Juan Delgado, Francisco Ortega Delgado y el monumento de Semana Santa de la catedral ovetense (1731-1740): fulgores del barroco madrileño en provincias
Authors: González Santos Javier
Published: November 2021

La localización de una reproducción fotográfica del diseño original del monumento de Semana Santa de la catedral de Oviedo (en paradero desconocido desde 1924) nos permite trazar la historia de este desaparecido altar de perspectiva y bastidores pintados. Concebido por el pintor madrileño Francisco Ortega Delgado en 1732 y consagrado en 1740, fue destruido en 1903. La investigación desvela otros datos desconocidos, como la participación del pintor madrileño Juan Delgado en 1731 y el diseño de un altar gótico en 1903 para reemplazarlo.
Une critique de l’urbain depuis le champ des ambiances
Authors: Thomas Rachel
Published: November 2021

Cet article programmatique propose des pistes de travail pour élaborer une critique de l’urbain depuis le champ des ambiances. Si la critique n’est pas absente des travaux de ce champ, elle reste toutefois orientée en direction du champ de la conception auquel il est classiquement reproché de négliger les dimensions sensibles de l’espace. Une critique de l’urbain depuis le champ des ambiances aurait davantage pour enjeu de clarifier les enjeux sociétaux liés à la transformation programmée des ambiances urbaines. Quelle est la part des ambiances dans la mise en place de processus de normalisation des conduites urbaines ordinaires qui peuvent créer de la vulnérabilité, du trouble dans la civilité, voire des formes d’exclusion ? L’argument central du texte consiste à ouvrir le champ des ambiances à des interactions plus étroites avec la question du politique, principalement avec celle des formes de vie sensibles. Il s’agit de se questionner sur la manière de saisir du politique dans les ambiances - depuis des situations concrètes d’enquête et depuis leur généalogie - en décrivant, en questionnant et en appréciant leur transformation et leur poids dans l’épanouissement de manières d’être et d’être affectées plurielles (190 mots)

The enteric nervous system (ENS) is the third division of the autonomic autonomic nervous system and the largest collection of neurons outside the central nervous system (CNS). The ENS has been referred to as “the brain in the gut” or “the second brain of the human body” because of its highly integrated neural circuits controlling a vast repertoire of gut functions, including absorption/secretion, splanchnic blood vessels, some immunological aspects, intestinal epithelial barrier, and gastrointestinal (GI) motility. The latter function is the result of the ENS fine-tuning over smooth musculature, along with the contribution of other key cells, such as enteric glia (astrocyte like cells supporting and contributing to neuronal activity), interstitial cells of Cajal (the pacemaker cells of the GI tract involved in neuromuscular transmission), and enteroendocrine cells (releasing bioactive substances, which affect gut physiology). Any noxa insult perturbing the ENS complexity may determine a neuropathy with variable degree of neuro-muscular dysfunction. In this review, we aim to cover the most recent update on genetic mechanisms leading to enteric neuropathies ranging from Hirschsprung’s disease (characterized by lack of any enteric neurons in the gut wall) up to more generalized form of dysmotility such as chronic intestinal pseudo-obstruction (CIPO) with a significant reduction of enteric neurons. In this line, we will discuss the role of the RAD21 mutation, which we have demonstrated in a family whose affected members exhibited severe gut dysmotility. Other genes contributing to gut motility abnormalities will also be presented. In conclusion, the knowledge on the molecular mechanisms involved in enteric neuropathy may unveil strategies to better manage patients with neurogenic gut dysmotility and pave the way to targeted therapies.
Macroglossia reveals multiple myeloma
Authors: Bonvicini Maria , Crapanzano Davide , Fenu Susanna , Giordano Marco , Palleschi Lorenzo
Published: November 2021

We present an eighty-year old man with a one year history of progressive macroglossia, dysphagia and loss of weight. He had a medical history of arterial hypertension and prostatic hypertrophy which he had under good therapeutic control. The entire tongue was swollen, had hard solidity and was slightly painful upon palpation. A tongue biopsy revealed an amyloid deposition as it coloured bright orange-red on Congo Red staining and lead us subsequently to the diagnosis of amyloidosis; then a bone marrow biopsy confirmed the diagnosis of multiple myeloma. The case was further evaluated by a multidisciplinary team who considered it appropriate to start a lowdose melphalan treatment combined with supportive care. When macroglossia in the tongue is confirmed to be amyloidosis the differential diagnosis should include systemic amyloidosis deposition and multiple myeloma.

Published: November 2021

Background:

Parent–child relationship difficulties are seen in families of children and adolescents diagnosed with attention deficit hyperactivity disorder (ADHD), and they may contribute to long-term negative outcomes.

Aim:

Our aim was to examine perceived parenting and its correlation with emotional and behavioral problems in children and adolescents with a diagnosis of ADHD.

Materials and Methods:

This was a cross-sectional study involving 38 children and adolescents, between 8 and 16 years of age, diagnosed to have ADHD. Parents rated the children and adolescents on the Strengths and Difficulties Questionnaire (SDQ), whereas children/adolescents rated parents on the Alabama Parenting Questionnaire (APQ).

Results:

The study population primarily consisted of males (86.8%), between 8 and 12 years (68%), and belonged to urban families (82%). Warm, attentive, and engaged parenting behaviors which were subsumed under the domain of parental involvement in the APQ were associated with fewer total problem behaviors as well as specifically lower conduct and peer problems on the SDQ. Similarly, parents who used positive disciplining strategies as per the APQ had fewer total behavioral problems as well as specifically lower emotional problems on the SDQ. Children with comorbid oppositional defiant disorder reported lesser mean scores in all domains of parenting and significantly in the domains of parental involvement and positive parenting as per the APQ.

Conclusions:

Parental involvement and positive parenting were significantly associated with fewer emotional and behavioral problems in children and adolescents diagnosed with ADHD. This has direct implications for clinical practice. Further studies are needed to adapt parenting strategies to the Indian context.

It aims to provide the most up to date scientifically robust information on the topic published in the literature which has been critically analysed by an international group of clinicians drawn from all disciplines dealing with these problems together with patients. The guidelines offer evidence-based recommendations and care pathways for acute and chronic rhinosinusitis in both adults and children. Management of these diseases from the patients' perspective is an important part of EPOS2020. Not only is this included in the main document but, for the first time, we have produced a separate supplement dedicated to and in collaboration with patients, EPOS4Patients, which aims to provide information in an accessible format, to answer frequently asked questions about these diseases and their treatment options as well as including useful patient resources and websites. It has never been more important for patients to be actively involved in their care. Being well informed helps you to make the best decisions together with your doctor.
Culture Possibilities of Certain Brackishwater Species at Freshwater: A Climate Change Adaptation Strategy for Salinity Intrusion Prone Areas of Indian Sundarban Delta
Authors: Dubey Sourabh Kumar , Trivedi Raman Kumar , Chand Bimal Kinkar
Published: November 2021

Salinity intrusion into coastal mainland or freshwater habitat because of recent climatic changes is exacerbating production risks and challenging the coping capacity of freshwater fish farmers of Sundarban coastal delta in India. Hence, an experiment was conducted to evaluate the survival and growth performance of certain commercially important brackish water species in freshwater, and subsequent low salinities (5 g l−1 and 10 g l−1). Species like Scatophagus argus, Chelon parsia, Terapon jarbua, Etroplus suratensis, and Penaeus monodon showed the highest specific growth rate (SGR) at 10 g l-1 salinity. However, the growth rates were not differed significantly (P>0.05) compared to freshwater. Chelon planiceps and Mystus gulio exhibited the highest SGR at 5 g l-1 salinity, although growth rates of the fish were not differed significantly (P>0.05) with freshwater treatments. Comparable survival and growth of all species in the freshwater condition indicated their ability of healthy acclimation at freshwater ponds. Therefore, these euryhaline fish species can be promoted in the Indian Sundarban for culture in freshwater ponds as climate-resilient adaptation strategies. This study could be useful in decision making during species and farm site selection which eventually will minimize the risks from total crop loss during saltwater inundation.
Rearing of White Leg Shrimp Litopenaeus vannamei (Boone, 1931) in Biofloc and Substrate Systems: Microbial Community of Water, Growth and Immune Response of Shrimp
Authors: Chethurajupalli Lavanya , Tambireddy Neeraja
Published: November 2021

The microbial composition of rearing water, growth and immune status of Litopenaeus vannamei juveniles in biofloc (T1), substrate-integrated biofloc (T2), substrate (T3) systems and a control with four replicates each were evaluated in a 49-day indoor trail. In each HDPE tank of 70 L capacity filled with 10 g L-1 salinity water, ten shrimp (4.56±0.13 g) were stocked. The C: N ratio of 15:1 was maintained in T1 and T2 using wheat flour as carbon source for production of biofloc. The TAN, NO2 and NO3 were lower (P<0.05) in treatment tanks than that in control. It was also observed that the counts of Bacillus, Lactobacillus, Vibrio and zooplankton were high in T2 than T1, T3 and control. There was higher net weight gain (10.38±0.14 g) and lowest FCR (1.27±0.12) with T2 when compared to T1, T3 and control tanks. Moreover, the survival rate is significantly higher in treatments than control. Significant increase in THC (47.24±4.49 x 106 cells ml-1), serum protein (82.67±0.01 mg/ml), Phenoloxidase (0.73±0.03, OD 490 nm) and Lysozyme activity (56.32±0.03%) was observed in T2 than T1, T3 and control. The result shows that substrate-integrated biofloc system assures higher growth, survival and better immune response in L. vannamei.

Vključenost odraslih v izobraževanje v Sloveniji z mednarodno primerjavo
Authors: Čelebič Tanja
Published: November 2021

Avtorica v prispevku najprej prikazuje koristi, ki jih imajo posameznik, družba in gospodarstvo od izobraževanja. Bolje izobraženi imajo v povprečju v primerjavi s slabše izobraženimi višje osebne dohodke, stopnja tveganja revščine je pri njih nižja, izobraževanje pa pozitivno vpliva tudi na gospodarsko rast. Nato avtorica na osnovi razpoložljivih domačih in mednarodnih statističnih podatkov prikaže gibanje vpisa odraslih v izobraževanje v Sloveniji z mednarodno primerjavo z drugimi evropskimi državami in spreminjanje izobrazbene strukture odraslega prebivalstva v obdobju po letu 2000. Primerjava Slovenije z drugimi evropskimi državami in z evropskim povprečjem pokaže, da je vključenost odraslih v starosti od 25 do 64 let v vseživljenjsko učenje s 14,8 odstotkov v letu 2007 med najvišjimi med evropskimi državami in višja od omenjenega povprečja. Tudi vključenost odraslih v srednje in terciarno izobraževanje je višja od evropskega povprečja in se je v obdobju od 2000 do 2006 povečala. Izobrazbena struktura odraslega prebivalstva se postopoma izboljšuje. V obdobju od 2000 do 2007 se je zmanjšal delež prebivalstva s končano največ osnovno šolo in povečal se je delež prebivalstva s terciarno izobrazbo. Vključenost odraslih v starosti od 25 do 64 let v neformalno izobraževanje se je v obdobju od 2003 do 2007 malenkost povečala, v vključenosti kažejo velike razlike glede na doseženo izobrazbo. Kljub pozitivnim gibanjem v vključenosti pa sta razvojna izziva za v prihodnje povezana s spodbujanjem večje vključenosti starejših in nižje izobraženih v formalno in neformalno izobraževanje.

Fran Šturm. A cinquant'anni dalla scomparsa
Authors: Skubic Mitja
Published: November 2021

Il termine "scomparsa" del titolo non è, purtroppo, l'abituale eufemismo. Fran Šturm, il primo docente di filologia romanza presso la giovane Università di Ljubljana e, in quell'epoca, decano della Facoltà di Lettere, fu prelevato nella notte dal 12 al 13 marzo 1944 nella sua casa di Ljubljana da due sedicenti poliziotti in borghese, mai identificati (si era nel periodo dell' occupazione nazista), con la motivazione di un urgente confronto con un ufficiale partigiano catturato. Non fece mai ritomo a casa e vani furono i tentativi fatti dalla famiglia e dal rettore dell'Università presso le autorità militari tedesche e presso la polizia. Non si è mai saputo nulla, né è stato ritrovato e identificato dopo la guerra il suo cadavere. Tuttavia, un motivo c'era: lo Šturm era stato uno dei membri fondatori dell'OF (Fronte di Liberazione Nazionale) fin dall'occu­ pazione italiana della città nell' aprile del 1941 e lo smembramento della vecchia Jugoslavia, ed era 1'organizzatore della rete clandestina all'Università.
Usage labels network: an approach to lexical variation
Authors: Šipka Danko
Published: November 2021

The Problem of lexical variation is frequently addressed within the linguistic community. Its complexity and the broad implications of any possible solution have considerable appeal among theoretical linguists. Lexicographers, in their turn, have been forced to address it in order to provide dictionary usage information, which is normally done by means of dictionary labels such as: American English, obsolete, slang , etc. An insightful overview of the relevant lexicological approaches, as well as some lexicographis projects is provided in Lipka (1990). The most exhaustive sociolinguistic classification, however, can be found in Preston (1986). Lexicographis treatments of lexical variation have been addressed in numerous papers listed in Zgusta (1988).
Toponimi resiani in una stampa per liti della fine del Settecento
Authors: Matičetov Milko , Dapit Roberto
Published: November 2021

In fondo al libro di Aldo Madotto su La Val Resia ed i suoi abitanti, uscito a Udine/Mariano del Friuli durante l'estate 1982, si fa cenno a una raccolta di documenti resiani stesi dal 1382 al 1784 tra Moggio, Udine e Venezia, alcuni in latino, ma nella maggior parte in italiano. Si tratta di una stampa per liti "al taglio", che il compianto amico Aldo gentilmente mi aveva dato in visione, permettendomi così di trarne: 1) un breve (as)saggio Sulla "Lingua Illirica, o sia Reseana ", uscito nello stesso anno (Metodi e Ricerche, N.S., I, n. 2, Udine, 1982, pp. 94-95); 2) un esauriente elenco, fino ad oggi inedito, dei toponimi che nella raccolta di carte resiane 1382-1784 sono disseminati in grande quantità. Il fatto che alcune pagine della suddetta stampa siano già state presentate in facsimile dallo stesso Madotto (op.cit., 149-155), ci dispensa dal descriveme in questa sede l'aspetto esteriore, tuttavia riproduciamo in dimensione assai ridotta lo strano frontespizio della raccolta di documenti riuniti in un volume unico, fatto stampare (non è specificato né dove né quando) da una delle istanze attraverso le quali dovettero passare le cause nel loro iter giudiziario. Per fortuna, la data dell'ultimo degli atti inseriti nella pubblicazione ci consente di stabilire almeno il terminus ante quem non: 13 maggio 1784.

Vprašanje sloga v skladbah Jakoba Frančiška Zupana
Vprašanje slogovne opredelitve skladb – poskus njegove obravnave na primeru cerkvenih del Jakoba F. Zupana (I)
Authors: Škrjanc Radovan
Published: November 2021

Članek obsega prvi del avtorjevega razmisleka o vprašanjih, ki zadevajo slogovno klasificiranje skladb in – kot izhodišče obravnave teh vprašanj – povzema nekatere važnejše pomisleke glede primernosti opredelitve dveh cerkvenih del Jakoba Frančiška Zupana (1734–1810), Lavretanskih litanij in G in skladbe Te Deum laudamus, s slogovnima konceptoma barok in klasicizem. Dileme, ki se ob tem pojavljajo namreč ne tematizirajo le sprejemljivosti dosedanjih označitev skladateljevega Te Deuma za baročno in Litanij za klasicistično skladbo, glede na nekatere uveljavljene razvrstitve slogovnih značilnosti glasbenega baroka in klasicizma (npr. Blumejeve, v Epochen der Musikgeschichte iz leta 1974), temveč tudi nagovarjajo načelni premislek o konceptualnih izhodiščih epohnoslogovnega pristopa k zgodovini glasbe in zlasti posledicah nekritične aplikacije te vrste zgodovinopisne perspektive pri pisanju zgodovine glasbe »robnih območij« (M.

Published: November 2021

The objective of this study was to characterize a low cost heterogeneous catalyst from the transesterification of sand apple (Parinari polyandra B.) biodiesel. Sand apple fruits were processed and oil was extracted using solvent extraction method. Raw eggshells were calcined at 800°C for 120 min in the muffle furnace. Surface properties of the raw and calcined eggshell were characterized using Fourier Transformed Infrared Radiation (FTIR) and X-Ray Fluorescence (XRF). Transesterification of the Sand Apple Oil (SASO) with ethanol in the presence of the calcined catalyst to produce ethyl ester and glycerol were optimized using Central Composite Design at different temperatures and time. Reactants for the transesterification process were the raw SASO and anhydrous ethanol. The study shows that raw eggshell was more stable with hydrogen bond form at 2,724 cm-1an while oil yield of 53.13 % was obtained from sand apple kernels. Ethyl ester yield of 90% was obtained from SASO. The results of transesterification shows the maximum biodiesel yield of 90% was obtained at reaction temperature of 65°C and time of 120 min, while the minimum yield of 70% was obtained at temperature of 55°C and time of 60 min; indicating that biodiesel increase with increase in time. Similarly, yield of ethyl ester of SASO also increased when the reaction temperature increased. The percentages of biodiesel yield obtained from SASO transesterification in this study showed that sand apple is promising oil for biodiesel production as compared with other vegetable oil crop obtained in previous studies

Published: November 2021

Seafood and other environmental matrices are major entry route of harmful pollutants into humans due to constant contamination of the aquatic environment hence requires monitoring. This study scientifically explored the hypothesis that benthic gastropods bioaccumulate harmful pollutants that pose health risk to consumers of the sea food. Fifty samples of Thais coronata were collected per site from major regional fish landings. Two hundred samples were collected monthly for eight months to determine the concentrations of polycyclic aromatic hydrocarbon-PAH and possible health risks due to consumption using regulatory limits for guidance. Total PAH concentrations (μg/kg) varied between 65.68–173.52 suggesting differences in consumed concentrations at different times. The concentration of individual PAH congeners (1.376 ± 0.07-40.356±2.21 μg/kg) and PAH4 were below the European Union maximum limits. The Daily Dietary Intake values ranged from 0.075-2.212 μg/kg for individual PAH congeners while that of PAH4 was 1.359 μg/kg and were all below their respective reference oral doses. The carcinogenic potencies of the PAH congeners ranged from 0.001-143.389, the carcinogenic toxic equivalents (TEQs) of all PAH congeners was 0.1522 while that of PAH4 was 0.0044. The Excess cancer risk (ECR) value (10-8–10-5) was within USEPA guideline of 10-6 while the margin of exposure (MOE) of individual PAHs and PAH4 were higher than critical border line of 10,000 given by European Food Safety Authority but diagnostic ratio suggested PAH sources of pyrogenic origin in samples monitored. The study concluded low health risk for consumers of the shellfish (Thais coronata) in the study region but with recommendation advisory for regular monitoring to observe changes.
Geo-spatial Analysis of Land Use Land Cover (LULC) Changes in Oluwa Forest Reserve and its Environs

Published: November 2021

Mankind’s existence and modification of the landscape have had a profound effect on the natural environment. Anthropogenic activities such as agriculture, mining, deforestation and construction have influenced the shifting patterns of land use. This has resulted in a significant effect on local weather and climate. The use of remote sensing data in recent times has been of immense help in monitoring the changing pattern of vegetation. Therefore this study utilized remote sensing and geographic information system (GIS) methods to identify factors responsible for land use land cover (LULC) changes in Oluwa Forest Reserve between 1984 and 2017. The result showed that Primary forest was reduced by about 5% between 1984 and 2000 and by about 12% between 2000 and 2017 and the non-forest got increased by about 4% and 2% from 1984 to 2000 and from 2000 to 2017 respectively. Future forecast shows that primary forest will decrease by about 3% while the non-forest will increase by 5% by 2034. The results also revealed that the changes in forest cover between 2000 and 2017 were actively influenced by the closeness of settlements to the forest. It is therefore recommended that the findings of this study should be adopted by relevant authorities as a useful forest management tool.

Authors: Iroko O.A. , Sowunmi I.L. , Ajekiigbe J.M. , Rufiai S.O. , Wahab W.T.
Published: November 2021

Faidherbia albida is an agroforesrty tree that has the potential of promoting agroforestry establishment in Nigeria. The seeds are glossy due to the presence of wax in the seed coat which prevents easy penetration of water. Thus, this study assessed the effect of different pretreatments (biological, mechanical and chemical) on the germination of F. albida seeds. The treatments include; seeds scarified at the helium, soaked in cold water for 24 hours, soaked in hot water for 3 minutes, 5 minutes, 10 minutes, & 15 minutes and soaked in Conc. H2SO4 for 3 minutes, 5 minutes, 10 minutes, and 15 minutes. The result showed that all treatment had uniform germination percentage of 100% but seeds soaked in H2SO4 for 15 min and 10 min had the highest germination value of (65.25) and (65.00) respectively, followed by 15mins soaking in hot water (47.14) while the least germination value was recorded in seeds scarified mechanically (33.31). Analysis of variance revealed that there was no significant difference in the treatments. However, seeds treated with H2SO4 at 15 mins and 10 mins had the best performance in terms of germination value compared with other treatments. Therefore, for optimum and uniform germination, the seed of F. albida seeds should be soak in concentrated H2SO4 for 15 min.
Kinetic and Transesterification Properties of Lipase from Sprouted Melon (Cucumeropsis manni) Seeds
Authors: Osemwenkhae P.O. , Uadia P.O.
Published: November 2021

Crude lipase (acetone powder) was extracted from freshly sprouted melon seeds (Cucumeropsis manni). The activity, kinetic properties (effect of time, pH, and enzyme and substrate concentration, respectively) as well as the ability of the crude lipase to catalyze the production of methyl esters (biodiesel) were examined. The enzyme activity was determined using n-hexane as the solvent (1:2 v/w solvent: substrate ratio) and the transesterification product was analyzed by HPLC. A linear relationship was observed between reaction time and rate of lipolysis with the optimal activity at 2hr of incubation. Furthermore, the lipase was optimally active at acid pH 5 and lipolysis was achieved optimally when the amount of enzyme was 2.0g. Rate of lipolysis was observed to increase linearly at concentrations up to 5.0g of substrate above which a drop in the rate, with no apparent decrease in activity, was observed. The Km (6.25g) and Vmax (13.33%FFA/hr) were also determined. Analysis of the transesterification product yielded 0.61% alkyl ester, 0.81 %FFA, 93.17% TAG, 4.15% 1, 3-DAG and 1.26% 1, 2-DAG while transesterification efficiency was determined to be at 0.588%. Biodiesel (alkyl esters) prepared with the crude lipase was had a density of 0.872 g/mL while its cloud and pour points were 22°C and 12°C, respectively. The results from this research showed that an active lipase was isolated from sprouted melon seeds. However, the fuel properties of the biodiesel produced did not meet international transportation fuel standards. In order to be used industrially, better reaction conditions need to be established for the lipase.
Estimating Aboveground Biomass Using Allometric Models And Adaptive Learning Rate Optimization Algorithms
Authors: Okonkwo S.J. , Mshelia Z.H.
Published: November 2021

Forest aboveground biomass (AGB) is imperative in the study of climate change and the carbon cycle in the global terrestrial ecosystem. Developing a credible approach to estimate forest biomass and carbon stocks is essential. Four allometric models were used with two optimization algorithms; Modified Root Mean Square Propagation (Modified RMSProp) and Modified Adaptive Moment Estimation (Modified Adam) were also used to train each model. Convergence was achieved after 1000 iterations of Modified RMSProp and 200 iterations of Modified Adam for all the models. A learning rate of 0.01 and exponential decay rates of 0.9 and 0.999 for the first and second momentum. A loss function of 0.5 Mean Square Error (0.5 MSE) was used and Root Mean Square Error (RMSE) was used to judge the accuracy of the models. The study showed that the optimization algorithms were both able to accurately optimize three of the four allometric models. While Modified Adam was the more efficient optimizer, it had the highest RMSE value 2.3910 and Modified RMSProp had the least RMSE value 0.37381. However, there was no statistically significant difference between the accuracy of the models optimized by both algorithms.
Characterization and Investigation of Nonlinear Behaviour of Radio Refractivity during the Rainy and Dry Seasons in the Coastal Region of Nigeria
Authors: Adeniji A.E. , Ajeigbe E.M. , Ojo K.S.
Published: November 2021

The transmission and receiving of good quality of signals globally has been impaired due to the internal activities of the troposphere linked to the nonlinear behaviour of the meteorological parameters. This paper focusses on characterizing and investigating the nonlinear behaviour of radio refractivity during the rainy and dry seasons in the coastal region of Nigeria using temperature, pressure and relative humidity data collected over a period of two years by the Centre for Atmospheric Research, National Space Research and Development Agency (NASRDA) from Lagos state. Data obtained were analyzed by False Nearest Neighbour (FNN) and Recurrence Quantification Analysis (RQA). The results show that recurrence techniques are able to identify the periods where there are high predictability and low predictability. The investigation of nonlinear effects of meteorological parameters and the hydrometeors on the troposphere help to avoid fading of radio signals along with the radio communication links.
Controlling a random population
Authors: Colcombet Thomas , Fijalkow Nathanaël , Ohlmann Pierre
Published: November 2021

Bertrand et al. introduced a model of parameterised systems, where each agent
is represented by a finite state system, and studied the following control
problem: for any number of agents, does there exist a controller able to bring
all agents to a target state? They showed that the problem is decidable and
EXPTIME-complete in the adversarial setting, and posed as an open problem the
stochastic setting, where the agent is represented by a Markov decision
process. In this paper, we show that the stochastic control problem is
decidable. Our solution makes significant uses of well quasi orders, of the
max-flow min-cut theorem, and of the theory of regular cost functions. We
introduce an intermediate problem of independence interest called the
sequential flow problem and study its complexity.

Published: November 2021

En el presente artículo intento, en analogía con el trabajo de Lawrence Blum sobre el racismo, hacer un espacio conceptual y moral para lo que denominaré: “males sexo-generizados”. A diferencia del sexismo, el cual se define a partir de la inferiorización o la antipatía, los males sexo-generizados no incluyen estas condiciones. La ventaja de los males sexo-generizados es que permite una delimitación semántica y moral sobre fenómenos que podrían ser confundidos con el sexismo. Para ello repaso algunos casos como: a) la ignorancia e insensibilidad sexo-genérica, b) acciones afirmativas, c) socialización identitaria y d) privilegio masculino. Si bien estos casos suelen ser entendidos como sexistas debemos, por motivos conceptuales y morales, mantenerlos en la categoría de males sexo-generizados.

In the pathogenesis of the psoriatic disease, genetic and environmental factors play a significant role, and one of the most critical ecological influences is nutrition. At the same time, the influence of nutrition on the pathogenetic links of psoriasis is currently underestimated. The clinical guidelines for managing children and adults with psoriasis do not mention the need to consult a nutritionist and any dietary recommendations. The purpose of this literature review was to analyze current data on the role of various nutritional factors in the development of psoriatic disease, the pathogenesis of its complicated course, as well as the effectiveness of dietary interventions in the treatment of this category of patients. The analysis of sixty eight sources of literature has shown that dietary changes and the use of biologically active food supplements can have a specific effect on the complex therapy of the disease. The possibilities of diet therapy in patients with psoriasis and metabolic syndrome are also discussed. At the same time, it is evident that further research is needed to improve the evidence base for the effectiveness of nutritional methods in managing this category of patients, especially in paediatric-age patients.

Irrigation facilities is one of the key factors in farming, especially for food crop farming, including rice. A smallscale irrigation system has an area of less than 500 hectares, and it is the backbone of family food security which in turn will lead to national food security. Damage irrigation system networks will threaten food production increase. In the future, irrigation infrastructure must be better managed so that agricultural sector can realize agricultural diversification, conserve wider irrigation system and maintain local wisdom and social capital in irrigation management. The objective of the paper is to analyze performance, problems and solutions of small irrigation systems in Indonesia, including small irrigation concepts and understanding, small irrigation performance and development, small irrigation development policies, factors affecting smallscale irrigation development, investments, and prospects. The paper also compares various performances, problems and solutions of small irrigation systems in other countries. Small scale irrigation performance is often better than large-scale irrigation, in the sense of water availability throughout the year and equitable water distribution for all service areas

Renewable energy has been suggested as the primary approach for decarbonizing the energy system and decoupling energy consumption from greenhouse gas emissions, both in the energy literature and in practice. The European Union has acknowledged the challenge and put renewable energy transition high on the policy agenda with the latest ambition of being a carbon-neutral economy by 2050. On the other hand, Western Balkan countries are still dependent on fossil fuels as one of their primary energy mix sources. The pledge about the European future has mostly driven the renewable energy transition ambition in the Western Balkan countries, including Serbia. Moreover, signing the Energy Community Treaty provided institutional and legal tools to both Contracting Parties and the European Union to build the common energy market. These processes inspired many authors in the last two decades to analyse technical, economic, market and environmental aspects of renewables. However, the governance and planning, even though identified as challenging, have been side-lined from the analysis. This paper aims to overview the selected renewable energy transition literature and legislation to analyse the main legal and policy milestones reached so far, as well as ambition in Serbia. It also discusses the lessons learned from the related literature from energy governance and planning prism. To do so, it firstly provides a literature review of the main concepts of the renewable energy transition. Moreover, the historical analysis of renewable energy policy and legal developments in the European Union, the Energy Community and Serbia are in the second part's focus. Finally, the discussion part summarizes lessons learned from the literature for future energy governance and planning with the perspective of the energy planning process, policy evaluation, and education and administrative capacity. The article concludes by emphasizing the importance of taking the current literature findings as prospective steps to follow towards accelerated energy governance and planning.

By constructing bigger and bigger Data Centres (DCs), systems that make them become more complex. That leads to the requirement for the one common monitoring and management system that will monitor and manage functionalities for every individual element of the systems. In this paper, an overview of the systems that are implemented in tier 5 DC-s is given. Also, the roles of the systems are described. Special emphasis is on their own renewable energy sources (RES) and distribution switchgears that connect sources with Power System (PS) and DC. For quality monitoring of individual system elements parameter values and system in general, as well as the whole DC, it's necessary to design a unique database that contains information about defined parameter measurements. To make such database works, it is necessary to implement hardware that contains servers and data storage systems as the foundation on which a virtual platform is built. From all important elements of the systems, information is sent to centralized data base using a computer network. The system elements should contain network cards or controllers which role is to send measured values of the defined parameters to the main building in the format of Internet Protocol (IP) packets. In a suitable format, the data is displayed on the monitoring system. The same data are sent to the management system that manages the elements based on measured parameter values. This paper contains a proposition for the extension of existing monitoring and management system functionalities to the RES and distribution switchgear elements (DSE). Examples of practical usage of one non-commercial monitoring and management system are also given in the paper.

The paper will describe a multisectoral approach in development of long-term planning documents based on the example of developing background papers for low-carbon development strategy in the Republic of Croatia until 2030, with a view to the year 2050. As part of its obligations under the Regulation on the Governance of the Energy Union and Climate Action (EU 2018/1999), the Republic of Croatia is obliged to develop an Integrated National Energy and Climate Plan and a Long-Term Decarbonisation Strategy. New strategic goals of the Green Plan for Europe, intended to meet the goals of the Paris Agreement and raise global competitiveness of the European economy, set an ambitious goal of net zero greenhouse gas emissions by 2050. Fulfilling that vision requires a multidisciplinary approach as it does not suffice to reduce emissions from energy, industry, general consumption and transport, but it is necessary to increase removals in agricultural and LULUCF sectors. The paper will describe the development process, the engagement of numerous stakeholders, the methodological approach and the main outcomes. The analyses include detailed modelling in energetics, by economic sectors and natural carbon storage of the LULUCF sector. There are comments on synergistic energy challenges and on maintaining a secure food supply, as well as on sustainable forest management, achieving clean air, use of space and more.
Influence of Particular Design Parameters of Radial Guide Vane Cascades on Their Hydraulic Performance at Variable Speed Operated Francis Turbines
Authors:   “Ss. Cyril and Methodius” University in Skopje, Faculty of Mechanical Engineering, Stojkovski Filip , Markov Zoran
Published: November 2021

The design of radial blade cascades, with the intent to become turbine guide vanes, lies in the basis of satisfying turbine runner needs for a particular turbine design point of interest. For conventional turbine operation, the hydrodynamic parameters in the pre-runner space can be relatively easily estimated. For variable speed turbine operation at the constant head, these parameters change in a way that cannot be easily predicted using conventional techniques. In this paper, the guide vanes, as crucial turbine sub-system which needs to perform efficient runner flow feeding for these operating ranges, are numerically tested in various geometrical shapes and configurations, to observe the cascades behaviour, in a way of estimating which cascade configuration satisfies certain hydrodynamic and efficiency considerations of the operating points of interest. The criteria which the guide vanes need to meet are based on hydrodynamic parameters and expansion of the turbine operating range.

After the expiration of governmental incentive measures for renewable energy sources integration, economic feasibility of investing into solar power plants will highly depend on compatibility between production and variable prices. In order to achieve the maximum possible profit of the power plant in liberalized electricity market, it is necessary to consider the possibility of investing in solutions that are not common today, but with the potential of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed. It served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.
