Mục tiêu nghiên cứu: Mô tả đặc điểm lâm sàng, đối chiếu hình ảnh nội soi thường, nội soi tiếp xúc tăng cường và kết quả mô bệnh học khối u thanh quản giai đoạn tiền ung thư và ung thư tại Bệnh viện Tai Mũi Họng Trung Ương từ 2023 – 2024. Đối tượng và phương pháp nghiên cứu: Nghiên cứu mô tả trên 61 người bệnh được chẩn đoán xác định có khối u thanh quản tại Trung tâm U bướu Bệnh viện Tai Mũi Họng Trung Ương từ tháng 8/2023 đến tháng 9/2024. Trong số này, 3 bệnh nhân không thực hiện được nội soi tiếp xúc tăng cường do giả mạc, tư thế khó, hoặc chảy máu. Do đó, 58 bệnh nhân được đưa vào phân tích. Kết quả: Toàn bộ đối tượng nghiên cứu là nam giới. Độ tuổi trung bình là 61,6 ± 8,1 tuổi. Lý do chủ yếu khiến người bệnh đi khám chữa bệnh là khàn tiếng. Đa số bệnh nhân đến khám trong khoảng thời gian từ 3 – 6 tháng kể từ khi triệu chứng xuất hiện (39,7%), sau đó là khoảng thời gian từ 1 đến 3 tháng (27,6%). Thể sùi chiếm tỷ lệ cao nhất với 91,4%. Bệnh nhân có khối u nằm tại vị trí thanh môn chiếm tỷ lệ cao nhất (65,5%). Tỷ lệ bệnh nhân có tình trạng dây thanh di động bình thường và hạn chế lần lượt là 65,5% và 27,6%. Theo hình ảnh nội soi thường các khối u chỉ được đánh giá trên tiêu chí niêm mạc sùi loét, vùng lan trên các tầng thanh quản theo một cách chủ quan mà không được lượng giá, một số trường hợp không thể đánh giá được hết vùng tổn thương cũng như tiên lượng được tính chất lành tính hay ác tính của tổn thương, còn với nội soi tiếp xúc tăng cường có 17 trường hợp bạch sản được đánh giá thuộc cấu trúc tuýp 2 và 3, có tới 41/58 trường hợp hình ảnh soi được phân tuýp 4 được chẩn đoán mô bệnh học là ung thư biểu mô vảy. Ngoài ra với một số trường hợp phân tuýp 1 của tổn thương dạng polyp, tổn thương viêm trong nhóm chứng cũng được đánh giá rõ ràng và khách quan theo đúng phân loại của Puxeddu và cộng sự đã phát hiện cấu trúc mạch tân sinh của khối u thanh quản – hạ họng trong nội soi tiếp xúc tăng cường. Độ chính xác về chẩn đoán phân biệt giữa mô bình thường và bạch sản với ung thư biểu mô là 100%. Kết luận: Nội soi tiếp xúc tăng cường giúp dự đoán những thay đổi mô học trong tổn thương tiền ung thư và ung thư thanh quản dựa trên hình ảnh và cấu trúc mạch máu. Phương pháp này là một phương pháp quan trọng giúp quá trình chẩn đoán, điều trị, và theo dõi bệnh nhân tiền ung thư và ung thư thanh quản

Acute Diarrhea in Children
Authors: Husniana Ilmida
Published: September 2024

Background: Acute diarrhea is the most frequent gastrointestinal disorder and the main cause of dehydration in childhood. Diarrhoea is the fifth leading cause of death in children under the age of five years and rotavirus is the leading aetiology in this age group. Six risk factors (childhood wasting, unsafe water, oral rehydration, unsafe sanitation, handwashing, and therapeutic zinc) can cause diarrhea death in sub-Saharan Africa. Case: a 7-month-old baby came to the hospital complaining of fever and diarrhea one day before. The patient was hospitalized because the baby’s condition required observation. 16 days after hospitalization, the patient came back with complaints of diarrhea that had persisted for more than 2 weeks. Conclusion: Diarrhea in children requires special attention because even though it sounds trivial, if it is not handled properly it can cause serious problems, even death.
Single and mixed dithiocarbamato metal(III) complexes (Co, Rh, and Ir): Crystal and molecular structure description and interplay
Authors: Shotonwa Ibukun Oluwaseun , Oduwole Adebayo Ponle , Agosu Oluwapelumi Martin , Yusuf Abosede Funke , Eze Simeon Okechukwu
Published: September 2024

This review focuses on the crystal and molecular structures of single and mixed dithiocarbamate ligands of cobalt, rhodium, and iridium in the +3 oxidation state. The complexities of their chelating and bridging modes come into play through modification of the substituents on the carbamate nitrogen atoms of the ligands and additional coordination of secondary phosphino-containing ligands, culminating in various applications such as biological, analytical, medicine, and catalysis. Other considerations include the geometrical coordination environments around the metal centres and their comparison with isostructural congeners. The distortions around the metal centres and their subsequent effects on the symmetries of bonds in the primary and secondary coordination spheres are discussed. The trans-effects of secondary P-ligands and their effects on geometrical alignment and structural stability have become valuable yardsticks in analyzing structural modifications and stabilities.

This research is a Participatory Action Research (PAR) that aims to improve the understanding and practice of ibadah in the Kampung Batu Dalam, Solok district community. Research is carried out through several cycles of planning, action, observation, and reflection. In Cycle 1, diagnosis of problems is carried out through initial observation, identification of problems, analysis of root problems, and consultation with stakeholders. The lecture and learning methods were chosen as the initial action. Cycle 2 focuses on religious learning activities such as worship, sanctification, and sacrament and is taught to the community and children. The methods used include routine learning, competition, and active involvement of the community and children. Evaluations at Cycle 3 show success in raising children's spirits, but the main challenge is the difficulty of reaching older people who are still tied to the old tradition. The main findings of this study were the importance of combining an andragogic approach for the elderly and innovative game-based learning methods for children. Combining these two approaches is a creative and replicable solution to address similar problems in other societies with different characteristics.

Published: September 2024

Purpose. The goal of the study was to assess trends in providing food security with a special emphasis on efficiency of the local fisheries and offer evidence-based improvements, which can improve resource management and protect disadvantaged population in the Maldives from nutrition insecurity aggravated by strong import dependency.
Methodology / approach. The methodological basis of this study was a set of modern qualitative economic and quantitative mathematical methods including factor analyses, econometric and optimisation modelling. This approach ensured holistic research and reasonable recommendations on providing food security and maintaining efficient fisheries management compared to international experience and intrinsic aspects that determine a fish catch and consumption in the Maldives.
Results. The conclusions of the paper relate to the further development of fisheries to combat the identified negative trends in domestic fish consumption and an unstable fish catch by atoll in the Maldives. The conducted factor analysis detected relationships between a fish catch, fishing trips, engaged vessels, fish species, and fishing methods. The study findings proved the optimal locations where it is advisable to establish additional fish storages and ice plants taking into account indicators of a poverty rate, a share of children, and a population density. The research conclusions allow the authors to state that the outlined scientific proposals can essentially improve food security in the Maldives, which is threatened by land shortage and overpopulation.
Originality / scientific novelty. The scientific novelty of the work is in presenting a clarified picture of challenges that Maldivian fishermen face nowadays. The scientific novelty lies in the identification of weaknesses in fisheries management and the proposals of areas of potential growth that are crucial for ensuring food security not only on poor islands but for the whole country.
Practical value / implications. The main practical value of the research results is the development of recommendations for increasing fish catch and organising post-harvest processing, which are vital for the Maldivian fishery, as it is the country's main export sector. In addition, the study contributes to food security in the Maldives through proposed interventions aimed at supporting the most disadvantaged populations in the scattered atolls.

Impact of short- and long-term factors on the growth of gross agricultural products in Azerbaijan: ARDL analysis
Authors: Huseynov Maharram , Salahov Elchin , Niftaliyeva Rafiga
Published: September 2024

Purpose. The main purpose of this research is to assess the factors affecting the gross agricultural products in Azerbaijan in the short and long term.
Methodology / approach. This study uses an Autoregressive Distributional Lag (ARDL) model to analyse the relationship between gross agricultural output and total government expenditure on agriculture, the volume of credit used in agriculture, direct investment in fixed assets in agriculture, and the country’s net agricultural exports. In our study, unlike most existing research, the variables are integrated in the second order, which increases the importance of this study.
Results. The results of the study indicate that, despite the “crowding in” effect created by the state budget expenditures as the main factor in the short term, the effect on the growth of gross agricultural products in the long term is not so important. Credit resources and net exports have a negative effect in this relationship. In the long term, investment in fixed capital is a crucial factor in the growth of production. In general, the positive balance of net exports is a “mirror” reflection of investments, especially innovation-oriented investments. Considering that the predominance of imports in the total demand for agricultural products significantly reduces the multiplier effect that can occur in the field in general, it minimises the multiplier effect of the total expenditure. From this point of view, foreign investments can play an important role in creating a positive balance in the trade balance of agriculture.
Originality / scientific novelty. The scientific value of the research is the selection of main factors as direct contributions to the growth of the gross agricultural products and their effects. Through the ARDL program, we determined what factors are short-term and which are long-term, and we analysed the causes and consequences of these dependencies and put forward relevant proposals.
Practical value / implications. The practical value of the research lies in the given proposals that can directly affect the net export of agricultural products and create positive changes in its balance. Because, massive investments, especially foreign investments, can modernise the rural economy in a short period of time and, accordingly, not only increase the competitiveness of its products in foreign markets, but also raise the level of self-sufficiency.

Published: September 2024

Введение. В амбулаторных условиях педиатру и врачу общей практики важно своевременно определить показания и эмпирически назначить эффективный антибактериальный препарат. В Российской Федерации в течение последних лет разработаны и утверждены клинические рекомендации по различным болезням, определяющие показания к системной антибактериальной терапии, согласно которым при большинстве бактериальных острых респираторных инфекций стартовым препаратом является амоксициллин, а при неэффективности терапии или наличии лекарственно-устойчивых возбудителей рекомендуются ингибиторозащищенные аминопенициллины (амоксициллин/клавуланат). Заключение. В статье представлены определяющие показания к назначению антибактериальной терапии и особенности выбора стартового антибактериального препарата при таких инфекционно-воспалительных заболеваниях верхних дыхательных путей у детей, как острый тонзиллит и (или) фарингит, острый синусит, острый средний отит. Показано, что наиболее оптимальной лекарственной формой для применения антибактериальных препаратов являются диспергируемые таблетки, что повышает безопасность лечения и приверженность пациентов врачебным рекомендациям.

Background. In the outpatient setting, it is important for pediatricians and general practitioners to determine the indications and empirically prescribe an effective antibacterial drug in a timely manner. In the Russian Federation in recent years, clinical guidelines for various diseases have been developed and approved, defining indications for systemic antibacterial therapy, according to which amoxicillin is the starting drug for most bacterial acute respiratory infections, and inhibitor-protected aminopenicillins (amoxicillin/clavulanate) are recommended in case of ineffective therapy or drug-resistant pathogens. Conclusion. The article presents the determining indications for the prescription of antibacterial therapy and the peculiarities of the choice of the starting antibacterial drug in such infectious-inflammatory diseases of the upper respiratory tract in children as acute tonsillitis and/or pharyngitis, acute sinusitis, acute otitis media. It is shown that the most optimal dosage form for the use of antibacterial drugs is dispersible tablets, which increases the safety of treatment and patient adherence to medical recommendations.

Published: September 2024

Introdução: A criptorquidia, condição caracterizada pela não descida de um ou ambos os testículos para o escroto, é uma das anomalias genitais mais comuns em recém-nascidos e lactentes. O tratamento cirúrgico, geralmente por meio da orquidopexia, tem se mostrado essencial para prevenir complicações como infertilidade e câncer testicular. Estudos têm demonstrado que intervenções precoces podem resultar em melhor desenvolvimento funcional e psicológico dos pacientes. Entretanto, a análise dos resultados a longo prazo ainda suscita questões sobre a eficácia e as possíveis complicações associadas a essa cirurgia. Objetivo: Avaliar os resultados a longo prazo da cirurgia urológica no tratamento da criptorquidia em pacientes pediátricos. Metodologia: A pesquisa seguiu as diretrizes do checklist PRISMA e utilizou as bases de dados PubMed, Scielo e Web of Science. Foram empregados cinco descritores: "criptorquidia", "orquidopexia", "pediatria", "resultados a longo prazo" e "complicações". Os critérios de inclusão abrangeram artigos publicados nos últimos 10 anos, que abordaram pacientes pediátricos submetidos a cirurgia e que apresentaram resultados a longo prazo. Por outro lado, foram excluídos estudos com amostras pequenas, revisões não sistemáticas e artigos que não tratavam de resultados cirúrgicos. Resultados: A análise revelou que a orquidopexia realizada antes dos 12 meses esteve associada a melhores resultados funcionais, incluindo taxas reduzidas de infertilidade. Além disso, observou-se uma diminuição nas complicações cirúrgicas e psicológicas, como problemas de autoestima. A maioria dos estudos evidenciou que, mesmo após a cirurgia, o acompanhamento regular é crucial para detectar possíveis anomalias. Conclusão: A cirurgia urológica para tratamento da criptorquidia em pacientes pediátricos mostrou-se eficaz e essencial, com resultados positivos a longo prazo, desde que realizada precocemente. Os dados ressaltaram a importância do manejo adequado e do acompanhamento contínuo para garantir a saúde e o bem-estar dos pacientes, além de minimizar riscos futuros. As evidências apoiaram a necessidade de intervenções cirúrgicas precoces e o monitoramento contínuo dos indivíduos afetados.
Nonparametric estimation of age-depth models from sedimentological and stratigraphic information
Authors: Hohmann Niklas , De Vleeschouwer David , Batenburg Sietske , Jarochowska Emilia
Published: September 2024

Abstract. Age-depth models are fundamental tools used in all geohistorical disciplines. They assign stratigraphic positions to ages (e.g., in drill cores or outcrops), which is necessary to estimate rates of past environmental change and establish timing of events in sedimentary sequences. Methods to estimate age-depth models commonly use simplified parametric assumptions on the uncertainties of ages of tie points. The distribution of time between tie points is estimated using simplistic assumptions on the formation of the stratigraphic record, for example that sediment accumulates in discrete events that follow a Poisson process. In general, age-depth models are a crude simplification that fail to provide a comprehensive implementation of all empirical data or expert knowledge (e.g., from sedimentary structures such as erosional surfaces or from basin models). In other words, many information sources that can potentially provide geochronologic information remain un- or underused. Here, we present two non-parametric methods to estimate age-depth models from complex sedimentological and stratigraphic data. The methods are complementary as they use different sources of information (sedimentation rates and observed tracer values), are implemented in the admtools package for R Software and allow the user to specify any error model and distribution of uncertainties. As use cases of the methods, we construct age-depth models for the Late Devonian Steinbruch Schmidt section in Germany and use it to estimate the timing of the Frasnian-Famennian boundary and the duration of the Upper Kellwasser event. use measurements of extra-terrestrial 3He from ODP site 960 (Maud Rise, Weddell Sea) to construct age-depth models for the Paleocene–Eocene thermal maximum (PETM). The first case study suggests that the Upper Kellwasser event lasted 89 kyr (IQR: 84 to 97 kyr) and places the Frasnian-Famennian boundary at 371.834 ± 0.101 Ma (2 σ), whereas the second case study provides a duration of 41 to 48 kyr for the PETM recovery interval. These examples show how information from a variety of sedimentological and stratigraphic sources can be combined to estimate age-depth relationships that accurately reflect uncertainties of both available data and expert knowledge.

Abstract. Commercial supersonic aircraft may return in the near future, offering reduced travel times while flying higher in the atmosphere than present-day aircraft. Their emissions can change the composition of the atmosphere, particularly in the concentration and spatial distribution of ozone, aerosols, and greenhouse gases, posing risks to both the climate and public health. We present a comprehensive multi-model assessment of the impact of a supersonic fleet on a 2050 atmosphere using four state-of-the-art atmospheric models (EMAC, GEOS-Chem, LMDZ-INCA, MOZART-3). We show that the adoption of a fleet with a NOx emissions index of 4.6 g(NO2)/kg(fuel) leads to a model-mean stratospheric H2O burden of +61.34 Tg for 46.2 Tg of annual H2O emissions, and an ozone column loss of -0.11 %. With a NOx emissions index of 13.8 g(NO2)/kg(fuel) the average ozone column loss increases to -0.31 %. A lower cruise altitude and speed reduces the mean H2O burden to +9.34 Tg and instead leads to an ozone column increase of +0.02 %. Compared to the most recent multi-model assessment (2007), we find better agreement between the models, especially for the ozone response. Disagreement in H2O perturbation lifetimes remains, potentially driven by differences in vertical model resolutions. Our results reaffirm that emissions from a supersonic aircraft fleet will lead to global changes in atmospheric composition, which can be reduced by adopting lower cruise altitudes and lowering NOx emissions.

Abstract. Mineral-organic associations are crucial carbon and nutrient reservoirs in soils. However, soil cultivation disrupts these associations, leading to carbon loss and reduced soil fertility. Although, identifying the specific type(s) of mineral-organic associations susceptible to destruction or transformation upon cropping remains challenging, it is essential for devising strategies to preserve organic matter in croplands. Here we aimed to determine the predominant mineral-organic associations and to identify which types of associations are transformed upon cultivation. To achieve this, we sampled an andosol from both a forested and a cultivated area. We then analyzed cultivation-induced changes in soil physicochemical parameters and characterized mineral-organic associations using an array of spectro-microscopic techniques (TEM-EDX, TEM-EELS, and STXM), for comprehensive structural and compositional analysis. At the micro and nanoscale, we observed mineral-organic associations in the form of coprecipitates composed of amorphous oligomers containing Al, Si, and Fe (referred to as nanoCLICs for nanosized coprecipitates of inorganic oligomers with organics). Down to a few hundred nanometers, the nanoCLICs displayed elemental enrichments with C+Al+Si, C+Fe+Al+Si, or Al+Si dominance with less C. In contrast, organic matter exhibited various C speciation without compound-specific enrichments. These findings suggest that mineral-organic associations in andosols are nanoCLICs-type coprecipitates rather than organic matter associated solely with secondary minerals. NanoCLICs were present in both forest and crop andosols, and while cropping led to a 50 % decrease in nanoCLICs, it did not alter their nature. This novel conceptualization of mineral-organic associations as nanoCLICs shifts our understanding of their persistence in andosols and demonstrates their vulnerability to crop-induced changes.

Abstract. Debris flows, as a special kind of landslides, often block rivers to form barrier dams and trigger a series of disasters such as upstream aggradation and outburst floods. The understanding of debris-flow barrier dams (DFBDs) is poor, mostly due to existing researches focusing on individual events and a lack of summarization of multiple DFBD events. The existing global or regional datasets of landslide barrier dams (LDs) contain only a few cases of DFBDs, and ignore the differences between DFBDs and other landslide barrier dams (LDs), such as the dams of rock slide, debris avalanche, or earth slide. To fill this gap, we reviewed 2519 literatures and media reports with high quality. Focusing on identified debris-flow damming events, a rigorous data review and validation process was conducted using Google Earth. A systematic approach was employed to prioritize conflicting information from various data sources. Consequently, a global dataset was compiled, encompassing 555 historical DFBDs from 1800 to 2023. This pioneering global dataset includes five categories and 36 attributes, detailing DFBDs. It captures basic information (location, the date of formation, etc.), dam characteristics (height, length, volume, etc.), lake characteristics (area, capacity, length), debris flow characteristics (velocity, discharge, volume, etc.), and failure characteristics (peak discharge, loss of life, etc.). Our dataset elucidates that DFBDs exhibit key features of instability, complete blockage, and overtopping failure. The number of such dams has notably increased, especially in China. 15 % of channels showed recurrent debris flows, resulting in DFBDs that make up 35 % of all DFBDs. Further analysis recommends the Ls (AHV) model is recommended for priority use, followed by the DBI model, for the stability assessment of DFBDs. Compared to other barrier dam datasets, our dataset is more targeted, lays a greater emphasis on the review of raw data, and stresses the unification of terminology and concepts (such as blockage modes and stability), ensuring the consistency and accuracy of the data. The dataset and results in this work may help to deepen the understanding of DFBD formation, distribution, and evolution.

Abstract. This paper presents a model intercomparison study to improve the prediction and understanding of Mediterranean cyclone dynamics. It is based on a collective effort with five mesoscale models to look for a robust response among 10 numerical frameworks used in the community involved in the networking activity of the EU COST Action “MedCyclones”. The obtained multi-model, multi-physics ensemble is applied to the high-impact Medicane Ianos of September 2020 with a focus on the cyclogenesis phase, which was poorly forecast by numerical weather prediction systems. Models systematically perform better when initialised from operational IFS analysis data compared to the widely used ERA5 reanalysis. Reducing horizontal grid spacing from 10 km with parameterised convection to convection-permitting 2 km further improves the cyclone track and intensity. This highlights the critical role of deep convection during the early development stage. Higher resolution enhances convective activity, which improves the phasing of the cyclone with an upper-level jet and its subsequent intensification and evolution. This upscale impact of convection matches a conceptual model of upscale error growth in the midlatitudes, while it emphasises the crucial interplay between convective and baroclinic processes during medicane cyclogenesis. The 10 numerical frameworks show robust agreement but also reveal model specifics that should be taken into consideration, such as the need for a parameterisation of deep convection even at 2 km horizontal grid spacing in some models. While they require generalisation to other cases of Mediterranean cyclones, the results provide guidance for the next generation of global convection-permitting models in weather and climate.

Sistem kemudi merupakan salah satu komponen yang harus ada pada kapal, karena dalam penentuan arah yang diinginkan dikendalikan oleh sistem ini. Pada kemudi terdapat daun kemudi (rudder blade) dan poros kemudi (rudder stock). Pentingnya peran kemudi kapal pada proses pelayaran sehingga  perlu dilakukan analisis terhadap posisi kerja pengemudi kapal guna meminimasi resiko terjadinya muskuloskeletal disorder. Penelitian dilakukan dengan observasi beberapa calon nahkoda dalam laboratorium simulator Akademi Maritim Nusantara Cilacap. Analisis dilakukan dengan menggunakan pendekatan Rapid Entire Body Asesment (REBA) dan Antropometri. Hasil penelitian menunjukan posisi kerja seorang pekerja merupakan hal yang penting untuk diperhatikan agar terciptanya kenyamanan dalam bekerja dan mengurangi terjadinya resiko cedera seperti musculoskeletal disorder. Analisis pada operator kemudi kapal pada ruang simulator Akademi Maritim Nusantara Cilacap menggunakan REBA (Rapid Entire Body Assesment) dihasilkan nilai sebesar 4, maka dapat disimpulkan bahwa posisi kerja dalam tingkat resiko yang sedang dan perlu adanya perbaikan. Usulan rancangan perbaikan kemudi kapal pada ruang simulator Akademi Maritim Nusantara Cilacap yaitu menggunakan acuan antropometri yang dilakukan pada 30 Taruna. Pengukuran dimensi tubuh dan persentil yang diterapkan sebagai acuan usulan rancangan ruang kemudi kapal dihasilkan sebagai berikut: (1) persentil 50th digunakan pada ukuran eye height (tinggi pandangan mata pada jendela kapal), elbow (Tinggi tuas throtle dan tinggi pegangan roda kemudi dari lantai), hip height (tinggi roda kemudi dari lantai), (2) persentil 5th digunakan untuk ukuran Dgmin (diameter tuas throtle) dan Dgmak (diameter roda kemudi).
Perbandingan Pengaruh Penambahan Sponge dan Coconut Fiber pada Air Cooler Pengganti Air Conditioning di Kapal Papua Jaya Karya
Authors: Purnomo Yohanes R.
Published: September 2024

Penelitian eksperimental ini membandingkan kinerja pendinginan air cooler dengan penambahan media pendingin berupa coconut fiber dan sponge. Tujuan penelitian ini adalah untuk menganalisis efisiensi penurunan suhu udara pada berbagai kecepatan aliran udara dengan menggunakan kedua jenis media pendingin tersebut. Hasil penelitian menunjukkan bahwa penambahan sponge memberikan kinerja pendinginan yang lebih baik dibandingkan dengan penambahan coconut fiber pada semua variasi kecepatan aliran udara yang diuji. Hal ini dapat dijelaskan oleh karakteristik fisik sponge yang memiliki banyak pori – pori lebih halus dan luas, sehingga mampu menyerap air lebih banyak dan memperluas permukaan kontak antara air dan udara. Selain itu, sponge memiliki daya kapilaritas yang lebih tinggi, memungkinkan distribusi air secara merata pada seluruh permukaan media pendingin. Sebaliknya, coconut fiber memiliki struktur yang lebih kasar dan daya serap yang lebih rendah, sehingga kurang efektif dalam menyerap dan menguapkan air. Dengan demikian, penggunaan sponge sebagai media pendingin pada air cooler berpotensi meningkatkan efisiensi pendinginan dan memberikan kenyamanan termal yang lebih baik.

Acercarnos a las movilidades humanas es saber que las teorías, sus conceptos y abordajes van más allá de postulados. Los desplazamientos no solo son números que pueden transformarse en reportes, informes o posibles posicionamientos de políticas públicas; las movilidades humanas son vidas que se transforman, espacios que son dejados, transitados y arribados; las movilidades modifican nuestros preceptos del transitar espacios impenetrables. Las movilidades humanas hoy nos dejan una gran tarea, pues no solo debemos verlas y estudiarlas, sino que debemos particularizarlas y sensibilizarnos a sus causas y a los impactos que conllevan en su andar, y, sobre todo, dirigir la mirada hacia una correcta concepción del andar. Para ello, los abordajes metodológicos que tomemos serán de vital importancia. Por ejemplo, el análisis discursivo de las narrativas, de los imaginarios; la relación de sus variables económicas, sociales y políticas; la importancia de sus procesos históricos, sus herencias, los impactos en la salud, en la cultura; atender sus causales ambientales, territoriales. Pero, sobre todo, hay que posicionar las miradas y discursos desde una perspectiva de entendimiento. Con base en lo anterior, y en aras de seguir fortaleciendo los abordajes hacia las movilidades humanas, la presente obra es el resultado de un trabajo teórico y metodológico que ha surgido de la pregunta “¿Cómo entender las movilidades humanas ante los actuales sentidos y contrasentidos que han querido limitarlas?”. Para ello, hay que destacar las distintas formas en las que se han visto rebasados los territorios y sus fronteras, ya que esto permitió a los autores que participan en esta obra ofrecer distintas respuestas a nuestra pregunta.
