Authors: Khairi Mhd Galih , Muhammad Irfan Gurning  , Mhd. Furqan
Published: September 2024

Air conditioning has become essential in the modern era, with nearly everyone worldwide owning an air conditioner in their homes. Its presence is crucial given the increasingly hot weather conditions due to global warming. However, we often forget to turn off the air conditioner, resulting in energy waste and potential damage to the device. Therefore, this writing aims to address these issues through the development of an automatic system using Arduino Nano, programmed in the C language, to regulate the operation of the air conditioner based on room temperature. This way, users do not need to bother manually turning the air conditioner on or off using a remote control or buttons.
TRADISI PERNIKAHAN MELANGKAHI KAKAK KANDUNG DALAM PERSPEKTIF HUKUM ISLAM DI KELURAHAN JATI WARINGIN
Authors: Gunawan Tri , Adhim Fauzan
Published: September 2024

Keyakinan masyarakat Jati Waringin tentang dampak dari pernikahan melangkahi kakak kandung tidak memiliki dasar yang jelas melainkan merupakan budaya-budaya lisan yang turun temurun yang masih dilestarikan, karena adanya fakta yang menyerupai dampak yang ditakutkan tersebut, hal yang seperti itu bisa saja merupakan suatu hal yang kebetulan, bisa saja terjadi pada siapapun walaupun tidak dengan pernikahan dengan melangkahi kakak kandung. Larangan menikah sebelum kakak menikah boleh saja dilanggar, karena juga terlihat ada masyarakat yang melanggar. Namun tidak berdampak apa-apa pada rumah tangganya dan tidak seperti yang dikhawatirkan tersebut. Dalam hal meminta izin kepada orang tua atau kepada kakak hal itu hal yang wajar, sebagai bentuk kesopanan adik terhadap kakak kandungnya. Selain yang tercantum dalam mahrom nikah semuanya boleh di nikahi jika memenuhi syarakat dan rukun nikah.
Le cosmos est-il le visage de Dieu ?
Authors: Perron Louis
Published: September 2024

Le discours cosmologique actuel permet-il d’affirmer le caractère théophanique du cosmos, au sens où celui-ci pourrait être considéré comme le lieu de la manifestation visible et immédiate de Dieu ? Plus généralement : est-il en mesure d’ouvrir un chemin vers la foi ? Contrairement à un discours récurrent, l’auteur, s’appuyant sur l’oeuvre de Jean Ladrière, défend la thèse qu’il n’existe pas de voie royale conduisant de la science à la foi. Celle-ci peut cependant recueillir l’image scientifique du monde et lui conférer une signification propre, moyennant un parcours herméneutique s’appuyant sur l’articulation des différents registres de sens et dont la médiation philosophique constitue le passage obligé.
Y a-t-il dans la Bible un biais « validiste » contre les femmes porteuses de handicap ?

Published: September 2024

Cet article pose une question nouvelle : Y a-t-il dans la Bible un biais « validiste » contre les femmes porteuses de handicap ? Les auteures répondent par un prudent « oui, mais… ». Toutefois, la réception des textes qui évoquent des situations de handicap commence à changer. Cette étude est une illustration de ce changement en cours.
« J’attends vos lumières de tous » : collégialité et délibérations d’appel à la Cour du banc de la Reine/du Roi, 1891-1907
Authors: Bich-Carrière Julien
Published: September 2024

La littérature juridique moderne s’est intéressée à la collégialité des tribunaux et aux processus décisionnels qui s’y rattachent. Cependant, contrairement à d’autres pans de l’activité judiciaire, la dimension historique du phénomène, au Québec, est encore largement inexplorée. C’est ce sujet qu’aborde l’auteur en proposant une réflexion sur la culture de la collégialité entre juges et en examinant à cette fin le fonctionnement de la Cour du banc de la Reine/du Roi du Québec à l’époque où elle est dirigée par le juge en chef sir Alexandre Lacoste. Cette institution structurellement collégiale est en effet un modèle de collégialité délibérative, doublée d’une forte collégialité informelle. Les documents qu’elle a laissés en donnent maints exemples, qui permettent de saisir comment les pratiques internes d’un tribunal, souvent méconnues, influencent la qualité de son fonctionnement et de ses jugements, renforçant ainsi l’administration de la justice.
La modification de la Charte des droits et libertés de la personne en débats
Authors: Bourgeois Oscar , Leckey Robert
Published: September 2024

Dans le présent texte, les auteurs offrent une analyse qualitative du Journal des débats. Ils rendent compte de la conversation parlementaire au sujet de la modification de la Charte des droits et libertés de la personne, de sa création en 1975 jusqu’en 2022. Durant cette période, les élus ont apporté de nombreuses modifications à cet instrument quasi constitutionnel avec l’appui de tous les bancs de l’Assemblée nationale du Québec. Les députés ont longtemps souscrit à la pratique de modification par consensus, conférant à la Charte une légitimité et une autorité morale accrues. Ils ne se sentaient cependant pas liés par cette pratique, qui ne relève donc pas d’une convention constitutionnelle. En 2019 et en 2022, l’adoption de modifications importantes dans le contexte de lois largement rejetées par l’opposition interrompt la pratique consensuelle. Le statut de la Charte comme projet collectif des élus québécois est en jeu dès lors que l’exercice du pouvoir de la majorité supplante la recherche d’un consensus.

Published: September 2024

The snow vole is a glacial relic that currently has a highly fragmented distribution spread throughout the south-western paleartic region. It is found in rocky habitats, such as scree, usually at the top of the main mountain ranges. There are five main population nuclei in the Iberian Peninsula. These populations are located in: the Pyrenees, the Cantabrian, Iberian and Central Systems, and the Sierra Nevada mountain ranges. The Sierra Nevada National and Natural Parks represent the most south-western limit of its distribution area; however, this population has not been well studied. This study provides an update on the historically known distribution of the snow vole in the Sierra Nevada National and Natural Parks. The study area was subdivided into 10x10 km UTM grids. Stratified sampling was conducted focusing on potential patches of habitats for the snow vole. Both direct and indirect sampling methods were applied. A total of 100 potential localities were sampled in the study area verifying the presence of snow voles in 75% of them. This study examines the presence of the snow vole in its former known distribution areas in the park, maps and details new locations within these areas, and extends the distribution range in the Sierra Nevada due to the discovery of its presence in six new grids.

In this study, we investigated the role of 17α-estradiol in lifespan extension and its potential side effects from long-term administration. Pooled hypothalami from aged male Norway brown rats treated with 17α-estradiol (O.T), aged male controls (O), and young male controls (Y) were subjected to single-nucleus transcriptomic sequencing (snRNA-seq). To evaluate the effects of 17α-estradiol on aging neurons, supervised clustering of neurons based on neuropeptides and their receptors were used to evaluate the responses of each neuron subtype during aging and after 17α-estradiol treatment. The elevated cellular metabolism, stress and decreased expression levels of pathways involved in synapse formation in neurons initiated by aging were significantly attenuated by 17α-estradiol. Assessment of changes in neuron populations showed that neurons related to food intake, reproduction, blood pressure, stress response, and electrolyte balance were sensitive to 17α-estradiol treatment. 17α-estradiol treatment not only increased serum Oxytocin (Oxt), but also heightened the activity of hypothalamic-pituitary-gonadal (HPG) axis, as evidenced by significantly elevated levels of plasma Gnrh, total testosterone, and decreased estradiol. Elevated Gnrh1 was confirmed to be one of the causal effects mediating the role of 17α-estradiol in energy homeostasis, neural synapse, and stress response. Notably,
Crh
neurons exhibited prominent stressed phenotype among all the checked neuron subtypes in O.T, which may indicate a potential side effect of 17α-estradiol treatment. Therefore, the HPG axis and energy metabolism may be key targets of 17α-estradiol in male hypothalamus. Additionally, supervised clustering of neurons was shown to be a useful method for assessing treatment responses among different neuron subtypes in the hypothalamus.
Translatome analysis reveals cellular network in DLK-dependent hippocampal glutamatergic neuron degeneration

Published: September 2024

The conserved MAP3K12/Dual Leucine Zipper Kinase (DLK) plays versatile roles in neuronal development, axon injury and stress responses, and neurodegeneration, depending on cell-type and cellular contexts. Emerging evidence implicates abnormal DLK signaling in several neurodegenerative diseases. However, our understanding of the DLK-dependent gene network in the central nervous system remains limited. Here, we investigated the roles of DLK in hippocampal glutamatergic neurons using conditional knockout and induced overexpression mice. We found that dorsal CA1 and dentate gyrus neurons are vulnerable to elevated expression of DLK, while CA3 neurons appear less vulnerable. We identified the DLK-dependent translatome that includes conserved molecular signatures and displays cell-type specificity. Increasing DLK signaling is associated with disruptions to microtubules, potentially involving STMN4. Additionally, primary cultured hippocampal neurons expressing different levels of DLK show altered neurite outgrowth, axon specification, and synapse formation. The identification of translational targets of DLK in hippocampal glutamatergic neurons has relevance to our understanding of selective neuron vulnerability under stress and pathological conditions.
Multiple origins of dorsal ecdysial sutures in trilobites and their relatives

Published: September 2024

Euarthropods are an extremely diverse phylum in the modern, and have been since their origination in the early Palaeozoic. They grow through moulting the exoskeleton (ecdysis) facilitated by breaking along lines of weakness (sutures). Artiopodans, a group that includes trilobites and their non-biomineralizing relatives, dominated arthropod diversity in benthic communities during the Palaeozoic. Most trilobites – a hyperdiverse group of tens of thousands of species - moult by breaking the exoskeleton along cephalic sutures, a strategy that has contributed to their high diversity during the Palaeozoic. However, the recent description of similar sutures in early diverging non-trilobite artiopodans mean that it is unclear whether these sutures evolved deep within Artiopoda, or convergently appeared multiple times within the group. Here we describe new well-preserved material of
Acanthomeridion
, a putative early diverging artiopodan, including hitherto unknown details of its ventral anatomy and appendages revealed through CT scanning, highlighting additional possible homologous features between the ventral plates of this taxon and trilobite free cheeks. We used three coding strategies treating ventral plates as homologous to trilobite free cheeks, to trilobite cephalic doublure, or independently derived. If ventral plates are considered homologous to free cheeks,
Acanthomeridion
is recovered sister to trilobites however dorsal ecdysial sutures are still recovered at many places within Artiopoda. If ventral plates are considered homologous to doublure or non-homologous, then
Acanthomeridion
is not recovered as sister to trilobites, and thus the ventral plates represent a distinct feature to trilobite doublure/free cheeks.

The exchange of metabolites (i.e., metabolic interactions) between bacteria in the rhizosphere determines various plant-associated functions. Systematically understanding the metabolic interactions in the rhizosphere, as well as in other types of microbial communities, would open the door to the optimization of specific pre-defined functions of interest, and therefore to the harnessing of the functionality of various types of microbiomes. However, mechanistic knowledge regarding the gathering and interpretation of these interactions is limited. Here, we present a framework utilizing genomics and constraint based modeling approaches, aiming to interpret the hierarchical trophic interactions in the soil environment. 243 genome-scale metabolic models of bacteria associated with a specific disease suppressive vs disease conducive apple rhizospheres were drafted based on genome resolved metagenomes, comprising an
in-silico
native microbial community. Iteratively simulating microbial community members’ growth in a metabolomics-based apple root-like environment produced novel data on potential trophic successions, used to form a network of communal trophic dependencies. Network-based analyses have characterized interactions associated with beneficial vs non-beneficial microbiome functioning, pinpointing specific compounds and microbial species as potential disease supporting and suppressing agents. This framework provides a means for capturing trophic interactions and formulating a range of testable hypotheses regarding the metabolic capabilities of microbial communities within their natural environment. Essentially, it can be applied to different environments and biological landscapes, elucidating the conditions for the targeted manipulation of various microbiomes, and the execution of countless predefined functions.
Chemokine expression profile of an innate granuloma

Published: September 2024

Granulomas are defined by the presence of organized layers of immune cells that include macrophages. Granulomas are often characterized as a way for the immune system to contain an infection and prevent its dissemination. We recently established a mouse infection model where
Chromobacterium violaceum
induces the innate immune system to form granulomas in the liver. This response successfully eradicates the bacteria and returns the liver to homeostasis. Here, we sought to characterize the chemokines involved in directing immune cells to form the distinct layers of a granuloma. We use spatial transcriptomics to investigate the spatial and temporal expression of all CC and CXC chemokines and their receptors within this granuloma response. The expression profiles change dynamically over space and time as the granuloma matures and then resolves. To investigate the importance of monocyte-derived macrophages in this immune response, we studied the role of CCR2 during
C. violaceum
infection.
Ccr2
−/−
mice had negligible numbers of macrophages, but large numbers of neutrophils, in the
C. violaceum
-infected lesions. In addition, lesions had abnormal architecture resulting in loss of bacterial containment. Without CCR2, bacteria disseminated and the mice succumbed to the infection. This indicates that macrophages are critical to form a successful innate granuloma in response to
C. violaceum
.

HER2 overexpression significantly contributes to the aggressive nature and recurrent patterns observed in various solid tumors, notably gastric cancers. Trastuzumab, HER2-targeting monoclonal antibody drug, has shown considerable clinical success, however, readily emerging drug resistance emphasizes the pressing need for improved interventions in HER2-overexpressing cancers. To address this, we proposed targeting the protein-protein interaction (PPI) between ELF3 and MED23 as an alternative therapeutic approach to trastuzumab. In this study, we synthesized a total of 26 compounds consisting of 10 chalcones, 7 pyrazoline acetyl, and 9 pyrazoline propionyl derivatives, and evaluated their biological activity as potential ELF3-MED23 PPI inhibitors. Upon systematic analysis, candidate compound
10
was selected due to its potency in downregulating reporter gene activity of HER2 promoter confirmed by SEAP activity and its effect on HER2 protein and mRNA levels. Compound
10
effectively disrupted the binding interface between the ELF3 TAD domain and the 391-582 amino acid region of MED23, resulting in successful inhibition of the ELF3-MED23 PPI. This intervention led to a substantial reduction in HER2 levels and its downstream signals in the HER2-positive gastric cancer cell line. Subsequently, compound
10
induced significant apoptosis and anti-proliferative effects, demonstrating superior
in vitro
and
in vivo
anticancer activity overall. We found that the anticancer activity of compound
10
was not only restricted to trastuzumab-sensitive cases, but was also valid for trastuzumab-refractory clones. This suggests its potential as a viable therapeutic option for trastuzumab-resistant gastric cancers. In summary, compound
10
could be a novel alternative therapeutic strategy for HER2-overexpressing cancers, overcoming the limitations of trastuzumab.
Visual information is broadcast among cortical areas in discrete channels
Authors: Yu Yiyi , Stirman Jeffery N , Dorsett Christopher R , Smith Spencer LaVere
Published: September 2024

Among brain areas, axonal projections carry channels of information that can be mixed to varying degrees. Here, we assess the rules for the network consisting of the primary visual cortex and higher visual areas (V1-HVA) in mice. We use large field-of-view two-photon calcium imaging to measure correlated variability (i.e., noise correlations, NCs) among thousands of neurons, forming over a million unique pairs, distributed across multiple cortical areas simultaneously. The amplitude of NCs is proportional to functional connectivity in the network, and we find that they are robust, reproducible statistical measures, and are remarkably similar across stimuli, thus providing effective constraints to network models. We used these NCs to measure the statistics of functional connectivity among tuning classes of neurons in V1 and HVAs. Using a data-driven clustering approach, we identify approximately 60 distinct tuning classes found in V1 and HVAs. We find that NCs are higher between neurons from the same tuning class, both within and across cortical areas. Thus, in the V1-HVA network, mixing of channels is avoided. Instead, distinct channels of visual information are broadcast within and across cortical areas, at both the micron and millimeter length scales. This principle for the functional organization and correlation structure at the individual neuron level across multiple cortical areas can inform and constrain computational theories of neocortical networks.
Should I stay or should I go? Spatio-temporal dynamics of bacterial biofilms in confined flows

Published: September 2024

The vast majority of bacteria live in sessile biofilms that colonize the channels, pores and crevices of confined structures. Flow in these structures carries the nutrients necessary for growth, but also generates stresses and detachment from surfaces. Conversely, bacteria tend to occupy a large part of the available space and, in so doing, increase resistance to flow and modify transport properties. Although the importance of advective transport and hydrodynamic forces on bacteria is well known, the complex feedback effects that control development in confined geome-tries are much less understood. Here, we study how couplings between flow and bacterial development control the spatio-temporal dynamics of
Pseudomonas aeruginosa
in microchannel flows. We demonstrate that nutrient limitation drives the longitudinal distribution of biomass, while a competition between growth and flow-induced detachment controls the maximum clogging and the temporal dynamics. We find that successive cycles of sloughing and growth cause persistent fluctuations of the hydraulic resistance and prevent the system from ever reaching a true steady-state. Our results indicate that these self-sustained fluctuations are a signature effect of biofilm development in confined flows and could thus be a key component of the spreading of biofilms in infections, environmental processes and engineering applications. Consistent with the description of other bursting events, such as earthquakes or avalanches, we further show that the dynamics of sloughing can be described as a jump stochastic process with a gamma distribution of interevent times. This stochastic modeling approach opens the way towards a new quantitative approach to the characterization of the apparent randomness and irreproducibility of biofilm experiments in such systems.
α/β-Hydrolase domain-containing 6 (ABHD6) accelerates the desensitization and deactivation of TARP γ-2-containing AMPA receptors

AMPA receptors (AMPARs) mediate most of the fast excitatory synaptic transmission in mammalian brain. Their efficacy in responding to presynaptic glutamate release depends on their kinetics, which are determined by AMPARs and their auxiliary subunit composition. α/β-Hydrolase domain-containing 6 (ABHD6) is an AMPAR auxiliary subunit that has been shown to negatively regulate the surface delivery of AMPARs and AMPAR-mediated currents. Overexpression of ABHD6 decreased the rising slope and increased the decay τ of mEPSCs. However, whether ABHD6 is involved in regulating AMPAR kinetics remains unclear. Here, we found that ABHD6 per se had no effects on the gating kinetics of GluA1 and GluA2(Q) containing homomeric receptors. However, in the presence of the auxiliary subunit TARP γ-2, ABHD6 accelerated the deactivation and desensitization of either GluA1 and GluA2(Q) containing homomeric receptors independent of their splicing isoforms (flip and flop) and the editing isoforms of GluA2 (R or G at position 764), except the deactivation of GluA2(Q)i-G isoform. Besides, the recovery from desensitization of GluA1 with flip splicing isoform was slowed by the co-expression of ABHD6 in the presence of TARP γ-2. Furthermore, the ABHD6 accelerated the deactivation and desensitization of GluA1i/GluA2(R)i-G heteromeric receptors in the presence of TARP γ-2. Therefore, these results demonstrate that ABHD6 regulates AMPAR gating kinetics in a TARP γ-2-dependent manner.

Outdoor recreation has experienced a boom in recent years and continues to grow. While outdoor recreation provides wide-ranging benefits to human well-being, there are growing concerns about the sustainability of recreation with the increased pressures placed on ecological systems and visitor experiences. These concerns emphasize the need for managers to access accurate and timely recreation data at scales that match the growing extent of the recreation footprint. Here, we compare spatial and temporal patterns of winter and summer recreation using traditional (trail cameras, infrared counters, aerial surveys, participatory mapping) and application-based tools (Strava Metro, Strava Global Heatmap, Wikiloc) across the Columbia and Canadian Rocky Mountains of western Canada. We demonstrate how recreation use can be estimated using traditional and application-based tools, although their accuracy and utility varies across space, season and activity type. We found that trail cameras and infrared counters captured similar broad-scale patterns in count estimates of pedestrians and all recreation activities. Aerial surveys captured areas with low recreation intensity and participatory mapping captured coarser information on the intensity and extent of recreation across large spatial and temporal scales. Application-based data provided detailed spatiotemporal information on recreation use, but datasets were biased towards specific activities. Strava Metro data was more suited for capturing broad-scale spatial patterns in biking than pedestrian recreation. Application-based data should be supplemented with data from traditional tools to identify biases in data and fill in data gaps. We provide a comparison of each tool for measuring recreation use, highlight each tools’ strengths and limitations and applications to address real-world monitoring and management scenarios. Our research contributes towards a better understanding of which tool, or combinations of tools, to use that can expand the rigor and scope of recreation research. These findings support decision-making to mitigate pressures on wildlife and their habitats while allowing for high-quality recreation experiences.

Published: September 2024

Acute lung injury (ALI) is one of the most deadly and prevalent diseases in the intensive care unit. Ferroptosis and mitophagy are pathological mechanisms of ALI. Ferroptosis aggravates ALI, whereas mitophagy regulates ALI. Ferroptosis and mitophagy are both closely related to reactive oxygen species (ROS). Mitophagy can regulate ferroptosis, but the specific relationship between ferroptosis and mitophagy is still unclear. This study summarizes previous research findings on ferroptosis and mitophagy, revealing their involvement in ALI. Examining the functions of mTOR and NLPR3 helps clarify the connection between ferroptosis and mitophagy in ALI, with the goal of establishing a theoretical foundation for potential therapeutic approaches in the future management of ALI.

Power system optimization and sub-hourly simulation of solar photovoltaic plants with battery energy storage systems considering ancillary services
Authors:   , Ibarra Alemany Martín Felipe
Published: September 2024

La integracióon de fuentes de energía renovable variable en la red eléctrica presenta desafíos y oportunidades significativos. Entre las soluciones más prometedoras se encuentra el despliegue de Sistemas de Almacenamiento de Energía con Baterías, que pueden ofrecer múltiples servicios. Su instalación se ha visto obstaculizada por desafíos regulatorios y altos costos, los cuales están disminuyendo año tras año. Este trabajo examina los marcos regulatorios, los incentivos del mercado y las métricas operativas y financieras necesarias para hacer que las plantas de energía solar fotovoltaica con BESS sean económicamente viables. Se propone un modelo operativo en dos etapas de una red eléctrica que considera reservas, la instalación de baterías y la expansión de plantas PV existentes, utilizando también como entrada la carga y el estado de las baterías basado en un modelo de simulación PV+BESS usando el software System Advisor Model, para incorporar las no linealidades de BESS. El modelo se prueba con la red eléctrica chilena, con 26 nodos para la etapa de instalación de BESS y 212 para la etapa de operación. Al abordar estos factores, la investigación busca proporcionar información sobre cómo las plantas PV+BESS pueden integrarse efectivamente en el mercado energético, apoyando en última instancia la adopción más amplia de tecnologías de energía renovable. Los resultados muestran que, bajo los marcos regulatorios y de remuneración considerados, la ubicación no afecta significativamente la viabilidad económica, las soluciones favorecidas por el ISO pueden no ser adecuadas para los operadores de plantas, la degradación varía significativamente entre plantas y escenarios, y hay factores importantes a considerar al diseñar plantas PV+BESS en tales mercados, como la probabilidad de activación de reservas.
Dinámicas de Credibilidad en Estadísticas Oficiales de Pobreza: Construcción del Índice de Pobreza Multidimensional Chileno
Authors:   , Delgado Muñoz Nicolás Sebastián
Published: September 2024

Debido a los cuantiosos recursos necesarios para computar índices oficiales de pobreza es imperante que gocen de alta credibilidad pública para validar su uso como evidencia. Por ende, es necesario que sean percibidos como ‘fácticos’. En otras palabras, la credibilidad de un índice depende de que sus resultados sean concebidos como ‘objetivos’. El presente trabajo, a partir de literatura sobre cuantificación y Teoría del Actor-Red, busca problematizar la credibilidad de las estadísticas oficiales; mediante la construcción y análisis de un corpus documental y entrevistas a personas clave durante el diseño e implementación del Índice de Pobreza Multidimensional chileno desde 2012 a 2018. En particular, el año 2012 se acusó al gobierno de turno de manipular el principal estadístico que cuantifica el nivel de pobreza a nivel país, lo que derivó en la pérdida de su credibilidad. Por tanto, el gobierno decidió, inéditamente desde 1990, actualizar la metodología empleada para calcular la pobreza nacional. No obstante, tuvieron que pasar seis años y cuatro iteraciones del índice para lograrlo.La principal conclusión enfatiza que la construcción de la credibilidad del IPM chileno, así como de otros índices oficiales, se logra cuando su ensamblaje de cuantificación consigue, por medio de una adecuada orquestación institucional y procesos de puntualización, posicionar a entes estadísticos no-humanos (reportes y documentos metodológicos, bases de datos, cuestionarios, entre otros) como los responsables de las decisiones metodológicas del índice quitando espacios de discreción a entes humanos. Este resultado permite enriquecer una problemática abordada frecuentemente por trabajos sobre cuantificación y gubernamentalidad: el aparente encubrimiento de las condiciones subjetivas de producción de índices estadísticos bajo un manto de ‘objetividad’.

Published: September 2024

Dhaka is widely recognized as the most polluted city in Bangladesh due to its high levels of particulate matters. Most of the educational buildings in Dhaka South City Corporation are situated alongside the main road. The objective of this study is twofold. First and foremostly, it aims to identify the status of air pollution within educational institutions located in the Dhaka South City Corporation. Secondly, it seeks to assess the relationships among different zones and different air quality parameters, specifically focusing on particulate matter levels of PM₂.₅ and PM₁₀. This study was conducted in 37 locations of Dhaka metropolitan, by using Aeroqual s500. This research study is found that the average concentrations of PM₂.₅ and PM₁₀ in all the selected places of the study area were 68.82 and 113.95 µg/m³ respectively.

Seaweeds are macroalgae growing under marine ecosystems and it plays diversified roles in human life. Different types of seaweeds are available and among them, the widely used ones for extraction are brown seaweeds. One of the significant plants bio-stimulants with a wide range of applications in horticulture and agriculture is seaweed extract (SE). Various methods are employed for their extraction process. The bioactive composition of SE varies according to the type or species of seaweeds and methods of extraction. It has got almost similar effects as that of phytohormones. Seaweed extract application alone or in combination with other bio-stimulants or nutrients during different crop stages are being practised in a broad group of fruit crops (temperate, sub-tropical and tropical fruit crops).  An array of research studies has also revealed that the usage of seaweed extracts is more environmentally friendly owing to their organic nature and cost-effectiveness. It has proven significant improvements on growth, yield, quality, storage and stress tolerance. Hence, the use of seaweed extract at the appropriate time and right concentration to a variety of fruit crops can support the industry's overall growth.

The best water vapor information layer (BWIL) of the 6.7 μm water vapor absorption infrared (IR) band for the FengYun‐2E is investigated over the Tibetan Plateau with standard atmospheric profile and European Centre for Medium‐Range Weather Forecasts (ECMWF) operational model analysis data. The sensitivity tests show that surface characteristics over the Tibetan Plateau have a significant influence on the BWIL. To be specific, topographic elevation, colder skin temperature, and lower emissivity tend to lift the altitude of the BWIL, decrease its magnitude, and narrow the half‐width range. The results from statistical analysis indicate that the altitude of the BWIL reaches the highest in summer and the lowest in winter. Meanwhile, the altitude of the BWIL is highly correlated with the water vapor amount above 500 hPa over the Tibetan Plateau and above 300 hPa over the East China Plain, respectively. The diurnal variation in the BWIL is synchronous with the diurnal variation in the surface skin temperature. It can be concluded from the study that surface characteristics over high terrain in dry and cold atmospheres have more significant impacts on the BWIL. With multiple water vapor absorption IR bands, the imagers on board the new generation of geostationary satellites will provide crucial improvement in water vapor remote sensing over the current single water vapor band on board the FY‐2 series according to the analysis in this study.
Unusual Regioselectivity in the Gold(I)‐Catalyzed [3+2] Carbocycloaddition Reaction of Vinyldiazo Compounds and N‐Allenamides
Authors: López Enol , González Javier , López Luis A.
Published: April 2016

The reaction of N‐allenamides with alkenyl diazo compounds in the presence of gold catalysts provided methylidenecyclopentene derivatives resulting from a formal intermolecular [3+2] carbocyclization, a rare process in the gold chemistry of allenes. The participation of the CαCβ bond of the allenamide represents a very unusual regioselectivity in gold‐catalyzed cycloaddition reactions of this type of allenic scaffolds. A stepwise mechanism involving initial activation of the diazo component has been proposed.
