Physicochemical properties and quality parameters of herbhoneys

Herbhoney is a honey-like substance produced by bees fed on a saccharose-based food supplemented with herbal extracts or fruit juices. Having specific sensory characteristics (colour, aroma and taste), different from those of natural honeys, herbhoneys greatly extend the range of bee products. With the aim of improving the knowledge of herbhoneys of various origins, their chosen physicochemical and quality parameters were evaluated. It was found that the herbhoneys studied satisfied most of the requirements relative to natural honeys (water, hydroxymethylfurfural and saccharose contents, free acidity, and diastase number). Some of the samples showed an increased specific conductivity, characteristic of honeydew honeys, although the ash contents of herbhoneys were at a level typical of nectar honeys. The saccharose content of some herbhoneys exceeded the value allowed for most natural honeys. Mineral composition varied between the samples, being in most cases within the limits reported in this literature for natural honeys.     

The cognitive-behavioral relationship record.

The Cognitive-Behavioral Relationship Record is a technique designed to help individual psychotherapy clients make sense of chronic relationship problems and to encourage them to experiment with new behavioral solutions. In this paper, the reader is given step-by-step instructions on how to use the Relationship Record accompanied by case illustrations. By conceptualizing relationships in terms of the interplay between two individuals’ cognitions and behaviors, the Relationship Record gives therapists a new tool to address the circular causality in relationship systems. In addition to its usefulness as a therapeutic technique, it may be seen as a step toward the integration of family systems into cognitive–behavioral therapy, or, more specifically, the assimilation of strategic therapy techniques and concepts into Aaron T. Beck’s school of cognitive therapy. The Relationship Record joins a movement in psychotherapy integration to enhance individual-based therapies by assimilating interpersonal approaches.

The crystal structures of three azonaphtharylamide pigments

The single crystal X-ray structures of three structurally related azonaphtharylamide pigments are reported. Two azo pigments derived from 4-amino-3-nitrotoluene as diazo component (1a and b) crystallize in the centrosymmetric space group P2₁/c while the third (1c), an analogue of 1b but derived from 2,5-dichloroaniline as diazo component, crystallizes in the chiral space group P2₁2₁2₁. The compounds adopt the ketohydrazone tautomeric forms with intramolecular, but no intermolecular, hydrogen bonding. The application performance of the products is discussed in relation to the molecular and crystal structures. X-ray powder diffraction, supported by FTIR spectroscopic and DSC analysis, demonstrate that pigment 1a shows polymorphism. The application performances of the two polymorphs of this pigment are compared.     

Transient behavior of run-around heat and moisture exchanger system. Part IІ: Sensitivity studies for a range of initial conditions

Part І of this paper [17] developed and verified the numerical model for simultaneous heat and moisture transfer in the run-around membrane energy exchanger (RAMEE) system to determine the transient behavior of the system under different initial and operating conditions.This paper presents the transient response of the RAMEE system for step changes in the inlet supply air temperature and humidity ratio. Also the system quasi-steady state operating conditions are predicted as the system approaches its asymptotic operating condition. The transient responses are predicted with changes in various parameters. These include: the number of heat transfer units, thermal capacity ratio, heat loss/gain ratio, storage volume ratio and the normalized initial salt solution concentration. It is shown that the storage volume ratio and the initial salt solution concentration have significant impacts on the transient response of the system and heat transfer between the RAMEE system and the surrounding environment can change the system quasi-steady conditions substantially.     

Gravity and solidity in four great ape species (Gorilla gorilla, Pongo pygmaeus, Pan troglodytes, Pan paniscus): Vertical and horizontal variations of the table task.

Three experiments modeled after infant studies were run on four great ape species (Gorilla gorilla, Pongo pygmaeus, Pan troglodytes, Pan paniscus) to investigate their reasoning about solidity and gravity constraints. The aims were: (a) to find out if great apes are subject to gravity biased search or display sensitivity for object solidity, (b) to check for species differences, and (c) to assess if a gravity hypothesis or more parsimonious explanations best account for failures observed. Results indicate that great apes, unlike monkeys, show no reliable gravity bias, that ape species slightly differ in terms of their performance, and that the errors made are best explained by a gravity account.

Volatile profile of Stilton cheeses: Differences between zones within a cheese and dairies

Penicillium roqueforti grows and sporulates during the ripening period of blue cheeses and it is responsible for the typical blue cheese flavour formation. However, the sporulation (blue veins) is taking place in a fraction of the total mass and the cheese matrix is highly heterogeneous. The aroma profiles regarding the three different sections of Stilton cheese, blue veins outer crust and white core, were studied using solvent extraction GC–MS, a headspace GC–MS technique (SPME GC–MS) and direct headspace analysis (APCI–MS). Cheeses from different dairies were analysed, allowing the question of how similar are different batches of cheese from different dairies.     

Automatic reconstruction of as-built building information models from laser-scanned point clouds: A review of related techniques

Building information models (BIMs) are maturing as a new paradigm for storing and exchanging knowledge about a facility. BIMs constructed from a CAD model do not generally capture details of a facility as it was actually built. Laser scanners can be used to capture dense 3D measurements of a facility's as-built condition and the resulting point cloud can be manually processed to create an as-built BIM — a time-consuming, subjective, and error-prone process that could benefit significantly from automation. This article surveys techniques developed in civil engineering and computer science that can be utilized to automate the process of creating as-built BIMs. We sub-divide the overall process into three core operations: geometric modeling, object recognition, and object relationship modeling. We survey the state-of-the-art methods for each operation and discuss their potential application to automated as-built BIM creation. We also outline the main methods used by these algorithms for representing knowledge about shape, identity, and relationships. In addition, we formalize the possible variations of the overall as-built BIM creation problem and outline performance evaluation measures for comparing as-built BIM creation algorithms and tracking progress of the field. Finally, we identify and discuss technology gaps that need to be addressed in future research.
