The time of the Covid-19 pandemic stopped the theatre process and opened the way for new forms and techniques in the virtual environment, updating the concept of e-theatre. The research of these processes from an aesthetic point of view has also stimulated the development of a new discourse in Latvian theatre science, analyzing the technical solution of virtual or e-productions, the impact on viewers, as well as other aspects related to theatrical manifestations in the virtual environment. The aim of the article is to provide an overview of the aesthetic strategies and means of expression in Latvian e-theatre, researching this process from a semiotic approach (performance signs and sign systems in the virtual environment), as well as a phenomenological take (the impact of e-performances on the spectator). In the spring of 2020, soon after the Covid-19 restrictions, virtual experiments quickly developed in Latvian theatre. In the context of the global pandemic caused by Covid-19, we can talk about a complete transition of the theatre to a virtual space, forcibly changing the forms of performances to digital formats that do not require viewers and actors to be in the same room. At the same time, this forced transition of the theatre to the digital environment is connected with other risks, such as the natural competition between e-theatre and other virtual content on the internet. The author of the article offers an in-depth analysis of three different Latvian e-theatre performances, offering an overlook of the trends of digital theatre.

ABSTRACT Title: Effect Of Entomological Index And Distribution Of Dengue Hemorrhagic Fever Cases In Sukoharjo RegencyBackground: Dengue Hemorrhagic Fever (DHF) in Sukoharjo Regency has increased in cases and deaths. In 2020 there were 185 cases (IR = 20.38 per 100,000) and increased to 222 cases (IR = 24.35 per 100,000) in 2021. CFR in 2020 was 3.78% and increased to 4.95% in 2021. The highest cases were in Grogol District with 55 cases (IR = 43.12 per 100,000) with the larva-free number being 94%. This study aims to determine the effect of the entomological index on cases of DHF and the distribution of dengue cases.Method: The type of research used is observational with case-control analytic design. The study was conducted in March – April 2022 with the selection of samples carried out by purposive sampling with a total sample of 84 respondents. The variables used in this study are HI, CI, BI and larva-free number with univariate, bivariate and spatial analysis methods.Result: The results showed that the house index (p-value = 0.000), container index (p-value = 0.000), breteau index (p-value = 0.000) and larva-free numbers (p-value = 0.000) had an effect on dengue cases. The presence of larvae known through the entomological index was a sign of the presence of a larva population. High larva density indicated a high risk of dengue transmission. The spatial pattern of DHF cases in Sukoharjo Regency is a positive autocorrelation with a group pattern and the highest case density is in Grogol District.Conclusion: The entomological index that affected DHF cases in Sukoharjo Regency are the house index, container index, breteau index and larva-free numbers with a spatial pattern of distribution of DHF cases clustered.

Context Climate change is having significant impacts on species worldwide. The endangered eastern quoll (Dasyurus viverrinus) has recently undergone rapid and severe population decline, with no sign of recovery. Spatially and temporally-explicit weather modelling suggests a prolonged period of unfavourable weather conditions during 2001–03 as the proximate cause of decline. However, the mechanisms of this weather-induced decline are not currently understood. Aims The aim of this study was to investigate the hypothesis that changing weather conditions have altered the availability of key prey species, potentially contributing to the species’ decline. Methods We analysed 229 scats collected from 125 individual wild quolls across four sites between July 2011 and May 2012. Variation in dietary composition and niche breadth was compared across sites and seasons. We also compared contemporary dietary composition and niche breadth to historic dietary studies performed before the species’ decline, to identify any key changes in dietary composition over time. Key results Dietary composition and niche breadth were similar across sites but differed between seasons. Dietary niche contracted during winter (July) and early spring (September) when insect larvae formed the bulk of quoll diet, rendering the species vulnerable to weather-related fluctuations in food availability at that time. Large differences were also evident between current and historic dietary composition, with a marked shift from insect larvae to mammals, predominantly due to a reduction in corbie (Oncopera intricata) and southern armyworm (Persectania ewingii) moth larvae. Quoll abundance appears positively related to corbie larva abundance during winter, and both quoll and corbie larva abundance appear negatively related to winter rainfall. Conclusions The lower contribution of insects at sites with low quoll densities suggests that insects represent an important food item for eastern quolls during winter, when dietary niche is narrowest and energy demands are highest. Our findings suggest that weather-induced fluctuations in quoll abundance, including the significant statewide decline during 2001–03, are potentially driven by weather-induced fluctuations in corbie larva abundance. Implications Continued deterioration in climatic suitability with recent and predicted climate change could further threaten eastern quolls through reductions in the availability and stability of reliable food sources at critical life-history stages when dietary options are already limited.

AbstractFerrierite has been found at Tapu, Coromandel Peninsula, New Zealand, as a mineral vein with calcite in altered hornblende andesite lava of the Miocene Beeson's Island Volcanics. The ferrierite is low in SiO2 (63.67%) and high in Al2O3 (13.75%), MgO (3.48%), and BaO(2.35%). The large a axis and cell volume (a 19.236(4), b 14.162(6), c 7.527(3) Å, V 2050 Å3) are consistent with the low SiO2, high Al2O3, high MgO chemistry. Optical orientation and optical sign (a = Z, b = X, c = Y, 2V(-)55°) of the mineral are different from those of the Lake Kamloops ferrierite reported by Graham (1918). Refractive indices α 1.487, γ 1.489, and density 2.136 were measured. Cleavage observed on (100) is perfect and on (001) is imperfect. Using data from eighteen occurrences so far reported including the Tapu mineral, the crystal chemistry of ferrierite has been studied.

Objectives: Stresses produced during the fabrication of copings and by chewing activity can induce a tetragonal-to-monoclinic (t–m) transformation of zirconia. As a consequence, in the m-phase, the material is not able to hinder possible cracks by the favorable mechanism known as “transformation toughening”. This study aimed at evaluating if different marginal preparations of zirconia copings can cause a premature phase transformation immediately after manufacturing milling and after chewing simulation. Methods: Ninety copings using three commercial zirconia ceramics (Nobel Procera Zirconia, Nobel Biocare Management AG; Lava Classic, 3M ESPE; Lava Plus, 3M ESPE) were prepared with deep-chamfer, slight-chamfer, or feather-edge finish lines (n = 10). Specimens were tested in a chewing simulator (CS-4.4, SD Mechatronik) under cyclic occlusal loads simulating one year of clinical service. Raman spectra were acquired and analyzed for each specimen along the finish lines and at the top of each coping before and after chewing simulation, respectively. Results: Raman analysis did not show any t–m transformation both before and after chewing simulation, as the typical monoclinic bands at 181 cm−1 and 192 cm−1 were not detected in any of the tested specimens. Conclusions: After a one-year simulation of chewing activity, irrespective of preparation geometry, zirconia copings did not show any sign of t–m transformation, either in the load application areas or at the margins. Consequently, manufacturing milling even in thin thickness did not cause any structural modification of zirconia ceramics “as received by manufacturers” both before and after chewing simulation.

AbstractDespite the profound health implications of Necator americanus infection in humans, many aspects of its interaction with the host immune system are poorly understood. Here we investigated the early events at the interface of N. americanus larvae (L3) and human dendritic cells (DCs). Our data show that co-culturing DCs and the larvae trigger ex-sheathing of hookworms rapidly where a majority of DCs are sequestered onto the larval sheath allowing the ex-sheathed larvae to migrate away unchallenged. Intriguingly, DCs show negligible interaction with the ex-sheathed larvae, alluding to differences between the surface chemistry of the larva and its sheath. Furthermore, blocking of two key C-type lectin receptors on DC surface (i.e. DC-SIGN and mannose receptor) resulted in inhibition of ex-sheathing process and DC sequestration, highlighting the importance of C-type lectins on DCs in the induction of the ex-sheathing. Analyses of DC phenotype and cytokine profile after co-culture with the N. americanus larvae showed an immature phenotype as evidenced by the low expression of the maturation markers and cytokines. These data provide new insights into early events at the interface of human DCs and N. americanus larvae and could explain how L3 evade immune recognition upon initial interaction with DCs.

Dengue hemorrhagic fever is caused by dengue virus. The number of cases reported annually to World Health Organization ranged from 0,4 to1,3 million in the decade 1996–2005. The outbreak is annually happen on some provinces in Indonesia. The outbreak at 1998 and 2004 were the most cases in number. Surabaya city was an endemic area. It had suffered 640 people with 13 people were dead in 2015, which case fatality rate was 2,03%. This study aims to analyze a correlation of humidity and r ainfall with the incidence of d engue hemorrhagic fever at Gunung Anyar Primary Health Care, 2010–2016. The method of this research was time trend ecological study with the unit of analysis was per month during seven years. The results were showed that humidity correlated with dengue hemorrhagic fever (p = 0.002 and r = + 0.351). So did the r ainfall (p = 0.042 and r = + 0.230). This research was concluded that humidity and rainfall correlated significantly with the incidence of dengue hemorrhagic fever. Sign of positive meant when humidity and rainfall increased, the incidence of dengue hemorrhagic fever increased too. Climate condition at Gunung Anyar district supports to make the incidence of dengue hemorrhagic fever happen. Because of that, people should improve their attention when peak seasons are coming, like doing mosquito breeding place elimination, keeping fish of mosquito larva predators, and using repellent among daily activities.

Felsic magmatic systems represent the vast majority of volcanic activity that poses a threat to human life. The tempo and magnitude of these eruptions depends on the physical conditions under which magmas are retained within the crust. Recently the case has been made that volcanic reservoirs are rarely molten and only capable of eruption for durations as brief as 1,000 years following magma recharge. If the “cold storage” model is generally applicable, then geophysical detection of melt beneath volcanoes is likely a sign of imminent eruption. However, some arc volcanic centers have been active for tens of thousands of years and show evidence for the continual presence of melt. To address this seeming paradox, zircon geochronology and geochemistry from both the frozen lava and the cogenetic enclaves they host from the Soufrière Volcanic Center (SVC), a long-lived volcanic complex in the Lesser Antilles arc, were integrated to track the preeruptive thermal and chemical history of the magma reservoir. Our results show that the SVC reservoir was likely eruptible for periods of several tens of thousands of years or more with punctuated eruptions during these periods. These conclusions are consistent with results from other arc volcanic reservoirs and suggest that arc magmas are generally stored warm. Thus, the presence of intracrustal melt alone is insufficient as an indicator of imminent eruption, but instead represents the normal state of magma storage underneath dormant volcanoes.
