Specific Orientation

When foraging, animals combine internal cues and sensory input from their environment to guide sequences of behavioral actions. Drosophila larva executes crawls, turns, and pauses to explore the substrate and find food sources. This exploration has to be flexible in the face of changes in the quality of food so that larvae feed in patches with favorable food and look for another source when the current location does not fulfill their nutritional needs. But which behavioral elements adapt, and what triggers those changes remain elusive. Using experiments and modeling, we investigate the foraging behavior of larvae in homogeneous environments with different food types and in environments where the food sources are patchy. Our work indicates that the speed of larval crawling and frequency of pauses is modulated by the food quality. Interestingly, we found that the genetic dimorphism in the foraging gene influences the exploratory behavior only when larvae crawl on yeast patches. While in a homogeneous substrate larvae maintain a turning bias in a specific orientation, in a patchy substrate larvae orient themselves towards the food when the patch border is reached. Therefore, by adapting different elements in their foraging behavior, larvae either increase the time inside nutritious food patches or continue exploring the substrate in less nutritious environments.

External Reasons

The global crisis that hit the world economy at the end of the first decade of the 21st century has significantly affected Russia. Since 2014 and up until now, due to internal and external reasons, there has been an almost continuous decline in real disposable income of Russian households. Many Russian families are forced to economize down to the essentials. As is generally known, food costs are at the very bottom of Maslow’s hierarchy of needs, and their reduction occurs in the last place. However, within this primary segment of consumption negative processes also occur; in determining the structure of costs the choice is cast over the quality of food and in favour of its affordability. Faced with the fall of its turnover, even large retail chains brands are forced to improve their pricing strategies in order to stabilize their falling revenues in the face of increasing competition. “How can they achieve this?” is the question the authors of two articles in this series attempt to answer. The first article examines problems associated with development of “customer loyalty programs”, and proposes a model for improving the existing system of trade margins. The article also looks at the advantages and limitations of the proposed model.

Working Parameters

The aim of this investigation was analysis of main mixing-distribution trailer working parameters. This will serve as a base for evaluation of possibilities for obtaining better feed preparation quality on farms, more uniform feed distribution, higher productivity and energy saving. Results have shown that different conceptions of mixing-distribution trailers have different quality of food distribution. Best uniformity of distribution was achieved by using of trailer with horizontal mixing rotor and with tiller for silage cutting and loading.

Abstract Background Large scale public investment in Public Distribution System (PDS) have aimed to reduce poverty and malnutrition in India. The PDS is the largest ever welfare programme which provides subsidised food grain to the poor households. This study attempt to examine the extent of stunting and underweight among the children from poor and non-poor households by use of public distribution system (PDS) in India. Methods Data from the National Family and Health Survey-4 (NFHS-4), was used for the analysis. A composite variable based on asset deprivation and possession of welfare card provided under PDS (BPL card), was computed for all households and categorised into four mutually exclusive groups, namely real poor, excluded poor, privileged non-poor and non-poor. Real poor are those economically poor and have a welfare card, excluded poor are those economically poor and do not have welfare card, privileged poor are those economically non-poor but have welfare card, and non-poor are those who are not economically poor and do not have welfare card. Estimates of stunting and underweight were provided by these four categories. Descriptive statistics and logistic regression were used for the analysis. Results About half of the children from each real poor and excluded poor, two-fifths among privileged non-poor and less than one-third among non-poor households were stunted in India. Controlling for socio-economic and demographic covariates, the adjusted odds ratio of being stunted among real poor was 1.42 [95% CI: 1.38, 1.46], 1.43 [95% CI: 1.39, 1.47], among excluded poor and 1.15 [95% CI: 1.12, 1.18], among privileged non-poor. The pattern was similar for underweight and held true in most of the states of India. Conclusions Undernutrition among children from poor households those excluded from PDS is highest, and it warrants inclusion in PDS. Improving the quality of food grains and widening food basket in PDS is recommended for reduction in level of malnutrition in India.

The ability of pumpkin pies as prepared and distributed in the food distribution system to support growth of selected food pathogens was studied. Products were puchased from a cross-section of retail outlets. Microbial quality of the products was determined. One of four samples contained high levels of coliforms and Staphylococcus aureus. Salmonella was not detected in any of the samples. Samples were inoculated with Salmonella typhimurium and S. aureus and incubated at 4, 25 and 35 C. Water activity (aw), pH and S. aureus enterotoxin were measured. Pumpkin pies supported growth of the pathogens at 25 and 35 C. Data revealed if contaminated and held at room temperature, pumpkin pies could present a public health hazard. Growth of pathogens is inhibited at refrigeration temperatures. Enterotoxin was present in samples containing S. aureus. Potassium sorbate (0.25%) inhibited growth of S. typhimurium but not S. aureus. Refrigeration is recommended for pumpkin pies to eliminate the possible health hazard.

«Man is what he eats,» these words belong to the great Pythagoras. He meant by these words the connection of the origin of consumed food with the spiritual development of man. In fact, a lot depends on the nature of nutrition, the quality of food and, of course, on the degree of its perception by the body. Digestion process begins not in the stomach, but directly in the oral cavity as a result of mechanical processing of products with teeth and under the influence of the secretion of the salivary glands. That is why healthy teeth are the key to the normal functioning of the whole organism — people should start taking care of their teeth from the early childhood and dentists, who are far from being beloved by everybody and are often carelessly evaded, are called upon to help keep the teeth healthy.
