Di Gampingan terdapat suatu spot panjat tebing yang unik dan sangat menarik untuk dijadikan destinasi wisata alam yang cocok untuk dikunjungi yaitu “Lembah Kera”. Selain “Lembah Kera” juga terdapat tempat wisata lainnya di desa Gampingan yang menawarkan aneka masakan ikan air tawar segar yaitu Mahonian. Tetapi tempat destinasi wisata di desa Gampingan tersebut masih awam didengar oleh masyarakat atau wisatawan di luar Malang dan sekitarnya. Karena problem tersebut maka perlu dibuat suatu media promosi secara elektronik yang bisa menjangkau masyarakat lebih luas agar destinasi wisata desa Gampingan bisa terkenal dan makin banyak pengunjung yang mengunjungi tempat wisata di desa Gampingan. Media promosi yang lagi berkembang sekarang ini adalah melalui media social (facebook, twitter, instagram dan whatsapp) tetapi selain menggunakan social media seharusnya desa harus memiliki portal sendiri yang berisi informasi tentang wisata desa tersebut. Oleh karena itu perlu di generate sebuah website desa yang nama domain sudah mengikuti peraturan kominfo tentang penataan nama domain instansi penyelenggara negara, yang mengharuskan desa memiliki domain website sendiri yaitu desa.id. Dengan domain desa.id diharapkan agar nama domain lebih mudah diakses oleh publik dengan lebih singkat dan jelas. Selain itu juga menjadi bukti nyata, bahwa desa dapat maju, mandiri, dan unggul.

Los centros de mecanizado demandan un alto consumo de energía afectando los costos de producción en las empresas que los emplean. Diferentes estudios relacionan múltiples factores de los centros de mecanizado con el consumo de energía, pero hasta el momento no se identifica con claridad cuáles variables o factores tienen una mayor incidencia en el consumo de energía sin disminuir la calidad del acabado superficial de las piezas fabricadas. En el presente estudio se realizó un análisis descriptivo de la influencia que tiene la profundidad de corte, la velocidad de avance y la velocidad del husillo sobre el consumo de energía y la rugosidad en los centros de mecanizado Haas UMC-750 y el centro Leadwell V-40iT®. Se desarrolló una experimentación con un diseño factorial tomando como factores fijos el material base, la herramienta de corte y la ruta de mecanizado. A partir de un análisis descriptivo de los resultados obtenidos en este experimento se logró identificar que la velocidad de avance es el factor que más relación tiene con el consumo de energía. Además, se evidenció la interacción entre los factores identificando que la profundidad de corte posee una influencia moderada sobre la rugosidad o acabado superficial de las piezas. El consumo de energía varía para cada centro de mecanizado y el diseño experimental desarrollado ayudó a caracterizar la influencia de algunas variables de corte sobre el consumo de energía en cada centro de mecanizado.
Estimación de los límites aceptables de tolerancia del costo en ambientes de incertidumbre utilizando simulación de Monte Carlo
Authors: Jiménez Carabali Víctor Javier
Published: June 2022

Aunque las compañías estandarizan sus procesos para obtener productos estandarizados con costos estandarizados, es necesario establecer en qué momento una variación en el costo con respecto al estándar se considera tolerable y cuando deben ser emprendidas acciones correctivas, preventivas o de mejora. El considerar valores tolerables con respecto a un estándar genera la idea que, en vez de ser un valor definido, un estándar puede ser considerado como un intervalo del valor esperado del costo, por lo que valores de costo que pertenecen al intervalo se consideran toreables mientras que valores fuera de dicho intervalo deben generar medidas de intervención por parte de los tomadores de decisiones. Este artículo presenta una metodología que permite establecer el intervalo de tolerancia del costo para un producto. La metodología utiliza un modelo matricial basado en la lógica del costeo basado en actividades que incorpora la simulación Monte Carlo para representar la variabilidad inherente en cada uno de los procesos. La metodología fue aplicada en un caso de estudio en el sector transporte obteniendo como resultado el rango de valores estándar el cual sirve como base para la toma de decisiones tácticas y operativas dentro de la organización.

Primary vs Secondary: Directionalized Guest Coordination in β-Cyclodextrin Derivatives
Authors: Sun Zhaoxi , Zheng Lei , Wang Kai , Huai Zhe , Liu Zhirong
Published: June 2022

The cyclodextrin (CD) and its derivatives as useful drug carriers and reservoirs are widely used in pharmaceutical and chemical industries. The CD-guest (drug) and more generally host-guest coordinations are often considered prototypical cases that are much simpler than biological systems. As a result, in computational modelling even with dynamics propagation, only a single binding pose is considered. However, due to the asymmetric feature of the CD host, the guest can directionally bind to its primary 6’ or secondary 3’ face. Correct modelling of the primary-secondary equilibrium clearly poses a challenge, and any static or dynamic calculations modelling only a single binding preference would introduce systematic biases of unknown magnitude. In this work, using the β-CD host-guest set in a recent grand challenge, we present a comprehensive analysis of various aspects of fixed-charge modelling of β-CD host-guest complexes. The force field parameters (electrostatics and bonded terms) are evaluated in a detailed way, and the best parameter combination is employed in enhanced sampling simulations that accelerate the translational diffusion of the guest molecule, sample the binding/unbinding events extensively, and thus explore the space of possible binding modes. Finally, the binding affinities and the primary-secondary equilibrium (directionalized guest coordination preference) are computed and compared with the experimental reference. Possible reasons for deviations and further ways to improve the quality of calculation are discussed.

Spatial control over chemical reactions is a ubiquitous feature shared by all living organisms. In the present article, we describe the design of a proteinaceous, synthetic capsid based on the well-described bacterial nanocompartment encapsulin. Our engineered virus-like particle carries a dual functional artificial metalloenzyme (ArM) as non-native guest protein. This ArM, created from a fusion protein of HaloTag and monomeric rhizavidin, serves as catalyst for a fully bioorthogonal, linear, two-step reaction cascade. A ruthenium-catalyzed alloc deprotection is followed by a gold-catalyzed, ring-closing hydroamination reaction leading to indoles and phenanthridines with up to 67 % overall yield in aqueous solutions.
Understanding the capacity fade in polyacrylonitrile binder-based LiNi0.5Mn1.5O4 cells

Published: June 2022

Binders are electrochemically inactive components that have a crucial impact on battery aging although being present in only small amounts, typically 1-3% w/w in commercial products. The electrochemical performance of a battery can be tailored via these inactive materials by optimizing the electrode integrity and surface chemistry. Polyacrylonitrile (PAN) for LiNi0.5Mn1.5O4 (LNMO) half-cells is here investigated as a binder material to enable a stable electrode-electrolyte interface. Despite being previously described in the literature as an oxidatively stable polymer, it is shown that PAN degrades and develops resistive layers within the LNMO cathode. We demonstrate continuous internal resistance increase in LNMO-based cells during battery operation using the intermittent current interruption (ICI) technique. Through a combination of on-line electrochemical mass spectrometry (OEMS) and X-ray photoelectron spectroscopy (XPS) characterization techniques, the degradation products can be identified as solid on the LNMO electrode surface, and no excessive gas formation is seen. The increased resistance and parasitic processes are correlated to side-reactions of the PAN, possibly intramolecular cyclization, which can be identified as the main cause of the comparatively fast capacity fade.

Published: June 2022

17O NMR spectroscopy is a powerful analytical technique, which enables to access unique information regarding the structure and reactivity of biomolecules, such as peptides and proteins. However, due to the exceedingly low natural abundance of 17O (0.04 %), it is necessary to work with 17O-enriched samples, which are not easily accessible because of the experimental constraints and high costs associated with the traditional enrichment procedures. Here, we present simple, fast and cost-efficient labeling strategies for 17O-enrichment of amino acids and peptides. First, using mechanochemical saponification, a variety of unprotected amino acids were enriched within 30 min of milling under ambient conditions, consuming only microliter amounts of costly labeled water, and producing pure molecules with high enrichment levels (up to ~ 40 %), and in medium to high yields (~ 60 - 85 %) without the loss of their optical purity (ee > 99%). The labeling efficiency of the mechanochemical protocol was then compared to a re-optimised enrichment strategy based on acid-catalysed oxygen exchange. Subsequently, 17O-enriched Fmoc/tBu-protected amino acids were produced on a 1 g/day scale with high enrichment levels (~ 40 %), and in high synthetic yields (~ 75 - 85 %), by scaling up the mechanochemical enrichment followed by a Fmoc-protection step. Lastly, a direct site-selective 17O-labeling of carboxylic functions in peptide side-chains was developed and applied to the RGD and GRGDS peptides, reaching up to 29% enrichment level. Producing highly enriched molecules enabled to record 17O solid-state NMR spectra at 14.1 T in reasonable analytical times. Overall, this work represents an important step forward in providing easy access to highly 17O-enriched peptides and proteins to be subsequently studied by high-resolution 17O NMR spectroscopy.

Published: June 2022

The large scale recycling of lithium ion batteries (LIBs) is essential to satisfy global demands for the raw materials required to implement this technology as part of a clean energy strategy. However, despite what is rapidly becoming a critical need, an efficient and sustainable recycling process for LIBs has yet to be developed. Biological reactions occur with great selectivity under mild conditions, offering new avenues for the implementation of more environmentally sustainable processes. Here, we demonstrate a sequential process employing two bacterial species to recover Mn, Co and Ni, from vehicular LIBs through the biosynthesis of metallic nanoparticles, whilst Li remains within the leachate. We investigated bio-selectivity between Co and Ni using proteomics, confirming control of the biological response. Our approach determines the principles and first steps of a practical bio-separation and recovery system, underlining the relevance of harnessing biological specificity for recycling and up-cycling critical materials
Fluorescent ligands targeting the intracellular allosteric binding site of the chemokine receptor CCR2

Published: June 2022

Fluorescently labeled ligands are versatile molecular tools to study G protein-coupled receptors (GPCRs) and can be used for a range of different applications, including bioluminescence resonance energy transfer (BRET) assays. Here, we report the structure-based development of fluorescent ligands targeting the intracellular allosteric binding site (IABS) of the CC chemo-kine receptor 2 (CCR2), a class A GPCR that has been pursued as a drug target in oncology and inflammation. Starting from previously reported intracellular CCR2 antagonists, several tetramethylrhodamine (TAMRA) labeled CCR2 ligands were designed, synthesized and tested for their suitability as fluorescent reporters to probe binding to the IABS of CCR2. By means of these studies, we developed 14 as a fluorescent CCR2 ligand enabling cell-free as well as cellular NanoBRET-based binding studies in a non-isotopic and high-throughput manner. Further, we show that 14 can be used as a tool for fragment-based screening approaches as well. Thus, our small molecule-based fluorescent CCR2 ligand 14 represents a promising tool for future studies of CCR2 pharmacology.
Theoretical and Experimental Investigations of Shape Memory Characteristics of Miscible Rubber-Wax Blends
Authors: Khewle Surbhi , Nemani Priyanka , Sharma Nikhil , Dayal Pratyush
Published: June 2022

Shape Memory Polymers (SMPs) are smart materials capable of transforming back to their intended shape and therefore, are used to replicate biomimetic functionalities in synthetic materials. Here, we demonstrate that polymer blending can be used as an effective technique to design SMPs. In particular, the blends consists of wax and rubber that signify soft and hard segments of the SMP, respectively. In particular, we use the standard linear viscoelastic model where the two constituents, rubber represented by Hookean spring and wax represented by Maxwellian liquid, are connected in parallel; hence, we assume that the contribution of each component in the total stress is distributed in proportion of the composition. Via simulation, we establish that wax and rubber, individually do not exhibit shape memory behavior but do so upon blending; the shape memory behavior is qualitatively validated from experiments. We also confirm that the shape memory properties of our rubber-wax blends, namely, the shape fixity and shape recovery ratios at different concentrations, is in qualitative agreement with the properties of SMPs. Our findings indicate that polymer blending can be seen as an alternative strategy to design SMPs; the properties of these polymers can be varied directly by changing the composition of the blend.
Pandemia y disparidades regionales de salud en el Perú: 1997-2020
Authors: Díaz Maraví Saúl Darío
Published: June 2022

El presente artículo tuvo como objetivo mostrar la causalidad entre las desigualdades regionales y la mortalidad de la pandemia por COVID-19. Esto se debe a la presencia de las disparidades regionales que generó ausencia de políticas para reducir dichas desigualdades regionales. Para ello se analizó el sector salud por regiones en términos de presupuesto, número de médicos, número de enfermeras y número de hospitales. Estas disparidades se reflejan en la mortalidad causada por la pandemia. En la investigación, se utilizó el enfoque de investigación cuantitativa y el método hipotético deductivo, con diseño no experimental ex post facto de retrospectiva simple con datos de fuentes secundarias. Y se encontró que existe una alta significancia estadística entre desigualdades regionales y mortalidad por COVID-19, donde Lima es 17 veces el tamaño promedio de los sistemas de salud del resto de las regiones. Asimismo, se ha encontrado una reducción de la desigualdad presupuestaria medido con el índice de GINI donde de 0.30 en 1997 se pasó a 0.16 en el 2018. Igualmente se aumentó significativamente el presupuesto per cápita por regiones donde en términos promedio creció en un 78% desde 1997 a 2018. Pero, todo esto no ha sido suficiente para afrontar la pandemia con éxito, sino todo lo contrario. En conclusión, el modelo económico no generó una infraestructura adecuada para enfrentar la pandemia de la COVID-19 y existe mucha disparidad en la cobertura de salud entre regiones.
The Concept of “Eschatological War” in the Modern Marginal Prophetic Discourse
Authors:   Herzen State Pedagogical University of Russia, Prilutskii A. M.
Published: June 2022

This article is devoted to the analysis of the significance of the concept of eschatological war for the development of modern prophetic discourse, which is popular in marginal Orthodox communities. Under the discourse of marginal prophetics, the author understands a set of religious texts that set out various prophecies and predictions, often of an anonymous or pseudonymous nature, popular among sectarian Orthodox movements. In the course of the study, the main hermeneutical patterns of explaining the purpose of the eschatological war were revealed. 1 War as a way of physical destruction of a significant part of the population of the Earth. 2 War as a way of the accession of the Antichrist. 3 War as a way to save the elect. 4 War as a condition for the accession of the Russian Orthodox Tsar. All these patterns are analyzed in the article from the point of view of pragmatics and semantics. Further, the article lists the main types of configuration of military relations and makes the assumption that their formation was influenced by the changing geopolitical situation and numerous subjective factors. The main signs of eschatological war are investigated: brevity, worldwide character and special destructiveness.

In research literature this phenomenon is traditionally understood as a reaction to secularization, secularism and modernism. However, as illustrated in this article, today it is rather a response to pluralism and relativism in search of “meanings” and “foundations” of being in the context of worldview uncertainty/ “new boundlessness” (J. Habermas). Due to this background and new tasks modern fundamentalism is substantially transformed. It does no longer emphasize the returning to the “foundations” of religion: sacred texts, theological basis of the doctrine (orthodoxy) or to the religious and civilizational foundations of unity. It desires restoration or a new creation of the “proper”, taken on faith, understanding of the reality after the relativization. Therefore it may not refer only to the religious movements but also to the secular ideologies. This new quality of the modern fundamentalism allows to interpret/understand it metaphorically as the “mania of the foundations”, which is an additional optics and a theoretical and methodological toolkit for studying religious fundamentalism in the context of transformation of religion in general.

The article examines the religious features of the Alawite religion and briefly describes the religious situation in Iran in the 3rd – 9th centuries. By the comparative characteristic of religious and political currents in Iran in the 9th century the author has come to the conclusion that the ancestral home of the Alawites was the land of Caucasian Albania or Arran. The above conclusions are supported by the ethnic factor as the political activity of ethnic groups and the territories they occupy in Iran. In addition, the author considers other factors that confirm the correctness of determining the origin lands of the Alawite tribes.
Eudaimonia: Elaborasi Filosofis Konsep Kebahagiaan Aristoteles dan Yuval Noah Harari

Ever has man sought happiness to enrich his days, to such lengths that twould not be an understatement to state happiness is his life’s goal. Aristotle defines happiness as eudaimonia, a goal which must be achieved by any means, whilst Harari offers the definition as a process of knowing oneself but even so a meeting point between the two I claim may be possible particularly in this day and age in order to seek and achieve hap- piness. As one may derive from the meeting point, both agree happiness is not limited to the simple fulfillment of physical needs. Happiness possesses an internal dimension, wrought once one lives a wholesome existence in concord to ones vocation.

The problem that has yet to find a boundary for resolution in Indonesia is how to reconcile religious pluralism. This paper focuses on the problems of religion which are often destructive, reductive and asymmetrical. Religious hegemony that dominates the public sphere is more aggressive, confrontational and egocentric than altruistic and cooperative. The tendency of religious actors to affirm their own religion better than others has triggered the emergence of various kinds of conflict. The face of religion seems to undermine Pancasila as the spirit and breath of the Indonesian people. Start- ing from this problem, the method used in this paper is the literature method. With this method the author grapples with a wealth of knowledge to restore religious life. So, as the findings of this paper, the writer presents a new paradigm that the Indonesian nation needs to be purified and restored. The Indonesian nation must receive the sacrament of reconciliation and this must become a collective consciousness of the Indonesian people. Reconciliation means being able to open oneself to forgive others and create conducive and harmonious spaces for togetherness.
Adapt: An experimental design for the application of thermo-responsive shape memory polymers into building envelopes
Authors:   , Al Mansori Saba
Published: June 2022

The future of architecture in New Zealand goes hand-in-hand with its ability to adapt to climate change projections. Since the establishment of the modern era, construction materials have remained largely unchanged. Steel, timber, concrete, and brick are all very static in functionality, are the backbone of our built environments. The shifting climate conditions anticipated in the coming decades require adaptable and resilient construction materials. Temperature Rise for New Zealand is 0.3°C to +0.9°C by 2030 and 0.6°C to +2.7°C by 2070, (O’Connell and Hargreaves 1). The expected increase in temperatures around New Zealand homes will negatively affect the internal thermal comfort of occupants.

The development of shape memory polymers (SMPs) as an auto-responsive and functional system that responds to numerous environmental stimuli becomes a viable option for smart material integration into external building envelopes. The useful properties of SMPs as a lightweight material with reversible shape-changing capabilities, and deformation mechanisms are becoming increasingly realistic for practical implementation into building facades (Mohamed).

The implementation of thermo-responsive shape memory polymers into residential building facades allows for a real-time automated response to manage climatic temperature variances for present and future vulnerabilities of buildings and their occupants. Reinventing building envelopes using shape memory polymer application has the potential to create efficient passive cooling methods which may satisfy the demand for architectural climatisation and improve indoor thermal comfort for occupants. Establishing a proof-of-concept for adaptable and resilient design needs to be fast-tracked into New Zealand’s mainstream construction, showcasing smart materials' necessity and innovative capabilities. The reactionary approach to construction is not a viable option for future climate change projection. The damage to buildings without immediate implementation of climate-adaptive design will be irreversible and detrimental for thousands of New Zealanders. The future of building materials within the construction industry must endeavour to steer away from traditional building materials into the inevitable smart material technology.
How to Be a Reflective Teacher?
Authors: Wu Yuting
Published: June 2022

Since the 1980s, educational experts and scholars from western countries have carried out multi-level and multi-angle research on “reflection,” “reflective teaching,” “reflective teacher,” and other subject matters, and fruitful results have been achieved [1]. Since the late 1990s, the research on reflective teachers in China has gradually deepened. Not only a considerable number of papers have been published, but also numerous monographs. This paper defines the term “reflective teacher,” explores and studies the nurturing of reflective teachers, clarifies the relationship between reflection and classroom, and highlights the characteristics that reflective teachers should have.
RESOURCE-SAVING ENERGY-EFFICIENT GRAIN CORN PRODUCTION TECHNOLOGY

To assess the effectiveness of corn cultivation technology based on the minimum tillage technology (Mini-till) and organic fertilizers, and compare it with the conventional technology including mouldboard ploughing, the authors conducted field studies in two farms of the Novokubansk district of the Krasnodar region. They analyzed economic efficiency indicators of seeders, the machine-tractor fleet, and the technology applied as a whole. The comparative analysis of economic indicators of an Optima TFmaxi direct seeder coupled with a John Deere 8310RT tractor used in the Mini-till technology and seeders used in the conventional technology have shown that using a direct seeder for seeding corn reduces mechanized work input by 0.15 man-h/ha (43%) and fuel consumption by 0.2 kg/ha (7%) as contrasted to the conventional one. However, specific operating costs are 3 times higher. The comparative analysis of the use of machinery and tractors in both technologies has shown that the Mini-till technology, as compared with the conventional one, uses less machinery (by 18 units, or 62%). But at the same time, the Mini-till technology uses 100% imported machinery, while the conventional one – only 24%. It has been established that the cost of resources for soil tillage in the Mini-till technology decreased as compared to the conventional one: mechanized work input – by 0.58 man-h/ha (46%), fuel consumption – by 9.1 kg/ha (18%), and specific operating costs – by 1227 rub./ha (17%). While using the Mini-till technology, the farmers recorded a grain corn yield of 10 t/ha, which is higher than that gathered with the conventional technology by 3 t/ha (43%). The obtained scientific and practical results prove the use of the Mini-till technology for economically sustainable agricultural enterprises of all ownership forms in the Southern Federal District of Russia.
Selecting the best general circulation model and historical period to determine the effects of climate change on precipitation
Authors: Yaghoobzadeh Mostafa

Assessing the effects of climate change is a key component of the sustainable management of water resources and food security. In this paper, general circulation models (GCM) were evaluated using historical information for Birjand synoptic station, Iran. Modeling was performed using 35 models of the Fifth Climate Change Report for 27 historical periods. The results showed that longer annual periods are the most suitable periods for hydrological simulation when data are available. Therefore, the periods of 1960-1990 may be the most appropriate periods due to the adaptation to the observation data. To estimate rainfall, periods with more years showed a more accurate forecast of the future. Moreover, the results showed more changes in the RCP 8.5 scenario than in the RCP 4.5 scenario. According to the comparison of models, the NorESM1-M model with a root mean square error (RMSE) of 0.091 and the GISS-E2-R model with a low percent bias (PBIAS) can be an appropriate model for estimating rainfall.
