Published: July 2023

Dusun Sungapan Desa Sadu Kecamatan Soreang Kabupaten Bandung tiap tahunnya mengalami bencana tanah longsor. Penelitian ini bertujuan untuk mengkaji fenomena pergerakan tanah yang terjadi di Desa Sadu dengan mengurangi risiko bencana melalui manajemen bencana yang tepat terkait tanah longsor. Penelitian yang dilakukan ini menggunakan metode penelitian dengan jenis deskriptif kuantitatif melalui pengumpulan data baik data primer serta data sekunder. Adapun teknik pengumpulan data berupa observasi, dokumentasi, wawancara dan studi pustaka. Hasil penelitian menunjukkan bahwasanya potensi bencana tanah longsor di Desa Sadu, Kecamatan Soreang, Kabupaten Bandung dipengaruhi oleh alam dan manusia yang saling berhubungan. Faktor alam diakibatkan oleh intensitas hujan yang mencapai 70-100 mm/ hari, dengan kemiringan lereng berkisar 21-55%. Tanah di Desa Sadu termasuk ke dalam tekstur tanah lempung pasiran yang bersifat asam sehingga sulit meloloskan air dan tanah akan terbebani dan dengan sifatnya yang masam tidak banyak jenis vegetasi yang bisa tumbuh di atasnya. Selain itu, manusia juga menjadi faktor yang menjadi penyebab terjadinya bencana tanah longsor karena masyarakat melakukan alih fungsi lahan menjadi tambang. Oleh karennya, dibutuhkan suatu penanganan tanggap darurat untuk mengatasi persoalan tersebut dengan melakukan manajemen bencana seperti mitigasi struktural dan mitigasi non-struktural yang bertujuan untuk mengurangi risiko terhadap bencana.

The knowledge about nanoaerosols, their potential health effects, their measurement, limitation and administrative-legal treatment has been developed in the last 3 decades in connection with the exhaust gas cleaning of the combustion engines. Nanofiltration, which has thus become known, almost completely eliminates nanoparticles with filters of high durability, high specific filtration areas, and reasonable costs. On the occasion of the Covid pandemic, NanoCleanAir experimentally proved that the viruses in an automotive filter substrate are separated as well as the combustion particles and are also deactivated. To minimize cross exchange of infectious aerosol, new attention must be paid to flow management in ventilated spaces. Digitized flow analysis has also received significant inspiration from engine technology in the past. This paper provides information on some basic investigations and gives valuable advice based on the experimental and numerical results of a retrofitted classroom.

Protected areas are a mainstay of biodiversity conservation. All over the world, plant biodiversity is at risk and every year the number of threatened species increases dramatically. Many of these species are endemic. Sorkhabad Protected Area is situated in Zanjan Province, NW Iran, and is located in the Irano-Anatolian global biodiversity hotspot. The aim of this study is to investigate endemic and threatened vascular plant species, classify the local rarity of these species and identify hotspots of them in this area. 81 endemic species belonging to 59 genera within 22 families and 116 threatened species belonging to 86 genera within 46 families were collected from the area. Fabaceae with 16 and Asteraceae with 14 endemic species are the two largest families and Astragalus L. with 13 endemic species is the largest genus in terms of the number of endemic species. The degree of endemism in the Sorkhabad Protected Area is 15.2 percent. The distribution map of species was prepared using ArcGIS 10.3. The hotspots in terms of endemic and threatened species richness were identified, occupying all told 50,709 ha (41.35%) of the Sorkhabad Protected Area. Identifying the hotspots will help to obtain a proper management program and consequently preserve the biodiversity of this area.

A bibliography and review of the published records of species from several Microlepidoptera families in Croatia are presented. Altogether 274 species from eight superfamilies, 12 families and 55 genera of Microlepidoptera occurring in Croatia are presented. The paper is a summarization of available published records, from historical publications to recent studies. It also includes material collected during field surveys conducted by the second and third author in 2018 and 2019 in Croatia. Eight out of the 61 recorded species were not previously reported from that country and are considered new to its fauna. Furthermore, the findings of 10 species reconfirm their occurrence in the fauna of Croatia, as they are the first recent records in 100 years or more. Except for the families Pyralidae and Crambidae, no checklists for Croatian microlepidopterous families have been published in the form of journal articles. This paper represents a first summary of available published records and a first species list of the families Micropterigidae, Eriocraniidae, Hepialidae, Nepticulidae, Opostegidae, Heliozelidae, Adelidae, Prodoxidae, Incurvariidae and Tischeriidae, and Alucitidae and Pterophoridae in Croatia. By making data about the occurrence of species from these families in Croatia available, this list is a major contribution to the overall knowledge of the Croatian fauna of Microlepidoptera. It aims at increasing the interest in these micromoth families in that country and inspiring future research into this group. It is also hoped that it will encourage the creation of checklists of these microlepidopterous families or even all micromoths in Croatia.

And it is examined Tobin's Q ratio values on 31 March, 30 June, 30 September, 31 December and at the time of the announcement of the audit report. Also it is examined the firm's stock price on the date of the audit firm's opinion, on the date of the one day before and after it.Discussion –As a result of the research, it has been revealed that audit opinions do not affect the Tobin’s Q ratio but affect stock price of companies in Turkey.
Hastaların Ortopedi Kliniği Tercihlerini Etkileyen Faktörlerin AHPYöntemi ile Belirlenmesi (Determining the Factors Affecting Patients Orthopedic Clinic Preferences Through AHP Method)
Authors: Gergin Mutlu , Çelik Bahar
Published: July 2023

Amaç –Çalışmanın amacı hastaların, Kütahya’da faaliyet gösteren üç ayrı hastanenin ortopedi kliniğinin hangisini tercih ettiklerini ve bu tercihte hangi kriterleri öncelediklerini tespit etmektir.Yöntem –Çalışmada üç alternatif (A Hastanesi Ortopedi Kliniği, B Hastanesi Ortopedi Kliniği ve C Hastanesi Ortopedi Kliniği) ve dört kriter (Doktorlar, Tedavi Sarf (Medikal) Malzemeleri,Hizmet Kalitesi ve Ulaşım-İletişim Kolaylığı) kullanılmıştır. Çalışmanın ilk aşamasında karar vericilerin (hizmet alıcıların) hem kriterlere hem de kriterlere göre alternatifleri kıyaslamalarına yönelik sözel değerlendirmeleri alınmıştır. Çalışmada Thomas L. Saaty (1988) tarafından geliştirilen, kıyaslama yaparak ikiden fazla kriter arasından seçim yapma imkanı sunan ve çok kriterli karar verme tekniklerinden biri olan Analitik Hiyerarşi Süreci (AHP) yöntemi kullanılmıştır.Bulgular –Çalışma sonunda, bir hastanenin ortopedi klininğinin tercih edilmesinde “Doktorlar”ın en yüksek önem derecesine sahip olduğu tespit edilmiştir. Ayrıca, üç alternatif arasından A hastanesinin ortopedi kliniğinin en yüksek düzeyde önem derecesine sahip olduğu, A alternatifinin “Tedavi Sarf (Medikal) Malzemeleri” ve “Ulaşım-İletişim Kolaylığı” kriterleri açısından diğer iki alternatife göre daha yüksek düzeyde puan aldığı anlaşılmıştır.Tartışma –Çalışmadan elde edilen bulgulara göre bireyler bir hastanenin ortopedi kliniğini tercih ederken o hastanede çalışan doktorun tecrübesine ve bilgisine bakarak hareket etmektedirler. Sağlık hizmeti verilirken kullanılan sarf malzemelerin kalitesi, hastanın kabulünden taburcu olduğu ana kendisine verilen hizmetin kalitesi de yine bu kliniğin tercih edilmesinde önemli bir etkendir. Dördüncü kriter olan ulaşım/iletişim kolaylığının düşük olduğu gözlemlenmiştir. Bu da, ihtiyaç duyulan sağlık hizmetinin lokasyonundan ziyade verilen hizmetin kalitesinin daha önemli olduğunu, bireylerin sağlık hizmetinin konumu uzak dahi olsa iyi bir sağlık hizmeti veren kurumu tercih ettiğini ve mesafe maliyetine katlandığını göstermektedir

Published: July 2023

Em Manaus, os estudos de voçorocas vêm sendo realizados desde meados da década de 90 do século XX em que vários deles utilizaram técnicas de monitoramento. Este artigo visa abordar e descrever as técnicas de monitoramento utilizadas nas voçorocas da Região Metropolitana de Manaus (RMM). A análise dos trabalhos permitiu constatar que os monitoramentos objetivaram, sobretudo, estimar as taxas de erosão e predizer sua evolução e de compreender seus mecanismos, processos e as consequências ambientais e sociais decorrentes.  E que as técnicas de monitoramento analisadas podem ser distribuídas em 4 grupos, quanto ao uso dos instrumentos: 1o) trena, bússola, ficha cadastral e croqui; 2o) poligonais planimétricas; 3o) imagens de satélite e do Google Earth; 4o) imagens de alta resolução espacial via veículos aéreos não tripulados (VANTs). Concluiu-se que a utilização de técnicas de monitoramento mais modernas, como o uso das imagens de VANTs, não necessariamente exclui o uso de procedimentos mais simples, como o uso das fichas cadastrais, trena e bússola e que a combinação de diferentes técnicas pode auxiliar no melhor detalhamento e caracterização morfométrica da voçoroca monitorada, assim como das feições secundárias envolvidas.
Técnicas de manejo voltadas à recuperação de áreas degradadas por erosão: Análise de 15 anos de estudos na voçoroca da Fazenda Experimental do Campus Glória-UFU

Published: July 2023

O presente artigo é resultado do acompanhamento da dinâmica natural de evolução e aplicação de experimentos de recuperação de áreas degradadas no interior e entorno de uma voçoroca situada na Fazenda Experimental do Campus Glória, pertencente à Universidade Federal de Uberlândia, em Uberlândia - MG. Esta feição erosiva encontra-se em estágio avançado de evolução, com afloramento do lençol freático, paredes abruptas e cabeceira íngreme. O acompanhamento através de várias pesquisas realizadas na área perfaz um período de 15 anos, com implementação de testes experimentais de recuperação no entorno e interior da forma erosiva, que objetivaram mensurar os resultados das intervenções propostas, seja de caráter físico, edáfico ou biótico. Os estudos demonstraram que a evolução de uma voçoroca é um processo complexo, que no ambiente de clima tropical sazonal, com invernos secos e verões chuvosos, tem íntima correlação com os processos pluviométricos, sendo condicionado pela geometria das vertentes e interação solo-água. Conjuntamente foi observado o intenso papel das atividades antrópicas, que diretamente através de técnicas de manejo geram impactos positivos na recuperação do passivo, ou indiretamente, promovendo sua intensificação por meio de incêndios em regiões adjacentes, que podem interferir negativamente no processo de recuperação, removendo práticas de manejo conservacionistas já adotadas.

Uma parte da história ambiental do noroeste paranaense está refletida na paisagem pela presença de paleovoçorocas de grande magnitude, ao norte do rio Ivaí, cuja gênese pode estar associada à condição climática distinta da atual, ao longo do Quaternário. Estudos na região têm apontado variações climáticas ao longo do Holoceno, indicando período mais seco que o atual nas transições Pleistoceno/Holoceno e Holoceno Médio/Holoceno Superior. Embora esses estudos indiquem que as taxas de denudação forneçam uma estimativa do período de início de formação dessas feições, as condições ambientais de clima e vegetação que permitiram o desenvolvimento de tais processos ainda são pouco conhecidas. Partindo da concepção do solo como um reservatório de registros ambientais, e adotando uma abordagem multiproxy, o presente estudo tem como objetivo reconstituir as condições paleaombientais holocênicas que favoreceram o desenvolvimento de uma paleovoçoroca no município de Loanda, noroeste paranaense. De acordo com os resultados, o desenvolvimento dessa feição está relacionado a um ambiente com vegetação mais aberta que a atual, sensivelmente mais seco e com temperatura mais amena, durante a transição Holoceno Médio/Superior. O aumento da umidade no Holoceno Superior favoreceu, incialmente, a ampliação da erosão e, posteriormente, já com dimensões quilométricas, sua estabilização com o avanço da floresta.
Role of artificial intelligence in pancreatic cystic neoplasms: modernizing the identification and longitudinal management of pancreatic cysts
Authors: Langan Russell C. , Pitt Henry A. , Schneider Erika
Published: July 2023

Mucinous cysts of the pancreas represent the most common identifiable precursor to pancreatic cancer. Evidence-based guidelines for screening and surveillance exist, but many patients are either not properly identified or lost to follow-up. Artificial Intelligence, specifically computational linguistics models, can dramatically improve patient identification and mitigate risk through modernizing pancreatic cyst longitudinal surveillance. Herein we discuss the risk associated with mucinous cysts of the pancreas and modern approaches to patient identification and follow-up.

Published: July 2023

This paper presents a fixed-time integral sliding mode control scheme for a nonholonomic wheeled mobile robot (WMR). To achieve the trajectory tracking mission, the dynamic model of a WMR is first transformed into a second-order attitude subsystem and a third-order position subsystem. Two novel continuous fixed-time disturbance observers are proposed to estimate the external disturbances of the two subsystems, respectively. Then, trajectory tracking controllers are designed for two subsystems by utilizing the reconstructed information obtained from the disturbance observers. Additionally, an auxiliary variable that incorporates the Gaussian error function is introduced to address the chattering problem of the control system. Finally, the proposed control scheme is validated by a wheeled mobile robotic experimental platform.

Despite the significant advances achieved in recent years, the development of efficient electrolyte additives to mitigate the performance degradation during long-term cycling of high-energy density lithium||nickel-rich (Li||Ni-rich) batteries remains a significant challenge. To achieve a rational design of electrolytes and avoid unnecessary waste of resources due to trial and error, it is crucial to have a comprehensive understanding of the underlying mechanism of key electrolyte components, including salts, solvents, and additives. Herein, we present the utilization of lithium difluoro(oxalate) borate (B) (LiDFOB), a B-containing lithium salt, as a functional additive for Li||LiNi0.85Co0.1Mn0.05O2 (NCM85) batteries, and comprehensively investigate its mechanism of action towards enhancing the stability of both anode and cathode interfaces. The preferential reduction and oxidation decomposition of DFOB- leads to the formation of a robust and highly electronically insulating boron-rich interfacial film on the surface of both the Li anode and NCM85 cathode. This film effectively suppresses the consumption of active lithium and the severe decomposition of the electrolyte. Furthermore, the presence of B elements in the cathode-electrolyte interfacial film, such as BF3, BF2OH, and BF2OBF2 compounds, can coordinate with the lattice oxygen of the cathode, forming strong coordination bonds. This can significantly alleviate lattice oxygen loss and mitigate detrimental structural degradation of the Ni-rich cathode. Consequently, the Li||NCM85 battery cycled in LiDFOB-containing electrolyte displays superior capacity retention of 74% after 300 cycles, even at a high charge cut-off voltage of 4.6 V. The comprehensive analysis of the working mechanisms of LiDFOB offers valuable insights for the rational design of electrolytes featuring multifunctional lithium salts or additives for high energy density lithium metal batteries.

Aim: In recent years, there has been a growing interest in the therapeutic potential of plant-derived miRNAs, which have been considered new bioactive ingredients in medicinal plants. Viscum album L., commonly used as an adjuvant cancer therapy in central Europe, contains a large number of miRNAs associated with human diseases such as cancer, cardiovascular diseases, and neurological disorders. This study aimed to investigate whether mistletoe miRNAs, specifically val-miR218, exert anti-cancer activity against osteosarcoma. Methods: The anti-cancer effects of miRNAs from V. album L. were evaluated. The targets of val-miR218 were identified by RNA-seq. The mRNA and protein expression of the targets was confirmed by RT-qPCR and western blot analyses. The interaction between the val-miR218 and miRNA recognition elements (MREs) was validated by the dual-luciferase assay. The inhibitory effect of val-miR218 against osteosarcoma was investigated in vivo. Results: Among these abundant miRNAs in V. album L., val-miR218 showed high potential anti-cancer effects against osteosarcoma. To clarify its molecular mechanism of action, we sequenced val-miR218 associated RNAs and their down-regulated RNAs. As a result, 61 genes were considered the direct targets of val-miR218. Interestingly, these targets were related to essential cellular functions such as cell cycle, DNA replication, and cell morphology, suggesting that val-miR218 significantly inhibited cell growth and arrested osteosarcoma cells in G0/G1 phase by influencing basic cell activities. Mistletoe extracellular vesicles offered val-miR218 adequate protection and facilitated the uptake of val-miR281 by human cells. Moreover, val-miR218 showed significant anti-tumor effects in vivo. Conclusion: This study demonstrated the significant potential of val-miR218 regarding proliferation inhibition in various tumor cell lines in vitro and for osteosarcoma in vivo. Due to the increasing problems during chemotherapy, new therapeutic approaches are becoming more critical. The significant anti-cancer effects of medicinal plants derived miRNAs indicate a promising therapeutic strategy for treating cancer.
Reinforcement learning with parameterized action space and sparse reward for UAV navigation
Authors: Feng Shiying , Li Xiaofeng , Ren Lu , Xu Shuiqing
Published: July 2023

Autonomous navigation of unmanned aerial vehicles (UAVs) is widely used in building rescue systems. As the complexity of the task increases, traditional methods based on environment models are hard to apply. In this paper, a reinforcement learning (RL) algorithm is proposed to solve the UAV navigation problem. The UAV navigation task is modeled as a Markov Decision Process (MDP) with parameterized actions. In addition, the sparse reward problem is also taken into account. To address these issues, we develop the HER-MPDQN by combining Multi-Pass Deep Q-Network (MP-DQN) and Hindsight Experience Replay (HER). Two UAV navigation simulation environments with progressive difficulty are constructed to evaluate our method. The results show that HER-MPDQN outperforms other baselines in relatively simple tasks. Especially for complex tasks involving relay operations, only our method can achieve satisfactory performance.
