The Riads of Morocco as tourist accommodation products: characteristics and potentialities
Authors: SELKANI IKRAME
Published: January 2023

Riad and dar ‘house’ are frequently confused, but with the following elements, we can tell the difference. Riads are likewise larger and more spacious than dars, although not to the level “ground floor + first floor”, as they are designed for almost four generations of the same family under one roof. Riads feature an exterior façade comprising a blind wall to 8 meters high, completely neutral, with nearly no windows. These Riads were erected to prevent indiscreet eyes from seeing inside.  In the middle of the Riad, there is a fountain, richly decorated in zellige ‘tiles’ and carved plaster, surrounded by four separate gardens, containing lemon, fig, mint trees…, giving off a subtle fragrance for the locals. In Morocco, Riads are very common in the old ‘Médinas’. These houses benefit from a very rich history made through its own architecture. They were initially houses of notables, keen to protect the privacy of their families. Nowadays, Riads have been restored for a touristic objective as guest houses where the visitor encounters a comfy area, frozen in another time. Rabat, Meknes, Fez, and Marrakech are the cities that have been nominated for the World Heritage by UNESCO. This list is not complete, but these cities were chosen to expand the Riad phenomenon in the country. In this paper, we will discover the history of the Riads through their architecture giving some examples.

As parcerias público-privadas no sector do turismo em Niassa (Moçambique) como factor dinamizador do desenvolvimento local
Authors: ADAMUGI USSENE IASALDE DAS NEVES , UITROSSE ASSANE CALISTO
Published: January 2023

Esta pesquisa pretende analisar as parcerias público-privadas no sector do turismo em Niassa como factor dinamizador do desenvolvimento local, assim como identificar as instâncias turísticas da Província do Niassa (Moçambique); descrever a relação destas instâncias com a população local; caracterizar a influência destas instâncias no desenvolvimento local. Considerando estes objectivos, recorreu-se ao método de investigação qualitativa, procurando recolher a opinião de um painel de profissionais e académicos especialistas nas áreas do turismo, gestão de projectos turísticos e financiamento na Direcção Provincial de Cultura e Turismo .Os resultados da investigação demonstram que regista-se um conhecimento superficial sobre o potencial destes locais turísticos e pouco contribuem para o desenvolvimento local; a maior parte dos proprietários das instâncias da província de Niassa preferem contratar pessoal estrangeiro, sobretudo do vizinho Malawi para sectores como hotelaria, cozinha, mergulho e restauração por temer admitir moçambicanos sem formação; não existem  uma ligação plena com a comunidade local, não restam duvidas que nestes locais turísticos não são  exploradas as potencialidades de âmbito cultural local como um atractivo  para ser oferecido ao turista.

Tasmania. Un destino de turismo aborigen y de naturaleza al alcance de todos
Authors: RUIZ DORA
Published: January 2023

Desde que los exploradores, conquistadores y aventureros comenzaron a ampliar nuestros horizontes geográficos, el mundo no ha hecho más que empequeñecerse. Con la tecnología actual, además, tenemos el mundo a nuestros pies y podemos acceder a la información y al conocimiento de cualquier lugar del Planeta con la misma facilidad que en nuestros propios pueblos y ciudades de residencia. A través de los restaurantes, supermercados, centros comerciales y grandes intermediarios en Internet también podemos adquirir productos de todos los rincones del mundo. Pero detrás de todos estos avances existe un mundo de transporte contaminante, emisiones de gases efecto invernadero, explotación de los recursos naturales, problemas de deforestación, etc. que nos hace ver la necesidad de buscar alternativas para que nuestro planeta Tierra deje de sufrir. En este sentido, conviene reflexionar sobre cómo cambiar nuestros hábitos de viaje y tener más sensibilización por los destinos de naturaleza con sistemas de aprovechamiento de los recursos territoriales y de producción local de alimentos más sostenibles y ecológicos, primando la utilización de técnicas tradicionales con otras compatibles con la conservación y valorización del medio natural, como es el caso de Tasmania, estado insular de Australia.

La puesta en valor turístico-cultural del legado "juanramoniano" en los espacios públicos de Moguer (Huelva, España)
Authors: OLLERO LARA SERGIO
Published: January 2023

El Premio Nobel de Literatura de 1956, Juan Ramón Jiménez Mantecón, dejó a su localidad natal inmortalizada en sus versos. Fue testigo privilegiado del Moguer de finales del siglo XIX y principios del XX, que aún miraba a la mar como los intrépidos marinos que se alistaron con Cristóbal Colón en 1492. El poeta dejó un legado material e inmaterial irrepetible, así como consiguió que Moguer fuese un importante destino turístico y literario casi un siglo después. Alejándonos de los recursos patrimoniales y turísticos convencionales como museos, conferencias o publicaciones, pretendemos analizar cómo se han amoldado las políticas culturales de la ciudad para ofrecer el legado literario y el producto turístico de Platero y yo en los espacios públicos mediante cuatro mecanismos: la toponimia evocadora de las calles, la Feria 1900, el museo al aire libre Platero Escultura y el proyecto de azulejos con los poemas de Juan Ramón que referencian personajes y sitios de Moguer.

Crecimiento turístico, desarrollo inmobiliario y geodiversidad: análisis preliminar de las dificultades de geoconservación en la Sierra meridional de la ciudad de Tandil, provincia de Buenos Aires, Argentina
Authors: SCHNEIDER GONZALO , RAMOS ALDO , VALENZUELA SILVIA
Published: January 2023

En el actual contexto posmoderno las dinámicas turísticas han mutado. Esto se expresa en el sistema territorial de Tandilia (Argentina), particularmente en el sector serrano sur de la ciudad de Tandil, donde sus características intrínsecas, como la geodiversidad territorial, le otorgan valor y producen una diferenciación del área, convirtiéndola en escenario de transformaciones territoriales vinculado a la práctica turística de diversa índole. Muchas de estas transformaciones, no obstante, se hacen en detrimento de la geodiversidad y la geoconservación de dicho espacio. El presente estudio pretende analizar las transformaciones y el vínculo entre los consumos turísticos, la geodiversidad y la geoconservación territorial de dicho sector. Para el objetivo de la presente investigación se realizó un análisis multitemporal de las transformaciones vinculadas a los consumos turísticos en el área de estudio desde una perspectiva de tipo descriptiva, a partir de la comparación de imágenes satelitales extraídas de diversas fuentes. A esto se le sumó el relevamiento de fotografías de puntos de interés en el territorio para el presente análisis.

Análisis del perfil turístico de la población del cantón de Cuenca (Ecuador) con aplicación de la teoría de Plog
Authors: AMÓN VICUÑA ANAÍS , FLORES QUEZADA PAULINA , VINUEZA MALDONADA MAYRA
Published: January 2023

El continuo crecimiento de la actividad turística ha generado que surjan nuevos gustos y preferencias, no sólo en cuanto al turismo receptor sino también al turismo emisor; es por ello que la creación de un perfil de turista emisor y su análisis, desde una perspectiva general empleando la teoría de Plog puede servir para conocer las necesidades y expectativas y a trazar una tendencia turística y una estrategia de promoción adecuadas. Este estudio se enfocó en el cantón de Cuenca (Ecuador), en donde tras una revisión bibliográfica se destacaron estudios acerca del perfil del turista visitante, más no un análisis de su propia población. El estudio tuvo un enfoque cuantitativo, con un alcance descriptivo-correlacional y con un corte transversal. Para la correlación de las variables se aplicó la prueba no paramétrica Chi cuadrado, la cual nos permite realizar una prueba estadística para evaluar hipótesis acerca de la relación entre dos variables categóricas. Se encontró que el mayor número de turistas del cantón Cuenca se relaciona con la demanda psicocéntrica, es decir, viajeros que buscan destinos conocidos y desarrollados que utilizan servicios turísticos que les proporcionen seguridad y confort, inclinándose por un turismo masivo más o un turismo de sol y playa convencional.

Published: January 2023

Seasonal variations of the fatty acid profile of deep-sea whip lobster Puerulus sewelli (Decapoda, Palinuridae), harvestedfrom the south-west coast of India were compared. Fatty acid contents showed seasonal fluctuations, with eicosapentaenoicacid and docosahexaenoic acid being predominant during the post-monsoon and winter seasons (9-11% of cumulative fattyacids). P. sewelli was found to possess considerably higher C20-22 n-3 fatty acids during these seasons along with balancedn-3/n-6 (>2) and polyunsaturated/saturated fatty acid ratio (≥1) than those in pre-monsoon. Greater hypocholesterolemic/hypercholesterolemic ratio (>2.4) and lesser atherogenicity (<1.8) and thrombogenicity (<0.3) indices qualify P. sewelli anideal health food. This study comprises the first report on fatty acid profile from commercially important deep-sea whiplobster P. sewelli.

Comparative storage stability of shrimp (Metapenaeus spp.) pickle at room temperature and refrigerated temperature
Authors: S. Tanuja  , Jeeva J. C. , Rout E
Published: January 2023

One of the determinants of consumer demand for any value added product especially that of a perishable item like fish/shrimp is its shelf life. Pickling has long since been one of the effective ways to preserve perishable foods for the lean season. The present study was designed to assess the biochemical and microbiological quality of shrimp pickle stored at room temperature and refrigerated temperature (4oC). The recipe for preparation of the product was decided based on the consumer preference of the region. The pH, which is considered as the most important criterion determining the shelf life in pickle, remained below 5 in both the treatments throughout the storage period of six months (p=0.053). All the biochemical parameters except total volatile nitrogen (TVN), remained with in the acceptable limit throughout the storage period in both the treatments, although the values were low for pickle stored at refrigerated temperature. There was no significant difference in TVBN value of pickle stored at refrigerated and room temperature at the end of six months (p=0.072). The TVN value did not correlate with organoleptic evaluation of the pickles stored at both room temperature and refrigerated condition. As per the organoleptic evaluation, the pickles were in acceptable level even after six months of storage and the sensory quality was not significantly different between the two treatments (p=0.225). Consumers perceived taste, price, appearance and health factor as the most important attributes that would determine the acceptability of a product.

Published: January 2023

Population dynamics of the brown shrimp Metapenaeus monoceros (Fabricius, 1798) was studied along the Indian coast using catch and effort data of trawlers from 8 States and 2 Union Territories for the period 2007-2015. Classical length-based stock assessment methods and spatial database of the shrimp catch were used to derive fishing ground related conclusions. Inclusion of spatial data revealed the possibility of existence of metapopulations of M. monoceros in the region. Maximum sustainable yield (MSY) cannot be a reasonable reference point for deciding the fishing pressure in M. monoceros. By analysing stock fluctuations noticed during the study period with varying spawning stock biomass combinations, retention of 40% spawning biomass seems to be a safe option for sustaining M. monoceros production from Indian waters. Based on this, the study recommends reduction of fishing pressure along north-west, south-west and northeast coast by 70, 60 and 70% respectively from the base level of effort in 2017. The study illustrates that the spatial data from fishing ground, can serve as an additional tool to derive management options. The study also emphasises the need for further investigations on the possibilities of metapopulations of M. monoceros which is widely distributed in all agro-climatic zones along the Indian coast.

Influence of an exogenous androgen, testosterone propionate on milt quality and short-term preservation of milt of Asian seabass Lates Calcarifer
Authors: Chithambaran Sambhu , Al Harbi Mamdouh
Published: January 2023

Asian Seabass Lates calcarifer is widely used for pond and cage culture practice in the Kingdom of Saudi Arabia. A studywas carried out to understand the influence of an exogenous androgen, Testosterone propionate (TP) on milt quality ofL. calcarifer. Intramuscular injection of TP at dose 1.0 ml kg-1 was given to mature male fishes grown in a brood stockpond. A control was also maintained without giving hormone injection. After 36 h of injection, milt was collected and miltquality was assessed for colour, sperm cell concentration, motility and viability of spermatozoa. Short-term preservation ofmilt was carried out in oxygen and marine teleost Ringer’s medium at 4oC for 120 h. No significant change was observedin colour and pH of milt, but nature of milt changed from thick to watery due to hormone injection. Enhanced milt volume(14%) and sperm cell concentration (4%) was noticed in fishes from the treatment group 36 h post-injection, when comparedto control. Sperm motility duration and percentage motility were high in treatment fishes than control. Milt preserved inoxygen medium showed high sperm motility and viability when compared to Ringer’s medium. Intramuscular injection ofTP at 1.0 ml kg-1 improved milt volume and quality and therefore can be used for induced breeding of Asian Seabass.

Invasive suckermouth armoured sailfin catfishes of Pterygoplichthys genus is a threat to natural fish biodiversity. Weattempted to identify suckermouth armoured sailfin catfishes, Pterygoplichthys spp. which have successfully invadedand established in the East Kolkata Wetland, using morphological and molecular techniques. Based on the colourationpattern/spot on the belly region they were categorised into three groups viz., Pterygoplichthys pardalis, Pterygoplichthysdisjunctivus and an intermediate group. In total, fin clips from 32 individuals were collected from the above three groupsand a portion of mitochondrial cytochrome oxidase subunit-I (COI) gene was sequenced using Sanger’s method. Out of the32 individuals, good quality sequences were obtained for 30 individuals. Surprisingly, mtDNA COI gene sequence analysisrevealed that a sequence length of 581 bp was identical among all individuals. Species level barcode records from BOLDdatabase revealed the identity of specimens in all categories as P. pardalis. Results of the study suggest that Pterygoplichthysestablished in East Kolkata Wetland might have originated from a single reproducing entity.

The present study was undertaken to assess the interrelation between water quality and nutrient status of three reservoirssituated in Tamil Nadu, India. These three reservoirs are managed by the Public Works Department (PWD) with the fisheriesaspects falling under the purview of Tamil Nadu State Fisheries Department. In each reservoir, inflow and outflow sectionswere identified as sampling sites. A total of six sampling sites were fixed and monthly sampling for water and fish wasconducted during the period from October 2019 to June 2020. The various physico-chemical parameters such as temperature,electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), total volatile solids (TVS), turbidity,DO, pH, alkalinity, hardness, chloride, sulphate, biological oxygen demand (BOD) and chemical oxygen demand (COD)were analysed. Biological parameters like chlorophyll-a and primary production as well as various nutrient parameterswere also analysed in the collected water samples. All the physical and chemical water quality variables showed significantvariation (p<0.05) in their concentrations within various months and between stations. All the water quality parameters wereobserved to be within the prescribed limits. The results indicated under-exploitation of fishes from the reservoirs and suggestways to improve fish yields and livelihood of local fisher community.

Potential of enzymatically hydorlysed seaweed products as cost-effective nutrient media for growth and lipid enhancement in the marine microalga Nannochloropsis salina
Authors: Krishna Moorthy Abarna  , V. Rani  , P. Padmavathy  , P. Jawahar  , A. Uma  , C. Kalidas
Published: January 2023

Enzymatically hydrolysed seaweed products (EHSPs) prepared from the red seaweed, Gracilaria corticata (EHSP-1) and brown seaweed, Stoechospermum marginatum (EHSP-2) contained abundant levels of macro, micro and trace elements necessary to fulfil the nutritional requirement of the microalga Nannochloropsis salina. EHSP-1 had higher levels of N, P, K and Fe in comparison with EHSP-2. The growth performance of N. salina suggests that EHSP-1 was more efficient than EHSP-2. The growth rate of N. salina in EHSP-1 was 1.07 times higher than the control whereas in EHSP-2 the growth rate was 0.58 times lower than the control. The maximum biomass concentration of N. salina was achieved in EHSP-1 and EHSP-2 were 0.37 and 0.21 g l-1 with a biomass productivity of 0.027 and 0.0152 g l-1 d-1 respectively. The results of biochemical analyses also suggest that protein, pigment and lipid yield of N. salina was positively stimulated by EHSP. The findings suggest that the best concentration of EHSP-1 and EHSP-2 to achieve maximum biomass and lipid production of the marine microalga N. salina were 8 and 4% respectively. EHSP-1 enhanced the biomass and lipid production without affecting the nutritional properties of N. salina suggesting its potential applicability in aquaculture, biofuel and other related industrial sectors.Keywords: Cellulase enzyme, Indigenous seaweed resources, Nannochloropsis salina, Nutrient rich media

Madhyamaka and Advaita Vedānta on the Ontology of Time
Authors:   Institute of Oriental Manuscripts, Russian Academy of Sciences, Burmistrov Sergey L.
Published: January 2023

Fundamental difference between Buddhist Mahāyāna school of Madhyamaka and Brāhmaṇic school of Advaita Vedānta in interpretation of ontology of time is analyzed on the basis of Nāgārjuna’s (2–3rd cc.) treatise Mūla-madhyamaka-kārikā, Candrakīrti’s (7th c.) commentary Prasannapadā, Vasubandhu’s (4th c.) treatise Abhidharmakośa, Asaṅga’s (4th c.) Abhidharma-samuccaya, Śaṃkara’s (9th c.) commentary to Bādarāyaṇa’s (2nd c.) Brahma- sūtras and Sadānanda’s (15th c.) Vedāntasāra. Time according to Madhyamaka is the result of the activ­ity of consciousness blinded by afflictions (kleśa), and therefore it is just mental construction having no referent in reality. There is no time in true reality, for time presupposes the difference between past, present and future. But, according to Mahāyāna, any difference is engendered by afflictions and the true reality is free from them. Differences, including the difference between past, present and future, exist only in a saṃsāric consciousness. In other words, time for Mahāyāna is nothing more than an epistemological phenomenon. Time in Ad­vaita Vedānta has a positive ontological status. The only true reality is Brahman, and the empirical world is subject to changes and therefore cannot be considered as perfectly real. But if it were perfectly unreal it could not conceal Brahman and manifest itself in individual consciousness as ignorance. Therefore time as one of its aspects is only relatively real and exists not only in individual conscious­ness but also outside of it as a part of māyā, the creative power of Brahman. The overcoming of ignorance is the penetration to truly real Brahman through changing and temporary world that conceals it.

Mohists describe the relationship between the personal supreme deity (‘Heaven’) and ‘All Under Heaven’ as a relationship of the greatest and all-encompassing love, which distinguishes between good and bad and is always on the side of the first; which is ready to share its excess resources and opportunities with its creatures, but is also ready to judge and punish them if they oppose those whom it loves. The Daoist ideal of relations between the absolute impersonal first cause of the world (‘Way’) and its creations is opposite of this in many aspects: the ‘great love’ of the ‘Way’ is ‘a kin to no one’, it does not evaluate anything, does not desire anything, does not aspire to anything, knows nothing and judges no one. It allows everything to form itself freely, giving it an infinite space of possibilities. An assumption is made about the connection between the understanding of the first cause as personal or impersonal with the interpretation of the relationship between it and the universe as love or as an indifferent free-giving in ancient Chinese philosophy, in connection with which a proposal is made to check this on the material of the Confucian understanding of the relationship of the first cause to creatures as a promising continuation of the topic.
Problematizing the Idea of Eternal Hell Torments in Nikolai Berdyaev’s Philosophical Eschatology
Authors:   St. Tikhon’s Orthodox University, Antonov Konstantin
Published: January 2023

In the article based on the following works of N.A. Berdyaev: “The Destiny of Man. An Essay in Paradoxical Ethics”, “Creativity and Objectification. An Essay in Eschatological Metaphysics”, “Truth and Revelation. Prolegomena to the Criticism of Revelation”, and “Self-Knowledge: An Essay in Autobiography” the author analyzes the philosopher’s attitude to the idea of ‘eternal hell torments’. The author addresses the problems related to a rational reconstruction of Berdyaev’s thought, and argues for the possibility and necessity of philosophical discussion of theological problems. The relevant context for the development of Berdyaev’s thought on the topic is explicated, namely, the discourse on the problem of hell in Russian philosophy of the 19th and the early 20th centuries. It is demonstrated that if in “The Destiny of Man” Berdyaev points to the antinomian nature of the idea of hell and reproduces ‘the soul’s inner dialogue about hell’, distinguishing between the objective and subjective phrasing of the question, in the later works he gives a straightforward and systematic criticism of this concept, which includes several lines of argumentation: apologetic, psychological, historical-religious (that included speaking on the status of evangelical testimonies), sociological, ethical, and ontological. The author reconstructs the arguments proposed by Berdyaev along all of these lines and comes to the conclusion that, while completely rejecting the objective-ontological formulation of the issue of eternal hell torments, Berdyaev points to the reality of the existential experience of hell inherent in every person. The author concludes by summarizing the forms and aspects of the idea of hell, as considered in Berdyaev’s works, these are contrasted with the provisional results of modern discussions, and the need for theological understanding of Berdyaev’s interpretation of the idea of hell is indicated.

Trabalhar a Educação Cartográfica no contexto do ensino básico tem sido deveras desafiador. Em um mundo permeado pelas Novas Tecnologias da Informação e Comunicação (NTIC's), um dos grandes obstáculos a efetivação da aprendizagem em Cartografia pode ser encontrado em dar significado ao conteúdo e, consequentemente, capturar a atenção dos estudantes de modo a construir saberes e fazeres para sua prática cotidiana. É evidente que a sociedade, mesmo mergulhada em mapas e mapeamentos, pouco sabe e interage, porque este saber tem um grau de ‘cientificidade’, tendo pouca utilidade e significância na Geografia cotidiana. No bojo dessa peleja, velhos conhecidos surgem como novas ferramentas para o desenvolvimento de um ensino com maior eficácia e significância, como as práticas escolares de mapeamento colaborativo. Cabe salientar que, evocando a literatura sobre o ensino, temos na pesquisa dentro da educação básica uma centelha para a instigação da curiosidade dos alunos, o que permite o avanço para o próximo passo. A inserção do conhecimento cartográfico diversificado (aqui representado pelo mapeamento colaborativo feito a partir de mapeamentos efêmeros e/ou uso do geoprocessamento), a fim de saciar a sede de conhecimento dos estudantes e a fome de aprendizagem do docente (e porque não dizer também, das instâncias superiores de gestão educacional), tem permitido inserir mapas e processos de mapeamentos para debruçar-se sobre os processos sociais e territoriais. Partindo dessa conjectura, surgem os seguintes questionamentos: qual o papel das práticas escolares dos mapeamentos colaborativos para a transformação dos saberes cartográficos científicos em saberes cartográficos práticos e cotidianos? Pode-se proporcionar uma consciência cartográfica a partir das práticas escolares dos mapeamentos colaborativos? Para ilustrar a proposta aqui ensejada faremos uso de um conjunto de trabalhos realizados no interior cearense, mais precisamente em municípios da região do Cariri. Para além de ilustrar propõe-se uma discussão e avaliação acerca das práticas à luz das teorias cartográficas e do ensino de modo a deixar claro que não há de fato uma panaceia capaz de sanar todas as problemáticas do processo educativo da Cartografia. Todavia, há meios para construir saberes e fazeres que oportunize a prática de mapear para desvendar as tramas da(s) geografia(s) do(s) fenômenos que ocorrem no cotidiano, tornando-a mais prazerosa, eficaz e significativa.

Background: Daily exposure and overuse of digital devices are associated with several health-related issues to human eye, muscles and bones that are collectively termed as Digital Eye Strain and related Musculoskeletal Disorders. These problems have become worse during covid-19 pandemic due to global shift towards working online. This paper introduces a validated research instrument called DESRIL-27 to be used in assessing digital eye strain and related musculoskeletal disorders, with their associated risk factors in the working population.
Methods: DESRIL-27 was developed from thorough review of salient literatures and in consultation with a team of experts to ensure the content validity. This 27-item tool consists of two scales, namely symptom severity and risk level scales. Reliability and validity analyses were conducted to assess the psychometric properties of DESRIL-27.
Results: Cronbach’s alpha was 0.91 for Symptom Severity and 0.88 for Risk Level from the scales in the questionnaire. Principal Component Analysis results ranged from acceptable to very good.
Conclusions:The procedures adopted for the validation and the results of the analysis reveal that DESRIL-27 is a reliable and valid research instrument. It can be safely used in future research studies to assess the visual and musculoskeletal problems and their risk factors in digital screen users. The resultant knowledge can help individuals, health practitioners, and related policy makers to prevent and control these problems at workplace.

Published: January 2023

To address the unequal-area dynamic facility layout problem (UA-DFLP), an optimization method of dynamic facility layout under fixed-point movement strategy was proposed in this paper. Firstly, mathematical models of dynamic facility layout in several production planning period were constructed. Secondly, according to the logistics relationship between facilities, the fixed-point movement strategy was proposed to solve the problem of non-interference constraint processing in the unequal area dynamic facility layout. Then, a genetic simulated annealing algorithm (GSA) for static facility layout and a genetic algorithm (GA) for dynamic facility layout were designed to solve the UA-DFLP by two steps. The first step, the GSA was applied to solve the optimal layout in each phase with the objective of minimizing material handling cost (MHC), and the isomorphic layout corresponding to the optimal layout in each phase was evolved by mirroring and rotation operation; The second step, according to the optimal layout and feasible isomorphic layout of each phase, GA was applied to solve the dynamic layout scheme aiming at minimizing the sum of MHC and facility replacement cost. Finally, the case study shows that the proposed layout method was an effective method to solve the UA-DFLP by three groups of examples.
Primary large cell carcinoma of ureter ： a case report and review of the literature

Published: January 2023

Background：Neuroendocrine carcinoma mainly occurs in the lung and gastrointestinal tract, rarely in the urinary tract. The proportion of neuroendocrine carcinomas was less than 0.05 % [2] in urinary malignant tumors. The most common location of neuroendocrine carcinomas in the urinary system is the bladder. Fewer neuroendocrine carcinomas occur in the ureter than in the bladder.
Case presentation: A 62 years old woman presented with right ureteral obstruction due to ureteral mass. The patient began chemotherapy 2 weeks after surgery. During the 14-month follow-up, the patient received 6 courses of etoposide and Carbopol chemotherapy, and imaging examination showed no signs of recurrence. Postoperative pathological examination showed large cell neuroendocrine carcinoma of the right ureter.
Conclusions: Large cell carcinoma of ureter has a rapid course of disease and poor prognosis. Ureteral large cell carcinoma is a very rare tumor. At present, there is no specific treatment scheme. However, considering the good response of its lung counterpart to the standard chemotherapy scheme and the experience of the cure of related urinary large cell carcinoma by chemotherapy [28], we argue that platinum-based chemotherapy is effective for it and patients can benefit from it. The multimodal treatment scheme of surgery combined with platinum-based chemotherapy is the current standard scheme for the treatment of ureteral neuroendocrine carcinoma.
An Improved Adaptive Exponential Reaching Sliding Mode Control Strategy for Intelligent Connected Vehicle System under Complex Communication Environment and Different Types of Interference

Published: January 2023

This paper studies the performance of a nonlinear sliding mode controller in the cooperative control of the intelligent connected vehicles system. The study begins by proposing a V2V car-following model that takes into account the impacts of disturbances both external and within in the system. Subsequently, an improved adaptive exponential reaching sliding mode controller (IAERSMC) based on a non-singular terminal sliding mode variable is proposed. It is shown through theoretical analysis that with this controller, the system can converge in finite time and enhance dynamic performance. To verify the effectiveness of the controller proposed in this study, two simulation experiments are designed and performed. The first experiment tests the change of communication environment by transforming the communication topology, and the second experiment tests response to three different types of input interference: continuous regular interference, continuous irregular interference, and episodic disturbance. Simulation results show that the controller proposed in this study can maintain a stable operating state of the intelligent connected vehicles system in the face of the complex variable communication environments and different types of interference. The theoretical analysis agrees with the results of the simulated experiments.
