One of the best management practices (BMPs) for stormwater quality and quantity control is a bioretention system. The removal efficiency of different pollutants under this system is generally satisfactory, except for nitrogen which is deficient in certain bioretention systems. Nitrogen has a complex biogeochemical cycle, and thus the removal processes of nitrogen are typically slower than other pollutants. This study summarizes recent studies that have focused on nitrogen removal for urban stormwater runoff and discusses the latest advances in bioretention systems. The performance, influencing factors, and design enhancements are comprehensively reviewed in this paper. The review of current literature reveals that a bioretention system shows great promise due to its ability to remove nitrogen from stormwater runoff. Combining nitrification and denitrification zones with the addition of a carbon source and selecting different plant species promote nitrogen removal. Nevertheless, more studies on nitrogen transformations in a bioretention system and the relationships between different design factors need to be undertaken.
Understanding Consumers’ Purchase Intention for Online Paid Knowledge: A Customer Value Perspective
Authors: Su Luyan , Li Ying , Li Wenli
Published: September 2019

Online knowledge platforms have been undergoing a transformation from providing free knowledge to online paid knowledge (OPK). As customers play a key role in the sustainable development and success of the new business model, we focused on the factors that drive consumers’ online knowledge purchase intention. Drawing on the cognitive–affective–conative framework and customer value theory, we propose that consumers rationally evaluate the customer values of OPK in the cognitive stage, followed by generating trust and identification in the affective stage, then leading to a purchase decision. Six factors were extracted from three dimensions of customer value: Functional, emotional, and social values. The hypotheses were tested using survey data obtained from 504 respondents using structural equation modeling. The findings confirm that customer value and identification with the knowledge contributor significantly influence trust in OPK. Trust in OPK and identification with the knowledge contributor both significantly influence purchase intention, whereas trust in the platform neither influences consumers’ trust in OPK nor purchase intention. The findings of this study will help OPK platforms to increase their sales of knowledge products.

Published: September 2019

Biofuel production by oleaginous microalgae is a promising alternative to the conventional fossil fuels. Many microalgae species have been investigated and deemed as potential renewable sources for the production of biofuel, biogas, food supplements and other products. Oleaginous microalgae, named for their ability to produce oil, are reported to store 30–70% of lipid content due to its metabolic properties under nutrient starvation conditions. This review presents the assortment of the research studies focused on biofuel production from oleaginous microalgae. The new methods and technologies developed for oleaginous microalgae cultivation to improve their biomass content and lipid accumulation capacity were reviewed. The production of renewable, carbon neutral, bio-based or microalgae-based transport fuels are necessary for environmental protection and economic sustainability. Microalgae are a significant source of renewable biodiesel because of their ability to produce oils in the presence of sunlight more efficiently than that of crop oils. This review will provide the background to understanding the bottlenecks and the need for improvement in the cultivation or harvesting process for oleaginous microalgae.
A Typology-Based Approach for Assessing Qualities and Determinants of Adoption of Sustainable Water Use Technologies in Coping with Context Diversity: The Case of Mechanized Raised-Bed Technology in Egypt
Authors: Le Quang Bao , Dhehibi Boubaker
Published: September 2019

Mechanized raised-bed technology (MRBT) is recognized as an important measure to achieve higher crop productivity and water-use efficiency in intensive irrigated systems. Development efforts on spreading this technology require adequate understanding of the qualities and drivers of farmers’ adoption of MRBT. Research in agricultural innovation adoption has identified the importance of the socio-ecological context (SEC) that influences the livelihood of farmers adopting new technologies. This study introduces an agricultural livelihood systems (ALS) typology-based approach for guiding concrete analytical steps and statistical methods in evaluating the effects of system SEC diversity in two Egyptian governorates. We objectively classify a population of sampled farming households into a limited number of ALS types and use inferential statistics for the whole sampled population and individual ALS types to discover adoption drivers. Values added by the ALS approach confirm the widespread role of common determinants of MRBT adoption across ALS types, household groups subject to the effects MRBT, and show new causal effects. The presented advanced approach and empirical findings will be useful for enhancing targeting and out-scaling of MRBT practices toward achieving sustainable agricultural water uses at scale.

Published: September 2019

In this work, we numerically study a thermo-mechanical problem arising in poro-viscoelasticity with the type III thermal law. The thermomechanical model leads to a linear system of three coupled hyperbolic partial differential equations, and its weak formulation as three coupled parabolic linear variational equations. Then, using the finite element method and the implicit Euler scheme, for the spatial approximation and the discretization of the time derivatives, respectively, a fully discrete algorithm is introduced. A priori error estimates are proved, and the linear convergence is obtained under some suitable regularity conditions. Finally, some numerical results, involving one- and two-dimensional examples, are described, showing the accuracy of the algorithm and the dependence of the solution with respect to some constitutive parameters.

Published: September 2019

Legumes are amongst the most promising crops to satisfy the increasing demand for protein-rich food and feed. Today, however, their cultivation in Europe is low, while European agriculture faces a deficit of protein-rich feed, of which the largest part is met by imported soybean. It has been suggested that some legumes can at least partially substitute for soybean in different types of feed. Despite their benefits, legumes may also remain a significant concern to human and animal health, especially regarding grain contamination with Fusaria and their mycotoxins. In this study, we determined the species composition of Fusarium field isolates recovered from diseased grains of various legumes. Our results showed that Fusarium avenaceum was mainly responsible for grain deterioration of common vetch, faba bean, and blue lupine. Besides, we found that F. equiseti also appeared to be a major pathogen of common vetch. This study is the first ever to report common vetch as a host for F. tricinctum, F. equiseti, and F. graminearum sensu stricto. Our results indicate that the composition of toxigenic Fusaria associated with grains of legumes is different than that previously observed in cereal grains.

Published: September 2019

Approximately 70 species of Prorocentrum are known, of which around 30 species are associated with benthic habitats. Some produce okadaic acid (OA), dinophysistoxin (DTX) and their derivatives, which are involved in diarrhetic shellfish poisoning. In this study, we isolated and characterized Prorocentrum concavum and P. malayense from Broome in north Western Australia using light and scanning electron microscopy as well as molecular sequences of large subunit regions of ribosomal DNA, marking the first record of these species from Australian waters. The morphology of the motile cells of P. malayense was similar to P. concavum in the light microscopy, but differed by the smooth thecal surface, the pore pattern and the production of mucous stalk-like structures and a hyaline sheath around the non-motile cells. P. malayense could also be differentiated from other closely related species, P. leve and P. foraminosum, despite the similarity in thecal surface and pore pattern, by its platelet formula and morphologies. We tested the production of OA and DTXs from both species, but found that they did not produce detectable levels of these toxins in the given culturing conditions. This study aids in establishing more effective monitoring of potential harmful algal taxa in Australian waters for aquaculture and recreational purposes.
Risk Factors for Infectious Diseases in Urban Environments of Sub-Saharan Africa: A Systematic Review and Critical Appraisal of Evidence
Authors: Boyce Matthew R. , Katz Rebecca , Standley Claire J.
Published: September 2019

Our world is rapidly urbanizing. According to the United Nations, between 1990 and 2015, the percent of the world’s population living in urban areas grew from 43% to 54%. Estimates suggest that this trend will continue and that over 68% of the world’s population will call cities home by 2050, with the majority of urbanization occurring in African countries. This urbanization is already having a profound effect on global health and could significantly impact the epidemiology of infectious diseases. A better understanding of infectious disease risk factors specific to urban settings is needed to plan for and mitigate against future urban outbreaks. We conducted a systematic literature review of the Web of Science and PubMed databases to assess the risk factors for infectious diseases in the urban environments of sub-Saharan Africa. A search combining keywords associated with cities, migration, African countries, infectious disease, and risk were used to identify relevant studies. Original research and meta-analyses published between 2004 and 2019 investigating geographical and behavioral risk factors, changing disease distributions, or control programs were included in the study. The search yielded 3610 papers, and 106 met the criteria for inclusion in the analysis. Papers were categorized according to risk factors, geographic area, and study type. The papers covered 31 countries in sub-Saharan Africa with East Africa being the most represented sub-region. Malaria and HIV were the most frequent disease focuses of the studies. The results of this work can inform public health policy as it relates to capacity building and health systems strengthening in rapidly urbanizing areas, as well as highlight knowledge gaps that warrant additional research.

Published: September 2019

The elimination of rabies transmitted by Classical Rabies Virus (RABV) in the European Union (EU) is now in sight. Scientific advances have made it possible to develop oral vaccination for wildlife by incorporating rabies vaccines in baits for foxes. At the start of the 1980s, aerial distribution of vaccine baits was tested and found to be a promising tool. The EU identified rabies elimination as a priority, and provided considerable financial and technical resources to the infected EU Member States, allowing regular and large-scale rabies eradication programs based on aerial vaccination. The EU also provides support to non-EU countries in its eastern and south eastern borders. The key elements of the rabies eradication programs are oral rabies vaccination (ORV), quality control of vaccines and control of their distribution, rabies surveillance and monitoring of the vaccination effectiveness. EU Member States and non-EU countries with EU funded eradication programs counted on the technical support of the rabies subgroup of the Task Force for monitoring disease eradication and of the EU Reference Laboratory (EURL) for rabies. In 2018, eight rabies cases induced by classical rabies virus RABV (six in wild animals and two in domestic animals) were detected in three EU Member States, representing a sharp decrease compared to the situation in 2010, where there were more than 1500 cases in nine EU Member States. The goal is to reach zero cases in wildlife and domestic animals in the EU by 2020, a target that now seems achievable.
Utilising Group-Size and Home-Range Characteristics of Free-Roaming Dogs (FRD) to Guide Mass Vaccination Campaigns against Rabies in India
Authors: Tiwari Harish Kumar , Bruce Mieghan , O’Dea Mark , Robertson Ian D
Published: September 2019

Adequate vaccination coverage of free roaming dogs (FRD) against canine rabies is not achieved primarily due to difficulties in administering parenteral vaccinations to this population. One factor associated with this difficulty is the tendency of FRD to form groups, which increases their aggressive behavior, resulting in a significant risk of dog-bites for the vaccinators. This study investigated factors that influenced FRD forming groups and their home-ranges, using data obtained from photographic capture-recapture/sight-resight surveys conducted in rural Shirsuphal (584 sightings) and urban Panchkula (3208 sightings), India. In the rural site, older dogs (OR 0.5, 95% CI 0.2–0.9, p = 0.03) and FRD sighted within 20 m of garbage sites (OR 0.6, 95% CI 0.4–0.9, p = 0.02) were less likely to be in groups. The number of dogs sighted with an FRD decreased with increased resight-probability of that dog (β = −1.0, p < 0.001). The rural FRD with smaller home-ranges were more likely to be sighted alone (OR 2.3, 95% CI 1.0–95, p = 0.04) than those with larger home-ranges. In the urban site, females (OR 1.3, 95% CI 1.1–1.5, p = 0.002) and older dogs (OR 1.5, 95% CI 1.1–2.1, p = 0.07) were more likely to be found in groups, and groups of dogs were more likely to be seen within 20 m of garbage sites (OR 1.7, 95% CI 1.5–2.0, p < 0.001). The distribution of urban FRD sighted alone, in pairs, triads, and in packs of ≥4 dogs were not random in the administrative (p = 0.02), and the two industrial (p = 0.03 & 0.01) survey tracks of the urban site, implying stable groups. The resighting probability of a dog (β = 0.3, p < 0.0001) and presence of garbage within 20 m (β = 0.2, p < 0.0001) in the urban site increased the likelihood of sighting a FRD with other dogs. It is concluded that data on the resighting probability, presence of garbage points, and home-ranges can be utilised to guide the selection of parenteral or oral rabies vaccination to achieve a population vaccination coverage of 70% to break the transmission cycle of rabies virus in FRD in India.

Published: September 2019

Efficient design and management of water distribution networks is critical for conservation of water resources and minimization of both energy requirements and maintenance costs. Several computational routines have been proposed for the optimization of operational parameters that govern such networks. In particular, multi-objective evolutionary algorithms have proven to be useful both properly describing a network and optimizing its performance. Despite these computational advances, practical implementation of multi-objective optimization algorithms for water networks is an abstruse subject for researchers and engineers, particularly since efficient coupling between multi-objective algorithms and the hydraulic network model is required. Further, even if the coupling is successfully implemented, selecting the proper set of multi-objective algorithms for a given network, and addressing the quality of the obtained results (i.e., the approximate Pareto frontier) introduces additional complexities that further hinder the practical application of these algorithms. Here, we present an open-source project that couples the EPANET hydraulic network model with the jMetal framework for multi-objective optimization, allowing flexible implementation and comparison of different metaheuristic optimization algorithms through statistical quality assessment. Advantages of this project are discussed by comparing the performance of different multi-objective algorithms (i.e., NSGA-II, SPEA2, SMPSO) on case study water pump networks available in the literature.
Extending the Holding Time for Agricultural Water Testing EPA Method 1603 for Produce Growers
Authors: Bhullar Manreet Singh , Shaw Angela , Hannan Joseph , Andrews Smaranda
Published: September 2019

Agricultural water is a known vector for the transfer of foodborne pathogens onto fresh produce. Development of pre-harvest and post-harvest microbial profiles of agricultural water used by fresh produce growers, processors, and holdings is a requirement under the Food Safety Modernization Act Produce Safety Rule. One of the United States Environmental Protection Agency (US EPA) approved agricultural water testing methods is US EPA Method 1603, which requires no greater than a 6-h time frame between the collection of the water sample and initiation of analysis. This 6-h timeframe is unrealistic for many produce growers due to there being few laboratories certified to conduct testing and the geographic location of the farms. Agricultural water samples (n = 101) from well water and surface water were collected from 60 different farms to determine if holding samples for 24 h yielded significantly more generic Escherichia coli (E.coli) than 6 h using EPA 1603 method. A total of 32 samples were found contaminated with generic E. coli. Of these positive samples, surface water accounted for 87.5% of the samples (n = 28). There was no significant disparity between populations of generic E. coli at 6- and 24-h sample-test time interval (p > 0.05). These results provide evidence that the sample-test time interval can be extended to 24-h time, which makes quantitative generic E. coli testing for agricultural water as mandated by the FSMA Produce Safety Rule more accessible to growers.
Blue-Green Infrastructure for Sustainable Urban Stormwater Management—Lessons from Six Municipality-Led Pilot Projects in Beijing and Copenhagen
Authors: Liu Li , Fryd Ole , Zhang Shuhan
Published: September 2019

Managing stormwater on urban surfaces with blue-green infrastructure (BGI) is being increasingly adopted as an alternative to conventional pipe-based stormwater management in cities. BGI combats water problems and provides multiple benefits for cities, including improved livability and enhanced biodiversity. The paper examines six municipality-led pilot projects from Beijing and Copenhagen, through a review of documents, site observations and interviews with project managers. Beijing’s projects attempt to divert from a pipe-based approach but are dominated by less BGI-based solutions; they could benefit from more integration of multiple benefits with stormwater management. Copenhagen’s projects combine stormwater management with amenity improvement, but lack focus on stormwater utilization. Reviewed municipality-led pilot projects are shown to play an important role in both testing new solutions and upscaling them in the process of developing more sustainable cities. Key lessons are extracted and a simple guideline synthesized. This guideline suggests necessary considerations for a holistic solution that combines stormwater management and urban space improvements. Key lessons for sustainable solutions include defining a clear water technique priority, targeting both small and big rain events, strengthening ‘vertical design’ and providing multiple benefits. An integrated stormwater management and landscape design process is a prerequisite to the meaningful implementation of these solutions. Research and documentation integrated with pilot projects will help upscale the practice at city scale.

Published: September 2019

Dam building and reservoir operations alter the downstream hydrological regime, and as a result, affect the health of the river aquatic ecosystem, particularly for large-scale cascade reservoirs. This study investigated the impact of the Gezhouba Reservoir (GR) and the Three Gorges Reservoir (TGR) on the spawning conditions of two critical taxa, i.e., the endemic four major carps and the endangered Chinese sturgeon in the Yangtze River. We analyzed the flow, sediment, and thermal regime in these two taxa spawning seasons and compared their features between the predam and postdam periods. Our results revealed that the GR and the TGR had altered the frequency distributions of flow, sediment, and water temperature to different degrees, with the impact by the GR on the carps and Chinese sturgeon ranked as water temperature > flow, sediment > water temperature > flow, and the effect of the TGR on these two taxa were ordered as flow > water temperature, sediment > flow > water temperature. For the GR, the satisfying degree of the suitable flow and water temperature of the carps increased, whilst the suitable flow, sediment, and water temperature for the Chinese sturgeon decreased. These changes in TGR showed a significant ascending (descending) trend in the suitable flow (water temperature) for the carps, and a clear decreasing trend in the flow, sediment, and temperature for Chinese sturgeon. Both the TGR and the GR had negative impacts on the spawning of these two taxa in terms of the rising/falling flow characteristics.

Authors: den Boer Jacomien , Dieperink Carel , Mukhtarov Farhad
Published: September 2019

Although social learning is a key element of multilevel flood risk governance, it is hardly studied. This paper addresses this knowledge gap. The paper aims to identify enabling conditions for social learning in multilevel flood risks governance arrangements. We first conceptualize social learning and draw up a conceptual framework consisting of enabling conditions for social learning, using the literature on adaptive co-management, sustainable land and water management, and integrated flood risk management. Next, we apply this framework to analyze social learning in the context of the Dutch Room for the River program. Our interview results reveal that social learning about integrated flood protection measures took place at multiple levels. We found that a strong personal commitment to learning and mutual interpersonal trust in working groups are key conditions for successful social learning. Based on our analysis, we conclude with some recommendations for enhancing social learning processes in future flood protection programs.
Impacts of Climate Change and Human Activities on Runoff Variation of the Intensive Phosphate Mined Huangbaihe River Basin, China

Published: September 2019

Natural hydrological processes have been changed under the combined influences of climate change and intensive human activities in the Huangbaihe River Basin, where large-scale phosphate mining has been taking place. Therefore, evaluating the impact of climate change and intensive human activities on runoff variation and detecting the main driving factor leading to the variation are important for more efficient water resource management and more sustainable development of the regional economy. Despite numerous studies having been performed on this topic, little research focused on the impact of mining on runoff variation. The non-parametric Mann-Kendall (MK) trend test and accumulative anomaly methods were applied to identifying basic trends and change points of the hydro-meteorological elements over the period from 1978 to 2016. Then, the Soil Water and Assessment Tool (SWAT) and the Slope Changing Ratio of Accumulative Quantity (SCRAQ) were both used to quantify the contributions of climate change and anthropogenic activities on runoff variation. In this step, the runoff data were restored to their natural state before the construction of Xuanmiaoguan (XMG) dam. Due to the lack of locally observed evapotranspiration data, Global Land Evaporation Amsterdam Model and an empirical equation applied to obtain the evapotranspiration data. The results revealed that the change points are in 1985 and 2006. Therefore, the total period was divided into three periods, that is, the baseline period Ta (1978–1984), change period Tb (1985–2005) and change period Tc (2006–2016). Compared with the baseline period Ta, climate change dominates the runoff variation in the period Tb and is responsible for 60.5 and 74.4% of runoff variation, while human activities contribute the most to runoff variation for the period Tc (79.3 and 86.1%). Furthermore, an analysis of the underlying mechanism of underground phosphate mining indicates that mining can affect overland flow and baseflow simultaneously. This study can provide some information in determining the contributions of climate change and human activities in intensive phosphate mined basins and areas lack of evapotranspiration data.

Published: September 2019

The application of electrical platform for converter station in offshore wind farm is highly forward-looking and strategic. The offshore electrical platform is complicated in structure, bulky in volume, and expensive in cost. In addition, the built-in electrical equipment is very sensitive to the acceleration response. Therefore, it is very important to study the hydrodynamic response of the electrical platform exposed in the open sea. Based on the elastic similarity, Froude similarity, as well as the flexural-stiffness similarity of the cross-section, the hydroelastic similarity was derived to guide the model test of a 10,000-ton offshore electrical platform in wind, wave, and current. The hydrodynamic responses including strain and acceleration at key positions of the structure were obtained for different incident angles of external environmental loads. The experimental results showed the increase of water depth can cause more than 10 times increase of strain and acceleration response of the platform. The attack angle of external environmental loads had no definite relationship with strain response of the structure. Therefore, the most dangerous attack angle cannot be determined. The strain of the structure under the combined action of wind, wave, and flow was significantly larger than that under wave load only.

On the Use of Parametric Wind Models for Wind Wave Modeling under Tropical Cyclones
Authors: Ruiz-Salcines Pablo , Salles Paulo , Robles-Díaz Lucia , Díaz-Hernández Gabriel , Torres-Freyermuth Alec , Appendini Christian M.
Published: September 2019

Wave and wind forces from tropical cyclones are one of the main design parameters of coastal and offshore infrastructure in tropical areas. The estimation of ocean waves parameters in the design of structures in tropical areas is difficult due to the complexity of wind fields associated with tropical cyclones. The use of numerical wave models, forced with parametric wind fields, is a common practice within the climatic characterization of extreme events. However, there is currently no consensus on the selection of parametric models for wave prediction due to the lack of a rigorous assessment of different models. In this study, six well-known parametric wind models were tested, compared, and applied in the Gulf of Mexico and the Caribbean Sea. Therefore, the evaluation and comparison of the resulting wind and wave fields are presented, showing that a particular model may best represent a specific event, but, when dealing with a large number of events, the choice of a particular parametric wind model or a combination of them does not guarantee greater accuracy.

Le bilinguisme devient un phénomène universel et continu grâce à la mondialisation qui implique la communication et l’échange internationaux. Il est donc indispensable de nos jours, que chaque individu connaisse une 2ème voire 3ème langue / culture. C’est pourquoi notre recherche vise le public d’étudiant bilingue immigré de licence et de master FLE. L’objectif principal de notre étude est d’analyser l’effet de l’usage de la 2ème langue (le français) sur la production écrite. Afin de parvenir à notre objectif, nous avons utilisé les méthodes qualitatives et quantitatives. Dans le but de déterminer l’intensité d’usage des langues turque et française ainsi que le domaine d’utilisation du français, nous avons utilisé un questionnaire. Ensuite, nous avons proposé aux participants de rédiger deux textes différents, l’un dans le domaine personnel, l’autre éducationnel. Finalement, les données obtenues ont été soutenues avec les entretiens semi-dirigés. Selon les résultats, aucune relation n’a été constatée entre l’usage intense de la langue française et le niveau de réussite en compétence écrite. Cependant l’usage spécifique de la langue dans les domaines personel et éducationnel aboutit à de bons résultats dans ceux-ci. Ainsi, les résultats des entretiens indiquent que le public cible éprouve des difficultés en orthographe et en grammaire. Afin d’y remédier, les participants ont indiqué qu’ils devaient lire plus intensivement et qu’ils devaient retravailler la grammaire.

Geri dönüşümü yapılabilecek maddeleri ayırt eder.” kazanımına ne kadar ulaşabildiklerini belirlemektir. Bu amaç doğrultusunda nitel ve nicel araştırma yaklaşımlarının birlikte kullanıldığı karma desenden yararlanılmıştır. Araştırmanın katılımcılarını 2018-2019 eğitim öğretim yılının bahar döneminde orta sosyo-ekonomik çevreye sahip bir ilkokulun birinci sınıfına devam eden öğrenciler oluşturmuştur. Araştırmanın nicel verileri; öğrencilerin değerlendirme aracından elde ettikleri skorlara dayalı olarak toplanmıştır. Araştırmanın nitel boyutundaki veriler ise öğrencilerle gerçekleştirilen yarı yapılandırılmış görüşmeler aracılığıyla toplanmıştır. Araştırmada elde edilen sonuçlara göre; elma en çok doğru yere yerleştirilen, poşet ve bardak ise en az doğru yerleştirilen öğe olmuştur. Ayrıca öğrencilerin çöp kutusunu veya geri dönüşüm kutularından herhangi birini seçmelerinde değerlendirme aracındaki görsellerin durumu onların kararlarını etkilediği elde edilen bir başka bulgudur. Son olarak öğrenciler değerlendirme aracını rahatlıkla kullanmış ve bu süreçten keyif aldıkları ve ilgili kazanımı kısmen edindikleri görülmüştür.
Kršćanski Weltanschauung i etika kod Romana Guardinija
Authors: Dotolo Carmelo
Published: September 2019

Jedna od zasluga razmišljanja Romana Guardinija jest da je pridonio boljem ocrtavanju teološkog promišljanja dvadesetog stoljeća i njegova epistemološkog statusa, ponajprije u interdisciplinarnoj pozornosti i logici dijaloga. U tom smislu, hermeneutička figura Weltanschauunga čini se plodnom, sa zanimljivim razvojem: ona poziva teologiju da razmišlja o sebi i ponaša se kao intelektualni partner među ostalima, pokazujući teoretski identitet koji se može postaviti na granicu znanja koje u srcu ima razumijevanje otajstva stvarnog. Iz te perspektive religiozno iskustvo pridonosi drugačijem razumijevanju ljudskog stanja, otvarajući ga objavi kao nužnom uvjetu za pokretanje potrage za nekim važnim ključevima čitanja u tumačenju svijeta i povijesti. To donosi barem dvostruku posljedicu. Prva je tvrdnja o objavljujućoj strukturi stvarnosti u kojoj se religija pojavljuje kao poseban način nastanjivanja svijeta, u kojem se oblikuju pitanja i obzorja egzistencije. Druga je pokazatelj „kršćanske kulture“ kao radikalne i jedinstvene perspektive o čovjeku, svijetu, povijesti, koja na temelju uskrsnog događaja postaje proročanstvo smisla u sociokulturnim procesima.
Poimanje teologije u Erika Petersona
Authors: Raguž Ivica , Klem Dino
Published: September 2019

U radu su predstavljeni neki aspekti misli njemačkog teologa Erika Petersona o biti, preduvjetima i ulozi teologije. U prvome dijelu rada polazi se od Petersonova kritičkog stava spram dvojice suvremenika – Rudolfa Bultmanna i njegova shvaćanja teologije koja polazi od ljudske egzistencije te Karla Bartha i dijalektičke teologije. Iz Petersonove kritike dolazi se do njegova vlastitog shvaćanja teologije, pri čemu se posebno obrađuje pojam dogme, što čini drugi dio rada. Time se nastoji odrediti zašto taj pojam zauzima središnje mjesto u njegovu poimanju teologije i koje su njegove posljedice za istu.

Tandan kosong kelapa sawit (TKKS) merupakan limbah padat yang dihasilkan pabrik kelapa sawit. Pemanfaatan kelapa sawit masih belum optimal dilakukan, oleh karena itu pada penelitian ini dilakukan pemanfaatan TKKS sebagai bahan baku pembuatan kompos. Selain itu, pada penelitian ini juga dilakukan aplikasi pemberian pupuk kompos TKKS pada tanaman cabe dan jagung. Pembuatan pupuk kompos diawali dengan menyiapkan aktivator EM-4 dan mencampurkannya pada bahan berikut: pupuk kandang , dedak, air sumur, air kelapa, dan tandan kosong kelapa sawit (TKKS), diinkubasi pada kondisi aerob. Berdasarkan hasil pengamatan tekstur dan suhu pengomposan, serta hasil pengaplikasian terhadap tanaman cabe dan jagung, diketahui bahwa kompos C dengan komposisi a) Pupuk kandang 0,5 kg, b) Dedak 0,5 kg, c) Air sumur 2 liter, d) Air kelapa 0,1 liter, e) EM-4 0,1 liter, f) TKKS 10 kg adalah kompos terbaik. Uji sampel terhadap kompos C juga menunjukan bahwa kandungan P total (0,2725) dan N total (1,30) adalah lebih tinggi dari nilai SNI pupuk kompos. Pupuk kompos TKSS bersifat ramah lingkungan bisa menjadi alternatif solusi permasalahan limbah yang ada di perkebunan dan pabrik pengolahan sawit.

Petani karet di Kabupaten Tanah Laut pada umumnya untuk proses penggumpalan (koagulasi) lateks masih banyak menggunakan bahan yang tidak dianjurkan seperti tawas, pupuk TSP, dan lain-lain. Mengingat sifatnya yang berbahaya, maka perlu dicari bahan pengganti yang aman bagi lingkungan. Salah satu bahan penggumpal lateks yang aman dan murah salah satunya adalah asap cair. Untuk memproduksi asap cair yang efektif dan efisien diperlukan suatu alat yang disebut reaktor pirolisis. Pirolisis merupakan proses pemanasan suatu zat tanpa adanya oksigen sehingga terjadi penguraian komponen-komponen penyusun kayu keras. Istilah lain dari pirolisis adalah penguraian yang tidak teratur dari bahan-bahan yang disebabkan oleh adanya pemanasan tanpa berhubungan dengan udara luar. Penelitian ini memiliki tujuan untuk mendesain alat pirolisis pembuatan asap cair berbahan baku tempurung kelapa yang akan diaplikasikan sebagai pengental lateks. Alat ini terdiri dari tiga komponen utama yaitu ruang pirolisis, pendingin asap cair, dan ruang control panel. Asap cair dibuat dengan memvariasikan temperatur pirolisis yaitu 150oC, 175oC dan 200oC dengan lama waktu pirolisis 1 jam dan 2 jam, kemudian asap cair yang dihasilkan dianalisis rendemen dan pH. Aplikasi asap cair yang dihasilkan digunakan untuk koagulan lateks. Analisis terhadap karet yang dihasilkan dilakukan dengan menghitung kadar karet kering. Hasil penelitian menunjukkan bahwa waktu beku lateks paling cepat dan rendemen tertinggi ditunjukkan oleh asap cair yang dibuat pada kondisi temperatur 175oC dan waktu pirolisis 2 jam dengan rendemen 27,34%. Kadar karet kering tertinggi juga terjadi pada penggunaan asap cair kondisi temperature 175oC dan waktu pirolisis 2 jam sebagai koagulan dengan KKK sebesar 41,24%.
