Objectives

Hyperinsulinemia increases the risk factor of diabetes and infertility at a manifold. Lactobacillus plantarum has several medical significances with limited reports. Hence, this study assessed the effect of L. plantarum on sexual-reproductive functions and distribution of insulin receptors in the hypothalamic-pituitary-testicular axis of hyperinsulinemic mice.

Methods

Forty male adult mice were divided into five groups as follows: control, high-fat diet (HFD) + streptozotocin (STZ), therapeutic, co-administration group type 1 (CO-AD) and probiotics. They were either simultaneously exposed to an HFD and L. plantarum treatment for 28 days with a dose of STZ injection to induce hyperinsulinemia on day 28 or treated with L. plantarum for 14 days, and following induction of hyperinsulinemia. Mice were subjected to a sexual behavioural test and thereafter sacrificed under euthanasia condition. Blood, brain and testes were collected for biochemical and immunohistochemical assays.

Results

Treatment with L. plantarum ameliorated reproductive hormones activity disruption, sexual behavioural defects, antioxidant imbalance, insulin dysregulation and lipid metabolism dysfunction following exposure to HFD + STZ when compared to the hyperinsulinemic untreated mice.

Conclusions

Taken together, data from this study reveal that L. plantarum abrogated hyperinsulinemia-induced male sexual and reproductive deficits by modulating antioxidant status, lipid metabolism and insulin signalling in the hypothalamic-pituitary-testicular axis of mice.
Evaluation of measurement uncertainty in a static tensile test
Authors: Graba Marcin
Published: May 2021

This article presents a scheme of the procedure for assessing the measurement uncertainty of material constants determined in the static tensile test. The key analysis was preceded by a discussion of the concept of uncertainty of measurement, equated with absolute error, the concept of relative error and methods of assessment of these errors, depending on the type of mutual dependence of the analyzed quantity and the measured quantities. The next step in this article shows examples of stress–strain curves, which were used to calculate errors, as well as specific material constants. By importing the spreadsheets of the Mathcad package, which was used in the analysis, the procedure for assessing the measurement uncertainty was specified.

Published: May 2021

Objectives

Traffic accidents in pedestrians is one of the most important causes of death. Understanding the status quo and identification of effective factors are necessary for the management and planning of efficient training interventions in the prevention of traffic accidents for pedestrians. Hence, the present study aimed to determine the predictors of safe road-crossing behavior among female high school students of Shahr-e Kord.

Methods

The present research was a descriptive-analytical study which was conducted on 347 female high school students of Shahr-e Kord in the academic year 2016–2017. The participants were selected using random sampling method and the required data were collected through a standard questionnaire based on the theory of planned behavior. The obtained data were statistically analyzed using Pearson correlation test and regression analysis.

Results

The mean score of participants on the adoption of safe road-crossing behavior was equal to 57.06 ± 14.74. Among the independent variables of this study, the lowest and the highest scores were related to behavioral intention and outcome expectancy, respectively. The results of multiple regression test showed that behavioral beliefs, outcome expectancy, compliance motivation and behavioral intention are predictors of the adoption of safe road-crossing behavior. In total, these constructs were able to predict 25.8% of behavioral changes.

Conclusions

Based on the study findings, the theory of planned behavior can be considered an appropriate framework for designing training interventions in order to improve students’ road-crossing behavior.
Fixed point to fixed circle and activation function in partial metric space
Authors: Tomar Anita , Joshi Meena , Padaliya S. K.
Published: May 2021

We familiarize a notion of a fixed circle in a partial metric space, which is not necessarily the same as a circle in a Euclidean space. Next, we establish novel fixed circle theorems and verify these by illustrative examples with geometric interpretation to demonstrate the authenticity of the postulates. Also, we study the geometric properties of the set of non-unique fixed points of a discontinuous self-map in reference to fixed circle problems and responded to an open problem regarding the existence of a maximum number of points for which there exist circles.
This paper is concluded by giving an application to activation function to exhibit the feasibility of results, thereby providing a better insight into the analogous explorations.

Semiotic hybridization in Persian poetry and Iranian music
Authors: Sedaghat Amir
Published: May 2021

This article demonstrates how Iranian classical music and Persian medieval poetry, taken as separate semiotic systems, form together, in certain contexts, a single hybrid semiotic system with overlapping structural features and shared aesthetic principles. Hjelmslev’s description of connotative semiotic systems serves as a theoretical framework to show the modalities of this hybridization. This phenomenon can be observed through comparative analysis of the interdependence of poetry and music in the Persianate World from a semiotic point of view. On the one hand, the quantitative (chronemic) meter of the Persian classical versification, called‘aruz, as well as its extraordinarily heavy use of rhyme display a formal structure that evokes that of a musical phrase. On the other hand, the dependence of the structure of the Iranian musical system upon the rhythmic structure of classical poetry suggests a unique character of which few examples exist. This interdependence manifests itself particularly in the mystic (Sufi) poetry of the medieval period, specifically in the work of such renowned poets as Rumi, Sa’di Shirāzi, and Hāfez, who are among the best-known in the West. Examples of their lyric works are examined here to demonstrate occurrences of the collusion between the two semiotic systems.
miR-380-5p facilitates NRF2 and attenuates cerebral ischemia/reperfusion injury-induced neuronal cell death by directly targeting BACH1
Authors: Wang Yibiao , Xu Min
Published: May 2021

Background

This study aimed to explore the role of miR-380-5p in cerebral ischemia/reperfusion (CIR) injury-induced neuronal cell death and the potential signaling pathway involved.

Methodology

Human neuroblastoma cell line SH-SY5Y cells were used in this study. Oxygen and glucose deprivation/reperfusion (OGD/R) model was used to mimic ischemia/reperfusion injury. CCK-8 assay and flow cytometry were used to examine cell survival. Quantitative real time PCR (RT-qPCR) assay and Western blotting were used to measure the change of RNA and protein expression, respectively. TargetScan and Luciferase assay was used to confirm the target of miR-380-5p. Malondialdehyde (MDA) superoxide dismutase (SOD) and glutathione peroxidase (GSHPx) were measured using commercial kits.

Results

miR-380-5p was downregulated in SH-SY5Y cells after OGD/R. Cell viability was increased by miR-380-5p, while cell apoptosis was reduced by miR-380-5p mimics. MDA was reduced by miR-380-5p mimics, while SOD and GSHPx were increased by miR-380-5p. Results of TargetScan and luciferase assay have showed that BACH1 is the direct target of miR-380-5p. Expression of NRF2 was upregulated after OGD/R, but was not affected by miR-380-5p. mRNA expression of HO-1 and NQO1 and ARE activity were increased by miR-380-5p. Overexpression of BACH1 reversed the antioxidant and neuroprotective effects of miR-380-5p.

Conclusion

miR-380-5p inhibited cell death induced by CIR injury through target BACH1 which also facilitated the activation of NRF2, indicating the antioxidant and neuroprotective effects of miR-380-5p.
Az 1687. évi második mohácsi csata egy lehetséges emlékezetpolitikai aspektusa Wilhelm Camphausen egy munkáján keresztül
Authors:   Pécsi Tudományegyetem, Természettudományi Kar, Földtudományok Doktori Iskola, Szabó Róbert
Published: May 2021

At the Battle of Harsány Hill at 1687, the united Christian army defeated the Ottoman troops and blocked them to recapture Buda Castle. The so-called “second Battle of Mohács” had numerous symbolic contents, most of them were based on highlighting the similarities and differences between the first (1526) and second (1687) battle. However, the Battle of Harsány Hill was not only a symbolic pair of the Battle of Mohács in 1526 but also appeared as a symbol of various political and geopolitical phenomenons and events of other eras. The geopolitical roots of Wilhelm Camphausen’s depiction can be traced back to the Russo-Turkish War of 1877-1878. In my work, I aimed to decipher the message conveyed by this artwork, in the late 19th century in the light of German foreign policy. After the examination of the biographical aspects of the creative artist and the stylistic features of the work, I monitored the geographical, symbolic and memory aspects of the depiction.

Metastatic mesenteric masses of small intestinal neuroendocrine tumors (SI-NETs) are known to often cause intestinal complications. The aim of this study was to identify patients at risk to develop these complications based on routinely acquired CT scans using a standardized set of clinical criteria and radiomics. Retrospectively, CT scans of SI-NET patients with a mesenteric mass were included and systematically evaluated by five clinicians. For the radiomics approach, 1128 features were extracted from segmentations of the mesenteric mass and mesentery, after which radiomics models were created using a combination of machine learning approaches. The performances were compared to a multidisciplinary tumor board (MTB). The dataset included 68 patients (32 asymptomatic, 36 symptomatic). The clinicians had AUCs between 0.62 and 0.85 and showed poor agreement. The best radiomics model had a mean AUC of 0.77. The MTB had a sensitivity of 0.64 and specificity of 0.68. We conclude that systematic clinical evaluation of SI-NETs to predict intestinal complications had a similar performance than an expert MTB, but poor inter-observer agreement. Radiomics showed a similar performance and is objective, and thus is a promising tool to correctly identify these patients. However, further validation is needed before the transition to clinical practice.
Visiones de la instrucción femenina en España (siglos XVI y XVII): Luis de León, Juan Luis Vives y Joseph Rojo
Authors: Montalvo Mareca Sergio
Published: May 2021

El presente trabajo analiza los diferentes puntos de vista en torno a la cuestión de la instrucción y la educación femeninas en los siglos XVI y XVII en España. Para lograr esta meta, se acude al análisis de tres testimonios, dos de ellos fundamentales para los estudios sobre la materia: la Instrucción de la mujer cristiana de Juan Luis Vives y La perfecta casada de Luis de León. Además, sendos testimonios se comparan con el Espejo de ilustres y perfectas señoras de Joseph Rojo. Esta obra data, aproximadamente, de las últimas décadas del siglo XVII. Tras haber trabajado con las ideas que cada autor refleja en su texto, véase infancia, formación intelectual, importancia de la virginidad o el ejercicio de las tareas domésticas, es posible obtener como conclusión una línea de pensamiento que parte de la misoginia medieval y continúa avanzando conforme se gestan y aclimatan los cambios de los siglos posteriores. El primer elemento de esta representación es La perfecta casada, pues, aunque se escribe después de la Instrucción de la mujer cristiana, los valores que refleja presentan mayor proximidad con los planteamientos medievales. El texto más avanzado es el de Rojo, más cercano a las nuevas ideas de la Ilustración. La obra permite comprobar si los cambios estudiados generaron una verdadera evolución en el pensamiento colectivo o si, por el contrario, no lograron modificar la conducta de los habitantes de la España del Siglo de Oro.
Agential Materialism and the Feminist Paradigm. A Posthumanist Approach
Authors: Fernández-Santiago Miriam
Published: May 2021

Much has been argued within the fertile critical field of feminism in the second half of the twentieth century.  With the advantage of distance from the twenty-first century, we can now gain a certain perspective on the general context of production and reception of feminist criticism as it becomes embodied in new myths that subvert the old phallogocentric ones.  My approach intends to start a dialogue between such embodiments (mainly in the work of Cixous, Hayles, de Beauvoir, and Haraway) and Karen Barad’s agential materialism, using her critical construct of “phenomenon” as an instrument to understand the feminist paradigm in the post-human context and proposing accountable diffractive intra-action as an alternative to naturalized constructs.
Unilateral tonsillar swelling: role and urgency of tonsillectomy
Authors: Kynaston J , Drever S , Shakeel M , Supriya M , Cluney Mc
Published: May 2021

Unilateral tonsillar swelling is a fairly common presenting complaint in an Ear, Nose and Throat (ENT) department. It may or may not be associated with any other symptoms. Most of the time, the tonsil asymmetry is secondary to previous history of tonsillitis, quinsy, and tonsil stones. Other benign lesions to cause tonsil swelling may include a mucus retention cyst, lipoma, polyp or papilloma. Sometimes, it is the site of primary malignancy but in these situations, it is often associated with red flag symptoms like pain in the mouth, dysphagia, odynophagia, referred otalgia, weight loss, night sweating, haemoptysis, haematemesis, hoarseness or neck nodes. Most of the patients with suspected tonsillar malignancy have underlying risk factors like smoking and excessive alcohol intake. However, lately, the tonsil squamous cell carcinoma can be found in younger patients with no history of smoking or drinking as there is rising incidence of human papilloma virus related oropharyngeal malignancy. Sometimes, lymphoma may manifest as a tonsil enlargement. If, after detailed history and examination, there remains any doubt about the underlying cause of unilateral tonsil swelling then tonsillectomy should be considered for histological analysis. it is our practice to perform bilateral tonsillectomy in such cases. We present a case of unilateral tonsillar swelling and discuss its management.
PROBLEMATIC ASPECTS OF THE FORMATION OF THE UKRAINIAN SEGMENT OF THE CARPATHIANS

Published: May 2021

In the paper a model of the formation of the folded-covering-block structure of the Carpathians at a time interval that envelops Late-Hercynian and Alpine events is substantiated. Moreover, this concerns the Outer Carpathians, but the whole Carpathians arch was characterized without going into details, a critical estimate is expressed for application of such terms as terrains, accretion prism, suture, subduction and Transcarpathian fault. It is shown that formation of the Carpathians occurred through several stages under the influence of different-directed, manly horizontal, movements, as a result of which was destruction of early formed Hercynian continental crust, laying of geosynclinals troughs, formation and further transformation of the basement of the Flysch Carpathians, its collision with Eurasian continental edge, underling of the latter under flysh complex. After completion of these processes mainly vertical movements took place that lineally formed the structure of the Carpathians as folded-covering-block one. As a result of the last event (Pliocene-Pleistocene), a differential development of intensive fracturing occurred with the influx of hydrocarbons and filling traps formed up.
Forecast estimation of oil and gas reserves of Lower Cretaceous sediments in Karkinit-Northern Crimean deep (by gas-hydrogeochemical indicators)
Authors: Kolodiy Ivanna , Medvid Halyna
Published: May 2021

Distribution features of formation waters in Karkinit-Northern Crimean deep were studied; the conditions of chemical composition origin of formation waters have been studied as well. The regional features for the distribution of formation waters and the conditions of their chemical composition forming of the Lower Cretaceous complex are established. The formation waters are salty or saline and commonly have low metamorphism intensity. The formation waters of the Lower Cretaceous complex are salt with often a low degree of metamorphosis. The values of the variation coefficients of five principal components (mineralization, (Na + K), chlorine (Cl), bromine (Br), and the water sampling depths) are estimated to range from 28.73 to 57.14 %, which indicates insignificant variability each of these indicators; this characteristic does not depend on the type of water and place of sampling. The seven objects of the correlation such as mineralization, chlorine, calcium, ammonium, bromine, sulfates and hydrocarbonates are closely associated with each other. The land waters are commonly of calcium chloride (Cl.Ca) or hydrocarbonate natrium (Hyd.Car.Na) type, whereas in the water area all variety of formation waters has been recognized. Formation waters of Late Cretaceous shelf complex as well as formation waters at Tarkhankut peninsula have close relation between chemical components, low variations in the composition of macro- and microcomponents. Therefore, the formation waters of these regions could be formed in quite similar conditions. The characteristic features of the shelf formation waters are high sulfate content, despite the fact that waters complex occurs at great depths. At the same time, a decrease in the metamorphism intensity is observed as well as an increase in the Cl/Br ratio up to 1000 or more, caused by low bromine content. It is apparent that such characteristic can be the result of extrusion of water at the late stages of clay rocks dehydration. Paleoinfiltration processes in Lower Cretaceous complex may be considered as an alternative explanation. High gas saturation in the waters of the folded basin bed has been recognized at Golytsyno area and at the Tarkhankut peninsula (Melova, Oktyabrska, Berezivska and Western Oktyabrska areas). This allows us to predict the prospects of the Lower Cretaceous sediments of the Karkinit-Northern Crimean deep.

Effect of selenium enriched wheat substrate on the nutritional and antioxidant properties of Pleurotus spp.
Authors: Sravani A. , Sharma S. , Kalia A.
Published: May 2021

The study demonstrated that cultivation of Pleurotus ostreatus var. florida, Pleurotus eryngii, Pleurotus cornucopiae and Pleurotus djamor on selenium enriched substrate did not significantly affect biological efficiency (%), but total soluble protein content, total phenolic content, flavonoid content and free radical scavenging activity (%) were found to be significantly improved in Se enriched fruit bodies as compared to the control. Elemental analysis of the Se biofortified Pleurotus mushrooms through SEM-EDS showed signals characteristic for selenium on surface of P. ostreatus. var. florida and P. djamor confirming that selenium was incorporated into the cell wall of these fruiting bodies. The Se content was found to be 22.34 μg g−1 dw in Se enriched wheat straw and 0.059 μg g−1 dw in respective non-enriched wheat straw. Se contents of Se-enriched fruit bodies were found to be higher compared to non-enriched Pleurotus spp. FT-IR spectra of proteins from Pleurotus spp. indicated an increase in the flexibility, unfolding, hydrophilicity of the proteins upon Se supplementation.
From the Exhumation of Bodies to Historical Knowledge
Authors: Muñoz-Encinar Laura
Published: May 2021

Recent research into the Spanish Civil War (1936–1939) and the first years of the Francoist dictatorship (1939–1975) estimates that approximately 200,000 people were executed in Spain during this period, either extrajudicially or after popular tribunals or court martials. The bodies of the victims were for the most part buried in mass graves, thrown into riverbeds or disposed of in mines or caves. In this paper, I discuss how forensic examination of the mass graves can yield new evidence about political repression and shed new light on documentary and oral sources. I employ a multidisciplinary approach that combines archaeology and forensic anthropology to reconstruct the facts around the killings and produce new historical knowledge about the traumatic past of contemporary Spanish society.

Published: May 2021

Background.Rib osteomyelitis is extremely rare in childhood. This localization of purulent focus represents only 1% of all osteomyelitis cases. The typical manifestations of ribs osteomyelitis are fever, chest or back pain. However, these clinical signs are not always present, and the disease can manifest in other way.

Clinical Case Description. Mother with 14 years old child K. have applied to the regional children's hospital admission department. The child had complains of right upper quadrant abdominal pain and in right part of the chest, difficulty in breathing. The disease began 2 days before admission with fatigue, weakness, and pyretic fever (39 °C). Complaints remained over time. The patient was hospitalized with the diagnosis: “Chest impact injury with severe pain syndrome? Right lung contusion?". The ultrasound examination of pleural cavities and the right anterior chest surface has revealed osteomyelitic phlegmon in VII intercostal space on the 3rd day of hospitalization. It was lanced and drained under general anesthesia, about 7 ml of liquid pus were obtained. The child received treatment according to clinical guidelines for the management of patients with such nosology. The final diagnosis was: «Acute hematogenous osteomyelitis of the VII rib, local form. Osteomyelitic phlegmon of VII intercostal space. Right pneumonitis. Bilateral mild hydrothorax». The boy was discharged on the 10th day since surgery in satisfactory condition.

Conclusion.The described clinical case is interesting for pediatric surgeons, traumatologists, infectious disease specialist. Particular attention should be paid to the clinical features of the disease and anamnestic information in such unclear clinical cases. It will allow to exclude traumatic injuries and assume the local inflammatory process.

Innovation and Agency: To What Extent Did Cultural Appropriation Affect the Development of Jewellery in Britain During the 1st to 2nd Centuries AD?
Authors: Webster Elizabeth
Published: May 2021

From the Late Iron Age (LIA) to the second century AD significant cultural and technological changes occurred within Britain, commonly associated with the new relationship formed with the Roman Empire. This paper examines the jewellery of Roman Britain in an attempt to track the changes which occurred after the Roman occupation began. This examination aims to allow us to understand the true nature of the developments and how they could have been influenced by cultural appropriation. This paper argues that the Roman occupation acted as a catalyst for change, promoting the development and innovation of techniques, styles, and designs which were already established in pre-Roman traditions. As evidence for this, the pre-existing technical and artistic interactions with places, such as Gaul and Ireland will be discussed with consideration given to the persistence and innovation of already established pre-Roman techniques. A discussion of internal trade and distribution patterns in use prior to the Roman occupation is incorporated. These existing trends will then be compared to the development patterns which emerge during the early period of Roman occupation.
Views of Social Studies Teachers on Scientific Research Methodology
Authors: BAYRAM Hüseyin
Published: May 2021

Scientific method is one means by which knowledge is created. The goal of the social studies course is to teach the methodology used by these sciences in accessing the subject information along with the information they provide from social sciences. Therefore, social studies teachers should be aware of the scientific research methodology so that they can teach according to this purpose. In this study, the focus was on how teachers consider scientific research. This study aimed to investigate social studies teachers' views on scientific research methodology. It adopted phenomenology, one of the qualitative research designs. Maximum diversity sampling and criterion sampling were used to determine the study group. Data collection consisted of two stages. In the first stage, the Views about Scientific Inquiry Questionnaire (VASI) was applied. The second stage included a semi-structured interview form prepared by the researcher. Data were analysed via the descriptive analysis technique. The codes were classified under the headings in the VASI form. Findings showed that views of social studies teachers regarding scientific research methodology were mostly wrong and inadequate. Based on the findings, recommendations were made to social studies teachers, administrators, and the officials of the Council of Higher Education (CoHE). These suggestions were as follows: Teachers need to learn about scientific research methodology, school administrators should implement programs such as in-service training for teachers on a related subject, and CoHE officials should add more content about scientific research methodology to social studies teacher training programs.
Development of Accommodation System for Faults in Thrusters of Underwater Robots
Authors: Filaretov V. F. , Zuev A. V. , Zhirabok A. N. , Protsenko A. A.
Published: May 2021

The article discusses a solution to the problem of increasing the reliability of operation of underwater robots through the use of accommodation systems that compensate for the consequences of faults that appear in the thrusters. The following types of faults were considered: 1) a fault in the rotation speed sensor of thruster, causing error in its readings; 2) overheating of the motor or short-circuiting of several turns of the winding of its armature circuit, causing a change in the value of electrical resistance; 3) the appearance of an unknown external torque effect on the engine shaft, including when winding plants on the propeller. A new method for constructing accommodation systems is proposed, which contains three stages. At the first, the detection of emerging faults is carried out using the bank of diagnostic observers. Each observer is synthesized according to a special procedure in such a way that the residual formed by it is sensitive to the appearance of various combinations of possible faults. This allows to detect each specific fault. At the second stage, the values of sensor errors and deviations of the parameters of the thruster from their nominal values are estimated by additional variable structure observers. At the third stage, additional control signals for robot’s thrusters are formed. They ensure the stabilization of dynamic properties and quality indicators of thrusters in the event of faults. The results of mathematical modeling are presented, which have confirmed the operability and high efficiency of the synthesized accommodation system.

O trabalho teve como objetivo analisar a geração de resíduos comuns do Hospital São Luiz de Cáceres do Estado de Mato Grosso, em relação à capacitação dos funcionários no local de trabalho. Trata-se de estudo de intervenção, analítico, experimental de resíduos de serviços de saúde. A realização da capacitação foi no ano de 2017, em que foram abordados cinco pontos de geração no hospital, tendo como prioridade a quantidade de resíduos gerados em cada ponto, sendo quantificados e analisados antes e após a capacitação profissional dos colaboradores. Os resultados demonstraram que os resíduos comuns gerados no local estão sendo descartados de forma incorreta, pois foram observados resíduos da classe A nas lixeiras de classe D, sendo que mesmo com a capacitação, a segregação ainda continuou sendo realizada de forma incorreta por alguns profissionais. Portanto, em função de danos financeiros e ambientais, pode-se dizer que é de suma importância que os profissionais sejam capacitados por uma pessoa qualificada. É necessária uma pessoa capacitada para se responsabilizar pelo PGRSS, SCIH e gestores, aplicando treinamento de capacitação e monitorando diretamente o manejo dos resíduos sólidos gerados no ambiente hospitalar.

Abstract

The work aimed to analyze the common residues generation of Hospital São Luiz de Cáceres of the state of Mato Grosso, in relation to the employees training in the workplace. This is an intervention, analytical and experimental study of health services residues. The training was carried out in 2017, in which five generation points were added, having as priority the amount of residues generated in each point, being quantified and advanced and after the professional employees training. The results showed that the common residues generated at the site is being disposed of incorrectly, because class A residues were observed in class D dumps, being that even with the training, the segregation still continued to be performed incorrectly by some professionals. Therefore, due to the financial and environmental damage, it can be said that it is extremely important that professionals are trained by a qualified person. A trained person is required to be responsible for the PGRSS, SCIH and managers, applying training and monitoring directly the solid residues management in the hospital environment.

Toward the Design of a Robust Bioterrorism Information System to Enhance National Security
Authors: Shokrizadeh Arani Leila
Published: May 2021

In an objective sense, security measures the absence of threats to acquired values, whereas, in a subjective sense, it refers to the absence of fear that such values will be attacked. Bioterrorism is a threat. Therefore, any threat to the country's vital goals and security components, such as population, land, and property, is a national security threat.
Establishing a robust information system is critical for detecting Bioterrorism outbreak, which is considered a threat to national security. Real-time surveillance and monitoring, fast communication, data collection, and analysis at the regional and national level are the main functions of this information system.
Early detection of bioterrorism is an important step in national security promotion. If the BIS is appropriately designed based on critical factors such as multidimensional, real-time, manage by the security agency, and have the capability for pattern recognition and detection, it will more effectively manage bioterrorism attacks by relying on its capabilities, features, and technologies. Therefore, this study investigates the features and capabilities of the Bioterrorism Information System (BIS) in national security improvement and promotion.

Aim: Since the readiness study is considered a basic step in implementing various technologies, this study was conducted to assess the readiness of Al-Zahra Ophthalmology Hospital for implementing RFID technology.
Method: This descriptive cross-sectional study was conducted in Al-Zahra Ophthalmology Hospital in Zahedan (the eastern province of Iran). Personnel of departments including emergency, management, information technology, and health information management formed the research population. A researcher-constructed questionnaire was used for data collection. The questionnaire consisted of two parts with 37 questions for assessing the hospital readiness and the barriers of using RFID technology. Data were analyzed by SPSS software version 23.
Results: The mean scores of humans, technical and organizational readiness of Al-Zahra Hospital for RFID technology were: 29, 45.14, and 33.5, respectively. In other words, technical readiness was assessed at a good level and human and organizational readiness at a moderate level. The overall readiness of Al-Zahra Hospital for RFID technology has been at a moderate level (mean score of 35.88). The mean score of barriers to using RFID technology was 37.82.
Conclusion: Based on the findings, although there are positive points about RFID technology in terms of technology acceptance, organizational and technical issues, the lack of technical manpower, radio waves equipment, and budget are among the major challenges of RFID technology implementation in Al-Zahra hospital. Therefore, allocating the budget and employing specialized human resources, and creating the necessary technical infrastructure are necessary for implementing RFID technology.

This study aimed to analyze the advantages of limestone calcination through a conventional microwave heating technique. For such a purpose, the microwave was merged by hybrid heating and a refractory ceramic internally coated with copper oxide was used with a conventional muffle furnace. It has also been analyzed the behavior of calcining limestone with different masses and variations in retention time using a muffle furnace and microwaves, both with and without using the refractory ceramic. Afterwards, the process has been modeled so as to analyze temperature versus retention time. As a result, calcination using a microwave susceptor with the refractory ceramic substance proved to be a process that takes 35% less time than conventional methods. Furthermore, there has been a reduction in 66.1% of energy expenditure. It was also observed that the new procedure offers advantages in reduced greenhouse gases emissions on account of  the release of only a single substance, ease of air treatment in industrial environments and being a more economically viable process for limestone calcination, which can be further utilized by companies belonging to such a sector.
