This paper examines the effects of using natural and synthetic rooting hormones for cuttings propagation. The study used Saxegothaea conspicua Lindl, a Near Threatened conifer native to Chile and Argentina. A trial was set on 80 semi-ripe cuttings of S. conspicua applying both synthetic (IBA) and natural hormones derived from willow and lentils. This study evaluates and measures the rooting success of using different types of hormones at the end of the trial (such as development of roots, length, etc). It also aims to examine the level and type of auxins found in the lentil and willow rooting solution, if present. After evaluation of results of the present trial and the wider literature, this paper discusses the potential use of this type of natural hormones in future. This article is an extract from the author’s HND Specialist Project written for the RBGE Diploma in Horticulture with Plantsmanship in June 2018.

Spent Biomass

A spent biomass, which results from the biopharma industry, is stabilized and functionalized by biosorption with microelements. The efficiency of this new biomaterial was tested in two experiments: 1) In a mixture with soil to determine its effects of the germination capacity of cereals and vegetables, and 2) in a formulation of mixed fertilizers to determine its influence on the development and production of the two types of vegetables. The results obtained during germination experiments performed in pots showed that at a biomass concentration less than 20%, the germination output was greater than 95% and the germination index was almost 1. The experiments performed in land on vegetables (including Solanum lycopersicum and Capsicum annuum) featured six types of fertilizers formulated with new biomaterials. The obtained results indicated that two types of fertilizers (N 10:0:0 and NP 5:5:0), which were formulated with functionalized biomass and featured the microelements Co, Cu, Fe, Mn, and Zn, exhibited significant effects when compared with vegetables cultivated on unfertilized soil surfaces (the untreated variant). The studies regarding the effect of the new fertilizers obtained based on spent biomass from biopharma industry indicate the following: a) This material, even if it is stabilized and functionalized, cannot be used as such as a germination substrate for vegetables; in addition, it cannot be introduced into soil together with cereals seeds (during the autumn work), because the germination can be affected negatively; b) the functionalized biomass can be used in the formulation of different types of fertilizers; if these fertilizers are introduced into soil with the autumn plowing, then they may have a positive influence on the yield of some species of vegetable, such as Solanum lycopersicum and Capsicum annum. The new fertilizers have a major environmental impact due to: 1) Removal of waste, which results from pharmaceutical biosyntheses, with significant impact on soil pollution, due to its storage in the form of waste dumps, on the soil; 2) recovery and reinsertion into the natural circuit of nutrients like C, N, P, K, Mg, and Ca contained in spent biomass, by their reuse in agriculture; and 3) high content of compounds with C from spent biomass can improve in time the content of fulvic and humic acids in soil, with a positive effect on soil characteristics from an agronomic point of view.

As an acidic, ocean colloid polysaccharide, alginate is both a biopolymer and a polyelectrolyte that is considered to be biocompatible, nontoxic, nonimmunogenic, and biodegradable. A significant number of studies have confirmed the potential use of alginate-based platforms as effective vehicles for drug delivery for cancer-targeted treatment. In this review, the focus is on the formation of alginate-based cancer-targeted delivery systems. Specifically, some general chemical and physical properties of alginate and different types of alginate-based delivery systems are discussed, and various kinds of alginate-based carriers are introduced. Finally, recent innovative strategies to functionalize alginate-based vehicles for cancer targeting are described to highlight research towards the optimization of alginate.

Abstract Organo- and hydrogels have been proposed in the restoration field to treat different types of surfaces. The possibility to retain solvents and to have a controlled and superficial action allowed to use these materials for the removal of very thin layers applied on ancient historical objects, when the under paint layers are particularly delicate and water sensitive. In the last years, an increased attention has been devoted to the proposal of more healthy products to guarantee the safeguard of the operators. Few attention has been devoted to the development of green methods which foresee the use of renewable and biodegradable materials. The aim of this paper is to test a green organo-gel for the cleaning of water sensitive surfaces like varnished egg tempera paintings. The gel has been tested experimented on mock ups varnished with natural and synthetic materials and has been validated on a small portion of a Cimabue painting for the removal of two varnishes applied on two different test areas of the painting.

SUMMARYWe developed an individual-based (IB) model to explore the stochastic attributes of state transitions, the heterogeneity of the individual interactions, and the impact of different network structure choices on the poliovirus transmission process in the context of understanding the dynamics of outbreaks. We used a previously published differential equation-based model to develop the IB model and inputs. To explore the impact of different types of networks, we implemented a total of 26 variations of six different network structures in the IB model. We found that the choice of network structure plays a critical role in the model estimates of cases and the dynamics of outbreaks. This study provides insights about the potential use of an IB model to support policy analyses related to managing the risks of polioviruses and shows the importance of assumptions about network structure.

SUMMARYThis paper proposes a new dynamic planning navigation strategy for use with mobile terrestrial robots. The strategy was applied to situations in which the environment and obstacles were unknown. After each displacement event, the robot replanned its route using a control algorithm that minimized the distance to the target and maximized the distance between the obstacles. Using a spatial localization sensor and a set of distance sensors, the proposed navigation strategy was able to dynamically plan optimum routes that were free of collisions. Simulations performed using different types of environment demonstrated that the technique offers a high degree of flexibility and robustness, and validated its potential use in real applications involving mobile terrestrial robots.

The need for automated identification of a disease makes the issue of medical biometrics very current in our society. Not all biometric tools available provide real-time feedback. We introduce gas discharge visualization (GDV) technique as one of the biometric tools that have the potential to identify deviations from the normal functional state at early stages and in real time. GDV is a nonintrusive technique to capture the physiological and psychoemotional status of a person and the functional status of different organs and organ systems through the electrophotonic emissions of fingertips placed on the surface of an impulse analyzer. This paper first introduces biometrics and its different types and then specifically focuses on medical biometrics and the potential applications of GDV in medical biometrics. We also present our previous experience with GDV in the research regarding autism and the potential use of GDV in combination with computer science for the potential development of biological pattern/biomarker for different kinds of health abnormalities including cancer and mental diseases.

Sustainable economic growth and increase in the level of population wellbeing, the diminution of energy dependence of Ukraine from the neighboring countries can only be achieved through the use of different types of biofuels, the practice of which is confirmed by the experience of other countries. One of the most promising types of fuel is agricultural plants, or rather the waste that remains after harvesting. The purpose of this study is to assess the energy potential of agricultural plants in Ukraine on the example of the Lviv region with an idea that it might reduce the energy dependence of Ukraine on Russia and other countries and will become a basis for improving the national energy management system. Assessment of the energy potential of agricultural plants was carried out on the example of the Lviv region. This assessment is based on all three components of the energy potential of agricultural plants (both theoretically and technically feasible and economically justified).According to the results of calculations, waste of wheat, other grain crops and rape has the largest energy potential. In particular, the energy potential of agricultural biomass of the Lviv region makes theoretically possible (maximum) 2.1 million tons of fuel equivalent, technically achievable 0.915 million tons of fuel equivalent (including losses), and economically expedient (optimal) 0.74 million tons of fuel equivalent. The evidence revealed in the study confirmed the fact that Ukraine has sufficient energy potential use of agricultural crops. All these measures correspond to the state strategy for the development of the energy potential of Ukraine. Considerable attention is paid to the need to form an optimal management system for the use of energy potential of agricultural plants in Ukraine. Given the significant economic efficiency of agricultural wastes, the expediency of its use as biofuels has been substantiated. The most effective in energy terms are grain crops (wheat, barley), which should be preferred in the process of biomass creation.

Gastrointestinal tumors, including pancreatic and colorectal cancers, represent one of the greatest public health issues worldwide, leading to a million global deaths. Recent research demonstrated that the human heavy chain ferritin (HFt) can encapsulate different types of drugs in its cavity and can bind to its receptor, CD71, in several solid and hematological tumors, thus highlighting the potential use of ferritin for tumor-targeting therapies. Here, we describe the development and characterization of a novel nanomedicine based on the HFt that is named The-0504. In particular, this novel system is a nano-assembly comprising an engineered version of HFt that entraps about 80 molecules of a potent, wide-spectrum, non-camptothecin topoisomerase I inhibitor (Genz-644282). The-0504 can be produced by a standardized pre-industrial process as a pure and homogeneously formulated product with favourable lyophilization properties. The preliminary anticancer activity was evaluated in cultured cancer cells and in a mouse model of pancreatic cancer. Overall results reported here make The-0504 a candidate for further preclinical development against CD-71 expressing deadly tumors.

Large Investment

A laboratory is a large investment of time and money for departments of chemistry yet discussions continue about its purpose in the educational process. Helping students navigate the three levels of representation; macroscopic, particulate and symbolic is a potential use of this time. This study looked at two different types of visualization for an electrochemistry laboratory in second semester general chemistry and the impact that the visualization type had on the student discourse. Macroscopic visualization (MV) was accomplished through a traditional hands-on laboratory and particulate visualization (PV) was achieved using a computer simulation featuring animated electrons and ions. The type of visualization impacted how much the students talked, who they talked to, and what they talked about. The MV students engaged in less peer-to-peer discussion than the PV students. The MV students expressed more excitement about their observations and were more focused on getting the data quickly. The MV spent most of their time physically doing the laboratory work while spending little time discussing the concepts. The PV students spent more time talking about concepts with their peers especially at the particulate level even answering macroscopic questions with particulate explanations. The type of visualization influenced all aspects of the student discourse.
