The article discusses the earliest, mostly lost works known only through archival photographs, and the early preserved works by Rudolf Valdec (8 March 1872, Krapina – 1 February 1929, Zagreb) who, apart from RobertFrangeš-Mihanović, was Croatia’s first modern sculptor. These works were created upon Valdec’s return from studying at Vienna and Munich, in the period between 1896 to 1898, that is, prior to the exhibition CroatianSalon where they were displayed. The findings about his earliest, previously unknown, works have been gathered through research in archives and old journal articles which mention them. At the same time, Valdec’s early works are not only well-known but famous, for example the relief Love, the Sister of Death (Ljubav sestra smrti, 1897), Magdalena (1898) and Memento Mori (1898). These reliefs and sculptures in the round demonstrate Valdec’s skill in sculptoral modelling and provide evidence that he was a sculptor of good technical knowledge andcraftsmanship. They also show the thoroughness of his education at Vienna’s K. K. Kunstgewerbeschule des Österreichischen Museums für Kunst und Industrie where he studied under Professor August Kühne, and at the Königliche Bayerische Akademie der bildenden Künste in Munich where he was supervised by Professor Syrius Eberle. It is difficult to follow Rudolf Valdec’s continuity as a sculptor because his student works have not been preserved and neither have some of the earliest works he made when he returned to Zagreb. Only a small number of previously unknown or unpublished photographs have been found which show the works which have been irretrievably lost. These works of unknowndimensions were not signed and are therefore considered as preparatory studies for more large-scale works from the earliest phase of his career. These are the reliefs of Apollo made for the pediments of the Pavilion of the Arts (Umjetnički paviljon) at Zagreb which was designed by Floris Korb and Kálmán Giergl, the Hungarian historicist architects, to house the Croatian displays at the Millenial Exhibition at Budapest in 1896. A year later, in 1897, the iron frame of the pavilion was transported to Zagreb.The bid to carry out the work was won by the Viennese architects Herman Helmer and Ferdinand Fellner, but the actual construction was done by the Zagreb architects Leo Hönisberg and Julio Deutsch under thesupervision of the city’s engineer Milan Lenuci. Valdec was entrusted with the making of reliefs illustrating the hymn to Apollo (Apollo of Delphi, Apollo Pythoctonos, and Apollo Musagetes). These three bas-reliefs werenever affixed to the pediments of the Pavilion of the Arts because the City Council did not authorize the execution due to a lack of funds. However, they were displayed at the Millenial Exhibition at Budapest and the Croatian Salon in 1898, and contemporary critics praised them as successful works of the young Valdec. The first relief depicts the Apollo of Delphi (hymn to Apollo) holding a severed head in his raised left hand. The second relief depicts Apollo Musagetes next to a shoot of a laurel tree(the symbol of Daphne) with a lyre in his left hand. The third relief shows Apollo Pythoctonos who, in a dynamic movement, is stringing his silver bow and shooting an arrow into the gaping mouth of a fire-breathing dragon.In his youth, Valdec produced works which embodied fear, anxiety, pessimism, restlessness and bitterness, all corresponding to the general tendencies of the fin de siècle. In 1899 he made Pessimism (Pesimizam), a work only known through its mention in the press by the critic M. Nikolić. Many other youthful works from the period between 1885 to 1889 have also been lost. These were: Passion, Christ, and Love (Muka, Krist, and Ljubav, 1896-1896) which were displayed at the Millenial Exhibitionin Budapest, Altar of the Saviour (Spasiteljev žrtvenik), Lucifer, Per Aspera ad Astra, Kiss (Cjelov), Christ Salvator (Krist Salvator), Hymn to Apollo (Apolonova himna), Apollo Phoebus (Apolon Phoebus), Ridi Pagliaccio, and Jesus (Isus). Our research has yielded photographs of theworks Per Aspera ad Astra and Christ Salvator, both of 1898. All the work from his youthful phase is in the Art Nouveau style, in harmony with the dominant stylistic trends in Vienna, Munich and central Europe, which,unsurprisingly, attracted Valdec too. In his desire to express his feelings and spiritual condition, as can be seen in the works like Per Aspera ad Astra, Valdec reveals the stamp of the Art Nouveau symbolism.Although Valdec’s earliest and a number of his early works have mostly been lost, those that have been preserved are made of plaster and bronze (now at the Collection of Plaster Casts of the Croatian Academy ofArts and Sciences in Zagreb), and belong to the most significant works of Croatian modern sculpture. The works in question are the relief sculptures Love, the Sister of Death (1897), Memento Mori (1898) and Magdalena(1898). The relief Love, the Sister of Death represents the first example of symbolism and stylization which were a novelty in modern sculpture in Croatia. The relief of Magdalena is, regardless of the fierce criticism on account of its nudity published by the priest S. Korenić in Glas koncila, a master-piece not only because it represents an excellent nude but also because of the psychological and philosophical expression it radiates. It is one of the best reliefs in Croatian sculpture in general. The relief Memento Mori features the first and only example of Valdec’s self-portrait rendered in profile, in which he depicted himself as a fool. The busts of Plato (Platon) and Aristotle (Aristotel) are considered to be first portraitscommissioned by Iso Kršnjavi. They were made in 1898 and set up on the wings of the building which housed the seat of the Department of Theology and Teaching in 10 Opatička Street, at the head of which was Kršnjavi. Valdec made the busts of these two Greek philosophers in the style of Roman naturalistic portraits.

SummaryThe anti-aggregating activity of five rising doses of clopidogrel has been compared to that of ticlopidine in atherosclerotic patients. The aim of this study was to determine the dose of clopidogrel which should be tested in a large scale clinical trial of secondary prevention of ischemic events in patients suffering from vascular manifestations of atherosclerosis [CAPRIE (Clopidogrel vs Aspirin in Patients at Risk of Ischemic Events) trial]. A multicenter study involving 9 haematological laboratories and 29 clinical centers was set up. One hundred and fifty ambulatory patients were randomized into one of the seven following groups: clopidogrel at doses of 10, 25, 50,75 or 100 mg OD, ticlopidine 250 mg BID or placebo. ADP and collagen-induced platelet aggregation tests were performed before starting treatment and after 7 and 28 days. Bleeding time was performed on days 0 and 28. Patients were seen on days 0, 7 and 28 to check the clinical and biological tolerability of the treatment. Clopidogrel exerted a dose-related inhibition of ADP-induced platelet aggregation and bleeding time prolongation. In the presence of ADP (5 \lM) this inhibition ranged between 29% and 44% in comparison to pretreatment values. The bleeding times were prolonged by 1.5 to 1.7 times. These effects were non significantly different from those produced by ticlopidine. The clinical tolerability was good or fair in 97.5% of the patients. No haematological adverse events were recorded. These results allowed the selection of 75 mg once a day to evaluate and compare the antithrombotic activity of clopidogrel to that of aspirin in the CAPRIE trial.

Results of the basic model configuration of the REMO project, a Brazilian approach towards operational oceanography, are discussed. This configuration consists basically of a high-resolution eddy-resolving, 1/12 degree model for the Metarea V, nested in a medium-resolution eddy-permitting, 1/4 degree model of the Atlantic Ocean. These simulations performed with HYCOM model, aim for: a) creating a basic set-up for implementation of assimilation techniques leading to ocean prediction; b) the development of hydrodynamics bases for environmental studies; c) providing boundary conditions for regional domains with increased resolution. The 1/4 degree simulation was able to simulate realistic equatorial and south Atlantic large scale circulation, both the wind-driven and the thermohaline components. The high resolution simulation was able to generate mesoscale and represent well the variability pattern within the Metarea V domain. The BC mean transport values were well represented in the southwestern region (between Vitória-Trinidade sea mount and 29S), in contrast to higher latitudes (higher than 30S) where it was slightly underestimated. Important issues for the simulation of the South Atlantic with high resolution are discussed, like the ideal place for boundaries, improvements in the bathymetric representation and the control of bias SST, by the introducing of a small surface relaxation. In order to make a preliminary assessment of the model behavior when submitted to data assimilation, the Cooper & Haines (1996) method was used to extrapolate SSH anomalies fields to deeper layers every 7 days, with encouraging results.

This paper focuses on the effects of the off-design operation of CAES on the dynamic characteristics of the triple-gear-rotor system. A finite element model of the system is set up with unbalanced excitations, torque load excitations, and backlash which lead to variations of tooth contact status. An experiment is carried out to verify the accuracy of the mathematical model. The results show that when the system is subjected to large-scale torque load lifting at a high rotating speed, it has two stages of relatively strong periodicity when the torque load is light, and of chaotic when the torque load is heavy, with the transition between the two states being relatively quick and violent. The analysis of the three-dimensional acceleration spectrum and the meshing force shows that the variation in the meshing state and the fluctuation of the meshing force is the basic reasons for the variation in the system response with the torque load. In addition, the three rotors in the triple-gear-rotor system studied show a strong similarity in the meshing states and meshing force fluctuations, which result in the similarity in the dynamic responses of the three rotors.

Seagrass planting techniques have shown to be an effective tool for restoring degraded meadows and ecosystem function. In the Mediterranean Sea, most restoration efforts have been addressed to the endemic seagrass Posidonia oceanica, but cost-benefit analyses have shown unpromising results. This study aimed at evaluating the effectiveness of environmental engineering techniques generally employed in terrestrial systems to restore the P. oceanica meadows: two different restoration efforts were considered, either exploring non-degradable mats or, for the first time, degradable mats. Both of them provided encouraging results, as the loss of transplanting plots was null or very low and the survival of cuttings stabilized to about 50%. Data collected are to be considered positive as the survived cuttings are enough to allow the future spread of the patches. The utilized techniques provided a cost-effective restoration tool likely affordable for large-scale projects, as the methods allowed to set up a wide bottom surface to restore in a relatively short time without any particular expensive device. Moreover, the mats, comparing with other anchoring methods, enhanced the colonization of other organisms such as macroalgae and sessile invertebrates, contributing to generate a natural habitat.

AbstractThe COVID-19 pandemic caused by SARS-COV-2 virus fortunately resulted in few children suffering from severe disease. However, the collateral effects on the COVID-19 pandemic appear to have had significant detrimental effects on children affected and young people. There are also some positive impacts in the form of reduced prevalence of viral bronchiolitis. The new strain of SARS-COV-2 identified recently in the UK appears to have increased transmissibility to children. However, there are no large vaccine trials set up in children to evaluate safety and efficacy. In this short communication, we review the collateral effects of COVID-19 pandemic in children and young people. We highlight the need for urgent strategies to mitigate the risks to children due to the COVID-19 pandemic. What is Known:• Children and young people account for <2% of all COVID-19 hospital admissions• The collateral impact of COVID-19 pandemic on children and young people is devastating• Significant reduction in influenza and respiratory syncytial virus (RSV) infection in the southern hemisphere What is New:• The public health measures to reduce COVID-19 infection may have also resulted in near elimination of influenza and RSV infections across the globe• A COVID-19 vaccine has been licensed for adults. However, large scale vaccine studies are yet to be initiated although there is emerging evidence of the new SARS-COV-2 strain spreading more rapidly though young people.• Children and young people continue to bear the collateral effects of COVID-19 pandemic

Abstract Population rise, climate change, soil degradation, water scarcity, and food security require efficient and sustainable food production. Aquaponics is a highly efficient way of farming and is becoming increasingly popular. However, large scale aquaponics still lack stability, standardization and proof of economical profitability. The EU-INAPRO project helps to overcome these limitations by introducing digitization, enhanced technology, and developing standardized modular scalable solutions and demonstrating the viability of large aquaponics. INAPRO is based on an innovation a double water recirculation system (DRAPS), one for fish, and the other one for crops. In DRAPS, optimum conditions can be set up individually for fish and crops to increase productivity of both. Moreover, the integration of digital technologies and data management in the aquaculture production and processing systems will enable full traceability and transparency in the processes, increasing consumers’ trust in aquaculture products. In this paper, the innovations and the digitization approach will be introduced and explained and the key benefits of the system will be emphasized.

Photographs of the German and Soviet pavilions facing off at the Paris International Exposition in 1937 offer an iconic image of the interwar period, and with good reason. This image captures the interwar period's great conflict of ideologies, the international interconnectedness of the age and the aestheticisation of political and ideological conflict in the age of mass media and mass spectacle. [Figure 1] Last but not least, it captures the importance in the 1930s of what we now call cultural diplomacy. Both pavilions – Germany's, in Albert Speer's neo-classical tower bloc crowned with a giant swastika, and the Soviet Union's, housed in Boris Iofan's forward-thrusting structure topped by Vera Mukhina's monumental sculptural group – represented the outcome of a large-scale collaboration between political leaders and architects, artists, intellectuals and graphic and industrial designers seeking to present their country to foreign visitors in a manner designed to advance the country's interests in the international arena. Each pavilion, that is, made an outreach that was diplomatic – in the sense that it sought to mediate between distinct polities – using means that were cultural – in the sense that they deployed refined aesthetic practices (like the arts and architecture) and in the sense that they highlighted the distinctive features, or ‘culture’, of a particular group (like the German nation or the Soviet state).

AbstractThe low-redshift Lyα forest of absorption lines provides a probe of large-scale baryonic structures in the intergalactic medium, some of which may be remnants of physical conditions set up during the epoch of galaxy formation. We discuss our recent Hubble Space Telescope (HST) observations and interpretation of low-z Lyα clouds toward nearby Seyferts and QSOs, including their frequency, space density, estimated mass, association with galaxies, and contribution to Ωb. Our HST/GHRS detections of ∼ 70 Lyα absorbers with Nhi ≥ 1012·6 cm−2 along 11 sightlines covering pathlength Δ(cz) = 114,000 km s−1 show f (>Nhi) α Nhi−0·63±0·04 and a line frequency dN/dz = 200 ± 40 for Nhi > 1012·6 cm−2 (one every 1500 km s−1 of redshift). A group of strong absorbers toward PKS 2155–304 may be associated with gas (400–800) kpc from four large galaxies, with low metallicity (≤0·003 solar) and D/H ≤ 2 × 10−4. At low-z, we derive a metagalactic ionising radiation field from AGN of J0 = × 10−23 erg cm−2 s−1 Hz−1 sr−1 and a Lyα-forest baryon density Ωb =(0·008 ± 0·004)[J−23N14b100]½ for clouds of characteristic size b = (100 kpc)b100.

Development process in Odisha (before 2011 Orissa) may have led to progress but has also resulted in large-scale dispossession of land, homesteads, forests and also denial of livelihood and human rights. In Odisha as the requirements of development increase, the arena of contestation between the state/corporate entities and the people has correspondingly multiplied because the paradigm of contemporary model of growth is not sustainable and leads to irreparable ecological/environmental costs. It has engendered many people’s movements. Struggles in rural Odisha have increasingly focused on proactively stopping of projects, mining, forcible land, forest and water acquisition fallouts from government/corporate sector. Contemporaneously, such people’s movements are happening in Kashipur, Kalinga Nagar, Jagatsinghpur, Lanjigarh, etc. They have not gained much success in achieving their objectives. However, the people’s movement of Baliapal in Odisha is acknowledged as a success. It stopped the central and state governments from bulldozing resistance to set up a National Missile Testing Range in an agriculturally rich area in the mid-1980s by displacing some lakhs of people of their land, homesteads, agricultural production, forests and entitlements. A sustained struggle for 12 years against the state by using Gandhian methods of peaceful civil disobedience movement ultimately won and the government was forced to abandon its project. As uneven growth strategies sharpen, the threats to people’s human rights, natural resources, ecology and subsistence are deepening. Peaceful and non-violent protest movements like Baliapal may be emulated in the years ahead.

Despite the massive demand of water for plant irrigation, there are few devices being used in the automation of this process in agriculture. This work evaluates a simple controller to water plants automatically that can be set up with low cost commercial materials, which are large-scale produced. This controller is composed by a ceramic capsule used in common domestic water filters; a plastic tube around 1.5 m long, and a pressostate used in domestic washing machines. The capsule and the pressostate are connected through the tube so that all parts are filled with water. The ceramic capsule is the sensor of the controller and has to be placed into the plant substrate. The pressostate has to be placed below the sensor and the lower it is, the higher is the water tension to start the irrigation, since the lower is the pressostate the higher is the water column above it and, therefore, the higher is the tension inside the ceramic cup to pull up the water column. The controller was evaluated in the control of drip irrigation for small containers filled with commercial organic substrate or soil. Linear regressions explained the relationship between the position of pressostate and the maximum water tension in the commercial substrate (p < 0.0054) and soil (p < 0.0001). Among the positions of the pressostate from 0.30 to 0.90 m below the sensor, the water tension changed from 1 to 8 kPa for commercial substrate and 4 to 13 kPa for the soil. This simple controller can be useful to grow plants, applying water automatically in function of the water tension of the plant substrate.
