Published: October 2021

Abstract
In this paper, we study an anomalous pseudo-parabolic Kirchhoff-type dynamical model aiming to reveal the control problem of the initial data on the dynamical behavior of the solution in dynamic control system. Firstly, the local existence of solution is obtained by employing the Contraction Mapping Principle. Then, we get the global existence of solution, long time behavior of global solution and blowup solution for J(u
0) ⩽ d, respectively. In particular, the lower and upper bound estimates of the blowup time are given for J(u
0)<d. Finally, we discuss the blowup of solution in finite time and also estimate an upper bound of the blowup time for high initial energy.

Performance study and critical review on energy aware routing protocols in mobile sink based WSNs
Authors: Kamble Aparna Ashok , Patil Balaji Madhavrao 
Published: October 2021

Abstract
Wireless networks involve spatially extended independent sensor nodes, and it is associated with each other’s to preserve and identify physical and environmental conditions of the particular application. The sensor nodes batteries are equipped with restricted energy for working with an energy source. Consequently, efficient energy consumption is themain important challenge in wireless networks, and it is outfitted witharestricted power storage capacity battery. Therefore, routing protocol with energy efficiency is essential in wireless sensor network (WSN) to offer data transmission and connectivity with less energy consumption. As a result, the routing scheme is the main factor for decreasing energy consumption and the network's lifetime. The energy-aware routing model is mainly devised for WSN with high network performance when transmitting data to a sink node. Hence, in this paper, the effectiveness of energy-aware routing protocols in mobile sink-based WSNs is analyzed and justified. Some energy-aware routing systems in mobile sink-based WSN techniques, such as optimizing low-energy adaptive clustering hierarchy (LEACH) clustering approach, hybrid model using fuzzy logic, and mobile sink. The fuzzy TOPSIS-based cluster head selection (CHS) technique, mobile sink-based energy-efficient CHS model, and hybrid Harris Hawk-Salp Swarm (HH-SS) optimization approach are taken for the simulation process. Additionally, the analytical study is executed using various conditions, like simulation, cluster size, nodes, mobile sink speed, and rounds. Moreover, the performance of existing methods is evaluated using various parameters, namely alive node, residual energy, delay, and packet delivery ratio (PDR).
Bibliophilia in Ottoman Aleppo: Muḥammad al-Taqawī and his Medical Library
Authors: Reier Benedikt 
Published: October 2021

Abstract
Recent research has shown that book collecting by private individuals and institutions was a widespread phenomenon in Bilād al-Shām. At least from the Ayyubid period onwards, countless volumes were produced, changed hands in the book market, and lay around in libraries. To this day, Damascus occupies a central position in our knowledge about libraries and book culture in general, while other cities and regions lag behind. In this article, the inventory of an Aleppine book collector is used to take a glimpse at the book culture of Aleppo in the first decades of the seventeenth century. Although most probably not reflecting the sum total of his library, the inventory still allows to ascertain the specific taste of its compiler, an otherwise unknown Aleppine bibliophile. The inventory also provides evidence for the early distribution of Arabic print and pushes the door open for investigating the role of local agents in the early days of attempts by Orientalists to acquire Arabic manuscripts for European libraries.

Abstract

Introduction
This study is to investigate the effect of late-onset hemorrhagic cystitis (LOHC) on progression-free survival (PFS) of patients after haploidentical peripheral blood hematopoietic stem cell transplantation (haplo-PBSCT).

Methods
This retrospective study enrolled 74 patients with hematological malignancies treated with a myeloablative conditioning regimen and haplo-PBSCT. The effect of LOHC on PFS was studied in terms of HC occurrence, grade, disease type, duration, onset time, gender, and age.

Results
There were 28 patients with LOHC, and no case was with early-onset HC. The cumulative incidence of LOHC was 37.8% (95% CI: 26.9–48.7%). The 2-year expected PFS of 74 patients and 34 AML patients was not significantly different between LOHC patients and patients without HC (P > 0.05). Among 27 ALL patients, the 2-year expected PFS of LOHC patients was 75%, significantly higher than patients without HC (54.2%) (P < 0.05). The 2-year expected PFSs of patients with mild LOHC and severe LOHC were 69.8 and 77.8%, respectively (P > 0.05). Similarly, the onset time, duration, age, and gender of LOHC patients did not show significant effects on PFS (P > 0.05).

Conclusions
After haplo-PBSCT, LOHC has a significant effect on the PFS of ALL patients. The HC grade, duration, onset time, gender, and age have no significant effect on PFS.
A novel ternary bismuthide, NaMgBi: crystal and electronic structure and electrical properties
Authors: Yamada Takahiro , Matsuo Naoki , Enoki Masanori , Yamane Hisanori 
Published: October 2021

Abstract
A new ternary sodium magnesium bismuthide, NaMgBi, has been synthesized from the constituent metals, and its crystal structure was determined by single-crystal X-ray diffraction. NaMgBi crystallizes in a tetragonal PbFCl-type structure corresponding to the space group P4/nmm, where Z = 2, a = 4.7123(4) and c = 7.8158(7) Å. The structure is composed of layers formed by edge-sharing Bi tetrahedra centered with Mg stacked in the c-axis direction, and these layers sandwich the Na atoms. First-principles computations based on density functional theory calculations have verified that the most stable atomic configuration is the one in which the Na and Mg atoms occupy the 2a and 2c sites, respectively. The electrical resistivity measured for a sintered polycrystalline sample of NaMgBi with a relative density of 70% was found to gradually decrease from 868 to 26.4 mΩ cm upon increasing the temperature from 297 to 506 K, and the Seebeck coefficient decreased from 273 to 180 μV K−1 upon increasing the temperature from 298 to 496 K. Electronic structure calculations have revealed that NaMgBi must be a semiconductor with a small band gap of ∼0.1 eV.

Published: October 2021

Passados mais de 30 anos do acidente radiológico de Goiânia com uma fonte de Césio-137, os riscos associados à radioterapia externa atualmente mudaram, são dependentes de erros sistemáticos no processo de planejamento e riscos que atingem o paciente de radioterapia.O presente estudo envolveu uma revisão bibliográfica com o intuito de atualizar as informações pertinentes ao tema a respeito da segurança e proteção radiológica para os serviços de radioterapia no país. Adotou-se como critério e inclusão os descritores: Segurança do Paciente, Radioterapia, Lesões por Radiação e Efeitos da Radiação em inglês, espanhol e em português, assim como os estudos publicações posteriores ao ano 2000. Como critério de exclusão, os estudos que não preencherem os critérios de inclusão. De forma geral o desafio para todos envolvidos no processo de radioterapia está na identificação/discussão de riscos, educação continuada, maior dependência do registro eletrônico de saúde, instrução adequada com software/avanços tecnológicos, dedicando tempo para iniciativas de segurança, minimizando distrações e melhorando a comunicação. Do ponto de vista da proteção radiológica pela norma brasileira as exposições ocupacionais e do público são bem estabelecidas. Entretanto, os novos desafios se encontram no cuidado permanente das exposições médicas (do paciente), nas sobre-exposições de doses de radiações ionizantes executadas durante as imagens de planejamento e do ponto de vista do controle de qualidade o foco é bem estabelecido no desempenho dos equipamentos e a mudança está na Garantia ou gestão da Qualidade (foco na qualidade dos cuidados ao paciente), representando que esta é uma área da radiologia médica que exige uma dedicação por uma equipe multidisciplinar.

Authors: Brito Thiago Souza Pereira de , Lira Carlos Alberto Brayner de Oliveira , Vasconcelos Wagner Eustáquio de 
Published: October 2021

It is well known that safety in the operation of nuclear power plants is a primary requirement because a failure of this system can result in serious problems to the environment. A nuclear reactor has several systems that help keep it in normal operation, within safety margins. Many of these systems operate in the control of variable quantities in the primary circuit of a reactor. However, nuclear reactors are nonlinear physical systems, and this introduces a complexity in the control strategies. Among several mechanisms in the thermal-hydraulic system of a reactor that actuate as a controller, the pressurizer is the component responsible for absorbing pressure variations that occur in the primary circuit. This work aims at the development of a PID controller (Proportional Integral Derivative) based on fuzzy logic to operate in a pressurizer of a nuclear Pressurized Water Reactor. A Fuzzy Controller was developed using the process of fuzzification, inference, and defuzzification of the variables of interest to a pressurizer, then this controller was coupled to a PID Controller building a PID Controller, but oriented by Fuzzy logic. Subsequently, the PID-Fuzzy Controller was experimentally validated in a Simulation Plant in which transients like those in a PWR were conducted. The PID parameters were analyzed and adjusted for better responses and results. The results of the validation were also compared to simple controllers (on / off).

Published: October 2021

Dating of sediments was used by physics method in this work, in the physics methods the radioactivity is present, but usually it is method based on the storage of energy of radiation in the solid, in which will be employed. In the present work, Icapara sediment dating was used Electron Paramagnetic Resonance (EPR) method, in this technique the energy absorption occurs when the frequency of the incident wave is in resonance with the energy difference made by the magnetic field between the parallel and antiparallel directions to this field with the irradiated sample that creates defects in its structure. In the state of S˜ao Paulo, in the region of Iguape on the southeast coast, it is a place called Icapara, a large sand terrace that was formed due to sea level fluctation that ocorred more than 130 thousand years ago. A sample was taken from a point about 9 meters above the current control of the sea. An age of about 38,000 ±12,000 and 46,000 ± 7,000 years were obtained (EPR) to correlate with the Quaternary period and will be presented to the data obtained.

Authors: Arthur Valter , Albano Andressa Maria Simas 
Published: October 2021

The irradiation of fresh post-harvest foods has as main interests: inhibit sprouting, increase shelf life, reduce or delay damage caused by insects and diseases. This work is a preliminary study on the use of gamma radiation in fresh peas grains (Pisum sativum L.) in order to evaluate its effects on the inhibition of sprout and its increase in shelf life. The peas were submitted to 4 treatments: 0 (control), 0.15, 0.30 and 0.45 kGy, in a 60 Co research irradiator, after irradiation stored at 8 °C, being evaluated at 1, 7, 14 and 21 days after irradiation, for the following analyzes: assessments of visual appearance, total soluble solids, titratable total acidity, ratio, fresh weight loss, coloring, texture, pH, water content and ash. By visual evaluation it was observed that the irradiation did not significantly change the shelf life of the grains. The visual appearance, coloring and pH had interference due to the natural process of grain maturation. The doses of gamma radiation did not influence the content of ash, water and texture during storage and that dose of 0.45 kGy was not sufficient to inhibit the sprouting of the peas. It is possible to conclude that, with this work, a recommendation that, for the later works, in which one wishes to define the shelf life or to inhibit sprouting pea, initiate the irradiation of its samples with values above 0.45 kGy.
INFLUENCE OF IRRADIATION ON POWDER CHARACTERISTICS AND CHITOSAN SOLUTION
Authors: Arthur Valter 
Published: October 2021

Chitosan is a biodegradable polymer composed of β- (1,4) -D-glucosamine linkages (deacetylated unit) and N- acetyl-D-glucosamine (acetylated unit). It is commercially produced by the deacetylation of chitin and in the food industries it is used as a stabilizer, thickener, in water treatment and easily processed into nanofibers, gels, nanoparticles and films. The objective of this work was to evaluate the effect of gamma irradiation on morphological, rheological and color properties of chitosan and gels. Chitosan samples were irradiated at the 5, 10 and 15 kGy doses and performed by scanning electron microscopy (SEM), color and rheology. SEM analyzes showed that the chitosan particles have a network agglomerated with irregular arrangements, and the irradiated samples presented smaller granules. It was observed that gamma radiation induces changes in the intensity of the tonality of the chitosan powder and gels, increasing the brown coloration. These changes are observed by the decreasing values of L * (luminosity) with increasing radiation dose and, consequently, an increase in the values of b * (brown tone), C * and h *, indicating a higher intensity of color. As for the rheological behavior, all the gels were characterized as Newtonian fluids and the irradiation altered their viscosity, leaving them less viscous.

Published: October 2021

The short irradiation facility of the IEA-R1 nuclear research reactor at IPEN, São Paulo, Brazil, has been used for short irradiation of samples for the purpose of determining the concentration of elements of these samples through the use of the instrumental neutron activation analysis technique. With the aim of implementing the k0-NAA method at the Neutron Activation Analysis Laboratory (LAN), the reactor parameters a and f were obtained using the bare triple method. In this method, a set of three neutron flux monitors were irradiated without Cd-cover. The efficiency curve of the gamma-ray spectrometer used was determined by measuring calibrated radioactive sources at the commonly used counting geometries. The results for the parameters a and f were respectively 0.0384±0.0016 and 35.67±0.26. This value of f shows that the neutrons in the irradiation position are well thermalized.The variation of these parameters was studied with time and the reproducibility was verified.

BACKGRAUND: Cytochrome P450 is an enzyme involved in the metabolism of phase I xenobiotics, toxins, endogenous hormones and pharmaceuticals.
AIM: Is studying the polymorphism of the CYP1A1 gene (Ile462Val, rs1048943) in the Turkic-speaking populations of the central part of the North Caucasus Region (Balkars and Karachays).
MATERIALS AND METHODS: We analyzed DNA isolated from leukocytes of peripheral venous blood of a total of 177 unrelated Balkars and Karachays (104 Balkars, 73 Karachays).
RESULTS: The ethnicity of the studied individuals was established, indicating their ancestors up to the third generation. The method of genotyping was performed by real-time PCR using competing TaqMan probes. As a result: the frequency of the 462Val variant in the sample of Balkars was 8,6% (95% CI 5,2113,33), slightly above the frequency range found in European populations. In the sample of Karachays, the frequency of the 462Val allele was 7,5% (95% CI 9,8213.08), which is the upper limit of values typical for European populations.
CONCLUSION: In the Turkic-speaking populations of the central part of the North Caucasus, the CYP1A1 462Val allele occurs with a frequency characteristic of the Near Eastern and European populations.
Comparative study of oxiport laryngoscope blade versus miller laryngoscope blade for intubation in neonates and infants during general anesthesia, a prospective randomized controlled study
Authors: Gandhi Nimit , Bhatt Swati , Goswami Anisha 
Published: October 2021

Neonates and infants are prone to oxygen desaturation during the induction of general anethesia. Pharyngeal oxygen insufflation has been shown to delay the onset and severity of desaturation during apnea. We took this comparative study with the hypothesis that Oxiport Blade delays the time of onset as well as severity of desaturation as compared to Miller Blade. Eighty neonates and infants undergoing general anesthesia with endotracheal intubation were recruited and randomly assigned into two groups:-Oxiport or Miller. (Laryngoscopy performed with Oxiport or Miller Blade respectively). Results were observed in terms of lowest SPO2 attained during Intubation with each Blade, time for 1% desaturation from baseline, desaturation rate, time for intubation and Heart rate. Data from 80 patients were available for final analysis: Oxiport(n=40)-Group O and Miller(n=40)-Group M. Mean lowest SPO2 attained during laryngoscopy in Group O was 97.77±2.81 and with Group M was 92.42±3.71 with a P-value&#60;0.001. The Rate of Saturation achieved in Group O was 0.091±0.018 sec as compared to 0.342±0.122 sec in Group M and p value was &#60;0.001. The time for 1% desaturation from baseline in Group O was 17.69±3.18 sec as compared to 10.4 ±2.09 sec in Group M with p value&#60;0.001. The time for intubation and average heart rate were comparable in both the groups. Apnoeic Laryngeal Oxygen insufflation with Oxiport Blade decreases the incidence and severity of desaturation during intubation in neonates and infants.
