Authors: YAMAN Barbaros , AKYOL Ali Akın , PULAT Esra , YILDIZ Ayşe
Published: March 2023

Tarihi yapıların onarımında, çürümüş veya hasar görmüş ahşap elemanların veya bunların parçalarının değiştirilmesinin zorunlu olduğu durumlarda, kullanılacak ikame ahşabın orijinal tür ile aynı ve doğal yapıda olması gerekmektedir. Bu nedenle ahşabın mimari yapı malzemesi olarak kullanıldığı tarihi binaların restorasyonunda, orijinal ahşap malzemenin teşhisi büyük önem arz etmektedir. Anadolu Selçuklu Dönemi'nde, 1272-1277 yılları arasında Sahipata Nusretiddün Hasan tarafından yaptırılan ve mimarı Emir Hacı Bey olan Afyonkarahisar Ulu Cami, ahşap işçiliği ve sırlı tuğlalı baklava dilimi tuğla mimarisiyle Selçuklu Dönemi'nin eşsiz örneklerinden birini temsil etmektedir. Afyonkarahisar Ulu Cami’nin mahfil ve mihrabının farklı yerlerinden alınan ahşap parçalarının ksilolojik analiz sonuçları mahfilin yapımında Karaçam (Pinus nigra Arnold) veya Sarıçam (Pinus sylvestris L.), mihrabında ise Ceviz (Juglans regia L.) odunu kullanıldığını göstermiştir. Karaçam ve Sarıçam odun anatomisi özelliklerine göre birbirinden ayrılamasa da, caminin bulunduğu coğrafi konum ve Karaçamın doğal yayılış alanları düşünüldüğünde, belirtilen çam örneğinin Karaçam olabileceği kanaati oluşmaktadır.

This research examines the management of election violations abroad, a crucial factor in the quality of Indonesia's elections. The rise in such cases during the 2019 general election highlights the need for a robust framework to address these issues in the upcoming 2024 elections. Unlike previous studies, this research focuses on creating an effective design for managing election violations. The findings emphasize the urgent need for effective oversight to ensure order, protect citizens' constitutional rights, and uphold justice. To achieve this, the study recommends increasing the Overseas General Elections Supervisory Committee's membership from three to five, amending key legal provisions, and shifting the law enforcement paradigm from compliance to the internalization of legal compliance. These measures aim to enhance the integrity and effectiveness of Indonesia's electoral process.
Delays in international criminal justice : What impact does it have on victims' rights ?
Authors: Manzanga Kpanya Ovide
Published: March 2023

This study aims to argue that the time of the criminal response at the international level is one neglected factor with unpredictable and sometimes irreversible consequences on the rights of victims. Speaking of delays, the idea is to demonstrate that this justice system does not react or act within a time limit that would prevent the deterioration of a situation, already disastrous and unbearable, in which the victims of these crimes. The resulting conclusions reveal that the set of rights enjoyed by these victims, until now, are not sufficient to protect them against these delays. And yet, the suffering they endure from the commission of these crimes justifies a substantial strengthening of their rights in order to avoid additional tortures, arising over time as long as justice has not resolved these conflicts, and will not have restored them to their violated rights.

Chronic limb-threatening ischemia, also known as critical limb ischemia (CLI), is the most advanced stage of peripheral arterial disease (PAD), and patients have high risk of major lower-limb amputation and mortality. An endovascular-first approach has become the preferred revascularization strategy for these patients. The aim of the study was to evaluate the safety and short-term efficacy of the Ranger paclitaxel-coated balloon (PCB; Boston Scientific) in the setting of CLI. Methods. This was a single-center, single-arm, multi-investigator, prospective study of CLI patients who underwent endovascular revascularization using the Ranger PCB from July 2019 to November 2019 at Singapore General Hospital in Singapore. Data were retrieved from the Vascular Quality Initiative database recently set up at this institution. Primary lesion patency, amputation-free survival (AFS), freedom from target-lesion revascularization (TLR), and complete wound healing were the efficacy endpoints of interest at 6 months post intervention. Results. A total of 84 patients (87 limbs; 229 lesions) were enrolled. Fifty-one of the 84 patients (60.7%) were men. Baseline characteristics included diabetes mellitus in 76/84 patients (90.5%), chronic renal impairment in 25/84 patients (29.8%), and Rutherford category 6 foot wounds in 22/87 limbs (24.7%). TASC D lesions were present in 63/229 lesions (27.9%) and moderate/severe vessel wall calcification was present in 167/229 lesions (72.9%). Immediate technical success was achieved in 218/229 lesions (95.2%) with no device-related mortality at 30 days. Primary patency rates at 3 months and 6 months were 76/82 (92.7%) and 69/81 (85.2%), respectively. Six-month primary patency rates of below-the-knee (BTK) lesions treated with and without Ranger balloons were 89/94 (94.7%) and 34/41 (82.9%), respectively (P=.03). Six-month AFS occurred in 68/78 (87.2%) and freedom from TLR occurred in 73/81 (90.1%). Six-month complete wound healing rate was respectable, at 28/50 (56.0%). Conclusion. Use of the Ranger PCB showed favorable outcomes and short-term patency rates, especially in the BTK region, in what is an otherwise challenging patient cohort. Extended follow-up is awaited to evaluate the long-term safety and efficacy of the balloon.
Square wave voltammetry enables measurement of light-activated oxidations and reductions on n-type semiconductor/metal junction light-addressable electrochemical sensors
Authors: Arthur Enock , Ali Hana , Hussain Armeen , O'Neil Glen
Published: March 2023

Light-addressable electrochemical sensing (LAES) is a photoelectrochemical technique that enables high-density, individually addressed electrochemical measurements using light to activate an electrochemical reaction at the surface of a semiconducting photoelectrode. However, one major challenge is that only one electrochemical reaction (oxidation or reduction) will be activated by light. Here, we use square wave voltammetry (SWV) to enable measurements of both types of electrochemical reactions using n-Si/Au NP LAE sensors. We demonstrated this approach for the oxidation of ferrocene methanol and the reductions of ruthenium hexamine and methylene blue. We found that for all molecules, SWV showed dramatic improvements in current under illumination in comparison with dark samples. We also demonstrate that this approach works for both fully illuminated and partially illuminated samples. Altogether, we hope these results open up new applications for LAE sensors, especially those based on semiconductor/metal junctions.

Published: March 2023

An environmentally friendly method for creating sustainable alternatives to traditional aromatic-aliphatic polyesters is a valuable step towards resource-efficiency optimization. A library of furan-based block copolymers was synthesized via temperature-varied two-step polycondensation reaction in diphenyl ether using Candida antarctica lipase B (CAL-B) as biocatalyst where dimethyl 2,5-furandicarboxylate (DMFDCA), α,ω-aliphatic linear diols (α,ω-ALD), and bio-based dilinoleic diol (DLD) were used as the starting materials. Nuclear magnetic spectroscopy (1H and 13C NMR), Fourier transform spectroscopy (FTIR) and gel permeation chromatography (GPC) were used to analyze the resulting copolymers. Additionally, crystallization behavior and thermal properties were studied using X-ray diffraction (XRD), digital holographic microscopy (DHM), and differential scanning microscopy (DSC). Finally, oxygen transmission rates (OTR) of furan-based copolyesters were verified. The results showed that the diol chain length of α,ω-ALD used in the synthesis of poly(alkyl furanoate-co-dilinoleic furanoate) copolymers had a significant effect on the material molecular weight, thermal properties, crystalline structure and oxygen permeability.
Expanded Coverage of Phytocompounds by Mass Spectrometry Imaging Using On-Tissue Chemical Derivatization by 4-APEBA

Published: March 2023

Probing the entirety of any species metabolome is an analytical grand challenge, especially at a cellular scale. Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a common spatial metabolomics assay, but this technique has limited molecular coverage for several reasons. To expand the application space of spatial metabolomics, we developed an on-tissue chemical derivatization (OTCD) workflow using 4-APEBA for confident identification of several dozen elusive phytocompounds. Overall, this new OTCD method enabled the annotation of roughly 280 metabolites, with only 10% overlap in metabolic coverage when compared to analog negative ion mode MALDI-MSI on serial sections. We demonstrate that 4-APEBA outperforms other derivatization agents providing: (1) broad specificity towards carbonyls, (2) low background, and (3) introduction of bromine isotopes. Notably, the latter two attributes also facilitate more confidence in our bioinformatics for data processing. The workflow detailed here trailblazes a path towards spatial hormonomics within plant samples, enhancing detection of carboxylates, aldehydes, and plausibly other carbonyls. As such, several phytohormones, which have various roles within stress responses and cellular communication can now be spatially profiled, as demonstrated in poplar root and soybean root nodule.

Ngā Manu ā Tāne – the stories of Māori doctoral students in Aotearoa: An ethnographic study
Authors:   , Funaki Hine
Published: March 2023

Ko te manu e kai ana i te miro, nōna te ngahere;
Ko te manu e kai ana i te mātauranga, nōna te ao
Ko te manu e whakatinana ana i ērā mātauranga, nōna te whenua taurikura (Ratana, 2022).

The bird that feeds on the miro berry can rule the forest
The bird who feeds on knowledge can rule the world
The bird who embodies that knowledge can be responsible for thriving homelands

Previous studies show that Māori PhD students in Aotearoa face significant structural and systemic barriers during their doctoral studies, but little is known about how they meet and surmount those daily challenges.

Through a Kaupapa Māori lens, which places Indigenous storytelling at the centre of inquiry, this study frames an explanation to the complex, relational spaces that Māori doctoral students grapple with in academia. Further, it provides insight into their everyday worlds as Indigenous scholars who are pioneering new forms of intellectual engagement inside the settler-colonial complex of the Aotearoa university system.

This is a cross-sectional, ethnographic ‘day-in-the-life’ approach which captures not only the intellectual and cultural life-worlds, but the often silenced stories of a nationwide cohort of Māori doctoral students. Their micro-level experiences of entry into academic environments that marginalise Indigenous knowledges and realities are set against larger institutional, structural, and political factors. These influences have exerted a powerful impact on the degree of cultural and intellectual belonging that these Māori scholars have been able to establish within their academic departments.

Kanohi-ki-te-kanohi (face-to-face/in-person), online, walk-along, and drive-along interviews were conducted with 30 Māori doctoral students and recent PhD graduates across Aotearoa. Observations were also carried out in their work and study locations, which included their homes, workplaces, university offices, and tribal communities.

The participants’ accounts focused heavily on the lack of Māori representation at all levels of academia and the subsequent impact on their scholarly lives. For many students, limited access to Māori expertise, mentoring, supervision, and cultural validation heightened a profound sense of cultural dislocation and intellectual isolation. During these times, Ngā Manu (the collective name for participants in this study) also sharpened their determination to establish safe academic environments for the next generation of Māori scholars. Despite significant challenges, the participants also spoke of the everyday triumphs, the moments of recognition and shared purpose in the company of Māori PhD colleagues. In these cultural safe spaces, they shared moments of creativity, pleasure, and joy, as they established their own unique academic selfhoods, which they saw both as a legacy for Māori who would follow after them into the academic world, and a means of ‘speaking back’ to the racialised silences of the ivory tower.

Authors: Zhang Lu , Li Guangjun , Nan Lin , Liu Shuyan
Published: March 2023

Asphalt pavement is currently one of the main components in the construction of roads and bridges. However, from a practical point of view, various quality problems are prone to occur in the surface layer of asphalt pavement, which will lead to the poor overall quality of road and bridge projects. Therefore, it should be applied reasonably. Advanced testing technologies are used to test the mixture quality, compaction, segregation, thickness, and other aspects of the asphalt pavement surface layer, so as to improve the quality of the asphalt pavement surface layer, and then improve the overall quality of road and bridge construction. Therefore, this paper mainly analyzes the technologies for asphalt pavement surface layer testing in road and bridge engineering construction.

Tata kelola pemerintahan tidak hanya menjadi kajian yang dilematis di ranah pemerintahan pusat dan daerah, namun juga di taraf pemerintahan desa. Kebijakan pembangunan dengan memberikan dana desa di setiap desa di ilayah Republik Indonesa membuat tidak hanya desa sebagai sebuah wilayah terdampak modernisasi pembangunan, tapi juga diimbangi dengan kebutuhan sumber daya manusia termasuk aparatur desa di dalamnya untuk terus melakukan pembaruan pengetahuan serta kemampuan dalam pengelolaan dana desa tersebut. Salah pengelolaan, atau bahkan salah pengadministrasian dalam mengelola dana desa tidak hanya berdampak pada kemunduran pembangunan desa, tapi juga dianggap sebagai budgeting fraud dan termasuk dalam tindak korupsi. Pengabdian kepada masyarakat ini mencoba tidak hanya memberikan sharing knowledge terkait isu-isu tata kelola pemerintahan tapi juga memberikan pendampingan terkait pengadministrasian serta pengelolaan dana desa yang sesuai dengan peraturan-peraturan yang berlaku. Hasil dari agenda ini diharapkan mampu memberikan pemahaman serta praktek pengadministrasian serta perencanaan pengelolaan dana desa agar terhindar dari upaya-upaya penyalahgunaan keuangan (korupsi).

English has become the universal communication language of business, tourism, education, technology, and science. Developing students' oral skills in the classroom has become a great challenge for English teachers since there are limitations to producing the target language. Therefore, the main purpose of this study was to identify the factors that prevent the English oral production of students of first and second year of bachillerato. This research used a quantitative approach where a survey and an observation guide for students and teachers were applied to collect the data in[1]formation. The population of this study was 34 students and a teacher. The main results showed that learners cannot produce speaking skills because they are afraid of making mistakes in their oral presentations and they consider that English is difficult to pronounce. Additionally, the negative affective factors such as anxiety, pressure, nervousness, and apprehension influenced directly in their oral performance. These hindrances that learners face daily in the classroom can be diminished through constant motivation and confidence. Hence, it is advisable the frequent use of interesting and dynamic activities that promote communication in real situations and in that way to accomplish the academic goal which is to enhance students’ oral proficiency.
Soliton phenomena in the process of the functioning of the heart

The biochemical model explains the intricate mechanisms of psychobiological life. He still cannot explain what the transition from inanimate to living matter is all about. Where is the threshold and what is its essence, what role do biochemical processes play in the coherence of the soma with consciousness and its impact on the soma and vice versa? A similar problem is with other mental processes, their nature does not fit into the biochemical model of life and is inexplicable on the basis of biochemical interactions, again it is much easier to describe it in the light of quantum processes - including wave physics. It is similar to the functioning of the heart or other organs, where only the biochemical processes of the cell are considered, ignoring the bioelectronic processes. Man is not only a purely biological construct but also contains the basis of biochemical, bioelectronic, information, and cybernetic processes that are responsible for shaping the psychobiological processes of man. Contemporary biosystems in science are considered at the level of corpuscular structures, ignoring energy and information structures. By shifting the cognitive emphasis towards energy and information structures, the organism can be perceived as a quantum generator of information: electromagnetic, soliton, acoustic, spin and bioplasma. This bioelectronic construction creates homo electronics with his electronic personality.

This article examines the sub-district institution in Pandeglang Regency's ability to implement its capacity as an autonomous region feature as well as the administrative region feature of universal government administration, as well as the fulfillment of the necessary condition element. It also offers a recommendation model for the delegation of Regent authority to the sub-district head based on the empirical situation. Attempts at the research were made utilizing a qualitative methodology. The study's findings demonstrate that in the Pandeglang Regency, the legal authority granted by the Regent is still not directly correlated with the fulfillment of necessary condition elements of sub-district institutions like human resources and budget. Then, in terms of the camat's or district's legal authority, some aspects—such as the alteration of laws and regulations, regional characteristics, the spirit of institutional strengthening in public services, and the requirements of coordinating national development programs—remain to require some adjusting. In order to achieve the efficacy of the sub-district institution in the administration of regional government, the Pandeglang district government is expected to implement a number of arrangements and restructuring of the sub-district institution under the suggested model.

SMAW (Shielded Metal Arc Welding) welding is a metal joining process that uses heat energy to melt the workpiece and electrode (fill material). The flux material used for type E7016, a low hydrogen electrode wire typically used for welding heavy-duty plates and structures. Its use is for welding medium carbon steel, bridges, ships and machinery. The result of welding electrode E7016 is very smooth, deep penetration, crack resistant, ductile, good weld appearance and stable arc, the material used in the SMAW welding process is AISI 1050 steel. While AISI 1050 steel is steel that has a carbon content of 0.50 % so that it is classified as medium carbon steel. This steel is widely used in the market because it has many advantages, one of which is as an automotive component. This steel has the characteristics of good machinability, good wear resistance and medium mechanical properties. This study aims to determine the shock strength (impact) and the difference in the time of making weld grooves on SMAW welding results on AISI 1050 steel with variations of Double Bevel and Double V Groove grooves. In testing in the Weld Metal area with a current used of 110 Ampere. From the tests that have been carried out, it is known that the value of the highest impact strength is in the Double Bevel groove which has a value of 1.91 Joule/mm2, for the manufacture of welded grooves where the Double Bevel time is shorter than Double V Groove, so the time produced by Double Bevel which is 3.44 minutes/second.
