Hasil penelitian menunjukan masyarakat menilai tingkat kepuasan terhadap kinerja 24 atribut, skor rata-ratanya sebesar 3,14 (Kategori cukup puas: 2,60-3,39). Sedangkan skor rata-rata tingkat kepentingannya, sebesar 4,20 (Kategori sangat penting: 4,20-5,00). Serta skor indeks kepuasan masyarakat (IKM) adalah 0,63 dengan kriteria “cukup puas” (kriteria cukup puas: 0,51-0,65). Harapan masyarakat pada program ini adalah pada program pengolahan hasil perikanan yaitu masyarakat berharap dibantu alat simpan Frezer yang cukup besar agar mampu menampung ikan lebih banyak saat musim ikan. Pada peternakan ayam, kesamaan perlakuan mendapatkan bantuan seperti peralatan sarana produksi kepada seluruh anggota kelompok. Budidaya perikanan, manfaat berupa meningkatnya pendapatan petani dirasa masih belum sesuai harapan, karena terkendala pemasaran hasil perikanan terutama di Desa Karang Rejo. Masyarakat berharap perusahaan membantu pemasaran maupun menyerap sendiri hasil perikanan. Perkebunan pisang, manfaat berupa meningkatnya pendapatan petani dirasa masih belum sesuai harapan karena masih minimnya pendapatan dari perkebuanan pisang. Pisang baru menghasilkan apabila usianya telah 1 tahun lebih. Untuk mengatasi kendala itu masyarakat menyarankan tumpang sari. Pembuatan pupuk bokashi, masyarakat ingin bisa mengetahui anggaran pembinaan. Dengan diketahuinya anggaran, masyarakat dapat melakukan perencanaan dan pengembangan yang lebih baik dangan mempertimbangkan alokasi anggaran.Kata kunci: indeks kepuasan masyarakat, CSR pemberdayaan, analisis tingkat kinerja kepentingan, analisis tingkat kesesuaian, analisis kuadran.

Abstrak. Desa Artain adalah desa yang terletak di Kecamatan Aranio dengan luas wilayah 70,00 km2 (7.000 ha). Dari data Desa Artain yang paling luas lahannya adalah tanaman padi gogo sebesar 250 ha dibandingkan lahan pertanian yang lain. Namun produktivitas padi gogo di Desa Artain masih rendah yang pertama disebabkan oleh kurangnya minat petani dalam menggunakan pupuk organik. Penyebab yang kedua yaitu petani kurang berminat untuk melakukan pemupukan berimbang pada tanaman padi gogo. Penelitian ini dilaksanakan di Desa Artain selama lebih kurang enam bulan dari bulan Februari sampai dengan bulan Juli 2018. Metode pengambilan sampel dilakukan dengan menggunakan metode simple random sampling, yaitu sebanyak 34 petani. Hasil penelitian menunjukan bahwa ada 2 persepsi petani yaitu : persepsi petani terhadap pupuk organik pada tanaman padi gogo tergolong sangat buruk dan persepsi petani terhadap pemupukan berimbang tergolong buruk. Oleh karena itu, ditingkatkan untuk dilakukan penyuluhan atau pelatihan tentang pupuk organik dan pemupukan berimbang. Kata kunci: petani, tanaman padi gogo, persepsi, pupuk organik, pemupukan berimbang

A detrital signal of glaciation in the Sierra Nevada, California, U.S.A.
Authors: Sickmann Zachary T. , Malkowski Matthew A. 
Published: December 2024

ABSTRACT
Alpine glaciers are sensitive indicators of regional environmental conditions over a variety of temporal scales, from interdecadal to glacial–interglacial timescales. However, cycles of major alpine glaciation events are often difficult to define through time due to the inherent tendency of later glacial advances to erase the records of previous cycles. More distal sedimentary records of detritus shed from glaciated ranges offer integrated archives of glacial cycles through time if a region produces a distinct detrital signal of glaciation. The Sierra Nevada range in California, where regional latitudinal climate shifts closely align with latitudinal trends in bedrock geology, offers an excellent example of such a distinct glaciation signal in marine sediment provenance signatures. In this study, we examine changes in sand provenance signatures across samples from the deepwater continental slope (Last Glacial Maximum sediment), outer continental shelf (late Pleistocene–early Holocene sediment), and the central (mixed late Pleistocene to Holocene sediment) and bayhead (mid.–late Holocene sediment) regions of San Francisco Bay. Sediment from slope and shelf samples shows a strong central-southern Sierra Nevada Batholith affinity suggesting derivation from the Sierra Nevada when the range was glaciated during the latest Pleistocene. In contrast, mid- to late-Holocene bayhead samples show a strong northern Sierran affinity indicating that they were originally eroded from the Sierras after deglaciation. These results are consistent with the locus of erosion in the Sierras shifting from higher-elevation glaciated areas in the central and southern range when a rangewide ice cap was present through the latest Pleistocene toward the lower-elevation northern Sierras after rangewide deglaciation around 13 ka as precipitation patterns shifted north through the Holocene. This detrital signal of Sierra Nevada glacial cycles could prove useful in future efforts to better define the currently incomplete history of Quaternary glaciations in the region and serve as an analog to other regions globally.
Frictional Characteristics of Granite Fault under Imposed Dynamic Normal Disturbance Loads
Authors: Cui Guojian , Zhang Chuanqing , Xie Qiming 
Published: December 2024

Abstract
Fault activation induced by dynamic normal disturbance loads resulting from activities such as blasting, excavation, and earthquakes has the potential to trigger significant geological disasters, such as rock bursts, posing a threat to the stability and safety of rock engineering projects. In this study, we report on laboratory experiments to investigate the response of simulated faults. These experiments involved the use of bare granite surfaces to mimic fault behavior, while considering various initial stress ratios and applied normal disturbance loads. The application of normal disturbance loads led to the generation of consistent oscillations in shear stress, apparent friction coefficient, normal displacement, and shear displacement for both inactive and active faults. The experimental results suggest that the activation of faults can indeed be induced by applied normal disturbance loads, and larger initial stress ratios and disturbance loads tend to promote the activation of these simulated faults. Furthermore, we explored the effects of initial normal stress, initial shear stress, disturbance amplitude, and disturbance frequency on the primary quantified parameters associated with the simulated fault. Additionally, we conducted a preliminary discussion on the slip mechanisms of the simulated fault under dynamic normal disturbance loading and its potential engineering implications.

Abstract

In this study, we systematically evaluated the efficacy of chemical modifications in enhancing the translational activity and stability of mRNA. We employed a primarily chemistry-based synthetic approach for the modified mRNA, which is crucial for the position-specific introduction of chemical modifications, enabling an intricate and detailed structure-activity relationship (SAR) study, hitherto unattainable with conventional methods. A pivotal innovation herein was the introduction of 2´-F modification for the nucleosugar in the open reading framework (ORF) at a site-specific position within the codon unit (the first nucleoside in the codon unit, 1st NC), which significantly bolstered the biological stability of mRNA without compromising its translational activity. This precise control of chemical modification patterns has emerged as a key to achieving higher peptide expression levels than conventional in vitro-transcribed mRNA. Further evaluations of the modifications at the 5´-UTR and poly(A) tail with other types of nucleoside and phosphate analogs also exemplified the importance of terminal modifications on mRNA for improved translational activity. These findings offer a novel framework for molecular design and development of effective mRNA-based therapeutics.
Determination of the critical particle size distribution of non-crystalline potassium nitrate, sodium nitrate and mixtures thereof as non-oxidizing solid material
Authors: Mak Wim , Trigo Pablo Olivares , Holwerda Harmen Tjalling 
Published: December 2024

Abstract

Only from production lot-specific analysis it is known that the oxidizing properties of non-crystalline (i.e., prill, granule) potassium nitrate and sodium nitrate depend on their particle size. Both substances are exempted from the hazard classification as oxidizing solid for the maritime transport, provided that the conditions of Special Provision 964 in the IMDG Code are met, which requires appropriate sampling, testing and certification of these materials. In commercial practice, these requirements are laborious, time-consuming and costly as each cargo needs to be tested before its departure from the port of loading or practically impossible when no qualified lab is present in the country of origin. In this systematic study the critical particle size distribution of these substances for their hazard classification as non-oxidizing solid was defined as a particle size distribution consisting of minimum 95% of the total sample mass > 1.0 mm sieve size, with maximum 2.5% between 0.85-1.0 mm, and with maximum 2.5% < 0.85 mm, respectively. This study provides empirical evidence for an easy-to-apply, reliable, and cost-efficient granulometry test for the hazard classification of these substances as non-oxidizing solid material that can serve as an alternative to the methods applied so far.

Published: December 2024

Abstract

Several bronzes, casting moulds, crucible walls, copper slag, and other confirmed relics of copper casting from the late Spring and Autumn period and early Warring States period (circa 475 BCE) were unearthed at the Datongpu Site in Jianhu County, Jiangsu Province, between 2019 and 2021. Scanning electron microscopy coupled with energy-dispersive spectroscopy, energy-dispersive X-ray fluorescence spectrometry, and multicollector–inductively coupled plasma mass spectrometry were employed to examine the metal resources and mould-making technology of the bronze casting industry of the Yue culture during the Eastern Zhou Dynasty. The metal particles in the slag suggest that the melted alloy product is high-tin bronze, and the ceramic mould contained a significant amount of plant debris. This indicates that the casting technology involving high-tin bronze alloy production and the use of plant ash in moulds is characteristic of the lower Yangtze River region, highlighting the northward spread of Yue culture. Accordingly, the lead materials at Datongpu were predominantly sourced from the Central Plains, confirming the records of the relationship between Jin and Yue in the early Warring States period. The findings highlight the technological advancements of the Yue culture and support historical accounts of interactions between the Jin and Yue states. This study is significant as it provides new insights into the technological and material aspects of the bronze casting industry during the Eastern Zhou Dynasty, which is crucial for understanding regional metallurgical practices and cultural interactions.
Smart Oxygen Monitoring in Hospitals: A Pilot Study during COVID-19
Authors: Velicka Jan , Pies Martin , Hajovsky Radovan , Barnova Katerina , Martinek Radek 
Published: December 2024

Abstract

During the COVID-19 pandemic from 2020 to 2021, there were up to twice as many oxygen-related fires and explosions in hospitals compared to non-pandemic times. This was likely due to the hospitals' insufficient preparedness for the sudden increase in ventilator use during oxygen therapies for severely ill patients with COVID-19. The pandemic has thus shown the need to consider departments working with medical oxygen as potentially dangerous and to introduce systemic measures that can eliminate these life-threatening risks. A promising solution to prevent oxygen-related fires is the use of a proposed smart measurement system that can accurately and timely detect increased oxygen concentrations in hospitals. The wireless device is based on the Internet of Things technology and meets the requirements for long-term and low power consumption monitoring within a hospital environment. Oxygen concentrations were measured at regular intervals, and the collected data was wirelessly transmitted to a database repository. If the set oxygen concentration threshold was exceeded, hospital staff were reliably notified via short message service and e-mail. The accuracy of the monitoring system was ± 1% and the consumption of the sensor module was approximately 345 μA when the measured oxygen concentration was requested every minute. The proposed system can be used in rooms designated for oxygen therapy, as well as in standard rooms such as hospital corridors or patient rooms in case of emergencies.
Mechanism of quercetin in the treatment of endometriosis based on network pharmacology and transcriptome sequencing

Published: December 2024

Abstract

This study explores how quercetin may treat endometriosis (EMs) by combining network pharmacology and transcriptome sequencing approaches. Through network pharmacology, 132 shared targets between quercetin and EMs were identified, with KEGG pathway analysis suggesting that the MAPK signaling pathway could be a significant therapeutic target. Transcriptome sequencing revealed that PDGFRB was highly expressed in ectopic endometrial tissue, a finding confirmed by immunohistochemistry (IHC) showing elevated levels of PDGFRB, RAS, RAF1, and ERK1/2 in ectopic lesions. In an EMs mouse model, quercetin treatment led to a marked reduction in ectopic lesion volume, lowered adhesion scores, and decreased expression of PDGFRB, RAS, RAF1, and ERK1/2 in endometrial tissues. Additionally, the knockdown of PDGFRB in endometriosis cells inhibited their proliferation, invasion, and migration, processes critical to EMs pathology. Quercetin treatment further suppressed cell viability and downregulated the protein expression of RAS, phosphorylated RAF1, RAF1, phosphorylated ERK, and ERK1/2. These findings collectively suggest that quercetin exerts its therapeutic effect in endometriosis by regulating the MAPK signaling pathway via PDGFRB, thereby reducing EMs cell proliferation, invasion, and migration. This study provides insights into quercetin’s multi-targeted mechanism of action in endometriosis treatment.

Abstract

Phenolic compounds, known for their antioxidant and antifungal properties may be connected to infection processes of Cronartium rusts in alternate host plants. We studied changes in leaf chemistry after Cronartium inoculation on susceptible alternate hosts of C. pini and C. ribicola. Impatiens balsamina and Paeonia lactiflora were inoculated with C. pini, and R. nigrum with C. ribicola in the greenhouse. Leaves of the inoculated plants were harvested 3 and 6 days after inoculation for chemical analysis, which was done using LC-MS (liquid chromatography mass spectrometry). Species-specific differences were found in dominant phenolics ferulic acid, hyperoside, quercitrin, and rutin. Rust inoculation produced limited changes in phenolic concentrations, with significant increases only in p-coumaric acid in I. balsamina and rutin in R. nigrum. Significant post-inoculation decrease was found in several cases. While phenolic fluctuations varied by species and incubation time, there was no significant interaction between inoculation and incubation time, suggesting the absence of induced phenolic accumulation during early infection stages. The results support the hypothesis that susceptible alternate hosts exhibit weak, delayed phenolic defenses, possibly due to rust virulence factors suppressing these responses. Indirectly, they provide support for the defensive role of phenolics in resistant congeneric hosts, emphasizing also the importance of further molecular studies to explore plant defense mechanisms against rust pathogens.
