Spontaneous Color Polarization as A Modus Originis of the Dynamic Aether
Authors: Balakin Alexander , Kiselev Gleb
Published: July 2020

We suggest the phenomenological model of emergence of the dynamic aether as a result of decay of the SU(N) symmetric field configuration containing the multiplet of vector fields. The scenario of the transition to the dynamic aether, which is characterized by one unit timelike vector field that is associated with the aether velocity, is based on the idea of spontaneous color polarization analogous to the spontaneous electric polarization in ferroelectric materials. The mechanism of spontaneous color polarization is described in the framework of anisotropic cosmological model of the Bianchi-I type; it involves consideration of the idea of critical behavior of the eigenvalues of the tensor of color polarization in the course of the Universe accelerated expansion. The interim stage of transition from the color aether to the canonic dynamic aether takes the finite period of time, the duration of which is predetermined by the phenomenologically introduced critical value of the expansion scalar.
The Presence of Rabies Virus-Neutralizing Antibody in Wild Boars (Sus scrofa), a Non-Target Bait Vaccine Animal in Korea
Authors: Kim Ha-Hyun , Yang Dong-Kun , Wang Ja-Young , An Dong-Jun
Published: July 2020

Oral vaccination with bait is an effective method to prevent rabies in wildlife, but non-target wild animals may also ingest the bait vaccine. In Korea, the target animal of the rabies bait vaccine is the raccoon dog (Nyctereutes procyonoides). Bait vaccines have been distributed in Korea for 20 years; although wild raccoon dogs have been tested for antibodies, rabies antibodies have never been investigated in non-target wild animals. Therefore, this study investigated rabies antibody formation in wild boars (Sus scrofa), which is likely the main competitor for the bait vaccine in Korea. In bait areas, 20 of 109 wild boars (18.3%) were seropositive, and 39 of 470 wild boars (8.3%) in non-bait areas were also seropositive. These results provide insights regarding bait uptake or vaccination in non-target wild boars.

Published: July 2020

This research study was carried out to investigate the characteristics of drought based on the joint distribution of two dependent variables, the duration and severity, in the Eastern Cape Province, South Africa. The drought variables were computed from the Standardized Precipitation Index for 6- and 12-month accumulation period (hereafter SPI-6 and SPI-12) time series calculated from the monthly rainfall data spanning the last five decades. In this context, the characteristics of climatological drought duration and severity were based on multivariate copula analysis. Five copula functions (from the Archimedean and Elliptical families) were selected and fitted to the drought duration and severity series in order to assess the dependency measure of the two variables. In addition, Joe and Gaussian copula functions were considered and fitted to the drought duration and severity to assess the joint return periods for the dual and cooperative cases. The results indicate that the dependency measure of drought duration and severity are best described by Tawn copula families. The dependence structure results suggest that the study area exhibited low probability of drought duration and high probability of drought severity. Furthermore, the multivariate return period for the dual case is found to be always longer across all the selected univariate return periods. Based on multivariate analysis, the study area (particularly Buffalo City, OR Tambo and Alfred Zoo regions) is determined to have higher/lower risks in terms of the conjunctive/cooperative multivariate drought risk (copula) probability index. The results of the present study could contribute towards policy and decision making through e.g., formulation of the forward-looking contingent plans for sustainable management of water resources and the consequent applications in the preparedness for and adaptation to the drought risks in the water-linked sectors of the economy.
Design Thinking Methodology to Achieve Household Engagement in Urban Water Sustainability in the City of Huelva (Andalusia)
Authors: Bermejo-Martín Gustavo , Rodríguez-Monroy Carlos
Published: July 2020

To advance to water sensitive cities (WSC) it will be necessary to achieve the commitment of the citizens, involving them in this transition. Citizen participation is considered essential, and one of the possible approaches to achieve this is through Design Thinking (DT), a human-centered methodology that allows creating a framework to develop the hydrosocial contract. The Suez group proposed the challenge of collecting initiatives to achieve more efficient use of urban water in homes, by conducting a pilot in one of its investee companies, Aguas de Huelva. Our research proposal, selected by the Suez group, to achieve greater engagement of households regarding efficient water use, was to develop a web-based prototype applying DT methodologies, which would allow us to generate new messages and meanings regarding water, producing an innovation of meaning that would enable tracking the progress of the results. This article describes the approved framework to carry out the pilot experience in the homes of the city of Huelva in Andalusia, Spain.
Ten Principles to Determine Environmental Flow Requirements for Temporarily Closed Estuaries
Authors: Adams Janine Barbara , Van Niekerk Lara
Published: July 2020

Temporarily closed estuaries require seasonal opening to tidal flows to maintain normalecological processes. Each estuary has specific environmental flow (EFlow) requirements basedon the relationship between freshwater inflow, coastal dynamics, rate of sandbar formation,and the open/closed state of the mouth. Key abiotic processes and ecosystem services linkedto mouth state were highlighted. We reviewed completed EFlow requirement studies for temporarilyclosed estuaries in South Africa and found that the formulation of these requirements shouldconsider the timing and magnitude of flows in relation to the morphology of an estuary, its mouthstructure, catchment size, and climate. We identified ten key principles that could be adapted tosimilar systems in equivalent climatic settings. Principle 1 recognizes that each estuary is unique interms of its EFlow requirements because size, scale, and sensitivity of core elements to freshwaterinflow are specific for each system; EFlows cannot be extrapolated from one estuary to another.Principle 2 highlights the importance of baseflows in keeping an estuary mouth open because a smallreduction in flow can cause the mouth to close and alter essential ecological processes. Principle 3outlines the role of floods in resetting natural processes by flushing out large volumes of sedimentand establishing the equilibrium between erosion and sedimentation. Principle 4 emphasizes the needfor open mouth conditions to allow regular tidal flushing that maintains water quality throughreducing retention times and preventing the onset of eutrophic conditions. Principle 5 advisesartificial breaching to be practiced with caution because execution at low water levels encouragessedimentation that reduces the scouring eect of flushing. Principle 6 holds that elevated inflowvolumes from wastewater treatment works or agricultural return flows can increase the frequency ofmouth opening and cause ecological instability. Principle 7 states that water released from dams tosupply the environmental flow cannot mimic the natural flow regime. Principle 8 specifies the needfor short- and long-term data to increase the confidence levels of EFlow assessments, with data tobe collected during the open and closed mouth states. Principle 9 advocates the implementation ofa monitoring program to track the achievement of EFlow objectives as part of a strategic adaptivemanagement cycle. Finally, Principle 10 recommends the adoption of a holistic catchment-to-coastmanagement approach underpinned by collaboration with regulatory authorities and stakeholdersacross a range of sectors. These principles can be used to guide the formulation and managementof EFlows, an essential strategy that links the maintenance of estuarine ecological integrity withsocial well-being.
Localization of Groundwater Contaminant Sources Using Artificially Enhanced Catchment

Published: July 2020

The localization of groundwater contaminant sources is the first and most fundamental step when dealing with site contamination problems. This paper presents a novel approach for groundwater pollution source identification in a site with low-velocity groundwater in which a strategy of an artificially enhanced catchment is adopted. The distance from a pumping well (artificial sink) to the source zone (unknown source) is calculated by integrating the concentration time series and well flow. Then, the orientation of the source well is delineated by applying the method of distance intersection. This method is suitable for an approximately homogeneous aquifer with average hydraulic conductivity ranging from 1 × 10−6 to 1 × 10−5 m/s and a contaminant whose transport process can be generalized to convective migration. The developed method was applied to an industrial contaminated site using three pumping wells and two observation wells. The results demonstrated that four potential source positions were identified. Among these, two positions situated near the production workshop were excluded by observation well responses. The remaining two positions located near the drain were identified as preferred treatment sources. Electrical prospecting showed source orientation consistent with the artificially enhanced catchment results. This proved that the method is effective and provides an alternative tool to help solve the problem of source identification in the first stage of remediation in sites with low-velocity groundwater.
Frequency Trend Analysis of Heavy Rainfall Days for Germany
Authors: Deumlich Detlef , Gericke Andreas
Published: July 2020

Climate change is expected to affect the occurrence of heavy rainfall. We analyzed trends of heavy rainfall days for the last decades in Germany. For all available stations with daily data, days exceeding daily thresholds (10, 20, 30 mm) were counted annually. The Mann–Kendall trend test was applied to overlapping periods of 30 years (1951–2019). This period was extended to 1901 for 111 stations. The stations were aggregated by natural regions to assess regional patterns. Impacts of data inconsistencies on the calculated trends were evaluated with the metadata and recent hourly data. Although the trend variability depended on the chosen exceedance threshold, a general long-term trend for the whole of Germany was consistently not evident. After 1951, stable positive trends occurred in the mountainous south and partly in the northern coastal region, while parts of Central Germany experienced negative trends. The frequent location shifts and the recent change in the time interval for daily rainfall could affect individual trends but were statistically insignificant for regional analyses. A case study supported that heavy rains became more erosive during the last 20 years. The results showed the merit of historical data for a better understanding of recent changes in heavy rainfall.

Published: July 2020

El uso de semillas de calidad representa el inicio de un cultivo rentable. Este estudio se hizo para identificar la etapa de cosecha más apropiada y obtener la mejor calidad de semilla. En Texcoco, México, en condiciones de invernadero se estudió la evolución de la calidad física y fisiológica de semillas de tres tipos de chile (Capsicum annuum): de Árbol, Ancho y Guajillo, obtenidas de frutos cosechados en cinco etapas de desarrollo: (E1) 25 y (E2) 40 d después de antesis, (E3) cuando el fruto comenzó a cambiar de color, (E4) cuando el fruto cambió totalmente de color, y (E5) cuando el fruto estaba totalmente seco. También se evaluaron dos etapas de extracción de semilla: inmediatamente después de la cosecha de fruto (EI) y 15 d después (EP). El contenido de humedad de la semilla fue 7.6 % en todos los tratamientos. Las variables de calidad física (peso de 1000 semillas y el peso volumétrico) y fisiológica (germinación y velocidad de germinación) siguieron una tendencia de incremento sigmoidal, cuya fase de rápido crecimiento fue hasta E3 para la calidad física y hasta E4 para la calidad fisiológica. La extracción en EP mejoró significativamente la calidad fisiológica, pues la semilla de frutos cosechados en E3 alcanzó un promedio de 93.4 % de germinación, muy superior a la obtenida en las semillas de frutos cosechados en EI (6.7 %). La mejor calidad fisiológica de semillas en los chiles Ancho y de Árbol se alcanzó en frutos cosechados en E4 combinada con extracción EP, mientras que en Guajillo la mejor combinación fue E3 y EP.

Published: July 2020

Un problema frecuente en los sistemas hidropónicos en los que se recircula la solución nutritiva (sistemas cerrados) es un menor rendimiento y calidad respecto a los sistemas sin recirculación (abiertos), lo cual es atribuido a que las soluciones nutritivas se desequilibran conforme se desarrolla el cultivo, a la vez que se incrementa el riesgo de diseminación de enfermedades. El objetivo de la investigación fue evaluar la factibilidad de sistemas hidropónicos cerrados para alcanzar rendimientos de pepino (Cucumis sativus L.) similares a los que se obtienen con sistemas abiertos, mediante el acortamiento del ciclo de cultivo. Se compararon tres modalidades de sistemas cerrados (raíz flotante, cultivo en bolsa con sustrato y cultivo en cama con sustrato) y dos abiertos (cultivo en bolsa y en cama con sustrato), bajo un diseño de bloques completos al azar con cinco repeticiones. Se encontró que tanto el crecimiento de la planta como el rendimiento de fruto de pepino fueron similares entre los sistemas con y sin recirculación de la solución nutritiva en bolsa y cama, pero con raíz flotante se alcanzó mayor acumulación de materia seca y mayor rendimiento por unidad de superficie. Los sistemas cerrados permitieron un ahorro superior a 20 % en agua y de 25 % en nutrimentos, en comparación con los sistemas abiertos.

En los tres tipos de selección recurrente para aptitud combinatoria en el maíz (Zea mays L.) se usan como unidades de selección a líneas S1, mientras que los criterios de selección son los mestizos hechos por las cruzas entre las unidades de selección y los probadores: una variedad de polinización libre, una línea altamente endogámica y la población B para las líneas S1 derivadas de A, y la población A para las líneas S1 derivadas de B. La endogamia que se genera ocurre por los cruzamientos entre las líneas seleccionadas S1 en los tres tipos de selección recurrente, aunque las líneas S1 no serán las mismas en los tres tipos de selección. En los cálculos que aquí se presentan se usaron 20 líneas S1 y 20 plantas por línea, que produjeron una alta endogamia (0.59) en el ciclo 10 de selección. Para reducir la endogamia a 0.20 basta con hacer solamente dos o tres ciclos de selección.

La Lega “nazionale” di Salvini alla conquista elettorale del Meridione
Authors: De Luca Roberto , Fruncillo Domenico
Published: July 2020

In the last European elections the League became the first party in Italy also because, for the first time, it collected a large number of votes in the South, exceeding the 20% of votes in the Southern italian regions. In this article we try to evaluate whether that success is temporary or if it will consolidate over time. In other words, the central question is whether the vote to the Leauge party in the South of Italy is weak and volatile or it represents the first moment of its establishment also in these areas of the Country. In details, we try to verify if the success of the Leauge party in the South of Italy can be related to traditional aspects of the parties’ organization, such as the territorial root and the recruitment of political personnel who obtain in the electoral competition personal votes which improve the success of the list. The analysis was conducted through out macro and micro analysis tools. The analysis of the preference vote distribution highlights the electoral contribution offered by all the candidates to the European Parliament by region and by size of the municipalities. The description of some emblematic local cases describes the dynamics through which some local candidates for the European Parliament have contributed to increase the political consensus of the League party in the South of Italy.

Outcome in Patients with Acute Limb Ischemia Post Hybrid Procedure Compared to Surgical Thrombectomy
Authors: Nugroho Nyityasmono , Nugroho Nyityasmono Tri , Pratama Dedy
Published: July 2020

Introduction: Acute limb ischemia (ALI) is characterized by decreased perfusion to extremities in the form of acute ischemia and the presence of acute thrombus which may endanger the viability of the extremities. Therapeutic modalities are various including intraarterial thrombolysis with or without the help of ultrasonography and the use of thrombectomy instruments. However, due to the high morbidity and mortality rate, a new technique called the hybrid procedure is introduced. This procedure is a combination between endovascular management to correct the abnormalities with the help of angiography as well as thrombectomy surgical management, in the same time. Therefore, it is necessary to conduct a literature search related to the case we are reporting, to determine whether hybrid procedure or thrombectomy only is the best management for ALI. This study aims to determine the best management for the case being reported according to literature search and critical reviews collected from medical research database.

Method: From the data collected, there was one interesting case, which is a case about acute limb ischemia, and the following operative management. Afterwards, a literature search was conducted to obtain articles related to the case, and critical review was made regarding the selected article.

Results: At the end of the literature search, we found two articles which showed better outcome on hybrid procedure compared to surgical thrombectomy. Compared to the group who underwent thrombectomy, there was decreased 30-days mortality in the group who underwent the hybrid procedure (3.3% vs 4.4%, p-value 0.05), decreased incidence of amputations after 30 days (6.49% vs 13.5%, p-value 0.023), increased limb salvage (91.9% vs 82.3%, p-value 0.03, 95% CI), and decreased two-years mortality (18.7% vs 40.5%; p– value <0.001).

Conclusion: Critical review on articles obtained from literature search in online database showed that the outcome hybrid procedure was better than surgical thrombectomy only.

Introduction. The cause of blood vessels abnormalities in the retina in addition to diabetes is obstruction in the veins. In general, retinal vein blockages are distinguished in two types i.e. blockage of retinal veins (BRVO) and obstruction of the central vein of the retina (CRVO). Reported a case of a central retinal vein occlusion with intravitreal anti-injection treatment of a VEGF Bevacizumab.

Case presentation. A man, Mr. T, aged 52 years, with an address outside the city, the work of the foreman, came to RSMH's eye on October 2014. Anamnesis the main complaint of the right eye eyesight was suddenly dark since, one day before. One day before go to hospital, the sufferer complained about the right eye suddenly until it felt dark. He also complain often headaches without nausea and vomiting since before his right eye vision becomes blurred. Intravitreal anti-VEGF injection in these patients is planned to be re-done 4-6 weeks after the first injection if there has been no improvement in his vision. Evaluation of the effectiveness of intravitreal Bevacizumab anti-VEGF therapy through sharp improvement of vision, clinical features and anatomical improvement.

Conclusion. A case of central retinal vein occlusion was reported in a 52-year-old male. After anamnesis, ophthalmologic examination and investigations, a diagnosis of CRVO is managed by intravitreal Anti VEGF injection.

Published: July 2020

Introduction. Retinal Vein Occlusion (RVO) is the second most common retinal blood vessel disease after diabetic retinopathy. CRVO is an acute blockage of the central retinal vein that causes abnormalities in the retina, characterized by sudden decreased vision. Based on the potential for vision loss from this retinal disease, proper diagnosis and management is needed to prevent further complications.

Case Presentation. A man, age 50 years old, a civil servant, came to the eye clinic of Mohammad Hosein Hospital on February 2017. The main complaint was vision of right eye suddenly blurred since 5 months before. Based on the above examination found decreased vision in one eye, with visual acuity better than 6/60 and no RAPD. The funduscopic examination above shows the presence of dilatation and tortousity in the central retinal vein, dot / blot bleeding and flame shaped hemorrhages in all quadrants, exudates, neovascularization of the retina and optic disk, and the presence of edema in the optic disc and macula.

Conclusion. Management performed on these patients is by performing a Pan-Retinal Photocoagulation (PRP) laser and Grid-Pattern Photocoagulation. The selection of this therapy is based on the consideration that the patient has been suffering from CRVO for more than 3 months.

Authors: Rika Anggraini  , Ansyori AK , Amin Ramzi
Published: July 2020

Introduction. Diagnosis of vitreous bleeding is generally straightforward and  it can be made through history, ophthalmological examination and fundoscopy. However, the management is determined by the underlying etiology. The most common causes as factors that cause opposite vitreous bleeding include retinopathy of proliferative diabetes, posterior vitreous detachment (PVD) and trauma in 59-88.5% of cases. Reported a case of vitreous hemorrhage due to closed eyeball trauma performed by pars plana vitrectomy and endolaser with significant vision improvement.

Case Presentation. A male, 21 years old, student, lived in suburban, came to the Polyclinic of RSMH on July 2019. Approximately 1 month ago the patient complained that his right eye vision suddenly felt blurry after being hit by volleyball from the front from a distance of 1 meter while playing volleyball with his friends. Patients complain of the view of the right eye as if it were covered with a red shadow accompanied by pain around the right eye. Ophthalmological examination obtained vision of this patient is a wave of the hand that is 1/300 in the right eye and 6/6 in the left eye that shows the disorder is unilateral with a fairly poor decrease in vision. During intraoperative right eye hemorrhage was found to nearly cover the retina with the source of bleeding in peripheral retinal blood vessels which when found intraoperatively were not found extravasation or active bleeding.

Conclusion. The operative action of pars plana vitrectomy gives a clinically significant result that is obtained very good sharp eyesight and from the examination results obtained echofree on vitreous. Proper timing is very important in determining the management of vitreous bleeding in order to get good results and minimize the risk of complications that can occur.

Published: July 2020

Abstract

Background: Diabetes mellitus (DM) have a direct effect to retinal neural tissue. Diabetic retinopathy slowly proggress with reserved visual acuity and no symptoms in early stage. Retinal nerve fiber layer thickness significantly decrease in type 2 diabetes mellitus patients related to glycemic blood level.

Purpose: To analyze the relationship between HbA1c level and retinal nerve fiber layer thickness in diabetic retinopathy patients.

Methods: A cross sectional analytical study was conducted in RSUP dr. Mohammad Hoesin Palembang from October 2017 until March 2018. Sixty eight type 2 diabetes mellitus patients consist of various grade of diabetic retinopathy. Measurement of HbA1c level was performed on these samples and retinal nerve fiber layer thickness was measured by Optical Coherence Tomography (OCT).

Results: There is a significant relationship between duration of DM with RNFL thickness (p = 0,002). There is a significant relationship between hypertension with RNFL thickness (p = 0,007). There is a significant relationship between HbA1c level with RNFL thickness in all quadrants (superior, nasal, inferior quadrants p

= 0,000, temporal quadrant p = 0,011). The most important factor of RNFL thinning in superior, nasal and inferior quadrants is HbA1c level (superior and nasal adjusted p value 0,002, inferior adjusted p value 0,002) while in temporal quadrant is hypertension (adjusted p value 0,042).

Conclusion: There is a significant relationship between HbA1c level with RNFL thickness in all quadrants in which the patients with HbA1c > 7% have a higher risk of thinner RNFL compared to patients with HbA1c ≤ 7%.

ABSTRACT

 

Objective: To determine the relationship of serum IgE levels and age-related cataract at the Special Eye Hospital in Palembang.

Methods: An observational study with cross-sectional design study was undertaken in October 2018 to May 2019 at the Special Eye Hospital in Palembang. There were 86 patients who met the inclusion and exclusion criteria. The independent variable in this study is the level of serum immunoglobulin E and the dependent variable is senile cataract. The data analysis has been done with diagnostic research by SPSS version 20.0 (SPSS, Inc Chicago, Illinois).

Results: Thirty five people suffered from senile cataracts and fifty one people did not suffer from cataracts. The mean IgE level in senile cataract patients was 5.129 ± 1.588 ng /mL while in patients without cataracts it was 5.001 ± 1.564 ng/mL. There was no difference in IgE levels between senile cataract patients and patients without cataracts (p = 0.891). With statistical analysis using the ROC curve it was found that the IgE concentration cut off point was 5.046 ng/mL. There were 54.3% of senile cataract patients and 51% of patients without cataracts who had IgE levels > 5.046 ng/mL. Patients with IgE levels > 5.046 had an almost equal risk of senile cataracts compared to patients with IgE levels <5.046 (PR = 1.142 (CI95% 0.482 - 2.705; p = 0.935).

Conclusion: There is no significant relationship between IgE levels and the incidence of senile cataracts.

Published: July 2020

ABSTRACT

Introductions: Laser in situ Keratomileusis (LASIK) is the most common refractive surgery to treat myopia. One of the most common complain after this procedure is blurry near- vision.

Objectives: To evaluate the role of accommodation amplitude (AA) in myopic patients before and after LASIK and its effect to blurry near-vision in myopic patients after LASIK

Methods: Patients with myopia who underwent LASIK procedure in Sriwijaya Eye Center Hospital from January to February 2018 studied prospectively. AA was assessed before and after LASIK with 1 day, 1 week and 1 month. Myopia degree, intraocular pressure (IOP), age, gender, ablation and corneal profile were also assessed.

Results: A total 52 eyes from 32 patients were included. Visual acuity (VA) of all sample were significantly improve in 1 day after LASIK (p 0,001). Mean AA in myopic patients before LASIK 9,25 D and AA 1 day after LASIK were all significantly decrease into 9,00D (p 0,012) which can cause in blurry near- vision after LASIK. In 1 month followed-up, mean AA is significantly improved into 11,00 D (p 0,000) with no complain. Other factor that affect the changing AA were corneal cell density (CD), IOP and AA before LASIK.

Conclusions: There is significant AA difference in myopic patients before and after LASIK. Blurry near-vision after LASIK is caused by AA adaptation mechanism after LASIK.

High-resolution LA-ICP-MS trace-element mapping of magmatic biotite: A new approach for studying syn- to post-magmatic evolution
Authors: Azadbakht Zeinab , Lentz David R.
Published: July 2020

Biotite grains from 22 felsic intrusions in New Brunswick were mapped in situ using a laser ablation-inductively coupled plasma-mass spectrometer (LA-ICP-MS). We investigated the extent to which biotite can retain its magmatic zoning patterns and, where zoning does exist, how it can be used to elucidate early to late stage, syn-magmatic to post-crystallization processes. Although the major element and halogen contents of the examined biotite phenocrysts are homogeneous, two-thirds of the grains display trace-element zoning for Ba, Rb, and Cs. The results also indicated that zoning is better retained in larger grains (i.e., > 500 × 500 μm) with minimal alteration and mineral inclusions.

An exceptionally well-zoned Li-rich siderophyllite from the Pleasant Ridge topaz granite in southwestern New Brunswick shows Ti, Ta, Sn, W, Cs, Rb, and V (without Li or Ba) zoning. Cesium values increase from 200 to 1400 ppm from core to rim. Conversely, Sn and W values decrease toward the rim (50 to 10 and 100 to 10 ppm, respectively). Tantalum and Ti values show fewer variations but drop abruptly close to the rim of the grain (100 to 20 and 2000 to 500 ppm, respectively). These observations may indicate crystallization of mineral phases with high partition coefficients for these highly incompatible elements (except Ti) (e.g., cassiterite and rutile) followed by fractionation of a fluid phase at a later stage of magma crystallization. The preservation of zoning may indicate rapid cooling post-crystallization of the parent magma.
Source credibility modulates the validation of implausible information
Authors: Wertgen Andreas G. , Richter Tobias
Published: July 2020

Validation of text information as a general mechanism for detecting inconsistent or false information is an integral part of text comprehension. This study examined how the credibility of the information source affects validation processes. Two experiments investigated combined effects of source credibility and plausibility of information during validation with explicit (ratings) and implicit (reading times) measurements. Participants read short stories with a high-credible versus low-credible person that stated a consistent or inconsistent assertion with general world knowledge. Ratings of plausibility and ratings of source credibility were lower when a credible source stated a world-knowledge inconsistent assertion compared with a low-credible source. Reading times on target sentences and on spillover sentences were slower when a credible source stated an assertion inconsistent with world knowledge compared with a low-credible source, suggesting that source information modulated the validation of implausible information. These results show that source credibility modulates validation and suggest a bidirectional relationship of perceived plausibility and source credibility in the reading process.

BACKGROUND & OBJECTIVE: Saline hysterosonography is a simple and cost-eﬀective method with high sensitivity to detect uterine abnormalities causing postmenopausal bleeding. The objective of this study was to evaluate the diagnostic accuracy of saline hysterosonography in detecting endometrial hyperplasia in women with postmenopausal bleeding by taking histopathology as a gold standard.

METHODOLOGY: A hundred and twenty (120) cases were enrolled from the outpatient and inpatient department of obstetrics and gynecology. Proper history and relevant examination of the patient was done. Then preparations were made for the procedure. The patient was counseled and the technique explained to her. Then Foley catheter no 12 was passed in cervix and sonography was done while instilling normal saline through a cervical catheter and scan pictures were frozen and results were given by expert gynecologist of Allied Hospital, Faisalabad. Histopathology specimen was sent to the pathology lab.

RESULTS: Sensitivity, speciﬁcity, positive predictive value, negative predictive value, and diagnostic accuracy of saline hysterosonography in detecting endometrial hyperplasia was recorded as 96.15%,91,49%,75.76%,98.85%, and 92.5% respectively.

CONCLUSION: Saline hysterosonography has high sensitivity to detect uterine hyperplasia. It can be used as a cost eﬀective alternative to hysteroscopy in many units in Pakistan.
