Published: June 2022

Solid-state electrolytes are an attractive option to increase the chemical stability and energy density of rechargeable lithium-metal batteries. However, they are susceptible to lithium-metal short-circuiting during charging, especially under high current densities. In this work, using a force-controlled electrical microprobe inside a focused-ion beam scanning electron microscope, we performed 48 experiments of electroplating lithium metal onto Li6.6La3 Ta0.4Zr1.6O12 (LLZO) and observed the initiation of lithium penetration (termed intrusions) into the solid electrolyte, with and without externally applied stress. Employing a statistical approach, we find that the cumulative probability of intrusion as a function of lithium metal diameter follows a two-parameter Weibull distribution, implying defect-governed fracture behavior for the intrusion initiation. Upon applying a contact force of 5 mN with a 5-10 µm microprobe, the characteristic failure diameter of lithium metal decreases by a factor of 2.6 due to the generation of nanoscale cracks as suggested by nanoindentation and finite element simulations. Furthermore, we introduce in-plane compressive strain to LLZO through a cantilever bending experiment and demonstrate that strain as small as 0.067% strongly influences the direction of intrusion propagation immediately following initiation. Overall, our results suggest that both mechanically-generated and pre-existing defects as well as mechanical strain dominate the intrusion behavior in LLZO, a phenomenon that could extend to other solid electrolytes.

Published: June 2022

Designing highly selective molecules for a drug target protein against off-targets, including pharmacokinetics and toxicity-related proteins, is a challenging task in drug discovery and can be regarded as a multiobjective problem. Recent breakthroughs in artificial intelligence have accelerated the development of molecular structure generation methods, and various researchers have applied them to computational drug designs and successfully proposed promising drug candidates. However, designing efficient selective inhibitors with releasing activities against various homologs of a target protein remains a difficult issue. In this study, we developed a de novo structure generator based on reinforcement learning that is capable of simultaneously optimizing multiobjective problems. Our structure generator successfully proposed selective inhibitors for 9 tyrosine-kinases while optimizing 9 other objectives related to pharmacokinetics and drug-likeness properties. These results show that our structure generator and optimization strategy for selective inhibitors will contribute to the further development of practical structure generators for drug designs.

Published: June 2022

We designed and synthesized two new ionic thermally activated delayed fluorescent (TADF) emitters that are charged analogues of a known multiresonant TADF (MR-TADF) compound, DiKTa. The emission of the charged derivatives is red-shifted compared to the parent com-pound. For instance, DiKTa-OBuIm emits in the green (λPL = 499 nm, 1 wt% in mCP) while DiKTa-DPA-OBuIm emits in the red (λPL = 577 nm, 1 wt% in mCP). In 1 wt% mCP films, both emitters showed good photoluminescence quantum yields of 71% and 61%, and delayed life-times of 316.6 μs and 241.7 μs, respectively, for DiKTa-OBuIm and DiKTa-DPA-OBuIm, leading to reverse intersystem crossing rates of 2.85 × 103 s-1 and 3.04 × 103 s-1. Light-emitting electrochemical cells were prepared using both DiKTa-OBuIm and DiKTa-DPA-OBuIm as ac-tive emitters showing green (λmax = 534 nm) and red (λmax = 656 nm) emission, respectively.
Ion Binding Site Structure and the Role of Water in Alkali Earth EDTA Complexes
Authors: Foreman Madison , WEBER J. Mathias
Published: June 2022

The interactions between molecular hosts and ionic guests and how the chemical environment in aqueous solutions changes these interactions are challenging to disentangle from solution data alone. The vibrational spectra of cold complexes of ethylenediaminetetraacetic acid (EDTA) chelating alkaline earth dications in vacuo encode structural characteristics of these complexes and their dependence on the size of the bound ion. The correlation between metal binding geometry and the relative intensities of vibrational bands of the carboxylate groups forming the binding pocket allows us to characterize changes in molecular geometry by interaction with other molecules. The evolution of these structural markers from bare ions to water adducts to aqueous solution illustrates the role of water for the structure of ion binding sites in chelators. The results show that the binding pocket of EDTA opens up in aqueous solution, bringing the bound ion closer to the mouth of the binding site, and leading to an increased exposure of the bound ion to the chemical environment.
Revisiting the Orbital Energy Dependent Regularization of Orbital Optimized Second Order Møller-Plesset Theory
Authors: Rettig Adam , Shee James , Lee Joonho , Head-Gordon Martin
Published: June 2022

Optimizing orbitals in the presence of electron correlation, as in orbital optimized second-order M{\o}ller-Plesset perturbation theory (OOMP2), can remove artifacts associated with mean-field orbitals such as spin contamination and artificial symmetry-breaking. However, OOMP2 is known to suffer from divergent correlation energies in regimes of small orbital energy gaps. To address this issue, several approaches to amplitude regularization have been explored, with those featuring energy-gap dependent regularizers appearing to be most transferable and physically justifiable. For instance, $\kappa$-OOMP2 was shown to address the energy divergence issue in, e.g., bond-breaking processes while offering a significant improvement in accuracy for the W4-11 thermochemistry dataset, and a parameter of $\kappa$=1.45 was recommended. A more recent investigation of regularized MP2 with Hartree-Fock orbitals revealed that stronger regularization (i.e. smaller values of $\kappa$) than what had previously been recommended for $\kappa$-OOMP2 may offer huge improvements in certain cases such as noncovalent interactions while retaining a high level of accuracy for main-group thermochemistry datasets. In this study we investigate the transferability of those findings to $\kappa$-OOMP2 and assess the implications of stronger regularization on the ability of $\kappa$-OOMP2 to diagnose strong static correlation. We found similar results using $\kappa$-OOMP2 for several main-group thermochemistry, barrier height, and noncovalent interaction datasets including both closed shell and open shell species. However, stronger regularization yielded substantially higher accuracy for open-shell transition metal thermochemistry, and is necessary to provide qualitatively correct spin symmetry breaking behavior for several large and electrochemically-relevant transition metal systems. We therefore find a single $\kappa$ value insufficient to treat all systems using $\kappa$-OOMP2.
Copper-based 2D Conductive Metal Organic Framework Thin Films for Ultrasensitive Detection of Perfluoroalkyls in Drinking Water
Authors: Gumyusenge Aristide , Quill Tyler , Chen Gan , Gong Huaxin , Bao Zhenan , Salleo Alberto
Published: June 2022

Perfluoroalkyls (PFAS) continue to emerge as a global health threat making their effective detection and capture extremely important. Though metal organic frameworks (MOF) have stood out as a promising class of porous materials for sensing PFAS, detection limits remain insufficient and fundamental understanding of detection mechanisms warrant further investigation. Here we show the use of a 2D conductive MOF film based on copper hexahydroxy triphenylene (Cu-HHTP) to fabricate a chemiresistive sensing device for detecting PFAS in drinking water. We further show ultrasensitive detection using electrochemical impedance spectroscopy. Owing to excellent electrostatic attractions and electrochemical interactions between the copper-based MOF and PFAS, the MOF-based sensor reported herein exhibits unprecedented affinity and sensitivity towards perfluorinated acids at concentrations as low as of 0.002 ng/L.

Designing a Reverse Logistics Network Model for Waste Batteries
Authors: Wang Bin , Hao Hao , Li Hehuang
Published: June 2022

The logistics industry plays an important role in circular economy. Therefore, not only economic benefits, but also environmental protection factors have to be considered in reverse logistics. This paper uses the multi-objective 0-1 mixed integer programming to establish a reverse logistics network optimization model for waste batteries. The objective function is to minimize both, logistics costs and carbon dioxide emissions. The model considers the basic settings of reverse logistics (including recycling nodes, manufacturing, and processing nodes) and the material flow between different settings. In solving the model, Lingo 14.0 is used in this paper. An actual case of a waste battery reverse logistics enterprise verifies the effectiveness of the model in this paper. The results show that the application of this model can effectively improve the operating efficiency of waste battery reverse logistics enterprises.

Authors: Chen Ziyun
Published: June 2022

The official release of China’s new accounting standards has realized the convergence of its accounting standards and international accounting practices. However, affected by factors such as the economic environment, political environment, social culture, law, and tax system, there are still some differences between China’s accounting standards and international accounting standards, which will have a certain impact on the realization of the integration of accounting standards. Therefore, this paper analyzes the environmental factors of accounting differences between China and foreign countries, as well as explores specific measures to reduce the accounting differences between China and foreign countries, aiming to provide some useful references and promote the internationalization of China’s accounting standards.
Analysis of Policy Change in the Implementation Process
Authors: Pan Ziyi , Zhang Ke
Published: June 2022

Policy implementation, refers to putting policy intentions into effect. This process largely depends on the interactions between the implementers and their service users, partners, and superiors. The reasons for policy change can be attributed to three aspects. Firstly, varied contextual conditions require changing policy measures adapted to different situations, and vague policy goals that permeate the policy process provide the prerequisite for policy deformation. Secondly, policy delivery agencies, who lack resources and supervision, “decode” policy goals based on practical contexts and arrange the tasks. Thirdly, street-level bureaucrats use discretion based on working attributes and personal factors. Finally, these factors from multiple layers interact and result in policy changes in the implementation process. This article illustrates the macro-level implementation environment and the meso-level implementation institutions, which compose the prerequisite conditions for policy implementation, as well as micro-level implementers, who play key roles in shaping policies. This comprehensive analytical structure is helpful to determine the effectiveness of public policies.
Why People Don’t Want to Enter Big Cities? Professional Ties and Small-Town Living Based on The Case of Village in Central China
Authors: Song Yuan
Published: June 2022

Based on the experience of peasants in Li Village in the Central China, the urbanization process of Chinese farmers does not always continue to develop towards the big cities. Farmers’ willingness to enter big cities is influenced by their professional ties. This study found that, the simple social division of labor in a small-town lead to an infertile development of interpersonal trust. With low-end occupations and high homogeneity, people could not organize their relationships by professional logic. Based on the lack of relationship and trust, social support is insufficient, as a consequence, people start to shrink their social interaction thereby their developmental needs are further inhibited.
Design with Geo-Hazards: An Integrated Approach from Engineering Geological Methods
Authors: Vallejo Luis I. G.
Published: June 2022

An engineering geological approach to analysed geo-hazards affecting engineering and planning design decisions is presented. The methodological procedures include hazard identification, hazard assessment, site vulnerability, economic cost, environmental impact, risk assessment, social acceptability, decision analysis and engineering design criteria. The practical application of the Engineering Geological Methodology (EGM) is shown in several case studies: dam safety problems due to slope instability and induced seismicity during reservoir filling; seismic hazard assessment in regions with insufficient seismic data and tectonic information; and large scale geo-hazards due to giant landslides and related tsunamis. The EGM approach can provide fundamental criteria for engineering decisions and territorial planning. Social acceptability should be included in the decision analysis being evaluated according with the hazard level of the geological process and the corresponding risk of the affected elements. Examples of geo-hazards and their social acceptability are presented.

Published: June 2022

. This paper presents a system for performing down-hole seismic test together with the piezocone test in order to determine the shear wave velocity (Vs) and for calculating the maximum shear modulus (Go); a basic parameter for analyzing the dynamic soil behavior and a reference value of the soil stiffness. The system components are described and tests results for checking the geophone response are also presented, both before and after installation into the probe. The system was used in down-hole tests carried out at three experimental research sites located in the interior of Sao Paulo State, Brazil, where in situ seismic test results are available. The Vs values measured in down-hole tests carried out with this system were consistent with those determined in cross-hole tests and with a commercial seismic piezocone, which enabled to validate the developed system.
In-Situ Tests and Numerical Simulation about the Effect of Annulus Thickness on the Resin Mixture for Fully Grouted Resin Bolt
Authors: Zingano Andre , Peng Syd , Koppe Jair , Costa João F.
Published: June 2022

The main purpose of this paper is to study the effect of annulus thickness on the quality of resin mixture for fully grouted resin bolt. Pullout and mixture tests were made in underground coal mines for the following arrangements: (a) 29 mm borehole diameter, and 19 mm roof bolt diameter with steel wire around the roof bolt; (b) 29 mm borehole diameter, and 19 mm roof bolt diameter with no wire around the roof bolt; and (c) 24 mm borehole diameter, and 19 mm roof bolt diameter with no wire around the roof bolt. The mixture test in steel pipe showed that the best resin mixture is for the 24 mm borehole diameter. The arrangement (b) produced big voids around the bolt. But for the 24 mm hole, arrangement (c), the mixture showed the best results. This was corroborated with the pullout tests results where there was a difference in grout stiffness: in the 24 mm borehole diameter is was about 10 times higher than in the 29 mm borehole diameter. On the other hand, as far as the cohesive strength is concerned, the difference is not significant. Numerical models were built to simulate the pullout tests, and also to simulate the roof support at an intersection. Convergence at two underground intersections, consisting of an immediate roof with laminated sandstone, was monitored to evaluate the performance of the roof supports, using the 29 and 24 mm diameter boreholes (i.e. arrangements ‘a’ and ‘b’). The readings showed that the 24 mm borehole diameter resulted in a slightly smaller convergence.
Simulation of the Mechanical Behavior of Fiber Reinforced Sand using the Discrete Element Method
Authors: Velloso Raquel Q. , Casagrande Michéle D.T. , Junior Eurípedes A.V. , Consoli Nilo C.
Published: June 2022

The general characteristics of granular soils reinforced with fibres have been reported in previous studies and have shown that fibre inclusion provides an increase in material strength and ductility and that the composite behaviour is governed by fibre content, as well as the mechanical and geometrical properties of the fibre. The present work presents a numerical procedure to incorporate fiber elements into an existing discrete element code (GeoDEM). The fiber elements are represented by linear elastic-plastic segments that connect two neighbor contacts where the fiber is located. These elements are characterized by an axial stiffness, tensile strength and length. The effect of the addition of fibers was evaluated numerically by comparing the stress-strain behavior of a pure sand with and without fibers. These simulations showed that the addition of fibers provides a significant increase in strength for the mixture in comparison with strength of the pure sand.

Published: June 2022

The literature review of previous studies and the analysis of observations and knowledge gathered in Africa, as well as regional experience in Brazil, India and Australia on the influences of texture, grain size distribution and mineralogy conditions on the stability of materials used in pavement base have shown that the mechanical behaviour of lateritic soils is strongly influenced by their physical and mineralogical properties, we argue in this article that development of new procedures for classification of these soils as new building materials, that consider appropriate designs for the humid tropics and the nature and state parameters associated with the mechanical behaviour, can broaden the use of a higher percentage of local soils in pavement layers for low cost road compared to traditional techniques.
Tunnel Face Reinforcement by Bolting - Numerical Modelling of Centrifuge Tests
Authors: Janin Jean P. , Dias Daniel
Published: June 2022

This paper presents the results of numerical investigations on the deformation behaviour of a tunnel face reinforced by longitudinal pipes. The three dimensional finite difference calculations are based on series of reduced-scale centrifuge model tests (Al Hallak, 1999). Numerical analyses are developed and carried out with particular emphasis on the validation of the excavation method. Geomechanical parameters of two constitutive models are calibrated on triaxial and oedometric tests. The numerical models are then compared with the centrifuge model results. This comparison concerns especially the tunnel face extrusion, the ground surface settlements and the minimum pressure that guarantees the face equilibrium before failure. Bolting influence on these parameters is studied.

Published: June 2022

The article is devoted to the construction of methodology for the study of performance as an art form. The desired methodology is based on the comparison, analysis and ontologization of knowledge about performance as an art form. Based on the obtained ontology of performance as an art form, methodological tools are developed to provide the feasibility of the functional study of performance as an art form. The resulting methodology is expressed as an algorithmic model for the study of performance as an art form. The article describes the model, its components and the relationships between them. The received construction can be used as a tool for the analysis of artworks, the study of performance within the disciplinary framework of art history, and the study of certain aspects of performance as an art form. The structure of the model involves making changes and additions either in the process of further research or as a result of the discovery of new components and relations between them. Therewith, this methodology allows the study of performance as an art form without the use of empirical material and variable knowledge representations of the subject.

Osmanlı-Hırvat ilişkileri, XV. yüzyılın sonlarına doğru başlamış; Kanunî Sultan Süleyman’ın Orta Avrupa içlerine ilerlediği yıllarda bugünkü Hırvatistan topraklarının büyük kısmı fethedilmiştir. Fethedilen bu topraklar, II. Viyana Kuşatmasından sonra ve 1699 Karlofça Antlaşmasıyla Venedik Devleti’ne bırakılmıştır. Böylelikle Türkler bugünkü Hırvatistan topraklarından çekilmiştir. Hırvatistan’da XVI. yüzyılda başlayan ve XIV. yüzyılda biten Osmanlı hâkimiyeti, Hırvatları siyasi, askerî, kültürel ve edebiyat gibi alanlarda etkilemiştir. Bu etkinin görüldüğü eserlerden biri de ünlü Hırvat yazar ve siyasetçi İvan Mažuranić’in yazdığı İsmail Çengiç Ağa’nın Ölümü (Smrt Smail-Age Čengića) adlı eserdir.

Authors: Smuts Stefan , Smuts Hanlie
Published: June 2022

Society 5.0, with all its different cyber-physical aspects not only presents a technical challenge, but also significantly changes the structures and business processes of organizations. It requires software engineers and developers to consider a new level of socio-technical interaction and planning. Software should not be the point of friction among products, services and users, but should rather encourage software engineers and developers to become more human-oriented. Therefore, the purpose of this study was to investigate the future of work skills in Society 5.0 for software engineers and developers. We collected and analyzed two datasets; one dataset containing academic peer reviewed publications and the second dataset encompassed popular press articles that predicted the future of software engineering and development. We used the Software Engineering Body of Knowledge (SWEBOK) to map the data and found that future of work skills for software engineers and developers are driven by software foundations and the evolution of new programming languages and technologies e.g. quantum computing. In addition, software professional practices such as containerization, no / low-code development and fast innovation / prototyping cycles will affect the future of work together with software development practices such as cross-platform development, continuous integration and deployment, and cybersecurity. Based on the findings, we developed a skills evaluation tool that could be used to establish a future of work skills profile. By considering the evolution of the software engineering and –development role, as well as the future requirement due to technology evolution, a software engineer and developer may be able to prepare themselves for the Society 5.0 domain.
MediHopps: A novel approach to virtual rehabilitation sport
Authors: Gottschalk Tobias , Gisa Kevin , Dahlem Nanna , Reichl Lea , Greff Tobias , Werth Dirk
Published: June 2022

Throughout Germany, there is an increasing demand for home-based rehabilitation sports, especially in rural areas. Although current systems already target location- independent remote sports, the practice of training is not possible in groups. Especially the aspect of collaborative rehabilitation sport is demonstrably decisive to strengthen the self-help character of the performance and to achieve positive group dynamic effects. Extended Reality represents a promising technology to provide location-independent effective group rehabilitation sports training. Therefore, the research project MediHopps aims to develop an intelligent full-body holoporation for stand-alone XR glasses, which makes it possible to precisely capture body postures and poses and transfer them to digital avatars in the virtual world just by wearing multisensory glasses. The purpose is to enable collaborative medically precise telerehabilitation in a virtual training room. The intelligent assistance system classifies the recognized movements and detects incorrectly performed exercises. MediHopps thus creates an easily accessible, supervised, qualitatively controlled and location-independent rehabilitation sports training including positive group dynamic effects. The research project solves thereby social challenges referring to limited access possibilities for rehabilitation sport and contributes to a human-centered Society 5.0.
Productivity Enhancements through Fourth Industrial Revolution Technologies: Comparison of Small- and Medium-Sized Enterprises with Large Enterprises
Authors: Backhaus Simon Karl Hubert , Nadarajah Devika
Published: June 2022

The purpose of this paper is to compare small- and medium-sized enterprises (SMEs) against large

enterprises (LEs) in terms of their productivity enhancements through Fourth Industrial Revolution

(IR4) technologies, specifically in the context of developing countries.

This study adopted a quantitative approach. Questionnaires were distributed to Malaysian manufacturers registered under Malaysia External Trade Development Corporation MATRADE via email and in-person at the Smart Manufacturing Uprising conference in Kuala Lumpur. A total of 76

valid responses were obtained and analyzed using multiple regression.

SMEs’ productivity was found to have significantly increased due to the Internet of Things and digital automation without sensors, while LEs’ productivity revealed a significant improvement from

integrated engineering systems.

The small sample size of 76 raises generalizability issues. Thus, large-scale quantitative research is

recommended to validate the relationships identified in this study.

The study is among the first to identify and compare the significant relationships between IR4

technologies and productivity enhancements among SMEs and LEs. The findings are of interest to academics as well as to public and private sector practitioners in directing resources to technologies

that enhance productivity.
Key user experience principles in designing computer interfaces for emotionally vulnerable user groups
Authors: du Preez Solett , Coleman Kalley , Smuts Hanlie
Published: June 2022

The highly integrated Society 5.0 enables a ubiquitous computing world driven by exponential growth of digital technologies. User interface designers must therefore find new architectures and -designs in order to compete in a digital world. User experience (UX) design is the overarching term that expresses the philosophies, approaches, tools and techniques related to the two distinct yet overlapping fields of human-computer interaction (HCI) and user-centered design (UCD). In order to create reliable and realistic representations of key audience segments, personas are used as a mechanism to simulate the engagement with the computer interface. Personas for distressed and vulnerable users take cognizance of a user’s emotional state and potentially unique interaction with the computer interface. The purpose of this study is to consider the key UX principles in designing computer interfaces for vulnerable user groups. Two datasets, consisting of a systematic review of the literature and eye-tracking data, were collected and analyzed. We established 5 key UX principles relevant to vulnerable users entailing simplicity, support, action, engagement, look and feel, and constraint. By applying the key UX principles for vulnerable user groups, designers can ensure that a potentially emotional experience is managed well via the computer interface.

مرّ النحو العربي بعدّة منحنيات وتحديات وأنماط؛ حتى بلغ مرحلة التقعيد والكمال الوضوح في دراسته مع بداية القرن الرابع الهجري. وقد حاول البروفيسور أوينز دراسة التفكير النحوي العربي في مرحلة مبكرة، متشاكسة أو غير مستقرة من تاريخ النحو العربي قبل أن تهمين عليه مدرستا البصرة والكوفة. وتكمن أهمية هذا البحث في الكشف العلمي والتتبع الدقيق لهذه الفترة الزمنية المبكرة، مما كشف أنها كانت فترة تحمل عدم تجانس لغوي؛ حيث كان النحْويون متحررين نسبيًا في مزج الأفكار والمصطلحات من مصادر مختلفة، ثم مهدت هذه الفترة الزمنية الطريق إلى فترة شهدت تجانسًا واتحادًا أكبر، فبلغت ذروتها في كتاب ابن السراج "الأصول في النحو"، الذي استطاع خلال هذا العمل تقعيد النحو العربي بشكل فعال، مما يدعم الرأي القائل إن المدارس اللغوية كالبصرة والكوفة لم تكن موجودة في الفترة المبكرة، وإن فكرة ظهورها ككيان علمي كامل مستقل في أواخر القرن الثالث الهجري كان انعكاسًا لهذا التقعيد؛ لمعرفة تنوع الأفكار والمصطلحات والمعايير التي شهدتها الفترة المبكرة، ولم يتضمنها هذا التقعيد كما كان عند مدرسة الكوفة.
Study Of Evaluation Of Drainage Waterways System In Catchment Area Kertomenanggal Kota Surabaya
Authors: Wahyudi Wahyudi , Prawito Adi
Published: June 2022

Kertomenanggal secondary channel is a channel that passes from the upstream of the Pagesangan Timur 1 channel to the downstream of the Surabaya-Sidoarjo Border Channel Primary Channel along 2.68 km, has a catchment area of ​​1.3 km2. In the rainy season, inundation often occurs at STA 1,455 to STA 1,819 in the Kertomenanggal Channel. This can cause disruption of population activities. Inundation can occur due to flood discharge that is too high, so that the channel capacity is unable to accommodate the existing flood discharge. There are 4 tertiary channels leading to the Kertomenanggal Channel that need to be analyzed, namely, the Menanggal Indah channel, Wisma Menanggal 7, Cipta Menanggal 2, and Wisma Menanggal 1.The method used to find the capacity of the drainage channel includes hydrological analysis used to find the maximum daily average rainfall in the area and catchment area of ​​the Kertomenanggal channel, as well as analysis of channel calculations using the rational method to determine the existing discharge and the planned Kertomenanggal channel.The existing Kertomenanggal channel drainage is 9.530 m3/second, while the incoming design discharge is 11.252 m3/second. The existing size of the Kertomenanggal Channel which is now unable to accommodate the water discharge when it rains, so it is necessary to normalize the channel and change the dimensions of the overflowing channel. Pump optimization needs to be done in order to cope with the planned flood discharge which is greater than the existing discharge of the Kertomenanggal Channel.

Sektor kelautan dan perikanan di Indonesia khususnya Provinsi Lampung memiliki potensi perikanan yang cukup tinggi, yaitu sebesar 387.000 ton/tahun. Akan tetapi, tingkat pemanfaatan perikanan tangkap di Provinsi Lampung berdasarkan Laporan Statistik Perikanan Tangkap, Dinas Kelautan dan Perikanan Provinsi Lampung pada tahun 2014 baru mencapai 157.969 ton/tahun. Angka pemanfaatan tersebut baru mencapai 41,57 % dari total potensi perikanan tangkap provinsi Lampung. Salah satu faktor penting dalam mengembangkan sektor perikanan tangkap adalah dengan mengetahui komoditas dan alat penangkapan ikan (API) unggulan pada daerah tertentu. Penelitian ini dilakukan di Pelabuhan Perikanan Kuala Stabas (PP Kuala Stabas), Provinsi Lampung. Penelitian ini bertujuan untuk menentukan komoditas perikanan unggulan dan jenis alat tangkap yang tepat untuk pemanfaatan  perikanan di PP Kuala Stabas. Metode pengumpulan data yang digunakan ialah dengan wawancara dan responden utama dipilih dengan metode snow-ball sampling. Selain itu, penelitian ini menggunakan metode Comparative Performance Index (CPI) untuk menentukan komoditas perikanan unggulan dan metode analisis skoring untuk menentukan API unggulan. Berdasarkan analisis CPI, komoditas perikanan unggulan di PP Kuala Stabas ialah ikan setuhuk (blue marlin) dengan massa rata-rata ikan sebesar 102,1 kg. Kemudian, hasil kajian terhadap seleksi jenis alat tangkap unggulan dengan metode skoring diperoleh bahwa alat rawai berada pada prioritas utama berdasarkan kajian aspek biologi, jaring gelung berdasarkan kajian aspek teknis, sosial, dan ekonomi, serta jaring rampus berdasarkan kajian aspek ekosistem perairan. Oleh karena itu, dapat disimpulkan bahwa jaring gelung merupakan alat tangkap terbaik yang dapat digunakan dalam pemanfaatan perikananan di PP Kuala Stabas.

This study evaluated the sedative, and anticonvulsant activities of the aqueous (AESM) and ethanol (EESM) dried leaf extracts of Solenostemon monostachyus. The sedative effect of the extracts was evaluated with ketamine-induced hypnosis (100 mg/kg, i.p.). Also, the anticonvulsant activity was evaluated using pentylenetetrazole (PTZ)-induced convulsion (85 mg/kg, i.p.), strychnine-induced convulsion (2 mg/kg, i.p.) and maximal electroshock (MES)-induced convulsion models. The AESM (200 mg/kg, p.o.) gave 66.67% protection, while EESM (800 mg/kg, p.o.) gave 100% protection against the hind limb tonic extension on the MES. The AESM only at 200 mg/kg, p.o. caused a significant change (p < 0.01) in the convulsion latency and time of death in PTZ –induced convulsion. The AESM and EESM (200, 400 and 800 mg/kg, p.o.) significantly (p < 0.05 – 0.01) shortened sleep latency. At 400 and 800 mg/kg, p.o., AESM prolonged (p < 0.05) total sleeping time while EESM at 800 mg/kg, p.o. significantly (p < 0.05) prolonged total sleeping time relative to vehicle. The study concluded that the aqueous leaf and ethanol dried leaf extracts of S. monostachyus possessed sedative and mild anticonvulsant activities.

Stunting is known as length for age below minus two standard deviations (<-2 SD) of the WHO Child Growth Standard nutritional status. Several causes are identified, including exposure to pesticides (rotenone), which works by inhibiting mitochondrial complex I as an ATP-producing site and generate oxidative stress that affects glucose delivery and bone elongation involving GLUT 1 and osteocalcin. Centella asiatica is a high antioxidant herbal plant with anti-inflammatory properties. This study aimed to investigate the effect of Centella asiatica ethanolic extract on the rotenone-induced stunting zebrafish (Danio rerio) larvae model through GLUT 1 and osteocalcin expressions. This study found that 12.5 ppb of rotenone can induce about 6 dpf (day post-fertilization) zebrafish larvae into stunting. The effect of Centella asiatica ethanolic extract on increasing body length in stunting zebrafish larvae works by increasing the expression of GLUT 1 and osteocalcin expressions. The correlation test showed a positive and strong relationship between this ethanolic extract level with GLUT 1 and Osteocalcin expression. Thus, the Centella asiatica ethanolic extract effectively promotes the body length by elevating the expression of GLUT 1 and osteocalcin in stunting zebrafish larvae.

Abstract

Parenting a child can be said to be an attempt by parents to create a personality within the child. With the hope that the inherent personality of the child is the best according to their expectations. Not all parents can take good care of adjusting the conditions and abilities of children. Not a few parents who rather force their will where it is not in line with the expectations of the child. And vice versa, it is not uncommon for us to meet parents who care for their children by not giving restrictions or controlling the child's will naturally. To understand more about how appropriate care is implemented for their children and the impacts that occur, this article will explain the understanding, forms of care, and their effects on children.

New materials for smart envelope
Authors: Buanne Mariangela
Published: June 2022

Research on building envelope highlights an important change about the concept of building closing: has lost its historical role as a defensive barrier against environmental impacts and has more and more taken on a role as dynamic interface, characterized by an increasingly enhanced performance. In fact, as a consequence of European and National regulations on the energy performances of buildings, many manufactures of building materials have directed their research to the development of highly energy-efficient components and systems. Building envelope is now a superposition of different specialized layers.
