Published: October 2018

The reaction of new early ripening potatoes of Molly, Red Scarlett and Kolette varieties on the main processing of gray forest soil in the conditions of the forest steppe of the Middle Volga region was studied. The aim of the work is to determine the effectiveness of different soil treatment options. The work was performed on the experimental field of Kazan SAU in 2012-2015. The dumping of plowing at a depth of 20-22 cm was compared with a non-spinning loosening of 26-28 cm and processing of a BDP by 18-20 cm. It was established in the course of research that, without spilling, Molly’s variety, on an average for four years, yielded 36.29 tons per hectare, with the dumping of plowing 35.89 tons per hectare. In similar variants, Red Scarlett formed the yields of 38.66 and 37.96 tons per hectare, and the grade of Kolette - 34.29 and 35.84 tons per hectare. With all methods of soil treatment, more starch contained potato tubers of the Kolette variety. Depending on the variant of soil cultivation, it was 13.73-14.13% in tubers of this variety. Less starch (12.83-13.20%) contained tubers of the Molly variety. Vitamin C and protein was more contained in the tubers of the Red Scarlett variety.

Winter hardiness of plants depends on many factors: plant species, variety, duration of quenching phase and meteorological conditions. The reaction to stressful influences during the autumn-winter period is the changes in the cellular metabolism, in which the accumulation of various substances that protect plants from death occurs. Proline is a multifunctional amino acid, that accumulates in high concentrations in response to various abiotic stresses. The purpose of this study is to identify species and varietal differences in the accumulation of proline in winter crops in the Republic of Tatarstan. The material for research was the leaves of winter wheat plants (Triticum aestivum L.), winter rye (Secale cereale L.) and winter triticale (Triticosecale Witt.). The experiments were carried out under conditions of natural stress factors of three consecutive growing seasons of 2014-2017. To determine the state of wintering plants in dynamics, the content of free proline was determined by the Bates method. It is shown that the average values of proline content in winter rye and triticale increased from October to December, but decreased in February. Winter wheat had a further increase in the indicator. The amplitude of the oscillations in December in winter rye was 5.18-13.52 μmol/g, in winter triticale - 9.47-23.15 μmol/g, in winter wheat - 25.81-32.98 μmol/g. The greatest variability of proline values in the studied cultures was noted in February. For each of the winter crops, its reaction rate according to this criterion was revealed. However, there is an intraspecific specific character of the dynamics of the synthesis and breakdown of free proline. Among the studied varieties and hybrids of winter rye, 3 groups differed among themselves. The concentration of proline in the leaves of winter triticale approximated to the values of winter rye, and according to the dynamics of accumulation - to winter wheat.

Published: October 2018

In scientific work the estimation of technological parameters of grain of wheat varieties of different ecological groups is presented at cultivation in steppe of Orenburg region. Investigations of qualitative properties of grain of spring soft wheat revealed that high-grade grain forms varieties of steppe Volga, eastern and southern ecotypes. More vitreous grains are characteristic of varieties of steppe Volga and eastern ecological groups. Grain with a protein content of 14% and higher is characterized by varieties of forest-steppe West Siberian and forest-steppe eastern, steppe Volga, steppe eastern and steppe southern ecological groups. A high content of gluten (33-34%) was noted in varieties of the steppe Volga, eastern and southern ecotypes. From all studied ecotypes, a grain was obtained with quality gluten of Groups I-III. Most of the varieties of the forest-steppe West Siberian and eastern, steppe Volga, eastern and southern ecological groups in the steppe zone of the Orenburg region form 1-2 grade grains, and samples of forest North Russian and East Siberian forest ecological groups - 3-4 classes.

The research methodology is based on generally accepted silvicultural and taxation techniques, methods of observation, and the method of test plots. The objects of research were the forests of the Republic of Tatarstan. Forests were created on an area of 17 553 hectares with a clear cutting area of 9 190 hectares for the years 1962-2001 in the forest fund of the GKU “Sabinskoe Forestry”. A part of forest cultures was created under the canopy of soft-leaved stands, in which non-continuous logging was carried out, but they did not have a sufficient amount of conifer undergrowth. The number of self-seeding per 1 m2 of mineralized area with the disc soil mineralization of KLB-1.7 on average is 1.4 times more than in the control variant. The bulk of self-seeding settles in the middle of the prepared lanes and grounds. In 1990, the number of self-seeding at the center of the bands averaged 81%, and at the edges - 19%, with fluctuations in some areas from 51 to 85%. In the next 2 years, the number of self seeding at the center of the lanes decreased on average by 65%, at the edges to 97%. Consequently, in high-grade crops of spruce, one cannot count on the accumulation of self-seeding after sampling either every 4th or every 8th rows of crops and soil mineralization even with good seed yield. It is necessary to improve the method of cutting and soil preparation. The thinning of plantations in the adjacent rows at the same time as felling could be effective, but they were not considered in further studies, because clear felling showed its futility. Conducted long-term large-scale production experiments demonstrate the possibilities of transferring artificial forest ecosystems to the path of natural development by the system of complex logging.

Authors: Малов Николай , Malov Nikolay
Published: October 2018

The article deals with the growth and development of spring wheat plants, depending on the variety in the conditions of the Chuvash Republic. The rate and rhythm of development of field crops, the time of onset of phenological phases and the duration of the vegetation period generally determine the hereditary nature of plant varieties and the cumulative effect of all factors of plant life. A variety is a biological foundation on which all other elements of high productivity are built and one of the main factors of stable production of spring wheat grain. Strong and valuable varieties of spring wheat with a high potential yield, good responsiveness to mineral fertilizers and changes in agrotechnics during cultivation, resistant to unfavorable weather conditions during the vegetative period of plants, lodging, diseases, forming strong grain quality are used for cultivation. In this case, the variety is considered as the cheapest and available means of increasing the productivity of plants. In our studies for all the years of research, the onset of phenological phases of development depended on both varietal features, meteorological conditions during the vegetative period of plants and the biological characteristics of the varieties under study.

Technical progress and modernization of agricultural production lead to fluctuations in the level of demand and supply in the labor market and provoke a number of social and economic problems: rising unemployment, underemployment, chronic shortages or redundancy of certain professions, aging of staff, low wages, leading to high the turnover of personnel in agriculture, the reduction of labor competitiveness and the growth of social tension in society. In the conditions of increasing use of innovative technologies in agricultural production, qualified personnel become more and more popular every year, as well as receiving permanent additional education. However, the ongoing positive changes in mechanization and automation of production do not significantly affect the social and economic development of the rural population, which leads to staff turnover and aging of the workforce. In this regard, the purpose of the publication is to study the changes in the gender and quantity composition of workers in agricultural enterprises, assess the socio-economic conditions of rural development. The analysis of the state and trends of the personnel potential, the impact of the changes in technical and technological support on the deepening of its professional and qualification of the division of labor, which should ultimately be taken into account in the development of conceptual provisions for the forecasting of labor resources. Based on the results of the analysis, the causes of the identified problems were identified and measures for their solution were proposed.

The implementation of the cluster policy of the region is closely connected with the level of development of the scientific and innovation infrastructure and the activity of the subjects of innovation activity in the region. The article assesses the level of activity of the scientific and innovation sphere in the context of the life cycle phases of innovative enterprises in the region. In Omsk region, the key tool of financial support for innovations at the seed stage is the UMNIC program of the Foundation for Assistance to Small Innovative Enterprises in the scientific and technical sphere. Over the whole history of the contest, more than 16 000 projects of young scientists worth more than 5 billion rubles have been supported at the federal level, over 1 000 small innovative enterprises have been created, more than 2 000 jobs. In the Omsk region from 2007 to 2018, 260 program winners were given the opportunity to grant their research and innovation projects for the amount of 106.4 million rubles. The distribution of competitive applications in the directions and years is not uniform: the greatest number of applications fell on the direction “New devices and hardware complexes”, the smallest – “Modern materials and technologies for their creation”. At the stage of establishment of the enterprise, from 2014 to 20017. in the Omsk region, 72 applications were submitted for the START program of the Innovation Support Fund, of which 12 were supported by the Fund. The main problem in the Omsk region, as in Russia as a whole, at this stage is the lack of commercial competencies and presentation skills of scientists and inventors. The paper describes and defines key principles for the development of innovative infrastructure in the region, identifies the factors that impede the development of innovation in the region, gives recommendations on the activities of scientific and technical policies that stimulate the creation of innovative infrastructure elements in the region.

The work is devoted to the mathematical description of the process of occurrence and flow of mechanical soil erosion on slope fields and ways to reduce it. The dependences of mechanical erosion on the steepness of the slope, the type and parameters of the working unit, the direction of movement of the unit relative to the horizontal field are given. The obtained mathematical dependences allow us to calculate the displacement of the soil down the slope, depending on the type and parameters of the working unit and on the technology of tillage used. Purpose of the study. Reduction of mechanical soil erosion in slope fields by improving technologies and structural and technological parameters of tillage and seeding machines. Calculations showed that when the unit moves at an angle θ = 45 ÷ 70° to the horizontal of the field, the maximum displacement of the soil occurs by the lower wing of the working body (Δ1). Minimal mechanical soil erosion is provided for lancet working bodies when the unit moves relative to the horizontal of the field at an angle of 90 ± 35°, for unilateral working bodies - 120 ± 40°. It is desirable to avoid the direction of movement of the unit θ ≈ 0 ... 70°, when maximum mechanical erosion is observed when processing by one-sided working bodies (plow bodies) exceeding mechanical erosion when moving along the field horizontals 1.5 times.

During the tractors’ operation, they interact as a control object with dynamic loads during technological operations with climatic, operational, organizational conditions on the one hand, and technical operation on the other, i.e. machinery is influenced by operating conditions. A comprehensive, dimensionless indicator of the operating conditions of tractors in agricultural production is the level of their operation. The level of operation of the tractor is the state of their operation in the household, which is determined by the degree of implementation of technical maintenance activities of equipment and the percentage of attracting tractors in labor-intensive processes when used as intended. The theoretical level of operation of the tractor can vary from 0 to 1. At the same time, 1 corresponds to the operating state of the tractor, at which the resource consumption is minimal, i.e. the degree of implementation of generalized factors of technical operation meet the State Standard requirements and the tractor performs work with the lowest specific resistance; 0 - theoretical, corresponds to the operating state of the tractor, at which the resource consumption is maximum, i.e. technical operation of the tractor is not performed and the tractor performs works with maximum resistivity. We have determined the levels of operation of tractors and indicators of their reliability in the farms of the Republic of Tatarstan. As a result of joint mathematical processing, regularities of changes in these indicators were obtained depending on the level of operation of tractors.

Mechanisms of cardiovascular protection of non-insulin antidiabetic medications
Authors: Avogaro Angelo
Published: October 2018

Patients with type 2 diabetes mellitus die most frequently from cardiovascular disease (CVD). Metabolic control is a cornerstone of both primary and secondary prevention of CVD: its important is two-fold since the normalization of HbA1c not only counteracts the onset, and the progression of microvascular complication, but has also important and positive role in reducing the risk of major adverse cardiovascular events (MACE). However, among the available glucose-lowering medications, some exert a direct CV protection independently from their ability to normalize metabolic control. In this review I will highlight the pathophysiological mechanisms underlying the claimed cardiovascular protection of the different glucose-lowering drugs, the available evidence-based data for their protection, the potential adverse effects, and the different phenotypes of patients eligible for a specific treatment. The knowledge of pathophysiological mechanisms for CV protection of each glucose-lowering medication, and the constraints of their use supports the health care professionals to individualize the normalization of metabolic control in patients with type 2 diabetes mellitus.
Type 2 Diabetes Mellitus. From the start – combination therapy
Authors: Indovina Francesco , Falcetta Pierpaolo , Del Prato Stefano
Published: October 2018

Modern treatment of T2DM requires a shift in paradigm with appropriate intensification of therapy from the very first time of diabetes diagnosis. This is supported by data showing how even a moderate delay in achieving good glycemic control can translate into a later increased risk of developing diabetic complications. The recognition of the complexity of the pathogenesis of T2DM leads to the appreciation of the importance of attacking the disease from different angles, i.e. simultaneous tackling of multiple mechanisms contributing to hyperglycemia. From the turn of century a growing number of new anti-hyperglycemic agents have been made available. As compared to the older ones, these new medicines have a more targeted mechanism of action as they act at the level of the specific pathophysiologic disturbances accounting the development and progression of hyperglycemia. Because of that drugs can be use in combination taking advantage of their complementary mechanisms of action and synergistic. If introduced earlier in the natural history of the disease combination therapy may contribute avoiding undesirable exposure to even mild chronic hyperglycemia and provide early benefits. With respect to that in this review we will discuss advantages, disadvantages and still unanswered questions related to the use of early combination therapy in type 2 diabetes.

Primary hyperparathyroidism (PHPT) is caused by parathyroid malignant neoplasm in 1% of cases. The risk of the latter is higher in patients with symptomatic PHPT. The prognosis in this group of patients depends on the extent of the process and primary surgical intervention.
In these cases, the differential diagnosis between secondary foci in the bones associated with parathyroid cancer and hyperparathyroid osteodystrophy is a challenging problem.
This article describes two cases of severe PHPT accompanied by hyperparathyroid osteodystrophy suspected for metastatic parathyroid cancer. Positron emission tomography in combination with computed tomography (PET/CT) with 18F-fluorodeoxyglucose (18F-FDG) and/or 18F-fluorocholine was included in the examination algorithm. In both cases, pronounced bone changes similar to parathyroid metastases were observed. Accumulation of 18F-fluorocholine was also observed only in altered parathyroid gland. Histological examination of postoperative material verified benign parathyroid tumors, and characteristic lesions of bone tissue were regarded as areas of osteodystrophy.
Therefore, accumulation of 18F-fluorocholine at the areas of bone destruction does not enable differentiation between hyperparathyroid osteodystrophy and metastatic lesions; further research is required to assess sensitivity and specificity of the method with respect to topical diagnosis of altered parathyroid gland.
Correlation between type 2 diabetes mellitus and air pollution with suspended particles
Authors: Kolpakova Alla F. , Sharipov Ruslan N. , Volkova Oxana A.
Published: October 2018

The review presents the modern concept of the relationship between air pollution with fine particulate matter (PM) and the prevalence of diabetes mellitus (DM). The role of PM in the pathogenesis of DM, in particular, DM2, depending on their size, origin, chemical composition, and concentration in the air is discussed. For this purpose, we used materials from the articles indexed in the PubMed and RSCI databases. Road transport-related PM, containing intermediate valence metals are believed to be the most dangerous ones. Long-term exposure to high concentrations of fine and ultrafine PM is associated with the risk of type 2 diabetes and mortality. Short-term exposure to PM causes vascular insulin resistance and inflammation triggered by oxidative stress in the lungs. Oxidative stress caused by exposure to PM is the central stage of inflammatory reactions, leading to release of pro-inflammatory cytokines from cells and systemic inflammation. Exposure to PM sized 2.5 microns or less results in significant increase in expression of proinflammatory genes and activation of corresponding signaling pathways. Involvement of PM into impairment of glucose homeostasis and increase in inflammation in adipose tissue, liver, and central nervous system has been confirmed in models and experimental studies. The role of air pollution with PM in the pathogenesis of type 2 diabetes is still not fully understood, especially at the molecular and cellular level. The development of formalized descriptions of the processes mediating the effect of PM on the human body will provide better understanding of the role of air pollution with suspended particles in the pathogenesis of various diseases and, in particular, DM2, which can contribute to improvement of treatments and preventive measures.
Secondary acquired nasolacrimal duct obstruction after radioiodine therapy
Authors: Yartsev Vasily D. , Atkova Eugenia L.
Published: October 2018

Secondary acquired nasolacrimal duct obstruction after radioiodine therapy is a comparatively rare complication but it requires treatment at an early stage. The symptoms of secondary acquired nasolacrimal duct obstruction are tearing, eye redness, discharge at ocular surface, a mass growing at lacrimal sac site. The considered complication occurs after radioiodine therapy in dose of 150 mCi, the rate of occurrence is dose-dependent. There are no clinical guidelines for preventing this complication but there are reports of nasolacrimal duct preventive intubation and those about developing new drug agents that block an action of the protein that uptakes iodine in the nasolacrimal duct mucosa. For diagnosing, special diagnostic procedures and an ophthalmologist consultation are required. For the correction of this complication, conservative treatment (with low efficacy) and special surgical treatment are used, including nasolacrimal duct recanalization with different techniques and anastomosis between nasolacrimal duct and nasal cavity formation. In cases of early patient encounter, it is possible to use more functional and less invasive surgical techniques, in cases of late encounter, more invasive surgical techniques are used.

Published: October 2018

Congenital hyperinsulinism (CHI) is caused by insulin hyperproduction by β-pancreatic cells. CHI is associated with high risk of complications of chronic hypoglycemia, and therefore timely diagnosis of the disease and immediate initiation of therapy is a top-priority task. The choice of treatment tactics largely depends on the morphological form of the disease. Morphological form cannot be established based on clinical and laboratory presentation of the disease, ultrasound, MRI, computed and positron emission tomography (PET) with [18F]-fluorodeoxyglucose. Calcium stimulation test and percutaneous transhepatic blood sampling from the portal vein were previously used for differential diagnosis, but the results provided by these invasive studies are imprecise. At present, preoperative differential diagnosis of diffuse and focal forms of CHI is based on the data of genetic testing and radionuclide diagnosis ([18F]-DOPA PET). The article presents the first results of the use of [18F]-DOPA PET in CHI patients in the Russian Federation. Radionuclide study was performed in 17 patients with pharmacoresistant CHI followed by comparative analysis of the results of 18F-FDG PET/CT and histological picture of intraoperative pancreatic tissue samples, which is known as the gold standard for the differential diagnosis of HI histological forms.
Comparison of phosphor removal efficiency of rain treatment materials containing illite
Authors: Kim Yootaek , Chae Taesung
Published: October 2018

Artificial lakes constitute more than 40% of drinking water sources, and can be easily eutrophicated by accumulation of phosphor, nitrogen, and nutrition salts introduced by various industrial and domestic origins after 10–30 years of their construction. Specifically, the concentration of phosphor is considered as an important factor that influences eutrophication, and causes seven times the eutrophication of nitrogen. In the present study, porous ceramics were fabricated with bottom ashes (BA) from power plants for recycling purposes and illite, which is known to be an efficient absorption material for phosphor in water. The phosphor removal efficiency reached up to 59% when the composition rate of illite to BA was 4 to 6. The study indicates the possibility of developing phosphor absorbing porous ceramics by using spent materials such as BA as substitutes for expensive illite without a significant decrease in phosphor removal efficiency.
Tłumaczki chleb powszedni. Ludmiła Marjańska i Mary Swann
Authors: Rajewska Ewa
Published: October 2018

The article discusses a translation of a Carol Shields’s novel Swann. A Mystery (1987) by a Polish poet Ludmiła Marjańska (Zagadka wiecznego pióra, 1998). Marjańska’s translation is not an easy one to assess: it contains some shifts as well as simple mistakes, but Polish versions of lyrics quoted in the novel as written by a mysterious, unacknowledged (and non-existing) poet Mary Swann are undeniably its strongest point. What makes them more interesting, they show close affinity to poems by Emily Dickinson translated by Marjańska – and to her own poetry.

Authors: Marciniak Tomasz , Wiszomirska Ida , Ilnicka Lidia
Published: October 2018

Study aim: Assessment of postural stability performed on an unstable stabilometry platform. Comparison of the results ob­tained by two groups consisting of elderly (OW) (60+ years old) and younger women (YW).Material and methods: Seventy-three female volunteers were divided into two groups: 40 young women (20.2 ± 1.75), and 32 elderly women (68.3 ± 7.43). Participants performed five stability tests on Biodex Balance System SD: three 20-second tries, the Postural Stability Test (PST) and the Fall Risk Test (FRT). Three stability indexes - overall (OSI), anterior-posterior (APSI), and medial-lateral (MLSI) - both with eyes open (EO) and closed (EC) were analyzed. The impact of vision on balance was calculated as EC-EO. Also effect size was calculated and evaluated.Results: All of the parameters differed significantly between groups in favour of YW. The largest difference in significance as well as effect size was noted for FRT, p < 0.001 and 1.86 respectively. Tries measure the impact of vision on balance (EC-EO). The results concerning tries with EC-EO showed the strongest discrimination between groups - OSI p = 0.0088 (relative differ­ence 0.23 ± 0.26) and APSI p = 0.0268 (relative difference 0.17 ± 0.2). YW had a significantly better outcome.Conclusions: YW had better results in all of the parameters taken into consideration, with most of them being significant. This confirms that all of the regressive changes appearing with age influence balance. Lack of visual input (EC) in OW caused sig­nificantly worse results in most of the measured parameters, showing that vision is a very important factor for balance mainte­nance in the elderly.
Picturing an Impossible American: Njideka Akunyili Crosby and Photographic Transfers in Portals (2016)
Authors: Zelt Natalie
Published: October 2018

This article considers artist Njideka Akunyili Crosby’s use of photographic transfers and popular culture in her 2016 painting “Portals” to craft an artwork specific to her experience across multiple points of social identification in the United States and Nigeria. Through close reading and the study of Crosby’s formal and conceptual strategies, Zelt investigates how varying degrees of recognition work through photographic references. “Portals” contests assimilationist definitions of American identity in favor of a representation which is multiplicitous, operating across geographies. By juxtaposing images from different times, in different directions, Crosby constructs “contact zones” and provokes a mode of looking that reflects a feeling dislocation from the country in which she stands, the United States, and the country with which she also identifies, Nigeria. After a brief introduction to the artist and her relationship to Nigerian national politics, the article explores how distance and recognition work through image references to express a particular form of transnational identity, followed by an examination of uses of popular culture references to engage with blackness and an interdependent “Nigerian-ness” and “American-ness.” It concludes by contextualizing the painting’s display amid waves of amplified nativist purity in the US.

Between 1 Jan 2016 and 31 March 2016 a cross-sectional research study among visitors of the EMS clinics in the EMS of the Primary Health Services of Gorenjska was performed. The EUROPEP survey was used for rating the degree of patient satisfaction. Statistical methods were utilized to determine the differences among the studied variables, namely the t test, one way ANOVA, as well as post-hoc multiple comparisons, were used.

Results

Nearly all questions associated with the patient survey scored higher than 4.0, indicating patients were generally very satisfied with EMS treatment. Patients were least satisfied with the length of time spent waiting for an examination. The results showed that the waiting time is a statistically significant factor concerning all four dimensions of patient satisfaction: medical staff, clinical facilities, clinical equipment and organization of services (p < 0.05).

Conclusions

Research results have confirmed that the effectiveness of the EMS organizational model impacts on the degree of patient satisfaction. The research also revealed a deficiency in the current EMS organizational services at the prehospital level, given that triage frequently failed to be carried out upon a patient’s arrival at the EMS clinics.

Chronic subdural hematoma is a frequent type of hemorrhage, which terminates with mortality if not diagnosed and treated early. The aim of this clinical study is to evaluate the patients with unilateral and bilateral recurrent chronic subdural hematoma.

The study group consisted of 13 cases with unilateral and bilateral recurrent chronic subdural hematomas who underwent aggressive wide craniotomy, duraectomy, inner and outer membranectomy, dural border coagulation, incision through cortical vein trace and hang up of dural edge, between 2009 - 2016. All of our patients were diagnosed by preoperative Magnetic Resonance Imaging. We evaluated the age, gender, complaints and neurologic signs, localization and thickness of the hematoma.

We can estimate that wide craniotomy, duraectomy and membranectomy is a good option in preventing recurrent chronic subdural hematoma and complications.

Some results on abstract convexity of functions
Authors: Mohebi Hossein , Barsam Hasan
Published: October 2018

In this paper, we study abstract convexity topical and sub-topical functions. We obtain some results on abstract convexity such as support set and subdifferential in view of new elementary functions. Indeed, first we show that the ICR and IR functions are dense in IPH functions then the topical function and sub-topical function on topological vector space by another elementary function is studied. These elementary functions lead to obtain similar results with easier proofs.

Contribution of Agricultural Produce Spice Zingiber Officinale to a Sustainable Food System: Green Extraction and Stability Study of Antioxidant Compounds
Authors: Jaiswal Swapnil G. , Naik Satyanarayan
Published: October 2018

The present study has focused on the extraction and utilization of antioxidant compounds from the agricultural produce Zingiber officinale for its sustainable use in terms of stabilizing food from oxidation. Two extraction methods, traditional soxhlet and green supercritical CO2 (SC-CO2), were used to compare yields of antioxidant (6-gingerol) rich extracts. For the SC-CO2 method, operating parameters including pressure (10000-20000 kPa), temperature (30- 40°C) and CO2 flow rate (5-20 g/min.) were optimized to get maximum recovery of [6]-gingerol rich extracts. The results of the extraction study revealed that ginger extract collected after soxhlet extraction (GE1) gives more yield (3.85%) than the extract (2.41%) collected after SC-CO2 extraction (GE2) at an optimum condition of 20000 kPa pressure, 40°C temperature and 20 g/min. flow rate. Contrarily, the yield of [6]-gingerol was found to be greater in GE2 (389 mg/g) than GE1. Total phenol (TPC) and flavonoid (TFC) content of GE1 and GE2 were measured against equivalent concentrations of gallic acid and quercetin. TPC and TFC of GE1 show slightly higher values (38.50 mg GAE/g, 5.62 mg QE/g) than GE2. At the concentration of 3000 μg/mL, DPPH percent inhibition activity of GE1 was again higher (up to 94%) than GE2 (up to 82%). Stability study result of both GE1 and GE2 revealed on the basis of antioxidant indices, showed desirable antioxidant index by stabilizing all three experimented oils and also found to be comparable with synthetic antioxidants (BHA, BHT). Therefore, it could be concluded that [6]-gingerol rich extracts from the SC-CO2 method have comparable phenol flavonoid, antioxidant and stability potential as those found in ginger extracts from the traditional soxhlet method.
The Contribution of Migration to Economics Growth. Evidence from Spain
Authors: Mihi-Ramírez Antonio , Ojeda-González Sara , Miranda-Martel María José , Agoh Eugene
Published: October 2018

Productivity is crucial for economic growth. In a time of challenges such as the population ageing, a growing migration flows and slowdown of the economy it is very important to know the impact of migrant workers in productivity and development. Therefore, this paper studies relevant migration theories and the evolution of migration flows, productivity and their effect on economic growth. We analyse the contribution of immigrants’ workers to productivity, to the employment rate and to the demography of Spain in the last 10 years, a country where the last crisis deeply changes the migration patterns and economic conditions. The results show that, in this case, the impact of immigration on the level of development was small but positive.
