Food contact materials (FCMs) are materials that come in contact with food products such as food packaging which play a significant role in the food quality and safety. Plastic, which is a major food packaging material, harms the eco-system, wildlife, and the environment. As a result, numerous researches have been in progress on alternative polymers, which has similar properties as plastic but is also environmentally friendly (biodegradable). In recent years, the utilization of seaweed polysaccharides has piqued interest due to its biodegradability, non-toxicity, antioxidant capabilities, and excellent film formation ability. However, it has a number of drawbacks such as low …

An Evaluation Of The Hargreaves-Samani Method For Estimating Evapotranspiration Under Semi-Arid Conditions, Yusuf Aydin
The Philippine Agricultural Scientist
It is suggested by the Food and Agriculture Organization of the United Nations (FAO) to use the FAO56-Penman-Monteith (FAO56-PM) model as the standard model in reference crop water consumption studies. However, the climate parameters required by the standard model cannot be fully and reliably obtained in under developed or developing countries. Hence, the Hargreaves-Samani (HS) equation is used as an alternative to the FAO56-PM model since it can be used for calculations with less climate data. In this study, ETo-PM and ETo-HS values calculated at 8 provinces in Southeastern Turkey using the IAM-ETo software were evaluated and …
