Çift-yönlü dokuma kumaş takviyeli kompozit levhalarda mekanik özelliklerin anizotropiye bağlı değişimi ve optimum laminasyon tasarımı önerisi
Authors: Sakin Raif
Published: September 2024

Bu çalışmanın ilk amacı, çift-yönlü dokuma kumaş takviyeli kompozit levhalarda mekanik özelliklerin anizotropiye bağlı değişimini incelemektir. Diğer amaç ise kompozit levha üretiminde mekanik özelliklere ve anizotropiye dayalı optimum laminasyon tasarımını (istifleme sırası) belirlemede kullanılabilecek grafiksel bir yöntemi açıklamaktır. Bu amaçlar için gerekli levhaların imalatında reçine transfer kalıplama yönteminden yararlanılmıştır. Matris ve fiber malzeme olarak sırasıyla, düşük viskoziteli ticari bir polyester reçine ile dört farklı alansal ağırlığa sahip çift-yönlü düz cam-dokuma kumaşlar kullanılmıştır. Her bir levhada kullanılan fiber ağırlığı 750 g ve levhanın merkezinden geçen orta-düzleme göre simetrik olmak şartıyla on farklı laminasyon tasarımı denenmiştir. İmalat prosesi sonunda kalıptan 50 × 50 cm boyutlarında farklı katman sayısı, farklı kalınlık ve fiber hacimlerine sahip olan kompozit levhalar elde edilmiştir. Levhalardan 0°, 15°, 30° ve 45° yönlerinde standartlara uygun numuneler kesilerek, bunların çekme ve eğilme gibi mekanik özellikleri test edilmiştir. Ayrıca, her bir levhanın laminasyon tasarımı ve fiber oryantasyonuna bağlı olarak mekanik anizotropi faktörleri hesaplanmıştır. Toplam 365 adet numune test edilmiş ve veriler SPSS-24 yazılımıyla istatistik olarak analiz edilmiştir. Mekanik özelliklerin tahmini için fiber hacmi, katman sayısı, levha kalınlığı ve fiber oryantasyonu gibi değişkenlere bağlı olarak regresyon denklemleri elde edilmiştir. Bütün çekme, eğilme mukavemeti ve modül verileri MS-Excel’e taşınarak radar (spider) grafikleri çizilmiş ve bu grafikler okunarak optimum laminasyon tasarımları önerilmiştir.

Bu çalışma ile, yapım çalışmaları Karayolları 9. Bölge Müdürlüğü tarafından yürütülen Siirt İli’ne bağlı Aktaş Köyü mevkiinde karayolu inşaası çalışmaları sırasında, dolgu kesiminde meydana gelen stabilite problemlerinin limit denge ve sonlu elemanlar yöntemi ile statik ve depremli durum analizlerinin yapılarak güvenlik sayıları ve göçme yüzeyleri bakımından kıyası yapılmıştır. Çalışma alanında yüksek yarma ve dolgu kesitlerine rastlanmaktadır, bu sebeple bu kesim kritik bir öneme sahiptir. Heyelanın meydana geldiği kesimlerde gerekli arazi çalışmaları yapılmış ve elde edilen zemin ve kaya numuneleri ile laboratuvar deneyleri yapılmıştır. Arazi incelemeleri, laboratuvar ve literatür verileri ışığında analizler için gerekli kayma mukavemeti parametreleri elde edilmiştir. Stabilite problemlerinde kayma yüzeyinin yerini ve şeklini belirlemek zordur. Mevcut durumu yansıtan model üzerinde, sonlu eleman yönteminin yansıtıldığı Plaxis 2D V ile limit denge yöntemine dayanan Slide V.6 yazılımlarından yararlanılmış, şevin göçme yüzeyi tespit edilmeye çalışılmış ve güvenlik analizi hesapları yapılmıştır. Güvenlik sayıları yönünden iki yöntem uyumlu görünse de sonlu elemanlar yöntemi ile elde edilen güvenlik sayıları daha düşük çıkmıştır. Ayrıca zemindeki yenilme bölgelerinin yerlerinin belirlenmesi ve gerilme deformasyon eğrilerinin elde edilmesi açısından sonlu elemanlar yönteminin daha olumlu ve güvenilir sonuçlar verdiği tespit edilmiştir.
Sıvı sönümleyici ile tarihi minarelerin deprem tepkisinin iyileştirilmesinin lineer dinamik analizi
Authors: Yiğit Muhammet Ensar
Published: September 2024

Bu çalışmada tarihi camii minarelerinin yapısal değişikliğe gitmeden uygulanabilecek sıvı sönümleyici modelleri ile sismik tepkilerinin iyileştirilmesi araştırılmıştır. Literatürde sıvı sönümleyici ile minare davranışının incelendiği çalışmalara pek rastlanmamıştır. Sıvı sönümleyicinin etkisini görebilmek için minarenin mevcut hali ile petek kısmında ve şerefe kısmında sıvı sönümleyici bulunan modeller kıyaslanmıştır. Bu modellerin 1999 Düzce deprem kaydı ile doğrusal dinamik analizleri yapılmıştır. Birleşik Eularian-Lagrangian yaklaşımı ile akışkan-yapı etkileşimi kurulmuş, analiz süresince sudaki çalkantılar izlenmiştir. Analizler sonucunda, sıvı sönümleyici olarak su kütlesini bütün olarak hareket edecek şekilde modellemek yerine, gözenekli veya çıtalı bölmeler şeklinde yapmak sönümlemede daha etkili olduğu görülmüştür. Sıvı sönümleyici olan modellerde göreceli yer değiştirmelerde azalma gözlemlenmiştir. Ayrıca sönümleme etkisi ve sıvı ağırlığı çekme gerilmelerinde (Smax) azalmaya sebep olurken basınç gerilmelerinde (Smin) artışa sebep olmuştur. Tüm modellerde en büyük asal basınç gerilmeleri ve en büyük asal çekme gerilmeleri minarelerin genellikle depremlerde hasar aldığı kaide ile gövde arasındaki bir alanda yoğunlaşmıştır. Analizler, minarenin sıvı sönümleyici ile iyileştirilmesinin depreme dayanıklılığı artırdığını, bu nedenle güçlendirme öncesinde akışkan-yapı etkileşiminin dikkate alınması gerektiğini göstermektedir.
Multi-scale Residual Segmentation Network for Histopathological Image
Authors: Bozdağ Zehra , Talu Muhammed Fatih
Published: September 2024

Deep learning is used in all areas of the image processing like object detection/localization, synthetic image generation, segmentation, tracking, and others. It is frequently used especially in medical image segmentation field since it provides rapid response during the treatment process. The fact that natural images contain different types of noise, patterns, and structures and the lack of distinctive quantitative information still makes the segmentation problem very challenging. The classical networks having high parameters have a long training time. The need of less training time for high parameter networks and high segmentation accuracy has led us to develop a new network. In this study, a state-of-the-art autoencoder network (MSRSegNet) is proposed to perform segmentation. Unlike conventional autoencoder approaches, it consists of encoder, fusion and decoder blocks. In encoder and decoder blocks, Multi-scale Residual Blocks are used to share information between blocks and to detect features on different scales. In fusion block, Atrous Spatial Pyramid Pooling (ASPP) module is used to preserve multi-scale contextual information. Information sharing between blocks has increased the ability of the proposed method to capture global features. The performance parameters of mean intersection over unit (mIOU) and pixel accuracy (PA) is used to compare the results. As a result, it was observed that the proposed segmentation network has high accuracy (69% mIoU) and fast segmentation performance (0.061sec. for an image with 256x256)

Published: September 2024

Ruminants are grazing animals with the ability to utilize forage sources for maintenance, growth, reproduction and production. They possess the rumen, a fermentation chamber composed of high diversity of microorganisms with the ability for degrading fiber or starch rich food and other types of non-fibrous carbohydrates, since they contain enzymes that act by breaking up bonds between molecules, making the substrate present in the food available. This study was developed aiming at reviewing the literature on how different diets affect ruminal parameters as well as the rumen ecology. Thus, the seeking for the understanding on how different diets can affect ruminal characteristics is found to be important, since it makes possible manipulating the diet up to a threshold, without causing any metabolic disturbance to animals and then maximizing the performance. This practice may contribute to minimize losses, maximize the food fermentation process and the absorption of fermentation products, which can be converted into flesh and milk. Findings from this study show that the microbial population and the final rumen fermentation products are directly affected by the animal diet. Therefore, manipulating diets may make possible maximizing the animal productive efficiency, as well as the optimization of the use of nutrients, to maximize the animal production.

Authors: Arias-Hernández Alberto , Gomez-Beltran David Alberto , Villar-Argaiz David
Published: September 2024

Canina raza caniche de 11.5 años se remitió con una historia incierta de posible hiperadrenocorticismo. La exploración física y exámenes paraclínicos evidenciaron signos y hallazgos presuntivos de hiperadrenocorticismo incluyendo: letargo, distensión abdominal, polidipsia/poliuria, jadeo, hipostenuria, linfopenia, elevación de enzimas hepáticas. Se hicieron dos pruebas hormonales de valoración del eje hipotálamo-hipófisis (o pituitaria)-adrenales (HHA ó HPA): prueba de supresión con dosis baja de dexametasona y medición de la hormona corticotropa (ACTH) endógena. El cortisol basal en suero estaba ligeramente elevado con un valor de 8.52 µg/dL (normal = 1.8 – 6.0). Los valores de cortisol a las 4 y 8 horas post-administración de dexametasona fueron de 2.46 y 6.91 µg/dL, respectivamente. Dichos resultados evidenciaron una falta de supresión a las 4 horas (concentraciones >1.4 µg/dL) y 8 horas (concentraciones >50% del valor basal). Además, el hecho de que a las 4 horas post-administración de dexametasona los valores estuviesen en 2.4 µg/dL, superando el punto de corte de 1.4 µg/dL, es sugerente de que el hiperadrenocorticismo no era de origen pituitario y sí de origen adrenal. El diagnóstico fue corroborado por la prueba endógena de ACTH, cuyos valores estuvieron por debajo del rango de referencia: 10 pg/mL (15,0 - 60,0 pg/mL). En conclusión, los pasos a seguir en el diagnóstico de hiperadrenocorticismo comienzan por un buen análisis clínico y laboratorial antes de realizar pruebas hormonales específicas para valorar el eje HPA. Del punto de vista de la terapia, es importante diferenciar entre hiperadrenocorticismo de origen pituitario y adrenal.

Spilogale angustifrons cuenta con una amplia distribución en el sureste de México, sin embargo, para la región de Calakmul el conocimiento es escaso. Se reportan nuevos registros de S. angustifrons en la región de Calakmul, Campeche, México. Con un esfuerzo acumulado de 9000 noches-trampa, se obtuvieron 18 fotografías de S. angustifrons que corresponden a 15 eventos independientes, en cuatro estaciones de fototrampeo colocadas en la región de Calakmul. En las estaciones de fototrampeo se registraron cuatro eventos fotográficos en los que se observan a individuos machos, solitarios, pero no fue posible identificar si los registros corresponden a uno o más individuos. Los pocos registros de S. angustifrons en la Península de Yucatán puede deberse a la falta de prospecciones mastozoológicas en la región. Los registros reportados en esta nota, aportan conocimiento sobre la distribución, hábitat, uso de bebederos artificiales y relaciones interespecíficas de S. angustifrons. Al ser un carnívoro es probable que el papel ecológico de S. angustifrons en la región de Calakmul sea relevante, sin embargo los aspectos poblacionales y ecológicos de la especie se desconocen, por lo que es necesario realizar estudios enfocados a conocer el estado de las poblaciones de S. angustifron.

Published: September 2024

Se evaluó la producción de biomasa, la calidad nutricional y grado de preferencia de 10 leguminosas forrajeras fijadoras de nitrógeno para determinar la viabilidad de ser usadas como abono verde. El trabajo se realizó en el Centro de Investigación Motilonia y en la finca Salguero localizadas en el municipio Agustín Codazzi y Valledupar respectivamente. Se empleó un diseño completamente al azar con tres repeticiones en cada localidad; las variables de respuesta en cada finca se sometieron a un análisis de varianza y prueba de comparación de medias Tukey y para evaluar el grado de preferencia se realizó un análisis de componentes principales. Se observaron diferencias (p<0.05) entre las especies de leguminosas en el contenido de materia seca (MS) y la producción de forraje verde (FV). En el C.I Motilonia el contenido de MS fue mayor en la especie Centrosema molle con un 27.1%, pero la leguminosa Vigna ungiculata LCP 26 presentó la mayor producción con 3.628 kg de MS ha-1 y en la localidad de Salguero el mayor contenido y producción de MS lo presentó la Vigna unguiculata LCP 26 con 38.2% de MS y 6.305 kg de MS ha-1 respectivamente; se presentaron diferencias (p<0.05) en el contenido de proteína y calcio, siendo mayor en la Clitoria ternatea, en Canavalia ensiformis y Lablab purpureus con 23.2 y 4.8% respectivamente. Lo anterior, concuerda con la preferencia por parte de los productores para las leguminosas con mayor producción y calidad nutricional.
Panorama actual de la Diarrea Epidémica Porcina: Etiología, Patogénesis y Diagnóstico
Authors: Sánchez-Álvarez Jesús Aurelio , Franco-Robles Elena
Published: September 2024

Actualmente, las enfermedades gastrointestinales están incluidas entre las principales enfermedades infecciosas de los porcinos, tanto por su frecuencia de aparición como por el costo económico que representan para los productores. En los últimos años, la presencia de diferentes virus entéricos, aunado a la ausencia de vacunas comerciales para su prevención de estos, ha dificultado el control de infecciones entéricas y aumentando el impacto de enteritis víricas en las explotaciones porcícolas. La Diarrea Epidémica Porcina (DEP) produce un cuadro clínico caracterizado por la rápida aparición de diarrea, que se acompaña de vómitos y deshidratación, y puede causar alta letalidad en los primeros días de vida de los lechones, así como retraso del crecimiento en los cerdos de mayor edad. La DEP es ocasionada por un alfa-coronavirus de ARN monocatenario que se replica en los enterocitos lisándolos y necrosándolos lo que conduce a la aparición de los signos clínicos dentro de los primeros 10 días posteriores al contagio. El diagnóstico molecular del virus de la DEP se considera la mejor opción debido a que es altamente sensible y específico ya que detecta la infección en las etapas iniciales y la excreción del virus durante el periodo de la infección y de seroconversión en comparación con técnicas inmunológicas.

Clinical evaluation of CoolSeal - a new, safe, and fast vessel sealing device in total thyroidectomy
Authors: Hansen Mette Vold , Reinke Rasmus , Londero Stefano Christian , Rolighed Lars
Published: October 2024

Objective. CoolSeal is a new vessel sealing system for dissection and hemostasis during surgery. No clinical studies have investigated safety, advantages or disadvantages regarding the use of this device. The aim of the present study was to investigate the safety of CoolSeal and compare it with conventional ligation technique or LigaSure during the total thyroidectomy. We hypothesized that the use of CoolSeal would reduce the operating time and bleeding without complications increase. Study design represents a retrospective cohort study with a tertiary reference center setting.

Methods. We analyzed total thyroidectomy data from January 2021 to June 2023. We recorded patients’ characteristics, surgical information, and postoperative outcome.

Results. We performed 221 total thyroidectomies in the study period. Analysis was restricted to 171 patients operated by only two surgeons. Hemostasis was secured by conventional ligation in 117 patients (68%), LigaSure in 34 patients (20%) and CoolSeal in 20 patients (12%). Median thyroid weight and bleeding were 67 g and 50 ml, respectively. Procedures using LigaSure or Cool-Seal were on larger glands (median 205 g) without increased bleeding (50 ml). Operating time was shortest with CoolSeal (96 min, p=0.003) compared with LigaSure (117 min) or conventional ligation (115 min). Bleeding was reduced with CoolSeal compared with LigaSure (45 vs. 100 ml, p=0.003). With CoolSeal, median hospitalization was one postoperative day, no patients required re-operation. There was no palsy of recurrent laryngeal nerves and no permanent hypoparathyroidism.

Conclusion. In our first clinical experience, CoolSeal was safe and efficient for total thyroidectomy. With a small sample size, we saw a clinical benefit with reduced operating time without post-operative complications increase.

Published: September 2024

The paper aims to aid in developing a monitoring system for surgery patients who have undergone lumbar interbody fusion (LIF). The present body of work functions as a comprehensive analysis of relevant available literature along with our investigation regarding techniques for power delivery; both energy harvesting and wireless power transfer (WPT) alike. In addition, biological considerations are taken into account as they strongly influence the design and testing methodology of an implanted medical device (IMD). This study proposes using inductive coupling as a power delivery method. This was chosen due to the robust nature of the technology, with the IMD being deeply situated and encased in bone and tissue. Three types of receiver coil architectures were explored and designed around the geometry of a polyether ether ketone (PEEK) Extreme lateral interbody fusion (XLIF) Nuvasive Coroent XL interbody cage. With the use of off-the-shelf components, functionality was only attainable for the V3 coil design featured with 0.4 mm wire windings around horizontal and vertical beams present on the implant. The secondary coil was resonantly tuned and optimized for a 141 kHz working frequency. At a 100 mm coupling distance, it was demonstrated that a power delivery load (PDL) of 3.94 mA was able to be induced resulting in a power output of 7.21 mW. The recorded PDLs are capable of powering a high pressure P122 sensor, EFM8BB52 microcontroller, and Ultra-wideband (UWB) data telemetry link, and demonstrate the feasibility of this WPT technique for in vivo monitoring of bone fusion post XLIF surgery.
Development of an IoT-Based Smart Watering System for Monitoring and Increasing Soil Moisture Content in “Tabtim Siam” Pomelo Garden in Pak Phanang District, Nakhon Si Thammarat Province, Southern Thailand
Authors: Thongkhao Kanthawong , Ruang-on Somporn , Tina Fahmida Wazed
Published: September 2024

In Thailand, “Tabtim Siam” pomelo production is essential for domestic consumption and export. Among several environmental factors, soil moisture is the most important factor for citrus plants’ growth and their fruit quality. During the main developmental stages of these plants, the required soil moisture should be above 70% (no water deficit). Therefore, keeping soil moisture at ≥70% in pomelo orchards is crucial. This study developed an IoT-based smart watering system that efficiently monitors soil moisture and assists in maintaining soil moisture at the required level even at a high temperature inside a pomelo orchard in Pak Phanang District, Nakhon Si Thammarat Province, Southern Thailand.
Effect of Ancymidol and Phloroglucinol on the Number and the Quality of Shoots in the Micropropagation of Date Palm (Phoenix dactylifera L.)
Authors: Al-Mayahi Ahmed Madi Waheed
Published: September 2024

The disadvantages of practical date palm micropropagation are tissue browning, low callus proliferation rate, low multiplication efficiency, and vitrification. The aim of the study was to determine the effect of ancymidol (Ancy) and phloroglucinol (PG) on the growth and some biochemical components of the ‘Barhee’ date palm cultured in vitro. The combination of 0.75 mg·l−1 Ancy and 50 mg·l−1 PG was found to be the most effective in terms of callus regeneration rate (89%) and number of shoots (14.3). A reduction in browning was observed in tissues cultured on media supplemented with 0.75 mg·l−1 Ancy in combination with 25 or 50 mg·l−1 PG. The medium supplemented with 0.75 mg·l−1 Ancy and 50 mg·l−1 PG eliminated shoot vitrification. Effective micropropagation was associated with increased carbohydrate and protein content. In this study, the genetic stability of plants obtained by micropropagation was confirmed by DNA-based RAPD fingerprinting. The results may indicate that the micropropagation protocol used in this study was suitable and applicable to the production of genetically stable date palm plants on a mass scale.
Leibniz’ und Kants Anthropozentrierung des Bösen und das neue Böse bei Nietzsche und Musil
Authors: Laux Matthias
Published: September 2024

Leibniz’s metaphysics already justifies evil not only through the normative power of God, assuming that it is simultaneously the omnipotence of reason. For Kant, evil becomes definitively the sole problem of the rational being, human. While for Leibniz, the divine will had organized all practical relations of humans and movements of the physical world in such a way that the practical reason of all individuals is metaphysically constituted and evil is justified, Kant shifts the focus to the practical reason of humans as autonomous subjects. In this paradigm, God loses his metaphysical power, retaining only a moral role. Nietzsche and Musil build upon this context, yet surprisingly, they do not further advance this development. Instead, they reject the power of pure reason, which becomes absolute for Kant. Simultaneously, they draw on God’s metaphysical power over evil to formulate their concept of the new evil that confronts us in the practical contexts of modern life.
Gesundheitsreformen: Mehr Transparenz, mehr Effizienz und mehr Digitalisierung sind notwendig
Authors: Jochimsen Beate
Published: September 2024

The German healthcare system faces a diverse set of challenges including demographics, climate change and insufficient digitisation. The current healthcare reform involves a series of new legislation. The first focus is to overcome the overcapacity of hospitals and beds as well as economic disincentives in the inpatient sector. A second focus is to advance the integrated digitisation across health services. The current inpatient sector is overly quantity-driven, which among other things leads to increasing case numbers due to economic rather than purely medical imperatives. Digitsation legislation seeks to allow full use of electronic medical records. The important thing, however, is the swift implementation of reform.
Demokratie ohne Wachstum und Kultur des Wandels

Democracy in Germany is being challenged like never before in history. Criticism and radicalisation are growing, while acceptance and support are dwindling. There are many reasons for this – not least economic ones. “Growth weakness” is turning into a problem of fiscal sustainability. Economic and political systems are endangered by overburdening. Ways out of this danger can only be found if significant changes can be made in three areas: worst-case scenarios must be included; analysis must go beyond traditional supply-side policies and focus more on questions of distribution and justice; the search horizon for solutions must be expanded in the direction of socio-cultural potentials, with a shift in focus from technical to social innovation. The transformation to sustainable development must be understood as a cultural transformation; this is the only way it will succeed.
Zukunft Deutschlandticket: Verkehrswende, Finanzierung und wohlfahrtsökonomische Wirkung

Published: September 2024

Previous analyses and evaluations of the Deutschland Ticket have generally focused on individual aspects, while an overall and welfare-economic assessment is lacking. On the basis of our own data material, supplemented by new research findings, we attempt to close this gap. The Deutschland Ticket generates benefits that are primarily determined by the consumer surplus and the reduction in external costs of car traffic. The cumulative benefit exceeds the costs of the ticket and generates a net economic benefit of almost two billion euros per year. Against this background, the possibilities for a change in financing are discussed.

Background: Follicle-stimulating hormone (FSH) plays a crucial role in female reproductive function. Body mass index (BMI), a measure of body fat, has been implicated in various health conditions, including reproductive disorders. However, the relationship between BMI and FSH levels in women remains a subject of ongoing research.
Method: This cross-sectional study was conducted on a sample of 200 women of reproductive age at King Faisal Specialized Hospital, Taif City. The study reviewed 200 medical records of women aged 15-50 who reported changes in appetite, excluding those with postmenopausal status, psychiatric disorders, thyroid disorders, immunological diseases, or cancer. Data on demographics, reproductive history, lifestyle factors, anthropometric measurements, FSH levels, appetite changes, and menstrual disorders were collected using a pre-designed checklist. Statistical analysis was performed using SPSS version 26, employing chi-square tests, Mann-Whitney U tests, and Spearman's correlation coefficient.
Results: Over half (66%) of the participants were overweight or had mild-to-moderate obesity, with a mean BMI of 28.54 ± 6.93 kg/m² and FSH level of 10.77 ± 14.49 IU/l. No significant correlation was found between BMI and FSH levels (r = 0.13, p-value = 0.085). However, a positive correlation existed between FSH levels and participant age (r = 0.35, p-value

An electrical conductivity database for continuum flow in a [Formula: see text] atmosphere over a 70° spherecone was created using the Data Parallel Line Relaxation Code computational fluid dynamics software to inform development of future magnetohydrodynamic subsystems at Venus and Mars. Sixteen freestream conditions were considered at Mars with atmospheric relative velocities from 5 to 8 km/s and altitudes between 20 and 80 km. Sixteen freestream conditions were considered at Venus with atmospheric relative velocities from 9 to 12 km/s and altitudes between 85 and 115 km. Results indicate that the total electrical conductivity in the flow volume always increases as velocity increases. At low velocities, the electrical conductivity is higher at high altitudes whereas, at high velocities, the electrical conductivity is higher at low altitudes. Three of the 80 km altitude computational fluid dynamics solutions show good agreement with direct simulation Monte Carlo results. In general, computational fluid dynamics predicts thinner shocks, higher electron number density, and similar vibrational temperatures to direct simulation Monte Carlo. The magnetohydrodynamic force was calculated at both Mars and Venus. Results indicate there may not be sufficient control authority to use magnetohydrodynamics as a trajectory control mechanism at Mars without artificially increasing the electrical conductivity of the flow, but there may be appreciable control authority for a drag-modulated aerocapture at Venus.
Gauss Equations for Local Action-Angle Orbital Elements in Cislunar Space
Authors: Peterson Luke T. , Scheeres Daniel J.
Published: October 2024

To track orbits in cislunar space, predict where they will naturally move over time, and identify where unbounded trajectories come from, one may consider local action-angle orbital elements—coordinates that relate a spacecraft state to specific trajectories and exist in approximately integrable regions of the Earth–moon circular restricted three-body problem (CR3BP). As local action-angle elements are a semi-analytical analog to two-body orbital elements, the theory is extended to allow for the study of arbitrary perturbations to the dynamics. Namely, we derive Gauss equations for an arbitrary perturbing acceleration—continuous or discrete—to the CR3BP. Examples for continuous thrust and impulsive [Formula: see text] are provided in cislunar space, i.e., around Earth–moon [Formula: see text] in the CR3BP. Strategies for instantaneous maneuver design and transfers between quasi-periodic orbits and manifolds are developed.

Published: September 2024

The court summon is the first spearhead of the entire trial process, especially for the civil cases. Court summon has an essential role, even the summon process may decide the legitimation of a trial that conducted by the judge. The court summon is conducted in order to inform the parties when they should appear before the judge. It becomes important due to its impact to the parties’ life fate, either its right over goods or its legal status on a family. Therefore, the laws shall ensure that every person shall know whenever their rights being challenged before the court. In civil cases the court summon is regulated under Article 390 HIR (718 RBg), which is one of its kind is known as public summon. The legal basis to conduct the public summon in last 170 years has not been changed, only public summon in certain case that amended, such as in divorce case. Even then, the change does not really change the summoning process, the summoning still conducted by using a announcing paper that put in the government building and announcing through conventional media mass such as newspaper, radio or television. However nowadays, this kind of media has been left by the people, their popularity has been stolen by the internet like youtube, facebook, Instagram and etc. The Supreme Court (Mahkamah Agung, hereafter as “MA”) shall adapt to this era, MA shall re-innovate the way public summon conducted in last 170 years, by using the innovation of the 21th century which is the “internet”, by using the “Electronic Public Summon”.

Quando a linguagem trai o sentido: Honneth e Ricouer leitores de Hegel
Authors: Costa Danilo Vaz Curado R. M. Costa
Published: October 2024

O presente artigo defenderá o argumento que dois grandes filósofos e pensadores da atualidade, Axel Honneth e Paul Ricouer, ao elaborarem no seio de seus projetos filosóficos a reconstrução da teoria do reconhecimento de Hegel, extrapolaram os limites e margens da tensão existente entre o espírito e a letra da filosofia, em geral, e da hegeliana, em especial, de modo que em suas interpretações a linguagem trai o sentido, ou seja, da letra não se segue o espírito.

Restoring the permeability of peat soil using a mixture of sand and bio-grouting techniques made from bacteria aimed to determine the effect of adding 5% sand by weight of dry soil and bacteria on the permeability of peat soil. Peat soil is a problem that is often encountered in the world of construction. Peat is a type of soil formed from the accumulation of half-decayed plant remains which causes it to have a high organic matter content.
The research testing method refers to ASTM (American Society for Testing and Materials) procedures and SNI. Preliminary testing, namely testing the original soil moisture content, testing the original soil specific gravity, and testing standard compaction (proctor test). Meanwhile, permeability testing was carried out using the falling head method. The original soil was taken at the location of Buana Makmur Village km 55, Dayun Sub District, Siak Regency, namely in the form of sand 5% of the dry weight of the soil, additional ingredients in the form of bacteria and CaCl2 and Uruea.
Based on the results of testing the physical properties of the original soil, it is known that the soil in Buana Makmur Village, km 55, Dayun Sub District, Siak Regency, is an original soil type with a water content of 407.5% and a specific weight (Gs) of 1.3 gr. Based on the results of the permeability test conducted, mixing 5% sand and adding 25% bacteria had the lowest permeability coefficient value compared to the original soil and sand mixed soil which had a permeability coefficient of K20oc = 1.166x10-3cm/second.

Published: September 2024

The doline water hydrochemical study was conducted in the Gunungsewu karst area, Yogyakarta Special Region. The hydrogeological survey followed by doline water sampling was carried out in the Panggang and Wonosari-Baron Hydrogeological Subsystems. Ten selected doline water samples were taken, each in the dry and rainy season, for further physical/chemical testing in the laboratory. Research analysis includes hydrochemical analysis of several parameters such as pH, TDS, EC, major and minor ions content and assisted by difference and variability tests statistical analysis. The hydrochemical variations of doline water in the study area generally did not show any spatial variations, except for the EC parameter. Temporal/seasonal hydrochemical variations are apparent, as evidenced by differences in many variations of TDS, EC, major ions (Ca2+, Na+, K+, HCO3-, Cl-), and minor ions (sulfate and nitrate). In the dry season, the hydrochemical facies generally develop as Ca, Na-bicarbonate facies, while in the rainy season, doline water typically has Ca-bicarbonate facies. The hydrochemical of doline water may be influenced by groundwater.
