The origin of visibility: Marie-José Mondzain, André Leroi-Gourhan on the establishment of image, speech and desire
Authors: Spivakov Maxim
Published: August 2020

This article examines the elements of the philosophy of image of Marie-José Mondzain in light of the problem of relation between image, speech and desire. Although the main subject of Mondzain’s research is the iconic image and correlation between patristic concept of depiction and the modern technical regimes of its production and circulation, in a number of work she turns from the analysis of iconic image to studying the phenomenon of rock painting, analyzing interrelation and difference of the ability to production and performance of the image and speech. In these works, proceeding from the paleoanthropological theory of André Leroi-Gourhan, Mondzain analyzes the process of production and performance of rock painting as an event that defines the movement of anthropogenesis and forms human as a “desiring and speaking spectator”. The philosophy of image of Marie-José Mondzain is usually analyzed in the context of constructs of the modern French phenomenology and its “theological turn”. At the same time, a synthetic in its nature project of Mondzain sidesteps from the unambiguous affiliation with one or another philosophical tradition. This article reviews the elements of Mondzain’s philosophy of image not only in the context of paleoanthropological theory of André Leroi-Gourhan, but also a number of position of the philosophy of Jacques Derrida and Jean-François Lyotard, genetically connected with the phenomenological tradition of projects, but overcoming it in their own way. The analyzed in such context research of Marie-José Mondzain allow clarifying the meaning of invisibility, hollowness in structure of the image, attribution of the image to a speech or visible sign, and transformation of desire in the process of production and performance of the image.

Authors: Singh Rahul , Sahu Anurag , Singh Kulwant , Prasad Ravi Shankar , Pandey Nityanand
Published: August 2020

Background:

This study is aimed to find a critical volume of operated giant or massive extradural hematoma (EDH) that affects outcome significantly and analyze them with respect to their clinical, surgical, and outcome perspective.

Methods:

This retrospective study includes 253 patients operated for EDH in emergency in the Department of Neurosurgery of IMS BHU, Varanasi, India, a tertiary care center, between August 1, 2018, and November 1, 2019. Giant EDH critical volume was evaluated. Twenty-nine patients with giant EDH with clot volume ≥ 80 ml were further analyzed for clinical, surgical, and outcome predictive factors. Statistical analysis was done using Prism GraphPad ver. 8.0.0. P value was taken at 0.05.

Results:

Dichotomized group analysis with Glasgow Outcome Score (GOS) 4–5 versus GOS 1–3 for testing clot volume revealed significance difference with P < 0.001. Mean volume of GOS 1–3 came out to be 79.68 ml. Hence, we took clot volume >80 ml for further analysis. The most common age group was 20–40 (55.17%). M2 (31.03%) was the most common best motor response in operated giant EDH cases. Most of them were having severe (79.31%) head injury. Glasgow Coma Scale (GCS) at admission (P < 0.0001), pupillary changes (P = 0.0032), and best motor response (P < 0.0001) was significantly (P < 0.05) associated with outcome following surgery for giant EDH.

Conclusion:

Giant EDH with volume ≥ 80 ml is associated with poorer outcome. GCS at admission, pupillary changes, and best motor response is predictors for surgical outcome of giant EDH.
Pediatric sellar solitary fibrous tumor/ hemangiopericytoma: A rare case report and review of the literature
Authors: Ghanchi Hammad , Patchana Tye , Christian Eisha , Li Chao , Calayag Mark
Published: August 2020

Background:

Solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is a rare tumor which originates from the walls of capillaries and has historically been thought to be able to occur anywhere in the body that blood vessels are found. It is rarely found in the sellar region.

Case Description:

InS this report, we present the first case of this tumor occurring in the sellar region of a pediatric patient. This 12-year-old male presented with progressive vision loss which prompted surgical resection after a sellar lesion was discovered on imaging. The initial transsphenoidal approach resulted in subtotal resection and the patient experienced reoccurrence within 3 months. He underwent an orbitozygomatic craniotomy to achieve gross total tumor resection.

Conclusion:

We conducted a literature review of intracranial SFT/HPC in the pediatric population and found it to be an extremely rare occurrence, with <30 cases reported. The incidence of SFT/HPC occurring in the sellar region for any age group was also found to be a rare entity. Treatment recommendations for this tumor are also scarce, based on retrospective chart reviews from the adult population. The role for adjuvant radiation has mixed results.
Oversized primary intrapulmonary schwannoma: A case report and a review of the literature
Authors: Zarei Sara , Popa Alina , Moghadam Bahman , Reddy Archana , Mahmoud Ahmed
Published: August 2020

Background:

Schwannomas, also known as neurilemommas, are benign, well-circumscribed encapsulated peripheral nerve sheath tumors with rather indolent evolution. Made up of cells closely related to normal myelinating Schwann cells, these neoplasms may arise from the peripheral nervous system as well as from spinal or cranial nerves. They are mostly found in the base of the skull, neck, chest wall, posterior mediastinum, posterior spinal roots, cerebellopontine angle, retroperitoneum, and flexor surfaces of the extremities. The incidence rate of spinal schwannoma is 0.3–0.5/100,000 cases per year with an average age of 50 at diagnosis. We report a case of intrapulmonary schwannoma, adding a review of the literature.

Case Description:

A 20-year-old female patient with no significant medical history, presented with pleuritic chest pain, shortness of breath, right upper limb weakness, and numbness. A computed tomography of the chest and magnetic resonance imaging showed a 7.2 × 10.5 × 8.3 cm mass in the posterior segment of the right upper lobe, arising from the right T5-6 neural foramen; a concurrent 16 mm thick right pleural effusion was also noticed yet without evidence of nodular enhancement. The findings suggested the presence of a neurofibroma or a schwannoma. Complete resection of the tumor was achieved through posterolateral thoracotomy; the ensuing histopathological and immunohistochemical examinations confirmed the presence of a schwannoma.

Conclusion:

We believe this rare case of pulmonary invasive schwannoma illustrates the complex dynamics of this extremely rare entity; in this particular case, complete surgical excision proved to be crucial in terms of subacute management and local tumor control, at least at short and middle term. The patient is currently asymptomatic (6 months postsurgery) and remains on follow-up.

Published: August 2020

Silver nanoparticles (Ag-NPs) have attracted huge importance due to their distinctive chemical, biological and physical properties. Silver nanoparticles are widely synthesized by the chemical method, which involves the use of toxic chemicals which affects its applications. The bio-reduction method, in comparison with chemical method is more economic and eco-friendly. In the present work, the bio-based production of Ag-NPs was done by using peel extract of orange (citrus sinensis), which played a role of reducing and stabilizing agent. The biosynthesis of silver nanoparticles was optimized by one factor at a time (OFAT) with respect to peel extract concentration, silver nitrate concentration and reaction temperature. The green synthesized silver nanoparticles were characterized by UV-visible spectroscopy, Fourier transforms infrared (FT-IR) spectroscopy, Scanning electron microscopy (SEM) and X-ray diffraction (XRD). Disk diffusion method was used for the study of antibacterial activity of the bio-synthesized silver nanoparticles against the bacteria Escherichia coli and Staphylococcus aureus. The results showed that at a peel extract concentration of 6%, the temperature of 60oC and silver nitrate concentration of 0.1M, the synthesis of Ag-NPs was effective. The orange peel synthesized Ag-NPs showed effective antibacterial activity against both bacteria. However better activity was observed against bacterium Staphylococcus aureus. The results confirmed the synthesis of Ag-NPs using peel extract of citrus sinensis and its role as antibacterial agent.

Published: August 2020

Induction motors are widely used in the industrial world, home-based businesses as well as in households. Currently in the process of making tofu an induction motor is used as a motor to drive soy blending blades. At this time the use of induction motors is still manually by requiring the operator to regulate the speed of the motor. To reduce operator work, it is necessary to apply PI control as a motor speed controller so that a constant motor rotation is obtained. 1 phase induction motor can be adjusted with variable speed drive (VSD) 0.75KW 1 phase. Blending blade drive uses 0.5HP 1 phase induction motor. In the application of PI control requires some hardware namely Arduino Uno as a minimum system that gives PWM circuit input commands. And the speed sensor as a motor blending speed reader. PI tuning values obtained from the application of the Ziegerl-Nichols I method with the best Kp and Ki tuning values are 1.35 and 0.02673. This research was conducted with 3 speed variables namely 1400 rpm, 1300 and 1200 rpm. From the application of Kp and Ki tuning values, the smallest error value is 4.08% at 1400 rpm with the system response time peak (tp) 5s, rise time (tr) 3s faster, delay time (td) 3s, and settling time (ts) 9s , and a maximum overshoot of 9.8%.

Introduction: The management of the diffusion of Coronavirus disease 2019 (COVID-19) pandemic represents a massive problem for healthcare systems worldwide and Interventional Radiology (IR) is a fundamental hospital unit which must continue to provide its service. The aim of this article is to summarize the preventive measures taken in our IR unit and to report the results of these measures over a 7 weeks period. Material and Methods: Between the 25th of February, when we started to apply the recommended containing measures, and the 6th of April 2020, when all the IR staff started to undergo nasopharyngeal and oropharyngeal swabs screening, a total of 25 healthcare operators worked at our IR unit. Operators who, during this period, also worked in other hospital units such as diagnostic emergency department or other healthcare facilities, were excluded. Nasopharyngeal and oropharyngeal swabs screening and blood samples for specific SARS-CoV-2 IgG-IgM were retrospectively evaluated. Results: The overall procedures number decreased by a rate of 33% and twenty-three (16%) were performed in confirmed or strongly suspected COVID-19 patients. Two procedures were performed in non-suspected ones, who revealed positive in the following hospitalization days. Seventeen operators were included in the study. Only one of them resulted positive at the swabs, with an estimated infection rate in our IR unit of 6%. Specific SARS-CoV-2 IgG-IgM resulted negative in all the operators included. Conclusion: Our experience demonstrates that applying adequate measures to limit SARS-CoV-2 infection spread can efficiently reduce the viral transmission among IR healthcare workers.

Authors: Ahmed Mudher Abbas , Ismael Nabil T.
Published: August 2020

The horizontal expansion of cities is a problem in itself because this leads to waste in the urban land and override on agricultural land in many cases, so the percentage of residential use could be large if compared to other uses of other urban land in cities. As a result, many countries have adopted the style of vertical buildings (3 - 5) floors for low height housing reaching to higher elevations, commensurate with the value and location of the urban land within the city because these residential buildings are characterized by suitable residential densities, efficient and economical use of the urban land, as well as the integrity of services that achieve the conditions for suitable and comfortable standards for housing. The problem of this research is coming from the reliance on horizontal residential building in providing the housing units in time of essential need for housing accompanied by waste in urban land with high proportion of residential use. The research is aimed to reduce the proportion of residential use of urban land in cities, including Iraqi cities, and make them close to the percentage of residential use in the world through the relying on the vertical residential building type as developed and integrated residential complexes from planning, design and service aspects. This research supported by field study of one of the multi-family housing complexes. This residential complex consisting of residential units in the form of apartments, which represent the vertical residential building.

Family Cruciferae Juss. (Brassicaceae Burnett) of SAKHA (Yakutia) Republic
Authors: Dorofeyev V. I.
Published: August 2020

The paper offers a new revision of the species composition of the Cruciferae family in Yakutia, which is supplemented by information on the geographical distribution and taxonomic composition. In the present work, the crucifers of Yakutia are represented by 39 genera and 102 species. Among them, there are two endemic species (Boechera falcata (Turcz.) Al-Shehbaz and Smelowskia jacutica (Botsch. et Karav.) Al-Shehbaz et Warwick), and one subendemic (Isatis jacutensis (N. Busch) N. Busch). Traditionally, the genus Draba is the richest in the number of species in the territories reaching into the Arctic. At present, taking the latest processing of the genus by V. V. Petrovsky (Petrovsky, 2018) into account, it numbers 32 species, which amounts to about 1/3 of the total species richness of this family in Yakutia. The paper summarizes the nomenclature changes that have affected a number of representatives of this family in recent years, and proposes new combinations in the genus Boechera (B. pendula (L.) V. I. Dorof. Comb. Nov.) and Thellungiella (T. bursifolia (DC.) V. I. Dorof. Comb. Nov.). An analysis of the diversity of crucifers made it possible to assert that the flora of Yakutia is obviously insufficiently studied in its northwest and northeast reaches, and to suggest that the floristic zoning of Yakutia should be supplemented by outlining three supra-regions, namely the Verkhoyansk (eastern), Vilui (western) and Arctic (northern) supra-regions.

Coronavirus Covid-19 uses ACE2 (angiotensin-converting enzyme II), that is an essential regulator of heart function expressed in the heart, lung, kidney and gastrointestinal tract, but also acts a functional receptor for the spike glycoprotein (S)-it's the largest structure and makes the distinct spikes on the surface of the virus-of coronavirus to enter in the host's cells, because it's has high affinity binding with Covid-19.-The expression of ACE2 in adipose tissue (including subcutaneous and visceral) is significantly higher than that in lung, so Obesity was reported to increase vulnerability to infection.-In three types of cancer is also significantly higher the ACE2 expression that in the lung: CESC (Cervical squamous cell carcinoma and endocervical adenocarcinoma), PAAD (Pancreatic adenocarcinoma), READ (Rectum adenocarcinoma), KIRP (Kidney renal papillary cell carcinoma) and KIRC (Kidney renal clear cell carcinoma). There are many other conditions-like diabetes-that generate an high expression of ACE2 activity, like genetic predisposition, 'cause ACE2 on the X chromosome (Xp22). To be a smoker, exposed to high smog levels, to be a man or elder. Once the virus enters in host, it causes a downregulation of its binder ACE2, causing severe disorders in many districts where ACE2 could acts, especially cardiovascular diseases, kidney failure and cerebral/cognitive impairmentes.
Knowledge and Assertion in Korean
Authors: Turri John
Published: August 2020

Evidence from life science, cognitive science, and philosophy supports the hypothesis that knowledge is a central norm of the human practice of assertion. However, to date, the experimental evidence supporting this hypothesis is limited to American anglophones. If the hypothesis is correct, then such findings will not be limited to one language or culture. Instead, we should find a strong connection between knowledge and assertability across human languages and cultures. To begin testing this prediction, we conducted three experiments on Koreans in Korean. In each case, the findings replicated prior results observed in Americans and were corroborated by key findings from new replication studies on Americans using materials back-translated from Korean. These findings support the theory that there is a core, cross-culturally robust human practice of assertion and that, according to the rules of this practice, assertions should express knowledge.
Estimating the Impact of Growth Mindset on High School Mathematics Performance and Course-Taking
Authors: Kim Soobin , Schneider Barbara , Yun John
Published: August 2020

Using a randomized controlled trial in a nationally representative sample of 65 public high schools (N = 13,660), we tested the effects of a growth mindset intervention on math course- taking patterns and student achievement and explored whether school context was related to the success of the intervention. Students were randomly assigned to complete either the growth mindset intervention or a control activity during two 25-minute sessions. After participating in the growth mindset program used in the National Study of Learning Mindsets, students’ 9th- grade mathematics GPA increased by an average of 0.05 grade points on a 4.3-point scale. We found distinct patterns of treatment effects that depend on level of math preparation, course intensity, school context, and changes in students’ mindset.
Lying, Fast and Slow
Authors: Turri John
Published: August 2020

Researchers have debated whether there is a relationship between a statement’s truth-value and whether it counts as a lie. One view is that a statement being objectively false is essential to whether it counts as a lie; the opposing view is that a statement’s objective truth-value is inessential to whether it counts as a lie. We report five behavioral experiments that use a novel range of behavioral measures to address this issue. In each case, we found evidence of a relationship. A statement’s truth-value affects how quickly people judge whether it is a lie. When people consider the matter carefully and are told that they might need to justify their answer, they are more likely to categorize a statement as a lie when it is false than when it is true. When given options that inhibit perspective-taking, people tend to not categorize deceptively motivated statements as lies when they are true, even though they still categorize them as lies when they are false. Categorizing a speaker as “lying” leads people to strongly infer that the speaker’s statement is false. People are more likely to spontaneously categorize a statement as a lie when it is false than when it is true. We discuss four different interpretations of relevant findings to date. At present, the best supported interpretation might be that the ordinary lying concept is a prototype concept, with falsity being a centrally important element of the prototypical lie.
How does adopting a Growth Mindset Improve Academic Performance? Probing the Underlying Mechanisms in a Nationally- Representative Sample
Authors: Gopalan Maithreyi , Yeager David Scott
Published: August 2020

Students who are taught that intellectual abilities are not fixed but can be developed—a growth mindset of intelligence—show improvements in their academic outcomes. Specifically, the mindset treatment effects are strongest for low-achieving students and vary across school contexts, as demonstrated by several lab and field-experimental studies including the largest randomized control trial (RCT) evaluation in a nationally- representative sample of 9th graders in the US as shown by the National Study of Learning Mindsets (NSLM). Yet, the mechanisms through which a growth mindset brings about positive academic outcomes remains unclear. Past research posits a role for challenge-seeking/learning-oriented behaviors exhibited by students exposed to a growth mindset intervention. However, research illuminating this pathway from mindset to academic outcomes through student behaviors are sparse. For the first time, given the multisite RCT design and the inclusion of a rich set of mediators—especially, a mediator measured using a novel behavioral task that elicits learning-oriented behavior in the NSLM, rather than relying on just self-reported mindset measures, this research tests the complete mediational pathway and highlights a key mechanism through which growth mindset interventions may work.
PAX8 is differentially expressed in the brains of patients with psychotic disorders.
Authors: Mamoor Shahan
Published: August 2020

We used public and published microarray data (1, 2) to identify the most significant gene expression changes in the brains of patients with psychotic disorders. We identified the paired box-containing transcription factor PAX8 as differentially expressed in the dorsolateral prefrontal cortex of patients with schizophrenia and schizoaffective disorder. In neurons of the dorsolateral prefrontal cortex, PAX8 was expressed at significantly higher levels in patients with psychotic disorders.

Published: August 2020

The knowledge integrating project is part of interdisciplinary teaching, whose objective is integral training where the teacher must teach to learn. To evaluate the teacher and his methodology, Likert surveys are applied, however, his analysis by metric statistical methods can lead to errors in his interpretation. The objective was to know the perception of students regarding the knowledge integration project, for the acquisition of skills and abilities of learning to learn, and to compare Bayesian methods. Cross-sectional study, through a Likert scale survey, of students who completed the first level of instruction; the analysis using metric and ordinal Bayesian models. A significant percentage of students indicated that they had acquired aptitudes and skills of learning to learn and qualified the organization of the work method as appropriate; when comparing results between the studied methods, type I and II errors were found in the metric analysis model. The students’ perception regarding the organization and elaboration of the project with the acquisition of aptitudes and skills of learning to learn showed positive results; the use of Bayesian statistics with ordinal models is recommended for the proper interpretation of the results of questionnaires on Likert scales.

The study of abdomen-wall malformations corresponds almost exclusively to omphalocele and gastroschisis, despite their different embryonic origin, studies of the associated risk factors should be performed. The objective of this study was to compare the perinatal risk factors that in uence mortality and birth-weight in patients with omphalocele and gastroschisis, using Bayesian analogues of the t-test, ANOVA, and logistic regression. The data were obtained from the Perinatal Computer System of the Hospital Gineco-Obstétrico Isidro Ayora. From January 2009 to December 2018, 68 patients with gastroschisis and 18 with omphalocele were found, with a rate of 7.7 and 2 per 10,000 live newborns. Patients with omphalocele had a better birth weight, gastroschisis, occurs in young mothers. In both conditions mortality is associated with low weight, malformations or comorbidities in the first twelve days and respiratory and infectious complications after thirty days. The epidemiological profile of patients with abdominal wall malformations does not show signi cant differences with what was reported in other populations.
