Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Requeijão da Beira Baixa is a boundary entry, set by heat, not by microbes. Sheep and goat whey left from the three Beira Baixa PDO cheeses is strained, heated to 80–90 °C with slow stirring until flakes float up, then the heat is lowered and stirring stopped for 15–30 minutes, until just before boiling. The flakes are ladled into small wicker or plastic baskets and presented as a fresh, unfermented product.
Amounts from a sourceThe single document gives no batch size or recipe beyond the limit that water and milk together are at most 10 % of the whey volume. Each piece weighs 150–400 g.
Sheep and goat whey from making the Beira Baixa PDO cheeses
Strained to remove the remains of the curd[rbb-sd2013]
Raw sheep or goat milk and potable water from the production areaWater and milk together up to 10 % of the total volume of the whey used
Water is added if salt forms in the milk; a small amount of sheep or goat milk is usually added just before boiling to get a larger, thicker mass[rbb-sd2013]

Requeijão da Beira Baixa is a boundary entry, set by heat, not by microbes. Sheep and goat whey left from the three Beira Baixa PDO cheeses is strained, heated to 80–90 °C with slow stirring until flakes float up, then the heat is lowered and stirring stopped for 15–30 minutes, until just before boiling. The flakes are ladled into small wicker or plastic baskets and presented as a fresh, unfermented product. Made in 5 steps over 15 min – 30 min. The longest step, let the flakes rise, takes 15–30 min (European Commission 2013).
Made only from the whey of the three Beira Baixa PDO cheeses and drained into small wicker or plastic baskets that leave a truncated cone with a criss-cross pattern.
Size
Truncated cone with a basket pattern, 150–400 g
Composition
Moisture 60–70 %; fat 14–19 g, protein 10–13 g and ash 1.4–1.8 g per 100 g
A storage study at 4 °C found no bacteria (under 10 CFU/g) on the day of making, but high counts of Bacillus, Pseudomonas, Enterobacteriaceae and lactic acid bacteria after storage, packed or not. Vacuum packing, with the acid that built up under it, held back yeasts, staphylococci, enterococci and spore-forming clostridia (Pintado and Malcata 2000). The single document allows packing only in the production area, and allows vacuum packing.
Hazards the sources name: Staphylococci and spore-forming clostridia (held back by vacuum packing in the same study); Enterobacteriaceae, which reached high counts in stored requeijão, packed or not, in the same study.
