Municipal Climate Change Adaptation GOVERNANCE in Latvia: ApproachING Cross-sectorial and Multi–instrumental understanding

2021

Climate change adaptation being one of today’s main challenges on global agenda do affect people worldwide, but even though most decisions regarding climate change governance are made at the international or national level, the implementation of these decisions in most cases takes place at the local level. Municipal climate change adaptation research project in Latvia was carried out with special emphases on main stakeholder understanding, preparedness and communication factors using several complementary research methods – case study research in Salacgriva coastal municipality, sociological surveys with both Salacgriva town households / inhabitants (home visits / questionnaires) and also n…

Strategie di web-marketing: concreta opportunità per le aziende florovivaistiche delle regioni del Mezzogiorno d'Italia

Improving scalability of web applications based on stability of the network with the use of controller PI

2015

This paper presents mathematical model of a computer network and then the model has been presented in the form of a flow chart. RED algorithm is a standard in computer network. RED algorithm has been replaced with the PI controller. In the article it has been assumed that a computer network is a particular dynamic system and it can be examined using known methods of the theory of dynamic systems. We tested of stability for the real computer networks. This method is called method the uncertain parameters space.

The competitive development of flowers and ornamentals firms through the use of web-marketing strategies: a survey in the convergence objective regio…

2011

The growth of ICT, and in particular the integrated use of internet within firm marketing strategies, has brought about deep changes at both sector and firm level. Firm processes have been drastically modified in their communication and promotional aspects. In particular, firmcustomer relationships are changing and therefore internet represents a preferential means, not only for transferring the firm image in the global communication, but above all in order to build a dialogue and a continuous interaction which contribute to consumers’ fidelization. This empirical research proposal is to be considered in the framework of “Business to Consumer” relationships and is addressed to the flowers a…

Trophic transfer of polychlorinated biphenyls (PCB) in a boreal lake ecosystem: Testing of bioaccumulation models

2013

Understanding the fate of persistent organic chemicals in the environment is fundamental information for the successful protection of ecosystems and humans. A common dilemma in risk assessment is that monitoring data reveals contaminant concentrations in wildlife, while the source concentrations, route of uptake and acceptable source concentrations remain unsolved. To overcome this problem, different models have been developed in order to obtain more precise risk estimates for the food webs. However, there is still an urgent need for studies combining modelled and measured data in order to verify the functionality of the models. Studies utilising field-collected data covering entire food we…

Whole-lake experiments reveal the fate of terrestrial particulate organic carbon in benthic food webs of shallow lakes

2014

Lake ecosystems are strongly linked to their terrestrial surroundings by material and energy fluxes across ecosystem boundaries. However, the contribution of terrestrial particulate organic carbon (tPOC) from annual leaf fall to lake food webs has not yet been adequately traced and quantified. In this study, we conducted whole-lake experiments to trace artificially added tPOC through the food webs of two shallow lakes of similar eutrophic status, but featuring alternative stable regimes (macrophyte rich vs. phytoplankton dominated). Lakes were divided with a curtain, and maize (Zea mays) leaves were added, as an isotopically distinct tPOC source, into one half of each lake. To estimate the …

A multivariate analysis of phytoplankton and food web changes in a shallow biomanipulated lake

1996

1. Phytoplankton dynamics, food chain changes and resilience in Lake Zwemlust, a shallow lake in The Netherlands, are described for the period 1986-94. 2. After biomanipulation in 1987, the lake moved through two alternative states, while the external nutrient loadings were maintained. A clear-water phase, mostly dominated by macrophytes, persisted from 1987 to 1991, and a rather turbid state, dominated by algae, occurred in the summers of 1992-94, after several consecutive and sustained perturbations affecting different parts of the food web in the lake. These two periods were characterized by different community structures. 3. The phytoplankton assemblage gradually changed in a pattern th…

No evidence of trophic cascades in an experimental microbial-based soil food web

1998

Trophic-dynamic theories predict the biomass and productivity of trophic levels to be partially top-down regulated in food webs, and that the top-down regulation will manifest itself as cascading trophic interactions. We tested the two principal predictions deduced from these theories: trophic cascades of (1) biomass regulation and (2) productivity regulation occur in food webs. We created three food webs with either one, two, or three trophic levels in soil microcosms containing a sterilized mixture of leaf litter and humus. Twenty species of bacteria and fungi formed the first trophic level, a bacterivorous nematode (Caenorhabditis elegans) and a fungivorous nematode (Aphelenchoides sp.) …

The scientific and practical fields-especially high-performance sports-increasingly request a stronger focus be placed on individual athletes in human movement science research. Machine learning methods have shown efficacy in this context by identifying the unique movement patterns of individuals and distinguishing their intra-individual changes over time. The objective of this investigation is to analyze biomechanically described movement patterns during the fatigue-related accumulation process within a single training session of a high number of repeated executions of a ballistic sports movement-specifically, the frontal foot kick (mae-geri) in karate-in expert athletes. The two leading r…

Spot mounding and granulated wood ash increase inorganic N availability and alter key components of the soil food web in clear-cut Norway spruce fore…

2012

Abstract The interactive effects of site preparation (spot mounding) and fertilization (granulated wood ash) on soil properties, soil micro- and mesofauna and ground vegetation were studied in two Norway spruce plantations established in clear-cut forests in Central Finland. Half of the seedlings were planted on mounds created by the planting machine, and the rest on intact forest floor. Half of the seedlings on mounded and intact forest floor were fertilized by adding granulated wood ash to circular plots surrounding the seedlings. Initial samples were taken from mounded and intact soil immediately after planting in June. Samples were taken from all treated plots in the autumn in the first…
