Siderophore and Its Applications in the Field of Bioenvironmental Researches

Iron, one of the essential micronutrients, is needed for electron transport and metabolic processes in almost all living organisms. The ferric form (Fe3+) of iron is insoluble in nature and inaccessible at physiological pH (7.35–7.40). Under iron-limited conditions, metal-chelating agents such as siderophores are synthesized by many bacteria and a few fungi. Siderophores have a high affinity fo...

Geological Field Mapping

A map showing the distribution of rock units and structures across a region representation, usually on a plane surface is termed a geological map. A map showing the occurrence of structural features across a region, the distribution of rock units, and their type and age relationship is termed a geological map. Geological field mapping is the process of selecting an area of interest and identify...

Participation of people living in rural areas of Eskisehir province in field researches, and factors affecting their rates of participation

OBJECTIVE The aim of the study was to determine participation rates of people living in the rural area of Eskisehir in field researches, and the factors influencing this. METHODS This descriptive study was performed with 1,482 people aged 18 and above in two districts of Eskisehir. Data were collected with a 16 question questionnaire using the face-to-face interview technique. Data were analy...

Uplift, denudation, and their causes and constraints over geological timescales

We define uplift and denudation, then review the basic principles underlying the mechanisms for producing uplift, and the methodologies used to quantify the geological timescale denudation history of uplifted regions. Uplift is represents work done against gravity, and does not necessarily lead immediately to rapid denudation. The causes of uplift can be categorised according to the principal d...
