Phenology of the Mencía Variety Cultivated in a Territory Included in the UNESCO World Network of Biosphere Reserves


The study of grapevine phenology is very useful for vineyard management and control, as it allows the application of phytosanitary treatments at the phenological stages where the crop is most susceptible to different diseases, mainly cryptogamic. This work describes the phenological behaviour of the red Mencía variety, the most common in the Ribeira Sacra Designation of Origin (Northwest Spain), as well as its thermal requirements throughout its vegetative cycle. It has been carried out in a vineyard located in the highest areas of the Sil River canyon, during the year 2021. The observations were made on 10 vines and the phenological scale used was the one standardized by the BBCH. The vegetative cycle, from the beginning of sprouting to the harvest, took 163 days, during which 5097 GDD (Growing Degrees-Days) were accumulated.

In agronomic, economic, social, historical, and cultural terms, the grapevine is one of the most important crops in the northwest of the Iberian Peninsula, including areas such as Galicia, León, and the north of Portugal. According to the Spanish Wine Market Observatory (OEMV), the vineyards in this area cover an area of some 25,823 hectares. This study focuses on the Ribeira Sacra Designation of Origin, a territory that offers an excellent opportunity to study what has been called “Heroic Viticulture”, in reference to the special orographic characteristics of the area, which determine the cultivation methods http://www.cervim.org/.

 Lateral Rock Characteristic Evidence of Hydrocarbon Restoration from Post-Stack Impedance Inversion: A Case Study of ZED-field Offshore Niger Delta Lateral predictions of rock properties that are descriptive of a reservoir have been studied using a model-established seismic inversion approach that was used to convert input seismic data into an acoustic impedance structure to optimize hydrocarbon restoration in the field. This was actualized by integrating wireline logs and 3D post stack seismic data procured from ZED-Field offshore Niger Delta. The inversion system employed in this study comprises of forward modelling of reflection coefficients starting with a low-frequency impedance model induced from well logs and convolution of the reflection coefficients with the source wavelet extracted from the seismic input. P-impedance analysis at reservoir C5000 delineated from the control well gave a near perfect correlation of 0.998109 (≈ 99.8 %) between the original P-impedance log, in...

 Sustainable Development: Reality Or Myth? Since the United Nations Environment Conference in Stockholm (1972), the concept of sustainable development has steadily made its way among individual scientists and international organizations. The apotheosis of this development was the adoption by the United Nations in 2015 of the 17 Sustainable Development Goals. However, many scientists and politicians were skeptical about the concept of sustainable development, since the results of implementing sustainable development in different countries were far from expected. Many decisions taken at the level of the UN and other international organizations turned out to be unfulfilled. In my opinion, as well as some other Russian scientists, the concept of sustainable development is an unrealistic project, it is a myth, although it is very positive and humane. Sustainable development goals can be achieved only by the most economically developed countries entering the era of post-industrialism. In...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...
