De rechten van de verdediging in de context van omvangrijke datasets en geavanceerde zoekmachines in strafzaken: een suggestie voor uitbreiding
Strafzaken draaien steeds meer om omvangrijke datasets die bestaan uit digitaal bewijs en geavanceerde technologische zoekinstrumenten zoals Hansken, een big data forensisch instrument. In deze context hebben advocaten en wetenschappers al aangevoerd dat geavanceerde zoekmachines de positie van het Openbaar Ministerie aanzienlijk versterken ten koste van de verdediging, die over het algemeen geen toegang heeft tot deze instrumenten. Met als gevolg dat de verdediging weinig invloed heeft op wat in een strafzaak als relevante informatie geldt en nauwelijks mogelijkheden geeft om ontlastend bewijs te vinden en de betrouwbaarheid van digitaal bewijs te toetsen. Dit leidt vervolgens tot een aanzienlijke machts- en kennisasymmetrie. Het beginsel van equality of arms in de zin van art. 6 van het Europees Verdrag voor de Rechten van de Mens biedt een goede basis voor de ontwikkeling van nieuwe of uitgebreidere rechten van de verdediging die nodig zijn in het digitale tijdperk. In dit artikel bespreek ik de bestaande rechten van de verdediging en bied ik suggesties voor een verdere uitbreiding van de rechten ten aanzien van omvangrijke datasets en geavanceerde zoekmachines in strafzaken. Deze suggesties kunnen ook worden gebruikt in het kader van de modernisering van het Nederlandse strafprocesrecht.

Privacy, cryptovaluta en compliance
Het witwasprobleem van cryptovaluta lijkt te zijn verschoven naar de niet gereguleerde markt. De strafrechtelijke jurisprudentie laat zien dat de handel in bitcoins geen vrijplaats is waar witwasnormen niet zouden gelden maar biedt vooralsnog geen inzicht in de rol van anonieme privacy coins. Wordt het tijd om de witwastypologieën aan te passen?
Coefficient Estimates for Bi-univalent Functions Defined By (P, Q) Analogue of the Salagean Differential Operator Related to the Chebyshev Polynomials
Authors: Panigrahi Trailokya , Mohapatra Susanta Kumar 
Published: May 2021

In the present investigation we use the Jackson (p,q)-differential operator to introduce the extended Salagean operator denoted by Rkp,q. Certain bi-univalent function classes based on operator Rkp,q related to the Chebyshev polynomials are introduced. First, two coefficient bounds and Fekete-Szego inequalities for the function classes are established. A number of corollaries are developed by varying parameters involved.

Published: May 2021

Esta pesquisa teve como objetivo analisar o processo histórico de ocupação e povoamento da cidade de Jequié-BA. O estudo apresenta significativa importância, haja vista que os resultados elucidam o processo de ocupação, delimitação, transformação e urbanização da cidade. Diante disso, poderá subsidiar possíveis estudos à comunidade local, científica e escolar. Na consecução do trabalho realizaram-se pesquisas de campo e elaboração de mapas, bem como análises das obras de Santos (1957) e Araújo (1997) que subsidiaram os estudos. Os resultados comprovam que a ocupação, povoamento e formação urbana de Jequié, têm em seu arcabouço histórico disputas conflituosas entre os colonizadores e os indígenas na conquista do território e na busca por pedras preciosas. Ainda, verificou-se, que as terras onde se localiza a cidade, estiveram, desde o período colonial numa zona de confluência de muitas estradas, o que facilitou a passagem e parada dos tropeiros e fluxo de muitas pessoas no processo de vendas e trocas de mercadorias. Como as terras jequieenses estão em área de transição entre a zona da mata e a caatinga (onde se encontra a maior parte do município) as áreas próximas dos rios das Contas e Jequiezinho foram atrativos para o processo inicial de ocupação e povoamento. Comprovou-se, ainda, que Jequié, atualmente, se mantém no competitivo ramo econômico baiano nos setores de educação, comércio, serviços e saúde, de forma que atende aos 16 municípios da microrregião Médio Rio das Contas e, indiretamente, sustenta, também, sua importância como cidade de entreposto rodoviário.
The Nippon Challenge America's Cup 1992 - Progress in Hull Development
Authors: Nagami Yoshihiro 
Published: May 2021

In 1992, the class rule for the America's Cup was changed to the IACC. The Nippon Challenge decided that in order to build a successful challenger to a new class rule, the design would have to rely heavily on the results of a systematic series of tank and wind tunnel testing. The results of these simulations would then be used to build full scale boats which would be tested. The results of the full scale trials would be used to adjust the simulation techniques to fine tune the final design.
The data from the model tests were used to develop the input parameters for a Velocity Prediction Program (VPP). The VPP was used to determine the specifications for the design of the first two boats. After full scale testing, the VPP was compared to the results for about 6 months. After this verification and refinement of the VPP, a final boat was built. Finally the results of the race were evaluated and confirm that the basic design development process was correct.
Spatiotemporal patterns and ecological consequences of a fragmented landscape created by damming

Published: May 2021

BackgroundDamming disrupts rivers and destroys neighboring terrestrial ecosystems through inundation, resulting in profound and long-lasting impacts on biodiversity and ecosystem processes far beyond the river system itself. Archipelagos formed by damming are often considered ideal systems for studying habitat fragmentation.MethodsHere we quantified the island attributes and landscape dynamics of the Thousand Island Lake (TIL) in China, which is one of the several long-term biodiversity/fragmentation research sites around the world. We also synthesized the major findings of relevant studies conducted in the region to further ecological understanding of damming and landscape fragmentation.ResultsOur results show that the vegetations on islands and the neighboring mainland were both recovering between 1985 and 2005 due to reforestation and natural succession, but the regeneration was partly interrupted after 2005 because of increasing human influences. While major changes in landscape composition occurred primarily in the lakefront areas and near-lakeshore islands, landscape patterns became structurally more complex and fragmented on both islands and mainland. About 80 studies from the TIL region show that the genetic, taxonomic, functional, and phylogenetic diversity on these islands were mainly influenced by island area at the patch scale, but fragmentation per se also affected species composition and related ecological processes at patch and landscape scales. In general, islands had lower species diversity but a steeper species-area relationship than the surrounding mainland. Fragmentation and edge effects substantially hindered ecological succession towards more densely vegetated forests on the islands. Environmental heterogeneity and filtering had a major impact on island biotic communities. We hypothesize that there are multiple mechanisms operating at different spatial scales that link landscape fragmentation and ecological dynamics in the TIL region, which beg for future studies. By focusing on an extensive spatiotemporal analysis of the island-mainland system and a synthesis of existing studies in the region, this study provides an important foundation and several promising directions for future studies.
Interspecific-Competition Strongly Constrains Species-Richness and Species-Abundance Evenness in a Tropical Marine Molluscan Community Inhabiting Caulerpa Beds, as Compared to Coral-Reefs
Authors: Béguinot Jean 
Published: May 2021

Increasing species-richness at the local scale (within species communities) is accommodated, first, by the diversification of the niches respectively associated to species. Yet, in case of excessive supply in colonizing species issued from the regional pool, the corresponding increase in the number of solicited niches may lead to some “niche-overcrowding” resulting in significant niche-overlaps. Then, second, strong interspecific competition for shared resource can arise, triggered by the density in individuals among those species co-occurring at niche-overlaps. Accordingly, the accommodation of species-richness within a local community involves a balance between (i) the positive contribution of improved niche-diversification and (ii) the negative consequence of induced interspecific-competition at increasing niche-overlaps once the number of colonizing species becomes too large. This balance can strongly differ according to the local ecological conditions, since the latter are expected to strongly influence the range of “overcrowding-free” diversification of niches. So that, concretely, each community requires a specific analysis, in order to disentangle and quantify the respective contributions of the niche-diversification and the intensity of interspecific-competition to this balance. And, in particular, their respective roles upon both the species-richness and the degree of unevenness of species abundance within community. Beyond its speculative interest, this deeper understanding of the process involved in the hierarchic-like organization of species within community also answers more practical concerns, in particular the stability of species-richness, partly dependent on the intensity of interspecific-competition.
In this perspective, we quantify and compare how species-richness accommodation proceeds in two major taxonomic groups, Bivalves and Gastropods respectively, both belonging to a same molluscan community inhabiting Caulerpa beds, in the intertidal-zone of Siquijor Island (Philippines). Then, after having compared these two different taxonomic groups, the influence of environmental conditions on species-richness accommodation is addressed, showing that “Caulerpa-beds” habitat features far-less rewarding to Gastropods communities than can be the classical “coral-reef” habitat.

Published: May 2021

Aim: To find out the direct and residual effect of application of organics, inorganics and their combination on yield and yield parameters of rice-maize cropping system.
Study Design: The experiment was laid out in randomized block design during kharif season and split plot design during rabi.
Place and duration of Study: At Agricultural college farm, Bapatla during 2018-19 and 2019-20.
Methodology: After the preliminary layout, paddy was sown in kharif and maize was sown in rabi season. Vermicompost and green leaf manure were applied two weeks before sowing of paddy. Treatments applied for paddy were considered as main plots and each main plot was divided into two sub plots during rabi.
Results: Higher grain yield, straw yield, drymatter production at tillering stage were recorded with the application of 50% RDN through vermicompost +50% RDN through inorganics (T9) during both the years of study. However, in succeeding maize, the kernel yield, straw yield and yield attributing characters (drymatter, cob length and test weight) were significantly highest in the treatment which received 75% RDN through green leaf manure+ 25% RDN through inorganic (T5). Among the fertilizer levels applied to maize, S2 (100% RDF) recorded significantly higher dry matter production over S1 (50% RDF) at all the stages of crop growth and during two years of experimentation.
Conclusion: Substitution of 50 % N through vermicompost improved rice yield and yield attributes whereas substitution of 75% N through GLM have shown better residual effect in terms of improvement of yield and yield attributing characters of maize. Among the subplots application of 100% RDF significantly increased the yield when compared to 50% RDF.

Fish pond wastewater management is one of the problems having the greatest impact on the environment. This untreated fish pond waste water contains organic materials, pathogenic microorganisms, nutrients and toxic compounds, which when discharged into the environment and it runs off into the water bodies in excess could cause algal bloom (eutrophication) of the receiving waters. Port Harcourt is a riverine area, many of the fish farmers discharge their wastewater direct into the water bodies or into drainages that flows into the water bodies and this act is harmful to humans and the environment as a whole.
The determination of the microbiological and physicochemical characteristics and remediation of fish wastewater using Eichhornia crassipes and Pistia stratiotes were investigated. The physicochemical and microbiological parameters of fish pond wastewater were monitored at intervals from 1-70days. Fish wastewater samples were collected from twelve fish ponds (6 plastic tanks and 6 concrete tanks) using standard procedures. Identification of bacteria was carried out using colonial morphological and biochemical characteristics of the isolates. A total of 194 bacterial isolates belonging to eleven genera were identified from the twelve fish ponds with 6 concrete tanks having total heterotrophic bacteria, coliform counts, Salmonella Shigella counts, feacal coliform count, Vibro count, and Pseudomonad count that ranged from 4.78 ± 0.5×104 to 5.74 ± 0.39×105, 4.06 ± 0.06 ×104, to 5.8 ± 0.43 ×105, 4.3 ± 0.24×104 to 4.99 ±0.42 ×104, 4.18 ± 0.39 ×104 to 5.08 ± 0.43 ×105 , 4.08±0.35 x 105 to 5.24±0.46 x 105 and 4.1 ± 0.3× 104 to 5.15 ± 0.44 ×104 cfu/ml, respectively and 6 plastic tanks having total heterotrophic bacteria, coliform counts, Salmonella Shigella counts, feacal coliform count, Vibro count, and pseudomonad count that ranged from 4.55 ± 0.46×104 to 5.74 ± 0.4×105, 4.43 ± 0.23 ×104, to 5.78 ± 0.36 ×105, 4.00 ± 0.5×104 to 5.00 ±0.47 ×105, 4.18 ± 0.39 ×104 to 5.17 ± 0.45 ×105 , 3.78±0.35x103 to 5.24 ± 0.46x105 and 3.81 ± 0.26× 103 to 5.15 ± 0.44 ×105 cfu/ml, respectively. The bacteria isolates were Staphylococcus, Micrococcus, Bacillus, Enterococcus, Proteus, Pseudomonas, E. coli, Salmonella, Klebsiella, Vibrio and Shigella sp. The presence of these organisms is an indication of lack of qualitative pond management which could become harmful to both fishes andhumans in the food web systems. Therefore, there is the need to protect our water sources for aquaculture purposes and sustainable development through the detection of aquatic infectious substances and possible control of these microbes.

AbstractDoping is a powerful technique for tuning the electrical properties of organic semiconductors (OSCs). Although numerous studies are performed on OSC doping, thus far only a few n‐type dopants have been developed. Herein, two low‐cost nucleophilic organic bases are reported, namely 1,5,7‐Triazabicyclo [4.4.0] dec‐5‐ene (TBD) and 1,5‐Diazabicyclo [4.3.0] non‐5‐ene (DBN) for n‐doping of OSCs. The two dopants are found to significantly enhance the electrical conductivity of OSCs. In particular, compared to the classic n‐dopant 4‐(2,3‐Dihydro‐1,3‐dimethyl‐1H‐benzimidazol‐2‐yl)‐N, N‐dimethylbenzylamine (N‐DMBI), DBN results in significantly higher conductivity and also lower activation energy in N2200 films, indicating its high doping performance. The utilization of the n‐dopants for improving device performance and controlling the device polarity of organic field‐effect transistors are demonstrated. Furthermore, these dopants are employed for fabricating organic thermoelectric devices, and the power factor value of DBN‐doped N2200 films is found to be about 1.6 times higher than that of N‐DMBI‐doped films. These results show the feasibility of using low‐cost organic bases as efficient n‐dopants and demonstrate their promising applications in organic electronics.

Published: May 2021

AbstractLung cancer is one of the most rapidly growing malignancies in terms of morbidity and mortality. Although traditional treatments have been used for more than 50 years, it is still far from solving the problems of postoperative risks and systemic toxicity. Emerging targeting and immunotherapy are developing continuously and are gaining recognition; eventually, they face the inevitable challenge of drug resistance. Nanotechnology has several important effects on lung cancer treatment, owing to its unique properties. Several nanoparticle‐based treatments have successfully become cancer treatments. Good biocompatibility with higher specific surface area can carry substantial amounts of lung cancer treatment medications while avoiding medication toxicity; editable and modified characteristics give rise to multifunctional nanomedicines; excellent photoelectric effects make lung cancer a multimodal treatment. This article summarizes the breakthroughs achieved by nanotechnology, targeted therapy, and immunotherapy, reflecting the importance and necessity of nanotechnology in the treatment of lung cancer.

AbstractThe patterning of axonal and dendritic growth is an important topic in neural tissue engineering and critical for generating directed neuronal networks in vitro. Evidence shows that artificial micro/nanotopography can better mimic the environment for neuronal growth in vivo. However, the potential mechanisms by which neurons interact with true three dimensional (3D) topographical cues and form directional networks are unclear. Herein, 3D micropillar scaffolds are designed to guide the growth of neural stem cells and hippocampal neurons in vitro. Discontinuous and anisotropic micropillars are fabricated by femtosecond direct laser writing to form patterned scaffolds with various spacings and heights, which are found to affect the branching and orientation of axons and dendrites. Interestingly, axons and dendrites tend to grow on an array of 3D micropillar scaffolds of the same height and form functionally connected neuronal networks, as reflected by synchronous neuronal activity visualized by calcium imaging. This method may represent a promising tool for studying neuron behavior and directed neuronal networks in a 3D environment.
