Pašnovērtētās uzvedības problēmas, sociālais atbalsts no vienaudžiem un uztvertais skolas klimats 16-18 gadus veciem jauniešiem

2018

Maģistra darba pētījuma mērķis bija izpētīt kā pašnovērtētās uzvedības problēmas, uztvertais skolas klimats un sociālais atbalsts no vienaudžiem savā starpā mijiedarbojas 16-18 gadus veciem jauniešiem. Balstoties uz izanalizēto literatūru, tika izvirzīti trīs pētījuma jautājumi: 1) Kādas saistības pastāv starp pašnovērtētām uzvedības problēmām, uztverto skolas klimatu un tā dimensiju vienaudžu sociālo atbalstu 16-18 gadus veciem jauniešiem? 2) Kā uztvertais skolas klimats prognozē pašnovērtētas uzvedības problēmas 16-18 gadus veciem jauniešiem? 3) Kā uztvertā skolas klimata dažādas dimensijas prognozē pašnovērtētas uzvedības problēmas 16-18 gadus veciem jauniešiem? Pētījumā piedalījās vispā…

Suullisen testauksen hyödyntäminen vieraskielisessä opetuksessa

2013

Suullista vuorovaikutusta pidetään merkittävänä tekijänä kielenoppimisessa. Etenkin vieraskielisen opetuksen eli CLIL-opetuksen saralla oppilaiden puheen tuottaminen nähdään tärkeänä osana oppimista sekä tiedonrakentamista. Tämän tutkimuksen tehtävänä oli selvittää kuinka pareittain tehtävää suullista testausta voidaan hyödyntää CLIL-opetuksessa. Suullisen testin hyödyntämistä lähestytään kielen oppimisen, aihesisällön oppimisen, arvioinnin sekä oppilaiden mielipiteiden näkökulmista. Tutkimuksen painoarvoa nostaa se, että vieraalla kielellä opettamisen arviointi on todettu olevan haasteellista, eikä selkeitä suuntaviivoja sen suhteen ole. Tutkimus on tehty koulussa, jonka vieraskielistä ope…

Une vigne gallo-romaine de plaine à Gevrey-Chambertin (Côte-d'Or), Ier-IIe s. ap. J.-C.. Implications pour le développement des terroirs viticoles de…

2011

Recent excavations at Au-dessus de Bergis in Gevrey-Chambertin (Côte-d’Or, Burgundy) brought to light numerous, rectangular aligned pits interpreted as an ancient vineyard dated from the end of the 1st/mid-2nd century to the 3rd century AD. The vineyard is largely extent in area and was bounded to the south by a hedge or fence. It was composed of parallel rows that may have been trained over and along high, inclined wooden frames. Vine stocks were renewed by layering, over several generations of plants, according to some agricultural wine-growing techniques recommended by Latin agronomists. This vineyard attests to the establishment of vineyards from the mid-1st century AD in places differe…

Apoptosis in human unfertilized oocytes after intracytoplasmic sperm injection

2005

Objective To investigate the presence of programmed cell death in unfertilized oocytes after intracytoplasmic sperm injection (ICSI), assuming that previous apoptotic events could be correlated with the fertilization failure. Design Comparison of the rate of DNA fragmentation in human oocytes at different stages of maturation soon after pick-up (control) and in unfertilized oocytes after ICSI treatment. Setting In vitro fertilization (IVF) laboratory with extensive ICSI experience. Patient(s) Sixty-three patients undergoing assisted fertilization by ICSI. Intervention(s) Terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling (TUNEL) assay and anticaspase-3 cleaved…

Damping Provision by Different Virtual Synchronous Machine Schemes

2020

The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…

Sensitivity Analysis and Frequency Dynamics of Grid-Connected Converters with Virtual Inertia

2021

For the participation in the frequency control of the system, power converters can be controlled with different strategies and methods, sharing the common concept of virtual inertia capability. In this work, a sensitivity analysis of two main categories of converter controls with virtual inertia is presented. The considered schemes are a grid-following current vector control with additional virtual inertia block and a grid-forming control scheme based on virtual synchronous machine concept. A proper basis for the comparison is first assessed providing an analytical correlation between the control parameters of the two schemes. For the two control strategies, the sensitivity analysis of the …
