Food availability and the male's role in parental care in double-brooded TreecreepersCerthia familiaris

1996

The aim of this work was to examine differences in paternal and maternal care in a double-brooded, monogamous species, the Treecreeper Certhia familiaris, in relation to food availability. As a measure of parental care, we recorded the hourly feeding activity of parents when the nestlings from their first and second breeding attempts were 7 and 12 days old. Feeding frequency of the first brood increased with the age of the nestlings and also with the brood size when 12 days old. While the feeding activities of the females were similar with respect to the first and second broods, the males were less active and failed to provide any food to their nestlings in 15 cases out of 28 second broods.…

Effect of Vibration on the Quality of Strawberry Fruits Caused by Simulated Transport

2015

Mechanical damage of agricultural products is one of the main problems in the harvest and postharvest chain due to the large economic loss that the shelf life reduction could generate. Measurements of change in the chemical components of highly perishable products and microbial growth under different static and dynamic loads is the first step in the development of intelligent logistic units that could help in predicting the residual shelf life in order to minimize losses along the supply chain. In our research, the effects of vibration along the supply chain of a case study were analyzed on strawberry (Fragaria × ananassa) and woodland strawberry (Fragaria vesca) in terms of microbiological…

Interaction of dietary polyphenols and gut microbiota: Microbial metabolism of polyphenols, influence on the gut microbiota, and implications on host…

2020

Abstract The human gastrointestinal tract is inhabited by a vast number of microorganisms that are called as the microbiota. Each individual harbors a unique gut microbial composition, this composition evolves throughout the host's lifetime and it is easily affected by internal or external changes. It has been shown that gut microbiota plays a crucial role in host's health and as this complex community has the ability to interact with each other and with the host's immune system, the presence or absence of some major species can affect the homeostasis. Diet can be considered as one of the pivotal factors in modulating the functionality, integrity, and composition of the gut microbiota as th…

Alternative Ways of Energy Supply in Rural Areas

2019

Optimization of thermal energy and electricity production processes using renewable energy source (RES) is extremely important for agricultural horticultural, and production farms. The article is devoted to the search for the best available techniques to the optimize the process of obtaining heat energy from RES to meet the energy needs in Polish agriculture. The food industry is particularly energy-intensive and as a result, when introducing various innovative technological processes, strong emphasis is placed on rational energy consumption and minimizing its losses, as well as on the secondary use of waste heat. The direct result of using RES devices is also a reduction in greenhouse gas …

Blockchain applications in management: A bibliometric analysis and literature review

2021

Blockchain has gained substantial recognition for its ability to induce transformation and innovation in existing business models and frameworks. Consequently, the application of this technology to the management domain and its processes has attracted increasing interest from academia and industry. Although research addressing the use of blockchain in management has gained momentum, this field presents a discontinuous overview of the current scope and boundary of the knowledge thereon. This study addresses this lacuna using bibliometric analyses to synthesize the prior literature. Data from Scopus 586 articles, entailing contributions from 72 countries, 273 journals, 1016 organizations, and…

En contexte ou hors contexte : lecture des matériaux et lecture du bâti

2020

Le choix des matériaux occupe une place importante dans l’élaboration du projet architectural, et détermine des orientations essentielles pour le chantier, dans la réalisation de celui-ci, son organisation, voire sa progression. Loin de se résumer à un simple descripteur ou accessoire de la stratigraphie du bâtiment, les matériaux de construction sont avant tout le reflet d’une réalité complexe du chantier à la fois matérielle et immatérielle : projet, exigences et capacité financière du commanditaire, réseaux d’échange, environnement sollicité. Leur prise en compte dans l’analyse du bâti transcende la logique stratigraphique, en épaulant celle-ci là où elle fait défaut et en replaçant la r…

Longitudinal Study of Cytokine Expression, Lipid Profile and Neuronal Growth Factors in Human Breast Milk from Term and Preterm Deliveries

2015

Breast milk (BM) is considered as a reference for infant nutrition. The role of bioactive components, such as cytokines, hormones, growth factors (GFs) and fatty acids (FAs) is poorly known, but they might be implicated in immune response development. The aim of this study was to identify the lipid profile and the spectrum of cytokines and neuronal GF in BM samples and analyse the influence of gestational age and lactation time on these components. This study used a longitudinal prospective method for the characterization of cytokines, FAs and GFs global profiles in 120 BM samples from 40 healthy mothers (20 preterm and 20 term) collected as colostrum, transitional and mature milk. The cyto…

Current economic downturn and supply chain: The significance of demand and inventory smoothing

2014

The aim of this article is to analyse and quantify the effects of demand and inventory smoothing into supply-chain performance, facing the extreme volatility and impetuous alteration of the market produced by the current economic recession. To do so, we model a traditional serial three-stage supply chain and we test five settings of order smoothing under two shocks in the market demand, and we measure effects in terms of internal process benefits and customer service level of all supply chain partners. Results show that the implementation of this inventory strategy should be based on reward schemes; in fact a higher level of smoothing can generally improve the performance of the upstream st…

Contribution de l’artère auriculaire postérieure à la vascularisation du nerf facial dans l’espace préstylien : étude anatomique et conséquences chir…

2008

INTRODUCTION: The aim of our study was to establish a systematization of collateral branches originating from posterior auricular artery to facial nerve in prestylian space. MATERIALS AND METHODS: Thirty posterior auricular arteries were studied on 15 fresh cadavers after selective patent blue injection. We observed subsequent colouration of facial nerve. Number and topography of collateral branches were highlighted. RESULTS: Posterior auricular artery supplied facial nerve in 67%. Collateral branches dedicated to facial nerve could be classified into three types: type 1 corresponded to one artery in prestylian space, type 2 to several branches in prestylian space; finally type 3 featured s…
