Authors: Monteiro Patrick Romano , do Amaral Samuel Cavalcante , Siqueira Andrei Santos , Xavier Luciana Pereira , Santos Agenor Valadares
Published: July 2021

Cyanobacteria are microorganisms with photosynthetic mechanisms capable of colonizing several distinct environments worldwide. They can produce a vast spectrum of bioactive compounds with different properties, resulting in an improved adaptative capacity. Their richness in secondary metabolites is related to their unique and diverse metabolic apparatus, such as Non-Ribosomal Peptide Synthetases (NRPSs). One important class of peptides produced by the non-ribosomal pathway is anabaenopeptins. These cyclic hexapeptides demonstrated inhibitory activity towards phosphatases and proteases, which could be related to their toxicity and adaptiveness against zooplankters and crustaceans. Thus, this review aims to identify key features related to anabaenopeptins, including the diversity of their structure, occurrence, the biosynthetic steps for their production, ecological roles, and biotechnological applications.

Since its first discovery by Arnold Theiler in 1918, serum hepatitis also known as Theiler’s disease has been reported worldwide, causing idiopathic acute hepatitis and liver failure in horses. Recent studies have suggested a novel parvovirus, named equine parvovirus hepatitis (EqPV-H), to be associated with Theiler’s disease. Despite the severity and potential fatality of EqPV-H infection, little is known about the possibility of developing chronic infections and putative cross-species infection of equine sister species. In the present longitudinal study, we employed qPCR analysis, serology, and biochemical testing as well as pathology examination of liver biopsies and sequence analysis to investigate potential chronic EqPV-H infection in an isolated study cohort of in total 124 horses from Germany over five years (2013–2018). Importantly, our data suggest that EqPV-H viremia can become chronic in infected horses that do not show biochemical and pathological signs of liver disease. Phylogenetic analysis by maximum likelihood model also confirms high sequence similarity and nucleotide conservation of the multidomain nuclear phosphoprotein NS1 sequences from equine serum samples collected between 2013–2018. Moreover, by examining human, zebra, and donkey sera for the presence of EqPV-H DNA and VP1 capsid protein antibodies, we found evidence for cross-species infection in donkey, but not to human and zebra. In conclusion, this study provides proof for the occurrence of persistent EqPV-H infection in asymptomatic horses and cross-species EqPV-H detection in donkeys.

Published: July 2021

Evapotranspiration represents a significant part on the water balance and, thus, the correct evaluation of this hydrological parcel is relevant when modeling a watershed. The objective of this work is to evaluate the Soil and Water Assessment Tool (SWAT) model’s capability in adequately simulating evapotranspiration in a watershed with predominance of the Brazilian Cerrado biome. Hydrological modeling of the Gama watershed located in the Federal District, which has 57.5% of its total area covered by pristine Cerrado, was conducted. Hydrometeorological and turbulent flow variables have been monitored in weather station and Eddy Covariance (EC) tower, respectively. SWAT simulations were performed for potential evapotranspiration methods: Hargreaves (H), Priestley–Taylor (PT) and Penman–Monteith (PM). Modified versions of SWAT for estimating actual (ET) by Strauch and Volk (2013) (SV) and Arroio Junior (2016) (AR) were also tested. The calibration and verification of the SWAT model, in terms of daily flow, were carried out using a Particle Swarm Optimization algorithm, and fair results were obtained with all the methods evaluated. The actual evapotranspiration (ET) simulated with SWAT (ETsim) using the PM, PT, H, SV and AR methods for a Cerrado hydrological response unit (HRU) were evaluated and compared with the ET obtained using the turbulent flow (Eddy Covariance) method (ETobs). Comparing ETobs and ETsim results, the PM method showed the best fitness and the H and PT methods showed better fit for the dry and the rainy periods, respectively. Although representing an advance on ET modeling, the SV and AR modifications did not improve the response in terms of simulation of the studied area.
Willingness to Pay for Improved Water Supply Services Based on Asset Management: A Contingent Valuation Study in South Korea
Authors: Kim Taehyeon , Shin Jihoon , Hyung Jinseok , Kim Kibum , Koo Jayong , Cha YoonKyung
Published: July 2021

The pressure on water infrastructure has increased due to an increase in the number of aging water pipes. Aging pipes are prone to failure, causing significant financial losses and service disruptions. The increasing number of aged pipes and limited budget for pipe rehabilitation or replacement necessitates water infrastructure asset management to ensure sustainable water supply services. In this study, contingent valuation was used to estimate the willingness to pay (WTP) and value improved water supply services through the implementation of asset management. To estimate the WTP at the individual and county levels, we performed a nationwide survey including eight provinces and 24 counties/cities with distinct water supply service performances. At the individual level, the median WTP estimated using the double-bounded dichotomous choice model was 249.50 KRW/month (0.22 USD/month). The results showed that high-level satisfaction of customers with water supply services and positive price perception of water bills resulted in a high WTP. At the county level, decreasing water supply service performances were associated with a low WTP, indicating that proper interventions by local utilities are required to achieve sustainable water supply services. Our results provide a quantitative basis for decision-making in implementation of water infrastructure asset management.

State of populations and fishing of semi-anadromous fish in the North-Eastern Caspian sea
Authors: Kamelov Askarbay Kadralievich
Published: July 2021

Semi-anadromous fish (roach, bream, pike-perch, asp) are the main objects of fishing in the coastal zone of the North-Eastern part of the Caspian Sea. The state of the populations of these fish changes significantly under the influence of natural and, especially, anthropogenic factors, which have increased in recent years. The aim of this work was to study the current state of populations of semi-anadromous fish in the NorthEastern Caspian Sea. Based on the materials of three years of research (2016, 2018, 2020), with the involvement of literary sources, long-term changes in the size-weight and, age indicators, nutritional status of fish and the sex ratio in populations are considered. It has been established that the state of the semi-anadromous fish populations in the North-Eastern Caspian remains tense at the present time. All populations are characterized by general negative patterns of state change. There are tendencies of decrease in size, weight and age indicators, the number of populations and fish catches are decreasing. These changes were least of all manifested in bream (whose state is relatively stable) and were most pronounced in pike perch. The depressive state of the populations is explained by a decrease in the scale of natural reproduction in recent years, due to a decrease in the water content of the Ural River and the number of spawners allowed to spawn on the river. Marine fisheries in the North-Eastern Caspian are concentrated in shallow waters, which increases the fishing load on semi-anadromous fish and prevents their passage to spawning. It is necessary to reduce the pressure of fishing by reducing the number of nets used in the shallow water area of the North-Eastern Caspian and strict observance of the rule of the forbidden pre-estuary space of the river Ural.

Published: July 2021

Agriculture is the most important area of economic activity for the production of products and services in order to provide the population with quality food, industry with raw materials and promote sustainable development of rural areas. In recent years, there has been a downward trend in the rate of agricultural development, which is lagging behind the growth rate of the Russian economy as a whole. Structural changes in the agro-industrial complex have not produced significant positive results, which is caused by a number of reasons. One of the directions of agricultural policy in Russia is the accelerated development of animal husbandry and increasing the competitiveness of domestic livestock products in the domestic market. The state program for the development of agriculture and regulation of markets for agricultural products, raw materials and food provides for a set of measures for the priority development of animal husbandry. Implementation of these measures requires improved management in order to increase the efficiency of livestock production. The article considers aspects of the formation of accounting and analytical support for management of the livestock industry, economic and statistical analysis of trends and structural changes in the livestock industry. The best practices of Russian scientists in the field of accounting and agricultural Economics are summarized.
TRANSFORMATION IN FAMILY, LINEAGE AND VILLAGE RELATIONSHIPS OF THE HMONG PEOPLE AFTER FOLLOWING PROTESTANTISM IN THE NORTHWEST VIETNAM
Authors: Van Loi Le
Published: July 2021

Protestantism spread and developed in the Hmong community in Northwestern Vietnam has changed many aspects in the socio-cultural life of the Protestant Hmong in particular and some other ethnic minorities in the Northwest in general. Along with the rapid development of Protestantism in the Northwest, a Protestant Hmong community with a culture and lifestyle that is different from the rest of the Hmong community has been formed. Under the influence of Protestantism, family, lineage and village relationships of this Protestant Hmong community have been gradually changed in many aspects as well. This transformation has had a positive impact on the lives of the Hmong people but also poses many challenges for preserving the cultural identity of the Hmong ethnic in Northwestern Vietnam today.

Clinical judgment of GPs for the diagnosis of dementia: a diagnostic test accuracy study
Authors: Creavin Samuel Thomas , Haworth Judy , Fish Mark , Cullum Sarah , Bayer Anthony , Purdy Sarah , Ben-Shlomo Yoav
Published: July 2021

Background

GPs often report using clinical judgment to diagnose dementia.

Aim

To investigate the accuracy of GPs’ clinical judgment for the diagnosis of dementia.

Design & setting

Diagnostic test accuracy study, recruiting from 21 practices around Bristol, UK.

Method

The clinical judgment of the treating GP (index test) was based on the information immediately available at their initial consultation with a person aged ≥70 years who had cognitive symptoms. The reference standard was an assessment by a specialist clinician, based on a standardised clinical examination and made according to the 10th revision of the International Classification of Diseases (ICD-10) criteria for dementia.

Results

A total of 240 people were recruited, with a median age of 80 years (interquartile range [IQR] 75–84 years), of whom 126 (53%) were men and 132 (55%) had dementia. The median duration of symptoms was 24 months (IQR 12–36 months) and the median Addenbrooke's Cognitive Examination III (ACE-III) score was 75 (IQR 65–87). GP clinical judgment had sensitivity 56% (95% confidence interval [CI] = 47% to 65%) and specificity 89% (95% CI = 81% to 94%). Positive likelihood ratio was higher in people aged 70–79 years (6.5, 95% CI = 2.9 to 15) compared with people aged ≥80 years (3.6, 95% CI = 1.7 to 7.6), and in women (10.4, 95% CI = 3.4 to 31.7) compared with men (3.2, 95% CI = 1.7 to 6.2), whereas the negative likelihood ratio was similar in all groups.

Conclusion

A GP clinical judgment of dementia is specific, but confirmatory testing is needed to exclude dementia in symptomatic people whom GPs judge as not having dementia.
Two Important Techniques for Isolation of Microalgae
Authors: PARVIN M. , ZANNAT M.N. , HABIB M.A.B.
Published: July 2021

Microalgae (phytoplankton) plays a very important role as live food for aquatic organisms. However, out of the 80,000 species of microalgae, only 50-60 species are commercially important as live food and for other nutritional purposes. Moreover, these microalgae are available in freshwater as well as marine water which should be isolated first and then used for monoculture or production for use as live food or for other commercial purposes. There are two important cosmopolitan methods worldwide for the isolation of microalgae and then pure culture. These two methods are: Micropipette Washing Technique and Centrifuge Washing and Streak Plating Technique which are described in detail for the isolation of microalgae in the Materials and Methods section, to make these methods available to researchers. So far, there is no available published literature about a reliable, easily understandable technique for the isolation of phytoplankton and or microalgae in our library nor in our country. Researchers as well as students are having a hard time obtaining the same from their localities. Therefore, with the aim in view of producing a manual discussing these two important techniques to isolate microalgae using clear and simple language and easily available, this paper is prepared.

Published: July 2021

The dietary habits of the spotfin flathead, Grammoplites suppositus which inhabits the southeast Arabian Sea was studied. The stomach contents of 581 specimens were analysed between September 2001 and May 2002. G. suppositus preyed primarily on crustaceans. The most important preys were benthic crabs and penaeid prawns, and fishes were next in rank. During premonsoon, fishes and crustaceans were equally important, whereas in monsoon and postmonsoon benthic crabs and penaeid prawns were the predominant prey. There were significant (p165 mm) ate crustaceans such as the benthic crabs, penaeid prawns, the paste shrimp, Acetes indicus and the mantis shrimp, Oratosquilla nepa. Highest similarity in diet was observed between 216- 240 and 241-265 mm length groups. Diet breadth was higher during the monsoon season; however, the trophic level which had a mean value of 3.79 ± 0.13 peaked during the postmonsoon season. Maximum diet breadth was for 191-215 mm length groups. The length of the prey Solenocera choprai had a linear positive correlation to the predator length (r2 = 0.72). Electivity studies showed that G. suppositus has a strong preference for low trophic level animals such as benthic crabs and Solenocera choprai. The Amundsen plot showed that G. suppositus is a specialized feeder on benthic crustaceans.

Published: July 2021

Successive developmental stages of both male and female gonads and estimation of gonado-somatic index (GSI) of Puntius sarana (Hamilton 1822) were investigated over a two year period (October 2002 to September 2004). From the histological analysis, four developmental stages such as spermatogonia, spermatocytes, spermatids and spermatozoa were identified in testes. Three developmental stages of oocytes such as ogenesis (oogonia, early perinucleolus stage and late early perinucleolus stage), vitellogenesis (early vitellogenic oocytes, advanced vitellogenic oocytes and maturation stage) and atretic stage were distinguished in ovaries. Maximum mean gonad weight was recorded in June for both females (8.92±0.01 g) and males (4.48±0.21 g). The testes at early development stages between October and March contained mostly spermatogonia, spermatocytes and spermatids, although a small amount of spermatozoa was also found in late March. The mature testes began to develop in early April and were prominent from May to September. Highest percentage of oogonia in the ovary was recorded in the month of November; while the highest percentages of early perinucleolus stage and late perinucleolus stage were recorded in the month of January. Vitellogenesis (matured oocytes) occupied the most areas of the ovaries which were observed from May to mid September but was prominent in June. All oocytes did not mature at the same time. Only the matured oocytes ovulated in the spawning period while immature oocytes gained maturation under way of vitellogenesis and released at the second spawning time in the months of August and September.

Authors: NABI N. , AHMAD R. , HASNAIN A.
Published: July 2021

Partial biochemical characterization of highly purified homozygous serotransferrin (Tf) phenotypes AA, BB and CC of air-breathing murrel, Channa punctata, was conducted. Molecular weight of each pure Tf variant was 75 kDa. Each Tf variant also had sialic acid as carbohydrate moiety of 10.5 kDa. Difference in spectra of ironapotransferrin complexes of C. punctata and human Tf were similar. Complex of each apoTf with iron had its maximum at 460 nm. Lack of a shoulder at 480 nm was characteristic of TfBB, while TfCC and TfAA had one shoulder at 480 nm and the other at 510 nm. The TfBB also had the highest total iron-binding capacity followed by TfCC and TfAA, respectively, though total saturation for each Tf was reached at 14 μM FENTA. Interestingly, the relative total iron-binding capacities of TfBB and CC showed a positive correlation with the allelic composition of populations, which were the sources of sera. The significance of iron binding capacities of Tf variants along with some other factors on the population structure of C. punctata is discussed.
Desenvolvimento comunitário e participação: organização de consenso e hegemonia burguesa no Brasil
Authors: Soares Baima Larissa , Souza Lobo Guzzo Raquel
Published: July 2021

Este texto busca realizar uma avaliação teórica da possível funcionalidade de um modelo de trabalho comunitário em Psicologia para a construção de uma forma passiva de consenso dentro do conjunto de transformações ocorridas no Brasil durante os recentes governos do Partido dos Trabalhadores. Esse modelo é o do desenvolvimento comunitário, e o objeto da avaliação é a concepção de participação dele apreendida, abordada a partir das contribuições teóricas de Gramsci (1891-1937) sobre o Estado e sobre a noção de revolução passiva. Analisada a partir dessas chaves conceituais, tal concepção de participação parece não romper, em seus fundamentos, com a concepção de participação dos modelos aos quais o desenvolvimento comunitário se propõe como alternativa.

Професіоналізм у сфері публічного управління у контексті цілей вищої освіти
Authors: Rybkina Svitlana
Published: July 2021

У статті розглядаються проблеми цілепокладання освітнього процесу у вищих навчальних закладах у контексті формування професіоналізму фахівців у царині публічного управління.
Визначено, що на сьогодні існує системна невідповідність рівня професіоналізму спеціалістів у сфері публічного управління, яка має своїм прямим витоком відсутність адекватної професійної підготовки, яку мають забезпечити вищі заклади освіти. Усунення цієї невідповідності бачиться насамперед на шляхах визначення цілей вищої освіти під час підготовки фахівців для потреб публічного управління. Показано, що управлінський професіоналізм є багатоаспектним явищем і пов’язаний з безперервним навчанням, практикою професійної діяльності та особистісним самовдосконаленням. Вищі навчальні заклади формують цілісний освітній простір, у якому відбувається становлення та розвиток публічного управлінця як професіонала. Саме у цьому просторі відбуваються основні складові процесу професіоналізації - підготовка, перепідготовка, спеціалізація та підвищення кваліфікації публічних управлінців. Публічно-управлінська компетентність є дуже ємним та різностороннім поняттям, оскільки охоплює практично всі здатності, які потрібні професіоналу-управлінцю для успішного функціонування у публічній сфері. Стосовно діяльності закладів вищої освіти, компетентність майбутнього фахівця у царині публічного управління означає насамперед здатність адекватно застосовувати отримані у процесі навчання знання, вміння і навички для ефективного виконання власних професійних функцій. Саме професійна компетентність має вважатися основною метою підготовки публічних управлінців у закладах вищої освіти, оскільки вона відображає готовність випускника забезпечувати результативність виконання професійних обов'язків. Що ж стосується професіоналізму, то він представляє собою синтез професійної компетентності та індивідуального практичного досвіду публічного управлінця.
Система зв’язків з громадськістю в органах публічного управління (на прикладі органів правосуддя)
Authors: Torkhova Nadiia
Published: July 2021

У статті охарактеризовано зв’язки з громадськістю (паблік рілейшнз) як систему взаємопов’язаних елементів, яка є складовою частиною стратегічного менеджменту в органі публічного управління. Проаналізовано особливості найбільш значущих елементів системи паблік рілейшнз та їхньої ролі у процесі організації діалогічних відносин органів публічного управління з громадськістю. Особливу увагу приділено аналізу понять «громадськість», «громадська думка», «інструменти зв’язків з громадськістю та ЗМІ». На прикладі органів правосуддя розглянуто застосування окремих прямих інструментів зв’язків з громадськістю (програм охоплення). Визначено, що однією із фундаментальних засад управління зв’язками з громадськістю є участь органу публічного управління у житті громади, яку можна забезпечити з допомогою програм охоплення, структурованих відповідно до певних категорій громадян та їхніх потреб. Автор визначає властивість програм охоплення для формування відносин органу публічного управління з громадськістю у векторі партнерства. У статті охарактеризовано прямі зв’язки з громадськістю як нову інтерактивну модель комунікації, що має актуалізувати комунікативний аспект та максимально наблизити органи влади до суспільства. Наголошено, що реалізація прямих ініціатив забезпечує формування позитивного іміджу органів державної влади, сприяє просвітницькій діяльності й вихованню правової культури, позитивно впливає на правильне сприйняття громадянами функцій органів публічного управління. У статті визначено важливість складання «профілю» (характеристики) цінностей кожної із груп цільової аудиторії, який включає у себе комплекс ознак – опорних пунктів у процесі стратегічного планування комунікативної діяльності установи. Автор обґрунтовує, що першим кроком до актуалізації програм охоплення має стати закріплення їх у комунікативних стратегіях та планах комунікативних заходів органів публічного управління. При цьому слід ураховувати постійний розвиток і зміну медіапростору та зважати на те, що традиційні методи комунікації мають слабкий вплив на молоде покоління.
Using Grounded Theory to Investigate Evidence Use by Course Leaders in Small-Specialist UK HEIs
Authors: van Veggel Nieky
Published: July 2021

The study of evidence-based course leadership in higher education focusses on twodifferent areas of practice: higher education course leadership, and evidence-basedpractice. Course leadership is an understudied area of research, with few publicationsdiscussing the role of the course leader in higher education. Although evidence-basedpractice is an area of ever evolving research in many disciplines, there is a distinct lackof research on whether course leaders in higher education apply evidence-based practicemethods in their professional practice. This lack of a pre-existing theory points theresearcher towards classic grounded theory to investigate and generate a new theory oncourse leaders’ experiences. Since leadership, and therefore course leadership, is aninherent complex social process, selection of classic grounded theory as a researchmethodology seems a logical choice. Classic grounded theory has been successfullyused to investigate phenomena in education and in evidence-based practice. Groundedtheory therefore is an appropriate selection for research in education and highereducation settings for areas of research where no theory currently exists. Moreover,grounded theories regarding experiences and perceptions of evidence-based practicehave been published in various contexts demonstrating that it is an appropriate methodfor investigating course leaders’ experiences with evidence-based practice.

Published: July 2021

The COVID-19 (SARS-CoV-2) pandemic brought in-person teaching to an abrupt halt in March 2020 posing the problem of how to continue to deliver undergraduate courses remotely. This paper presents a detailed case study of three international online Higher Education (HE) teaching networks which formed to address the critical need to support laboratory teaching in the UK and Australia. The study employed a sequential mixed methods design using an online survey followed by structured discussions with network leads. The findings show these networks provided a space for knowledge development, built confidence, supported collaboration, and reduced isolation of members. Multiple factors contributed to their success: COVID-19 created a common purpose; individuals prioritised engagement; and both participants and their contributions were welcomed. The research found that the three networks fit the framework for Professional Learning Networks (PLN) and provide a useful template for a Higher Education PLN operating anywhere in the world.
A Workforce and Truck Allocation Model in a Solid Waste Management System: A Case from Nigeria
Authors: Ighravwe Desmond E. , Oke Sunday A.
Published: July 2021

The management of waste with the limited workforce and trucks is a complicated problem. Currently, there is insufficient evidence in literature on how this process could be optimised. In this article, two new models on genetic algorithm and differential evolution were developed to jointly optimise the cost and human reliability of a municipal solid waste (MSW). It optimised this system’s benefit-cost and established the relationship between a MSW’s workforce and truck allocation. Although prior research has revealed relationships among cost, workforce strength, and truck allocation activities, however, the nature of this relationship and the unique attribute of workers’ reliability to influence the total operating cost and the benefit-cost ratio have not been thoroughly understood. A case study of a MSW agency in Nigeria was used to demonstrate the applicability of the proposed model. The results obtained showed preference to the differential evolution algorithm’s results. This article contributes to MSW in the following ways: it presents a model to assign reliability to workforce in a MSW system based on evolutionary algorithms performance, and it optimises a MSW system’s total operating cost and the benefit-cost ratio concurrently.
Biochar from Rice Husk as Efficient Biosorbent for Procion Red Removal from Aqueous Systems
Authors: Palapa Neza R. , Taher Tarmizi , Juleanti Novie , Normah Normah , Lesbani Aldes
Published: July 2021

Numerous reports have elucidated the use of biochar (BC) to adsorb dyes from wastewater. However, its applicability for adsorbing Procion Red, which causes carcinogenic and mutagenic effects on aquatic life, has not been studied. In this work, biochar produced from rice husk in Sumatera, Indonesia was used as a biosorbent for Procion Red removal from aqueous systems. Rice husk-BC was characterised using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, surface area specific analysis, and scanning electron microscopy (SEM) for mor-phological analysis. The characterisation showed a (002) reflection peak at 2θ = 23° with broad and quite intense diffraction, which indicates reflection of electromagnetic waves by silicates, oxides and carbon present in the rice husk-BC. The surface area and SEM morphologies confirm that after pyrolysis, the surface of the rice husk changed. The FTIR spectra confirm the presence of functional groups such as the carboxylic acids and aromatic compounds. The surface area of rice husk-BC was up to ten times that of its raw material. The results of adsorption studies indicate that adsorption of Procion Red on rice husk-BC follows a pseudo-second-order (PSO) reaction with a rate constant of 0.044 min-1 and Langmuir isotherm models with a coefficient of correlation close to unity. The maximum adsorption capacity increased from 36.900 mg g-1 for the rice husk to 84.034 for the rice husk-BC. Thermodynamic analysis showed positive enthalpy and entropy, indicating that Procion Red adsorption is endothermic; thus, the Gibbs energy values decreased with increase in temperature, indicating that high temperatures are favourable for the adsorption process. Furthermore, the study of adsorption of Procion Red on rice husk-BC and regeneration of the adsorption capacity of rice husk-BC showed the largest drop in the fourth and last cycle.

In most countries of the modern world, the problem of overcoming poverty is hanging like a sword of Damocles. The rich and poor exist from the very beginning of the mankind,
having the open and hidden opposition towards each other. Namely, this can be named, one of the main reasons of outbreaks of revolutions in different countries, followed by
the destruction and victims.
Even the modern civilized world has not been able to solve this universal challenge, in spite of all the scientific and technological achievements. For Poverty alleviation all the States need to carry out the right and rational social and economic policy. Simultaneously, it is necessary to find ways to balance the uneven distribution
of the World wealth, overcome the cultural barriers, and the most important thing is to undertake more effective measures for inclusive development of economics of the developing and backward countries.

Published: July 2021

Acute mesenteric ischemia (AMI) occuring due to sudden, partial or complete interruption of blood ow in main visceral arteries of the abdomen
eventually resulting in intestinal ischemia and/or bowel gangrene is a surgical emergency. It represents 0.1% of hospital admissions and 2% of the
revascularization operations for atheromatous lesions. 50% of AMI is caused by embolic phenomenon, 25% by thrombotic episode and rest 25%
by both. The most common vessel involved in AMI is superior mesenteric artery. Acute mesenteric embolic ischemia (AMEI) arises typically from
a cardiac emboli in patients with atrial brillation or following MI. Patients usually presents with central abdominal pain, out of proportion to the
physical ndings initially, later becoming diffuse associated with bloody diarrhoea during the episode. An early diagnosis, an aggressive
resuscitation, intravascular or surgical restoration of blood ow and subsequent bowel resection based on bowel viability helps reduce morbidity
and mortality.

There is a growing awareness that humanity and the Planet Earth are near to a tipping point, since we are experiencing a critical transition phase, resulting from a hyper-connected world, where global interactive structures and cumulative feedback evolve. It follows an increasing systemic complexity at all levels, hence uncertainty and instability all decision makers have to deal with. New strategic and operational frameworks are therefore needed. The book aims to provide a theoretical-strategic frame and to suggest he book aims to provide a strategic-operational frame and to suggest both an operational architecture and mechanisms suitable for assessing the effectiveness of strategic choices.
Learning from COVID-19: The Role of Architecture in the Experience of Urban Landscapes
Authors: Rodríguez Iturriaga Marta
Published: July 2021

The COVID-19 pandemic, with its lockdowns and mobility restrictions, has created an atmosphere of global reflection towards contemporary urban landscapes. Architecture is an essential component in them and determines, to a large extent, how building users perceive, interpret, and value the surrounding environment. From an experiential and phenomenological perspective, and taking into account the situations lived in 2020, the paper invites to examine the existing relations between architecture and urban landscape at three levels: first, the experience of the environment from the architectural space —namely, the home—; second, the experience of the “interior urban landscape” at street level; and finally, the experience of the “exterior urban landscape” from the city fringe or vantage points that provide vast prospects. The article advocates a holistic understanding of landscapes from the architectural and planning practice and proposes this integrating issue as the guiding axis of new urban policies.
Urban Landscape and Horror Vacui, spectacularity of a distorted perception
Authors: Verdiani Giorgio , Giraudeau Stéphane
Published: July 2021

In this paper, the very original urban landscape perception caused by the emergency after the 2020’ New CoronaVirus Pandemic event will be discussed and analyzed. Most of the approaches conducted on social media and on the newspaper have pointed to putting in evidence the spectacular empty cities “as never seen before”, which thing is absolutely correct and underlines a unique condition otherwise almost impossible to experience. In fact, the total lock-down caused by the emergency made it impossible to move from a view of the urban landscape to another, where most of the people were able to see such an emptiness only for their own town, maybe just for their own neighbourhood and maybe just from some lucky windows. The global condition will be watched only composing together the pictures exhibited online and in the newspaper. But … … … A specific set of images, created in the days of the emergency will comment and describe the content of the paper.
