cucinaremale (“badcooking” or “cookingbadly”) is an Italian Facebook group created in 2014 which now (February 2020) counts more than 126,000 members. It was conceived to let members post their everyday culinary disasters and amusingly show solidarity with each other, while struggling in a cruel world where — as the official description suggests — everybody seems to have become a professional cook, capable of distinguishing even the different types of salt on the market: “Enough with this craze for cooking: hurray for pre-cooked food!”. The article proposes an analysis of the culinary ideologies at stake and a typology of the textual practices carried out by the cattivicuochi (“badcooks”). cucinaremale provides a true manifesto against the global food craze better known as gastromania — a true cacogastromania (“bad gastromania” or “mania for the bad food”).

Pollination plays a significant role in the agriculture sector and serves as a basic pillar for crop production. Plants depend on vectors to move pollen, which can include water, wind, and animal pollinators like bats, moths, hoverflies, birds, bees, butterflies, wasps, thrips, and beetles. Cultivated plants are typically pollinated by animals. Animal-based pollination contributes to 30% of global food production, and bee-pollinated crops contribute to approximately one-third of the total human dietary supply. Bees are considered significant pollinators due to their effectiveness and wide availability. Bee pollination provides excellent value to crop quality and quantity, improving global economic and dietary outcomes. This review highlights the role played by bee pollination, which influences the economy, and enlists the different types of bees and other insects associated with pollination.

Breeding Techniques

Abstract Background The broadness of biotechnology serves to connect different types of modern plant breeding techniques with the potential to improve global food security. However, the topic goes beyond the specific example consumers’ associate with the term—genetic modification. As a result, it is often unclear if consumers really know what they claim to understand and the efforts to clarify the science and reasoning behind the use of these practices is often obscured. Methods Two online surveys of 500 Canadians were conducted in 2017. Results Three-quarters of Canadians have high levels of trust in those who provide information about food, yet two-thirds believe that modern plant breeding technologies are unnatural. Conclusions Canadians lack basic knowledge about modern plant breeding practices and technologies and possess high levels of uncertainty regarding the potential for benefits or externalities to develop from the commercialization of new genome editing plant breeding technologies.

This article is devoted to the study of the impact of gender discrimination on malnutrition in the world, which has not lost its relevance for many years. The aim of the work is to identify the correlation between the level of tension of the global food problem and the degree of involvement of women in all spheres of human life, in particular the economy, on an equal basis with men. To achieve this goal, the authors identified the factors that contribute to world hunger, of which gender discrimination as an issue unresolved over decades was analyzed. In order to understand the importance of the gender issue, the paper presents facts and indicators that show that in many countries of the world the gap in rights between men and women actually exists. Without denying the possibility of the existence of the individual cases of gender discrimination against men, the authors consider women as the discriminated party. The work demonstrates women's contribution to world food security and identifies the limitations associated with different types of discrimination that prevent women from realizing their potential in this regard. Possible cases for both male and female gender were studied as well as cases related exclusively to women's physiological features.

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Complete Interpretation

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.

Different Types

In polyethylene single crystals pairs of black and white lines spaced 700-3,000Å apart, parallel to the [100] and [010] directions, have been identified as microsector boundaries. A microsector is formed when the plane of chain folding changes over a small distance within a polymer crystal. In order for the different types of folds to accommodate at the boundary between the 2 fold domains, a staggering along the chain direction and a rotation of the chains in the plane of the boundary occurs. The black-white contrast from a microsector boundary can be explained in terms of these chain rotations. We demonstrate that microsectors can terminate within the crystal and interpret the observed terminal strain contrast in terms of a screw dislocation dipole model.

Fibers composed of different types of collagen cannot be differentiated by conventional electron microscopic stains. We are developing staining procedures aimed at identifying collagen fibers of different types.Pt(Gly-L-Met)Cl binds specifically to sulfur-containing amino acids. Different collagens have methionine (met) residues at somewhat different positions. A good correspondence has been reported between known met positions and Pt(GLM) bands in rat Type I SLS (collagen aggregates in which molecules lie adjacent to each other in exact register). We have confirmed this relationship in Type III collagen SLS (Fig. 1).

Investigation of the particulate matter contained in the water sample, revealed the presence of a number of different types and certain of these were selected for analysis.An A.E.I. Corinth electron microscope was modified to accept a Kevex Si (Li) detector. To allow for existing instruments to be readily modified, this was kept to a minimum. An additional port is machined in the specimen region to accept the detector, with the liquid nitrogen cooling dewar conveniently housed in the left hand cupboard adjacent to the microscope column. Since background radiation leads to loss in the sensitivity of the instrument, great care has been taken to reduce this effect by screening and manufacturing components that are near the specimen from material of low atomic number. To change from normal transmission imaging to X-ray analysis, the special 4-position specimen rod is inserted through the normal specimen airlock.
