Authors: Naher Aminun , Almas Lal K. , Guerrero Bridget , Shaheen Sania
Published: October 2023

The aim of this study is to visualize the historical changes in wheat and corn cropping patterns in the Texas High Plains from the perspective of geographical concentration and spatial autocorrelation. Historical county-level agricultural census data were collected from the United States Department of Agriculture and the National Agricultural Statistics Service from 1978 to 2017. Exploratory data analysis techniques were employed to examine the geographical concentration and spatial dependence of crop production among nearby locations. The results of temporal changes indicate that the harvested acres of corn and wheat tended to decrease throughout the study period. Total and irrigated harvested corn and wheat acreages were concentrated in a smaller number of counties over time while wheat production was mainly concentrated in the northern part of the region. The Moran’s I test statistic for total and irrigated areas of cropland suggest that there was spatial dependence among the neighboring counties in crop production in this region. In summary, there was a spatiotemporal change in cropping patterns in the Texas High Plains over the study period. Based on the results of the spatiotemporal changes in cropping patterns in the Texas High Plains, policy makers should promote and support non-irrigated varieties of crops in order to decrease the dependence on irrigation water from the Ogallala Aquifer.

Published: October 2023

The water inflow into tunnels will vary with the development of excavation damage zones (EDZs). Currently, there are few analytical studies on the evaluation of the water inflow into deeply buried symmetrical subsea tunnels, considering the influence of EDZs. Therefore, a solution was analytically developed using seepage mechanics, conformal mappings, and the superposition principle. The proposed solution was verified with a simplified solution and a numerical solution. A range of parametric analyses were performed to determine the effects of EDZs and spatial parameters on the water inflow, and an application to an engineering case was carried out. The results in this study reveal that the relative error between the proposed solution and the numerical solution is always less than 2.5% when the ratio of the buried depth to the radius of the tunnel is greater than or equal to 4. The water inflow increases significantly at an early stage of increasing the EDZ permeability coefficient, then gradually stabilizes and increases approximately linearly with the EDZ thickness. The effects of EDZs are greater with smaller buried depths and greater distances between the two tunnel centres. Compared with a single subsea tunnel, there is a diverting effect between the symmetrical subsea tunnels, which can be promoted by increasing the EDZ parameters. Moreover, this diverting effect increases as the buried depth increases and the distance between the two tunnel centres decreases. The application in this study shows that an increase of 13.82% to 30.42% in the water inflow occurred after considering the EDZs’ effects. The proposed solution can provide an efficient method to evaluate the water inflow into the deeply buried symmetrical subsea tunnels with EDZs.

Considering the importance of soil moisture in hydrological processes, it is crucial to understand the water distribution and time stability of different aerial shrub soils. There are few studies on the soil moisture of aerial vegetation in the northeastern margin of the Tengger Desert. Based on long-term monitoring data from the aerial seeding area in the northeastern margin of the Tengger Desert, the distribution characteristics of soil moisture and the temporal stability of soil moisture were studied. From June to October 2022, the soil moisture monitoring instrument WatchDog was used to monitor the long-term soil moisture changes (0–200 cm) in the four aerial afforestation plots of Hedysarum scoparium, mixed forest land (Hedysarum scoparium dominant species), mixed forest land (Calligonum mongolicum dominant species), and Calligonum mongolicum. The Spearman rank correlation coefficient was used to study the temporal stability of soil moisture in the four plots. Rainfall data were collected through small weather stations. The results show that the average soil water storage of four kinds of aerial shrub land in the study area was the highest in August, and the average soil water storage of different forest lands was different. The soil water content of the surface layer (0–30 cm) fluctuated the most in different months. The variation in soil water content in the shallow layer (30–100 cm) was smaller than that in the surface layer. The fluctuation of soil water content in the middle layer (100–150 cm) and deep layer (150–200 cm) was relatively stable. There was no strong variability in soil moisture content, and the temporal variation coefficient of surface soil moisture was the highest (31.44–39.8%), which showed moderate variability. The temporal variation coefficient of soil moisture in the shallow, middle and deep layers of all kinds of plots was significantly reduced, and the soil moisture stability of different aerial shrub land was the same. Spearman rank correlation analysis showed that the spatial pattern of soil water content in the surface layer (0–30 cm) and deep layer (150–200 cm) was more stable over time, that is, the temporal stability of soil water content was higher, and the temporal stability of soil water content in the middle and shallow layers of different types of shrub land was different. The research results help us to understand the soil hydrological process in the aerial seeding afforestation area in the northeastern margin of Tengger Desert, rationally arrange soil moisture monitoring points, efficiently manage and utilize water resources in the aerial seeding area, and provide a theoretical basis for local vegetation restoration and the optimization of the ecological environment.

Due to their toxicity, Cr(VI) levels are subject to strict legislation and regulations in various industries and environmental contexts. Effective treatment technologies are also being developed to decrease the negative impacts on human health and the environment by removing Cr(VI) from water sources and wastewater. As a result, it would be interesting to model and optimize the Cr(VI) removal processes, especially those under neutral pH circumstances. Microbial fuel cells (MFCs) have the capacity to remove Cr(VI), but additional research is needed to enhance their usability, increase their efficacy, and address issues like scalability and maintaining stable operation. In this research work, ANFIS modeling and artificial ecosystem optimization (AEO) were used to maximize Cr(VI) removal efficiency and the power density of MFC. First, based on measured data, an ANFIS model is developed to simulate the MFC performance in terms of the Cu(II)/Cr(VI) ratio, substrate (sodium acetate) concentration (g/L), and external resistance Ω. Then, using artificial ecosystem optimization (AEO), the optimal values of these operating parameters, i.e., Cu(II)/Cr(VI) ratio, substrate concentration, and external resistance, are identified, corresponding to maximum Cr(VI) removal efficiency and power density. In the ANFIS modeling stage of power density, the coefficient-of-determination is enhanced to 0.9981 compared with 0.992 (by ANOVA), and the RMSE is decreased to 0.4863 compared with 16.486 (by ANOVA). This shows that the modeling phase was effective. In sum, the integration between ANFIS and AEO increased the power density and Cr(VI) removal efficiency by 19.14% and 15.14%, respectively, compared to the measured data.

Published: October 2023

Chlorophyll-a concentration (Chl-a) is an important indicator of coastal eutrophication. Remote sensing technology provides a global view of it. However, different types of sensors are subject to design constraints and cannot meet the requirements of high temporal and spatial resolution on nearshore engineering simultaneously. To obtain high-spatiotemporal-resolution images, this study examines the performance of the enhanced spatial and temporal adaptive reflectance fusion model (ESTARFM) on GOCI and Landsat Chl-a data fusion. Considering the rapidly changing rate and consistency of oceanic Chl-a, the ESTARFM was modified via segmented fitting and numerical conversion. The results show that both fusion models can fuse multiple data advantages to obtain high-spatiotemporal-resolution Chl-a images. Compared with the ESTARFM, the modified solution has a better performance in terms of the root mean square error and correlation coefficient, and its results have better spatial consistency for coastal Chl-a. In addition, the new solution expands the data utilization range of data fusion by reducing the influence of the time interval of original data and realizes better monitoring of nearshore Chl-a changes.

Published: October 2023

Coastal wetlands are complex ecosystems that support biodiversity. They provide many benefits, including flood mitigation and sustenance for communities. The unique characteristics of wetlands make them vulnerable to natural and human-induced disturbances. Numerous factors, including industrialisation, urbanisation, and climate change, add to this phenomenon. The activities that threaten coastal wetlands in the world are relevant to coastal wetlands in Ghana. The Songor and Sakumo wetland catchments are international ecosystems endangered by land modifications and sea level rise. There are gaps in the body of knowledge that need investigation as regards underlying processes and transformation. This study assessed land use and land cover (LULC) changes between 1990 and 2020. The study used geospatial techniques and intensity analysis. LULC change results were from Landsat images (1990, 2000, 2011, and 2020). These changes were attributed to an increase in human activities. Changes in the Sakumo wetland catchment fell more into human-induced LULC categories, and vice versa for the Songor wetland catchment. The study recommends comprehensive methods of LULC change analysis. This would enhance biodiversity and allow the sustainable usage of wetland resources.
Understanding Nutrient Loads from Catchment and Eutrophication in a Salt Lagoon: The Mar Menor Case
Authors: Pérez-Martín Miguel Ángel
Published: October 2023

Eutrophication is a significant threat to aquatic ecosystems worldwide, and the Mar Menor hypersaline lagoon exemplifies a coastal lagoon at risk of algal blooms due to excessive nutrient loads, nitrogen, and phosphorus. These nutrients originate from various sources within the lagoon’s catchment area, including urban, agricultural, and livestock activities. Regular and occasional loads—during flood events—produce algal blooms that can significantly reduce the water oxygen content and cause massive mortalities, as observed in recent years. A daily algal growth model (Mmag) was developed to better understand the processes and determine key elements such as the phosphorus water–sediment interchange and deep water plants that effect the entire ecosystem and algal growth. The analysis developed can be applied in other wetlands around the world facing similar challenges. In the Mar Menor, both nitrogen and phosphorus have high relevance depending on the period of the year and the phosphorus legacy in the sediments. Floods are the main phosphorus input to the lagoon (80–90%), which goes to the sediment and is released after during the warm months in the following years. At the end of summer, phosphorus released from the sediment and the regular nitrate inputs to the lagoon increase the algal bloom risk. The good status of deep water plants, which reduces the phosphorus release in summer, is a key element to reduce the algal bloom risk. An integrated set of measures is required to reduce the mean chlorophyll to levels under 1 or 0.5 µgChla/L that can make the Mar Menor more robust and resilient.

The Institut de biologie appliquée (IBA) and Cepede vaccines (1918-1975) – Doctor of Science, neither doctor nor pharmacist, the destiny of the biologist Casimir Cepede (1882-1954) tipps in 1914 when he joins the antityphoid department of Professor Hyacinthe Vincent in Val-de-Grace.

During the first world war, he successfully develops a method for the preparation of non-toxic curative vaccines, presented at the Academy of Sciences by Edmond Perrier. In 1919, he creates the Institut de biologie appliquée (IBA) to broadcast his vaccine creations and offer them at low prices. He is an original scientist, an all-rounder, supported by political, arts and theater personalities.

He also faces administrative difficulties in registering his vaccines and sustaining his institute. The history of the IBA offers an offbeat look at the health and social issues during the twenties up until the fifties as well as conflicts between laboratories. After his death, his pharmacist daughter Annette Cépède (1911-1999) runned the family business until 1975, and kept on honouring the social commitments of his father. Since 2000, Casimir Cépède’s archives are deposited and searchable at the Institut Pasteur (Paris).

Misturas de borracha natural (NR) / copolímero de estireno e butadieno (SBR): análise teórica das formas de processamento através da modelagem molecular
Authors: Da Costa Helson Moreira , Ramos Valéria Dutra
Published: October 2023

Diferentes formas de processamento das misturas de borracha natural (NR) e o copolímero de estireno-butadieno (SBR) foram avaliadas do ponto de vista teórico através da modelagem molecular. Com o emprego da metodologia de campos de força AMBER, a energia de adsorção e o aspecto final de distribuição de ingredientes da composição e matrizes elastoméricas foram avaliados. Os dados teóricos, corroboram os experimentos encontrados na literatura, e indicam que a melhor forma de preparo da mistura corresponde ao método M2. Em tal método, SBR é misturado aos aditivos, posteriormente à borracha de NR e, por último, à massa homogênea, o acelerador é adicionado. Tal procedimento parece permite não apenas um balanço energético adequado entre fisissorção e quimissorção, segundo a modelagem molecular; mas também uma cura adequada do SBR, o elastômero menos reativo, segundo os experimentos. O resultado líquido, verificado na prática, é um desempenho mecânico superior dos vulcanizados NR/SBR.

Published: October 2023

Compreender a dinâmica florestal e sua relação com fatores de degradação é um problema complexo e envolve uma grande quantidade de variáveis (densidade florestal, umidade local, capacidade precipitação, quantidade de nutrientes, etc.) relacionados à fatores locais e globais em diferentes escalas espaciais e temporais. Neste trabalho propomos o estudo das condições de equilíbrio da densidade florestal, através de simulação computacional a partir de um modelo estocástico para estudo da evolução espaço temporal de incêndio, mediante uma taxa de propagação para um modelo discreto tanto do ponto de vista do tempo quanto do espaço. Entendendo que a taxa de propagação e degradação é uma função direta das outras variáveis dinâmicas da floresta, que têm influência sobre a densidade e a taxa de propagação local, o conhecimento de como o sistema se comporta em função dessas variáveis se tornam extremamente relevante. Para o estudo considerou se uma micro região dividida por sítios representada por uma matriz (N x N), com propriedades igualitárias em relação às variáveis ambientais que se refletem em uma taxa de propagação global para toda a micro região e realizamos uma estudo estatístico para um ensemble, sob essas condições para diferentes taxas.

In this paper, a novel distribution was proposed for modeling data on Leukemia and median effective dose (ED50) of Artemether-Lumefantrine against Plasmodium falciparum. Plasmodium falciparum or P. falciparum is one of the protozoan species that causes malaria. In the treatment of malaria, especially in sub-Saharan Africa Artemether-Lumefantrine dominates the hospitals. The ED50 (median effective dose) is the dose of a medication that produces a specific effect in 50\% of the population that takes that dose. The new distribution has three parameters that make it both flexible and tractable. The distribution is called the Gompertz-Lindley distribution. The model's hazard function behavior was presented together with the properties of the proposed distribution. The parameters were estimated using the method of maximum likelihood. From the analysis, the Gompertz-Lindley distribution is better than the competing standard distribution in the instances of the two data sets deployed.

Social innovation as a driver of economic development
Authors: Kan E. N.
Published: October 2023

Aim. To study theoretical and methodological aspects of the phenomenon of “social innovation”.

Tasks. To systematize the existing knowledge about social innovations, to identify the genesis of the concept of “social innovation”; to establish how the content of this concept has changed and in connection with what, what importance scientists assign to this concept at present.

Methods. The research was carried out with the help of methods of scientific knowledge (analysis of scientific works of foreign and domestic authors in the field of economics and management, synthesis of concepts and approaches).

Results. Theoretical aspects of social innovation have been studied. International and domestic works of scientists of different time periods and countries were analyzed. On the basis of the study the following definition was obtained: social innovations are innovations that are an effective tool to stimulate the solution of acute problems in society (in case of short impact), a trigger of transformations and/or a driver of economic development (in case of long impact), affecting the quality of institutions in order to improve the quality of life of people.

Conclusions. Despite the fact that the concepts of “innovation” and “sociality” developed independently and independently of each other, they have always evolved simultaneously. This is evidenced by the works of thinkers of all historical epochs, starting from the Ancient World. Moreover, with the passage of time there is a scientific “splicing” of these two concepts, which becomes most noticeable at the turn of the late XIX - early XX century, when the world is experiencing significant socio-economic and political events. More and more scientists raise pressing questions about what social innovation is - a derivative or a producer, an indicator or a tool, influencing institutions or being influenced by institutions. The significance of this study lies in the attempt to systematize theoretical and methodological aspects for further study of this phenomenon.

Assigning observations to highly separable although relatively homogeneous groups is still a challenging task despite the abundance of well-elaborated theories and effective, practical algorithms. Not just the aim of clustering then the underlying data itself influences the choice of method and the way of assessing the results. Outliers and non-normal data distribution can lead to surprising, unstable and many times undesirable clustering results especially in higher dimensions. This implies the importance of some human supervision in case of such unsupervised algorithms as well. In this paper a robust clustering alternative is presented based on the Most Frequent Value Method for crisp-type clustering in case of real-life data. The proposed approach is compared with the k-Medians algorithm. A favourable attribute of the applied procedure is its ease of application on multidimensional data sets where critical judgment of formed groups is particularly troublesome.

Ebben a munkánkban főként nemrég közölt explicit és stabil numerikus módszereket ismertetünk és hasonlítunk össze egymással és a szakirodalomból ismert explicit és implicit módszerekkel a hővezetési egyenlet megoldására. Ezen módszerek konvergenciáját és számítási teljesítményét megvizsgáltuk kétdimenziós, véletlen számok segítségével előállított inhomogén rendszereken végzett esettanulmányok segítségével. Egy közepesen merev, sőt egy erősen anizotrop rendszeren végzett numerikus tesztek eredményei azt mutatták, hogy az explicit numerikus módszerek jobban teljesítenek a széles körben alkalmazott implicit módszereknél.

Mesin produksi yang digunakan yaitu mesin horizontal mixer tipe pengaduk paddle mixer dengan kapastias 2.000 kg per batch serta memiliki 6 buah paddle. Perusahaan mengalami downtime tepatnya 1 tahun terakhir, yang mana pada bulan Januari 2022 – Januari 2023 sebesar 3.420 menit. Dengan adanya latar belakang permasalahan tersebut, penulis ingin melakukan analisis penyebab permasalahan yang menyebabkan downtime dengan menggunakan fishbone diagram. Dari hasil analisis, faktor yang dominan yang menyebabkan paddle mixer patah disebabkan oleh faktor mesin. Berdasarkan perhitungan nilai Overall Equipment Effectiveness mesin horizontal mixer tipe pengaduk paddle mixer di Koperasi Agro Niaga Jabung Syariah pada unit Sarana Produksi Pakan Ternak (SAPRONAK) yaitu sebesar 72.39% dengan availability sebesar 96.40%, performance sebesar 74.90% dan quality rate sebesar 99.98%. Hasil perhitungan nilai Six Big Losses masing-masing yaitu Reduced Speed Losses sebesar 23.90%, Idling and Minor Stoppages 5.27%, Breakdown Losses sebesar 3.30%, Setup and Adjustment sebesar 0.28%, Reject Losses sebesar 0.01%. Dari nilai ini dapat dilihat bahwa faktor Reduced Speed Losses dan Idling and Minor Stoppages Losses merupakan faktor losses dengan nilai tertinggi. Untuk mengidentifikasi failure mode menggunakan metode Failure Mode and Effect Analysis (FMEA). Dari hasil analisis FMEA diperoleh 4 failure mode yang terdiri dari patah pada paddle mixer, tombol panel listrik rusak dan kabel panel putus, rotor coil terbakar, motor housing pecah, roller bearing rusak dan kipas/fan rotor rusak, rumah gear box pecah, bearing macet, oli habis dan roda gigi aus. Untuk menentukan konsekuensi kegagalan yang ditimbulkan dari failure mode dan menentukan kebijakan preventive maintenance yang efektif untuk setiap mesin disesuaikan dengan klasifikasi LTA. Failure mode kategori A dilakukan dengan pengoperasian mesin sesuai SOP, kategori B dilakukan pemeriksaan mesin dan persiapan spare part dan kategori C dilakukan pemasangan yang tepat, pelumasan dan pembersihan.

Masyarakat di daerah kepulauan dan pesisir pantai sering mengalami kekurangan air, terutama musim kemarau. Pada daerah dimana masyarakat tinggal tersebut terdapat sumber energi dan air laut yang melimpah, terlebih pada musim kemarau. Pada kondisi ini sangat tepat menggunakan solar still untuk mengolah air laut menjadi air tawar menggunakan energi matahari. Penelitian ini bertujuan untuk membandingkan solar still double slope menggunakan pendingin nitrogen pada dinding (SSDS.WCN) dan tanpa pendingin SSDS. Penelitian dilakukan secara eksperimen, teoritis dan kajian eksergi. Solar still menggunakan pelat penyerap sirip berpori, kaca penutup double slope dan pendingin nitrogen pada dinding sebelah utara dan selatan yang di bandingkan dengan tanpa pendingin. Nitrogen pada sisi utara dan selatan menggunakan metode pembilasan (Flushing). Penelitian menghasilkan produktivitas air kondensat menggunakan pendingin nitrogen pada dinding (SSDS.WCN) secara eksperimen rata-rata sebesar 2.28 kg/10jam.m2 dan teoritis sebesar 2.15 kg/10jam.m2 lebih tinggi di bandingkan dengan tanpa pendingin (SSDS) secara eksperimen sebesar 1.98 kg/10jam.m2 dan teoritis sebesar 2.07 kg/10jam.m2. Efisiensi solar still menggunakan pendingin nitrogen pada dinding (SSDS.WCN) secara eksperimen rata-rata sebesar 37.05% dan teoritis sebesar 38.87% lebih tinggi di bandingkan dengan tanpa pendingin (SSDS) secara eksperimen sebesar 34.02% dan teoritis sebesar 35.27%. Efisiensi eksergi rata-rata menggunakan SSDS.WCN sebesar 4.78% dibandingkan dengan SSDS sebesar 4.49%. Solar still menggunakan pendingin nitrogen pada dinding dapat meningkatkan produktivitas air kondensat, efisiesnsi solar still dan efisiesnsi eksergi di bandingkan dengan tanpa pendingin.

PT.MJB Pharma merupakan perusahaan yang bergerak di bidang farmasi. Penghasilan terbesar yang didapatkan oleh perusahaan ini adalah berasal dari penjualan produk infus dengan tipe D5, NS, dan RL. Biasanya informasi mengenai permintaan konsumen terhadap suatu produk relatif stabil dari waktu ke waktu, namun permintaan dari toko ke penyalur (ritel) menuju ke pabrik jauh lebih fluktuatif dibandingkan dengan pola permintaan dari konsumen. Permintaan yang relatif stabil di tingkat pelanggan akhir berubah menjadi fluktuatif di bagian hulu supply chain dan semakin ke hulu peningkatan tersebut semakin besar yang disebut juga dengan bullwhip effect. Hasil yang diperoleh dari penelitian ini diantaranya bahwa error terkecil terdapat pada metode peramalan Holt’s Winter dengan parameter Level sebesar 0,5, Trend sebesar 0,2 dan Seasonal sebesar 0,6. Fenomena bullwhip effect pada data historis dapat diminimisasi dan dihilangkan dengan penerapan metode Vendor Managed Inventory (VMI) pada manufaktur dan setiap cabang distributor. Berdasarkan peramalan permintaan dan penentuan kebijakan jumlah pemesanan, maka didapatkan perkiraan nilai bullwhip effect yang terjadi setelah penggunaan VMI pada rantai pasok yakni 0,47036 pada level manufaktur, kemudian untuk level distributor dari masing - masing cabang adalah 0,713480715; 0,717343114; 0,669206602; dan 0,639086924. Berdasarkan perhitungan tersebut diperoleh bahwa persediaan pada manufaktur dapat memenuhi kebutuhan dari masing – masing pelaku rantai pasok. Hal ini dapat diterapkan apabila terdapat kolaborasi aktif antar pelaku rantai pasok dengan melakukan pengendalian persediaan dan peramalan permintaan yang tepat..
