AbstractTrentino Porphyry is an igneous rock composed of rhyolitic–rhyodacitic ignimbrites. It belongs to the Athesian Volcanic Group, a widespread calc-alkaline magmatic association of Lower Permian age (280–270 Ma) occurring in the Trentino-Alto Adige region, north Italy. Extraction and processing are currently carried out in Trento Province, particularly in the region of Cembra Valley and its surroundings. Initially introduced for road setts throughout Trentino and Südtirol, Trentino Porphyry has progressively become one of the most important materials for paving and facing in Europe and all over the world, where it is appreciated and renowned for its durability. It has successively acquired an unquestionable versatility of application, thanks to a rare mix of mineralogy and textural and structural features, combined with excellent technical properties. Given the role played by this stone in almost any aspect of the area – cultural, architectural, production and social – it is proposed for candidacy as a Global Heritage Stone Resource.

And Function

During the 19th and 20th centuries, museums and exhibition buildings have been immensely important in the nation-building of newly born countries all over the world. By means of art and architectural representation, it was possible to bring people together in the pursuit of enduring their nationhood, to make them proud of their identity and to create a new concept of the country with a powerful historical background. Within this context, Hungary from the Compromise with Austria in 1867 up to the second decade of 20th century, and Turkey starting from the Second Constitution in 1908 until the mid-century possess proper examples of architectural production firmly connected to the identity search of both countries. This study aims to investigate the manifestations of this approach through case studies mainly from two capitals, Budapest and Ankara. While comparatively examining the chosen buildings regarding their structural features, spatial organisations, contents and function, the general architectural environment and leading actors of the era are aimed to be revealed. Additionally, the quality of the buildings themselves as display objects will be investigated.

The SARS-CoV-2 virus was first detected in Wuhan, China in December 2019 and was known to produce acute severe respiratory illness in humans which rapidly spread almost throughout the world within a few months. This human coronavirus has seven strains and they commonly produce illness in the nervous system, respiratory system and hepato- intestinal systems. This present review is an attempt to illustrate recent reports pertaining to the management of SARS-CoV-2. Further, it also highlights the diagnosis and clinical management of COVID-19. Various search engines like Scopus, Pubmed and WHO databases were accessed and literature on current advances about COVID-19 including structural features, replication, possible pathogenic, symptoms, diagnosis, prognosis, methods of prevention and possible therapeutic agents used for treatment of patients was reviewed. Current studies indicate that COVID-19 is very infectious with droplet transmission potential. The key modalities to prevent the infection is by keeping social distancing, respiratory/hand hygiene, detection of infection and subsequent quarantine of the infected persons. Presently, either no vaccine for prevention or specific treatments available, however, COVID-19 patients may be managed by using some repositioned drugs and symptomatic treatment.

Single Genus

The anchovy belongs to the same family of fishes as the herring, pilchard, and sprat, the family Clupeidæ. But whereas the herring, pilchard, and sprat have so many structural features in common that they are placed in a single genus, namely Clupea, the anchovy is in many respects so peculiar that it is placed in the distinct genus Engraulis. There are many species of Engraulis in various parts of the world, but only one on the coasts of Europe, and that one, commonly known as the ancovy, is called by zoologists Engraulis encrasicholus. The origin of these names dates back to a very early period. Both are used by ancient classical Greek authors.

SUMMARYSpecies of Marshallagia are abomasal parasites in free-ranging and domesticated ungulates in temperate climatic zones throughout the world. Pervasiveness of these nematodes is significant in various parts of the world. There has been limited research in the area of Marshallagi amarshalli pathogenesis. The aim of this study was to investigate the effects of M. marshalli on the acid secretory capacity of the abomasal mucosa and the morphological changes due to parasitic migration to different parts of abomasal tissue in sheep. Ten lambs, approximately around 6 months old, were allotted to two groups of five (A and B). The sheep from group A were infected orally with a dose of 5000 third-stage larvae (L3) of M. marshalli whereas the sheep of group B were not infected. The results indicated that the development of M. marshalli in the abomasal glands of ruminants causes pathophysiological changes, which include a reduced acidity of the abomasal contents, increased abomasal pH and increased serum pepsinogen concentrations. The reduced acid secretion is explained by a replacement of functional parietal cells by undifferentiated cells. Histology changes include mucosal cell hyperplasia, loss of parietal cells and inflammatory cell infiltration, which includes numerous granulocytes and lymphocytes.

Abstract Introduction Subspecialty policy is increasing all over the world aiming to improve the results of heavy esophageal surgeries. Aim To define the impact of having surgical specialized esophageal unit on the volume of patients and the results. Methodology We reviewed all esophageal cases managed in our esophageal specialized department (from May 2016 to May 2019 Group A) and we compared the results to previous 3 years (from May 2013 to May 2016 Group B) and to the international results. Results Esophageal surgeries performed during this period was 394 cases in group A compared to 104 cases in group B. One hundred eighty operations were performed for Gastro esophageal reflux disease (GERD) in group a (45.7%) compared to 61 cases in group B (68.7%). Forty two (10.7%) modified Heller’s cardiomyotomy (Open and laparoscopic) for achalasia were performed in group A compared to 17 cases (16.3%) in group B. Surgeries for malignant lesions were performed for 122 cases (30.9%) in group A compared to 13 cases (12.5%) in group B. Other Esophageal operations were also done for 50 cases (12.7%) in group A compared to 13 cases (12.5%) in group B. Mortalities in group A was 5 cases in benign diseases (1.8%) and 13 cases for malignant cases (10.7%) compared to 7 cases in benign diseases (7.7%) and 5 cases for malignant conditions (23%) in group B. Morbidities in group A was 46 cases in benign diseases (16.9%) and 31cases for malignant cases (25.4%) Compared to 23 cases in the benign diseases (25.2%) and 5 cases for malignant conditions (38.5%) in group B. Our results in group A are comparable to Hospital mortality rates for patients in medium-volume centers (7.5%)(1).Also we approach the International results for morbidities of benign esophageal disease (5.7 to- 12.7%) for fundoplication (2). Conclusion Having a specialized esophageal unit resulted in increase of the volume of patients and improvement of the results.

The World

The success of Barack Obama’s 2008 U.S. presidential campaign led politicians and voters all over the world to pay attention to social media. Including Donald Trump for his upcoming 2020 re-election, many politicians around the world have used social media for their political campaigns. While some social media can deliver information in various forms (i.e., video, audio, and interactive content), some popular ones, such as Twitter, are still focused mostly on plain text messaging. With political marketing using simple text messages via social media, there is a need to examine ways of creating messages that ultimately help shape voters’ perception of politicians and eventually win the election. Based on communication science, this study attempts to test the limited capacity model of motivated mediated message processing by examining whether this model can be applied to the simplest form of mediated message, which is plain text. In order to do so, structural features of text messages exchanged on social media engaged in political campaigns, namely linguistic formality and network-mediated human interactivity, are manipulated in an experiment. Findings suggest that linguistic formality and human interaction in plain text messages influence perceived friendliness, truthfulness, and dependability of the message source (politicians), as well as the receivers’ (constituents’) behavioral intent to vote for the message source in an upcoming election. This implies that politicians should pay more attention on sustainable political marketing through appropriate manipulation of structural features in social media messages.

Geosynthetic Clay Liner’s (GCLs) are an established sealing product in the geoenvironmental industry. They are used in landfill applications as caps and base liners, secondary containment for fuel storage facilities, as well as within various other containment structures such as dams, canals, rivers, and lakes. Rolled out like a carpet to provide a durable impermeable liner, Geosynthetic Clay Liners consist of a layer of high swelling sodium bentonite sandwiched between two geotextiles. Manufactured around the world in different techniques, the Canadian manufactured GCL, is mechanically bonded by needlepunching from one nonwoven geotextile through the bentonite to the other nonwoven or woven geotextile. The low hydraulic conductivity of the GCLs are used mainly as a replacement to thick, difficult to build compacted clay liners to provide a barrier to liquids and gases, offering both a technical and economical advantage. GCLs, with an average thickness of 7mm, offer a volume advantage over Compacted Clay Liners. They are more capable of withstanding freeze-thaw and wet-dry cycles; offer substantial construction cost savings in reduced on-site QC/QA and a quicker installation. Furthermore, GCLs offer equivalent or lower rates of release of fluids and chemicals than Compacted Clay Liners (CCLs). Bentonite is a clay mineral with expansive characteristics and low permeability, where montmorillonite is the chief mineral. Montmorillonite, swells when contacted with water approximately 900% by volume or 700% by weight. When hydrated under confinement, the bentonite swells to form a low permeability clay liner, the equivalent hydraulic protection of several feet of compacted clay. A relatively new engineering material for some, geosynthetic clay liners have been used extensively over the past two decades, and are finding increasing use in every sector of the environmental industry. This paper will review the technical properties of these materials, their documentation at the research level, their integrity as a sealing barrier and recent field applications in the pipeline industry. Further, because these materials are factory produced, their properties are predictable, assisting the engineer to design with a high confidence level. Technical properties and economical benefits are sure to further increase GCL installations around the world to protect our environment and more importantly our groundwater.
