The use of cork in the thermoregulation of beehives

Experimental insulated beehive with cork panel and interior wall detail

The aim of this trial was to : a) increase thermoregulation efficiency of beehives by using cork in the construction of hive walls, thus improving bee health and hive productivity; b) contribute to the maintenance of traditional apiculture practices of Mediterranean agro-silvo pastoral systems, as historical findings indicate a widespread use of cork for the construction of rustic hives;  c) favour a better use of a secondary product of the cork processing industry (granulated cork); d) produce lighter and more resistant hives, compared to wooden hives; e) promote the use of cork as a...

STRADIVERNIS: study of an organic source varnish based on colophane of maritime pine and linen oil

Violin, in reference to the famous violin maker Antonio Stradivario

The aim of the project is to develop an industrially producible bio-sourced varnish based on gum rosin and linseed oil, inspired by the ancient know-how of the violin maker Antonio Stradivari (1644-1737). The difficulty is to meet the specifications of an industrial manufacture while achieving high performance of the varnish.

Wild medicinal, aromatic and honey plant species of the southeastern part of the Samoborsko gorje

http://pinova.hr/hr_HR/aktualno/agrotehnika-i-uzgoj-stolisnika

Plešivičko gorje (Plesivica hills) is located in the far eastern part of Žumberak-Samoborsko gorje Nature Park, near the towns of Samobor and Jastrebarsko. The highest parts of this hill area are wooded, and beneath this area there are meadows which are close to arable land - fields, orchards and vineyards. The aim of this study was to determine the flora of meadows in Plešivica hills and to isolate and describe medicinal, aromatic and honey plants.

Traditional collection and use of medicinal plants in the Knin area

Artemisia absinthium L.

In the past, herbs were the only cure for the disease, and learning about herbs was based only on human experience. They found the medicine in their environment, where they learned to recognize the plants and to determine how to use it. Knowledge and experience have been passed down from generation to generation, so today there are many who, thanks to the knowledge and experience of their loved ones, have become successful users and growers of medicinal plants, although unfortunately some of the knowledge about medicinal plants has probably fallen into oblivion, given that no one ever...

GO PinusResina

Monthly new wounds

The PinusResina initiative aims to identify/establish new value chains for the competitive and safe transformation and recovery of pine resin in high value-added products, with the mission of increasing the competitiveness and sustainability of Pinus pinaster and Pinus pinea forest in Portugal, in particular by enhancing resin constituents for new fine chemistry markets - resin chemical industry as the main economic factor in pine ecosystems; toxicity assessment of derived products; analyze the variability of resin composition, biotransformation and the exploitable...

Assessing the proportion of cork that a stopper should have from a mechanical perspective

Fig. 1. Different wine stoppers.

The objective of this study is to determine the proportion of cork that micro-agglomerated and synthetic cork stoppers should contain to assure that their mechanical properties are similar to those of a natural cork stopper. The properties that characterize the mechanical behaviour of the stoppers in the corking and uncorking operations are: compression, relaxation and extraction.

Energy value of Eucalyptus cultivated in Tunisia

Coal minning at Cap Bon

In rural areas of Tunisia, the average wood consumption per household and per year is between 1.8 and 5.9 tones. The highest consumption was noted in the forest regions of Sejnane, Boussalem and Jendouba. Results show that traditional bread baking represents 60 to 70% of the percentage of wood consumed in households. With a view to satisfying the increasingly growing needs for firewood and charcoal in rural areas, we have initiated a selection research program oriented towards more intensive wood production including wood that can be used for energy purposes. In this work, we propose to...

The Value Chain of Aleppo Pine Seeds and the Value Added of Vegetable Oil Extracted from Seeds

Aleppo pine seeds & Vegetable oil extracted from Aleppo pine seeds

Aleppo pine seeds (commonly called Zgougou) derive all their originality and nobility from the fact that they are consumed by Tunisians as part of their cooking habits. Zgougou is considered one of the most interesting NWFP due to socio-economic role and commercial value.  Aleppo pine seed oil can be extracted as for nutrition, or for medicinal and cosmetic uses.

The present work studies the conditions of exploitation of seeds in the forest, the yield of vegetable oil extracted, its physicochemical qualities and the possibilities of valorizing the press cake obtained after...

Essential oils of Eucalyptus: Comparative performance and promotion of their use

1. Leaves and flowers of Eucalyptus lehmannii – Arboretum of Korbous / 2.Leaves and flowers of Eucalyptus gillii – Arboretum of HajebLayoun / 3. Leaves and flowers of Eucalyptus leucoxylon – Arboretum of Korbous

The current exploitation of rosemary and myrtle (native species with relatively high yield of EO) occupies an important place in the forestry sector and a significant socio-economic interest. Eucalyptus trees can play a predominant and substantial role thanks to their richness in essential oils, their composition and their commercial value.

This objective necessarily involves the identification of eucalyptus EO species and the selection of the most efficient in terms of the yield of essential oils and the presence of the most dominant active compounds which are preferentially sought...

Characterization of Melia azedarach. L (leaves and fruits) and their insecticidal effects (Aphis punicea)

Melia azedarach L. ( tree, leaves & fruits)

Melia azedarach, also called Lilas of indes, classified under the family of Meliaceae. It is an ornamental tree native to India, presented in several countries of tropical and subtropical regions, especially in Tunisia. The objective of this study is the valorization of plant extracts in the manufacture of organic products to minimize the import of chemicals to human health and the environment.
