El Tawantinsuyu y la minería lapidaria en el Noroeste argentino. Evidencias incaicas relacionadas con la explotación de turquesa en la cuenca de Ratones, Puna de Salta
Authors: Coloca Federico Ignacio
Published: April 2020

En este trabajo se analizan y discuten las evidencias arqueológicas vinculadas con la explotación lapidaria de turquesa provenientes de los sitios Cueva Inca Viejo y Abra de Minas, ubicados en la cuenca de Ratones, Puna de Salta. En recientes investigaciones se comprobó que el Cerro Inca Viejo constituye para el Noroeste argentino la primera fuente documentada con extracción prehispánica de dicho mineral. Si bien la extracción pudo haber comenzado en tiempos preincaicos, los incas habrían intensificado dicha actividad. Al respecto, se plantea que el Tawantinsuyu desarrolló en el área una organización para efectuar una minería eficiente a gran escala. Dicha organización implicó la instalación de un poblado como Abra de Minas y el establecimiento de áreas de trabajo cercanas a los pozos extractivos, como también la construcción de arquitectura ceremonial. En este sentido, se destaca la presencia de un registro vinculado con prácticas rituales que estaría relacionado con propiciaciones de festividades por parte del Imperio Inca, en donde se destacaba la hospitalidad y el agasajo, como parte de una estrategia asociada con una dominación simbólica sobre las poblaciones locales, y posiblemente sobre los grupos que fueron trasladados para trabajar en las minas.

Seperti yang diketahui olahraga Renang telah menjadi salah satu olah raga yang ikut dalam olimpiade nasional maupun internasional. Olahraga Renang juga mempunyai banyak macam tingkatan gerakan atau gaya yang dapat dipilih sesuai dengan keinginan. Oleh karena itu penulis ingin mencari informasi tentang olahraga Renang, dan membagikannya dengan pembaca. Semoga makalah ini dapet membatu pembaca untuk lebih mengenal olahraga Renang. Berenang adalah gerakan sewaktu bergerak di air, dan biasanya tanpa perlengkapan buatan. Kegiatan ini dapat dimanfaatkan untuk rekreasi dan olahraga. Berenang dipakai sewaktu bergerak dari satu tempat ke tempat lainnya di air, mencari ikan, mandi, atau melakukan olahraga air.Olahraga renang dengan gaya seperti sekarang ini kali pertama diperkenalkan di Jepang melalui kejuaraan renang yang diselenggarakan di negara itu. Pada tahun 1603, sekolah-sekolah di Jepang memasukkan olahraga renang sebagai pelajaran wajib. Oleh karena itu, tidak heran jika banyak kejuaraan renang tingkat internasional selalu didominasi oleh perenang-perenang dari Jepang. Sejalan dengan perjalanan sejarahnya, olahraga renang ini salalu mengambil jarak tempuh yang relative jauh.Di daratan Eropa, olahraga renang masuk melalui Inggris. Pada tahun 1896, renang mulai dipertandingkn di Olimpiade, saat itu masih diikuti perenang-perenang putra. Pada tahun 1912, pertandingan renang mulai diikuti oleh perenang-perenang putri. Organisasi renang dunia dikenal dengan nama Internationale de Swimming Association (ISA). Di Indonesia, induk organisasi olahraga renang adalah Persatuan Renang Seluruh Indonesia (PRSI).

Title: Suppression durations for facial expressions under breaking continuous flash suppression: effects of faces’ low-level image properties.
Authors: Webb Abigail , Hibbard Paul
Published: April 2020

Perceptual biases for fearful facial expressions are observed across many studies. According to the low-level, visual-based account of these biases, fear expressions are advantaged in some way due to their image properties, such as low spatial frequency content. Breaking continuous flash suppression (b-CFS) has explored these effects, and demonstrated similar biases for detecting fearful facial expressions. However, there is a degree of empirical disagreement regarding the range of spatial frequency content. Recent findings from a b-CFS study highlight the role of high, rather than low spatial frequency content in determining faces’ visibility. The present study contributes to ongoing discussions regarding the efficacy of b-CFS, and shows that the visibility of facial expressions varies according to how faces are normalised for physical contrast and spatially filtered. Findings show limited evidence of a bias for detecting fearful facial expressions, but importantly, they show that such biases are less likely to occur when faces are normalised for apparent, perceived contrast, compared to physical contrast. Together these findings further the current understanding of the combined effects of spatial frequency and contrast on face visibility under b-CFS, and raise important questions regarding procedures used to standardise facial stimuli.
Establishing a tumor-suppressive microenvironment with glycine and valine supplement

Published: April 2020

A tumorigenic microenvironment can give rise to neoplasm. A shift from this condition to a tumor-suppressive microenvironment is of significant benefit to susceptible individuals. The carbonyl groups of glycine and valine have long bond lengths, consequently generating potent affinities to divalent cations such as calcium. We hypothesize that the formation of insoluble and rigid calcium oxalate augmented by glycine and valine counteracts strong acids such as HCl chemically, thus reducing cancer risks. The anticancer effects of the two amino acids reported previously can be explained from a chemical and biochemical perspective. A tumor-suppressive microenvironment could be established via the modification of the proteome without genome editing at the DNA level.

We conducted a large-scale survey covering 58 countries and over 100,000 respondents between late March and early April 2020 to study beliefs and attitudes towards citizens' and governments' responses at the onset of the COVID-19 pandemic. Most respondents reported holding normative beliefs in support of COVID-19 containment measures, as well as high rates of adherence to these measures. They also believed that their government and their country's citizens were not doing enough and underestimated the degree to which others in their country supported strong behavioral and policy responses to the pandemic. Normative beliefs were strongly associated with adherence, as well as beliefs about others' and the government's response. Lockdowns were associated with greater optimism about others' and the government's response, and improvements in measures of perceived mental well-being; these effects tended to be larger for those with stronger normative beliefs. Our findings highlight how social norms can arise quickly and effectively to support cooperation at a global scale.
General Collective Intelligence and the Constraints to Group Decision-Making
Authors: Williams Andy E
Published: April 2020

This paper addresses the question of how current group decision-making systems, including collective intelligence algorithms, might be constrained in ways that prevent them from achieving general problem solving ability. And as a result of those constraints, how some collective issues that pose existential risks such as poverty, the environmental degradation that has linked to climate change, or other sustainable development goals, might not be reliably solvable with current decision-making systems. This paper then addresses the question that assuming specific categories of such existential problems are not currently solvable with any existing group decision-systems, how can decision-systems increase the general problem solving ability of groups so that such issues can reliably be solved? In particular, how might a General Collective Intelligence, defined here to be a system of group decision-making with general problem solving ability, facilitate this increase in group problem-solving ability? The paper then presents some boundary conditions that a framework for modeling general problem solving in groups suggests must be satisfied by any model of General Collective Intelligence. When generalized to apply to all group decision-making, any such constraints on group intelligence, and any such system of General Collective Intelligence capable of removing those constraints, are then applicable to any process that utilizes group problem solving, from design, to manufacturing or any other life-cycle processes of any product or service, or whether research in any field from the arts to the basic sciences. For this reason these questions are important to a wide variety of academic disciplines. And because many of the issues impacted represent existential risks to human civilization, these questions may also be important by to all by definition.
Using a Functional Modeling Framework to Compare Some Leading Models of Consciousness
Authors: Williams Andy E
Published: April 2020

A recently developed Functional Modeling Framework (FMF) for defining models of consciousness and cognition proposes to have the capacity to represent all models of consciousness and cognition and proposes to define the criteria for a model of consciousness to have the potential for self awareness. The FMF provides a single mathematical framework for defining models of consciousness that is human-centric in being independent of assumptions made by any specific model. This human-centric approach enables different models to be more easily compared so research on consciousness can reliably converge on a single understanding, enabling the possibility of massively collaborative interdisciplinary projects to research, and implement a model of consciousness and cognition where not possible before. Some functional components of the FMF remain to be validated. However even without validating the entire framework using some subset of the framework is still useful as a common basis for comparing models of consciousness. This paper demonstrates the comparison of three leading model of consciousness within the subset of this framework that has been validated by many years of tradition.
Affirming Basic Psychological Needs Promotes Mental Well-Being During the COVID-19 Outbreak
Authors: Cantarero Katarzyna , van Tilburg Wijnand A. P. , Smoktunowicz Ewelina
Published: April 2020

We tested if challenges to basic psychological needs (autonomy, competence, relatedness) during the COVID-19 pandemic undermines people’s mental well-being. Furthermore, we tested if an intervention, affirmation of these psychological needs, counteracts this negative impact. Results of Study 1 (N = 153) showed that higher levels of satisfaction of basic psychological needs was related to higher mental well-being during the COVID-19 outbreak. In Study 2 (N = 215) we employed an online intervention enhancing these basic psychological needs. We found increased mental well-being through bolstered relatedness in particular. The intervention also decreased perceived stress. Both studies showed that mental well-being during the COVID-19 pandemic is positively related to the ability to work as usual and the number of people contacted via phone or Internet, but not in person.

Published: April 2020

Developmental invariance is important for making valid inferences about child development from longitudinal data; however, tests of it are rare. We tested developmental and gender invariance for one of the most widely used measures of child mental health: the parent-reported Strengths and Difficulties Questionnaire (SDQ). Using data from the large UK population-representative Millennium Cohort Study (N= 10,207; with data at ages 3,5,7,11, 14, and 17) we tested configural, metric, scalar, and residual invariance in emotional problems, conduct problems, hyperactivity/inattention, prosociality, and peer problems. We found that the SDQ showed poor fit at age 3 in both males and females and at age 17 in males; however, it fit reasonably well and its scores were measurement invariant up to the residual level across gender at ages 5, 7,11, and 14. Longitudinal invariance analyses suggested that scores were also longitudinally measurement invariant across this age range up to the partial residual level. Results suggest that the parent-reported SDQ can be used to yield valid estimates of developmental trajectories of emotional problems, conduct problems, hyperactivity/inattention, prosociality, and peer problems and their gender differences across the age range 5 to 14 using a latent model. Developmental differences outside of this range may; however, partly reflect that markers of these constructs are not well-described by the same five-dimensional model as can be used in the age 5 to 14 range.
New Design of 60 GHz MIMO 2x4 Patch Rectangular Antenna Array for Wireless Gigabit (Wi-Gig) Application
Authors: Rahayu Yusnita
Published: April 2020

Nowadays, most antenna researchers over the world are focusing on the design of the antenna for the fifth generation (5G) application (indoor and outdoor). High intensive research on 60 GHz antenna for high data rate indoor communication is becoming a trending topic. The high propagation loss at this band is the most challenging. The antenna needs to have higher gain to overcome the loss. Such antenna designs have been proposed recently. This paper, a new MIMO 2x4 patch rectangular antenna operating at 60 GHz is designed for Wi-Gig application. The rectangular patch antenna has 1.75 mm x 1.54 mm of size, printed on Rogers Duroid RT 5880 substrate, the dielectric constant of 2.20 and loss tangent of 0,0009. The antenna was designed and simulated using CST simulation software.  The simulated return loss showed a very consistent characteristic. The return loss reached −30 dB at 60 GHz.  The broad bandwidth obtained is 4.3 GHz concerning -10 dB. The omnidirectional radiation pattern with 13.4 dBi of gain is obtained. This antenna meets the Wi-Gig requirement.

Published: April 2020

The type of insulation gases that are usually used in the power circuit breaker (circuit breaker) is the sulfur hexafluoride (SF6) gas, nitrogen (N2) and carbon dioxide (CO2). Most of the electric power systems are using insulating materials such as sulfur hexafluoride (SF6). Sulfur hexafluoride gas (SF6) has a higher dielectric strength than the air. However, Sulfur hexafluoride (SF6) gas is not friendly environmentally and very impact on global warming. The purpose of this study was to test the breakdown voltage of nitrogen gas (N2) (more friendly environmental) as alternative insulation of sulfur hexafluoride (SF6) gas. This study was used sphere and needle electrodes with a distance of 0.5-2 cm and a pressure of 1-4 bar; it was tested for 20 times. From the test results, it obtained that the breakdown voltage of sphere electrodes is more significant than the needle electrodes. Sphere and needle electrodes with a distance of 2 cm and a pressure of 4 bar have a most excellent value of breakdown voltage at the voltage of 140 kV and 79 kV, respectively.

Published: April 2020

This paper presents a study of the specific disciplinary competencies required of library programming professionals and the training pathways where they develop those skills. Most existing competency frameworks focus on general library service or audience, rather than the specializations required for public programming. Reflecting the emerging importance of programming to libraries’ service model, this US research study demonstrates that excellence in programming requires a unique set of competencies not found in other areas of library practice. The evidence shows that most public-programming competencies are learned outside of MLIS training but could be introduced as an MLIS concentration or learned as professional development.

Introduction. It is known that patients with ischemic heart diseases have endothelial dysfunction, but there is lack of research about microcirculation in these patients with diffuse liver diseases, especially diagnosed with digital capillaroscopy. Aim. To investigate hemodynamic disorders and microcirculation in patients with chronic ischemic heart disease depending on the presence of diffuse liver diseases and its severity with the digital capillaroscopy. Materials and methods. Our prospective study included 187 patients according to the criteria of inclusion. The data of echocardiography and digital capillaroscopy were analysed. Results. In our research in patients with ejection fraction less than 40% there was revealed thickening of the wall of the left ventricle, low blood supply in arterial and venous parts of capillaries. Patients with ejection fraction less than 40% and progressive diffuse liver diseases had advanced thickening of the wall of the left ventricle. Patients with liver cirrhosis had more adverse changes in hemodynamics. Patients with ischemic heart disease and diffuse liver disease had the worst capillary blood supply. Patients with ejection fraction less than 40% and diffuse liver diseases had structural changes of capillaries such as bi-, trifurcation and bushy forms. Conclusions. So, diffuse liver diseases, especially severe, cause endothelial dysfunction in patients with ischemic heart diseases. Digital capillaroscopy is a noninvasive method for microcirculation diagnosis and patients’ monitoring.

In addition to diseases, the examination of the gallbladder and extrahepatic biliary tract reveal functional changes (excesses of the gallbladder, stagnation of bile) and individual anatomical features that do not affect the functioning of the system as a whole, do not cause painful sensations, but in unfavorable conditions lead to the development of diseases (formation of gallbladder stones, mechanical obstacles and acute inflammatory processes). In the course of our research, we determined the frequency of occurrence of asymptomatic bile stagnation, depending on the localization of excesses of the gallbladder in adults without pathology of the hepatobiliary system. The protocols of ultrasound examination of adults with pathology of the hepatobiliary system, performed with the ultrasound machine RadmirUltimaPU, were analyzed. In the first age group, combination of gallbladder excess and bile stagnation was found in 7.1% (both men and women) of all surveyed. In the second age group, this indicator was 50% for men and 35.7% for women. Excesses of the gallbladder is more common in males - 21.6%, in women - 15%. Their frequency increases with age. The timely detection of functional features of the gallbladder in combination with the application of preventive recommendations can prevent the development of the disease.

A war correspondent has no border, no gender, no religion or race. The only thing a war reporter has - the skills of delivering truth, reflection of the reality in the way it is.The soviet space was absolutely closed to journalism and combat women journalists’ involvement in wars. The field almost consisted of males. Consequently, it seems impossible to analyze and compare the technique of writing of American and SovietWomen. If America freely accepts women for being actively involved in covering war activities, the Soviets obviously refused to do so.The role of a war correspondent is much bigger than one can suppose. Being a war reporter is more than implementing their responsibilities. It goes deeper into the history. A professional combat reporter is a historian facing the history and keeping it for the next generation.The paper considers advantages and disadvantages of being a female combat correspondent in the Soviet space and the United States of America.The role of American and Soviet women reporters in covering WWII.

OBJECTIVE

Myelopathy selectively involving the lower extremities can occur secondary to spondylotic changes, tumor, vascular malformations, or thoracolumbar cord ischemia. Vascular causes of myelopathy are rarely described. An uncommon etiology within this category is diaphragmatic crus syndrome, in which compression of an intersegmental artery supplying the cord leads to myelopathy. The authors present the operative technique for treating this syndrome, describing their experience with 3 patients treated for acute-onset lower-extremity myelopathy secondary to hypoperfusion of the anterior spinal artery.

METHODS

All patients had compression of a lumbar intersegmental artery supplying the cord; the compression was caused by the diaphragmatic crus. Compression of the intersegmental artery was probably producing the patients’ symptoms by decreasing blood flow through the artery of Adamkiewicz, causing lumbosacral ischemia.

RESULTS

All patients underwent surgery to transect the offending diaphragmatic crus. Each patient experienced substantial symptom improvement, and 2 patients made a full neurological recovery before discharge.

CONCLUSIONS

Diaphragmatic crus syndrome is a rare or under-recognized cause of ischemic myelopathy. Patients present with episodic acute-on-chronic lower-extremity paraparesis, gait instability, and numbness. Angiography confirms compression of an intersegmental artery that gives rise to a dominant radiculomedullary artery. Transecting the offending diaphragmatic crus can produce complete resolution of neurological symptoms.

OBJECTIVE

The aim of this study was to investigate sagittal alignment and compensatory mechanisms in patients with monosegmental spondylolysis (mono_lysis) and multisegmental spondylolysis (multi_lysis).

METHODS

A total of 453 adult patients treated for symptomatic low-grade spondylolytic spondylolisthesis were retrospectively studied at a single center. Patients were divided into 2 subgroups, the mono_lysis group and the multi_lysis group, based on the number of spondylolysis segments. A total of 158 asymptomatic healthy volunteers were enrolled in this study as the control group. Radiographic parameters measured on standing sagittal radiographs and the ratios of L4–S1 segmental lordosis (SL) to lumbar lordosis (L4–S1 SL/LL) and pelvic tilt to pelvic incidence (PT/PI) were compared between all experimental groups.

RESULTS

There were 51 patients (11.3%) with a diagnosis of multi_lysis in the spondylolysis group. When compared with the control group, the spondylolysis group exhibited larger PI (p < 0.001), PT (p < 0.001), LL (p < 0.001), and L4–S1 SL (p = 0.025) and a smaller L4–S1 SL/LL ratio (p < 0.001). When analyzing the specific spondylolysis subgroups, there were no significant differences in PI, but the multi_lysis group had a higher L5 incidence (p = 0.004), PT (p = 0.018), and PT/PI ratio (p = 0.039). The multi_lysis group also had a smaller L4–S1 SL/LL ratio (p = 0.012) and greater sagittal vertical axis (p < 0.001).

CONCLUSIONS

A high-PI spinopelvic pattern was involved in the development of spondylolytic spondylolisthesis, and a larger L5 incidence might be associated with the occurrence of consecutive multi_lysis. Unlike patients with mono_lysis, individuals with multi_lysis were characterized by an anterior trunk, insufficiency of L4–S1 SL, and pelvic retroversion.
