Authors: Tollner Ernest W. , Douglas-Mankin Kyle R. 
Published: December 2017

Abstract. This article introduces the five papers in the “International Watershed Technology” collection. These papers were selected from 60 technical presentations at the fifth biennial ASABE 21st Century Watershed Technology Conference and Workshop: Improving the Quality of Water Resources at Local, Basin, and Regional Scales, held in Quito, Ecuador, on 3-9 December 2016. The conference focused on solving spatial and temporal water quality and quantity problems and addressed topics such as watershed management in developing countries, aquatic ecology and ecohydrology, ecosystem services, climate change mitigation strategies, flood forecasting, remote sensing, and water resource policy and management. While diverse, the presentation topics reflected the continuing evolution of the “data mining” and “big data” themes of past conferences related to geospatial data applications, with increasing emphasis on practical solutions. The papers selected for this collection represent applications of spatial data analyses toward practical ends with a theme of “tools and techniques for sustainability.” The papers address a range of topics, including the matching of crops with water availability, and assessing the environmental impacts of agricultural production. The papers identify some of the latest tools and techniques for improving sustainability in watershed resource management that are relevant to both developing and developed countries. Keywords: Data mining, Modeling, Research, Sustainability, Water quality, Water supply.

Published: December 2017

Abstract. This article introduces the fourteen articles that comprise the “Crop Modeling and Decision Support for Optimizing Use of Limited Water” collection. This collection was developed from a special session on crop modeling applications in agricultural water management held at the 2016 ASABE Annual International Meeting (AIM) in Orlando, Florida. In addition, other authors who were not able to attend the 2016 ASABE AIM were also invited to submit papers. The articles summarized in this introductory article demonstrate a wide array of applications in which crop models can be used to optimize agricultural water management. The following section titles indicate the topics covered in this collection: (1) evapotranspiration modeling (one article), (2) model development and parameterization (two articles), (3) application of crop models for irrigation scheduling (five articles), (4) coordinated water and nutrient management (one article), (5) soil water management (two articles), (6) risk assessment of water-limited irrigation management (one article), and (7) regional assessments of climate impact (two articles). Changing weather and climate, increasing population, and groundwater depletion will continue to stimulate innovations in agricultural water management, and crop models will play an important role in helping to optimize water use in agriculture. Keywords: Agricultural water management, Crop modeling, Evapotranspiration, Irrigation, Irrigation scheduling.

In medicine, the fruits of Vaccinium vitis ideaea L. and Oxycoccus palustrie Pers. are widely used. Vaccinium fruits possess antioxidant, expectorant, diuretic, antitumour and hypercathartic action. Oxycoccus fruits have antioxidant, diuretic, antifebrile and antioxidant effect. These qualities depend on a complex of biologically active substances such as vitamins, hormones, macro- and micronutrients. Macro- and micronutrients contained in fruits are able to prevent the nutrient deficit which can cause some hard diseases. At the same time knowledge of toxic elements gives us information about pollution degree of studied fruits. Therefore, the aim of our study was qualitative detection and quantitative determination of element composition of fruits of Vaccinium vitis ideaea L. and Oxycoccus palustrie Pers, picked in Western Siberia (Tomsk oblast, Tomsk region). Determination of elemental composition was performed by methods of neutron activation analysis, atomic emission spectroscopy and mass spectrometry. Studied samples contain important nutrients which are found in vitamins and nutritional supplements, widely used in officinal and traditional medicine and in industry.

The content and composition of phenolic compounds in leaves of 3 Nitraria L. species from 12 populations have been studied with a high-performance liquid chromatography (HPLC). The investigation has detected 17 phenolic compounds, the maximum number of components is 12 indicated in leaves of N. pamirica L. Vassil. and N. schoberi L. plants in 2 populations, the minimum – 6 components – has been revealed in leaves of N. komarovii Iljin et Lava. Hyperoside (O-glycoside of quercetin), narcissin (O-glycoside of isoramnetin), quercetin (flavonol) and luteolin (flavon) have been identified. Studied plants accumulate a significant amount of phenolic compounds. Their content reaches 2,57% in leaves of N. schoberi L., 3,96% in N. komarovii. It was marked seasonal dynamics of a number of substances, in particular, lower narcissin content during plants fruiting compared to a flowering stage. The study results allow making an assumption of species peculiarities of phenolic compounds composition and content in N. schoberi and N. komarovii. The components composition is poorer in extracts of N. komarovii leaves, however, they shows higher content of total phenolic compounds compared with N. schoberi plants. At the same time N. pamirica sample is close to N. schoberi one based on a multivariate analysis of phenolic compounds composition and content.

Thermal gravimetry analysis (TGA) and differential scanning calorimetry (DSC), scanning electron microscopy (SEM), FT-IR spectroscopy, and thermal adsorption of nitrogen (BET) methods were used to study the thermal destruction of woody biomass of aspen (bark and wood) in argon and air in the temperature range from 25 to 800 °C. The composition and properties of the products obtained as a result of thermal decomposition of the initial wood biopolymers are characterized. It is established that the main range of thermal decomposition of wood in an inert medium included an interval from 227 to 500 °C, and aspen bark covered a temperature range from 180 to 600 °C. In the air atmosphere, the temperature zone of thermal decomposition narrows, the loss of mass of matter is observed in two temperature intervals of preferential decomposition of the substance with a shift toward a decrease in the maximum rate of decomposition for the bark (~40 °C), and for wood – 34,6 °C.

Plant remains from the Middle–Late Jurassic Daohugou site of the Yanliao Biota in Inner Mongolia, China
Authors: Pott Christian , Jiang Baoyu 
Published: December 2017

AbstractA late Middle–early Late Jurassic fossil plant assemblage recently excavated from two Callovian–Oxfordian sites in the vicinity of the Daohugou fossil locality in eastern Inner Mongolia, China, was analysed in detail. The Daohugou fossil assemblage is part of the Callovian–Kimmeridgian Yanliao Biota of north-eastern China. Most major plant groups thriving at that time could be recognized. These include ferns, caytonialeans, bennettites, ginkgophytes, czekanowskialeans and conifers. All fossils were identified and compared with species from adjacent coeval floras. Considering additional material from three collections housed at major palaeontological institutions in Beijing, Nanjing and Pingyi, and a recent account in a comprehensive book on the Daohugou Biota, the diversity of the assemblage is completed by algae, mosses, lycophytes, sphenophytes and putative cycads. The assemblage is dominated by tall-growing gymnosperms such as ginkgophytes, czekanowskialeans and bennettites, while seed ferns, ferns and other water- or moisture-bound groups such as algae, mosses, sphenophytes and lycophytes are represented by only very few fragmentary remains. The floral composition underlines the Callovian–Kimmeridgian age of the Yanliao Biota. The Daohugou/Yanliao flora is a typical member of the Middle to Late JurassicConiopteris-Phoenicopsisassemblage of north-eastern China, differing from the Early Cretaceous Jehol flora. Both floras probably belong to the same cycle of volcanism and sedimentation, although the Daohugou Bed is older than the Yixian Formation. The Yanliao fossil assemblage is placed in a larger palaeo-phytogeographical context and its relationships with Middle–Late Jurassic floras from north-eastern China, north-eastern and eastern Siberia and Japan are evaluated.

Pollen morphology of extant Winteraceae: a study allowing SEM-based affiliation of its fossil representatives
Authors: Grímsson Friđgeir , Xafis Alexandros , Neumann Frank H. , Zetter Reinhard 
Published: December 2017

AbstractWhen applying high-resolution microscopy, the pollen morphology of extant taxa can be used to classify fossil pollen, that is, to address the latter in the established systematic-phylogenetic framework. Here we investigate tetrads and pollen features of 20 different Winteraceae species, most of them belonging to the early-diverging generic lineagesTasmannia,DrimysandPseudowintera. The tetrads and pollen are grouped into eleven pollen types based on diagnostic features observed by both light and scanning electron microscopy. The high-resolution scanning electron micrographs of recent material allow detailed comparison with fossil material, resulting in a more accurate affiliation of fossil tetrads/pollen to extant lineages. As a case study, early Miocene Winteraceae tetrads from South Africa are re-examined and formally described. The systematic placement of the African fossils is discussed in light of the pollen types presented here.
Characterization and ecological significance of a seed bank from the Upper Pennsylvanian Wise Formation, southwest Virginia
Authors: Yehnjong Petra S. , Zavada Michael S. , Liu Chris 
Published: December 2017

AbstractSoil seed banks are important to the maintenance and restoration of floras. Extant seed banks exhibit unique characteristics with regard to the distribution of seed size and seed density. Seeds were recovered from the Upper Pennsylvanian Wise Formation in southwest Virginia. Structurally preserved seeds were also examined from coal balls of the Pennsylvanian Pottsville and Allegheny Groups, Ohio. The size distribution of the seeds from the Wise Formation is similar to that of structurally preserved seeds of the Upper Pennsylvanian Pottsville and Allegheny Group coal balls. In contrast, the seed size distributions in extant wetland, grassland, woodland and forest habitats are significantly narrower than that of seeds from the Pennsylvanian seed banks. Larger seeds are less dependent on light for germination, and aid in seedling establishment more than smaller seeds, especially in dense stable forests where disturbance events are rare. Large seed size may contribute to increased seed longevity, which reduces the effect of environmental variability on seed germination and development. The significantly larger size of the Palaeozoic seeds may have imparted an advantage for seedling establishment in the dense Palaeozoic forests. The preponderance of large seeds may be a result of the absence of large seed predators (e.g. herbivorous tetrapods), and may have been an evolutionary strategy to minimize damage to the embryo from a predator population dominated by small invertebrates with chewing or sucking mouthparts. The estimated seed density of 192 seeds/m2in the Palaeozoic seed bank falls within the range of modern seed banks, but at the lower end of modern seed bank densities in a variety of habitats.

Published: December 2017

AbstractIn order to assess the environmental indicator potential of wasp nests and termite mounds, the palynomorph content of three randomly selectedMacrotermessp. mounds (termitaria) and twoVespula vulgarisnests collected on the University of Lagos campus were examined. Palynological analysis showed the presence of 298 well-preserved palynomorphs showing characteristic morphological features. The recovered palynomorphs included pollen, pteridophyte spores and fungal spores, along with insect parts (106), diatoms (7) and a protist (1). The pollen assemblage of termite mounds comprised 78 pollen and pteridophyte spores, with Poaceae and Arecaceae pollen as dominants. In the wasp nest the pollen assemblage comprised 28 pollen and spore taxa, with Poaceae and Arecaceae pollen also dominant. Both mounds and nests had, besides diatoms, six pollen and spore taxa: Poaceae, Amaranthaceae, Pteridophyte spores, Arecaceae,Raffiasp. andRhizophorasp. Vegetational grouping of the recovered pollen and spores indicated five phytoecological groups: secondary forest, mangrove swamp forest, freshwater, open vegetation and Poaceae. In statistical analyses, termite mounds had a higher species richness value (2.08 as compared to 1.99 from the wasp nests), while the wasp nests had a higher species diversity value (0.997 as compared to 0.845 from the termite mounds). Pollen analyses of the termite mounds and wasp nests suggest that both could be useful tools in environmental studies. This is the first attempt to evaluate the potential of termite mounds and wasps nest as natural pollen accumulators in Nigeria. The results suggest new possibilities for the use of the pollen records preserved in termite mounds and wasp nests for environmental studies.
Position-force control of mobile manipulator – nonadaptive and adaptive case
Authors: Kaczmarek Mirela , Domski Wojciech , Mazur Alicja 
Published: December 2017

AbstractThis article presents a control algorithm for nonholonomic mobile manipulators with a simple, geometric holonomic constraint imposed on the robot’s arm. A mathematical model in generalized, auxiliary and linearized coordinates is presented, as well as the constrained dynamics of the robotic system. A position-force control law is proposed, both for the fully known robot’s model, as well as for the model with parametric uncertainty in the dynamics. Theoretical considerations are supported by the results of computer simulations.
Offset-free nonlinear Model Predictive Control with state-space process models
Authors: Tatjewski Piotr 
Published: December 2017

AbstractOffset-free model predictive control (MPC) algorithms for nonlinear state-space process models, with modeling errors and under asymptotically constant external disturbances, is the subject of the paper. The main result of the paper is the presentation of a novel technique based on constant state disturbance prediction. It was introduced originally by the author for linear state-space models and is generalized to the nonlinear case in the paper. First the case with measured state is considered, in this case the technique allows to avoid disturbance estimation at all. For the cases with process outputs measured only and thus the necessity of state estimation, the technique allows the process state estimation only - as opposed to conventional approach of extended process-and-disturbance state estimation. This leads to simpler design with state observer/filter of lower order and, moreover, without the need of a decision of disturbance placement in the model (under certain restrictions), as in the conventional approach. A theoretical analysis of the proposed algorithm is provided, under applicability conditions which are weaker than in the conventional approach. The presented theory is illustrated by simulation results of nonlinear processes, showing competitiveness of the proposed algorithms.

Published: December 2017

Abstract
The article presents the influence of natural and anthropogenic factors on the chemical and physical properties of surface water and groundwater in the area of the city of Inowrocław. It has been shown that the properties of the waters were most strongly affected by the specific geological structure (the city is located within the Zechstein salt dome) as well as the long-term influence of a salt mine and soda plant. The composition of most analysed samples was dominated by Ca2+, Na+ and Cl− ions. In places of heavy industrial activity, some water parameters were several time higher than permissible limit values according to Polish standards. It is concluded that, due to the threat to the city’s drinking groundwater resources and fertile soils, the surface water and groundwater in the area in question require permanent monitoring.
