Strategies for Building the Revolutionary Left
Authors: Lamusse Ti
Published: March 2020

This paper outlines some potential strategies for growing revolutionary left organisations in Aotearoa, using the case study of People Against Prisons Aotearoa (PAPA), previously known as No Pride in Prisons. Lamusse provides a brief history of PAPA and outlines their experiences organising with the prison abolitionist organisation since its founding, sharing the lessons they learned about growing revolutionary left organisations in Aotearoa. They argue that to ensure democracy, transparency, and a fair division of labour, left organisations need clearly defined decision-making structures and roles. They demonstrate how, since PAPA transformed from a structureless organisation, it has not only become more democratic, but has also become a far more effective movement.

Technological features of thick-film electric heating elements
Authors: Telnikov Ye.Ya. , Chernyshyn O.G.
Published: March 2020

The article deals with the technical parameters of thick-film heating elements, the peculiarities of their operation, as well as the scope of use in household and industrial heat-generating electrical devices.
The world is constantly researching the possibility of developing heating elements without the aforementioned disadvantages of tube thermal elements, which allow more efficient use of consumed electricity, which leads to significant savings. A new type of heat to heat converter is proposed in this direction. The use of this converter - the heating element - in various industrial and household products can save up to 30% of electricity consumption.
At the heart of the design of the heating element is a developed system of different properties of composite nanostructured materials - pastes. On the basis of this system of materials the technology of production of new heating elements with unique properties was created. The heating element is made by screen printing (silk screening) of special composite materials on a dielectric or metal substrate with their subsequent heat treatment. Dielectric, resistive, dielectric layers are sequentially applied to a flat substrate of any configuration, but can also be applied to cylindrical surfaces.
Purposeful formation of a conductive structure in the resistive layers of thick-film heating elements and the ability to influence the properties of the nanoscale layer between the particles of the conductive phase allowed to create a group of materials, and on their basis, a series of heating elements with the properties of the technical intellect, environment. The technology for production of heating elements with self-regulation of parameters for wide values of supply voltage, thermal power, and specific heat dissipation power (surface heat flux density) has been developed.
One of the significant advantages of the technology is the absence in the resistive paste of expensive and scarce precious metals and their compounds, which are part of similar pastes, offered by leading manufacturers in the world. Due to this, the cost of manufacturing such pastes is substantially lower than that of the world.

Published: March 2020

The article presents the technological potential research results of secondary resources
formed in the King crab cutting process for food purposes. The authors analyzed waste
(cephalothorax and abdomen) obtained from the King crab industrial processing from the
North Okhotsk sea subzone and Primorye subzone. They determined the size and mass
characteristics of waste. There is the shell, viscera (including liver), gills and abdominals ratio.
A man examined the ratio of mineral (shell) and protein (interior and gills) parts of the studied waste experimentally. The research aim was to determine the total chemical composition, amino acid composition of proteins, fatty acid composition of lipids and mineral composition of the combined waste. The authors revealed that the secondary raw materials
under the experiment consisted of the protein by 13.37 ± 0.05 %, lipids by 2.68 ± 0.1 %,
minerals by 8.33 ± 0.25 % and carbohydrate compounds by 4.22 ± 0.05 %. The experiment
determined the essential amino acids sum in the protein part. Valine, leucine and cysteine
are limiting. Fatty acids in lipids waste are represented by polyunsaturated fatty acids in
significant amounts (42.11 %). Calcium and sodium are overwhelming macronutrients in
the waste from the King crab cutting, while iron and zinc are dominating microelements.
The research results indicate the high technological value of waste from King crab cutting
and the potential of this secondary raw material as a basis for the production of biologically
valuable protein and mineral products.

Published: March 2020

The article reveals the recipes and technologies development issues of berry sauces with
lactulose for catering enterprises differing in functional orientation. Nowadays there is
a need of sauces development using berries of the Ural region and lactulose due to the
deficiency of many vitamins, minerals and other biologically active nutrients in the human
diet, as well as the relevance to maintain the gastrointestinal tract microbiocenosis. The
study was based on the assortment analysis results of berry sauces produced by public
catering enterprises and the consumer preferences data. The results demonstrated that
frozen and dried raw materials of foreign manufacturers were the main raw materials in
the berry sauces production at the enterprises. This led to a decrease in nutritional value,
organoleptic properties deterioration and an increase in the finished products cost. The
researchers developed five recipes of sauces with using berries of the Ural region origin
as the main raw material on the comparison basis of real, ideal and simulated consumer
properties profiles of berry sauces according to the standard recipes including the main
stages of the General concept of berry sauces production. They determined the optimal
combinations and ratios of the introduced raw materials components considering the
organoleptic quality indicators. The authors developed preparation technologies of new
berry sauces types (defined stages of the components introduction and the main operations,
and technological parameters); presented its description and technological scheme.
A man tailored a point scale for evaluating organoleptic indicators of berry sauces quality
to examine the quality of new berry sauces types; calculated nutritional value and mass
fraction of dry substances in berry sauces. Obtained results indicate a high level of developed
products quality. The researchers concluded that the sauces use of berries growing
in the Ural region in the manufacture can reduce the berry sauces cost while increasing its
nutritional value.

Published: March 2020

Tropical fruit jackfruit is becoming increasingly popular in the world and in Russia. In the
Russian and European food markets jackfruit is mostly present as dried fruit. For the rational
choice of the technological equipment and energy calculations of drying units the
authors determined and presented empirically structural, mechanical and thermophysical
properties of jackfruit in a graphical and mathematical interpretation depending on the
influencing factors, but not only its characteristics such as moisture content, cell structure,
the vapor-gas medium presence filling the pore space during dehydration, which determined
the method and regime parameters of moisture removal. The experiment aim
was to study, systematize and generalize the structural, mechanical and thermophysical
characteristics of the research object for further scientific kinetics and dynamics analysis
of heat and mass transfer processing procedure, its mathematical modeling and solving
rationalization problems of the drying process. The researchers used the complex thermophysical
characteristics determination method of a viscous liquid, pasty and particulate
materials based on heart and inertia properties of the thermocouple to calculate the thermal
conductivity coefficient λ, indicators of thermal diffusivity α and specific heat capacity
cM of the experimental material during its heat treatment. The article presents the following:
the graphic interpretation in the temperature range of 273÷363 K and humidity from
0.2 to 0.73 kg/kg depended on the true jackfruit slices density ρi (in this case, the jackfruit
mass density is reliant on the chemical composition and mainly on moisture content and
dry matter); the approximated interpretation of the specific heat capacity dependence
of jackfruit slices; the conductivity graph of the sample slices; and other materials. The
research results are experimentally and analytically determined thermophysical characteristics
and physical density of jackfruit slices in the given ranges of humidity and coolant
parameters, on which the choice of a rational method and drying mode of the material
depends.

Inhibitory effects of Armillaria mellea (Vahl) P. Kumm. on liver glutathione S-transferase activity
Authors: KÜTÜK Ayşegül , SADİ Gökhan
Published: March 2020

Armillaria mellea (Vahl) P. Kumm. commonly-known as the honey fungus is an edible mushroom and its antioxidant, antitumor, neuroprotective, and insulin resistance reductive effects have been well-characterized. Glutathione S-transferases (GST) are the group of detoxification enzymes has a function to conjugate glutathione to the variety of electrophile, making them more water-soluble for excretion. Their inhibition or activation could have profound toxicological or clinical implications. This study is conducted to investigate the inhibitory effects of A. mellea on GST enzymes. Total GST activities were measured using glutathione and 1 chloro-2,4-dinitrobenzene as substrates spectrophotometrically, and enzyme kinetic studies were conducted to determine Vmax and Km values. Additionally, aqueous and methanolic extracts of A. mellea were tested to see how they modulate the kinetic parameters. Vmax for liver GST enzyme was calculated as 443.90 ±11.52 U/mg, Km value for GSH, and CDNB were determined as 4.88± 0.53 mM and 10.43±1.07 mM, respectively. The decrease in Vmax and the increase in Km values with A. mellea extracts demonstrated a mixed-type inhibitory mechanism. Methanolic extract inhibits the GSH-dependent GST activity much more than the CDNB-dependent activity, but aqueous extract mainly affects CDNB-dependent GST activity. In conclusion, A. mellea could suppress the hepatic GST enzymes that might have toxicological consequences such as reduced cellular detoxification of electrophilic xenobiotics as well as alleviated drug resistance in the treatment of several diseases.

The Effects of Writing on Learning in Science, Social Studies, and Mathematics: A Meta-Analysis
Authors: Graham Steve , Kiuhara Sharlene A. , MacKay Meade
Published: March 2020

This meta-analysis examined if students writing about content material in science, social studies, and mathematics facilitated learning ( k = 56 experiments). Studies in this review were true or quasi-experiments (with pretests), written in English, and conducted with students in Grades 1 to 12 in which the writing-to-learn activity was part of instruction. Studies were not included if the control condition used writing to support learning (except when treatment students spent more time engaging in writing-to-learn activities), study attrition exceeded 20%, instructional time and content coverage differed between treatment and control conditions, pretest scores approached ceiling levels, letter grades were the learning outcome, and students attended a special school for students with disabilities. As predicted, writing about content reliably enhanced learning (effect size = 0.30). It was equally effective at improving learning in science, social studies, and mathematics as well as the learning of elementary, middle, and high school students. Writing-to-learn effects were not moderated by the features of writing activities, instruction, or assessment. Furthermore, variability in obtained effects were not related to features of study quality. Directions for future research and implications for practice are provided.
Climate Services for Agricultural and Livestock Producers: What have we learned?
Authors: Breuer Norman , Fraisse Clyde William
Published: March 2020

Climate services are scientifically based products that enhance users’ understanding on the impacts of climate on their decisions and actions. Decision Support Systems (DSSs) are programs that use models and other information to make site-specific recommendations for farm management-related activities. Climate variability is a source of production risk worldwide and is associated with other risks such as pest and disease incidence. Extreme climate events such as drought, intense precipitations, and pest or disease outbreak can also affect commodity prices and increase marketing risk. However, climate forecasts alone usually do not provide actionable information for improving decisions and policy. Climate forecasts are the basis for co-development of DSSs to support improved decisions at different scales to maximize profits and input use, and to minimize climate risks, and negative environmental externalities. Major advances in developing DSSs occurred through design, diffusion, and adoption made possible through continuous interaction among scientists, boundary organizations and end users in a participatory research and development process. This article describes the evolution of this process and addresses issues of co-development, participation, scale, and future research needs through a case study that highlights commonalities and differences between producer needs, perceptions, and adoption at two research sites (one in Florida, USA and the other in southeastern Paraguay).
