Peranan Modal Sosial Bagi Petani Miskin untuk Mempertahankan Kelangsungan Hidup Rumah Tangga di Pedesaan Ngawi (Studi Kasus di Desa Randusongo Kecamatan Gerih Kabupaten Ngawi Provinsi Jawa Timur)
This study was a descriptive qualitative research aiming to describe the role of Social Capital for the poor farmer to sustain their household life. The subject of research consisted of poor farmers having a less-than-0.13 ha land conducted in RT 4 RW 6 Bulu II Hamlet, Randusongo Village, Gerih Subdistrict, Ngawi Regency, East Java Province.This study was conducted using in-depth interview, observation, and library study techniques. Meanwhile, the sampling technique used was maximum variation sampling taken seven informants as the sample, consisting of four informants: poor old, very poor old, poor young, and very poor young farmers, as the case informant, while the key informant of research consisted of: elders of Randusongo Village, Carik/Secretary of Randusongo Village, and Head of Bulu II Hamlet. Key informant was also used as the instrument of validating the field data from the informant.The case informants were selected based on the criterion specified by Statistical Central Agency (BPS), that was, those belonging to poor family, while key informants were the village elders considered as knowledgeable and understanding about the daily condition of poor farmers because they domiciled in the same hamlet, and the village apparatus considered as knowing the poor farmers' condition because they often gave them service regarding Bantuan Langsung Tunai ((BLT= Cash Direct Grant) now called Bantuan Langsung Sementara Masyarakat (BLSM = Temporary Public Grant), Raskin (rice for poor people) and other services.The result showed that bonding social capital played an important role for the poor farmers in sustaining their household life. It could be seen from those helping their poor close relatives in meeting their daily life needs. Bridging social capital is the strongest out of the three social capitals existing because many poor farmer household could survive because of their close neighbor's help. Linking social capital did not play a role at al because such organization as PKK (Pendidikan Kesejahteraan Keluarga = Family Welfare Education) or organization at either RT or RW level in Randusongo village did not work thereby could not contribute to reinforcing social capital within the society

About randomised distributed graph colouring and graph partition algorithms
AbstractWe present and analyse a very simple randomised distributed vertex colouring algorithm for arbitrary graphs of size n that halts in time O(logn) with probability 1-o(n-1). Each message containing 1 bit, its bit complexity per channel is O(logn).From this algorithm, we deduce and analyse a randomised distributed vertex colouring algorithm for arbitrary graphs of maximum degree Δ and size n that uses at most Δ+1 colours and halts in time O(logn) with probability 1-o(n-1).We also obtain a partition algorithm for arbitrary graphs of size n that builds a spanning forest in time O(logn) with probability 1-o(n-1). We study some parameters such as the number, the size and the radius of trees of the spanning forest
Modeling Low Energy Demand Futures for Buildings: Current State and Research Needs
Buildings are key in supporting human activities and well-being by providing shelter and other important services to their users. Buildings are, however, also responsible for major energy use and greenhouse gas (GHG) emissions during their life cycle. Improving the quality of services provided by buildings while reaching low energy demand (LED) levels is crucial for climate and sustainability targets. Building sector models have become essential tools for decision support on strategies to reduce energy demand and GHG emissions. Yet current models have significant limitations in their ability to assess the transformations required for LED. We review building sector models ranging from the subnational to the global scale to identify best practices and critical gaps in representing transformations toward LED futures. We focus on three key dimensions of intervention (socio-behavioral, infrastructural, and technological), three megatrends (digitalization, sharing economy, and circular economy), and decent living standards. This review recommends the model developments needed to better assess LED transformations in buildings and support decision-making toward sustainability targets
Flexural behavior of Sisal/Castor oil-Based Polyurethane and Sisal/Phenolic Composites
Impact of alternative solid state forms and specific surface area of high-dose, hydrophilic active pharmaceutical ingredients on tabletability
YesIn order to investigate the effect of using different
solid state forms and specific surface area (TBET) of active
pharmaceutical ingredients on tabletability and dissolution
performance, the mono- and dihydrated crystalline forms of
chlorothiazide sodium and chlorothiazide potassium (CTZK)
salts were compared to alternative anhydrous and amorphous
forms, as well as to amorphous microparticles of chlorothiazide
sodium and potassium which were produced by spray drying and
had a large specific surface area. The tablet hardness and tensile
strength, porosity, and specific surface area of single-component,
convex tablets prepared at different compression pressures were characterized. Results confirmed the complexity of the
compressibility mechanisms. In general it may be concluded that factors such as solid-state form (crystalline vs amorphous), type
of hydration (presence of interstitial molecules of water, dehydrates), or specific surface area of the material have a direct impact
on the tabletability of the powder. It was observed that, for powders of the same solid state form, those with a larger specific
surface area compacted well, and better than powders of a lower surface area, even at relatively low compression pressures.
Compacts prepared at lower compression pressures from high surface area porous microparticles presented the shortest times to
dissolve, when compared with compacts made of equivalent materials, which had to be compressed at higher compression
pressures in order to obtain satisfactory compacts. Therefore, materials composed of nanoparticulate microparticles (NPMPs)
may be considered as suitable for direct compaction and possibly for inclusion in tablet formulations as bulking agents, APIs,
carriers, or binders due to their good compactibility performanceSolid State Pharmaceutical Cluster (SSPC), supported by Science Foundation Ireland under Grant No. 07/SRC/B1158
Annex III: Scenarios and modelling methods
The use of scenarios and modelling methods are pillars in IPCC Working Group III (WGIII) Assessment Reports. Past WGIII assessment report cycles identified knowledge gaps about the integration of modelling across scales and disciplines, mainly between global integrated assessment modelling methods and bottom-up modelling insights of mitigation responses. The need to improve the transparency of model assumptions and enhance the communication of scenario results was also recognised. This annex on Scenarios and Modelling Methods aims to address some of these gaps by detailing the modelling frameworks applied in the WGIII Sixth Assessment Report (AR6) chapters and disclose scenario assumptions and its key parameters. It has been explicitly included in the Scoping Meeting Report of the WGIII contribution to the AR6 and approved by the IPCC Panel at the 46th Session of the Panel
A review of trends and drivers of greenhouse gas emissions by sector from 1990 to 2018
Global greenhouse gas (GHG) emissions can be traced to five economic sectors: energy, industry, buildings, transport and AFOLU (agriculture, forestry and other land uses). In this topical review, we synthesise the literature to explain recent trends in global and regional emissions in each of these sectors. To contextualise our review, we present estimates of GHG emissions trends by sector from 1990 to 2018, describing the major sources of emissions growth, stability and decline across ten global regions. Overall, the literature and data emphasise that progress towards reducing GHG emissions has been limited. The prominent global pattern is a continuation of underlying drivers with few signs of emerging limits to demand, nor of a deep shift towards the delivery of low and zero carbon services across sectors. We observe a moderate decarbonisation of energy systems in Europe and North America, driven by fuel switching and the increasing penetration of renewables. By contrast, in rapidly industrialising regions, fossil-based energy systems have continuously expanded, only very recently slowing down in their growth. Strong demand for materials, floor area, energy services and travel have driven emissions growth in the industry, buildings and transport sectors, particularly in Eastern Asia, Southern Asia and South-East Asia. An expansion of agriculture into carbon-dense tropical forest areas has driven recent increases in AFOLU emissions in Latin America, South-East Asia and Africa. Identifying, understanding, and tackling the most persistent and climate-damaging trends across sectors is a fundamental concern for research and policy as humanity treads deeper into the Anthropocene
Autoantibodies neutralizing type I IFNs are present in ~4% of uninfected individuals over 70 years old and account for ~20% of COVID-19 deaths
Publisher Copyright: © 2021 The Authors, some rights reserved.Circulating autoantibodies (auto-Abs) neutralizing high concentrations (10 ng/ml; in plasma diluted 1:10) of IFN-alpha and/or IFN-omega are found in about 10% of patients with critical COVID-19 (coronavirus disease 2019) pneumonia but not in individuals with asymptomatic infections. We detect auto-Abs neutralizing 100-fold lower, more physiological, concentrations of IFN-alpha and/or IFN-omega (100 pg/ml; in 1:10 dilutions of plasma) in 13.6% of 3595 patients with critical COVID-19, including 21% of 374 patients >80 years, and 6.5% of 522 patients with severe COVID-19. These antibodies are also detected in 18% of the 1124 deceased patients (aged 20 days to 99 years; mean: 70 years). Moreover, another 1.3% of patients with critical COVID-19 and 0.9% of the deceased patients have auto-Abs neutralizing high concentrations of IFN-beta. We also show, in a sample of 34,159 uninfected individuals from the general population, that auto-Abs neutralizing high concentrations of IFN-alpha and/or IFN-omega are present in 0.18% of individuals between 18 and 69 years, 1.1% between 70 and 79 years, and 3.4% >80 years. Moreover, the proportion of individuals carrying auto-Abs neutralizing lower concentrations is greater in a subsample of 10,778 uninfected individuals: 1% of individuals 80 years. By contrast, auto-Abs neutralizing IFN-beta do not become more frequent with age. Auto-Abs neutralizing type I IFNs predate SARS-CoV-2 infection and sharply increase in prevalence after the age of 70 years. They account for about 20% of both critical COVID-19 cases in the over 80s and total fatal COVID-19 cases.Peer reviewe
