Decennial geomorphic transport from archived time series digital elevation models: a cookbook for tropical and alpine environments
Authors: Lucas Antoine , Gayer Eric
Published: September 2021

On the seasonal time scale, for accessible locations
and when manpower is available, direct observations and field
survey are the most useful and standard approaches. However
very limited studies have been conducted on direct observation
at the decennial to century time-scale due to observational
constrains. Here, we present an open and reproducible pipeline
based on historical aerial images (up to 70 yrs time span)
that includes sensor calibration, dense matching and elevation
reconstruction over two areas of interest that represent pristine
examples for tropical and alpine environments. The Remparts
Canyon and Langevin River in Reunion Island, and the Bossons
glacier in the French Alps share a limited accessibility (in time
and space) that can be overcome only from remote-sensing. We
reach a metric to sub-metric resolution close to the nominal
images spatial sampling. This provides elevation time series with
a better resolution to most recent satellite images such as Pleiades
over decennial time period.

Reversible lanes in Chicago’s Kennedy Expressway are an available infrastructure that can significantly improve traffic performance; however, a special focus on congestion management is required to improve their operation. This research project aims to evaluate and improve the operation of reversible lanes in the Kennedy Expressway. The Kennedy Expressway is a nearly 18-mile-long freeway in Chicago, Illinois, that connects in the southeast to northwest direction between the West Loop and O’Hare International Airport. There are two approximately 8-mile reversible lanes in the Kennedy Expressway’s median, where I-94 merges into I-90, and there are three entrance gates in each direction of this corridor. The purpose of the reversible lanes is to help the congested direction of the Kennedy Expressway increase its traffic flow and decrease the delay in the whole corridor. Currently, experts in a control location switch the direction of the reversible lanes two to three times per day by observing real-time traffic conditions captured by a traffic surveillance camera. In general, inbound gates are opened and outbound gates are closed around midnight because morning traffic is usually heavier toward the central city neighborhoods. In contrast, evening peak-hour traffic is usually heavier toward the outbound direction, so the direction of the reversible lanes is switched from inbound to outbound around noon. This study evaluates the Kennedy Expressway’s current reversing operation. Different indices are generated for the corridor to measure the reversible lanes’ performance, and a data-driven approach is selected to find the best time to start the operation. Subsequently, real-time and offline instruction for the operation of the reversible lanes is provided through employing deep learning and statistical techniques. In addition, an offline timetable is also provided through an optimization technique. Eventually, integration of the data-driven and optimization techniques results in the best practice operation of the reversible lanes.

In the context of a society that has diversity in various aspects ranging from religion, ethnicity, ethnicity to culture, it needs deep understanding as well as awareness of the importance of multicultural education to maintain togetherness and integrity of a nation. In an effort to realize these efforts, multicullural education is interpreted as a process of understanding the diversity that exists and the similarities to be able to respect each other. In order to realize an understanding of multiculturalism, it must be endeavored in the right way, namely through education. The focus of this research is (l) what is the concept of multicultural education according to Nadirsyah Hosen? (2) how is the relevance of Nadirsyah Hosen's multicultural education concept with the aim of Islamic education?

Published: September 2021

Marriage is considered valid if it has fulfilled the terms and conditions of marriage. Among the pillars of marriage are the consent and kabul. Based on the law of origin, the ulama agreed that the consent came from the bride, while the Kabul came from the groom. However, in the matter of ittishal between the consent and the marriage contract, the scholars have different opinions. If there is no ittishal between the consent and the marriage ceremony, then the contract is still considered valid while it is still focused on the contract procession and not for a long time. The objectives of the research are, (1) knowing and analyzing the opinion of Shaykh Nizhamuddin Al-Balkhi about ittishal between consent and kabul in the marriage contract, (2) knowing the basis of the legal arguments used by Shaykh Nizhamuddin Al-Balkhi regarding ittishal between consent and kabul in the marriage contract, and (3) knowing the ijtihad method used in his istimbath al-hukminya. In this thesis research the writer uses qualitative research methods, namely research methods that produce descriptive data in the form of words or written utterances from people or observed behavior. This type of research is a research library. The results showed, 1) The law of ittishal between consent and the marriage of marriage according to Shaykh Nizhamuddin Al-Balkhi in the fatawa al-hindiyyah book that ittishal between ijab and kabul nikah is only fi majlisin wahidin. The ittishal of the marriage contract that is valid in Indonesia is regulated in the Islamic Law Compilation (KHI) in article 27: consent and kabul between the guardian and the prospective groom must be clear in sequence and not intermittent. 2) The legal basis used by Shaykh Nizhamuddin Al-Balkhi in the matter of ittishal between consent and kabul akad nikah, namely the hadith of the Prophet narrated by Abu Dawud. 3) The ijtihad method used by Shaykh Nizhamuddin Al-Balkhi is qiyas.

Problem Multikultural Pendidikan Islam
Authors: Fitriansyah Muhammad Nurul
Published: September 2021

Education is a tool in forming someone's character. An education system that only emphasizes the transfer of knowledge alone makes education no longer meaningful and has a positive effect on students. Education that does not touch the affective domain makes students less moral so that it will cause social conflict. Multicultural education is a concept of education as a solution to socio-cultural conflicts in plural societies. In the course of multicultural education began to enter the area of religious education by carrying out the mission of religious pluralism, relativism and secular humanism. In the Islamic view, the concept of multicultural education tries to deconstruct the concept of God, which should be instilled in students. Therefore, Islamic education should apply the concept that was born from the teachings of Islam itself, namely the concept of tasamuh. This research uses literature review method by searching various sources of literature that are relevant to the research subject.

Published: September 2021

Plastic pollution has become an urgent issue, since its invasion to every ecosystem has led to multiple impacts on the environment and human populations. Certain microbial strains and genera had shown the ability to biodegrade plastic sources under laboratory conditions. In this minireview, we collect and analyze scientific papers and reports of this microbial activity as we contextualize this information on the global plastic pollution problem, to provide an updated state of the art of plastic biodegradation with microbial agents. Along with a broad understanding of the general process of plastic biodegradation hosted by microorganisms. The contributions of this minireview come from the identification of research gaps, as well as proposals for new approaches. One of the main proposals focuses on coastal environments and in particular coastal wetlands as a great microbiome source with potential for plastic biodegradation, whether reported or undiscovered. Our final proposal consists of the application of this knowledge into technologic tools and strategies that have a remarkable impact on the battle against the plastic pollution problem.

Published: September 2021

Nutritional problems are issues that affect individuals or communities as a result of poor diets that lack essential nutrients. At the age of fifteen months, nearly one-third of children in developing countries are malnourished, with the majority of them being the proportion of children with height for age below standard derivations (stunting), the proportion of children with weight for height below standard derivations (wasting), and underweight. This was a quantitative study with a cross-sectional approach. This research was conducted in eight local-public health centers in the Special Region of Yogyakarta from December 2018 until February 2019. The population of this research was children under the age of seven with a total sample of 383 children. This research was analyzed using univariate and bivariate analysis. Univariate analysis was used to determine the frequency, mean value, variation, and percentage distributions, which are expressed in n and per cent. Bivariate analysis was used to determine the relationship between the independent and dependent variables. The statistical test used was a different proportion test with Chi-Square, CI (95%), and level of significance. The bivariate analysis result showed that the lack-family-support children under the age of five had a higher risk of experiencing underweight 0.04, stunting 0.28 and wasting 0.30. In addition, the children under the age of five who had a lack of family-health worker cadre partnership had a higher risk of being underweight 0.36, stunting 0.43, and wasting 0.42. In conclusion, the nutritional status of the children under the age of five (underweight, stunting, and wasting) was indirectly affected by the variable of family support and family-health worker cadre partnership.

Published: September 2021

Following the global trend, Malaysia is moving towards an aging population. With the change in age ratio, there will be more age-related diseases and challenges that need to be managed appropriately. This study aimed to determine the prevalence of successful aging (SA) among pre-retirement Malaysian public servants and the predicting factors. A cross-sectional study has been conducted using multistage sampling for selecting four out of 23 ministries and agencies under each respective ministry. Simple random sampling was used to select the state, agencies and respondents. A total respondent of 1,064 pre-retirement public servants (50-60 years old) working in nine federal government agencies within Klang Valley were finally selected. The respondents completed a self-administered questionnaire and their cognitive function was assessed using the Mini-Mental State Examination (MMSE). SA was defined as being able to fulfil all three criterions i.e. absence of six major chronic diseases and having both good physical and psycho-cognitive functions. The prevalence of SA was 37.5%. Multiple logistic regression showed that the factors with higher odds of having SA were younger age (50–54 years old) (adjusted odds ratio [aOR] 1.32, 95% confidence interval [CI] 1.01-1.73), being physically active (aOR 1.39, 95%CI 1.05 -1.84), non-obese (aOR 2.14, 95%CI 1.52-3.02) and good social support (aOR 1.78, 95%CI 1.30-2.43). A minority of public servants in this study had SA. We conclude that employers in various agencies should play roles in promoting SA aiming for healthy behaviours and providing healthy working environments.

Recently, endoplasmic reticulum aminopeptidase 1 (ERAP1) gene polymorphisms were associated with ankylosing spondylitis (AS) in genome-wide association studies (GWAS), associations which later were replicated across different populations, including the Romanian population. ERAP1 enzyme was proved to be involved in the final trimming, to the optimal length, of the antigenic peptides before loading them to human leucocyte antigen (HLA) class I molecules, different variants of ERAP1 being able to modify the types of peptides presented by HLA I molecules (including HLA-B27) to the CD8+ T cells. This article presents a detailed description of the functions, structure and the pathogenic potential of ERAP1 in AS.

Rationale. Data from controlled trials showed that adalimumab, a humanized anti-TNF monoclonal antibody, is effective and safe in the treatment of ankylosing spondylitis (AS). Objectives. The present study aimed to observe the effi cacy and safety of adalimumab in AS in a real life clinical setting. Methods. The study observed cross-sectionaly and retrospectively the efficacy and safety of adalimumab in all the patients admitted to the Rheumatology Department of “Sfânta Maria” Clinical Hospital between January 2008 and June 2013 who were classified as having AS according to the modified New York criteria. The diagnosis and follow-up of uveitic cases were done in the Ophthalmology Department of the Emergency University Hospital. Results. Within the study time-frame, 79 AS patients met the inclusion criteria: 71 (89.9%) had adalimumab for at least 24 months; 8 (10.1%) switched from adalimumab to another biological, as follows: 3 (3.8%) because of serious adverse events, 3 (3.8%) were primary non-responders and 2 (2.5%) were secondary non-responders. The clinical response was fast: after 3 months of treatment, 59 (83.1%) patients had BASDAI < 4 and 55 (77.5%) patients had BASFI < 4. Regarding safety, the serious adverse effects recorded were: infectious arthritis, pulmonary tuberculosis, pulmonary sarcoidosis. There were no cases of cancer or demyelinating disease during the study frame. Conclusions. Therapy with adalimumab in AS produces a prompt and lasting effect. The efficacy (remission) and safety (adverse events) of adalimumab can be monitored in the real-life clinical setting using BASDAI, BASFI, and routine clinical evaluations. Clinicians may need to expect a slightly higher rate of serious adverse events and rate of treatment discontinuation than those reported by controlled trials.

Aim. The study aims to assess the potential influences of rheumatoid arthritis (RA) and its specific disease measures on lean body composition phenotypes of female patients. Methods. The study was cross-sectionally designed to include Caucasian postmenopausal female RA patients and age-matched postmenopausal female controls. All the subjects gave written informed consent and the study was approved by the local ethics committee. Each subject underwent in the same day a clinical examination, laboratory tests, whole body dual X-ray absorptiometry (DXA) composition and physical activity estimation using a self-administered questionnaire. Correlations, differences and predictive power were analyzed with appropriate statistical tests. Results. The study included 107 RA patients and 104 controls. Compared to the normal subjects, who recorded higher levels of physical activity, the RA patients had significantly lower appendicular lean tissue absolute and relative indices and higher prevalence of sarcopenia. The whole body and appendicular lean tissue indices showed significant negative correlations with measures of disease severity (duration, inflammation, quality of life and radiographic progression), independent of age, levels of physical activity, body mass index and smoking. Conclusions. The measures of disease activity and severity independently predict lean tissue phenotypes in RA patients, behaving as risk factors for sarcopenia and rheumatoid cachexia. The diagnosis of RA in itself is a significant predictive factor of sarcopenia.

Background. Wnt signaling is involved in fibrosis, but the mechanisms of cross-talk with other pathways, like TGF-β, are not fully understood. (Pro)renin receptor (PRR) functions as an accessory protein to a V-ATP-ase responsible for acidic pH maintenance in intracellular compartments, and recent data indicate that PRR could be a regulator of Wnt signaling. A circulating fragment (sPRR) is generated by enzymatic cleavage of the extracellular domain and can be quantified in plasma, serum and urine. Objectives. This is a pilot study, to explore the serum concentrations of the soluble (pro)renin receptor (sPRR) in patients with systemic sclerosis (SSc). Patients and methods. Serum samples from 29 subjects with a confirmed diagnosis of SSc have been tested using an ELISA method. Clinical and laboratory parameters have been analysed for associations with sPRR serum levels. Results and conclusion. Serum levels of sPRR were higher in patients with a history of digital ulcers (p 0.041, Mann-Whitney U-test) and those with digital pitting scars (p 0.037, Mann-Whitney U-test). Serum levels of sPRR correlated with serum creatinine (r 0.424, Spearman test), in line with previously reported data. Our results indicate the need for a larger study to assess the sPRR changes in patients with SSc, including more cases with severe disease and excluding a possible impact of angiotensin-receptor blockers.
