One of the oldest and most well-known cosmetics, hair color has been used by numerous ancient cultures throughout history on both men and women. It involves treating hair with various chemical compounds for changing hair color. According to how long they remain in the hair, these products are primarily divided into two categories: temporary and permanent. This classification is consistent with the types of active substances used in the dyeing process as well as the dyeing method itself, which are referred to as non-oxidative and oxidative hair dye products, respectively. Permanent hair dyes often consist of active chemicals that are not dyed but are oxidized to provide the desired color. As a result, the phrase "oxidative hair dye" was emerged. The precursor part and coupler part are the two main ingredients in formulations for oxidative hair dyes. Quinonediimine intermediates are momentary compounds that are generated when combined with hydrogen peroxide (developer). As a result, the coupler agent and these compounds interact to form the appropriate hair dye molecule. Notably, the entire dyeing process requires both an alkaline medium and an oxidizing agent, often hydrogen peroxide, to ensure that the staining agents reach the cuticle widely. This review's objective is to provide information about hair dye formulations and mechanisms of action as well as repairing damaged hair and new applications.

The aim of this study is to investigate the endocrine factors thought to play a role in the regulation of energy homeostasis of irisin, adropin and preptin. Our study consists of men between 30-40 years of age including individuals from overweight or obese (n = 25), practicing regular aerobic exercise (n = 25) and sedentary (control, n = 25) groups. Irisin, adropin and preptin levels were studied on blood serum samples prepared using commercially available ELISA kit. The serum irisin level in the obese group was significantly higher than the both exercising and control groups (p
A method for using stationary networks to observe long-term trends of on-road emission factors of primary aerosol from heavy-duty vehicles
Authors: Fitzmaurice Helen L. , Cohen Ronald C.
Published: December 2022

Abstract. Heavy-duty vehicles (HDVs) contribute a significant, but
decreasing, fraction of primary aerosol emissions in urban areas. Previous studies have shown spatial heterogeneity in compliance with regulations. Consequently, location-specific emission factors are necessary to describe
primary particulate matter (PM) emissions by HDVs. Using near-road observations from the Bay Area Air Quality Management District (BAAQMD)
network over the 2009–2020 period in combination with Caltrans measurements of vehicle number and type, we determine primary PM2.5 emission factors from HDVs on highways in the San Francisco Bay area. We demonstrate that HDV primary aerosol emission factors derived using this method are in line with observations by other studies, that they decreased a by a factor of ∼ 9 in the past decade, and that emissions at some sites remain higher than would be expected if all HDVs were in compliance with California HDV regulations.
Changes in the annual sea ice freeze–thaw cycle in the Arctic Ocean from 2001 to 2018
Authors: Lin Long , Lei Ruibo , Hoppmann Mario , Perovich Donald K. , He Hailun
Published: December 2022

Abstract. The annual sea ice freeze–thaw cycle plays a crucial role in the
Arctic atmosphere—ice–ocean system, regulating the seasonal energy balance
of sea ice and the underlying upper-ocean. Previous studies of the sea ice
freeze–thaw cycle were often based on limited accessible in situ or easily
available remotely sensed observations of the surface. To better understand
the responses of the sea ice to climate change and its coupling to the upper
ocean, we combine measurements of the ice surface and bottom using
multisource data to investigate the temporal and spatial variations in the
freeze–thaw cycle of Arctic sea ice. Observations by 69 sea ice mass balance
buoys (IMBs) collected from 2001 to 2018 revealed that the average ice basal
melt onset in the Beaufort Gyre occurred on 23 May (±6 d),
approximately 17 d earlier than the surface melt onset. The average ice
basal melt onset in the central Arctic Ocean occurred on 17 June (±9 d), which was comparable with the surface melt onset. This difference was
mainly attributed to the distinct seasonal variations of oceanic heat
available to sea ice melt between the two regions. The overall average onset
of basal ice growth of the pan Arctic Ocean occurred on 14 November (±21 d), lagging approximately 3 months behind the surface freeze
onset. This temporal delay was caused by a combination of cooling the sea
ice, the ocean mixed layer, and the ocean subsurface layer, as well as the
thermal buffering of snow atop the ice. In the Beaufort Gyre region, both
(Lagrangian) IMB observations (2001–2018) and (Eulerian) moored upward-looking sonar (ULS) observations (2003–2018) revealed a trend towards
earlier basal melt onset, mainly linked to the earlier warming of the
surface ocean. A trend towards earlier onset of basal ice growth was also
identified from the IMB observations (multiyear ice), which we attributed to
the overall reduction of ice thickness. In contrast, a trend towards delayed
onset of basal ice growth was identified from the ULS observations, which
was explained by the fact that the ice cover melted almost entirely by the
end of summer in recent years.

Authors: KADI Furkan , COŞKUN Gökhan , BÜYÜKKAYA Ekrem
Published: December 2022

Bu çalışmada hastane binalarında yangın anında kullanıcıların tahliyesi ve dumandan etkilenme oranlarının simülasyon destekli olarak incelenmesi için HAD tabanlı yangın simülasyonu Fire Dynamic Simulator (FDS) ile birlikte tahliye simülasyonu kullanılarak, yatay tahliye, asistanlı tahliye gibi hastane binalarına özel tahliye olanaklarının irdelenmesi hedeflenmiştir. Yangın simülasyonunda ilgili yönetmelik ve standartlarda belirtilen yangın yükleri baz alınarak hesaplamalar yapılmıştır. Hastane binalarında bulunacak yaşam destek ünitesine bağlı, medikal gazlara muhtaç, hareket kabiliyetleri sınırlı vb. hastaların yangın anında tahliyesi ve dumandan etkilenme oranları incelenmiştir. Örnek bir hastane mimarisi üzerinden tahliye olanaklarının yeterliliği araştırılmıştır. Yapılacak tahliye simülasyonunda hastane ortamında bulunabilecek çeşitli hareket kabiliyetlerine sahip bina kullanıcılarının durumları göz önünde bulundurulmuştur. Bu bağlamda tahliye simülasyonu programında kullanıcı grupları oluşturularak gerçek duruma en yakın veriler elde edilmesi hedeflenmiştir. Yangın simülasyonu yazılımında hazırlanacak örnek yangın durumu tahliye simülasyonu yazılımına aktarılacak ve bu programda mimari üzerinde yerleştirilmiş olan bina kullanıcılarının tahliye süreleri, dumana maruz kalma düzeyleri, maruz kalınan sıcaklık değerleri ve yangın emisyonu olan toksik gazlara maruziyet dereceleri irdelenmiştir.

Alışveriş merkezleri kullanıcı bakımından antropometrik değerleri çok farklı olan hemen hemen toplumda bulunan her tip ve yaşta insanın bulunabileceği mekânlardır. Bu mekânlarda gerçek anlamda bir tahliye tatbikatı yapılması ve deneysel sonuçlar edinilebilmesi geleneksel yöntemler kullanılarak oldukça güçtür ve günümüze kadar bu tip çalışmalar nadir olarak yapılabilmiştir. Yaşanan yangınların incelenmesi ile de bu tip binaların yangında can güvenliği performansının detaylı irdelenebilmesi, mimari olarak yaratıcı fikirler ile inşa edilen bu tip bir birinden oldukça farklı yapılar için uygulanabilir değildir. Günümüzde bu tip binalardaki yangınların sonuçlarının öngörülüp, irdelenebilmesi için bilgisayar destekli programlardan yararlanılabilmektedir. Bu çalışmanın konusu; örnek bir Alışveriş merkezi yangında can güvenliği performansının, bilgisayar destekli programlar yardımı ile farklı yangın senaryoları için tespit edilmesi ve çıkan sonuçların irdelenmesidir. Alışveriş merkezlerinde çıkan yangınlarda misafirlerin daha çok binaya girdikleri güzergâhtan panik halinde çıkmaya çalıştıkları tecrübe edilmiş bir durumdur. Zira kullanıcıların bina tahliye olanakları ile ilgili önceden bilgi alma ihtimalleri olmadığı gibi çok farklı eğitim seviyelerinde ve değişken sosyal statülerde olmaları nedeni ile yangında davranış hakkındaki ortak eğitim seviyesi olabilecek en düşük seviyededir.

Yasal mevzuatlar ülkemizde yangın tahliye olanaklarının sadece yönergesel yöntemler ile boyutlandırmasına müsaade etmektedir. Bu yöntem ile tasarlanmış bir binada bina tahliye performansının ölçülmesi bir zaruret değildir. BYKHY gereği tüm binalarda senede en az bir sefer tahliye tatbikatı yapılmalıdır, AVM binalarında ise yönetmelikte yer almasına karşın uygulanabilir olmadığı için tam tahliye tatbikatı hiçbir zaman yapılmamaktadır. Bu nedenlerden ötürü AVM binaları sıradan ofis, fabrika gibi binalara nazaran yangında tahliye performansı öngörülebilir veya kontrol edilebilir yapılar değildir. Yönergesel olarak tasarlanan bir can güvenliği sisteminin performans bazlı bir ölçüm metodu kullanılarak değişik senaryolar için sınanması, ve senaryolar arasındaki performans farklarının incelenebilmesi bu çalışmanın öne süreceği görüşlere dayanak oluşturacaktır.

Published: December 2022

This study represents characterization of different metals present in Andrographis paniculata (a medicinal herb). The plant samples were collected from urban and rural areas of Khordha district, Odisha, India. The solid powdered samples from different parts of the plants were analyzed using various chemical and physical characterization techniques and all the data provides a clear description about the metal and mineral contents in the plant parts qualitatively and quantitatively as well. X-ray Fluorescence study was done to know the presence of different metals (including other elements) qualitatively. The collected samples were taken for ashing, followed by acid digestion and analyzed by AAS and ICP-OES (Pb, Cr, Mn, Co, Zn, Cu, Cr, V, Na, Ca, and Mg), FES (Ca, Na, and K) respectively. It has been found that leaves of the plants of both the regions are rich in Fe, Mg, Ca, K, Mn etc. In addition to these metals Pb, Cr, Co, Pd, and V also exists, but in low concentrations which have negligible impact on the medicinal characteristics of the plant (but are toxic). Structural characterization (FESEM) is under process.
Analysis and Application of Advanced Algorithm for Aeronautical Flows
Authors: Sherwin Spencer
Published: December 2022

Advanced high order methods using Spectral/hp element discretization including Galerkin, Discontinuous Galerkin (DG) and Flux Reconstruction (FR) formulations are gaining notable interest in both the academic and industrial sectors. The compact nature of the approach is not only attractive from the perspective of implementation on modern computational hardware but also provides a consistent geometric and spatially localized accuracy unlike many high order finite volume methods. These features make the methodology attractive in complex geometry flows involving transitional and turbulent boundary layers demanding a high level of accuracy for high end engineering applications that commonly arise in the aeronautical sector. In this presentation, we will present our current work on developing a spectral/hp element implicit compressible flow solver for aeronautically related application. The demands of handling “industrial strength” complex geometries at high Reynolds numbers necessarily leads to severe time step restrictions when using explicit time stepping approaches. We have therefore developed a Jacobian-Free-Newton-Krylov (JFNK) implicit solver which makes use of the explicit technique but still require the suitable preconditioners that can be demanding from a memory footprint perspective. After motivating the need for this type of solver we will outline the implementation challenges behind the scheme and demonstrate the suitability of the approach for a number of representative examples.
Effective boundary conditions at a regularly microstructured wall
Authors: Bottaro Alessandro
Published: December 2022

The talk will discuss effective boundary conditions, correct to second order in a small parameter epsilon, for a rough wall with periodic micro-indentations. The length scale of the indentations is l, and epsilon = l/L << 1, with L a characteristic length of the macroscopic problem. At leading order the Navier slip condition is recovered; at next order the slip velocity includes a term arising from the streamwise pressure gradient. At second order also a transpiration velocity appears at the fictitious wall where the effective boundary conditions are enforced. For ease of derivation, the microscopic theory, based on a power series expansion of the dependent variables, will be limited to the case of two- dimensional roughness, the three-dimensional extension being trivial. The application to a macroscopic problem is carried out considering the case of the Hiemenz stagnation point flow over a rough wall.
Bio-inspired aerofoil adaptations for the reduction of turbulence interaction noise
Authors: Ayton Lorna
Published: December 2022

A dominant source of broadband aeroengine noise arises when the unsteady wakes shed from rotors interact with downstream stators. This so-called leading-edge noise cannot be eliminated, but it can be reduced. By altering the spanwise geometry of the leading edge of an aerofoil it is known through experimental testing that leading-edge noise can be significantly reduced over broadband frequencies. In recent years, a multitude of different shapes have been tested and all are seen to have benefits for different frequency ranges, which may be ideal for the reduction of tonal noise, but the question remains; which design is optimal for broadband noise reduction? This talk presents a theoretical model for leading-edge noise, both for straight edges and serrated edges. Through theoretical optimisation, a set of rules are proposed which lead to an optimal design for broadband leading-edge noise reduction. Experimental data on sample new designs validates the theoretical predictions and illustrates up to an additional 7dB noise reduction verses conventional serrated designs.
Linear and ponderal growth changes in boys and girls from Puerto Madryn (Patagonia, Argentina) between 2001 and 2016
Authors: Navazo Bárbara , Dahinten Silvia Lucrecia
Published: December 2022

Background: The phenotypic plasticity in growth pattern that takes place over time is described as “secular trend”. The presence of secular changes evidences shifts in the environmental conditions under which a population lives. In this regard, the study of the population residing in the northeast of Argentine Patagonia is interesting because it underwent a rapid demographic growth and urban sprawl in the last 50 years.

Objective: To compare height and body weight of two groups of boys and girls between 6 and 14 years old from Puerto Madryn (northeast of Argentine Patagonia) and estimate secular trend changes during the first decades of 21st century.

Sample and Methods: Height and body weight of two groups of schoolchildren were compared. Data of the first group (G1) was collected in the 2001–2006 period, and of the second (G2) during 2014–2016.

To analyze the comparison between groups, the Friedman and Wilcoxon test (p < 0.05) were used. Centile values (3rd, 50th and 97th) of the variables by sex and age in both groups were also calculated. Then, they were compared using the Wilcoxon test.

Results: Both sexes showed statistically significant differences for height in all centiles and for body weight in the 50th and 97th centiles. G2 values were above G1 for most ages.

Conclusion: Boys and girls from Puerto Madryn show a positive secular trend in linear and ponderal growth patterns. These changes, registered during the first decades of the 21st century, are possibly related to the urban sprawl of the city and the variations in the associated socio-environmental and demographic conditions.
“Entediado com o minimalismo”

Published: December 2022

O estilo “pós-minimalista” de John Adams foi explorado pela primeira vez em seu primeiro opus, China Gates para piano solo. Faz-se aqui uma análise da peça revelando elementos deste estilo, incluindo a simplicidade, repetição e simetria misturadas com variação, tensão e resolução, e uma medida de imprevisibilidade. A descrição de Adams da peça é a de um “palíndromo quase perfeito”, e este artigo mostra como os palíndromos se manifestam tanto em grande quanto em pequena escala, além de mostrar sua imperfeição pós-minimalista e proposital.
Algunas consideraciones formales y armónicas en la zamba argentina
Authors: Martínez Alejandro , Rodríguez Edgardo
Published: December 2022

La zamba es una danza y un género musical muy popular del folklore argentino. Considerada desde el punto de vista musical, la zamba posee una forma específica. Este trabajo intenta concebir la forma en este género desde un enfoque formal funcional, en la tradición de Schoenberg-Ratz-Caplin. Otra influencia es la concepción dialógica de la forma, tal como la plantean Hepokoski y Darcy, que nos permite establecer los aspectos normativos y convencionales del género. Presentamos los fundamentos de este enfoque, junto a varios ejemplos musicales y nos concentramos en algunos aspectos armónicos específicos del primer módulo de la estrofa, en especial el patrón armónico denominado alejamiento-retorno.

Gender Equity in M-19 Combat, Colombia, South America, 1970-1989
Authors: Wakeland R. G.
Published: December 2022

Between 1970 and 1989 the M-19 guerrilla group in Colombia, South America sought regime change via armed conflict. Interviews and autobiographies as well as government and military observations of engagements involving weapons provided sources for a gender role analysis. The author argued that male and female M-19 individuals adopting arms participated in gender equity. Although there were statistically greater numbers of male than female combatants and authoritarian figures in combat, decisions to perpetrate armed violence were autonomous and suicidal. Women as well as men were given equal opportunity to kill and be killed. M-19 elevated anyone who carried a weapon to equal status of liberator in the model of Simon Bolívar, towards its goal of a second national liberation. A literature review presented other theories and conclusions of gender roles among M-19.

The study aimed to develop and evaluate the instructional module for special program in journalism for grade 8 students. It is geared towards probing the errors encountered in learning resource construction and the recommendations in enhancing the instructional material through questionnaires and guidelines for learning resource material (LRM) production. Data were gathered from forty Grade 8 Journalism students enrolled at an Integrated High School in Laguna, Philippines and ten specialists who were purposively selected. The data were collected and treated using Mean. Findings revealed that the student-evaluators strongly agree on the rating criteria of the instructional module in terms of format, content, clarity and usefulness. On the other hand, the specialists rated the instructional module passed on content, format and presentation and organization criteria but failed on accuracy and up-to-datedness of information.
Effect of Teachers’ Attitudes on Behavioral Intentions toward the New Curriculum Implementation: Mediating Role of Perceived Behavioral Control
Authors: Khine Thae Hsu
Published: December 2022

In the education context, a small number of studies dealt with the effect of teachers’ attitudes on behavioral intentions toward the curriculum change in its implementation stage by the mediating role of their perceived behavioral control. Hence, this study specifically focuses on understanding the effects of mediating variables on the relationship between primary teachers’ attitudes and behavioral intentions toward implementing the new curriculum. The study investigated 627 primary teachers in Myanmar’s government schools in the region of Naypyitaw Union Territory located in the central part of Myanmar, during the academic year 2021-2022 using teachers’ attitudes questionnaire, behavioral intentions questionnaire, and perceived behavioral control questionnaire. Results revealed that teachers had positive attitudes and supportive behavioral intentions toward implementing the new curriculum. The findings also showed teachers’ attitudes had a significant positive predictive effect on their behavioral intentions (r = 0.5, p < 0.01). Moreover, perceived behavioral control had a partially mediating effect between teachers’ attitudes and behavioral intentions toward implementing the new curriculum. In the implementation stage of the new curriculum, the finding revealed the importance of teachers’ perceptions of behavioral control in enhancing their actual new curriculum implementation behavior. It also provided additional empirical evidence in the educational context and also for the policy-makers in education.

Published: December 2022

Aims: Bile duct injury (BDI) in laparoscopic cholecystectomy (LC) has a significant impact on morbidity and mortality. Although the critical view of safety (CVS) concept is the most widely supported approach to prevent BDI, alternative approaches are used as well. The aim was to evaluate the incidence, severity, and management of bile duct injury in LC, using a posterior infundibular approach.

Methods: This retrospective, monocentric cohort study includes patients who underwent LC for gallstone disease. Data were collected in a prospectively maintained database. Patients with BDI were identified and were analyzed in-depth.

Results: Between 1999 and 2018, 8389 consecutive patients were included (M/F 3288/5101; mean age 55 (standard deviation; SD ± 17) years). Mean length of postoperative hospital stay was two days (SD ± 4). Fourteen patients died after LC and 21 patients were identified with BDI. Seventeen BDI (81%) patients were managed minimally invasive (14 endoscopic, 3 laparoscopic), and 4 patients via laparotomy (3 hepaticojejunostomy, 1 primary suture). Severe complications (Clavien-Dindo ≥3) after BDI repair were observed in 6 patients. There was no BDI-related mortality. Median follow-up time was 113 months (range 5–238).

Conclusion: A posterior infundibular approach in LC was associated with a low incidence of BDI and no BDI-related mortality.

Envejecimiento y edadismo: un problema de salud pública
Authors: López Lizmery , Chipia Joan
Published: December 2022

La vejez se considera el resultado inevitable del proceso vital, donde se producen efectos físicos, mentales y sociales; se presentan actitudes hacia las personas mayores, en la edad avanzada y el proceso de envejecimiento existen creencias que consideran un adulto mayor como una carga para la sociedad; identificándose como prácticas discriminatorias hacia este grupo poblacional. La investigación tuvo como objetivo describir el envejecimiento y el edadismo como problema de salud pública. Metodología: enfoque cualitativo, tipo exploratorio y diseño no experimental. La técnica utilizada fue la entrevista y como instrumento se realizó una guía de entrevista, los sujetos entrevistados fueron tres especialistas vinculados con la salud pública, con más de 30 años de experiencia clínica y académica. Resultados: se obtuvo una falta de políticas públicas definidas para la prevención de enfermedades degenerativas de la tercera edad, además en la sociedad se muestran actitudes y conductas discriminatorias hacia el adulto mayor por la falta de educación y enseñanza de valores desde la infancia, por ello, deben existir estrategias destinadas a reorientar los servicios de salud para la atención del anciano con técnicas accesibles y personal capacitado. Se concluye que tanto el envejecimiento como el edadismo constituyen un problema de salud pública, pues no existen políticas públicas definidas, teniendo en cuenta que la población adulta mayor va en crecimiento y no se presta la atención debida para el desarrollo de planes de las enfermedades de esta etapa.

Published: December 2022

El impacto de los cambios bioquímicos en el adulto mayor tiene el mismo factor en común ya que, presentan alteraciones en su vejez y los descritos se ven en el metabolismo de la glucosa como: morfológicos y funcionales. Los primeros se asocian a un aumento de grasa visceral, infiltración grasa de tejidos y menor masa de células beta, los segundos se observan en una mayor producción de adipocinas factores inflamatorios, al igual que, una mayor resistencia insulínica y diabetes. Los cambios en el metabolismo lipídico fluctúan y alteran las lipoproteínas, colesterol y triglicéridos; se puede evidenciar al medir dichos analitos séricos provocando así dislipidemias. La investigación está enfocada en identificar los principales cambios bioquímicos en los análisis de glucosa y perfil lipídico (colesterol, triglicéridos, HDL y LDL) en una población de 89 adultos mayores de la provincia de Tungurahua, Ecuador, a través de un estudio con diseño descriptivo, transversal, de campo. Mediante el software Minitab versión 18.1, se pudo determinar que con un intervalo de confianza del 95% no existen cambios en los analitos de glucosa, colesterol total, HDL y LDL. Por otra parte, con un intervalo de confianza del 95% del 100%, el 14% pueden tener un valor sobre los 150mg/dL en el analito de triglicéridos tanto en hombres como en mujeres. El porcentaje de pacientes con tendencia a padecer cambios bioquímicos es relativamente bajo en nuestra investigación, por lo que se ha determinado como un factor protector la actividad física que desarrollan los pacientes del estudio dado su forma de trabajo, pese a ello se destaca a la hipertrigliceridemia en un 14%. Asimismo, un alto porcentaje de pacientes geriátricos manifiesta haber desarrollado diabetes en un 64% (n= 57), pero demuestran un escaso conocimiento de la enfermedad, ya que dicen padecerla, pero no se refleja en los resultados de laboratorio que presenten tal enfermedad.

El uso de plaguicidas en regiones agrícolas constituye un problema de salud pública, debido a la exposición ocupacional directa de los agricultores y a la exposición no ocupacional, o indirecta de la población general. El objetivo fue describir los síntomas y signos por exposición directa e indirecta a plaguicidas en habitantes de Bailadores municipio Rivas Dávila estado Mérida, 2018. Metodología: investigación de tipo descriptiva y diseño transversal. La muestra estuvo constituida por individuos de género masculino, 15 agricultores o Grupo Exposición Directa (GED) y 15 no dedicados a actividades agrícolas de la misma localidad, o Grupo Exposición Indirecta (GEI). Se utilizó un instrumento en el que se registraron los datos demográficos, síntomas dermatológicos, neurológicos, oculares, cardiorrespiratorios y digestivos; así como los resultados del examen físico de estos sistemas orgánicos. Resultados: la edad promedio fue 41,73 ± 15,85 años en el GED y 47,67 ± 12,77 años para el GEI. De los 22 síntomas referidos y 14 signos hallados en el examen físico de participantes de ambos grupos, solo hubo predominio significativo en el GED para el cansancio (p=0,035), la dermatitis (p=0,008) y el lagrimeo (p= 0,006). El hallazgo de síntomas y signos en ambos grupos de estudio sugiere que la exposición a plaguicidas, tanto directa como indirecta, tiene un impacto negativo en diferentes sistemas orgánicos de los habitantes del municipio de estudio; sin embargo, se requieren investigaciones con mayor número de participantes y la inclusión del género femenino y población pediátrica del municipio, para confirmar y ampliar estos resultados.

El síndrome de Asherman representa un problema de salud, debido a que ocasiona alteraciones ginecológicas que afectan el ciclo menstrual y la función reproductiva. Actualmente, la histeroscopia utilizada para eliminar las adherencias no logra recuperar la anatomía endometrial por lo que el porcentaje de recurrencias es elevado y la tasa de embarazos es baja, por lo tanto, se necesita de métodos coadyuvantes para evitar o disminuir estas recidivas y mejorar la receptividad. El objetivo de esta revisión bibliográfica fue describir las principales alternativas terapéuticas coadyuvantes empleadas en el manejo postoperatorio de las recidivas del Síndrome de Asherman. Para ello, se realizó una búsqueda en las bases de datos Google Académico, PubMed y Springer, se encontró un total de 898 artículos, se excluyeron aquellos que tenían otras variables de estudio como: aborto, infertilidad, embarazo, los que no disponían de texto completo y aquellos cuya fecha de publicación fue antes del 2017, al final se seleccionaron 32 artículos. Resultados: los estrógenos en combinación con progesterona a dosis bajas ayudan a mejorar la función endometrial, por otro lado, el DIU con ácido hialurónico representa la mejor opción para una buena reparación endometrial. Conclusión: el uso de barreras sólidas combinadas con geles y la terapia hormonal constituye la alternativa de mayor eficacia en el tratamiento de las recidivas del síndrome de Asherman, y los avances en la terapia con células madre garantizan una recuperación total, pero aún existen limitaciones que impiden su uso.

Berkurangnya lahan terbuka dan tidak lancarnya saluran air mengakibatkan genangan air dan banjir menjadi alasan beberapa ruas jalan dan wilayah di Kota Palembang. Pergerakkan air yang tidak lancar ini mengakibatkan luapan air yang berlebihan. Salah satu bentuk kepedulian dan aksi nyata atas permasalahan lingkungan tersebut, tim pelaksana pengabdian kepada masyarakat menginsiasi pendampingan pembuatan lubang resapan biopori lahan terbuka yang sempit. Salah satu wilayah di perkotaan yang tedampak banjir adalah KelurahanSialang Kecamatan Sako. Dua rukun tetangga yang akan menjadi lokasi kegiatan ini, yaitu RT 01 dan RT 61. Inisiasi pembuatan lubang biopori ini merupakan kesepakatan dengan warga untuk mengurangi genangan atau banjir di pemukiman.  Kegiatan pelaksanaan pendampingan dilakukan dengan metode partisipasi antara masyarakat, tim pelaksana dari perguruan tinggi dan pihak kelurahan serta kecamatan. Kegiatan berlangsung melalui lima tahapan aksi, yaitu pra persiapan, persiapan, pelaksanaan serta monitoring dan evaluasi. Sosialisasi juga dilakukan untuk mengenalkan apa yang dimaksud pembuatan biopori, fungsi dan manfaat jangka pendek dan panjang. Untuk membuat lunbang biopori dibutuhkan pipa PVC. Hasil kegiatan ini adanya kerjasama partisipatif dari masyarakat melalui kesadaran dan memahami bahwa pembuatan biopori adalah salah satu cara yang efektif dalam pencegahan banjir. Rekomendasi kagiatan ini adalah pentingnya meningkatkan kolaborasi antara perguruan tinggi, masyarakat dan pemerintah daerah untuk mengimplementasikan kebijakan pro perubahan iklim yang dimulai dari lingkungan rumah sendiri.
Building Bridges: Innovations and Approaches to Increase Financing to Indigenous and Afro-descendant Peoples and Local Communities for Climate and Conservation Goals
Authors:   Rights and Resources Initiative
Published: December 2022

Indigenous Peoples, local communities, and Afro-descendant Peoples must be recognized and supported as key actors and leaders in combatting climate change and conserving the Earth’s natural diversity to have any hope of reaching global climate and biodiversity goals. The men and women in these groups have long stewarded their lands, territories, and resources, across an estimated 50% of the global land area. Scientific studies and local experience have increasingly demonstrated that Indigenous Peoples, Afro-descendant Peoples, and local communities with secure tenure and support are often highly effective stewards of forests and other natural ecosystems, with high levels of ecological intactness and low levels of deforestation in their lands relative to other areas. This paper provides an initial overview of emerging experience with “fit for purpose” approaches to channel resources at scale to collective rightsholders and their supporting organizations to conserve and manage forests and rural landscapes. It draws on presentations and discussions from Path to Scale dialogues, a review of recent, relevant literature, public events and further inputs from Path to Scale participants and RRI coalition members.

Published: December 2022

Objetivo. Analizar la importancia de la reconversión de los sistemas convencionales a sistemas agroecológicos de producción porcícola a través de sistemas de alimentación no convencionales en el trópico. Materiales y métodos. Se revisaron 122 artículos y se seleccionaron 100, la base de la reseña se orientó a la utilización de alimentos alternativos, con el mayor peso de las citas, sin desestimar el resto de los temas. Resultados. Se dispone de tecnologías y resultados en productos y subproductos que se generan de la caña de azúcar, variedades de altos rendimientos de yuca y boniato, el cultivo de plantas arbóreas proteínicas con alto valor nutricional y el efecto de aditivos con significativos resultados, por mejorar la digestibilidad y la salud sin altos costos. Cerdos en pastoreo implica una contribución significativa en diferentes sistemas, sean de subsistencia o manejo intensivo. La integración de la producción porcina a la agricultura puede convertirse en una de las cadenas que mejor aprovechen la biomasa y energía fotoquímica en estos cultivos; otros factores, como la genética, las instalaciones y el reciclaje a partir del uso de la cama profunda y biodigestores son necesidad frente al cambio climático. El cerdo, además de ser un animal prolífico y adaptable a diferentes condiciones, puede alimentarse de forma no convencional y utilizarse como el principal suministro de proteína animal para consumo humano, sus excreciones pueden reciclarse a través de diferentes tecnologías y disminuir la carga contaminante. Conclusión. El cerdo en el trópico tiene gran importancia para los países en desarrollo por las condiciones sociales, económicas y tecnológicas que contribuyen a la economía circular y a la soberanía alimentaria.

Published: December 2022

Objetivo. Analizar sistemáticamente los instrumentos de planeación y legislación ambiental de las entidades federativas de México para identificar los diferentes programas, proyectos y acciones forestales, y que se pueden replicar en función del potencial forestal y características propias de cada entidad federativa, a través de las instituciones y estructuras de gobierno existentes encargadas de coordinar las políticas forestales. Materiales y métodos. Se identificaron las leyes forestales, planes de desarrollo y programas sectoriales; se conocieron los programas, acciones y estímulos institucionales en materia forestal que promueven las entidades federativas del país. Resultados. Con base al análisis realizado, se identificó que cinco entidades poseen organismos públicos descentralizados encargados de coordinar las políticas públicas forestales: Estado de México, Michoacán, Nayarit, Oaxaca y Tabasco. Adicionalmente y a partir de esta información, se identificaron las oportunidades que pueden representar un detonante para las entidades, a través de las cuales se pueden definir estrategias y acciones que permitan instrumentar políticas públicas que fortalezcan el desarrollo forestal y que, a su vez, den paso a la captación de recursos que contribuyan al fortalecimiento del cuidado, protección, restauración y manejo de los bosques del país y bienestar de los dueños y poseedores de los recursos forestales. Conclusión. Las 32 entidades federativas del país cuentan con instrumentos normativos y potencial forestal que justifica la implementación de programas, a través de los cuales se otorguen estímulos económicos a los núcleos agrarios y productores forestales y, con ello, coadyuvar al desarrollo del sector forestal.
