La major part de restes de fauna que es recuperen en els jaciments arqueològics són deixalles del processament i del consum de productes carnis que van generar les persones que van viure a l’assentament en qüestió. Per tant, el seu estudi aporta informació primordial sobre l’alimentació del grup humà que va generar aquestes deixalles. Tenint en compte aquestes consideracions, amb aquest article volem mostrar les eines que té l’arqueozoologia per estudiar l’alimentació, a partir de la presentació de diversos casos d’estudi que ens permetran incidir en diferents aspectes vinculats amb la dieta càrnia en època romana. L’estudi de la representació taxonòmica i anatòmica, l’estimació dels perfils de mortalitat i l’anàlisi de les pautes de fracturació i de les termoalteracions ens han permès documentar les espècies animals que van ser consumides en vil·les i ciutats, les porcions de carn que van ser adquirides en un centre terrisser, la producció de productes en conserva que es va dur a terme en una ciutat i les diferents tècniques culinàries que van ser utilitzades en diversos assentaments per coure els aliments.

Published: December 2024

Pancreatic cancer ranks as the 12th most common cancer globally, responsible for 7% of all cancer-related deaths. Patients with
unresectable tumors have only a 20% chance of surviving one year; patients diagnosed at stage III or IV of the disease expect only
4 to 6 months to live. This retrospective study evaluated the impact of deuterium-depleted water (DDW) on the median survival
time (MST) of 93 patients with pancreatic cancer. Without altering their conventional treatments, the patients’ daily fluid intake
was entirely replaced with 1.5 to 2 liters of DDW to lower deuterium concentration in their bodies. The MST from diagnosis to the
end of observation was 21.5 months (95% CI: 12.6–30.3). Notably, there was a pronounced, though not statistically significant
(p = 0.215), difference in MST between genders. The MST for female patients was 37.5 months (95% CI: 8.8–66.1), compared to
17.1 months (95% CI: 12.1–22.1) for male patients. Four case studies are presented, highlighting significantly longer survival
times than previously reported in the literature. These findings suggest that deuterium depletion, when combined with standard
treatments, may improve survival outcomes in advanced-stage pancreatic cancer more effectively than targeted therapies or
combination treatments alone.

Published: December 2024

Objective: This study explores the anatomical variations and characteristics of the lateral thoracic artery (LTA) and its perforators through thoracic computed tomographic angiographies (CTA) and cadaveric dissection, aiming to enhance surgical planning and patient outcomes.
Materials and Methods: Data were recorded for both thoracic CTA patients (n = 40) and soft cadavers (n = 13) for subsequent retrospective analyses of biological sex, age, body mass index (BMI), LTA characteristics (length, diameter, origin, number of perforators, number of lymph nodes), and locations (rib level and distance from the pectoralis major, latissimus dorsi, and acromioclavicular joint).
Results: Average LTA parameters for thoracic CTAs were 89.6 millimeters in length from origin and 2.1 millimeters in diameter, while cadavers were 117.0 millimeters in length and 2.3 millimeters in diameter. At least 1-2 cutaneousperforators and 1 proximal lymph node were found across both thoracic CTAs and cadavers. No significant differences were observed between the left and right sides for both groups. On average, 73.8% and 66.4% of LTAs from thoracic CTAs and cadavers, respectively, originated from the axillary artery.
Conclusion: This knowledge is crucial for surgical planning, both to minimize damage to the LTA and ensure the inclusion of its perforators and proximal lymph nodes in the lateral thoracic region. The researchers recommend lateral thoracic artery perforator flap harvest between the lateral border of the pectoralis major and the anterior border of the latissimus dorsi, specifically above the 3rd-6th ribs, which is correlated to the length of LTA at 89.6-117 millimeters from origins.
Comparative Evaluation of Phacoemulsification with Goniosynechialysis and Phacoemulsification with Viscogonioplasty in Angle-Closure: A Randomized Clinical Trial
Authors: Asanathong Dechathon
Published: December 2024

Objective: To compare the effects of phacoemulsification with goniosynechialysis (GSL) versus viscogonioplasty (VGP) on intraocular pressure (IOP) reduction and medication use in angle-closure patients.
Materials and Methods: This randomized controlled trial at Sisaket Hospital, Thailand, from November 2021 to May 2024, enrolled patients with angle-closure and cataracts. Group 1 underwent phacoemulsification with GSL, and Group 2 with VGP. Visual acuity, IOP, and medication use were assessed before surgery, then at 1 week, 1 month, 3 months, and 6 months post-surgery.
Results: 58 eyes were included: 30 in Group 1 and 28 in Group 2. The average age was 67.16±9.65 years in Group 1 and 67.78±7.38 years in Group 2 (P=0.79). Baseline IOP was 24.31±12.34 mmHg in Group 1 and 24.92±12.50 mmHg in Group 2 (P=0.85). After 6 months, IOP decreased to 12.84±2.88 mmHg in Group 1 and 13.62±4.28 mmHg in Group 2 (P=0.40). Glaucoma medications decreased from 3.47±0.94 to 1.93±1.20 in Group 1 and from 3.54±0.58 to 1.46±1.37 in Group 2 (P=0.17). Hazard ratio: 4.29 (P=0.066, 95% CI: 0.91–20.18).
Conclusion: Both Phaco-GSL and Phaco-VGP significantly reduce IOP, with no significant difference in efficacy. Phaco-GSL may sustain IOP reduction longer in extensive PAS cases. However, the short follow-up period and lack of postoperative gonioscopy are limitations. Longer-term studies with larger sample sizes are needed to confirm these results.

Authors: Prasitviset Phatcharawan , Pisarnturakit Pongthep , Ratanawichitrasin Adune
Published: December 2024

Objective: Delays between diagnosis and breast cancer surgery may raise concerns about tumor progression. Tumors of the same size should exhibit same proportions of N staging. We aimed to evaluate the impact of time to surgery (TTS) on the proportion of metastatic axillary lymph nodes (N-Staging), controlled by tumor size.
Materials and Methods: A cross-sectional study of primary breast cancer patients treated between October 2021 - December 2022 at the Division of Head Neck and Breast Surgery, Siriraj Hospital, Thailand examined the association between lymph node staging and TTS, stratified by primary tumor size. Patients with neoadjuvant therapy, DCIS, or underwent excisional biopsy were excluded.
Results: Of 424 patients, mean age 60.95 years, had an average tumor size 17±13.38 mm, and 20.8% LNs metastasis. The mean TTS was 7 ± 3.11 weeks. The proportion of + LNs patients stratified by tumor size was 10.6% for T1, 34.56% for T2, and 43.75% for T3 lesions. There was no significant difference between TTS and the proportion ofN-staging for all T2 and T3 tumors. In contrast, a significant finding was observed among T1 tumors. Axillary nodal metastasis became more advanced as TTS increased (p-value = 0.022); and increased N2 and N3 nodal staging was noted in patients with delayed surgery. No significant additional differences were found concerning breast cancer subtype, pathological grading, or lympho-vascular/perineural invasion.
Conclusion: Increasing TTS was significantly associated with more advanced N staging. This finding highlights the need for timely intervention in early breast cancer, particularly in T1 tumors.

Avrupa'da Popülist Krizler ve Huzursuzluk: Sağ Popülist Söylemde Güvenlikleştirme ve Yeniden Yaratılan Kırılganlıklar
Authors: Özdemir Veli , Kaçar Aşcı Fatmanur
Published: December 2024

Popülist söylemlerde güvenlik, esas olarak sıradan insanların kimliği ve bu kimliğe yönelik elitlerin dile getirmediği tehditler tarafından şekillendirilir. Popülist söylemlerde güvenlikleştirme dışlama siyaseti ve siyaset kurumunu etkisiz hale getirmeyle bağlantılıdır. Halka veya halkın kimliğine/kültürüne yönelik varoluşsal bir tehdit ancak popülist aktörün kasıtlı olarak saldırgan bir siyasi üslup kullanmasıyla önlenebilir ve bu üslup popülist aktörlerin kendileri tarafından popülist aktörün arkasında toplanmak için varoluşsal bir krize ihtiyaç duyulduğuna işaret eden bir aciliyet duygusuyla şekillendirilir. Ancak popülist söylemlerde güvenlikleştirme, Kopenhag Okulu'nun elitist ve yukarıdan aşağıya bir süreç olarak gördüğü geleneksel güvenlikleştirme yaklaşımına tam olarak uymamaktadır. Nitekim popülist söylemlerde güvenlikleştirme yukarıda aşağıya ve aşağıdan yukarıya doğru olarak iki yönlü ortaya çıkmaktadır. Popülist söylemlerde güvenlikleştirme geleneksel güvenlik aktörlerini ve devlet elitlerinin otoritesini sorgulamakta ve başta siyasi elitler olmak üzere geleneksel kurumları halka tehdit olarak tanımlamaktadır. Bu çalışma, Avrupa'daki sağ popülist partiler arasında yer alan Almanya için Alternatif Partisi (AfD), Özgürlük Partisi (PvV) ve Ulusal Birlik Partisi (RN)’nin mültecileri halkın güvenliğine yönelik nasıl tehdit olarak tasvir ettiklerini incelemektedir. Çalışmanın dönemi olarak 2017-2022 yılları arasındaki seçim kampanya görselleri ve söylemleri seçilmiştir. Bu çalışmanın temel argümanı, sağ popülizmin, korunmaya ihtiyacı olduğu iddia edilen halka karşı popülist liderlerin söylem ve görsellerle hitap etmesiyle ayırt edilen ve süreklilik arz eden bir güvenlikleştirme tarzı olarak anlaşılabileceğidir. Ayrıca popülist güvenlikleştirme süreçleri çift yönlü bir olgu olduğu için mülteci sorununa siyasi bir çözüm bulunmasına katkıda bulunmamakta, aksine söz konusu ülkelerin toplumsal ve siyasi güvenliğini etkileyen yeni krizler ve kırılganlıklar yaratmaktadır. Bu bağlamda popülizmin farklı karakterizasyonları, güvenlikleştirme teorisi ve popülist söylemlerde güvenlikleştirme süreçleri açıklanmış, sağ popülist partilerin mülteci meselesini nasıl güvenlikleştirdiği konusu Müslüman ve gayrimüslim mülteciler örneği üzerinden analiz edilmiştir.

Published: December 2024

Teachers in an elementary school located at Arcamanik, Bandung, experienced anxieties when speaking in front of audiences. The study aims to identify teachers' anxieties about public speaking training, evaluate how the training alleviates the anxieties, and assess its impact on teachers' public speaking performance. Qualitative approach is employed in this research by using interviews and observations with ten participants: an English teacher, three classroom teachers, and subject-specific teachers in Indonesian, tahfidz (Qur'anic memorization), Arabic, mathematics, and two Islamic religion teachers. The training was conducted at the beginning of the semester to provide sustained professional development. The findings reveal that there are three categories consisting of new comers, old comers and gender. New comer teachers show a significant growth even more they could eliminate speaking doubts, avoiding negative words, clearer speaking, confidence, more understandable, and engaged in communicating more effectively. Secondly, the old comer teachers tend to be steadier and calmer but have a fast-thinking proficiency in making solutions. Lastly, it seen from gender. Female teachers use public speaking theory the most as compared to male teachers who tend to be more ignorant. All the growth stemmed from the school-facilitated training equipping them for various roles – not only as classroom facilitators but also as service providers interacting with parents and at school event. Researchers recommend holding frequent public speaking workshops to assist teachers in overcoming their speaking anxieties. This can boost confidence and help participants communicate more effectively. Everyone can benefit from practice and tips in a confidential environment.

Authors: Divinsky Boris V. , Fomin Vladimir V. , Lazorenko Dmitriy I.
Published: December 2024

In this paper, a comparison of the wind waves parameters calculations in the Black and Azov seas, using two common spectral wave models: DHI MIKE 21 SW and SWAN was made. The fields of the wind waves main parameters (wave heights, periods, directions of propagation) were obtained for a climatic period of time from 1979 to 2018. Comparison of the calculation results shows that with the accepted model settings, the SWAN model, compared with MIKE, overestimates the values of wave heights with weak and moderate waves and underestimates with the extreme ones. Estimation of the maximum wave heights on the Black Sea, possible once in a given number of years, performed on two different models, was made. It showed that for the conditions of the Black Sea the difference between the calculated values of significant wave heights of rare frequency for the MIKE and SWAN models does not exceed 12%. The maximum significant wave heights, possible once in a hundred years, in the Black Sea can reach 11-12 m.
Fabrication of Porous TiO2 with Aligned Pores Using Tert-Butyl Alcohol Based Freeze Casting
Authors: Lee Eui Seon , Oh Sung-Tag
Published: December 2024

The effect of freezing conditions on the pore structure of porous TiO2 fabricated using a freeze casting process with tert-butyl alcohol slurry was investigated. The raw powder was heat treated to manufacture a porous body with stable shape by suppressing volume change induced by the phase transformation of TiO2 powder. The XRD analysis result indicated that the anatase phase fraction in the raw powder could be converted to 98.6% rutile phase by heating it at 800°C for 30 min. Porous TiO2 ceramics with unidirectionally aligned pore channels were prepared by freezing tert-butyl alcohol slurry containing 10 vol% TiO2 powder under different freezing temperatures of -20, -30 and -40°C, respectively. After removing the frozen tert-butyl alcohol by sublimation in vacuum, the green samples were sintered at 1100°C for 4 h in air. The porous body contains directional pores with a size of approximately 30 µm, and a hexagonal pore shape corresponding to the crystal structure of tert-butyl alcohol was observed in the cross-section of the pores. Small pores were observed at the bottom part of the porous body near the Cu plate where the solidification heat was released, but relatively large pores were present at the upper part. Both microstructure observation and pore size distribution indicated that the pore size and the strut thickness increased significantly with increasing freezing temperature. The change in pore characteristics was explained as being mainly due to the difference in the solidification behavior of the slurry and the rearrangement of the solid powder.

Valuable metals contained in LIBs are typically recovered through processes such as leaching, precipitation, and solvent extraction. However, these recycling processes require large amounts of sulfuric acid and caustic soda, resulting in the generation of significant volumes of Na2SO4 waste solution. In order to solve this problem, recent research has focused on using bipolar membrane electrodialysis (BMED) technology to split Na2SO4 and simultaneously recover H2SO4 and NaOH. This study investigated the process of recovering H2SO4 and NaOH from Na2SO4 solution using BMED in a threecompartment cell under constant current conditions. The study evaluated the effects of current density, initial Na2SO4 concentration, and initial H2SO4 and NaOH concentrations. Recovery of H2SO4 and NaOH, current efficiency, energy consumption, and process time were analyzed to determine optimal conditions. Under optimal conditions (1.30 M Na2SO4 solution at 360 A/m²), the recovery of H2SO4 and NaOH were 77.35% and 75.18%, respectively. Energy consumption was 1.43 kWh/kg, with current efficiencies for the acid and base of 51.1% and 49.7%, respectively.
Enhanced Rate Performance of Supercapacitor Electrode Using Hydrophilic Porous Carbon Synthesized from Polyvinylidene Chloride-Resin with CuO and Tetrahydrofuran
Authors: Hong Leejin , Chun Sang-Eun
Published: December 2024

Carbon materials used as an electrode for aqueous supercapacitors should be synthesized with a porous structure and hydrophilic properties to facilitate the adsorption and desorption of electrolyte ions for charge storage. To enlarge the specific surface area, the porous morphology should contain micropores (diameter < 2 nm). Mesopores (diameter: 2 – 50 nm) should also be present for facile ionic transport. Hydrophilic carbon can be achieved by introducing hydrophilic functional groups on the surface. Here, hydrophilic porous carbon was synthesized by mixing a polyvinylidene chloride (PVDC) resin precursor with copper oxide (CuO) and tetrahydrofuran (THF), followed by heat treatment at 750°C. CuO acted as a template during the heat treatment, creating large mesopores. The generated HCl from PVDC combined with CuO to form CuCl2, contributing to the micropore formation. THF played a role in introducing hydrophilic functional groups on the carbon surface, to promote the adsorption of aqueous electrolyte ions. The activated carbon synthesized using CuO and THF exhibited a specific capacitance of 90 F g-1 at a scan rate of 5 mV s-1 in 0.5 M K2SO4 electrolyte. The synthesized activated carbon demonstrated excellent rate capability, retaining 82% of its capacitance at 10 times faster charging rate (50 vs. 5 mV s-1).

Estimation of debris flight trajectories of roof cover from low-rise buildings
Authors: Mejorin Angela , Kopp Gregory A.
Published: December 2024

During windstorm events buildings can represent both wind-borne debris source and target elements. Roof cover can fail and be blown away, impacting the surrounding construction, reaching significant distances. Analytical models to calculate debris trajectories generally consider the flight to occur in uniform flow. These models are, therefore, not considering source building aerodynamics, yielding results that can be significantly overestimated. This paper defines Udebris, the equivalent uniform wind speed that leads to the analytical solutions in roof cover flight assessment that matches the available datasets that considers source building aerodynamics. To calculate Udebris, the concept of response time is introduced: t* is a parameter that physically captures the tendency of debris elements to fly with the wind gust. The identification of these times, typical for each roof cover type, leads to a selection of a gust factor, G, to account for the debris response. Roof/wake factors (FR) are also used for Udebris calculation, based on roof cover type, locations on the roof, neighborhood settings. These last factors are estimated based on t*, on the boundary layer that develops on the source building roof slope, and on considerations about turbulence effects. A Monte Carlo simulation-based approach for estimating roof cover element flight trajectories is, therefore, presented and validated against experimental datasets. The results indicate alignment with experimental observations, underscoring the potential utility of this approach for dealing with wind-borne debris issues in disaster preparedness, building technology, and structural design.

Introduction

Tech-enabled alternative micro-finance promotes income equality in growing BRICS and Austria across financial crises and pandemics. Are financial access and digital skills equally economically valuable? Our study uses inputs: Human Capital, Alternative Micro-finance, Digitization, Governance, and Entrepreneurship, GDP, inflation, population growth, pandemics, and economic crises using the global 2000–2022 to explain income equality using SWIID Gini disposable and market income index as outputs.

Methods

The study uses Principal component analysis for reducing data dimensionality and collinearity. The study uses OLS, Dynamic Mixed Model, and random forest tree, a machine learning technique, as models to model digitally enable micro-finance.

Results

RFT model diagnostics consistently were better than OLS and GMM. Reduced income inequalities resulted from public and private infrastructure investments, government policy interventions to fight pandemics, economic crises, and conflicts, as well as from expansion in GDP.

Discussion

The study concludes that digitally enabled micro-finance plays a crucial role in reducing income inequalities, particularly during times of crisis. Key policy implications include the need for government support in digital infrastructure to enhance financial inclusion. By pooling their resources, the BRICS block can empower micro-finance organizations to ameliorate disruptions from COVID-19 and economic crises.

Published: December 2024

Introduction

Effective monitoring and evaluation of floodwaters are essential for disaster prevention and mitigation. The flood inundation range can be obtained by using traditional simulation methods, but these methods still have shortcomings. This work proposes an optimization method for traditional methods.

Methods

This study aims to introduce an effective solution for the rapid and accurate extraction of flood inundation areas, emphasizing the enhancement of extraction speed and dynamic monitoring throughout the flood event. The solution uses a normalized difference water index (NDWI), a refined threshold method, and a filtering process for microwave (radar) images. Sentinel-1 SAR (Synthetic Aperture Radar) and Sentinel-2 MSI (Multi-spectral Image) images served as the primary data sources. The Sentinel-2 images were preprocessed to extract pre-flood water bodies, while the Sentinel-1 SAR images were processed using the proposed filtering method to identify post-flood inundation areas.

Results

The application and validation of this framework are demonstrated through the case of the 2020 flood event in Tongling, Anhui Province. The framework’s performance was validated through comparison with ground truth data, yielding high kappa accuracies of 98% for optical images and 89% for Synthetic Aperture Radar. The findings highlight the framework’s ability to capture high-accuracy changes in flood inundation areas and to characterize the dynamic process of flood inundation area changes.

Discussion

This study contributes to the field by enhancing the extraction speed and scope of water bodies from SAR images and improving the quality of microwave remote sensing data processing. It offers valuable insights for emergency rapid response and situational awareness in the context of extreme weather events and associated flood disasters.

Published: December 2024

Objective

This study aims to evaluate the utility of polygenic risk scores (PRS) in women with early menopause (EM) and to investigate the clinical characteristics and risk factors associated with EM based on genetic risk.

Study design

Genotyping data and clinical data from women with EM and women with normal age of menopause retrieved from UK Biobank were used for early menopause risk prediction model establishment. Subsequently, 99 women diagnosed with EM and 1027 control women underwent PGT-M were recruited for model validation from across eight hospitals in China. According to PRS percentiles, these participants were further classified into high risk and intermediate risk groups. Characteristics among women at different risk levels were compared, and risk factors with early menopause were also statistical analyzed.

Main outcome measures

The proportion of women at high risk in EM and control groups; Characteristics with significant difference among women at different risk levels; risk factors associated with EM.

Results

The proportion of high-risk women in the EM group was significantly higher than that in control women underwent PGT-M (Group PGT-M) (OR = 3.78), and that in women with normal age menopause from UK Biobank (Group UKB) (OR = 5.11). Notably, the women with high risk of EM exhibited distinct characteristics compared to women with the intermediate-risk of EM, and identified several risk factors associated with EM.

Conclusions

We established a PRS model to serves as a valuable instrument for EM risk prediction. The exploratory analysis revealed that women with high risk of EM exhibited a higher height, suggesting EM related genetic loci may also influence growth and development level. Several risk factors were found to be potentially associated with EM, such as excessive familial contentment, COVID-19 vaccination, staying up late, and the husband’s engagement in smoking and alcohol abuse.
