Savings of Small Farms: Their Magnitude, Determinants and Role in Sustainable Development. Example of Poland

Savings are a catalyst for capital creation and are the driving force behind economic growth and development. The degree of development achieved by farms will largely depend on their ability to accumulate income and their way of spending. The aim of the article is to determine the savings-generating potential of small farms in Poland and the impact of savings on their sustainable development. In this article, firstly, the literature on savings in small farms and their role in sustainable development is synthesized. Secondly, presents empirical research that was conducted considering the economic and social characteristics of 1485 small farms to help understand saving behaviors in the chosen context. The research material consisted of data on entities participating in the Polish Farm Accountancy Data Network (FADN) in 2017. The factors influencing the generation of savings were identified using the logit regression model. The results of the research indicate great diversity in the scale of savings generated by small farms in Poland. Moreover, the study showed that 4 out of 21 variables characterizing small farms were significant, with a good fit of the model as evidenced by the model quality assessment measures used (coefficient R2count and ROC curve). It was found that two variables, namely area of farmland and gross value added, each had a statistically significant positive influence on the probability of generating higher savings by small farms in Poland. On the other hand, the possession of liabilities and gross investment each had a statistically significant negative influence on the accumulation of higher savings. The research reveals some limitations that may hinder the mobilization of savings by small farms and thus affect their sustainable development. Therefore, as recommendations, we present measures that can increase savings by small farms in Poland.
A Novel LNP-Based Chlamydia Subunit Vaccine Formulation That Induces Th1 Responses without Upregulating IL-17 Provides Equivalent Protection in Mice as Formulations That Induced IL-17 and Th1 Cytokines

Sexually transmitted Chlamydia infections can lead to the development of debilitating diseases such as chronic pelvic pain, ectopic pregnancy, pelvic inflammatory disease, and infertility. It has been proposed that immunity against Chlamydia infection and disease may be determined by a balance of IL-17 signaling. We sought to evaluate novel formulations for a candidate Chlamydia vaccine, consisting of Chlamydia major outer membrane protein (MOMP) alone or in combination with polymorphic membrane protein D (PmpD) and polymorphic membrane protein G (PmpG) as target immunogens. Native MOMP (nMOMP) isolated from C. muridarum elementary bodies (EBs) and recombinant PmpD and PmpG proteins were adjuvanted with Monophosphoryl lipid A (MPLA), in one of two formulations containing either lipid nanoparticles (LNPs) or the cationic lipid dimethyldioctadecylammonium bromide (DDA). Antibody titers to C. muridarum, nMOMP, and EBs were evaluated by ELISA, and T-cell responses by intracellular cytokine staining (ICS). Protection from challenge was determined by qPCR and gross pathology. All mice immunized with the new vaccine formulations showed significantly higher antibody titers to nMOMP (P<0.001) and C. muridarum EBs (P<0.001), when compared to the negative control group (adjuvant alone). Antibody titers in vaccine groups with Monophosphoryl lipid A (MPLA)+LNP were higher as compared to the MPLA+DDA group (P<0.001) except for groups 6 (Cm nMOMP+PmpG+PmpD p73+PmpD p82+MPLA+DDA) vs 7 (Cm nMOMP+PmpG+PmpD p73+PmpD p82+MPLA+LNP) for both C. muridarum EBs and PmpG; the groups were not statistically significant. ICS analysis showed more robust CD4+ T-cell responses (IFN-γ/IL-2/TNF-α) in the dimethyldioctadecylammonium bromide (DDA) and LNP groups compared to the adjuvant alone group. The combination of DDA and MPLA gave robust Th17 responses in comparison to MPLA and LNP group. Immunized groups also showed protection from challenge with C. muridarum , as evidenced by a reduction in bacterial shedding from the vagina for all groups (P<0.003) compared to shedding from the adjuvant control, Group 1. Both vaccine formulations generated robust immunological responses and both vaccine formulations were protective by reducing bacterial shedding after challenge. This data indicates equal protection can be achieved without the induction of Th17 responses.
Equation of state and high-pressure phase behaviour of SrCO3

Abstract. The high-pressure phase transition of strontianite (SrCO3) was investigated at ambient temperature by means of powder and single-crystal X-ray diffraction. The samples were compressed in a diamond anvil cell to a maximum pressure of 49 GPa. Structure refinements confirm the existence of SrCO3 in the low pressure aragonite-type phase Pmcn (62) up to about 26 GPa. Above this pressure, SrCO3 transforms into a high-pressure phase with post-aragonite crystal structure Pmmn (59). Fitting the volume extracted from the compression data to the third-order Birch–Murnaghan equation of state for the low-pressure phase of SrCO3 yields K0=62.7(6) GPa and K0′=3.2(1), and for the high-pressure phase this yields K0=103(10) GPa and K0′=2.3(6). The unit cell parameters change non-uniformly, with the c axis being 4 times more compressible than the a and b axes. Our results unequivocally show the existence of a Pmmn structure in SrCO3 above 26 GPa and provide important structural parameters for this phase.
Organizational Dehumanization and Emotional Labor: A Cross-Cultural Comparison Between Vietnam and the United Kingdom

This study examined cross-cultural differences in the relationships between organizational dehumanization and both job satisfaction and turnover intentions through emotional labor (i.e., surface acting). In particular, we expected that power distance, that is, a critical value usually discussed as part of the national culture, would mitigate the deleterious effects of both organizational dehumanization and surface acting on job satisfaction and turnover intentions. Data were collected from employees in two countries that differ in power distance, namely Vietnam (N = 235) and the United Kingdom (N = 334). First, we found that perceptions to be dehumanized by one’s organization were indirectly related to poor job satisfaction and more turnover intentions through surface acting, regardless of the country. Second, our results showed that the deleterious effects of both organizational dehumanization and surface acting on work-related outcomes were weaker in Vietnam (a high power distance country) than in the United Kingdom (a low power distance country). Theoretical and practical implications are discussed from the perspective of organizational dehumanization and emotional labor literature.

Hydrogen atom transfer reactions of N+2 with H2, HD, and D2 from thermal to 10 eV center of mass

Reactions of N+2 ions with H2, HD, and D2 are studied under single‐collision conditions in a guided‐ion beam mass spectrometer over a much broader range of interaction energies than in any previous study, including the low energy region of thermal to 0.1 eV. Reactant ions are formed in a flow tube source to ensure thermalization. Possible reaction mechanism are discussed, and the present results are compared to previous measurements. We find that the reaction proceeds at the rate predicted by the classical ion–molecule capture collision theory at thermal energy, but exceeds this prediction at energies above 0.1 eV. This behavior is discussed and attributed to details of the interaction between the N+2+H2 surface and the N2+H+2 surface along which the hydrogen atom transfer reaction proceeds. Intramolecular isotope effects and product ion dissociation behavior suggest that the reaction occurs via a direct mechanism with no long‐lived intermediate at elevated energies.
Some properties of η-convex stochastic processes

The stochastic processes is a significant branch of probability theory, treating probabilistic models that develop in time. It is a part of mathematics, beginning with the axioms of probability and containing a rich and captivating arrangement of results following from those axioms. In probability, a convex function applied to the expected value of an random variable is always bounded above by the expected value of the convex function of the random variable. The definition of η-convex stochastic process is introduced in this paper. Moreover some basic properties of η-convex stochastic process are derived. We also derived Jensen, Hermite-Hadamard and Ostrowski type inequalities for η-convex stochastic process.
Internationalisation of developing economy small and medium-sized enterprises: social capital and learning in Palestinian pharmaceutical firms

Purpose –The paper examines the role of learning through social capital on the internationalisation process of small and medium-sized enterprises (SMEs) based within extreme contexts. The study focuses on the Palestinian pharmaceutical industry. Design/methodology/approach – The inductive, exploratory research used in this study adopts a case study approach. Data derived from semi-structured in-depth interviews held with senior management and companies’ founders were analysed using content and thematic analysis techniques. Findings – The findings suggest that accumulated learning by SMEs seeking international expansion is enhanced with stronger social capital ties and networks through structural, relational and cognitive mechanisms. Serendipity and liability effects enabled modes of foreign entry with higher degrees of commitment than efficacy-related factors. Practical implications – The Palestinian pharmaceutical industry presents a benchmark for other industries in comparable developing economy contexts. This study elucidates the important interrelationship between social capital and learning for SMEs seeking to expand internationally; the findings have implications for regional policymaking in developing economy regions. Originality/value – The case study investigation focuses on the pharmaceutical industry and SMEs operating within the extreme context of Palestine, thereby contributing insights in an area of management enquiry that is under-represented in the extant literature.
Regenerative Belt Conveyor versus Haul Truck-Based Transport: Polish Open-Pit Mines Facing Sustainable Development Challenges

The mining industry is facing sustainable development challenges, among which the energy efficiency issues seem to be of major importance. As transport of the mined ore is considered as one of the most energy intensive operations, the improvement of its energy efficiency is a key indicator in terms of sustainable actions taken by mining companies. In open-pit mines, the material handling operations are mostly performed with trucks. Their electrified version—truck trolley systems—surpass diesel trucks’ efficiency while comparing the increased production capacity and the reduction of maintenance cost and fuel consumption. The paper analyzes the opportunities and benefits of the replacement of an ore transport system based on hauling trucks with a regenerative belt conveying in an open-pit mine. Presented case study has been analyzed from energy consumption and environmental impact reduction perspectives. Generally, conception of a regenerative conveyor is based on recuperation of energy or continuous braking needed while a conveyor is running downhill. Energy generated during the braking process (converted from the potential gravitational energy of the conveyed material) is fed back to the electrical grid. Then the regenerative conveyor can be considered as a machine that mines energy as an additional by-product of an exploited deposit. It was shown that difference in transportation cost between haul trucks and energy efficient regenerative conveyors is around 95%. The paper points the conditioning elements to allow the implementation of a regenerative belt conveyor system.
STUDY OF THE EFFECT OF TWO BPO/AMINE INITIATION SYSTEMS ON THE FREE-RADICAL POLYMERIZATION OF MMA USED IN DENTAL RESINS AND BONE CEMENTS

ABSTRACT The kinetics of the free radical bulk polymerization of methyl methacrylate (MMA) was studied by DSC, using the benzoyl peroxide (BPO)/amine initiation system. N,N dimethyl-4-aminophenethyl alcohol (DMPOH), which is a newly synthesized and used amine in the preparation of acrylic dental resins and bone cements was examined, and the results compared to the most commonly used in these applications amine, the N,N dimethyl-p-toluidine (DMT). For both amines, the effect of the molar ratio of BPO/amine and of the reaction temperature, on the polymerization kinetics was investigated. The prepared polymers were characterized by determination of the average molecular weights (M¯ n and M¯ w ) and molecular weights distribution (M¯ w /M¯ n ) using Gel Permeation Chromatography. DMPOH was found to lead in slightly higher polymerization rates, lower gel times and lower molecular weights than DMT. The values of these parameters for both amines were influenced by the molar ratio of BPO to amine, when the product of the concentrations of these was kept constant. The highest polymerization rate occurred in the lowest gel time, resulting in polymers with the lowest molecular weight, and was observed when a molar ratio of about 1.5 BPO/amine was used. However, the final monomer conversion was found to be independent of the molar ratio and amine used. The activation energy of polymerization was found to be 51.8 kJ/mol K for BPO/DMPOH and 47.1 kJ/mol K for BPO/DMT.
Preparation, Characterization and Processing of PCL/PHO Blends by 3D Bioplotting

Abstract Blends of polycaprolactone (PCL) and poly(3-hydroxyoctanoate) P(3HO) were prepared by melt compounding. These immiscible blends exhibited droplet-matrix morphology at compositions up to 30 wt% P(3HO). Even though the addition of amorphous P(3HO) decreased the crystallinity of PCL, the crystallization temperature of the blends increased by 6 to 7 8C. Blends containing up to 30 wt% P(3HO) had higher crystallization rates, and lower crystallization half-times compared to neat PCL. The viscosity of PCL decreased upon addition of P(3HO), making the blends suitable for processing using a 3D bioplotter. Compositions with 10 to 30 wt% P(3HO) were ideal for processing, because of their improved crystallization kinetics, reduced stickiness and good flow properties. Estimation of the interfacial tension by fitting the Palierne model to the linear viscoelastic properties of the blends revealed good compatibility, which gave rise to synergistic effects in the thermal and mechanical properties. The fibres prepared by 3D bioplotting maintained droplet matrix morphology, with finer particle size than the original compounded material. In addition to favourable viscosity and thermal properties, the extruded fibres containing 30 wt% P(3HO) had comparable modulus to the neat PCL, while exhibiting good ductility. These blends may be suitable alternatives to PCL for biomedical applications, because they provide a range of crystallinities, crystallization rates and viscosities.
Bringing the problem home: The anti-slavery and anti-trafficking rhetoric of UK non-government organisations

Rhetoric is a way to explain policy problem framing by recognising the practical necessity to persuade audiences in contextual situations. Modern slavery and human trafficking is a complex and emotive problem, simplified through rhetorical demands to motivate an audience of supporters. This article analyses rhetoric by 212 UK anti-trafficking and anti-slavery non-government organisations (NGOs) to uncover rhetorical practices and their effects on policy framing, supplemented by archival research to compare past and present anti-slavery oratory. Our data show NGOs use rhetoric to motivate supporters and promote a humanitarian problem frame, in opposition to a state-driven security frame. Findings confirm other research in identifying an emphasis on female victims and on sexual over labour exploitation. Past and present rhetoric are equivalent in terms of liberal, Christian values (ethos) and appeals to pathos through sympathy for victims. Historical rhetoric is distinctive in arguing for the equal human status of slaves, whereas contemporary activists argue victims are denied agency. Contemporary rhetoric represses the question of migration, whereas past rhetoric is more deliberative. Rhetoric varies with the requirements of persuasion related to contextual distance, between unlike humans in the past, but in regard to geographical distance today.
NEW APPROACH TO THE ANALYSIS OF HOP OIL

Gas-liquid partition chromatography has allowed the separation of eighteen components of hop oil obtained from ripe, undried Fuggles hops; the presence of a number of additional highly volatile compounds is not excluded. Detailed characterization of the individual components has not yet been accomplished, but the indications are that the principal compounds present include myrcene, methyinonylketone, β- or γ-caryophyllene, and humulene, these together comprising more than 70% of the total oil of this hop sample. There appears to be no evidence for the presence of geraniol.
Enzyme immobilization onto renewable polymeric matrixes: Past, present, and future trends

In this review, we present an overview of the different renewable polymers that are currently being used as matrixes for enzyme immobilization and their properties and of new developments in biocatalysts preparation and applications. Polymers obtained from renewable resources have attracted much attention in recent years because they are environmentally friendly and available in large quantities from natural sources. Different methods for the immobilization of enzymes with these matrixes are reviewed, in particular: (1) binding to a prefabricated biopolymer, (2) entrapment, and (3) crosslinking of enzyme molecules. Emphasis is given to relatively recent developments, such as the use of novel supports, novel entrapment methods and protocols of polymer derivatization, and the crosslinking of enzymes. © 2015 Wiley Periodicals, Inc.

Water management and wheat yields in ancient China: Carbon isotope discrimination of archaeological wheat grains

The evaluation of ancient crop production and its response to climate change is key to exploring the ancient demographic and social changes. Wheat is currently the third most widely cultivated crop worldwide and was a major component across of the agricultural systems of the ancient Eurasia. In this study, the Δ13C values of 116 charred wheat grains from 28 archaeological sites, with direct AMS 14C dating of 3952 ± 66 to 389 ± 73 cal yr BP, across northern China are reported. The result shows that the Δ13C values estimated wheat yields ranged from 0.5 to 2.5 Mg ha−1, during the past 4000 years. The water supply and grain yield of wheat cultivation is the highest in China during the Bronze Age; however, the water supply and yield were significantly affected by climate fluctuation in the middle-late Holocene. No significant long-term trend of increasing wheat yield is observed over this interval, but a correlation between Δ13C values estimated wheat yield and cyclical climate changes can be noted.
Thiamine pyrophosphate riboswitch regulation: a new possible mechanism involved in the action of nalidixic acid

Abstract Objectives The development of novel antibiotic compounds requires riboswitches; in fact, riboswitches are RNA elements present in the 5′ untranslated region of bacterial mRNA and have a metabolite-binding aptamer domain and an expression platform regulating the expression of vital genes. In the present research, one riboswitch, namely thi-box riboswitch with distinct regulatory mechanisms, was studied. It recognizes Thiamine Pyrophosphates (TPP) regulating TPP-biosynthesis genes in Escherichiacoli. Methods First, the compounds similar to riboswitch ligands were studied, and their binding with the riboswitch and nucleosides was investigated by molecular docking. Then, compounds containing high binding energy were chosen, and their minimum inhibitory concentration in E. coli was determined by the MIC test. Finally, the binding of compounds to nucleotides and RNA was investigated by measuring the absorbance spectrum through NanoDrop and circular dichroism (CD). Results In the thi-box riboswitch, nalidixic acid was found to have the best binding energy (−5.31 kJ/mol), and it inhibited E. coli growth at the minimum inhibitory concentration of 125 μg/mL, and it could bind to ribonucleosides and RNA in vitro. Conclusions One possible mechanism involved in the action of nalidixic acid in inhibiting the E. coli growth is to influence thi-box riboswitch.
Design and applications of light responsive liquid crystal polymer thin films

Responding to external stimuli is a trait observed in all living organisms. Modern artificial materials have adopted this profound characteristic, thereby commencing the field of stimuli–responsive systems. Liquid crystal polymers are attractive members of this family of systems owing to the available control on their anisotropic properties capable of generating complex morphologies under external stimuli. Liquid crystal polymer systems have been designed to respond to various stimuli such as heat, light, pH, humidity, and electric and magnetic fields. The attainable shapes and topographies open exciting possibilities for novel applications in a wide range of different fields such as microfluidics, artificial muscles, haptics, and optical functions. The microstructural design of liquid crystal polymers leading to diverse applications is the focus of this review. We conclude by presenting the future prospects and developments in these promising material systems.
