The sixteenth-century find “Treatise On Land Surveying Methods Using the Surveyor’s Cross”, by Francesco Paciotti, military and civil architect to the Duchy of Urbino: the technical evolution of a surveying tool.
No full textThis paper focusses on the autograph Treatise “On land surveying methods using the surveyor’s cross” found at the Biblioteca Umanistica dell’Università degli Studi di Urbino “Carlo Bo” (“Carlo Bo” Urbino University Humanistic Library). The treatise was for many years erroneously included among the writings of the Urbino mathematician Muzio Oddi (1569-1639), author of Dello Squadro (On the Surveyor’s Cross) of 1625, but through careful bibliographic research has now been attributed to the civil and military architect Francesco Paciotti, (1521-1591). Paciotti’s important knowledge of mathematics and geometry applied to the erection of fortifications and land measurement was essential, too, in the design of an innovative kind of a new surveyor’s cross, which was able to provide more accurate topographic measurements and land surveys. Paciotti extolled the tool as being essential for architecture, and almost certainly used it to build the Citadel of Turin, which provided the model for the construction of all other European citadels and fortresses. The Paciotti’s treatise provides the restorer with a wealth of knowledge on the materials and executive technique used to manufacture the tool

Nutritional features of organic peas (Pisum sativum L.) cultivated in different Italian environments and rheological profile of pea‐enriched crackers
Full text linkBACKGROUND: Legumes are a key component of the human diet and a primary source of plant-based protein. They have attracted global attention as potential plant-based meat alternatives due to their numerous health benefits, and they contribute to a more sustainable and healthy food system. Among pulses, peas (Pisum sativum L.) are considered a good source of proteins, fibers, starch, minerals, and vitamins. This study evaluated the effect of environmental conditions on nutritional profile of peas cultivated in an organic farming system, in different Italian environments (mountainous and hilly), during different cultivation years (2021 and 2022). Pea grain from peas cultivated under the various conditions was used to prepare pea-based crackers containing 6% pea flour. The appearance, physical properties (rheology and texture), and nutritional profile of the snacks were evaluated, and sensory analysis was conducted. RESULTS: The nutritional and bioactive compounds were strongly related and the environment exerted a substantial impact on most of the nutritional components (proteins and carbohydrates), due to climatic conditions during the vegetative and reproductive stage of the crop. The incorporation of cultivated peas into wheat-based crackers improved their functional and nutritional quality while maintaining consumer acceptability, as demonstrated by sensory analysis. CONCLUSIONS: The results confirmed that growing conditions significantly influence the nutritional composition of peas, enhancing their quality and that of the resulting crackers. This aligns with the increasing global demand for high-quality, sustainable food products. © 2025 The Author(s).

Full text linkGodine 1941. u Nastavnome vjesniku hrvatski filozof, jezikoslovac i leksikograf Kruno Krstić objavio je u dva nastavka neveliku raspravu pod naslovom Problem prvih podataka u znanosti. Pojedina pitanja koja Krstić u toj raspravi razmatra, zadiru u nekoliko različitih filozofskih područja: dotiču se naime u isti mah kako logike i epistemologije, tako filozofije znanosti i filozofije jezika. U prilogu se ponajprije ističe važnost problema o kojem je riječ, a potom se razmatraju različiti vidici pod kojima Krstić tomu problemu pristupa. Posebice se raspravlja o Krstićevoj raščlambi nekih pojmova koji se često, osobito na razini tzv. »naivne« svijesti, smatraju posve samorazumljivima (kao što su, primjerice, pojmovi osjetilnosti, iskustva, objektivnosti, apstrakcije, pa i sam pojam činjenice). Također se naglašuje Krstićev zanimljiv pogled na pojedine smjerove u povijesti filozofije (racionalizam, empirizam, senzualizam). Na kraju se upozorava i na novost koju je Krstić unio u tadašnju hrvatsku filozofiju, vidljivu i u ovoj njegovoj raspravi, naime na činjenicu da je filozofskim pitanjima rado pristupao kroz prizmu jezika, postavivši tako analizu značenja u središte svoga filozofiranja.The Nastavni vjesnik (Teachers News) published in 1941 the two sequels of a smallish treatise entitled The Problem of First Data in Science by the Croatian philosopher, linguist, and lexicographer Kruno Krstić. Several of the issues under discussion in the treatise involve various philosophical disciplines: logic and epistemology, philosophy of science and philosophy of language. The paper first stresses the im portance of the discussed problem, and then analyzes the various ways in which Krstić deals with the problem. In particular, the author discusses Krstić's analysis of certain notions which are often, especially at the level of the so-called »naive« awareness, considered to be self-evident (as, for instance, the notions of sense, experience, objectivity, abstraction, and the very notion of fact). The author also stresses Krstić's interesting view of particular doctrines in the history of philosophy (rationalism, empirism, sensualism). Finally, the author points at the novelty Krstić introduced in the then Croatian philosophy, evident in the mentioned treatise, namely the fact that he used to approach philosophical issues viewed through the prism of language, placing the analysis of meaning into the center of his philosophy
Effects of Crop Management Systems On Weed Abundance and Soil Seed Bank
No full textGiven the importance of different weed management systems (MS) for weed communities and soil seed bank, our aim was to study the impacts of organic (Org) and conventional (Conv) MS in tomato and sugar beet on the abundance of weeds and weed seed bank. The results have shown that in both crops the aboveground weed flora is dominated by 2–3 species in the Conv MS, while it is more diverse in the Org MS. In both crops the soil seed bank is less diverse when compared with the aboveground weed flora. Furthermore, a comparative analysis of the weed flora and soil seed bank has shown a high number of different weed seeds in the soil for tomato, unlike sugar beet, where a higher number of weeds was determined in the aboveground weed flora. In tomato, the soil seed bank is more diverse in Org MS (4.1 ± 1.5) than in Conv MS (3.8 ± 1.3), which was also true for the aboveground plant biodiversity (4.6 ± 1.1 vs. 3.6 ± 1.5 species, respectively). Also, although the differences in aboveground weed density and abundance in tomato were not statistically significant, seed bank reserves in the Org MS were significantly more abundant (40.4 ± 16.7 weed seeds vs. 4.5 ± 3.6 in Conv MS). This study has also shown that in sugar beet there were practically no differences between Org and Conv MS, even though the abundance of its aboveground weed flora was higher in Org MS (70.2 ± 29.4 vs. 38.1 ± 21.2 plants/m2 in Conv MS). In conclusion, it can be said that although both MS had similar effects on weed management in tomato, for sugar beet Org MS has proven to be less effective in weed control. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Deutschland, part of Springer Nature
Comparison of 2 weight-based heparin dosing nomograms in neurology and vascular surgical patients
No full textUnfractionated heparin sodium (UFH) is used in neurology and vascular surgical patients to treat and prevent thromboembolic occlusions and requires weight-based dosing to achieve a therapeutic range; however, the optimal dosing strategy is not known. This study sought to determine whether an intravenous (IV) weight-based UFH dosing nomogram based on an 80-unit/kg bolus and 18-unit · kg(-1) · h(-1) initial infusion rate achieves therapeutic anticoagulation [activated partial thromboplastin time (aPTT), 65-110 seconds] more rapidly than that based on a 60-unit/kg bolus and 12-unit · kg(-1) · h(-1) initial infusion rate in 98 neurology and vascular surgery patients.The study consisted of a retrospective chart review of adults prescribed and administered IV UFH for >6 hours, admitted under the neurology or vascular surgery teams and administered UFH for transient ischemic attack, stroke, acute ischemic limb, or postoperative revascularization.The time to therapeutic aPTT analysis showed superiority of the higher dose (P = 0.04, log-rank test). At 6 hours, there was a significantly greater proportion of patients within the therapeutic range in the higher dose group (36.0% versus 16.7%, P = 0.03), with fewer subtherapeutic aPTTs (34.0% versus 70.8%, P < 0.001) and more supratherapeutic aPTTs (30.0% versus 12.5%, P = 0.034).A weight-based nomogram for IV UFH using an 80-unit/kg bolus and an initial infusion rate of 18 units · kg(-1) · h(-1) showed a more rapid achievement of therapeutic aPTT when compared with a 60:12 dosing nomogram. Future research assessing a 70-unit/kg bolus dose is recommended
