceptible Staphylococcus aureus, methicillin‐resistant S. aureus, and vancomycin‐intermediate S. aureus, with the most important minimum inhibitory concentration values ranging from 31.25 to 125 µg/ml. Regarding the antiprotozoal activity, thiazolyl‐pyrazolines 9g, 8f, and 7c display high activity against Plasmodium falciparum, Leishmania (V) panamensis, and Trypanosoma cruzi, with EC50 values of 11.80, 6.46, and 4.98 μM, respectively, and with 7c being approximately 2.6‐fold more potent than benznidazole with a selectivity index of 1.61 on U‐937 human cells, showing promising potential as a novel antitrypanosomal agent.
Dynamics of spherical space debris of different sizes falling to Earth

Space debris larger than 1 cm can damage space instruments and impact Earth. The low‐Earth orbits (at heights smaller than 2,000 km) and orbits near the geostationary‐Earth orbit (at 35,786 km height) are especially endangered because most satellites orbit at these latitudes. With current technology, space debris smaller than 10 cm cannot be tracked. Smaller space debris fragments burn up and evaporate in the atmosphere, but larger ones fall to Earth's surface. For practical reasons, it would be important to know the mass, composition, shape, velocity, direction of motion, and impact time of space debris re‐entering the atmosphere and falling to Earth. Since it is very difficult to measure these physical parameters, almost nothing is known about them. To partly fill this gap, we performed computer modeling with which we studied the dynamics of spherical re‐entry particles falling to Earth due to air drag. We determined the time, velocity, and angle of impact as functions of the launch height, direction, speed, and size of spherical re‐entry particles. Our results can also be used for semispherical meteoroid particles of the interplanetary dust entering the Earth's atmosphere.

This study aimed to investigate the applicability of the Øie‐Tozer model to predict human distribution volume (Vd) in the central compartment (V1), Vd at steady state (Vdss), and Vd at beta phase (Vdβ) based on animal Vd. Twenty compounds that have a human V1/Vdss of 0.053–0.66 were selected from the literature. After intravenous administration of the compounds at 0.1 mg/kg to rats, dogs, and monkeys, plasma concentrations were determined, and pharmacokinetic parameters were obtained by one/two‐compartmental analyses. The human V1, Vdss, and Vdβ were predicted from animal Vd using the Øie‐Tozer model, and the predictability was compared with that using proportionality and simple allometry. The Øie‐Tozer model was the most reliable method for the overall prediction of Vd and applicable for accurately predicting human V1, Vdss, and Vdβ (89%, 85%, and 68% of the compounds within a 3‐fold error, respectively) when data of monkey for V1 and data of three animal species for Vdss and Vdβ were used. Additionally, the predicted human Vd with the two‐compartment model was applicable for predicting pharmacokinetic profiles/parameters in humans after intravenous administration of 18 compounds [except for valproic acid (monophasic elimination profile) and chlorpromazine (deviation: Vdss < V1)]. The prediction was more accurate than that using the predicted Vdss with the one‐compartment model (e.g., underestimation of maximum plasma concentrations: 2 vs 8 compounds within a 3‐fold error, respectively). In summary, the Øie‐Tozer model was applicable for predicting human V1, Vdss, and Vdβ, and their predicted Vd with the two‐compartment model can lead to accurate pharmacokinetic prediction of compounds that show biphasic elimination.
