Lamellar cell death and proliferation are associated with restricted ambulation and preferential weight bearing in a model relevant to supporting-limb laminitis
Authors: Engiles Julie B. , Stefanovski Darko , van Eps Andrew 
Published: February 2025

Abstract

Objective
To examine the effects of prolonged preferential weight bearing (PWB) and reduced ambulation (RA) on hoof lamellae using a nonpainful in vivo experimental model.

Methods
12 healthy Standardbred horses were housed in stocks continuously for 92 hours. A platform shoe was placed on 1 forelimb in the PWB group (n = 6) to increase the load on the supporting limb (SL) by approximately 10% bodyweight, whereas the RA group (n = 6) had normal weight bearing. Archived healthy horse (n = 8) samples were used as controls. Histomorphometry and histochemistry (terminal deoxynucleotidyl transferase dUTP nick-end labeling [TUNEL], caspase-3, and targeting protein for Xenopus kinesin-like protein [TPX-2]) results were analyzed using mixed-effects linear regression.

Results
Lesions in multiple limbs from the PWB and RA groups included secondary epidermal lamellae elongation, cell death (mostly TUNEL-positive, caspase-3–negative parabasal keratinocytes), and basal cell proliferation (TPX-2 positive). Lesions were most severe in the PWB group SL, with significant increases (vs control) in mean (95% CI) primary epidermal lamellar (PEL) length (3.7 [95% CI, 3.5 to 3.8] mm vs 3.2 [95% CI, 2.9 to 3.4] mm; P < .001), secondary epidermal lamellae length (281 [95% CI, 235 to 327] µm vs 185 [95% CI, 155 to 215] µm; P < .001), TUNEL count (45 [95% CI, 30 to 60] vs 4 [95% CI, 2 to 5] positive cells/PEL; P < .001), and TPX-2 count (116 [95% CI, 46 to 186] vs 5 [95% CI, 3 to 6] positive cells/PEL; P < .002). Both TUNEL- and TPX-2–positive cell counts were increased in the RA group forelimbs versus control (P < .05).

Conclusions
Restriction of normal ambulation, even in the absence of increased weight bearing, caused lamellar parabasal keratinocyte death and structural derangement of lamellae.

Clinical Relevance
Promoting ambulation, not just limb load relief, may be a critical strategy for preventing SL laminitis.
A 2-D Extension of the Trend Concept Applicable to Images, Surfaces and Space-Time Signals
Authors: Padet Jacques 
Published: February 2025

Abstract
The analysis of highly irregular processes is often based on the search for a trend, an average curve representing the general pattern of the phenomenon observed. This concept seems intuitive, but determining it objectively raises a number of problems. As the moving average method is one of the most widely used for finding one-dimensional trends, we propose here to extend it to two-dimensional data sets, and to study some of the properties of these 2-D moving averages. We then show that they can be used to detect characteristic observation windows (uniform or self-adaptive), leading to structural trends in the analyzed signal. The method is first applied to functions f(x,y) whose variables have the same physical dimension (length,…). It is then generalized to cases of different dimensions (e.g. space-time signals). Applications cover a wide range of fields (turbulent structures in fluid mechanics, image analysis, characterization of surfaces, optimization of an observation process, multi-scale modelling, ...).

Published: February 2025

Abstract
Prefabricated Reinforced Concrete (PRC) frame structures designed and executed in the pre-1989 period in Romania, occupy a leading spot in the list of industrial, commercial, social and cultural buildings. In this research study, a structure of this type is analyzed. In the introductory part of the study, the types of PRC frame systems specific to seismic zones and their component elements are highlighted. The second part shows the main structural deficiencies of the PRC frame structures required to severe earthquakes. In the following chapters, the dynamic analysis related to the studied structure is developed, as well as a verification of the lateral stiffness. Thus, it was found that the PRC structure develops lateral displacements higher than the admissible limit. In these conditions, some solutions are proposed for retrofitting the structural system using vertical steel braced frames, shear walls, steel-RC composite columns and steel beams on the bay direction.
Methods of Assessing the Thermal Performance of Curtain Wall Facades. Specific Energy Audit Problems
Authors: Pescaru Radu-Aurel , Dumitrescu Laura , Baran Irina , Bliuc Irina 
Published: February 2025

Abstract
To achieve a significant national reduction of greenhouse gas emissions in the construction sector, the Romanian government has aligned national policies with European regulations on the energy efficiency of buildings. For that, when constructing new buildings or renovating existing ones, the criteria associated with the concept of nearly zero-energy building (nZEB) are respected. Achieving this objective involves knowing the tools for evaluating the energy performance of the building envelope, considering the important weight it plays in the total energy consumption for normal use. The purpose of this paper is to highlight the possibilities of designers and energy auditors for buildings to evaluate, with a satisfactory degree of accuracy, the energy performance (EP) of curtain wall facades using the calculation methods proposed in SR EN ISO 12631:2018. A study on the influence of some representative parameters on thermal transmittance, carried out on a generic curtain-type facade element, supports those involved in the process of optimizing the solutions for new buildings or the renovation of existing ones.

Published: February 2025

Abstract
Low water quality is an enduring problem in water management and has global importance due to the increasing use of water by the world’s growing population. Based on climate change trends, the availability of water of acceptable quality will increasingly be a hot topic. The main objective of this work was the compilation and validation of a water quality model for the river Elbe (Czech: Labe) for the prediction of water quality under different scenarios (impact of point and nonpoint sources; effect of climate change). The assessment of water quality in the Elbe catchment is extremely important because the Elbe is one of the most important rivers in Europe. We focused on the water quality in the Czech part of the river Elbe, which was simulated and analysed with the QSim water quality simulation model. The model was applied from the Srnojedy weir to the Hrensko at the Czech-German border (river km 961 to km 726), comprising a cascade of 23 impoundments. Based on the measured input parameters for 2010-2015, the water residence time, oxygen conditions, and nutrients were simulated and validated. The model’s results strongly agree with the measured data from the monitored period. The proposed model can, therefore, be used to simulate the development of pollution or climate change effects in this watercourse, allowing for the prediction of water quality under different scenarios.

Published: February 2025

Abstract
To increase the process stability and improve the product quality in the sheet hydroforming with die process, it is crucial for identifying and analyzing the dependence of forming pressure on process parameters. The effects of process parameters (blank holder force, frictional condition) on the forming fluid pressure were thoroughly studied experimentally. The main objective is to establish a relationship between the forming fluid pressure and several factors such as blank holder force and friction between die and sheet. The results demonstrate that the maximum fluid pressure increases with increasing blank holder force and friction. Finally, this relationship aims to support calculations and design data and provide control during the SHF-D process.
Effect of Hybrid Composite Electrode (Cu/Cr/Wc/Ag) on Surface Integrity of Stainless Steel 304l Machined by EDM
Authors: Abdulwahhab Ahmed Basil , Ibrahim Abbas F. 
Published: February 2025

Abstract
Electrical Discharge Machining (EDM) is a modern technique extensively utilized across various industries to eliminate material using electrical discharges. Within the realm of EDM, a key obstacle involves identifying appropriate electrode materials capable of withstanding elevated temperatures and effectively eroding material from workpieces. Composite electrodes are becoming more commonly employed to tackle this issue, as a result of their exceptional electrical and thermal properties. The performance of a composite electrode that has been specifically improvement with (Cu-3%Cr-0.5%WC-1%Ag) is evaluated in this study using the stir casting technique. The investigation utilized stainless steel 304L as the workpiece material, and the performance of the composite electrode was evaluated against traditional pure copper electrodes. The results indicate that composite electrodes can decrease electrode wear and increase machining efficiency. The tool wear rate (TWR) for the composite electrode decreased to 0.0398 gm/min with a current of 10 A and a pulse-on time of 50 µs, along with a pulse-off time of 50 µs. In contrast, under the same conditions, the copper tool exhibited a TWR of 0.514 gm/min. The composite electrode achieved the highest material removal rate (MRR) at 59.7917 mm3/min, surpassing the copper electrode which had the lowest MRR at 54.5588 mm3/min. Additionally, the Surface Roughness (SR) of the composite electrode was measured at 3.253 μm, lower than the 3.967 μm of the pure copper electrode. These findings suggest that composite electrodes could serve as a viable substitute for conventional EDM electrodes.

Рассматриваются особенности роста и развития ландыша майского (Convallaria majalis L.) сорта Берлинский и популяции, взятой из природных местообитаний (Московской области окрестности города Домодедово, молодой осинник). В ходе исследований было выявлено, что ландыш сорта Берлинский обладает наибольшей энергией прорастания, чем растения из природной популяции. Фенологические наблюдения показали, что между сортовыми и дикорастущими растениями в первый год нет особых различий, только вегетационный период подмосковной популяции началась раньше на 3 дня и составила 142 дня, а у сортового всего 139. Однако у сортового ландыша было отмечено большее количество цветущих особей. Процент побегов, образовавших соцветие, с возрастом увеличивался, только двулетние растения (при вегетационном размножении) совсем не цветут. Изученные биометрические показатели были несколько выше у растений из природной популяции из Подмосковья, по сравнению с ландышем сорта Берлинский.
The article discusses the features of the growth and development of May lily of the valley (Convallaria majalis L.) of the Berlin variety and a population taken from natural habitats (Moscow region, the vicinity of the city of Domodedovo, young aspen). In the course of research, it was revealed that the and Berlin lily of the valley has the highest germination energy than the natural population. Phenological observations showed that between the varietal and wild populations in the first year there are no special differences, only the vegetation period of the Moscow Region population began earlier by 3 days and amounted to 142 days, and in the varietal only 139. However, varietal lily of the valley showed a greater number of flowering individuals. The percentage of shoots that formed an inflorescence increased with age, only biennial plants (during vegetative propagation) did not bloom at all. The studied biometric indicators were slightly higher for plants of the natural population from the Moscow region, compared with the lily of the valley Berlin (in the phenophase flowering).

Sampah merupakan masalah serius yang dihadapi banyak tempat di Indonesia. Masalah sampah masih belum ditangani secara memadai karena adanya kesenjangan antara kapasitas pengelola sampah dengan volume sampah yang dihasilkan. Selain itu, kurangnya kesadaran dari masyarakat untuk meengelola sampah dengan baik menjadi kendala utama. Lingkungan Topa Pantai merupakan salah satu wilayah di Kota Baubau yang tak luput dari persoalan sampah. Tujuan dari kegiatan pengabdian ini adalah menumbuhkan sikap peduli lingkungan kepada masyarakat melalui program pesan berantai yaitu pengelolaan sampah lingkungan agar bersih, nyaman, sehat, asri dan juga indah sebagai upaya mewujudkan pembangunan berkelanjutan. Kegiatan dilaksanakan dalam bentuk sosialisasi, pelatihan dan edukasi yang dilaksanakan di lingkungan Topa dan melibatkan masyarakat setempat (ibu-ibu rumah tangga) dan siswa SD Negeri Topa sebagai mitra. Kegiatan dilaksanakan melalui beberapa tahapan yaitu observasi untuk mengetahui permasalahan mitra, persiapan dan perencanaan kegiatan, implementasi dan evaluasi. Kegiatan sosialisasi dan pelatihan diikuti oleh mitra masyarakat (ibu-ibu) berjumlah 10 orang sedangkan untuk siswa SD Negeri Topa kegiatan pengabdian dilaksanakan dalam bentuk sosialisasi dan edukasi dan diikuti oleh 45 siswa sebagai peserta. Kegiatan ini telah memberikan dampak positif terhadap mitra berupa pengetahuan dan keterampilan tentang pengelolaan sampah. Hasil ini dapat dilihat dari hasil evaluasi 1) mitra (ibu-ibu rumah tangga) telah mampu mngelola sampah dengan baik yang ditunjukkan dengan adanya produk yang dihasilkan dari pengelolaan sampah rumah tangga seperti pupuk organik dari cangkang telur dan kerajinan dari limbah plastik; 2) mitra (siswa SD Negeri Topa) telah memiliki pengetahuan tentang sampah pengelolaan sampah dimana 84% (38 siswa) telah memiliki pemahaman yang baik dan 16% (7 siswa) juga menunjukkan pemahaman yang cukup baik terutama dalam hal memilah sampah sesuai jenisnya dan dampak dari pengelolaan sampah. Berdasarkan hasil evaluasi maka diperoleh kesimpulan bahwa pelaksanaan kegiatan pengabdian berjalan dengan baik dan lancar sesuai dengan tujuan yang teelah ditetapkan.
