Authors: Noordin Rumaizah Mohd , Istiqomah Titis , Ferdian Muh. Agus , Farida Siti
Published: June 2024

Integrity of attitude, behavior, openness and honesty are important things that capture fisheries business actors must have. Deviations in integrity are allegedly equivalent to criminal acts of corruption because they have the potential to cause very large losses to the state, which are difficult to detect and the value of the losses. In addition, failure to fulfill integrity has a huge potential for loss of sustainability of fisheries resources in the long term, and is difficult to recover. The research aims to examine the relationship between the integrity of capture fisheries business actors and efforts to preserve fish and marine resources. Descriptive research using a literature study approach combined with a limited discussion process with aquatic resource management experts in order tomaintain the sustainability of fish population dynamics due to capture fisheries exploration. The research results show that the integrity component which concerns attitudes, behavior, openness and honesty of capture fisheries business actors is an absolute thing that must be implemented and developed. Potential state losses worth billions of rupiah accompanied by massive damage to marine resources can be avoided if capture fisheries business actors carry out exploration properly and report their activities honestly and openly to the competent government authorities as a control over resource sustainability.

Published: June 2024

Coastal areas with mangrove forests are a natural landscape that has a unique environmental tone. In the past, this coastal area was a landing place for traders and religious leaders to preach. Developing this area into religious ecotourism is an economic potential that should be grown from integrated marine space management with sustainable exploration of coastal resources. The research aims to develop implementation strategy stages for the development of religious ecotourism in coastal areas and mangrove forests in the Southeast Asia region. Descriptive research with a qualitative approach. Data was obtained from cross-information between researchers at four different locations. Each researcher obtained empirical data from interviews and direct observations in the field. The implementation strategy was prepared using SWOT-BSC analysis with a combination of weightings, where each researcher reported the two most important aspects in the implementation feasibility approach based on observations at each of their nearest residential locations. Collaborative research provides general results that contain a compilation of different strategies. Aspects of the religious approach and aspects of revitalizing the role of coastal communities and indigenous communities are the main things that must be prioritized from the start to realize religious ecotourism so that it becomes a leading tourist destination in an area.
Testing the suitability of vector normalization procedure in topsis method: application to wheel loader selection
Authors: Bouhedja Mohamed , Bouhedja Samir , Benselhoub Aissa
Published: June 2024

The object of the research consists of testing the suitability of the vector normalization procedure (NP) in the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) method. One of the most problematic steps of the Multi-Criteria Decision Making (MCDM) process is related to the application of NPs by default to transform different measurement units of criteria into a comparable unit. This is because of the absence of a universal agreement that defines which NP is the most suitable for a given MCDM method. In the literature, there are thirty-one available NPs, each one of them has its strengths and weaknesses and, accordingly, can efficiently be applied to an MCDM method and even worst to another. Let’s note that many NPs (e. g., NPs of sum, max-min, vector, and max) have been used by default (i. e., without suitability study) in the TOPSIS method. Consequently, outcomes of multi-criteria evaluation and rankings of alternatives considered in the decision problems could have led to inconsistent solutions, and, therefore, decision-makers could have made irrational or inappropriate decisions. That’s why suitability studies of NPs become indispensable. Moreover, a description of the methodology, proposed in this research, is outlined as follows:
1) method of weighting based on an ordinal ranking of criteria and Lagrange multiplier (for determining criteria weights);
2) TOPSIS method (for ranking considered alternatives);
3) a statistical approach with 3-estimate (for comparing effects generated by the used NPs).
In the research, twelve different NPs are compared to each other in the TOPSIS method via a numerical example, which deals with the wheel loader selection problem. The results of the comparison indicate that, amongst the twelve different NPs analyzed in this suitability study, vector NP has the lesser effect on the considered alternatives’ evaluation outcomes, when used with the TOPSIS method. The vector NP-TOPSIS approach can therefore be applied to solve multi-criteria decision problems. Its application further allows the decision-makers and users to better select efficient solutions and, consequently, to make conclusive decisions.
Exploring an LSTM-SARIMA routine for core inflation forecasting
Authors: Krukovets Dmytro
Published: June 2024

The object of the research is the Core Inflation Forecasting. The paper investigates the performance of the novel model routine in the exercise of the Core Inflation Forecasting. It aggregates 300+ components into 6 by the similarity of their dynamics using an updated DTW algorithm fine-tuned for monthly time series and the K-Means algorithm for grouping. Then the SARIMA model extracts linear and seasonal components, which is followed by an LSTM model that captures non-linearities and interdependencies. It solves the problem of high-quality inflation forecasting using a disaggregated dataset. While standard and traditional econometric techniques are focused on the limited sets of data that consists just a couple of variables, proposed methodology is able to capture richer part of the volatility comprising more information. The model is compared with a huge pool of other models, simple ones like Random Walk and SARIMA, to ML models like XGBoost, Random Forest and simple LSTM. While all Data Science model shows decent performance, the DTW+K-Means+SARIMA+LSTM routine gives the best RMSE over 1-month ahead and 2-month ahead forecasts, which proves the high quality of the proposed forecasting model and solves the key problem of the paper. It is explained by the model's capability to capture both linear/seasonal patterns from the data using SARIMA part as long as it non-linear and interdependent using LSTM approach. Models are fitted for the case of Ukraine as long as they’ve been estimated on the corresponding data and may be actively used for further inflation forecasting.
Mechanism of interaction between zirconium dioxide and fluoride melts
Authors:   Institute of High Temperature Electrochemistry, Ural Branch of the Russian Academy of Sciences, Filatov Aleksandr A.
Published: June 2024

In this work, the mechanism of interaction between zirconium dioxide and fluoride melts was studied. Dissolution rates and maximum permissible oxide contents in the KF-AlF3 and NaF-AlF3 melts were determined under natural convection conditions at a temperature of 750 °C. The results of solubility measurement show that the limiting content of ZrO2 in the KF-AlF3 melt ([KF]/[AlF3] = 1.3) is 0.69 ± 0.10 mol. %, and in the NaF-AlF3 melt ([NaF]/[AlF3] = 1.3) at 800 °C it is 0.54 ± 0.04 mol. %. The calculated dissolution rate of zirconium oxide under these conditions in melts based on potassium fluoride and sodium fluoride is 0.022 mol/min and 0.017 mol/min, respectively. The influence of the cationic composition of the medium and the concentrations of additives on the liquidus temperatures of the melts was studied. It has been established that the increase in liquidus and solidus temperatures is facilitated by the addition of zirconium and aluminium oxides, as well as by the replacement of potassium fluoride with sodium fluoride while maintaining the molar ratio of the replaced cations. Analysis of thermal effects by differential scanning calorimetry (DSC) shows that, regardless of the molar ratio of the components, the onset of the thermal effect in melts based on potassium fluoride occurs at a temperature of 542 °C and in the systems with sodium fluoride additives at a temperature of 597 °C. Presumably, this dependence is associated with the melting of the KAlF4 and K2NaAl3F12 phases formed in the melts based on KF-AlF3 and KF-NaF-AlF3, respectively. It has been established that the melting of the KF-AlF3 mixture is accompanied with a mass loss of up to 1.3 wt. %, which is associated with partial evaporation of KAlF4.

Authors: Wan Zhihua , Li Yanzhong
Published: June 2024

Falling film evaporation has been proposed as a promising alternative to traditional pool boiling heat exchangers due to advantages such as lower pressure drop, heat transfer improvement, and refrigerant charge reduction. This paper provides a comprehensive review of recent advancements in falling film flow and heat transfer characteristics, specifically focusing on various surface structures, including smooth plates, corrugated plates, vertical tubes, and horizontal tubes. In the case of film flow on plates,
this review highlights key aspects such as film thickness, film wave evolution, wettability, and heat transfer properties. The study further reviews findings on film flow along both the inner and outer surfaces of vertical tubes, as well as horizontal round tubes and non-round tubes. The enhanced tubes can be divided into tubes machined with fins and coated with material. Noteworthy findings regarding flow pattern transitions, film thickness, and heat transfer characteristics on horizontal tubes are comprehensively outlined. Furthermore, the impact of external disturbances on film flow and heat transfer is also reviewed. Finally, several challenges and prospective directions for future research are established.
Micromechanical analysis of contact erosion under cyclic loads using the coupled CFD–DEM method
Authors: Cai Guo-Qing , Diao Xian-Feng , He Xu-Zhen , Gao Shuai , Liu Tao
Published: June 2024

Different layers of soil often have distinct particle sizes. When exposed to the natural environment, soil is easily affected by natural rainfall, rising groundwater levels and human activities, leading to particle contact erosion, which reduces the safety and service performance of the soil structure. In this paper, a coupled computational fluid dynamics–discrete-element method (CFD–DEM) model was employed to investigate the particle migration phenomena, mechanical response of contact interfaces, variations in flow fields and macroscopic deformation during the contact erosion process under cyclic loads at different frequencies and amplitudes. The conclusions are presented as follows. (a) Within one cycle of cyclic loading, both compression during loading and stress relaxation during unloading are the main factors triggering the migration of fine particles. (b) The migration and loss of fine particles mainly occur in the early stages of cyclic loading, where strong contact force chains are formed within the fine particle layer, leading to significant plastic deformation of the soil at the macroscopic level. (c) Under cyclic loading, changes in the soil pore structure cause an upwards hydraulic gradient in the initial quiescent water flow field. This hydraulic gradient can rupture weak contact force chains and cause particle pumping. (d) Increasing the frequency and amplitude of cyclic loading intensifies the erosion of fine particles, causing greater axial deformation of the soil. Compared to cyclic loading frequency, the amplitude of cyclic loading has a greater impact on contact erosion.
Optimisation of mechanical properties and pore structure of lightweight geopolymer concrete
Authors: Zhong Weiliang , Wang Hu , Zhao Xu , Li Junxia , Fan Lifeng
Published: June 2024

Lightweight geopolymer has good physical and mechanical properties, thermal and chemical stability and low carbon dioxide emissions. The development of high-strength lightweight geopolymer concrete (LGC) for load-bearing structures can expand geopolymer applications. The use of ground granulated blast-furnace slag (GGBFS) to improve the mechanical properties and pore structure of LGC was investigated. The ultimate compressive stress of LGC containing GGBFS were analysed, as well as the variation in microscopic pore structure. Specimens of LGCs with different strengths (LC20, LC30 and LC40) were investigated. As the GGBFS content increases, the ultimate compressive stress and specific strength of LGC increases, while the strain corresponding to the peak stress decreases, indicating that the mechanical properties and deformation resistance of LGC are improved. The carbon dioxide emissions of LGC are less than those of cement-based lightweight concrete, indicating that LGC has good sustainability. Moreover, the addition of GGBFS can produce more gel and reduce the volume proportion of capillary pores and air pores, resulting in LGC densification. Recommended GGBFS contents for strength grades LC20, LC30 and LC40 are 0–12.7%, 12.7–24.6% and 24.6–30%, respectively. The LGC is lightweight and has high strength, and has potential for application in civil engineering.

Objectives To describe patterns of skin checks for potential skin cancers in general practice and subsequent skin-related healthcare, and the associated costs. Study type Retrospective longitudinal health record linkage. Methods Patient encounters between 2010 and 2017 were extracted from clinical information systems at 73 general practice sites in Victoria, Australia, including Medicare billing information, from the MedicineInsight primary care dataset. The main outcomes were skin checks, skin-related healthcare up to 3 months after the skin check, and health system costs. Results There were 59 046 skin check encounters (0.7% of all general practice encounters) identified for 40 014 people with a median age of 52 years (interquartile range 36–67). Of these people, 26% had multiple skin checks. Of the subsequent skin checks, 28% were within 3 months of the initial skin check and 15% were after > 2 years. There was subsequent skin-related healthcare ≤ 3 months after 20% of all skin checks: 8% had a skin biopsy, 11% had a skin excision (of which 2% indicated a melanoma diagnosis, 29% keratinocyte carcinoma and 68% benign or other skin lesion), 2% had skin-related medicine prescribed and 5% had other skin-related treatment such as cryotherapy (not mutually exclusive). Ninety per cent of skin checks were billed as general practitioner (GP) consultations, including 65% as GP consultations of < 20 minutes although the proportion of longer consultations increased over time. The mean 3-month skin-related general practice health system costs for people without and with subsequent skin-related healthcare were A$58 and A$240, respectively, and up to a mean of A$595 for those having a melanoma excised. Conclusions Skin checks for potential skin cancers occur frequently in Australian general practice and accumulate substantial health system costs, with one in five skin checks resulting in subsequent treatment. This study adds to scarce real-world skin check and cost data in Australia.

Целью исследования является систематизация эколого-экономических факторов разработки и внедрения наилучших доступных (НДТ) технологий в области обращения с электронными отходами в соответствии с принципами рециркуляционной экономики.
Методологическую базу исследования представляют следующие научные методы: систематизация научных знаний и опыта в разработке критериев выбора НДТ (метод обобщений); изучение российской и зарубежной практики нормативного регулирования порядка обращения с электронными отходами (экономико-правовой анализ); выявление взаимосвязи между факторами, влияющими на эколого-экономическое развитие системы обращения с отходами электронной промышленности, и критериями выбора НДТ (аналитический метод); оценка условий для создания эффективной системы управления отходами электронной промышленности (индукционный метод).
Результаты исследования. В данной статье факторы, влияющие на эколого-экономическое развитие системы обращения с электронными отходами, описаны и соотнесены с критериями выбора наилучших доступных технологий. К таким факторам следует отнести экологическую составляющую анализа продукции (обоснована необходимость установления нормативного требования описания химического состава продукции электронной промышленности), экологичность градостроительного проектирования (приведены аргументы целесообразности разработки мер поддержки сборщиков и переработчиков отходов и размещения достаточного количества пунктов сбора и утилизации отходов на территории каждого региона), экологичность инженерных изысканий (показано, что для получения достоверных результатов изысканий необходима полная информация о составе отходов), экологичность инженерно-технических решений (зависит от вида проектируемого объекта, его мощности и особенностей размещения). В статье обосновано, что эффективное построение и функционирование системы обращения с электронными отходами возможно при ее формировании на национальном, региональном и локальном уровне.

Цель исследования состоит в рассмотрении подходов к анализу массовой культуры для более осмысленного понимания особенностей функционирования данного феномена в современном обществе.
Методологией исследования являются различные подходы к рассмотрению массовой культуры, представленные в трудах А. Шопенгауэра, Ф. Ницше, Г. Лебона, Г. Тарда, З. Фрейда, К. Ясперса, Х. Ортега-и-Гассета, К. Маннхейма, Э. Тоффлера, Ж. Бодрийяра, в которых изучаются особенности и функции массовой культуры, ее влияние на личность. Анализ феномена массовой культуры осуществляется на основе принципов системности и диалектики.
Результаты исследования. Проанализировав существующие подходы к рассмотрению массовой культуры, авторы делают вывод о том, что, несмотря на усложнение общества и появление разнообразных культурных форм, массовая продолжает доминировать. Тем не менее в связи с технологическими и социокультурными изменениями, трансформацией системы ценностных ориентаций возникает тенденция персонализации культуры, связанная с субъективизацией социальных процессов, изменением мотивации и характера потребления, стремлением к обретению идентичности. Массовая культура подстраивается под все более усложняющиеся потребности аудитории, предлагая ей престижные и индивидуализированные продукты. Элитарная культура перестает существовать как недоступная массам, а выступает в роли эталона и культурного образца.
Перспективой исследования является дальнейшее изучение массовой культуры в силу динамичности ее развития, а также особенностей функционирования данного феномена в условиях современной российской действительности.

BARRIERS TO THE ADOPTION OF SUSTAINABILITY PRACTICES IN SMALL HOTEL BUSINESSES: A QUALITATIVE STUDY IN GHANA
Authors: Tokro Lucinda Seyram , Dzitse Collins Dodzi
Published: June 2024

Purpose- By integrating sustainability into their business operations, small tourism and hospitality accommodation enterprises will not only contribute to achieving sustainable development goals 7, 9,12,13 and 14, but also promote a culture of environmental and social consciousness that aligns with the broader objectives of the United Nations’ Agenda 2030. Therefore, this study explores barriers to the adoption of sustainability practices among small hotel businesses in Ghana.
Methodology- Using a qualitative research framework and descriptive analysis method, face-to-face interviews were conducted with 16 small hotel managers in the Cape Coast Metropolis of Ghana. The interview technique was adopted because it allowed for the acquisition of detailed information from participants on barriers to the adoption of sustainability practices.
Findings- The findings revealed a spectrum of internal barriers: lack of awareness and understanding of sustainability principles, attitudes, negligence among hotel staff, and financial constraints. External barriers, such as owner interference in managerial decision-making, exploitative supplier actions, burdensome taxes and levies, and seasonal fluctuations with low hotel patronage, were also identified as the main barriers to the adoption of sustainability practices in small hotel businesses in Ghana.
Conclusion- The study concludes by recommending targeted sustainability education and training programs to enhance sustainability awareness and cost-effective practices, while changes in organizational structures such as empowering managers and fostering collaboration between owners and managers are imperative for effective sustainability adoption and integration. Additionally, small hotel businesses should diversify revenue streams beyond peak seasons and, with collaborative efforts, advocate for supportive policies and regulations at all levels to create a conducive environment for the adoption of sustainable practices.
COMPETITION LEVEL ANALYSIS FOR THE FINTECH SECTOR IN TURKIYE COMPARED TO GERMANY
Authors: Akturk Meliksah
Published: June 2024

Purpose- This study's objective is to observe Türkiye’s fintech market structure by their competitiveness results. To get a better observation Türkiye compared with a fintech-developed country as Germany. The inconvenient definition of fintech caused this study to examine 4 massive fin-tech sectors. Especially current situation of the financial-technology market there are several branches. The study refrains from the engineering-intensive branches to serve its purpose. The study includes; Payments, Lending, Personal Finance, and Insuretech branches. We expect to observe the competitive dynamics for several branches.
Methodology- The study selected the “entropy index” as a method. The entropy index shows the market depth for related sectors. It can be defined as a density analysis. We can make the index with at least 5 observations. However, the increase in the observation level causes the low-variance level index results.
Findings- The study made its index by the top ten firms by their sales revenue level. The study observes the market in 5 branches. The conclusion part supplied 5 different density results. In that situation, observations can be seen more specifically for the market. The study used the entropy density index to observe the competitiveness level of the market. Results were multiple because the branches were divided from the sector. Every branch has its dynamics. On the Türkiye side, we expect fewer companies than in Germany. However, in the personal finance sector, we can observe the competitiveness levels are close. However, in this study, we can also observe high gaps between the sectors of insurance tech and lending. This study did not have the purpose of determining the factors behind them but the study tried to give political suggestions.
Conclusion- The density level for lending and personal finance sectors can be compatible with a high-fintech level company. For the insure-tech side, companies value and numbers are lower. The payment sector has more technology than the other sectors but the number of firms are lower than in Germany. We were expecting the competitive structure are not improve in Turkey because of the low-quantity firms. At some branches, we obtained the results that support this expectation. However, the view of the study observed that some branches has low competitive market structure when compared the Germany. But at some points, there are massive cliffs between the two countries. We can attribute the situation to the habits. The habits of technology meant. Especially on the insurance side, Turkey should improve itself. Türkiye should be getting more investment, subsidies, etc. in the sector of insure-tech and payment sector. Because their competition level is a risk to the country’s market structure. This study includes no detailed politics but suggests to subsidies and incentives from the government side. Government should support and encourage the new-entry firms or entrepreneurs for the sector of fintech.
Landslide Susceptibility and Risk Mapping in the Tectonic Ensemble Comprising of Eastern Himalayan Zone, Northeast India and Bhutan using Logistic Regression and Random Forest Techniques
Authors: Sengupta Arnab , Nath Sankar Kumar
Published: June 2024

The mountainous terrain of the East-Northeast tectonic ensemble covers an approximate area of 3,11,420 km2 comprising the Eastern Himalayan zone, Northeast India and Bhutan is prone to mass movements. The increasing trend of landslide occurrences in the last few decades sets loud alarm bells for mapping the landslide hotspot zones in terms of Landslide Susceptibility and Risk. Initially, a landslide inventory of around 9751 landslides has been prepared, of which 6826 (70%) has been randomly picked as training dataset and the remaining 2925 (30%) as the testing dataset. Thereafter, Random Forest (RF) and binary Logistic Regression (LR) based Landslide Susceptibility Zonation (LSZ) have been prepared through twelve predictor layers viz. Slope Angle, Slope Aspect, Slope Curvature, Distance to Drainage, Distance to Lineament, Landform, Surface Geology, Distance to Road, Normalized Difference Vegetation Index (NDVI), Landuse/ Landcover (LULC), Rainfall and Epicentre Proximity. Both the Landslide Susceptibility Index (LSI) maps are divided into five classes, viz. ‘low’, ‘moderate’, ‘high’, ‘very high’ and ’severe’, which are then validated statistically by drawing a comparison with the 30% testing chronological landslide inventory database. The statistical index based accuracy assessment in terms of Area Under the Curve (AUC) exhibits an LR model AUC of 0.776 and RF model AUC of 0.820. However, it has been observed that the RF model strongly correlates with the testing inventory dataset exhibiting that around 46% of the landslide-prone terrain is classified in the ‘high to severe’ zones with 41% inventory landslides occurring in these zones. Integrating the Random Forest (RF) based LSI thematic layer with the socio-economic vulnerability layers like the Number of Households and Population Density have demarcated around 20.78% of the region under ‘very high to severe’ socio-economic risk as convoluted by landslide susceptibility in the terrain. The present findings are expected to be useful in urban development and town planning with appropriate slope management and land-use planning.

Published: June 2024

Oxidation of the methyl linoleate with singlet oxygen, generated chemically by the sodium molybdate/hydrogen peroxide system (Na2 MoO4 /H2 O2 ), was studied in a type microemulsion micelle inverted (O/W). The monitoring of methyl linoleate oxidation with singlet oxygen was carried out using a UVVis spectrocopy, measuring the absorbance at 234 nm corresponding to the conjugated hydroperoxides. Under room temperature and pressure, products of the decomposition of possible dioxetane were not identified by HPLC and GC-MS, as some studies have suggested.
Energy and Exergy analysis of a light duty diesel engine operating at different altitudes
Authors: Agudelo John , Agudelo Andrés , Pérez Juan
Published: June 2024

Altitude above sea level produces a reduction in air density affecting the combustion process, pollutant emissions, and engine performance. In this work the combustion diagnosis of an automotive turbocharged diesel enginewas carried out from in-cylinder pressure signal. Tests were performed at three altitudes above sea level, under steady state operating conditions, using conventional diesel fuel. As altitude above sea level increased, the fuel/air mixture became richer. The brake specific fuel consumption, combustion duration, premixed combustion phase, maximum temperature, heat rejected to the gases and exergy destruction were also increased; at the same time, brake thermal efficiency, maximum in-cylinder pressure and in-cylinder exergy decreased. Mechanical efficiency and injection timing remained approximately invariable. Exergy destruction differences were caused by the combustion process, without significant effects during compression and expansion. The greater irreversibility resulting from altitude increase was linked with the lower energy quality of the exhaust gases.

The purpose of this paper is to present the results obtained in an experimental study that analyzed the performance of different concrete mixes. These mixes were produced with 90% of ordinary Portland cement (OPC) and the other 10% with the additions of metakaolin (MK) and silica fume (SF). Four types of MK were tested; two of these were produced by a thermal treatment on Colombian kaolin. The others two were imported from the international commercial market. The factors evaluated in all the concrete mixes were the following: compressive strength, water absorption and total volume of permeable porosity, capillary absorption, carbonation depth and chloride penetration. The concrete samples were submitted into an accelerated carbonation process inside a climatic chamber (30º C, 70% H.R. and 2.25% CO2 ). At 28 days of curing the carbonation depths for the blended concrete mixtures were greater than the one obtained in the OPC concrete without addition. With a prolonged curing age in all samples, with or without mineral additions, tend to slow the carbonation rate in the concrete. The resistance of the concrete to the chloride penetration was evaluated according to ASTM standard C1202. This study proved that blended concrete specimens have a lower capillary absorption and a higher chloride penetration resistance once these were compared with OPC concrete specimens without addition.

A methodology for shipment priority is shown which combines the information provided for several of these factors contained in a series of indicators of logistical nature, in the case of shipments from one warehouse to N retailers. By means of the use of AHP, the importance of a client is determined regarding another for the situation of one product with a periodic review replenishment policy. Besides, an operational methodology is shown for priority of goods dispatch in a dynamic environment.
K-statistical operators for set mathematical morphology
Authors: Díaz de León Juan Santiago , Gamino Arturo , Salgado Julio , Trujillo Valentín
Published: June 2024

A generalization of the basic operators in mathematical morphology is presented in this paper. The resulting generalization lead to the construction of the k-statistical operators, due to its ability to obtain geometricaly the statistical descriptors within the range of the operator (Z={0,1}). These operators can be less strict as to the expected result as in the basic operators of dilation and erosion. Furthermore, a single k-statistical operator represents a functional complete set that includes erosion and dilation as particular cases. In a k-statistical operator, the condition to obtain the resulting set depends on whether the area (number of elements) of intersection between the translated structural set and the original set is at least equal to k. As a consecuence, a single parameter (k) is able to create a manifold of operators ranging from erosion to dilation. Hence, other kinds of openings and closings with new behavior are created as alternative solutions to binary image processing problems.
Aglomeración de micropartículas de látex: simulación y verificación experimental
Authors: Fernández-Morales Flavio Humberto , Duarte Julio Enrique , Martí Josep Samitier
Published: June 2024

Manipulation of micrometric objects at the single level is one of the most important research fields because these techniques can be applied to handle biological material. The objective of this paper consists of presenting a microsystem designed for particle microhandling. The operating principle of the device hinges upon dielectrophoresis, which is the lateral motion of electrical neutral matter under the influence of non-uniform electric fields. In practice, the device was made on a silicon substrate onto which interdigitated castellated microelectrodes made of platinum were patterned by lift-off. Moreover, the microchamber walls were patterned in a photocurable resin which allows a constant sample volume during the experiments. Besides this, the chip was tested with polystyrene microspheres of 4.2 µm in diameter and some results of common dielectrophoresis and particle clustering are also presented. Microparticle aggregation patterns are consistent with the electric field profile calculated by the finite element method over the electrode surface.
Measured pressures on the basis of bottom slab with gaps in the flow direction in a channel

Published: June 2024

A study was conducted to determine whether the back edges of the longitudinal gaps of a floor tile fixed to the bottom of a canal with a supercritical flow convert kinetic energy into pressure energy using Froude numbers in the range of 2.84 to 10.12. In each test the pressure was measured on 16 points on the bottom surface of the tile with piezo-resistive transducers along three longitudinal lines: one central line with 8 sensors and two lateral lines with 4 sensors each on either side of the central line. In this manner the distribution of the median pressures under the test tile was determined. The test tile is similar to those used in civil engineering structures for the purpose of avoiding the erosive action of the turbulence of a supercritical flow. The analysis of the measured pressures shows that even when the top surfaces of the canal floor and of the protective block are in the same horizontal plane, the back edges of the longitudinal gaps transform the energy of velocity into pressure energy. In such a way a factor has been identified that intervenes in the production of the hydrodynamic force that lifts revetments of different structures, and that has until now been ignored in the study of this problem.
Primary productivity and humic substances in the swamp el eneal, San onofre Sucre-Colombia
Authors: Ríos Elkin Libardo , Palacio Jaime Alberto , Aguirre Néstor Jaime
Published: June 2024

In the period may 2003 and april 2004 the primary productivity and the contents of humic substances were determined in the swamp El Eneal. In the pelagic zone, the productivity was measured and samples were taken from water for the analysis of humic substances. The swamp system of the Eneal presents a oligotrofic state, with a reduced production at the time of rain. In contrast, at dry time, when the water level diminishes, the production is greater and the oxygen levels are higher, due to the presence of the submerged macrophyta Najas guadalupensis. It was associated to the low presence of plankton and disposable nutrients.
