Investigations on the Effect of Cooling Rate on Quenching & Partitioning (Q&P) in Martensitic Stainless Steels
Authors: Kresser S. , Schneider R. , Zunko H. , Sommitsch C. 
Published: August 2023

Abstract
Quenching and partitioning (Q&P) is a heat treatment used to adjust the retained austenite content in the microstructure. Such heat treatment is used mainly for low-alloyed steels. However, the partitioning effect has an influence on higher alloyed steels also, such as martensitic stainless steels. The typical heat treatment for these steels is quenching and tempering (Q&T). In large-scale tools the cooling rate in the inner area is lower than in the peripheral area, and the central region of the tool might not be cooled down completely to room temperature before the tempering step takes place, resulting in a Q&P instead of a Q&T treatment.
This article deals with these effects through dilatometric investigation of steels X40Cr14, “X25CrN13” and “X50CrMoN17-1” at two different austenitizing temperatures and two cooling rates, with a variation of the quenching temperature. It was found that partitioning takes place even at slow cooling rates. However, due to partial pearlite formation and pre-carbide precipitation/coarsening, the retained austenite content may be lower than with rapid cooling. Further, autopartitioning was also detected at slow cooling rates.

Abstract
Due to recent improvements in sensor technology, UAV-based laser scanning is nowadays used in more and more applications like topographic surveying or forestry. The quality of the scanning result, a georeferenced 3D point cloud, mainly depends on errors coming from the trajectory estimation, the system calibration and the laser scanner itself. Due to the combined propagation of errors into the point cloud, the individual contribution is difficult to assess. Therefore, we propose an entire investigation of the scan characteristics of a 2D laser scanner without the use of the other sensors included in the system. The derived parameters include the range precision, the rangefinder offset as part of the range accuracy, the angular resolution capability and the multi-target capability of the RIEGL miniVUX-2UAV. The range precision is derived from amplitude values by a stochastic model, with observations fitting a theoretical model very well. The resolution capability in the angular direction is about twice the laser beam footprint size and therefore increases linearly for larger distances. Further, a new approach with the corresponding methodology for the investigation of multi-target capability is presented. The minimum distance between two targets to appear as separated echoes within a single laser beam is about 1.6 m and inliers within the measurement precision occur from 1.9 m separation distance. The scan attributes amplitude and deviation, which are computed during the online waveform processing, show a clear systematic relation to the range precision, also in cases of multiple echoes.

Abstract

Objectives
To evaluate the impact of an Enhanced Recovery After Cesarean (ERAC) protocol on the post-cesarean recovery experience using a validated ten-item questionnaire (ERAC-Q).

Methods
This is a prospective cohort study of patients completing ERAC quality-of-life questionnaires (ERAC-Q) during inpatient recovery after cesarean delivery (CD) between October 2019 and September 2020, before and after the implementation of our ERAC protocol. Patients with non-Pfannenstiel incision, ICU admission, massive transfusion, bowel injury, existing chronic pain disorders, acute postpartum depression, or neonatal demise were excluded. The ERAC-Q was administered on postoperative day one and day of discharge to the pre- and post-ERAC implementation cohorts, rating aspects of their recovery experience on a scale of 0 (best) to 10 (worst). The primary outcome was ERAC-Q scores. Statistical analysis was performed with SAS software.

Results
There were 196 and 112 patients in the pre- and post-ERAC cohorts, respectively. The post-ERAC group reported significantly lower total ERAC-Q scores compared to the pre-ERAC group, reflecting fewer adverse symptoms and greater perceived recovery on postoperative day one (1.6 [0.7, 2.8] vs. 2.7 [1.6, 4.3]) and day of discharge (0.8 [0.3, 1.5] vs. 1.4 [0.7, 2.2]) (p<0.001). ERAC-Q responses did not predict the time to achieve objective postoperative milestones. However, worse ERAC-Q pain and total scores were associated with higher inpatient opiate use.

Conclusions
ERAC implementation positively impacts patient recovery experience. The administration of ERAC-Q can provide real-time feedback on patient-perceived recovery quality and how healthcare protocol changes may impact their experience.

The as-prepared ferritic photocatalyst’s structural, morphological, and light harvesting features have been examined in detail using well-known physical, electronic, and optical methods. The co-doped ferrite photocatalyst’s tuned structural features enable it to absorb maximum wavelengths from the U.V. and visible regions. This is because the co-doped Ni1−x

O4 photocatalyst. In application terms, the photomineralization capabilities of doped and bare ferrite photocatalysts have been explored using crystal violet (CV) dye. The comparative photocatalytic evaluation of both nickel ferrite-based photocatalysts shows that co-doped ferrite degraded 96.02 % of CV dye. In comparison, the undoped one only degraded 64.84 % after 80 min of W-lamp light exposure. The results demonstrated that the Ho and Co co-doped ferrite photocatalyst exhibits excellent photocatalytic activity, suggesting its potential for environmental remediation applications in textile industrial discharges.

Published: August 2023

AbstractNanog and Oct4 are core transcription factors that form part of a gene regulatory network to regulate hundreds of target genes for pluripotency maintenance in mouse embryonic stem cells (ESCs). To understand their function in the pluripotency maintenance, we visualised and quantified the dynamics of single molecules of Nanog and Oct4 in a mouse ESCs during pluripotency loss. Interestingly, Nanog interacted longer with its target loci upon reduced expression or at the onset of differentiation, suggesting a feedback mechanism to maintain the pluripotent state. The expression level and interaction time of Nanog and Oct4 correlate with their fluctuation and interaction frequency, respectively, which in turn depend on the ESC differentiation status. The DNA viscoelasticity near the Oct4 target locus remained flexible during differentiation, supporting its role either in chromatin opening or a preferred binding to uncondensed chromatin regions. Based on these results, we propose a new negative feedback mechanism for pluripotency maintenance via the DNA condensation state‐dependent interplay of Nanog and Oct4.

Perdebatan antara Islam sebagai agama ataupun ideologi dengan roda perpolitik di rezim orde baru penuh dengan dinamika. Masa awal Orde Baru sampai akhir tahun 1980-an bisa dikatakan bahwa Islam di Indonesia banyak berada di luar arena kekuasaan (Sukamto, 2008: 4). Namun di awal tahun 1990- an Suharto selaku presiden mulai merangkul kalangan Islam. Perubahan sikap rezim tersebut berdampak pada munculnya berbagai kajian-kajian keislaman dan pada akhirnya bersentuhan dengan kelompok kesenian. Salah satunya adalah kelompok teater di Jakarta yang dimotori oleh Zak Sorga, yaitu Teater Kanvas yang pada akhirnya mentransformasikan ideologi pertunjukannya menjadi sebuah pertunjukan Teater Islami. Yang menjadi pertanyaan dalam penelitian adalah bagaimana proses transformasi ideologi pertunjukan Teater Kanvas dan mengapa Teater Kanvas melakukan transformasi ideologi dalam pertunjukannya? Penelitian ini bertujuan untuk mengetahui bagaimana proses transformasi ideologi Teater Kanvas dari ideologi alienasi menjadi Teater Islami. Dari proses tersebut penulis ingin mengetahui penyebab teater kanvas melakukan transformasi ideologi dalam pertunjukannya dan melihat dampak transformasi ideologi tersebut terhadap pertunjukan mereka. Penelitian ini menggunakan metode kualitatif dengan pendekatan etnografi yang bertujuan untuk melihat bagaimana proses transformasi ideologi pertunjukan pada salah satu kelompok Teater di Jakarta, yaitu Teater Kanvas.

Published: August 2023

Pancasila telah dinyatakan kedudukannya oleh para pendiri negara Republik Indonesia sebagai cita hukum (rehtsidee) yang merupakan konstruksi berpikir dan untuk mengarahkan hukum kepada tujuan yang hendak dicapai oleh masyarakat. Cita hukum berfungsi sebagai pemandu tercapainya tujuan masyarakat. Cita hukum juga berfungsi sebagai dasar yang bersifat konstitutif -baik das sollen maupun das sein. Sejarah menunjukkan bahwa perjuangan menegakkan hukum agama (Islam) di wilayah negara Indonesia sering mengalami masa-masa ketegangan dan tarik ulur kekuatan yang cukup melelahkan. Ketegangan tercipta akibat relasi warga dengan negara; maupun warga dengan negara lain yang berbasis pada pemaknaan agama dalam bernegara. Bentuk relasi agama (Islam) dengan negara dapat dilacak dalam jejak produk peraturan perundangan yang ada maupun dalam praktek ketatanegaraan di Indonesia. Pada wilayah inilah politik hukum suatu negara memiliki peran penting dalam menentukan pelaksanaan dan warna hukum yang berkembang dalam wilayah negara tersebut. Artikel ini bertujuan untuk meneliti bagaimana hubungan agama dan negara di Indonesia dalam pembentukan hukum sehingga dapat menemukan kesepakatan yang harmonis dan sistemik.

Published: August 2023

Kewenangan Mahkamah Konstitusi mengadili pada tingkat pertama dan terakhir dalam hal menguji Undang-Undang terhadap Undang-Undang Dasar diatur dalam pasal 24 C ayat (1) UUD NRI 1945. Putusan Mahkamah Konstitusi bersifat final and mengikat artinya semua pihak harus mentaati dan melaksanakannya. Berkaitan dengan wewenang tersebut Mahkamah Konstitusi mengeluarkan dua jenis putusan yaitu putusan yang bersifat self executing dan non self executing. Tulisan ini hendak menjawab permasalahan tentang implikasi yuridis putusan Mahkamah Konstitusi yang bersifat non self executing. Mahkamah Konstitusi dapat melakukan judicial order berlandaskan Pasal 10 dan 23 UU No. 15 Tahun 2019 perubahan atas UU No. 12 Tahun 2011 tentang Pembentukan Peraturan Perundang-Undnagan. Dalam pelaksanaan putusan yang bersifat self executing tercantum pada pasal 10 ayat (1) huruf d tentang pedoman beracara dalam perkara pengujian UU dalam Peraturan Mahkamah Konstitusi No. 6 Tahun 2005, sedangkan secara tersirat pelaksanaan putusan yang bersifat non self executing tercantum pada Peraturan Mahkamah Konstitusi No. 3 Tahun 2019 tentang Produk hukum Mahkamah Konstitusi dan pada BAB III Pasal 27 hingga pasal 31 Peraturan DPR No. 13 tahun 2016 tentang tata cara penyusunan program legislasi nasional. Beberapa aturan tersebut sangat berkaitan erat karena menjelaskan pelaksanaan putusan Mahkamah Konstitusi secara yuridis yang bersifat non self executing. Setelah putusan, kewenangan tersebut dilimpahkan kepada lembaga legislatif dan Presiden, implementasinya harus sesuai dengan asas-asas pembuatan, pembentukan, dan penetapan produk hukum yang baik dan melalui program legislasi nasional agar tidak adanya kekosongan hukum dan menghambat jalannya politik serta pemerintahan.
Efukwini: Sacredness and the aesthetics of birth amongst amaXhosa.
Authors: Penxa-Matholeni Nobuntu 
Published: August 2023

Efukwini is an IsiXhosa concept that refers to a birthplace in an umXhosa home. It is where the mother and her new-born will spend the first 10 days of his/her life away from the rest of society, attended to by a select group of older women or guardians. During this time, the child will be given a name and ukuwisa (the falling off of the stump of the umbilical cord) which is called inkaba is expected to take place. In short, this ritual takes the foetus from birth to babyhood. Similarly, a parallel can be drawn between ulwaluko (the initiation ritual), which takes a boy to manhood. Newly graduated initiates are referred to as amakrwala, a name bestowed upon them during the process of ulwaluko. The young male initiates are to remain inside the ceremonial home for the first week. Both these rituals are considered sacred among the amaXhosa people. However, in more recent times, the birth ritual has lost its appeal. This article therefore seeks to discuss, explain and theorize the purpose and meaning of the practice of efukwini from a narrative pastoral care perspective. A secondary aim is to understand why less emphasis has been placed on the ritual of childbirth while the practice of ulwaluko has survived the transition into modern day IsiXhosa culture.

Published: August 2023

El artículo tiene como objetivo principal presentar una propuesta para la mejora de procedimientos en la concesión de créditos en una entidad financiera del Ecuador, a través de la metodología Kanban dado que actualmente los procesos se realizan de una manera obsoleta con trámites extensos que generan cuellos de botella y mayor tiempo de respuesta para el cliente; de esta forma con la propuesta se espera reducir costos de producción y a su vez maximizar los rendimiento financieros y económicos de la entidad objeto de estudio. Se plantea un diseño de investigación cuantitativo, de tipo descriptivo que permitió deducir la situación financiera de la entidad para solventar las necesidades al implementar la metodología Kanban en los procesos para otorgar créditos. Se estableció que en la entidad financiera el proceso para un crédito genera un tiempo en oficina de 24 horas y al agregar el tiempo promedio de traslado de documentos físicamente suma un total de 32 horas, es decir, el proceso demora en promedio 4 días desde su inicio con el asesor hasta terminar con el archivo del expediente. Al aplicar la metodología Kanban se reduce el tiempo del proceso a un estimado de 2 días generando un proceso más eficaz, disminuyendo costos e incrementando la productividad y el desempeño de todo el equipo de trabajo; se ha estimado que la entidad tendrá un aumento del 50% de su productividad tomando como referencia las variaciones relativas del análisis horizontal que cada rubro tiene en el estado de resultados.

El Rábano (Rhapanus sativus) es una hortaliza que se cultiva a nivel mundial por lo que, muchos productores utilizan químicos para tener mayor producción, una alternativa para evitar el uso de químicos en el cultivo de rábano es el uso abonos verdes a base de algas por sus ventajas nutricionales que pueden aportar a la agricultura. El objetivo de este trabajo fue evaluar el comportamiento agronómico y productivo del rábano “Raphanus sativus” bajo el efecto de la biofertilización a base de la macroalga Porphyra umbilicalis también conocida como “Nori”. Se utilizo un Diseño Completamente Alzar (DCA) con cuatro tratamientos y un testigo experimental con cinco repeticiones. Los tratamientos corresponden a T0: control experimental (0% de alga Nori); T1 al 100% de alga Nori; T2 al 75% de alga Nori; T3 al 50% de alga Nori; T4 al 25% de alga Nori. Se utilizaron 10 plantas por unidad experimental, es decir, 50 plantas por tratamiento con un total de 250 plantas para todos los tratamientos. Los resultados indicaron que, la exposición del alga Nori previo a la siembra, no representó ninguna ventaja en el porcentaje de emergencia, no obstante, en las variables de altura (34.32 cm) Ancho de hojas (9.18±1.45), Longitud de Hoja (2 ±0.69), Peso (31.6±3.14 g), biomasa fresca (23.90±2.59), Biomasa seca (1.57±0.41) y rendimiento 31.2 kg el tratamiento T4 biofertilizados con el 100% de alga Nori presentó los valores más altos. Concluyendo que el uso de alga Nori como biofertilizante puede dar ventajas en la producción de hortalizas como el rábano.
