Kinerja Campuran Beton Aspal AC-WC dengan Penambahan Limbah Botol Plastik
Authors: Iskandar A. Cempana Sari
Published: June 2023

Salah satu syarat dari lapis perkerasan jalan adalah mampu memikul beban yang bekerja tanpa terjadi deformasi yang berarti. Namun sebaliknya, terjadi pengurangan umur layanan konstruksi perkerasan jalan di beberapa jalan yang ada di Indonesia, seperti ruas Jalan Hasanudin – Yos Sudarso mengalami pengurangan masa layan sebesar 3,162 tahun atau 31,620% dari umur rencana jalan 10 tahun menjadi 6,838 tahun dan Jalan Diponegoro, Cilacap, Jawa Tengah terjadi penurunan umur layanan jalan sebesar 4,453 tahun atau 22,26% dari umur rencananya. Untuk mengatasi masalah tersebut, limbah botol plastik ditambahkan ke dalam agregat campuran aspal panas sehingga dapat menambah kinerja campuran. Teknik pencampuran ini dikenal dengan cara kering. Tujuan penelitian ini yaitu untuk menganalisis kinerja campuran beraspal jenis AC-WC dengan memanfaatkan limbah botol plastik sebagai bahan tambah. Pengambilan data dilakukan dengan pengujian laboratorium berdasarkan Spesifikasi Umum Pekerjaan Jalan oleh Bina Marga dan metode pengujian menggunakan Metode Marshall. Di dalam penelitian ini, variasi kadar limbah plastik yang dimasukkan dalam campuran, yaitu sebesar 0 - 2,5% dari berat agregat dan variasi kadar aspal, yaitu sebesar 5,5–7,5% dari berat agregat. Dari variabel tersebut maka dibuat 90 sampel uji. Hasil penelitian memperlihatkan bahwa penambahan limbah botol plastik meningkatkan kinerja campuran beraspal jenis AC-WC.

Published: June 2023

Abstract— Biometric information systems have been widely used in the fields of government, shopping centers, education and even security, which offer biological authentication so that the system can recognize its users more quickly. The parts of the human body are identified by a biometric system that has unique and specific characteristics, one of which is the face. Adjustment of facial image deals with objects that are never the same, due to the parts that can change. These changes are caused by facial expressions, light intensity, shooting angle, or changes in facial accessories. With this, the same object with several differences must be recognized as the same object. In this study, the data used were 388 face images and the sata test consisted of 30 face images. Before the face is tested, preprocessing and feature extraction are carried out using the Haar Cascade Classifier and then detected using Eigenface and Fisherface. Based on the research results, the Fisherface method is an algorithm that is accurate and efficient compared to the Eigenface algorithm. The Fisherface algorithm has an accuracy of 88%. while the Eigenface method has an accuracy rate of 76%.

Infection with swim bladder nematode Anguillicola crassus in relation to European eel growth, age, and habitat along the German Baltic coast
Authors: Simon J , Ubl C , Lewin WC , Dorow M
Published: June 2023

One possible reason for the European eel (Anguilla anguilla) population decline is the neozoan eel swim bladder nematode Anguillicola crassus. To investigate whether the prevalence of A. crassus and the associated swim bladder pathology is related to eel habitat, growth rate, and age, 728 yellow eels from 6 habitats differing in salinity and located along the German Baltic coast were examined between 2005 and 2009. The prevalence of A. crassus varied between habitats, ranging from 9 to 57%. Infection prevalence and the percentage of eels with a damaged swim bladder were significantly higher in inner coastal waters compared to more saline open coastal water. In infected eels, 1 to 32 adult and preadult individuals of A. crassus were observed. The mean infection intensity varied between habitats from 2 to 7 nematodes per eel but did not significantly differ between inner and open coastal waters. Infection prevalence and intensity decreased significantly with age when all open coastal waters and all habitats were combined. Both the lower prevalence of A. crassus and the swim bladder damage of older eels and of eels originating from open coastal water habitats suggest that these eels have a higher fitness for spawning migrations than eels from inner coastal waters. The present study underlines the importance of eel screening on a sufficiently small geographical scale for the accurate estimation of eel recruitment and the identification of priority areas that are likely to produce healthy silver eels.

Diabetes mellitus proved to be a significant risk factor for both COVID-19 infection and poor outcomes among these chronic health problems. Plants are a rich source of chemical components that could block carbohydrate digestion enzymes, and they can be utilized as therapeutic or functional foods. Natural pigments that have potential benefits, such as chlorophyll, anthocyanin as a part of flavonoid, and carotenoid. Chlorophylls are the most significant and widespread pigment molecules in nature, and they are required for photosynthesis to occur. Anthocyanins are the most important group of water-soluble pigments in plants, responsible for the red, purple, and blue colors of many fruits, vegetables, cereal grains, and flowers. Carotenoids, natural pigments found in an array of different foodstuffs, are the most abundant pigments present in the human diet.

Distal Biceps Tendon Reconstruction with Achilles Tendon Allograft: A Case-Series
Authors: M Ford Kory , A Buckwalter V Joseph , Garcia Fleury Ignacio
Published: June 2023

Background: Chronic, complete ruptures of the distal biceps tendon are often difficult to surgically repair due to significant fibrosis and retraction. The use of a graft is recommended, with recent literature suggesting that an Achilles tendon allograft leads to superior clinical outcomes. The purpose of this study is to present the surgical technique and retrospectively review the clinical outcomes of a distal biceps reconstruction technique that utilizes an Achilles tendon allograft with an Endobutton bicortical fixation system through a single S-shaped incision. Methods: Seven male patients and eight cases of distal biceps reconstruction with Achilles tendon allograft were identified between January 2017 and March 2022. The mean age was 48.3 ± 8.9 years with a mean time from initial injury to surgery of 6.1 ± 3.8 months. Charts were retrospectively reviewed for patient demographics, procedural technique, preoperative and postoperative evaluation, and complications. Results: The cohort had a mean follow-up of 4.6 ± 2.0 months (range, 1.4-8.2). At the final office visit, full range of motion had returned for all patients except one, who had a persistent 10° extension deficit. Flexion strength had returned to equal preoperative and preinjury gross strength out of 5 (4.7 ± 0.5 preoperatively vs. 4.4 ± 0.5 postoperatively) and supination improved from preoperative strength (2.2 ± 1.1 preoperatively vs. 3.6 ± 1.2 postoperatively). Four out of eight cases resulted in a new neuropraxia identified in postoperative care: two lateral antebrachial cutaneous nerves, one superficial branch of radial nerve, and one ulnar nerve, with insufficient follow-up duration to determine resolution. One patient reported excessive scar formation; otherwise, there were no major complications. Conclusion: Reconstruction of the distal biceps tendon using an Achilles tendon allograft is a technically challenging, yet effective approach for the treatment of complete distal biceps tendon ruptures that are chronic in nature, resulting in an improvement in preoperative disability with few postoperative complications.
Sustainable Development and Cultural Policy: Do They Make A Happy Marriage?
Authors: Géraldine Dallaire , Colbert François
Published: June 2023

The aim of this article is to foster debate within the academic community on the notion of culture as the fourth pillar of sustainable development. Is Agenda 21 for Culture not just another way of making the case for increased funding of the arts by the different governments? Are the goals of this fourth pillar not the same as those traditionally found in cultural policies? This article looks at the origins of Agenda 21 and raises questions about its relationship with the challenges facing cultural and arts organizations, the different definitions of the term “culture,” and the distinction between high and popular culture. It explores the links between these questions and the economic and market issues confronting stakeholders in the cultural sector as well as public policy-makers.
Opportunities and Critical Points for the Introduction of Performance Measurement Systems in Theatres. A Comparison between Theoretical Assumptions and Empirical Realities
Authors: Samuk Sahizer
Published: June 2023

In recent years, cultural organisations have introduced and tested new management tools to achieve their institutional goals. The “Value for Money Approach” has played a relevant role in influencing these changes for non-profit cultural organisations. This paper specifically considers one kind of management tool: performance measurement (PM) systems. Their goal is to give to the management quantitative and qualitative information that can guide strategic choices in the long-term. We will analyze the possibilities of application of a good PM system in cultural organisations, with particular focus on theatres. More precisely, the aim of this work is to verify and discuss opportunities and critical points implied by the introduction of a PM system in theatres. Our research starts with an analysis of the theoretical framework of PM systems and theatre management. The theoretical approach is supported by the reference to a specific case study analysed in this paper, the Municipal Theatre of Ferrara (Italy), and to other case studies provided by the literature in arts and cultural management.

At the same time, however, public officials affirm that the arts, culture and, more broadly, the creative industries, constitute one of the most reliable means available to contemporary developed societies to overcome the crisis.

How can such a paradox be understood? Are public authorities schizophrenic? Is there a contradiction in the definition and the implementation of public policies? Conversely, can one hypothesize that public action has a logical underpinning? What would be its basis?

The answer may be identified on two levels: on the one hand, there is an increasing instrumentalisation of artistic and cultural activities, which are used for ends which are at least partly foreign to them (in particular, to economic and diplomatic ends). On the other hand, a reorientation of public policies concerning the creative and cultural industries is occurring. It would seem that it is in this sense that the engagement of a growing number of CEOs and leaders in favor of the cultural industries may be understood.

This policy choice, even if it appears to offer certain strategic opportunities to the artistic and cultural sector, seems nevertheless to involve serious risks for cultural creation, artistic experimentation and “scientific” activities undertaken by museums. Furthermore, it risks accentuating the trend of concentrating public and private funds on the most prominent museums and historical sites, thereby threatening to accentuate the implementation of a two-tier system in France, as well as in the UK.
Fostering the creation of cross-sectorial networks: key drivers for culture-related collaborations in Italy’s Po Delta Region
Authors: Borin Elena
Published: June 2023

This article investigates the implications and potential of implementing cross-sectorial networks related to culture by means of empirical research in the Po River Delta area of Northern Italy. The aim of the research is to provide insights into the main difficulties that may arise and action that could be taken to implement successful collaborations between subjects belonging to different sectors. The investigation provides useful information for cultural players and at the same time contributes to the academic debate on the possibility of rethinking the current governance systems and management models in the cultural sector in favour of participatory approaches involving multiple stakeholders, citizens and communities on the basis of shared cultural identity and common goals and objectives.
Conservation of cultural heritage: from participation to collaboration
Authors: Spiridon Petronela , Sandu Ion
Published: June 2023

The concept of participatory conservation of cultural heritage involves the investigation of ways in which community members can be encouraged to become active actors and collaborators in the preservation/restoration process of cultural heritage assets and, beyond that, promoters of tourism policies and processes and the cultural, ethnographic and religious values that such assets embody. This paper aims to present some forms of participation in the conservation of the cultural heritage process as an important part of integrated scientific conservation management, starting from an important series of documents on international policy in the field.
More is better!Current issues and challenges for museum audience development: A literature review
Authors: Cerquetti Mara
Published: June 2023

The purpose of this conceptual paper is to investigate how research on museum management has been approaching audience development and community engagement in our society – especially in Europe, where the development of democratic participation is proclaimed as a shared commitment. This literature review endeavours to grasp both the state of the art in museum audience research and audience development and the most relevant issues emerging in the scientific debate on this topic in the last 20 years (1995-2015). After analysing the main challenges concerning the innovation of the museum sector, the paper discusses the gaps in visitor studies and museum communication, making suggestions for future research and practice. In the field of museum marketing, this review tries to build a theoretical framework linking changes in audiences, museum role, visitor studies and strategies for visitor involvement, to support cultural institutions in achieving their mission and maximizing value creation.

Published: June 2023

Cultural heritage is a complex and interconnected ecosystem requiring innovative methods and techniques to facilitate its management and valorization. From these assumptions, our research proposes a new, integrated and networked approach based on a three-level case study belonging to the archaeological context. In detail, the approach defines the lifecycle of an archaeological site, its processes and network analysis. It does this through the use of Business Process Management (BPM) and Social Network Analysis (SNA) techniques, taking the work of archaeologists at the Archeologia Ricerca e Valorizzazione s.r.l. (A.R.V.a) as a case study. The main objective of the approach is to provide valuable insights to optimize the flow of data, gather information and share knowledge created during the archaeological process, starting from lifecycle management and carrying on with the processes modelling and identification of roles and relationships among different stakeholders. The final aim is to improve the sustainable valorization of an archaeological site, facilitating value creation, strengthening the connections between culture and local development, and enabling a participatory governance of archeological heritage.

Familial chylomicronemia syndrome (FCS) is a rare autosomal recessive metabolic disorder that causes extremely elevated plasma triglyceride levels, with limited therapeutic options. Volanesorsen is an antisense oligonucleotide approved for its treatment. A 24-year-old woman with genetically diagnosed FCS secondary to a pathogenic variant in APOA5 and a history of recurrent hypertriglyceridemia-induced pancreatitis episodes was being treated with volanesorsen, 285 mg every 2 weeks. Treatment with volanesorsen achieved normalization of triglycerides to <200 mg/dl. However, after the fifth dose of the medication, the patient developed urticaria and volanesorsen was discontinued. In the absence of alternative pharmacological treatments, the patient received a novel desensitization protocol for volanesorsen that allowed continuation of therapy, without evidence of hypersensitivity reactions after subsequent administrations. FCS requires aggressive multimodal therapy and close follow-up. Volanesorsen has shown great efficacy, but a significant rate of discontinuation due to side effects has been observed. Here, the patient presented an immediate hypersensitivity reaction to volanesorsen, but the provision of a desensitization protocol was effective, facilitating continued treatment and impacting the survival and quality of life of the patient.
Pancreatic Cancer Progression Is Regulated by IPO7/p53/LncRNA MALAT1/MiR-129-5p Positive Feedback Loop

Published: June 2023

Background: Pancreatic cancer is a malignancy with poor prognosis. Importin 7 (IPO7) is a soluble nuclear transport factor, which has been linked to the pathogenesis of several human diseases. However, its role and underlying mechanism in pancreatic cancer are still obscure.

Methods: Immunohistochemical staining and quantitative real-time polymerase chain reaction (qPCR) were performed to determine IPO7 expression in pancreatic cancer tissues and adjacent tissues. Western blot was used to measure IPO7 expression at the protein level in cell lines. Cell Counting Kit-8 (CCK-8), 5-bromo-2′-deoxyuridine (BrdU), flow cytometry, and Transwell assays were employed to explore the biological functions of IPO7. Subcutaneous xenograft transplanted tumor model and caudal vein injection model in mice were also established to validate the oncogenic role of IPO7. Western blot and qPCR were utilized to detect the regulatory function of IPO7 on p53 and metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), respectively. Interaction between MALAT1 and miR-129-5p and interaction between miR-129-5p and IPO7 were verified by bioinformatics prediction, qPCR, dual-luciferase reporter gene experiment, RNA immunoprecipitation (RIP), and pull-down assay.

Results: Upregulation of IPO7 in pancreatic cancer tissues was associated with adverse prognosis of the patients with pancreatic cancer. Knocking down IPO7 remarkably suppressed cancer cell proliferation and metastasis, while it promoted apoptosis. Overexpression of IPO7 facilitated the malignant phenotypes of pancreatic cancer cells. Mechanistically, IPO7 could repress the expression of p53 and induce the expression of MALAT1 but reduce miR-129-5p expression. Furthermore, miR-129-5p was identified as a posttranscriptional regulator for IPO7, and its inhibition led to IPO7 overexpression in pancreatic cancer cells.

Conclusion: IPO7 is a novel oncogene for pancreatic cancer, and IPO7/p53/MALAT1/miR-129-5p positive feedback loop facilitates the progression of this deadly disease.
Synthesis of chiral malonates by α-alkylation of 2,2-diphenylethyl tert-butyl malonates via enantioselective phase-transfer catalysis

Published: June 2023

An efficient synthetic approach for chiral malonates was established via enantioselective phase transfer catalysis. The α-alkylation of 2,2-diphenylethyl tert-butyl α-methylmalonates with (S,S)-3,4,5-trifluorophenyl-NAS bromide as a phase-transfer catalyst under phase-transfer catalytic conditions successfully produced corresponding α-methyl-α-alkylmalonates; these compounds are versatile chiral building blocks containing a quaternary carbon center in high chemical yields (up to 99%) with excellent enantioselectivities (up to 98% ee). α,α-Dialkylmalonates were selectively hydrolyzed to the corresponding chiral malonic monoacids under basic (KOH/MeOH) and acidic conditions (TFA/CH2Cl2), showing the practicality of the method.
More than mcr: canonical plasmid- and transposon-encoded mobilized colistin resistance genes represent a subset of phosphoethanolamine transferases
Authors: Gaballa Ahmed , Wiedmann Martin , Carroll Laura M.

Mobilized colistin resistance genes (mcr) may confer resistance to the last-resort antimicrobial colistin and can often be transmitted horizontally. mcr encode phosphoethanolamine transferases (PET), which are closely related to chromosomally encoded, intrinsic lipid modification PET (i-PET; e.g., EptA, EptB, CptA). To gain insight into the evolution of mcr within the context of i-PET, we identified 69,814 MCR-like proteins present across 256 bacterial genera (obtained by querying known MCR family representatives against the National Center for Biotechnology Information [NCBI] non-redundant protein database via protein BLAST). We subsequently identified 125 putative novel mcr-like genes, which were located on the same contig as (i) ≥1 plasmid replicon and (ii) ≥1 additional antimicrobial resistance gene (obtained by querying the PlasmidFinder database and NCBI’s National Database of Antibiotic Resistant Organisms, respectively, via nucleotide BLAST). At 80% amino acid identity, these putative novel MCR-like proteins formed 13 clusters, five of which represented putative novel MCR families. Sequence similarity and a maximum likelihood phylogeny of mcr, putative novel mcr-like, and ipet genes indicated that sequence similarity was insufficient to discriminate mcr from ipet genes. A mixed-effect model of evolution (MEME) indicated that site- and branch-specific positive selection played a role in the evolution of alleles within the mcr-2 and mcr-9 families. MEME suggested that positive selection played a role in the diversification of several residues in structurally important regions, including (i) a bridging region that connects the membrane-bound and catalytic periplasmic domains, and (ii) a periplasmic loop juxtaposing the substrate entry tunnel. Moreover, eptA and mcr were localized within different genomic contexts. Canonical eptA genes were typically chromosomally encoded in an operon with a two-component regulatory system or adjacent to a TetR-type regulator. Conversely, mcr were represented by single-gene operons or adjacent to pap2 and dgkA, which encode a PAP2 family lipid A phosphatase and diacylglycerol kinase, respectively. Our data suggest that eptA can give rise to “colistin resistance genes” through various mechanisms, including mobilization, selection, and diversification of genomic context and regulatory pathways. These mechanisms likely altered gene expression levels and enzyme activity, allowing bona fide eptA to evolve to function in colistin resistance.
