Published: February 2024

Abstract. Mediterranean cyclones (MCs) govern extreme weather events across the Euro-African Basin, affecting the lives of hundreds of millions. Despite many studies addressing MCs in the last few decades, their correct simulation and prediction remain a significant challenge to the present day, which may be attributed to the large variability among MCs. Past classifications of MCs are primarily based on geographical and/or seasonal separations; however, here we focus on cyclone genesis and deepening mechanisms. A variety of processes combine to govern MC genesis and evolution, including adiabatic and diabatic processes, topographic influences, land–sea contrasts, and local temperature anomalies. As each process bears a distinct signature on the potential vorticity (PV) field, a PV approach is used to distinguish among different “types” of MCs. Here, a combined cyclone-tracking algorithm is used to detect 3190 Mediterranean cyclone tracks in ECMWF ERA5 from 1979–2020. Cyclone-centered, upper-level isentropic PV structures in the peak time of each cyclone track are classified using a self-organizing map (SOM). The SOM analysis reveals nine classes of Mediterranean cyclones, with distinct Rossby-wave-breaking patterns, discernible in corresponding PV structures. Although classified by upper-level PV structures, each class shows different contributions of lower-tropospheric PV and flow structures down to the surface. Unique cyclone life cycle characteristics, associated hazards (precipitation, winds, and temperature anomalies), and long-term trends, as well as synoptic, thermal, dynamical, seasonal, and geographical features of each cyclone class, indicate dominant processes in their evolution. Among others, the classification reveals the importance of topographically induced Rossby wave breaking to the generation of the most extreme Mediterranean cyclones. These results enhance our understanding of MC predictability by linking the large-scale Rossby wave formations and life cycles to coherent classes of under-predicted cyclone aspects.

Селективная лазерная обработка тонких поверхностных слоев металлических сплавов избирательно воздействует на отдельные дефектные области, такие как, концентраторы механических напряжений, зародыши разрушения, вершины трещин, частицы наноразмерного диапазона. Остальной материал практически не претерпевает изменений. Методом селективной лазерной обработки удается одновременно повысить микротвердость и вязкость микроразрушения, в частности, тонких лент твердых и хрупких аморфно-нанокристаллических металлических сплавов. Существенно, что при этом сохраняется исходная аморфно-нанокристаллическая структура материала. Воздействие на поверхность металлического сплава наносекундного лазерного импульса с высокой плотностью мощности сопровождается формированием плазмы лазерного пробоя, ударной волны и импульсного прогрева. Прогреву материала предшествует прохождение ударной волны сжатия, способной инициировать локальные деформации и разрушения. Неравномерность прогрева материала проявляется, в первую очередь, в дефектных областях и может приводить к релаксации механических напряжений за счет пластической деформации. Исследование взаимодействия теплового фронта, инициированного лазерным импульсом, с дефектами поверхностного слоя металлического сплава предполагает совершенствование физико-математических моделей данных процессов.
Selective laser treatment of thin surface layers of metallic alloys selectively affects certain defective areas, such as concentrators of mechanical stresses, fracture nuclei, crack tops, and particles of the nanoscale range. The rest of the material is practically unaffected. The method of selective laser treatment simultaneously increases microhardness and fracture toughness, in particular of thin ribbons of hard and brittle amorphous-nanocrystalline metal alloys. It is essential that the initial amorphous-nanocrystalline structure of the material is preserved. The impact on the surface of a metal alloy of a nanosecond laser pulse with high power density is accompanied by the formation of laser breakdown plasma, shock wave and pulse heating. Heating of the material is preceded by the passage of the compression shock wave, which can initiate local deformations and destructions. The uneven heating of the material is manifested primarily in the defective areas and can lead to relaxation of mechanical stresses due to plastic deformation. Study of interaction of the thermal front initiated by a laser pulse with defects in the surface layer of a metallic alloy involves the improvement of physical and mathematical models of these processes.

Update on the El Sauzal High-Sulfidation Gold-Silver Deposit at the
Initiation of Mining, Municipio de Urique, Chihuahua, Mexico
Authors: Weiss Steven I. , Espinoza Eduardo , Ronkos Charles 
Published: February 2024

Abstract
The E1 Sauzal gold-silver deposit is situated in the western Sierra Madre Occidental of Mexico, near the border between the states of Chihuahua and Sinaloa (Fig. 1). The deposit was discovered in 1995 by Francisco Gold during grass-roots exploration centered on the historic silver district of Batopilas, about 15 km to the NE (Fig. 1), (Charest et al., 2004). Colonial-era and other significant workings were completely absent at El Sauzal. Geologists travelling by mule and on foot in the deep, roadless canyon of the Rio Urique made the discovery by direct rock-chip sampling of resistant, highly altered outcrops. Between 1996 and 1999, a camp was established and a total of 188 diamond-drill holes were completed. Drilling was focused on the potential for shallow, oxidized ores and was largely guided by gold in rock-chip and channel samples.
Low-dose Potassium bromate enhances ischemia-reperfusion-induced gastric ulcer healing in Thyroidectomised Rats

Gastric ulcer healing is impaired in both hypothyroid and hyperthyroid conditions. Thyroid hormones regulate growth, energy metabolism and mitochondrial oxidative metabolism. Xenobiotics have been documented to negatively impact the thyroid gland at high doses but the redox and cellular interactions at low doses during wound healing process remains unclear. Potassium bromate has been documented to be toxic at high doses but there is dearth of information on its activities at a low dose in varied thyroid states which was evaluated in this study. 60 male Wistar rats (g, n=10) were randomised into 2 conditions: Normal, ulcerated untreated, ulcerated treated with 12.5mg/kg p.o KBrO3 and thyroidectomised groups: thyroidectomised ulcerated, thyroidectomised ulcer treated with KBrO3 and thyroidectomised treated with thyroxine (100µg/kg) Total thyroidectomy was used to model hypothyroidism, and ischaemia-reperfusion-induced gastric ulcers were monitored for healing. Daily body weights, Levels of thyroxine, Gastric mucin content, redox and sodium pump activity were examined alongside other markers of hepatic and haematological toxicity by days 3 and 7 post ulceration. Data were analysed using descriptive statistics and ANOVA α 0.05. The bromate-exposed hypothyroid rats showed increased gastric ulcer healing potential with reduced gastric epithelial oedema and inflammation; hepatic steatosis, and periportal inflammation. Haematological variables and markers of hepatic functions were normal. There were reduced levels of gastric and hepatic malondialdehyde levels. Thyroxine and potassium bromate treatment resolved the redox and cellular toxicity possibly via increasing catalase and sulfhydryl levels and increased Na+ K+ pump activity. We conclude that potassium bromate enhanced gastric ulcer healing in hypothyroid state, similar to thyroxine treatment.

Een nationale strafbaarstelling van ecocide: een vreemde eend in de strafrechtelijke bijt?
Begin juli 2023 heeft Kamerlid Van Raan het wetsvoorstel Wet strafbaarstelling ecocide ingediend, om zodoende ecocide onder een eigen titel in het commune Wetboek van Strafrecht strafbaar te stellen. In deze bijdrage wordt verkend in hoeverre de plaatsingskeuze van de initiatiefnemer voor een ecocidebepaling in het commune Wetboek van Strafrecht voor de hand ligt, en of gezien de specialistische aard van milieubepalingen voor de voorgenomen ecocidebepaling niet meer plaats is in het bijzonder strafrecht, in het bijzonder de WED. Dit wordt gedaan door de voorgestelde bepaling te analyseren aan de hand van uit de literatuur geïdentificeerde karakteristieken van het bijzonder strafrecht.

A Educação em Sexualidade é extremamente relevante na Educação Básica, tanto pelas realidades familiares e condições sociais diversas dos estudantes, quanto para a promoção de práticas de saúde pública. Assim, essa temática foi escolhida para compor o planejamento e execução de atividades propostas no componente curricular "Práticas Formativas e Educativas V", vinculada à matriz curricular do curso de Ciências Biológicas - Licenciatura, da Universidade Federal do Pampa - UNIPAMPA, Campus São Gabriel. Dessa forma, foi realizada uma pesquisa de nível exploratório e abordagem qualitativa em duas escolas públicas situadas no município de São Gabriel/RS, objetivando compreender qual a percepção e o entendimento dos estudantes sobre a temática da sexualidade, por meio de uma intervenção pedagógica para a promoção da sensibilização sobre a importância dos métodos contraceptivos na prevenção da gravidez não-planejada e na redução do risco de contaminação com Infecções Sexualmente Transmissíveis (ISTs). As atividades educativas da intervenção pedagógica seguiram a metodologia dos Três Momentos Pedagógicos, incluindo problematização inicial, organização e aplicação do conhecimento. Os resultados revelaram diferentes níveis de conhecimento entre os estudantes do Ensino Fundamental, enquanto os do Ensino Médio estavam mais familiarizados com a temática. Após a aplicação da intervenção, realizada com recursos lúdicos para promoção da aprendizagem e do pensamento crítico, pode-se inferir que houve melhoria na compreensão sobre contracepção e ISTs dos estudantes. As intervenções impactaram positivamente a formação dos futuros educadores, permitindo a aplicação prática de conhecimentos teóricos e preparando-os para desafios na escola.
Theta correspondences and arithmetic intersections
Authors:   , Gutiérrez Terradillos Armando 
Published: February 2024

(English) The thesis is mainly divided into two parts. In essence, the first one is an extension of the paper [Ter22]. Using the regularized Siege-Weil formula of [GQT14] we obtain an explicit expression for the truncated integral of the Siegel theta function. The main application of this result is an explicit formula for the integral of the logarithm of the Borcherds forms. The result involves different zeta values and coefficients of Eisenstein series. It completes the work of [Kud03]. Besides the aforementioned formula for the integral of the theta function, a detailed analysis of the Siegel theta function near the infinity is required. Chapter two is an extension of the work with Antonio Cauchi in [CT]. The purpose of this part is twofold. On the one hand, under some conditions, we show that the multiplicity of the Shalika model of unramified representations for the group GU(2, 2) is one. Using this result and following the ideas of [Sak06], we are able to find an expression of the Shalika functional in terms of the Satake parameter of a representation in GSp4. On the other hand, we use this result and to establish a relationship between a zeta integral for a group GU(2,2) and a twisted standard L-function of GSp4, where the relation between the involved automorphic representations is given by the theta correspondence.

The Mystery of Samba. HERMANO VIANNA: edited and translated by John Charles Chasteen. Chapel Hill and London: The University of North Carolina Press, 1999.
Authors: Austerlitz Paul 
Published: February 2024

This translation of Hermano Vianna's study of the Brazilian samba is an important contribution not only to English-language scholarship on Latin American music, but also to today's lively multidisciplinary discussion about race, nation, and popular culture. An anthropologist, Vianna discusses the social history of the samba (he also touches on some of samba's precursors and descendants), but the book is primarily a response to existing samba discourse among Brazilians. Because samba is considered the Brazilian "national rhythm," this discourse is inextricable from discussion about national identity. The book thus constitutes Vianna's take on nation, race, and music in Brazil. Accessible to readers unfamiliar with Brazilian studies, it is a good introduction to this field. John Charles Chasteen's English rendering reads exceptionally well; free of excessive jargon, its nuanced turns of phrase nicely frame the author's probing and provocative thoughts.
The Worm in the Wheat: Rosalie Evans and the Puebla-Tlaxcala Valley of Mexico, 1906-1927. TIMOTHY J. HENDERSON: Duke University Press, 1998.
Authors: Brewster Keith 
Published: February 2024

First published in 1926, Rosalie Evans’ Letters from Mexico presents the story of a North American woman’s unsuccessful struggle to hold back the tide of the Mexican Revolution. Ranging from the profoundly intimate to the consciously public, Rosalie Evans’ correspondence describes her efforts to protect her hacienda, San Pedro Coxtocán, from the designs of agraristas in the Puebla-Tlaxcala Valley. Thrust into the turmoil of a country at war with itself, she often appears to have been an innocent abroad. Although showing little awareness of political issues, her account reveals many of the strains within Mexican rural society at the beginning of the twentieth century. From her perspective, the hacienda offered security and sustenance to a Mexican peasantry that lacked the intelligence and ambition to better itself. She dismisses agraristas as unscrupulous radicals bent on self enrichment at the expense of landowners like herself.

Silvia Saytta nos acerca, en Regueros de tinta, al que sin duda fue el proyecto editorial argentino más exitoso de los años veinte: el diario Crítica. El impresionante volumen de la prensa de la época (en los años treinta Argentina llegó a ocupar el 4o puesto mundial en lectura per cápita de diarios) justifica por sí solo el interés del objeto de análisis. Si además consideramos su comprometida participación en la vida política y cultural, el estudio cobra mayor relevancia por constituir una sugerente forma de acercamiento al contexto ideológico de la época.

Jennifer Schirmer's book on the Guatemalan military, The Guatemalan Military Project: A Violence Called Democracy, is an important work for understanding the historical and political evolution of nations hitherto under the influence or control of the armed forces. She contends, and I fully agree, that since the military structured and arranged their own "exit" from politics, their view of society and politics still pervades state institutions and mechanisms. In general terms, the Guatemalan state still sees internal security as paramount in any attempt to build consensus.

Authors: Hernández Leonardo 
Published: February 2024

Peasants in Arms is the study of the rural, mountainous Nicaraguan municipality of Quilalí. Located in the north-central province or departamento of Nueva Segovia, Quilalí, along with many other towns near the Honduras-Nicaragua frontier, experienced intense armed conflict in the 1980s. From bases inside Honduras, armed guerrillas (known as contras) opposing the Sandinista regime would target and attack populations and productive centers inside Nicaragua, later retreating back into Honduras. Beginning in the early eighties, thousands of rural residents supported the contra cause by joining the rebels or providing them with supplies.
