Sensus divinitatis. Exercises in Philosophical Theology
2012
Solveigas Krūmiņas-Koņkovas monogrāfijā aplūkotas diskusijas, kas šobrīd risinās filozofiskajā teoloģijā, piemēram, par ticības konceptu un ticības racionalitāti, reliģisko pieredzi, zinātnes un reliģijas attiecībām, ļaunuma problēmu un citiem tematiem. Grāmata rakstīta belles-lettres žanrā, tas ir, no vienas puses, grāmatā ir gan racionāla argumentācija, gan citāti, atsauces, personu un atslēgvārdu rādītāji un cits akadēmiskais instrumentārijs, no otras puses, tā ir dienasgrāmata ar piezīmēm par izlasīto, kur vienā lappusē analītiskās filozofijas kārtulas var nomainīt dzejas rindas un šī nomaiņa ir absolūti intuitīva: spriedumi, kurus var reizēm neizteikt, ieslēpjot asociācijās un dodot la…

The Italian Almond Industry: New Perspectives and Ancient Tradition
2014
The almond industry in Italy presents a high degree of structural variability that is determined by the jeopardized coexistence of old, traditional orchards and new plantations that differ each other not only in terms of age but also mainly in terms of orchard system. Apulia and Sicily still remain the most important production areas where the 90% of the almond orchards are concentrated. In this southern part of Italy, almond and its derivatives still remain really important. In the last two decades, the Italian almond industry did not show a regular trend, neither with respect to production nor to acreage. An innovative almond industry revealed its consistency year after year since 2000: s…
Effect of rootstock vigor and in-row spacing on stem and root growth, conformation, and dry-matter distribution of young apple trees
2003
The effects of M.9 and MM.106 rootstocks and in-row spacing (0.4, 0.7, and 1 m) on the vegetative behavior of three-year-old apple (Malus domestica Borkh) trees were studied. Analysis of digital images was used to estimate canopy and root growth and conformation (shape and size), whereas dry matter distribution was used to determine partitioning to various plant parts. Trees on less vigorous M.9 rootstocks showed reduced stem and root growth as they produced less and/or shorter shoots and less and/or shorter and thinner roots. Canopy spread area (CSA) and volume were similar for trees on both rootstocks and differences in stem length density (stem length per unit canopy volume; SLD) compens…
Transplantation assessment of degraded Posidonia oceanica habitats: site selection and long-term monitoring
2014
A model developed for Zostera marina was adapted and used to select suitable areas for Posidonia oceanica transplantation in the Gulf of Palermo, where recent rehabilitation programmes have reduced human pressure. This model consists of three steps: (1) habitat selection, by calculation of the Preliminary Transplant Suitability Index (PTSI); (2) field assessments and test-transplanting, to evaluate the site suitability and to estimate the effects of tearing on transplant units (about 50%); (3) identification of suitable restoration sites, by calculation of the Transplant Suitability Index (TSI). A new parameter was added to the literature model: the number of grids detached, which is linked…

Responses of Young Peach Trees to Root Confinement
1994
Rooted cuttings of Nemaguard peach [Prunus persica (L.) Batsch.] were grown in 0.18-, 0.36-, 0.90-, and 2.40-liter containers for 16 weeks to study the influence of root confinement on growth, gas exchange, water uptake, and leaf carbohydrate and nutrient content. An automatic nutrient-solution dispensing system was used to ensure uniform fertility among treatments and to prevent drought stress. Leaf area and stem length were reduced by root confinement 6 to 7 weeks after transplanting, and differences among treatments increased throughout the experiment. Final tree dry weights were reduced by 51% over a 13-fold reduction in rooting volume, but dry weight partitioning was largely unaffected…
Early bearing and vegetative growth of 153 Sicilian olive accessions
2018
In 2014, an olive germplasm collection was established in south-western Sicily, Italy. The collection included 153 Sicilian accessions and 3 international varieties (reference), each with 7 trees, spaced at 5×2 m and trained to hedgerow system. The aim of the trial was to study early growth and yield responses of the accessions to super-high planting density (SHD). Trunk cross sectional area, tree height, pruning weights, shoot positioning, blooming and fruit yield (kg tree-1) were measured in 2015 and 2016. Based on trunk growth and amount of prunings, the 153 accessions were separated into four categories of vigor as it follows: very high vigor (6 accessions), high vigor (13), medium vigo…
The impact of the age of vines on soil hydraulic conductivity in vineyards in eastern Spain
2017
Soil infiltration processes manage runoff generation, which in turn affects soil erosion. There is limited information on infiltration rates. In this study, the impact of vine age on soil bulk density (BD) and hydraulic conductivity (Ks) was assessed on a loam soil tilled by chisel plough. Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from planting: 0 (Age 0; just planted), 1, 3, 6, 13, and 25 years (Age 1, Age 3, Age 6, Age 13, and Age 25, respectively). The One Ponding Depth (OPD) approach was applied to ring infiltration data to estimate soil Ks with an α* parameter equal to 0.012 mm-1. Soil bulk density for Age 0 was about 1.5 times greate…
