О задаче описания голоморфно однородных вещественных гиперповерхностей четырехмерных комплексных пространств
Authors: Loboda Alexandr Vasil'evich
Published: November 2020

Обсуждаются два фрагмента объемной задачи, являющейся продолжением по размерности недавно завершенных аналогичных исследований автора в пространстве $\mathbb C^3$. Один из фрагментов связан с локальным описанием несферических голоморфно однородных строго псевдовыпуклых гиперповерхностей в $\mathbb C^4$ с субмаксимальными по размерности стабилизаторами. С использованием техники нормальных форм Мозера и свойств подгрупп унитарной группы $\mathrm U(3)$ показано, что с точностью до голоморфной эквивалентности существуют всего две такие поверхности. Обе они являются естественными обобщениями известных однородных гиперповерхностей из пространства $\mathbb C^3$. Во второй части работы рассматривается техника голоморфной реализации в $\mathbb C^4$ абстрактных алгебр Ли размерности $7$, соответствующих, в частности, однородным гиперповерхностям, стабилизатор которых тривиален. Получены некоторые достаточные условия на обсуждаемые алгебры Ли, при которых орбиты всех реализаций таких алгебр являются вырожденными по Леви. Схемы изучения голоморфно однородных гиперповерхностей, позволившие получить их описания в двумерном (Э. Картан) и трехмерном (Дубров, Медведев, Ти; Фелс, Кауп; Белошапка, Коссовский; Лобода) случаях, оказываются вполне продуктивными при повышении размерности объемлющего пространства.
Голоморфные отображения вырожденных по Леви трубчатых гиперповерхностей в $\mathbb C^3$
Authors: Kruzhilin Nikolai Georgievich
Published: November 2020

Дано описание локальных биголоморфных отображений между 2-невырожденными гладкими вещественными трубчатыми гиперповерхностями в $\mathbb C^3$ с формой Леви ранга $1$. Показано, что, за исключением гиперповерхностей, локально эквивалентных границе трубы будущего, такие отображения должны быть аффинными. Доказательство использует локальный голоморфный вариант фундаментальной теоремы проективной геометрии, ранее установленный автором.

There is paucity of information in the epidemiology and pathology of tuberculosis in swine though the endemic occurrence of bovine tuberculosis was elucidated in Ethiopia. A cross-sectional study was employed to investigate the epidemiology of Mycobacterium tuberculosis complex and  Mycobacterium avium complex in swine. The study was conducted from September 2016 to December 2017 using single intradermal comparative tuberculin test, gross pathology and histopathology. Tuberculin test was carried out in farmed swine of central Ethiopia while the necropsy at Addis Ababa Abattoirs Enterprise, Ethiopia. Of the total 329 heads of swine tuberculin tested by bovine purified protein derivative antigen, an animal level prevalence of 3% (95% CI: 2-6) and a herd level prevalence of 11% (95% CI: 1-49) were observed at a cut-off value of >2mm. Multivariable logistic regression analysis revealed the protective exposure effect of body condition to tuberculin test positivity in swine (Adjusted OR: 0.06; 95% CI: 0.0-1.1; P: 0.055). Swine were predominantly in close proximity with dairy cattle which is an important risk factor for the transmission of bovine tuberculosis from cattle to swine. Necropsy study of tuberculosis-like lesions in 640 heads of swine revealed an overall lesion prevalence of 4.1 % (95 CI: 2.8-6.0). In conclusion, the present study demonstrated the occurrence of swine tuberculosis in low prevalence in farmed swine and swine slaughtered atAddis Ababa Abattoirs Enterprise in central Ethiopia. Further in-depth study covering larger sample size and wider areas is warranted so as to identify the prevalent species and their zoonotic importance.

Authors: Xu Wenguang , Luo Qiong , Wen Xiuying , Xiao Ming , Mei Qijian
Published: November 2020

Purpose: To determine the antioxidant and anti-diabetic potential of a natural flavonoid, caffeic acid in a streptozotocin-induced diabetic rat model.Methods: Experimental diabetes was induced in Wistar rats using streptozotocin injection. Caffeic acid was administered orally on daily basis for 5 weeks. A glucometer was used to monitor fasting blood glucose levels. Insulin levels were estimated using enzyme-linked immunosorbent assay (ELISA). The antioxidant potential of caffeic acid was measured by determining the activities of superoxide dismutase (SOD) and catalase (CAT), and levels of reduced glutathione (GSH) in rat liver. Standard assays were performed to determine the lipid profile of the rats. Histopathological analysis was performed to determine differences in microscopic structures of pancreas among the different treatment groups.Results: Caffeic acid administration resulted in significant enhancement of serum insulin level, and decrease in blood glucose level of diabetic rat models (p < 0.05). Caffeic acid exerted antioxidant effects by significantly increasing GSH levels and activities of CAT and SOD (p < 0.05). Histologicalexamination of the pancreas depicted normal islet morphology under caffeic acid administration in diabetic rats.Conclusion: These results reveal the antioxidant potential and anti-diabetic effect of caffeic acid in a diabetic rat model and point towards the potential applicability of caffeic acid in the management of diabetes mellitus.

Purpose: To investigate the effects of polyphenol extract from Zanthoxylum bungeanum Maxim. (ZPPC) on endocrine hormones, monoamine  oxidase activity and behavior in a mouse model of climacteric depression.Methods: Institute of Cancer Research (ICR) female albino mice (n = 50) weighing 24 – 26 g (mean wt = 25.0 ± 1.0 g) were randomly assigned to five groups of ten rats each: normal control group, negative control, and ZPPC (50 mg/kg), ZPPC (100 mg/kg) and ZPPC (200 mg/kg) groups. Depression was induced in the mice via oral administration of moclobemide at a dose of 20 mg/kg, and intraperitoneal injection of imipramine (20 mg/kg) 1 h and 30 min, before treatment. Tail suspension, forced swimming and voluntary activity tests were performed on the mice. The activity of monoamine oxidase (MAO) in mouse brain and the levels of endocrine hormones were also determined.Results: Treatment of depressed mice with ZPPC significantly and dose-dependently increased their tail suspension and immobility time (p < 0.05). The activity of monoamine oxidase in the brains of mice in the negative control group was significantly higher than that of normal control mice, but was significantly and dose-dependently reduced by ZPPC treatment (p < 0.05). Similarly, treatment of depressed mice with ZPPC significantly and dose-dependently reduced their serum adrenocorticotropin and corticosterone levels (p < 0.05).Conclusion: The results of this study indicate that ZPPC exerts antidepressant effect via suppression of brain MAO activity.

Published: November 2020

Purpose: To investigate the antimicrobial susceptibility and extended spectrum β-lactamase (ESBL) production by clinical isolates of Escherichia coli (ESBL-EC) and Klebsiella species (ESBL-KP) associated with blood stream infections (BSIs).Methods: Bacteria isolation and identification were carried out using basic bacteriological and biochemical techniques. Antimicrobial susceptibility test was performed according to the guidelines of the Clinical Laboratory Standard Institute (CLSI). Vitek 2 Compact automated system was used toconfirm the identifications (ID) and antimicrobial susceptibility test (AST). The ESBL produced by E. coli and K. pneumoniae isolates were  phenotypically characterised using Modified Double Disc Synergy Test (MDDST), as recommended by CLSI.Results: All (100 %) isolates were sensitive to imipenem and meropenem, while susceptibility to other antibiotics varied. ESBL genotypes, viz, blaTEM, blaSHV and blaCTX were encountered in the BSIs. For ESBL-EC, TEM, SHV and CTX producers accounted for 33, 16.67 and 58.3 %,  respectively, while 75, 91.7 and 100 % of ESBL-KP were TEM, SHV and CTX producers, respectively. In ESBL-KP, 67 % coexisted with all three genotypes (blaTEM, blaSHV, and blaCTX, while 8.3 % of ESBL-EC coexisted with the three encoding genes (CTX, SHV and TEM).Conclusion: ESBL E. coli and K. pneumoniae associated with BSI have been identified as TEM, SHV and CXT producers, with more ESBL-KP coexisting with all three than ESBL-EC.

Morphine pretreatment reduces myocardial ischemiareperfusion injury in heart failure rats via GSK-3β/Cx43 signaling proteins and apoptosis-related gene, Bcl-2/Bax
Authors: Zhu Xuelian , Geng Zhihai , Han Xi , Xin Xianfeng
Published: November 2020

Purpose: To investigate the effect of morphine preconditioning on myocardial ischemia reperfusion injury in heart failure rats, and the  mechanism(s) of action involvedMethods: Seventy-two healthy male Sprague-Dawley rats were assigned to 4 groups: sham, model, morphine-preconditioning and SB203580 inhibitor groups, each with 18 rats. The expressions of P-p38, p-glycogen synthetase kinase-3, and p-gap junction protein 43 in rat myocardial cells were assayed by Western blotting. The mRNA expression levels of Bcl-2 and Bax, and Bcl-2/Bax were determined using real-time fluorescence quantitative PCR.Results: The expression levels of P-p38, p-glycogen synthetase kinase-3, p-gap junction protein 43, Bcl-2 mRNA and Bcl-2/Bax were significantly higher in the pretreatment group than in the model group, while Bax mRNA was significantly lower (p < 0.05). Moreover, the mRNA expression levels of P-p38, pglycogen synthetase kinase-3, p-gap junction protein, Bcl-2, and Bcl-2/Bax in inhibitor-treated rats decreased significantly, when compared to the values for pretreatment rats; furthermore, Bax mRNA was markedly upregulated (p < 0.05).Conclusion: Morphine preconditioning significantly inhibits the expressions of GSK-3β and Cx43 signaling proteins, as well as apoptosis-related gene, Bcl-2 and Bax. In addition, it inhibits the apoptosis of rat cardiomyocytes, and reduces myocardial injury, after ischemia reperfusion, via activation of the p38 MARK signaling pathway. This provides a new strategy for clinical reduction of myocardial injury after ischemia-reperfusion.

In the 1935 the name of Persia was succeeded by Iran, and then in Revolution 1979, Iran was became Islamic Republic of Iran state (al-Jumhuria al-Islamia Iran). Ayatullah Khomeini as revolutionary leader and Syiah figure was successfully lead the Iran State to fuse between modern and al-Imam conception (Imamiyah). The paper will describe the existence of Islam in history of Iran before and after Iran Revolution in 1979. The development of Islam in Iran more related to the Syiah that dominated in population, politics, social order, and so forth. Iran population (in 2000) amount to 159.051.000 people, that 93% is Syiah, 5% Sunni, and 2% the others. It means the number of Syiah population that juridical Iran as Islamic State of Syiah. Therefore, to know about the history of Islam in Iran, we must to understand of the Syiah. In other word, the development of Islam in Iran is related to the development of Syiah in Iran, because of prescribed by the rules of qanun (legal statute of Iran) after Iran Revolution (1979) was based on mazhab Syiah, is Wilāyat al-Faqīh. However, upon Ayatullah Khomeini death, on June 3rd 1989, after Gulf War, Ali Khomeini successes to the government.

Sejarah Perkembangan Islam di Turki
Authors: Rahman Fathur
Published: November 2020

Over the hundreds of years, Islam have been growing rapidly in Turkey. Although the majority of its people are Muslims, in its development, Turkey became a republic with a secular democratic state system. In this paper will be reviewed the history of Islamic development in Turkey, including developments in the reform era that makes Turkey as it is today, the country that constructs Islam as a rational and scientific religion.The history of Turkey is divided into five periods. The first period, ie in 1299-1402, begins with the founding of the Ottoman empire. The Second Period, 1402-1566, is marked by royal restoration. The third period, 1566- 1699, was marked by the Ottoman ability to defend its territory. The fourth period, the year 1699-1838, marked degan gradually subside of the kingdom then experience more progress. The fifth period, 1839-1922, was marked by a cultural revival and Turkey became a republic, and it was no longer a system of government based on empire, dynasty, or caliphate as it had been for centuries. Mustafa Kemal established Turkey as a secular modern state based on its disappointment with the previous Caliphate system. In the latter period also called the contemporary era, although acknowledged as a secular republic, the Turkish government supports the implementation of Friday prayers in the mosque as a form of social discipline. Likewise, fasting to build patience and patience, and paying zakat encourages one's generosity, the birth of Islamic parties; moral enforcement and social justice; banning polygamy and divorce decisions must be made in court; equal rights of women and men in education, work, and in politics—in 1934 women were given the right to be nominated in national elections.
Akar Historis dan Perkembangan Islam di Inggris
Authors: Budi Syah
Published: November 2020

This paper will reveal the historical roots and Islamic development in British. The discussion covers various areas of study pertaining to historical situations. The study tends to focus on the search for the historical roots of Islam in the 7th to 15th and 16th-17th centuries, and also the development of Islamic institutions in British contemporer.The historical roots of Islam in Britain have existed since the discovery of several coins with the words 'laa ilaaha illallah' belonging to the King of Central England, Offa of Mercia, who died in 796. The history records that this Anglo Saxon King had trade ties with the peoples Muslim Spain, France and North Africa. In addition, also found in the 9th century the words 'bismillah' by Kufi Arabic on Ballycottin Cross. Indeed, in the eighth century history has noted that trade between Britain and the Muslim nations has been established. In fact, in 817 Muhammad bin Musa al-Khawarizmi wrote the book Shurat al-Ardhi (World Map) which contains a picture of a number of places in England. In the 12th century, when the feud with Pope Innocent III, King John established a relationship with Muslim rulers in North Africa. Later, in the era of Henry II, Adelard of Bath, a private teacher of the King of England who had visited Syria and Muslim Spain, translated a number of books by Arab Muslim writers into Latin. The same is done by Danel of Marley and Michael Scouts who translated Aristotle's works from Arabic. In 1386 Chaucer wrote in his book prologue Canterbury of Tales, a book that says that on the way back to Canterbury from the holy land, Palestine, a number of pilgrims visit physicists and other experts such as al-Razi, Ibn Sina and Ibnu Rusyd. At that time Ibn Sina's work, al-Qanun fi al-Tibb, had become the standard text for medical students until the seventeenth century.The development of Islam increasingly rapidly era after. In 1636 opened the Arabic language department at the University of Oxford. In addition, it is well known that the English King Charles I had collected Arabic and Persian manuscripts. In the era of Cromwell's post civil war, the Koran for the first time in 1649 was translated in English by Alexander Ross. In the nineteenth century more and more small Muslim communities, both immigrants from Africa and Asia, settled in port cities such as Cardif, South Shield (near New Castle), London and Liverpool. In the next stage, to this day, Islam in Britain has formally developed rapidly through the roles of institutions and priests, and the existence of Islam is also widely acknowledged by the kingdom, government, intellectuals, and the public at large
Perkembangan Islam di Brunei
Authors: Najtama Fikria
Published: November 2020

Brunei has existed since at least the 7th or 8th century. In the history mentioned Islam has come to Brunei since the 7th century, which at that time Brunei has become a center of trade. The king of Brunei Malay kingdom since Sultan Muhammad Shah (1383), is a Muslim sultan who leads the kingdom as well as religious leaders, and is responsible for upholding the implementation of religious teachings in the region. This paper will discuss the development of Islam and the dynamics of Malay politics, religion and traditions in Brunei Darussalam to the present, including how Brunei Islam can pass through the British colonial era with unique conditions, even as they respect Britain as the savior of their country. Brunei reached its heyday from the fifteenth to the seventeenth century at the time of the Bolkiah Sultan, who ruled the entire island of Borneo and the Philippine archipelago, before the arrival of European colonial nations. Together with Malaysia, Brunei was colonized by Britain, and since 1888 the Kingdom of Brunei is a British Commonwealth. After Malaysia Merdeka (1957), Brunei declared its independence on January 1, 1984 from Malaysia. Although not a vast country. Brunei is an Islamic state that plays an important role in maintaining Islamic values in society. This is the success of the mosque coaching program and the advancement of religious education as a top priority. The Malay Muslim Kingdom of Brunei Darussalam made Islam its national ideology to implement Sunni Islam (Ahlussunnah Waljamaah), to obey the king, and to live the life of Darussalam as a Malay nation In fact, all the activities of the kingdom and government rules serve to strengthen the existence of Islam. The threat of Islam that can disrupt the stability of the country is a radical movement. The government has banned sectarian Islamic sects such as al-Arqam and others, so that Brunei remains a Darussalam, a safe, prosperous country, and protected from disturbances and chaos.

This study aims to determine the impact of the Covid-19 pandemic on burnout experienced by nurses at Dr. Hospital. Wahidin Sudirohusodo as one of the special hospitals that treat patients affected by Covid-19. This research is a qualitative study using some literature from related articles and journals as well as the results of a discussion group forum (FGD) from nurses at Dr. Wahidin Sudirohusodo Hospital Makassar. The results showed that there was a burnout in nurses when they saw so many patients who were under observation or who were positively affected by the outbreak of this virus. Nurses are confronted with thoughts of high-risk work amid pandemic conditions and think of families who are at home as well as conditions where nurses want to go home but workloads are very high and worry about returning home in conditions carrying viruses that are invisible. Limitations of this study are the lack of access to communicate with nurses who maintain contact with researchers at the time to prevent the spread of the virus.

MODEL KAUSALITAS DAN GUNCANGAN BELANJA PEMERINTAH TERHADAP PRODUK DOMESTIK BRUTO DI INDONESIA
Authors: Sutriono Edy
Published: November 2020

This research was conducted in the first semester of 2018 aimed at determining whether there is a causal and respond relationship between government spending and GDP using data from 2005 to 2017. The method used is Granger Causality and Vector Autoregression. The results of the study state that employee spending, goods expenditure, economic and tourism functions and culture influence reciprocal GDP, while capital expenditure, social assistance, education and health functions only influence GDP. Employee spending shocks, social assistance, health functions have no significant effect and are responded to by GDP, while shocks to goods, capital, economic, education, tourism and cultural spending are very influential and are responded to by GDP. The implication for the government is in compiling the next fiscal measures and policies in allocating expenditure in the APBN to increase the role of government spending to be able to increase gross domestic product and the national economy. For the general public, as the mandate of the State Budget, it can better know the direction and impact of the State Budget on the economy.
An Inquest into the Quests and Conquests of the Radiography Profession in Nigeria
Authors: Adejo Thomas
Published: November 2020

Background: As of 1942, there were neither indigenous radiographers nor radiography training institutions in Nigeria. Presently, progress made is breathtaking. Despite the strides, there were no readily accessible records to give researchers insight on the trajectory of the profession since the beginning of the 20th century.

Objective: To trace the origin, investigate the quests, ascertain the conquests of the radiography profession in Nigeria and then document them for easy accessibility.

Methods: A prospective, longitudinal historical research spanning 6 years (2013 – 2019). Data emanated from records of the professional association (ARN), publications in the radiography profession, and interview of older radiographers, especially those who were witnesses to professional milestones. Internet search complemented retrieved information. The draft of the work was uploaded continually on radiographers’ Facebook and WhatsApp platforms for inputs. The author resolved discrepancies in the account through the weight of evidence for or against.

Results: Approximately 5,000 persons have passed through basic radiography training in Nigeria, with ≤ 5% having postgraduate qualifications. Training institutions have evolved from two monotechnics to ≥ 10 universities, with three of those are involved in postgraduate education. Radiography has witnessed considerable role extensions from traditional x-ray to more advanced practices and complex modalities. Conquests were, however, sometimes reversed, or jeopardized by internal upheavals and meddlesome interlopers.

Conclusion: Radiography in Nigeria has witnessed breathtaking evolution in training and practice from the time of World War II (WWII) until date. Radiographers themselves, with significant assistance from non-radiographers, engineered those milestones. A consolidation of intra-professional cohesion and inter-professional synergy is needful, for more focused and dedicated services to humanity.

O tema central deste artigo é o estudo histórico da relação estabelecida, nos anos de 1940 e 1970, entre a cidade de São Paulo, que se metropolizava e para isso voltava-se à construção de seu parque industrial, e das decorrências desse processo na vida de sua população, como do arrefecimento de doenças, entre elas, as doenças cardiorrespiratórias. Nesse contexto, pretende-se apontar como transformações dessa envergadura – tais como a poluição do ar emitida pelos automotivos, mas, sobretudo, pelas fábricas, dentro e fora de seus espaços de trabalho – impactaram a saúde da população trabalhadora.
Educação para as relações étnico-raciais na educação física para além da capoeira
Authors: Pomin Fabiana , Café Lucas Santos
Published: November 2020

Este artigo aborda diálogos possíveis entre a Educação Física e a diversidade étnico-racial brasileira, de acordo com as indicações legais. Esse processo se deu pela análise das ações desenvolvidas pelos professores de Educação Física da Rede Municipal de Ensino de Curitiba, em consonância com as leis 10.639/03 e 11.645/08, sobretudo, as práticas desenvolvidas em torno da capoeira, analisando se acontece a partir de uma perspectiva emancipatória ou estereotipada. Participaram 52 professores. Conclui-se que se insiste positivamente no conteúdo étnico-racial no campo da cultura corporal de movimento como condição elementar para que professores trabalhem à luz da história e da ação interdisciplinar os desafios propostos pelas citadas leis. Observou-se um aumento de ações educativas em torno a cultura e história negra, africana e indígena na graduação dos docentes; e um sólido posicionamento social, histórico e étnico-racial nas ações que se apropriam da capoeira para o tema ERER na escola.
Periodontitis and rheumatoid arthritis: three messages from published literature to clinical practice
Authors: Manzo Ciro , Kechida Melek
Published: November 2020

We read with great interest the article entitled “The re­la­tionship between periodontal status and rheumatoid arthritis – systematic review”, recently published in Reuma­tologia [1].

This relationship, suggested for more than 20 years [2], has increasingly been reported in the last years, and two recent meta-analyses confirmed a statistically significant association between rheumatoid arthritis (RA) and perio­dontitis (PD) compared to healthy controls [3, 4].

Hyperuricemia, i.e. increased serum uric acid (UA) concentration, is a common problem in clinical practice. While there are clear guidelines concerning management of symptomatic hyperuricemia in acute conditions such as gout, urolithiasis or acute urate nephropathy, less is known about their secondary prevention. Moreover, despite the ongoing debate on the role of UA in the pathogenesis of chronic kidney disease, hypertension, cardiovascular disease and heart failure, the management of asymptomatic hyperuricemia in patients with these chronic conditions is still mainly up to physicians’ judgement. Individual considerations should always be taken into account when prescribing urate-lowering therapy.

In this narrative review study, we attempt to present current trends concerning treatment of patients with either symptomatic or asymptomatic hyperuricemia in the light of the available knowledge on the role of hyperuricemia in the development of gout, renal, cardiovascular and other diseases.

Liver involvement in rheumatic diseases may occur as a primary liver disease, primary rheumatic disease with hepatic manifestations or antirheumatic drug-induced liver disease. The aim of our article is to underline the importance of monitoring and control of the level of aminotransferases and cholestatic enzymes in rheumatic disorders. Some of the rheumatic diseases with constantly elevated liver enzymes need to be investigated in consideration of concomitant primary autoimmune liver disease (such as autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis) or drug hepatotoxicity. Also, we should be aware of hepatitis B reactivation or hepatitis C flare when immunosuppressants are used.

Abstract. In this work, the detailed changes in the structure, dynamics and trace gases within the Asian summer monsoon anticyclone (ASMA) during extreme El Niño of 2015–16 is delineated by using Aura Microwave Limb Sounder (MLS) measurements, COSMIC Radio Occultation (RO) temperature, and NCEP reanalysis products. We have considered the individual months of July and August 2015 for the present study. The results show that the ASMA structure was quite different in 2015 as compared to the long-term (2005–2014) mean. In July, the spatial extension of the ASMA shows larger than the long-term mean in all the regions except over northeastern Asia, where, it exhibits a strong southward shift in its position. The ASMA splits into two and western Pacific mode is evident in August. Interestingly, the subtropical westerly jet (STJ) shifted southward from its normal position over northeastern Asia as resulted mid latitude air moved southward in 2015. Intense Rossby wave breaking events along with STJ are also found in July 2015. Due to these dynamical changes in the ASMA, pronounced changes in the ASMA tracers are noticed in 2015 compared to the long-term mean. A 30 % (20 %) decrease in carbon monoxide (water vapor) at 100 hPa is observed in July over most of the ASMA region, whereas in August the drop is strongly concentrated in the edges of the ASMA. Prominent increase of O3 (> 40 %) at 100 hPa is clearly evident within the ASMA in July, whereas in August the increase is strongly located (even at 121 hPa) over the western edges of the ASMA. Further, the temperature around the tropopause shows significant positive anomalies (~ 5 K) within the ASMA in 2015. Overall, warming of the tropopause region due to the increased O3 weakens the anticyclone and further supported the weaker ASMA in 2015 reported by previous studies.
Impact of Western Pacific Subtropical High on Ozone
Pollution over Eastern China

Abstract. Surface ozone is a major pollutant in Eastern China, especially during the summer season. The formation of surface ozone pollution highly depends on meteorological conditions as generally controlled regional circulation patterns. Here we show that summertime ozone pollution over Eastern China is distinctly modulated by the variability of West Pacific Subtropical High (WPSH), a major synoptic system that controls the summertime weather conditions of East Asia. Composite and regression analyses indicate that positive WPSH anomaly is associated with higher than normal surface ozone concentration over Northern China but lower ozone over Southern China. We show that this is mainly driven by changes in meteorological variables with stronger than normal WPSH leading to higher temperatures, stronger solar radiation at the land surface, lower relative humidity, and less precipitation in Northern China, favoring the production and accumulation of surface ozone. In contrast, all variables show reverse changes in Southern China under stronger WPSH. GEOS-Chem simulations reasonably reproduce the observed ozone changes associated with the WPSH and support the statistical analyses. Detailed contributions of different processes are quantified through budget diagnosis, which emphasizes the decisive role of chemistry. Natural emission of precursors from biogenic and soil sources accounts for ~30 % of the total surface ozone changes.

Abstract. In spring, the Mediterranean Sea, a well-stratified low-nutrient–low-chlorophyll region, receives atmospheric deposition by both desert dust from
the Sahara and airborne particles from anthropogenic sources. Such
deposition translates into a supply of new nutrients and trace metals for
the surface waters that likely impact biogeochemical cycles. However, the
relative impacts of the processes involved are still far from being assessed
in situ. After summarizing the knowledge on dust deposition and its impact
on the Mediterranean Sea biogeochemistry, we present in this context the
objectives and strategy of the PEACETIME project and cruise. Atmospheric and
marine in situ observations and process studies have been conducted in
contrasted areas encountering different atmospheric deposition context,
including a dust deposition event that our dedicated “fast-action” strategy
allowed us to catch. Process studies also include artificial dust seeding
experiments conducted on board in large tanks in three
ecoregions of the open waters of the Mediterranean Sea for the first time. This paper
summarizes the work performed at sea and the type of data acquired in the
atmosphere, at the air–sea interface and in the water column. An overview of
the results presented in papers of this special issue (and in some others
published elsewhere) is presented.

Abstract. Event-based landslide inventories are important for
analyzing the relationship between the intensity of the trigger (e.g.,
rainfall, earthquake) and the density of the landslides in a particular
area as a basis for the estimation of the landslide probability and the
conversion of susceptibility maps into hazard maps required for risk
assessment. They are also crucial for the establishment of local rainfall
thresholds that are the basis of early warning systems and for evaluating
which land use and land cover changes are related to landslide occurrence. The
completeness and accuracy of event-based landslide inventories are crucial
aspects to derive reliable results or the above types of analyses. In
this study, we generated a relatively complete landslide inventory for the
2018 monsoon landslide event in the state of Kerala, India, based on two
inventories that were generated using different methods: one based on an object-based image analysis (OBIA) and the other on field surveys of damaging
landslides. We used a collaborative mapping approach based on the visual
interpretation of pre- and post-event high-resolution satellite images (HRSIs)
available from Google Earth, adjusted the two inventories, and digitized
landslides that were missed in the two inventories. The reconstructed
landslide inventory database contains 4728 landslides consisting of 2477
landslides mapped by the OBIA method, 973 landslides mapped by field survey, 422
landslides mapped both by OBIA and field methods, and an additional 856
landslides mapped using the visual image (Google Earth) interpretation. The
dataset is available at https://doi.org/10.17026/dans-x6c-y7x2 (van Westen, 2020). Also, the location of the landslides was adjusted,
based on the image interpretation, and the initiation points were used to
evaluate the land use and land cover changes as a causal factor for the 2018
monsoon landslides. A total of 45 % of the landslides that damaged
buildings occurred due to cut-slope failures, while 34 % of those having an impact on roads were due to road cut-slope failures. The resulting landslide
inventory is made available for further studies.

Abstract. Physical scale experiments enhance our understanding of fluvial, tidal and coastal processes. However, it has proven challenging to acquire accurate and continuous data on water depth and flow velocity due to limitations of the measuring equipment and necessary simplifications during post-processing. A novel means to augment measurements is to numerically model flow over the experimental digital elevation models. We investigated to what extent the numerical hydrodynamic model Nays2D can reproduce unsteady, nonuniform shallow flow in scale experiments and under which conditions a model is preferred to measurements. To this end, we tested Nays2D for one tidal and two fluvial scale experiments and extended Nays2D to allow for flume tilting, which is necessary to steer tidal flow. The modelled water depth and flow velocity closely resembled the measured data for locations where the quality of the measured data was most reliable, and model results may be improved by applying a spatially varying roughness. The implication of the experimental data–model integration is that conducting experiments requires fewer measurements and less post-processing in a simple, affordable and labour-inexpensive manner that results in continuous spatio-temporal data of better overall quality. Also, this integration will aid experimental design.
