Alpha-Amylase-Modified Cassava Starch in the Presence of Calcium Lactate as a Sour Starch Substitute for Gluten-Free Breadmaking [PDF]

Foods
Sour cassava starch is traditionally produced through spontaneous fermentation and solar drying, processes that induce molecular changes responsible for its high baking expansion but are difficult to standardize.

The hard ultraluminous state of NGC 5055 ULX X-1

Astronomy & Astrophysics
We present the results of the first broadband X-ray analysis of the ultraluminous X-ray source NGC 5055 ULX X-1, combining simultaneous data from XMM–Newton and NuSTAR missions, with a combined exposure time of ∼100 ks across the 0.3–20 keV energy range.

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Bimanual instrument suturing technique for periodontal and implant microsurgery: A technical note

Clinical Advances in Periodontics, EarlyView.
Abstract Background In the traditional suturing technique, the dominant hand (DH) holds a needle holder, and the non‐dominant hand (NH) performs manual ties without the aid of an instrument. In periodontal and implant microsurgery, finer sutures and needles, e.g., 7‐0 in International Organization for Standardization units, are used, which could be ...

Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

Geological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...
