Orientacja procesowa w zarządzaniu publicznym łańcuchem dostaw

2015

W artykule podjęto problematykę możliwości wdrożenia orientacji procesowej do zarządzania publicznym łańcuchem dostaw. Wskazano na znaczenie uwarunkowań polityczno-prawnych, wyznaczających system celów i tworzących ramy realizacji zadań publicznych. Pokazano, że istotne znaczenie ma identyfikacja procesów podstawowych i wspomagających oraz koordynacja styków w łańcuchu tworzenia wartości publicznej. Podkreślono wagę wyznaczania jednostek odpowiedzialnych za realizację procesu, zwłaszcza w kontekście mnogości podmiotów, w tym prywatnych, realizujących świadczenia publiczne.

2017

International audience; Two three-dimensional cadmium metal organic frameworks with general formula [Cd-2(L-1)(H2O)(3)](NO3)(0.7)(HCOO)(0.2)Br-0.1 (Cd2L1, L-1 = 1,4,7-tris(4-carboxybenzy1)-1,4,7-triazacyclononane) and Cd(HL2)(H2O)(2) (CdL2, L-2 = 1,4,7-tris(3-(4-benzoate)prop-2-yn-1-yl)-1,4,7-triazacydononane) based on 1,4,7-triazacyclononane N-functionalized by different arylcarboxylic acids were prepared under solvothermal conditions and characterized by single crystal X-ray analysis and porosity measurements. The crystal structure of Cd2L1 reveals a cationic net with a bcs topology,. and nodes are constituted by dinuclear cadmium complexes, in which each cadmium atom adopts a hexacoordin…

Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).

2020

Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…

Właściwości strukturalne i aromatyczność ftalocyjaniny cynku

2017

Metaloftalocyjaniny są grupą związków, które otworzyły nowy rozdział w wielu dziedzinach przemysłu i nauki. Dzięki czterem pierścieniom izoindolowym połączonym ze sobą za pomocą mostków azometinowych, powstaje szesnastoatomowy układ sprzężonych wiązań podwójnych składających się na makrocykl, który zawiera 18 zdelokalizowanych elektronów π spełniając regułę aromatyczności Hückla (4 n + 2, n = 4).Pojęcie aromatyczności jest jednym z najpopularniejszych terminów używanych w analizie związków π-elektronowych. Jej definicja jest niejednoznaczna. Cechami układów aromatycznych są podwyższona trwałość, zmiana długości wiązań oraz szczególne właściwości magnetyczne. Możliwe jest jednak odkształceni…

Long-term changes in pigmentation of arctic Daphnia provide potential for reconstructing aquatic UV exposure

2016

Abstract Despite the biologically damaging impacts of solar ultraviolet radiation (UV) in nature, little is known about its natural variability, forcing mechanisms, and long-term effects on ecosystems and organisms. Arctic zooplankton, for example the aquatic keystone genus Daphnia (Crustacea, Cladocera) responds to biologically damaging UV by utilizing photoprotective strategies, including pigmentation. We examined the preservation and content of UV-screening pigments in fossil Daphnia remains (ephippia) in two arctic lake sediment cores from Cornwallis Island (Lake R1), Canada, and Spitsbergen (Lake Fugledammen), Svalbard. The aims were to document changes in the degree of UV-protective p…

Modeling multipartite virus evolution: the genome formula facilitates rapid adaptation to heterogeneous environments

2020

Multipartite viruses have two or more genome segments, and package different segments into different particle types. Although multipartition is thought to have a cost for virus transmission, its benefits are not clear. Recent experimental work has shown that the equilibrium frequency of viral genome segments, the setpoint genome formula (SGF), can be unbalanced and host-species dependent. These observations have reinvigorated the hypothesis that changes in genome-segment frequencies can lead to changes in virus-gene expression that might be adaptive. Here we explore this hypothesis by developing models of bipartite virus infection, leading to a threefold contribution. First, we show that th…

Adaptation of French society to aging : aging today in an Age-Friendly City : integration, discrimination and roles of public policy

2019

This PhD work aims to analyse the way French cities seize and implement the Agefriendly Cities approach on their territories. Thanks to seventy semi-guided interviews, a second data analysis and active observation, we studied how thirteen French cities decided to implement the Age-friendly Cities approach.This work of research revolves around ideas about how to combat ageism, about the importance of consulting the inhabitants and of using a cross-disciplinary way of work. Like that, it aims to analyse how French cities adapted their local public policies in coherence with the frame given by the Age-friendly Cities approach, the national policies and the recommendations of the international …
