    Abstract: A clamp-on ultrasonic transducer is disclosed. The clamp-on ultrasonic transducer comprises an ultrasound-propagating wedge having a first face and a second face which is inclined to the first face. The clamp-on ultrasonic transducer further comprises a first piezoelectric element which is mounted on the second face and which is directed obliquely at the first face. The wedge has a width, w, between first and second side walls, wherein the width, w, is less than or equal to 10 mm.

    Abstract: A flexural ultrasonic transducer is disclosed. The ultrasonic transducer comprises a sealed case which includes a flexible membrane and which defines a sealed cavity. The sealed case has an inside and an outside. The ultrasonic transducer comprises an active element, for example, a piezoelectric element, inside the sealed case supported on the flexible membrane. The ultrasonic transducer includes a liquid in the cavity. The sealed case includes a resilient portion between the inside and outside of the case for allowing equalization of pressure between the inside and the outside of the case. The resilient portion may comprise resilient walls or a thin-wall section, the flexible membrane or the case.

    Abstract: An embodiment provides a device for measuring pH in an aqueous sample, including: at least one measurement electrode comprising a first carbon region, wherein the carbon region comprises a single pH sensitive carbon region, wherein the single pH sensitive carbon region of the measurement electrode is a sp2 carbon region of a boron doped diamond-based pH electrode; at least one reference electrode; at least one auxiliary electrode; and a memory storing instructions executable by a processor to identify a pH of an aqueous sample by measuring an electrical potential between the at least one measurement electrode and the at least one reference electrode. Other aspects are described and claimed.

    Abstract: A method comprises the following steps: a) Providing a body having an internal surface which defines an internal pathway within the body, the body having an inlet and an outlet both communicating with the internal pathway; b) Introducing a liquid solution into the internal pathway so as to fill at least a portion of the internal pathway with the liquid solution, the liquid solution comprising a solute capable of undergoing thermal decomposition; c) Heating the liquid solution while the liquid solution fills said at least a portion of the internal pathway to a sufficient temperature so that the solute undergoes thermal decomposition to form a decomposition product within said at least a portion of the internal pathway. The heating step forms a coating comprising the decomposition product on at least a part of the internal surface that borders the internal pathway.

    IPC: A01N1/02

    Abstract: The present invention relates to a method for cryopreserving biological material. In particular, the method comprises storing the biological material at a cryopreserving temperature in a composition comprising polyvinyl alcohol (PVA), wherein the composition is substantially free of vitrification-inducing agents such as DMSO and glycerol. The invention also provides methods of inhibiting ice recrystallisation and of reducing cell damage during the warming or thawing of a cryopreserved composition comprising biological material. The invention also relates to processes for producing a biological material, and related kits.

    Abstract: A method, processor and system for controlling packet flow in a network provides for selecting a transmission scheme based on a payload rate for payloads arriving at a buffer. The transmission scheme includes data blocks comprising packets each having an associated payload, the data blocks have a variable packet transmission rate and a variable payload per packet ratio. The product of the variable packet transmission rate and the variable payload per packet ratio remains constant. The data blocks are sent to a network switch that deterministically routes the data blocks.
