Tendencias Mundiales en la Gestión de Recursos Hídricos: Desafíos para la Ingeniería del Agua
Authors: Restrepo Tarquino Inés
Published: May 2020

Los avances en el conocimiento han llevado a nuevas propuestas para la gestión de los recursos hídricos, como respuesta a la denominada “crisis del agua”, la cual es una de las mayores preocupaciones del planeta. La adecuada gestión de estos recursos forma además parte de las propuestas para alcanzar los Objetivos de Desarrollo del Milenio (ODM) de las Naciones Unidas, especialmente el objetivo de reducir la pobreza y el hambre que sufren buena parte de la población mundial. Así, el ser humano y el ambiente se convierten en el centro de las propuestas de gestión del agua, no sólo por su efecto sobre la salud sino por su influencia sobre el bienestar y el desarrollo de los pueblos. La ingeniería del agua debería entonces dar un vuelco de tal forma que la tecnología sea una respuesta a las necesidades sociales, ambientales y económicas de la sociedad, bajo criterios de eficiencia y sostenibilidad.

LA COMPLEMENTARIEDAD ENTRE EL MÉTODO DE ENSEÑANZA DE SINTAXIS TRADICIONAL E INVERSO EN 3º DE E.S.O.
Authors: Galera Fernández Francisco Javier
Published: May 2020

El presente trabajo analiza dos métodos de enseñanza de sintaxis aplicados en Educación Secundaria: la sintaxis tradicional y la sintaxis inversa. Del estudio de ambos métodos se deduce su complementariedad y su necesidad mutua a la hora de ponerlos en práctica. Así, el objetivo fundamental del trabajo es estudiar cómo se comportan los dos métodos en un aula de 3º E.S.O. y añadir un componente lúdico a su enseñanza que motive a los alumnos y los lleve hacia una mejora de los resultados. Además, para corroborar todo ello se recoge una muestra empírica en el Centro I.E.S. Rosa Navarro (Olula del Río, Almería) en 3º de E.S.O. Una vez analizados los datos, se proponen una serie de conclusiones que dejan patente el grado de complementariedad que puede existir entre ambos métodos de enseñanza. This document analyses two teaching syntax methods applied to Secondary Education: the traditional syntax and the inverse syntax. From the study of these two methodologies, their complementarity and mutual necessity are deduced when putting them into practise. In this way, the main objectives of this research are to study how these two methods work in a 3rd ESO class and to add a playful component to their learning processes that motivate the students so they can get an improvement on their results. Also, in order to confirm all these, an empirical sample is collected from the Secondary Education High School called Rosa Navarro (Olula del Río, Almería) in the 3rd year of ESO. Once the data are analysed, some conclusions are proposed in order to establish the degree of complementarity existing between the two mentioned teaching methods.

INTELIGENCIA EMOCIONAL, ADICCIÓN AL SMARTPHONE Y MALESTAR PSICOLÓGICO COMO PREDICTORES DE LA NOMOFOBIA EN ADOLESCENTES
Authors: Díaz Miranda Neryelith , Extremera Pacheco Natalio
Published: May 2020

El objetivo de la presente investigación es analizar la relación entre las variables adicción al smartphone, inteligencia emocional, y malestar psicológico con los niveles de nomofobia, así como examinar el grado de dichas variables para predecir varianza explicativa de esta fobia comportamental hacia los smartphones. Se pasaron diferentes escalas validadas para evaluar inteligencia emocional, adicción al smartphone, malestar psicológico y nomofobia en una muestra de 312 adolescentes de entre 14 y 20 años, de Málaga e Ibiza. Los resultados indicaron que existen unos niveles moderados de nomofobia entre los adolescentes. Los análisis de regresión demostraron que dos dimensiones de la inteligencia emocional (percepción interpersonal y uso de las emociones), la ansiedad y la adicción al smartphone explicaban significativamente varianza de los niveles de nomofobia. Nuestros hallazgos sugieren que los futuros programas relacionados con la prevención de la nomofobia, deberían poner su atención a los niveles de habilidades emocionales, salud mental positiva y estrategias preventivas de uso razonable y no problemático del smartphone.

Published: May 2020

Asphalt profile control is an effective method, which can further improve oil recovery of reservoir polymer flooded, it has a lot of advantages including high strength profile control, seal strata formation efficiency, low cost and no pollution, but there has not a perfect evaluation system for its development mode. The effect of different concentration, injection rate, radius of profile control, the timing of profile and segment combination way on the oil displacement effect of the asphalt profile control were researched using numerical simulation method on actual typical well area in Daqing oilfield, and the mechanism of asphalt profile control was studied in detail. According to the results of laboratory test, the largest Enhanced Oil Recovery (EOR) of asphalt was obtained at injection concentration 4000 mg/L, and the best combination was “high–low–high” concentration slug mode. According to the results of numerical simulation, the best concentration, injection rate, radius of profile control and injection timing were 4000 mg/L, 0.15 PV/a (Pore Volume [PV], m3), 1/2 of well spacing and 96% water cut in single slug of asphalt injection system, when the injection condition was multiple slug, the “high–low–high” slug combination mode was the best injection mode. These results could provide effective development basis for asphalt profile control after polymer flooding in thick oil layers.

Authors: Perdał Robert , Churski Paweł , Herodowicz Tomasz , Konecka-Szydłowska Barbara
Published: May 2020

The process of socio-economic development is subject to changes resulting from the interaction of contemporary socio-economic megatrends which modify the influence of development factors and affect the polarisation of development in space. The measures to date, adopted as part of the cohesion policy and intended to decrease the differences, have not produced the desired results. This leads to the search for new solutions which include place-based intervention. Here a special role is played by the largest cities performing the function of development poles. They can positively affect the development of the surrounding area. The work aims to identify the importance of cities in terms of socio-economic inequalities in Poland. The analysis is carried out at the local level and covers the years 2004-2016. The research includes three stages. What is discussed in the first is the role of cities as development poles. The second presents an analysis and classification of spatial differences in the level and dynamics of the development of the largest cities. The third stage determines the influence of these cities on the surroundings.
Financing of Integrated Territorial Investments on the example of Kielce Functional Area
Authors: Pietrowski Wojciech
Published: May 2020

The level of spending of funds under KIT's ITI is varied depending on the fund. The level of contracting of funds is higher under the ERDF, while in the case of their certification there is an advantage of the ESF. The difference between the value of contracted and certified funds is evident. Financing projects from structural funds on average exceeds 80% of the project value. The implementation of the instrument proceeds correctly from the point of view of spending the funds. Analysis of the contracting of funds in individual years indicates a delay in the implementation of programs, which is not an exception in the entire ROP of the SV 2014-2020. The author deals with the issue of financing ITI in the EU perspective 2014-2020.

Authors: Zufall Alina G , Li Rung-chi , Zlotoff Barrett J , Lawrence Monica G , Flowers Richard H
Published: May 2020

Eosinophilic annular erythema (EAE) is a rare eosinophilic dermatosis with few documented cases in the literature. It is considered either a distinct entity or subtype of Well’s syndrome (eosinophilic cellulitis), but EAE, in contrast to Well’s syndrome, is characterized by a chronic course and resistance to treatment. Therapies with reported efficacy include anti-malarial medications, suplatast tosilate, and dapsone. We report the first adult case of EAE to respond to dupilumab, an IL-4 receptor antagonist, which targets the type 2 inflammatory response associated with tissue eosinophilia.

Authors: Litchman Graham H , Prado Giselle , Teplitz Rebeca W , Rigel Darrell
Published: May 2020

To decrease morbidity and mortality from melanoma, it is imperative to identify patients who are at high risk for developing widespread disease. Gene expression profiling (GEP) technology may impact melanoma management as physicians are better equipped to measure prognosis. Many different GEP signatures have been investigated. We searched Pubmed, Cochrane CENTRAL, and Embase for studies on GEP in primary melanoma prognosis and assessed GEP signatures for prognostic and analytic validity and clinical impact. The relationship between GEP and survival was measured using hazard ratios (HR) and odds ratios (OR). We found twenty-nine articles comprising 9 gene signatures meeting inclusion criteria and conducted a meta-analysis on 6 studies on a 31-gene signature. High-risk GEP status was associated with poorer recurrence-free survival (HR=7.22; 95% CI, 4.75-10.98), distant metastasis-free survival (HR=6.62; 95% CI, 4.91-8.91), and overall survival (HR=7.06; 95% CI, 4.44-11.22); as well as sentinel lymph node biopsy positivity (OR=2.99; 95% CI, 2.15-4.15). With recent improvements in treating advanced melanoma, accurately assessing prognosis is important. This study has clinical implications for melanoma patients who may benefit from prognostic testing. These results may be useful to clinicians when ordering GEP testing and help them make better management decisions.
Safe use of Interleukin-17 Inhibitors for Psoriasis and Psoriatic Arthritis in Two Patients with a History of Lymphoproliferative Disease
Authors: Sansone Stephen , Amir Yasmin , Lebwohl Mark
Published: May 2020

Psoriasis and psoriatic arthritis are chronic, inflammatory, immune-mediated diseases that affect the skin and joints, respectively. The older systemic agents that have been used to treat these conditions are associated with many side effects, including an increased risk of malignancies, specifically lymphoma. In the last few years, there has been a wave of development of novel systemic biologic therapies to target psoriasis and psoriatic arthritis. While long-term safety data is lacking, the newer therapies targeting interleukins 12, 23, and 17 reveal a much more favorable side effect profile, specifically with regards to lymphoma. Here we report two cases of patients with psoriasis and psoriatic arthritis who had histories of lymphoma, both successfully treated with an interleukin-17 inhibitor without any recurrence or worsening of lymphoproliferative disease.
NIC-CAGE: An Open-Source Software Package for Predicting Optimal Control Fields in Photo-Excited Chemical Systems
Authors: Raza Akber , Hong Chengkuan , Wang Xian , Kumar Anshuman , Shelton Christian , Wong Bryan
Published: May 2020

We present an open-source software package, NIC-CAGE (Novel Implementation of Constrained Calculations for Automated Generation of Excitations), for predicting quantum optimal control fields in photo-excited chemical systems. Our approach utilizes newly derived analytic gradients for maximizing the transition probability (based on a norm-conserving Crank-Nicolson propagation scheme) for driving a system from a known initial quantum state to another desired state. The NIC-CAGE code is written in the MATLAB and Python programming environments to aid in its readability and general accessibility to both users and practitioners. Throughout this work, we provide several examples and outputs on a variety of different potentials, propagation times, and user-defined parameters to demonstrate the robustness of the NIC-CAGE software package. As such, the use of this predictive tool by both experimentalists and theorists could lead to further advances in both understanding and controlling the dynamics of photo-excited systems.
A Tunable 3D Printed Microfluidic Resistive Pulse Sensor for the Characterisation of Algae and Microplastics
Authors: Platt Mark , Hunsicker Eugenie , Pollard Marcus
Published: May 2020

Technologies that can detect and characterise particulates in liquids have applications in health, food and environmental monitoring. Here we present a low-cost and high-throughput multiuse counter that classifies a particle’s size, concentration, porosity and shape. Using an additive manufacturing process, we have assembled a reusable flow resistive pulse sensor. The device remains stable for several days with repeat measurements. We demonstrate its use for characterising algae with spherical and rod structures as well as microplastics shed from teabags. We present a methodology that results in a specific signal for microplastics, namely a conductive pulse, in contrast to particles with smooth surfaces such as calibration particles or algae, allowing the presence of microplastics to be easily confirmed and quantified. In addition, the shape of the signal and particle are correlated, giving an extra physical property to characterise suspended particulates. The technology can rapidly screen volumes of liquid, 1 mL/ min, for the presence of microplastics and algae.
Photocatalyst Z-Scheme System Composed of a Linear Conjugated Polymer and BiVO4 for Overall Water Splitting Under Visible Light

Published: May 2020

Linear conjugated polymers have potential as photocatalysts for hydrogen production from water but so far, most studies have involved non-scalable sacrificial reagents. Z-schemes comprising more than one semiconductor are a potential solution, but it is challenging to design these systems because multiple components must work together synergistically. Here, we show that a conjugated polymer photocatalyst for proton reduction can be coupled in a Z-scheme with an inorganic water oxidation photocatalyst to promote overall water splitting without any sacrificial reagents. First, a promising combination of an organic catalyst, an inorganic catalyst, and a redox mediator was identified by using high-throughput screening of a library of components. A Z-scheme system composed of P10 (homopolymer of dibenzo[b,d]thiophene sulfone)-Fe2+/Fe3+-BiVO4 was then constructed for overall water splitting under visible light irradiation. Transient absorption spectroscopy was used to assign timescales to the various steps in the photocatalytic process. While the overall solar-to-hydrogen efficiency of this first example is low, it provides proof of concept for other hybrid organic-inorganic Z-scheme architectures in the future.
A New Approach to Probe the Degradation of Fuel Catalysts Under Realistic Conditions: Combining Tests in a Gas Diffusion Electrode Setup with Small Angle X-Ray Scattering

Published: May 2020

A new approach for efficiently investigating the degradation of fuel cell catalysts under realistic conditions is presented combining accelerated stress tests (ASTs) in a gas diffusion electrode (GDE) setup with small angle X-ray scattering (SAXS). GDE setups were recently introduced as a novel testing tool combining the advantages of classical electrochemical cells with a three-electrode setup and membrane electrode assemblies (MEAs). SAXS characterization of the catalyst layer enables an evaluation of the particle size distribution of the catalyst and its changes upon applying an AST. The straight-forward approach not only enables stability testing of fuel cell catalysts in a comparative and reproducible manner, it also allows mechanistic insights into the degradation mechanism. In contrast to standard rotating disk electrode measurements or identical location microscopy, typical metal loadings for proton exchange membrane fuel cells (PEMFCs), i.e. 0.2 mgPt cm-2geo, are applied in the GDE and the degradation of the overall (whole) catalyst layer is probed. For the first time, realistic degradation tests can be performed comparing a set of catalysts with several repeats within reasonable time. It is demonstrated that independent of the initial particle size in the pristine catalyst, for ASTs simulating load cycle conditions in a PEMFC, all catalysts degrade to a more or less identical particle size distribution. The presented new approach will help to pave the way to develop improved PEMFC catalysts.
COVID-19 Repurposed Therapeutics Targeting the Viral Protease and Spike-protein:ACE2 Interface using MD-based Pharmacophore and Consensus Virtual Screening
Authors: Garabato Brady , Falchi Federico , Cavalli Andrea
Published: May 2020

Molecular dynamics (MD) and enhanced sampling MD was performed for 100 ns on the biological assembly of the COVID-19 protease (6LU7), and a template of the COVID-19 S-protein:ACE2 receptor interface (99.88% coverage of 6M0J; model03, swissmodel). Apo-site pharmacophores of the resulting structural clusters were used to mine the FDA database (8700 compounds), and a multi-target library was developed from MD-based hits in high affinity sites across 100 ns. Consensus hits from high throughput docking in crystal structures 5R82, 6LU7 and 6Y2F (protease), and 6VW1 (S-protein:ACE2) were also added, and the resulting libraries were re-docked into MD sites to collect potential COVID-19 re-purposed therapeutics by estimated binding energies.
Reconsidering XPS Quantification of Substitution Levels of Monolayers on Unoxidized Silicon Surfaces
Authors: Hu Minjia , Luber Erik , Buriak Jillian
Published: May 2020

In this preprint, we reevaluate the use of X-ray photoelectron spectroscopy (XPS) to determine substitution levels of reactions on non-oxidized silicon surfaces. XPS is the most commonly used method to determine the yields of reactions on surfaces. We go back to the most basic assumptions, and work through the calculations to provide a revised set of calculations that take into account (i) possible adventitious hydrocarbon contamination, (ii) the effect of choosing a different silicon crystal face [Si(100) versus Si(111)], and (iii) the utility of choosing a small heteroatom tag to enable a more accurate measure of substitution levels. We provide a simple algorithm and summary of the equations one can use to make it easy for the reader/researcher.
In Search for Effective and Safe Drugs Against SARS-CoV-2: Part III] the Electronic Factors of Remdesivir and the Naturally Extracted Aspirochlorine Drugs
Authors: Abdel-Mottaleb M. Sabry , Abdel-Mottaleb Yousra
Published: May 2020

This report is associated with an ongoing coronavirus outbreak. We selected Remdesivir (used in the treatment of Ebola) and Aspirochlorine (a natural product found in Aspergillus oryzae), and their binding to specific peptide sequences of the coronavirus S-protein: ACE2 interface-drug binding adduct were calculated. The stable intermolecular adducts between the chosen drug molecules with the S protein and ACE2 result in limited host-virus interactions. The electrophilicity and nucleophilicity indices of the drugs showed that both drugs act as electron sinks to shield ACE2 from interacting with the S protein. Aspirochlorine acts as an electron acceptor (electrophile) toward both individual targets, the ACE2, and S proteins (nucleophiles). Aspirochlorine electronically shields ACE2 from the interaction with S protein by sinking the electronic charge of the S protein. The electrophilicity and nucleophilicity parameters of Remdesivir were higher than those of ACE2, and both molecules were bound via hydrogen bonding intermolecular interactions without intermolecular electron transfer. Remdesivir also shields ACE2 from the S protein. The results obtained strongly suggest the beneficial use of both drugs. The results reported indicate that the association of remdesivir with the target proteins was exothermic, while it was endothermic in the case of Aspirochlorine. Both drugs offer protection and/or treatment against the coronavirus S-protein COVID-19.

Published: May 2020

Objective of the study: The aim of the article was to analyze the intellectual structure of publications on slavery within the scope of the Administration. To achieve this objective, the following research questions were proposed: What is the intellectual structure of recent publications on slavery in the business research area? How is the past of slavery remembered (or forgotten) in this century’s researches on business research area?Methodology/approach: We used the quantitative method of scientific mapping that combines bibliometrics and graphic representation. In this process, we extracted publications from the Scopus database and, then, grouped the references using the Bibexcel software. To identify the subgroups and create the visualization map, we used VOSviewer.Originality/Relevance: Slavery is generally considered to be the dark side of business practices, and for this reason, it is a topic that is still little explored in management research. The relevance of this study is to systematize the academic production of this sensitive topic and to offer scholars and practitioners in the area a detailed analysis of the theoretical foundation of studies on slavery.Main results: Results indicate that the intellectual structure of studies related to slavery can be grouped into nine pillars that cover several themes, such as heritage tourism, Critical Accounting, Management History and the perpetuation of the legacy of slavery in the globalized world.Theoretical/methodological contributions (mandatory): Analyzing the repressed memory of slavery in the context of management is necessary and a great opportunity for future research. It is undeniable that slavery is a part of History that cannot be overlooked and this study explores this latent gap in Management studies.
Schulz na scenie
Authors: Owczarski Wojciech
Published: May 2020

The aim of this paper is to answer the question why theatrical performances based on the literary works of Bruno Schulz usually turn out disappointing. It was first posed by Jerzy Jarzębski 25 years ago. The author of the present paper discusses Jarzębski’s theses and proposes his own explanation. He disagrees with a claim that Schulz’s fiction is “unstageable” by nature. In the era of post-dramatic theatre, the idea of “unstageability” is evidently anachronistic. Therefore, the author demonstrates that there must be something wrong in the theater directors’ approaches to Schulz and his works. An analysis of several performances from the recent decade – directed by Petr Boháč, Robert Drobniuch, Konrad Dworakowski, Edyta Janusz-Ehrlich, Tomasz Kajdański, Jacek Krawczyk, Leszek Mądzik, Jan Szurmiej, Piotr Tomaszuk, Julia Wernio, Ingmar Villqist and Rudolf Zioło – leads to a conclusion that contemporary artists who deal with Schulz are unable to look at him from a distance and free themselves from his influence. They are simply too passive to create an autonomous theatrical vision in which Schulz’s literary world would be only a component and not the dominant substance. For this reason, their theatrical adaptations remain unsuccessful. In Polish theater there was only one artist who became a real partner for Schulz, strong enough to face his genius –Tadeusz Kantor. In his Dead Class (1975), Kantor managed to “utilize” the poetics of Schulz’s stories to create his own, original, and totally independent narrative. Since that time, each director who wants to stage Schulz’s literary works has had to struggle not only with the author of The Cinnamon Shops, but also with the leader of the Theater of Death. And this is, indeed, a very difficult task.
Portret nauczyciela. Jak uczniowie odmalowali Brunona Schulza?
Authors: Warska Katarzyna
Published: May 2020

Bruno Schulz used to portray his students. They were usually glad for it, although some claimed that Schulz at times crossed the comfort limit of female students. After many years, students portrayed him in their testimonies in which they tried to remember what he was like, and their perspective was different from that of Schulz’s friends. Students always remain lower in the school hierarchy and usually they cannot get to know their teacher very well. Thus, they have to rely on what they observed during lessons or outside of school. Corporeality played an important role in students’ stories, simply because they had visual access to it: Schulz appeared in class in his bodily form. As a teacher, he used his body to work – he spoke, drew, walked, etc. He played with his body and was observed as a central figure in the classroom, playing his role of an authority before an audience. Consequently, students drew conclusions about his mental traits in reference to physical ones. Generally, the teacher’s body should be asexual, sterile, aesthetically pleasing, and reliable. Therefore, Schulz’s body was not entirely his own since it had to fit his social role, which it did not always do. Because Schulz’s corporeality was quite uncommon, students talked about it and then Schulz specialists asked their professional questions. Students described in detail his figure, gait, face, look, hands, clothes, voice, and sexuality. The essay is an attempt to collect all the relevant texts that address the topic. It proves that especially corporeality impacted how Schulz was perceived as a teacher and a human being. Students saw him either as rather withdrawn and stressed, or as a strong magnetic personality. It is hard to judge the truth value of their opinions – probably they tell us little about the real Schulz. However, dozens of statements by Schulz’s students that refer to his corporality greatly enhance his picture known from photos. A gender perspective makes the problem even more interesting, as we can see a difference between the memories of women and men: the former seem to resemble Schulz’s drawings and portraits of female sitters, while the latter his portraits of the male ones. Unfortunately, we have only a few female testimonies since Schulz taught mainly in a school for boys.
„Tak bliscy mi, jak sam sobie jestem bliski”. Jachimowicz o Schulzu i borysławskim „zagłębiu poetyckim”
Authors: Rosiek Stanisław

The paper is an extended comment on Marian Jachimowicz’s “Reminiscence of Bruno Schulz.” On the basis of ample unpublished archive materials, the author reconstructs Jachimowicz’s biography, paying the most attention to the period of 1938–1942, when Jachimowicz as an aspiring man of letters had close friendly contacts with Schulz as well as other artists and writers of the Drogobych and Borysław region, known as the “Borysław Poetry Zone” (Marek Zwillich, Anna Płockier, Henryk Wiciński, Juliusz Wit, Artur Rzeczyca, and others). It turns out that his relationship with Schulz was a formative literary experience for the young poet. As he admits, it was thanks to the access to Schulz’s library and his recommendations, that he came across the books by poets who became important for his own development. Meeting Schulz was also important for another reason: he was the first “great artist” whom Jachimowicz met in person, knowing his literary works – Cinnamon Shops and A Sanatorium under the Sign of the Hourglass – and appreciating them highly. Jachimowicz’s attitude to Schulz was ambiguous, and this is what the present paper is mainly about. Starting with an analysis of an unpublished “source reminiscence” of 1948, the author approaches its subsequent versions published in journals (Twórczość, 1958 and Poezja, 1966). It was characteristic for Jachimowicz that his imagination and memory, fixed upon Schulz for several decades, pictured the Drogobych writer as “approaching.” Particularly in the first version of his text, Jachimowicz describes Schulz’s physique, doing it in a shockingly brutal, even abjectal, way. On the other hand, his essays demonstrate a more and more intense tone of mourning. The world of Drogobych and Borysław, to which both Jachimowicz and Schulz belonged before the war, appears in them as an irrevocably lost Arcadia, the only reality where the former did not feel all alone.

The term 'Big Data' portrays inventive methods and advances to catch, store, disseminate, oversee and break down petabyte-or bigger estimated sets of data with high-speed & diverted structures. Enormous information can be organized, non-structured or half-organized, bringing about inadequacy of routine information administration techniques. Information is produced from different distinctive sources and can touch base in the framework at different rates. With a specific end goal to handle this lot of information in an economical and proficient way, parallelism is utilized. Big Data is information whose scale, differences, and unpredictability require new engineering, methods, calculations, and investigation to oversee it and concentrate esteem and concealed learning from it. Hadoop is the center stage for organizing Big Data, and takes care of the issue of making it valuable for examination purposes. Hadoop is an open source programming venture that empowers the dispersed handling of huge information sets crosswise over bunches of ware servers. It is intended to scale up from a solitary server to a huge number of machines, with a high level of adaptation to non-critical failure.

Parthenium hysterophorus is an annual herbaceous plant native to tropical America; and an invasive plant in Africa causing distressing effects on natural flora. This study investigated the effects of P. hysterophorus on the composition and diversity of native herbaceous plant species in Simanjiro rangeland, Tanzania. Plant species count data were collected from 60 (1m2) quadrats. Using generalized linear models (GLM), the abundance of P. hysterophorus was regressed against the abundance and diversity of the native herbaceous plants. Also, Jaccard’s similarity index was used to compare species composition. Results showed that there were 14 herbaceous plant species belonging to 13 genera and 10 families in the study area. Parthenium hysterophorus was the most dominant species recorded. The abundance of P. hysterophorus has a substantial negative effect on the abundance and diversity of other herbaceous plant species. Moreover, Jaccard’s similarity index showed a slightly significant difference between the infested and non-infested areas. This finding suggests that P. hysterophorus has a substantial potential threat on other herbaceous flora which are sources of food and nutrients to livestock and wild animals in the area. Thus, integrated management strategies are required to control the weed from spreading to other nearby rangelands.

Kawasan konservasi perairan (KKP) berfungsi untuk mengelola sumber daya perikanan dan keanekaragaman hayati laut agar dapat dimanfaatkan secara berkelanjutan. Kondisi ikan karang merupakan salah satu bioindikator untuk mengukur dampak pengelolaan KKP. Tujuan dari penelitian ini adalah untuk melihat dampak pembentukan KKP Daerah (KKPD) Pulau Ay dan Pulau Rhun terhadap sumber daya perikanan karang di Kepulauan Banda, Maluku, Indonesia. Metode yang digunakan untuk pengumpulan data yaitu Underwater Visual Census (UVC) dan Fish Length Estimation dengan bantuan peralatan SCUBA. Analisis data dilakukan dengan membandingkan data sekunder dan data primer yang meliputi kelimpahan, biomassa, status tropik dan komposisi ukuran ikan besar dan ikan kecil dari 10 famili ikan target dan ekonomis penting sebelum dan sesudah Pulau Ay dan Pulau Rhun dicadangkan sebagai KKP. Hasil penelitian menunjukan bahwa kelimpahan dan biomassa ikan karang secara temporal berfluktuasi sebelum dan sesudah Pulau Ay dan Pulau Rhun dicadangkan sebagai KKP, namun masih dalam kondisi melimpah dan tinggi. Status tropik dan komposisi ukuran ikan karang berubah-ubah sebelum dan sesudah pencadangan KKP, namun masih dalam kondisi seimbang antar kelompok tropik, ikan besar dan ikan kecil. Kesimpulan penelitian ini adalah pencadangan KKPD memberikan dampak positif terhadap sumber daya ikan karang di Pulau Ay dan Pulau Rhun.

Keperluan data dan informasi tentang habitat bentik sangat diperlukan untuk menjaga dan melestarikan ekosistem yang ada di perairan. Rusaknya habitat bentik dapat terjadi karena adanya aktifitas antropogenik dan bencana alam yang akan berimbas pada biota dan ekosistem yang ada disekitarnya, oleh karena itu untuk mengetahui dan memantau kondisi perairan dan habitat perairan dangkal perlu dilakukannya pemetaan. Penelitian ini bertujuan untuk menganalisis perubahan habitat dasar perairan laut dangkal di Karang Lebar, Kepulauan Seribu. Penelitian ini memanfaatkan citra multispektral resolusi tinggi QuickBird 2008 dan WordView-2 2018 untuk mendeteksi perubahan geospasial habitat bentik. Klasifikasi citra multispektral dilakukan dengan penerapan algoritma SVM (Support Vector Machine) dan transformasi DII (Depth Invariant Index) pada kedua citra yang digunakan. Jumlah kelas habitat bentik yang dihasilkan adalah sebanyak lima kelas yaitu terumbu karang, karang mati, padang lamun, pasir, dan rubble. Hasil analisis menunjukkan akurasi keseluruhan 58,18% dan 70,9% pada penerapan klasifikasi dengan input band multispektral masing-masing untuk citra 2008 dan 2018, serta 60% dan 80% pada hasil transformasi DII masing masing untuk citra 2008 dan 2018. Perubahan kelas rubble di tahun 2008 menjadi kelas pasir tahun 2018 merupakan yang paling besar luasannya dibandingkan dengan perubahan pada kelas lainnya, yaitu 81,46 ha.

Keanekaragaman dan kelimpahan ikan di perairan sangat tergantung dari kelimpahan fitoplankton sebagai makanannya, sedangkan kelimpahan fitoplankton tergantung kondisi kualitas perairan. Sebagai upaya mengetahui hubungan tersebut maka dilakukan penelitian ini yang bertujuan menganalisis hubungan kelimpahan fitoplankton, konsentrasi klorofil-a dan kualitas perairan. Penelitian ini dilakukan di perairan pesisir Sungsang, Sumatera Selatan dari Bulan Juli sampai Agustus 2017. Pengambilan sampel dilakukan dengan metode purposive sampling. Hasil penelitian menunjukkan bahwa kecerahan berkisar antara 6,3-45,5%, kekeruhan 2-4 NTU, suhu 29,6-30,8oC, pH 6,0-7,7, salinitas 0-16 ppt, DO 5,33-6,50 mg/L, BOD 0,4-3,6 mg/L, amonia 0,1-0,32 mg/L, fosfat 0,01-216 mg/L, nitrat 0,006-2,96 mg/L, klorofil-a 1,68-20,6 mg/m3 kelimpahan fitoplankton berkisar (96-240) mg/L. Terdapat hubungan positif antara konsentrasi klorofil-a dengan fitoplankton, fosfat, nitrat, DO, BOD5, secara berturut-turut sebesar 95,5%, 91%, 76,6%, 82,2%, -63%. Semakin tinggi konsentrasi fosfat dan nitrat makin tinggi pula konsentrasi klorofil-a, dan semakin tinggi konsentrasi klorofil-a menyebabkan konsentrasi oksigen terlarut semakin tinggi. Semakin tinggi BOD5 dan amonia maka konsentrasi klorofil-a makin rendah.
