Dengue Fever and Severe Dengue in Barbados, 2008–2016
Authors: Douglas Kirk Osmond , Dutta Sudip Kumar , Martina Byron , Anfasa Fatih , Samuels T. Alafia , Gittens-St. Hilaire Marquita
Published: May 2020

Analysis of the temporal, seasonal and demographic distribution of dengue virus (DENV) infections in Barbados was conducted using national surveillance data from a total of 3994 confirmed dengue cases. Diagnosis was confirmed either by DENV–specific real time reverse transcriptase polymerase chain reaction (rRT–PCR), or non–structural protein 1 (NS1) antigen or enzyme linked immunosorbent assay (ELISA) tests; a case fatality rate of 0.4% (10/3994) was observed. The dengue fever (DF) prevalence varied from 27.5 to 453.9 cases per 100,000 population among febrile patients who sought medical attention annually. DF cases occurred throughout the year with low level of transmission observed during the dry season (December to June), then increased transmission during rainy season (July to November) peaking in October. Three major dengue epidemics occurred in Barbados during 2010, 2013 and possibly 2016 with an emerging three–year interval. DF prevalence among febrile patients who sought medical attention overall was highest among the 10–19 years old age group. The highest DF hospitalisation prevalence was observed in 2013. Multiple serotypes circulated during the study period and Dengue virus serotype 2 (DENV–2) was the most prevalent serotype during 2010, whilst DENV–1 was the most prevalent serotype in 2013. Two DENV–1 strains from the 2013 DENV epidemic were genetically more closely related to South East Asian strains, than Caribbean or South American strains, and represent the first ever sequencing of DENV strains in Barbados. However, the small sample size (n = 2) limits any meaningful conclusions. DF prevalence was not significantly different between females and males. Public health planning should consider DENV inter–epidemic periodicity, the current COVID–19 pandemic and similar clinical symptomology between DF and COVID–19. The implementation of routine sequencing of DENV strains to obtain critical data can aid in battling DENV epidemics in Barbados.

Published: May 2020

Dengue Hemorrhagic Fever (DHF) in Indonesia has increased steadily with Bandung as a hyper-endemic area holding a high number of cases for years. This study aimed to identify cluster areas and their correlation with land use changes which was indicated by changes of Normalized Difference Vegetation Index (NDVI). Hospital surveillance of 28,327 cases during 2008–2013 was geo-coded into sub-district levels and analyzed to find cluster areas over time and space using SaTScan and ArcGIS. Spearman correlation was used to analyze NDVI with Incidence Rate (IR) in each area. IR of DHF cases tended to increase over 6 years during high precipitation period. Cases were concentrated in several cluster areas in 2009 then moved to eastern part of the city in 2013. NDVI had negative correlation with IR in 2008 (r = −0.258; p = 0.001) and positive correlation in 2012 (r = 0.193; p = 0.017). Clear geographical pattern by cluster identification overtime is beneficial for targeting appropriate vector-control program.
On the Non Metrizability of Berwald Finsler Spacetimes
Authors: Fuster Andrea , Heefer Sjors , Pfeifer Christian , Voicu Nicoleta
Published: May 2020

We investigate whether Szabo’s metrizability theorem can be extended to Finsler spaces of indefinite signature. For smooth, positive definite Finsler metrics, this important theorem states that, if the metric is of Berwald type (i.e., its Chern–Rund connection defines an affine connection on the underlying manifold), then it is affinely equivalent to a Riemann space, meaning that its affine connection is the Levi–Civita connection of some Riemannian metric. We show for the first time that this result does not extend to general Finsler spacetimes. More precisely, we find a large class of Berwald spacetimes for which the Ricci tensor of the affine connection is not symmetric. The fundamental difference from positive definite Finsler spaces that makes such an asymmetry possible is the fact that generally, Finsler spacetimes satisfy certain smoothness properties only on a proper conic subset of the slit tangent bundle. Indeed, we prove that when the Finsler Lagrangian is smooth on the entire slit tangent bundle, the Ricci tensor must necessarily be symmetric. For large classes of Finsler spacetimes, however, the Berwald property does not imply that the affine structure is equivalent to the affine structure of a pseudo-Riemannian metric. Instead, the affine structure is that of a metric-affine geometry with vanishing torsion.
Long Live the Heritage of Petroleum—Discoveries of Former Oil Sites in the Port City of Dunkirk
Authors: Hauser Stephan J.
Published: May 2020

In the early days of the petroleum industry, oil infrastructure had a short lifespan. Individuals were creating their own company and competing with others, without the financial means of current great companies. Many oil facilities were established in port cities like Dunkirk, because they were the entrance gates to many nations. In the case of Dunkirk, many former oil sites became houses and schools in the current urban tissue, and official records lost track of many others. The limited data available on official records to inform the people on the pollution of their soil is a threat to their safety and health, and an obstacle for the planning strategies of public authorities. The analysis of archival documents, past and present aerial pictures, paintings and mapping techniques related to geographic information systems (GIS) can reveal lost industrial sites, and thus indicate potential pollution. This paper investigates the oil history of Dunkirk as a background for its petroleum history and its transferability to other petroleum related cities. A cross analysis of sources will attempt to complete French files and locate oil sites. The objective is to illustrate the transformation of former oil sites, and why the current land use is often not compatible with its history.
Feline Morbillivirus, a New Paramyxovirus Possibly Associated with Feline Kidney Disease
Authors: Choi Eun Jin , Ortega Victoria , Aguilar Hector C.
Published: May 2020

Feline morbillivirus (FeMV) was first isolated in stray cats in Hong Kong in 2012. Since its discovery, the virus has been reported in domestic cats worldwide, including in Hong Kong, Japan, Italy, US, Brazil, Turkey, UK, Germany, and Malaysia. FeMV is classified in the Morbillivirus genus within the Paramyxoviridae family. FeMV research has focused primarily on determining the host range, symptoms, and characteristics of persistent infections in vitro. Importantly, there is a potential association between FeMV infection and feline kidney diseases, such as tubulointerstitial nephritis (TIN) and chronic kidney diseases (CKD), which are known to significantly affect feline health and survival. However, the tropism and viral entry mechanism(s) of FeMV remain unknown. In this review, we summarize the FeMV studies up to date, including the discoveries of various FeMV strains, basic virology, pathogenicity, and disease signs.
Host Protective Immune Responses against Influenza A Virus Infection
Authors: Jung Hi Eun , Lee Heung Kyu
Published: May 2020

Influenza viruses cause infectious respiratory disease characterized by fever, myalgia, and congestion, ranging in severity from mild to life-threating. Although enormous efforts have aimed to prevent and treat influenza infections, seasonal and pandemic influenza outbreaks remain a major public health concern. This is largely because influenza viruses rapidly undergo genetic mutations that restrict the long-lasting efficacy of vaccine-induced immune responses and therapeutic regimens. In this review, we discuss the virological features of influenza A viruses and provide an overview of current knowledge of the innate sensing of invading influenza viruses and the protective immune responses in the host.
The Outcome and Economic Viability of Embryo Production Using IVF and SOV Techniques in the Wagyu Breed of Cattle

Published: May 2020

The Japanese black cattle breed (Wagyu) has an improved metabolism, which allows them to have a higher marbling score when compared with other cattle breeds. However, this may affect other aspects of the animal’s physiology, including hormone secretion and their reproductive success, such as their response to synchronization protocols and embryo production. Therefore, the objectives of this study were to test a superovulation protocol (SOV) developed with low doses of FSH and to evaluate the outcome and economic viability of embryo production using the SOV and in vitro fertilization (IVF) approaches in the Wagyu cattle breed. For that, ten Wagyu cows were submitted to five SOVs over a period of 15 months using a standard protocol: CIDR + 3 mg estradiol benzoate (D0), 35 mg FSH (Folltropin®) a.m. and p.m. (D4), 35 mg Folltropin® a.m. and 20 mg p.m. (D5), 20 mg Folltropin® a.m. and 10 mg p.m. (D6), 10 mg Folltropin® and 0.5 mg cloprostenol, both a.m. and p.m., + CIDR removal (D7), 0.05 mg GnRH + insemination 12 and 24 h after (D8) and embryo collection + 0.5 mg of cloprostenol (D16). Thirty days after each SOV, a follicular aspiration was conducted to produce IVF embryos without any pre-synchronization using standard semen in the same group of animals. The average number of embryos produced was 7.63 ± 5.61 (SOV) and 4.52 ± 2.44 (IVF) (p = 0.303). There was no significant correlation between the number of embryos produced by the different techniques (SOV and IVF), indicating that cows that respond well to SOV did not respond well to IVF and vice versa (r = 0.379, p = 0.529). The total cost of each embryo produced by SOV was R$215.00 and R$410.00 for IVF. Therefore, cows that produce less than five embryos by SOV are not economically viable due their lack of response to FSH, and the use of IVF in those animals may be more effective.
Kultūriniai lietuviškumo vaizdiniai Aušroje ir moksliniai kontekstai

Published: May 2020

The article analyses cultural meanings of images of Lithuanianness, as
represented in the publications of the first illegal Lithuanian newspaper
Aušra (published 1883 to 1886), and their relation to scientific contexts.
The past and language and daba (culture) are considered as thematic fields
and sources of images that participate in creating the Lithuanians’ story of
‘themselves’. Their instrumental capacities are different, although the 19thcentury
proto-disciplinary integrity of linguistics, history, ethnology and
anthropology justifies their implicit interconnectedness. The article also
suggests that images of forest and hill-fort encompass the idea of social and
cultural evolution, and the understanding of culture as being dynamic.

Key words: image of Lithuanianness, symbolic structure, scientific knowledge,
theory of evolution, the Lithuanians’ story of themselves.

Authors: Najjari Abbas , Shayesteh Kamran
Published: May 2020

Hazardous wastes include various types of chemicals and other wastes generated from industrialand other sources. Because of the complexity of waste management systems, the selection of theappropriate solid waste landfill site requires consideration of multiple alternative solutions andevaluation criteria. This paper investigated the utilization of the fuzzy logic in combination withAnalytic Hierarchy Process (AHP) technique by applying GIS and IDRISI programming for choosinghazardous waste landfill site in Nahavand, Iran. Based on the real conditions of the study area, weconsidered economic, biological and topographical factors (12 criteria). The candidate sites weredetermined based on the criteria weights. The best location was determined via the fuzzy logic andthe AHP methods. This study found that the combination of fuzzy logic and the AHP method was thebest option for selecting a site for hazardous waste landfill. In the end, 6 suitable areas were selectedfor a hazardous waste landfill in the city. This study verified that the combination of the AHP methodwith fuzzy logic using GIS in our project is a powerful tool for solid waste landfill site selection.

Authors: Jamalian Marjan , Shaygannejad Vahid , Sedehi Morteza , Kheiri Soleiman
Published: May 2020

Background and aims: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system. The impact of the number of attacks on the disease is undeniable. The aim of this study was to analyze the number of attacks in these patients. Methods: In this descriptive-analytical study, the registered data of 1840 MS patients referred to the MS clinic of Ayatollah Kashani hospital in Isfahan were used. The number of attacks during the treatment period was defined as the response variable, age at diagnosis, sex, employment, level of education, marital status, family history, course of disease, and expanded disability as the explanatory variables. The analysis was performed using zero-inflated negative binomial model via Bayesian framework in OpenBUGS software. Results: Age at diagnosis (CI: -0.04, -0.20), marital status (CI: -0.56, 0.002), level of education (CI: -0.81, -0.26), Job (CIHousewives vs Employee=[0.04, 0.64], CIUnemployee vs Employee=[-1.10,0.008])), and course of disease (CI: -0.51, -0.08) had a significant effect on the number of attacks. In relapsing-remitting patients, the number of attacks was partial significantly affected by expanded disability status scale (EDSS) (CI: -0.019, 0.16). Conclusion: Aging, being single (never married), high education, and not having a job decrease the number of attacks; therefore, lower age, being married, primary education, and being a housewife increase the number of attacks. An interventional or educational program is suggested in order to prevent the occurrence of further attacks in high-risk groups of patients and to increase their chances of recovery.
Increased oil recovery from Halfdan chalk by flooding with CO2-enriched water: a laboratory experiment
Authors: Olsen Dan
Published: May 2020

Injection of CO2 is a method that may increase the recovery of oil from Danish chalk reservoirs in the North Sea. The method is used elsewhere, particularly in North America, but has so far not been used in the North Sea and has nowhere been used for chalk reservoirs, and the performance of the method when used for North Sea chalk is therefore uncertain. A laboratory flooding experiment was conducted at the Geological Survey of Denmark and Greenland on a sample from the Nana-1X well of the Halfdan oil field in the Danish North Sea in order to test the efficiency of CO2-enriched water to produce additional oil from chalk. The sample is a low-permeability chalk from the Ekofisk Formation and represents rocks that are marginal to the Halfdan reservoir in an economical sense.

Published: May 2020

The Triassic – lower Cretaceous sedimentary succession of the Norwegian–Danish Basin has for a long time been of exploration interest, and numerous studies have been carried out. However, high-resolution correlation within the basin remains necessary, especially between the Danish and Norwegian parts of the basin. A variety of litho- and biostratigraphic schemes have been applied to the succession over the years, but lack of consistency in terminology has often led to confusing interpretations of the geological development. In this study a sequence stratigraphic scheme has been developed for the Danish Basin and a compiled palynological event stratigraphy is applied to a number of wells connecting the Danish and Norwegian parts of the basin and new marker horizons are identified. One of the aims of this study is to reach consistency in order to facilitate correlation within the basin and we also emphasise the recognition of a potentially important mid-Triassic event in the basin.

Published: May 2020

In 2008, the Geological Survey of Denmark and Greenland began a project in collaboration with the Bureau of Minerals and Petroleum of Greenland with the aim to publish a web-based, seamless digital map of the Precambrian bedrock between 61°30´ and 64°N in southern West Greenland. Such a map will be helpful for the mineral exploration industry and for basic research. Producing an updated digital map requires additional field work revisiting key localities to collect samples for geochemistry, geochronology and metamorphic petrology. The new data will help us to test and refine existing models and improve general understanding of the geological evolution of the area. Here we summarise some results from the 2008 field activities between Ame - ralik in the north and Frederikshåb Isblink in the south (Fig. 1). The area was mapped in the 1960s and 1970s, and although the 1:100 000-scale maps are of excellent quality, they do not include more recent developments in geochronology, thermobarometry and geochemistry. A notable exception is the Fiskenæsset complex (Fig. 1), which has received considerable attention after it was first mapped (Ellitsgaard-Rasmussen & Mouritzen 1954; Windley et al. 1973; Windley & Smith, 1974; Myers 1985). New tectonic models have been developed since the original 1:100 000 maps were produced, and the tectonic evolution has been com - monly ex plained in terms of terrane accretion (Friend et al. 1996).
Developing a 3-D model for the Skaergaard intrusion in East Greenland: constraints on structure, mineralisation and petrogenetic models
Authors: Nielsen Troels F.D. , Olsen Símun D. , Stensgaard Bo M.
Published: May 2020

The Skaergaard intrusion (Fig. 1) is probably the most studied layered gabbro intrusion in the world (Wager & Deer 1939; Wager & Brown 1968; McBirney 1996; Nielsen 2004). The intrusion is c. 54.5 Ma old and was formed during the Palaeogene opening of the North Atlantic Ocean, intruding into the base of the East Greenland flood basalts. The intrusion is relatively small with a volume of c. 300 km3 (Nielsen 2004). Spectacular magmatic layering and systematic evolution in the compositions of liquidus phases and estimated melt compositions (e.g. Wager & Brown 1968) have made the intrusion the most studied example of the development of the ‘Fenner trend’ of iron enrichment in basaltic liquids (e.g. Thy et al. in press; Veksler in press).

Published: May 2020

The tendency in recent years to improve worldwide agricultural production has opened the door to innovative research techniques to prevent diseases, pests, and negative consequences due to climate variations in crops. This study aims to develop an acquisition system using the embedded BeagleBone Black and the DHT 22 sensor, which allow measuring the physical parameters of temperature and relative humidity; these were registered in a database that was created in MySQL. The system was implemented within a greenhouse crop; additionally, a mobile application was developed, written in Kotlin language, to facilitate monitoring the physical parameters of temperature and relative humidity remotely, so that farmers can collect valuable information about their crops wherever they are. This development was carried out using a client-server structure, making use of free software and hardware, which makes for a low-cost, easily-implemented system for farmers. The monitoring system worked as expected, and the information obtained was reliable. The results show that the implementation is useful in greenhouse agriculture and that, through digital innovation, effective agricultural practices can be improved which could increase production and decrease costs, making use of modern technologies.
GENERAL STRUCTURE OF TILLAGE DRAFT FORCE. CONSEQUENCES IN EXPERIMENTAL AND APPLICATIVE RESEARCHES
Authors: Cardei P. , Muraru S.L. , Sfiru R. , Muraru V.
Published: May 2020

The empirical and theoretical estimation of the draft force of agricultural machinery for soil tillage, has been the target of scientific research for about one hundred years. The results obtained so far may seem contradictory or divergent. The article presents the results of some research on the usual calculation formulas of the draft force of agricultural machines for soil tillage. Although apparently these formulas are different, analyzing the structure of the formula, we find cohesion and coherence embodied in a simple generalization and easy to use both theoretical and experimental. Moreover, the formulas are convertible between them, the two languages used for their definition (the mechanics of deformable solids and that of the phenomenological description), are only different forms of expression for the same phenomenon. Another problem that is addressed in the research whose results are presented in this article is that of highlighting the dependence of the draft force on the tool speed (in the field) of the soil tillage machine. Exposure is complemented by an algorithm that highlights the dependence of the draft force on the tillage tool speed. Also like a consequences of the draft tillage force structure, finally, a third problem addressed in these researches and whose results and perspectives are given in this paper is that of optimizing the working processes of agricultural machinery for soil tillage. The treatment of the problem starts from the hypothesis of the most general formula of the traction resistance force and proposes some ways to solve the optimal problem.

Car and motorcycle vehicles are vital needs in this modern era to help someone to a certain place. Inevitably the increasing number of cars and motorbikes with fewer roads to accommodate these vehicles results in congestion or long queues that are so crowded. So the government also conducted several methods to unravel congestion, including traffic engineering. This method can be said to be successful if congestion in an area can decrease from usual. However, not every successful traffic engineering, even congestion is getting worse. Therefore we need to test the results of traffic engineering. One of them is using the M/M/1 queuing model with Poisson distribution and then simulated by SimEvents in Matlab. As researchers, we can also provide solutions to unravel these bottlenecks. The traffic engineering that we are going to analyze is Cipaganti traffic engineering, Bandung. Keywords:queue; traffic engineering; SimEvents; cipaganti.

Registration may be an elementary task in image process wont to match 2 or a lot of photos taken, as an example. CAN are investigated as a general-purpose answer for image version problems. Such systems were not just taking in the mapping from input picture to yield picture, yet additionally, gain proficiency with a misfortune capacity to mentor this mapping. Such things make it possible to use a similar kind of generic approach to traditional types of problems which requires very less or different loss formulations. We also show that the approach used here is very effective for image synthesizing from the label maps, and also we reconstruct the objects from edge maps, and colorizing pictures, among different errands. To be sure. Further showing its wide materialness and simple selection without the requirement for parameter tweaking. As a network, it's never again a hand engineer for our mapping capacities and with the assistance of this we can accomplish powerful result without hand-designing our misfortune work.

But cloud computing maintain the distributed environment for storing the data which increase the risk of data leakages. A suitable solution to reduce the security risk is to deploy encryption mechanism. Ensuring security on cloud storage is still a challenging issue. In this paper a hybrid encryption techniques is proposed with three powerful algorithms such as Advanced Encryption Standard, Rivest–Shamir–Adleman (RSA) and MD5. The Encryption scheme executes between the fragmentation and replication process. The proposed hybrid framework strength the security of cloud data. If any successful attacks occurs the attackers does not able to discover the plaintext. The implementation was carried out with the help of Clousim framework. The performance of this study is compared with prior encryption techniques.

Watermarking is a technique to ensure the original information and to validate the digital content. Watermarking is required because of the rise in the utilization of the internet in one's everyday life. As the usage of digital content is developing quickly, there are numerous occurrences where information is uncertain. Watermarking is a procedure to conceal information for authorization reasons. Watermarking is the ideal approach to make sure about the digital content. Watermarking should be possible through different strategies. Least Significant Bit Watermarking (LSBW) strategy is one of them. Right now, pixel estimations of the image are changed over into binary. The data is covered in the bits of the pixel esteems. Watermarking consistently infers embedding of furtive signal that should be robust and imperceptible within the host data. In order to cater its robustness and imperceptibility, the energy of the watermark is accommodated to the energy of speech components.

In today trendy world hybrid based optimized data clustering is unique and imperative clustering tool in the area of data mining, which is dynamic research of actual creation problems. The oldest and furthermost commonly used popular clustering technique is the K-means(KM) algorithm, which is very complex and for the initialization of the cluster centroid and it will easily go for premature converge. This initialization problem of K-means can be evaded by built in boost function of K-Harmonic Means, which is centroid based clustering algorithm and also unresponsive for collection of initial partition clustering , but it can easily go for pre-matured conjunction in local optima. To avoid this convergence problem, this proposed algorithm uses Boosting K-harmonic means(KHM) algorithm with BBO to produce more precise, robust, better clustering solution in few number of iterations, evade conning in local optima and simply convergence to relate with Harmonic Means, BBO algorithms. Biogeography based algorithm works with the concept of emigration and immigration of inhabitants from one location to another location, Which has high computation cost. For avoiding this high computation cost in this hybrid optimization technique Biogeography-Based Optimization (BBO) is integrated with K-Harmonic means algorithm to produce optimum and effective clustering solution with faster convergence. BBO is universal optimization methods to solve utmost of the optimization problem, which is an production based generation of evolutionary algorithm (EA)that augments a function by stochastically and repeatedly improving the clustering solution of quality, or fitness function. The experimental results of this paper shown as the projected method is very resourceful and faster to afford better clustering solution in less number of repetitions for medical data.

В статье рассмотрен исторический аспект возникновения иконографических знаков как средства выражения семантического и коннотативного значения при передаче информации, проведено сопоставление их с современными средствами невербальной коммуникации.
С целью выявления вектора дальнейшего использования невербальных средств коммуникации прослежена динамика развития невербальных средств коммуникации в социальных сетях в период 1990–2019 годов. Отмечен значительный пропорциональный перевес в процентном отношении средств невербальной коммуникации по сравнению со средствами вербальной коммуникации при передаче той или иной информации. На основе анализа невербальных средств коммуникации и их применения в социальных сетях интернета в статье поднимается проблема систематизации и научного подхода к использованию невербальных средств с целью упрощения пользования. Необходимость упрощения вызвана ускорением темпа коммуникации в социальных сетях и увеличением количества графических символов для обозначения оттенков того или иного сообщения, придания ему нужной степени коннотативности. В результате увеличения количества символов наблюдаются затруднения при их выборе и правильной оценке его коннотативного значения.

Синонимия — один из главных видов лексической парадигматики, один из самых фундаментальных типов семантических отношений в лексической и словообразовательной системе языка. Синонимия свойственна лексической, фразеологической, грамматической, словообразовательной системам языка.
Автор данной статьи анализирует парадигматические связи синонимии с антонимией, многозначностью, семантической и словообразовательной производностью в словообразовательном гнезде, а также применение лингвистами разных критериев при описании синонимии, стремящихся дать исчерпывающие определения понятия «синоним», в которых одни считают обязательным критерием синонимичности слов обозначение ими одного и того же понятия, а другие исследователи берут за основу выделения синонимов их взаимозаменяемость.
В статье также основное внимание уделено определению понятия и критериев функциональной грамматической синонимии, обоснованию подходов к выделению номинативных и функциональных грамматических синонимов и описанию синонимических парадигм, разработке понятия синонимического ряда, его структуры и вариативности, установлению системных связей функциональных грамматических синонимов в их соотнесённости с семантическими полями, возможности взаимозамены и нейтрализации значений синонимов в определенных контекстах.

В работе исследовали эффективность распада полисахаридов пшеничных отрубей кислотным и ферментативным способами. Проведен сравнительный анализ биотрансформации растительных полимеров нативных и механически активированных пшеничных отрубей мультиэнзимными комплексами: амилолитического, глюколитического и целлюлолитического действия. С целью модификации белковых компонентов пшеничных отрубей использовали композицию ферментных препаратов амилолитического и протеолитического действия. Количественный и качественный состав моно-и дисахаридов в полученных гидролизатах определяли методом ВЭЖХ, содержание аминного азота - методом Попе-Стевенса. Установлено, что при высокотемпературном химическом гидролизе полисахаридов образуется высокий уровень пентоз - 62,4 мг/г сырья; увеличилось общее содержание моно- и дисахаридов до 125,6 мг/г пшеничных отрубей. При ферментативном методе обработки как нативных так и механически обработанных пшеничных отрубей комплексом препаратов: ГлюкоЛюкс А (1 %), АмилоЛюкс АТС (0,5 %), ЦеллоЛюксА (0,5 %) определено наибольшее суммарное содержание моно- и дисахаридов - 215,2 и 216,8 мг/г отрубей соответственно, что выше в 1,7 раза в сравнении с композицией ферментов протеолитического действия. Установлено содержание аминного азота при биоконверсии комплексом ферментных препаратов Протеаза кислая и Биоферм составила 39,52 мг/г сырья.

В работе изучена фунгицидная активность препарата Биопаг при осеннем опрыскивании клубней. Целью исследований явилось изучение влияния осенней обработки клубней препаратом Биопаг на микробиологическое состояние клубней и потери от болезней, а также выявление наиболее эффективных доз препарата, обеспечивающих максимальный защитный эффект при хранении картофеля. Для обработки использовали клубни двух сортов картофеля одной группы спелости (раннеспелой) – Жуковский ранний и Ред Скарлет. Обработку клубней осуществляли через две-три недели после уборки путем опрыскивания их из малообъемного опрыскивателя ПУМ-30 МК раствором препарата в дозировках 0,5 л/т; 075 л/т и 1,00 л/т. Контролем служили клубни, обработанные водой. После обсушивания клубни закладывали на хранение в отдельный закром модульного картофелехранилища. Температура в основной период хранения составила 4-6°С, относительная влажность воздуха – 85-90%. Состояние поверхностной микрофлоры клубней оценивали дважды – перед закладкой на хранение (сентябрь) и в конце хранения (апрель); количественные потери клубней от микробиологических болезней учитывали в конце хранения. При этом использованы стандартные методы исследований. После 7 месяцев хранения установлено улучшение микробиологического состояния обработанных клубней по сравнению с контрольными. Особенно эффективно действие Биопага против таких потенциально опасных для человека микроорганизмов, как дрожжи и плесени. В среднем за два года выявлено снижение по отношению к контролю потерь от микробиологических болезней клубней на 0,11-8,69% в зависимости от сорта и дозировки препарата. Максимальный защитный эффект вызывает дозировка препарата 0,75 л/т.

Объектом исследований служили корнеплоды инфицированной слизистым бактериозом сахарной свеклы, клеточный сок и полуфабрикаты свеклосахарного производства. Цель исследований заключалась в установлении закономерностей изменения качества технологических соков при введении ферментного препарата гликозидазного действия в процессе экстрагирования сахарозы из бактериально инфицированной сахарной свеклы. Теоретически обоснованы предпосылки применения гликозидазных ферментных препаратов при переработке бактериально инфицированной сахарной свеклы. На основе физического и математического моделирования процессов экстрагирования сахарозы и известково-углекислотной очистки диффузионного сока выявлены зависимости изменения технологических показателей от дозы введения гликозидазного ферментного препарата и степени инфицированности слизистым бактериозом клеточного сока сахарной свеклы. Показана роль ферментативной обработки в улучшении качества технологических соков, в том числе увеличении содержания сахарозы в очищенном соке в среднем на 2,2%, повышении эффекта очистки диффузионного сока в среднем на 3,5%, снижении мутности очищенного сока – на 20%, что может обеспечить повышение качества и выход белого сахара на 1,1%. Достигнуто требуемое состояние пищевой системы с оптимальными (максимальными) показателями величины коэффициента желательности от 0,63 до 0,99, что соответствует хорошему и очень хорошему уровню в зависимости от степени инфицированности корнеплодов. Дальнейшие исследования будут направлены на обоснование условий рационального применения ферментных препаратов гликозидазного действия в оптимальной комбинации совместно с другими технологическими вспомогательными средствами при экстрагировании сахарозы из бактериально инфицированной сахарной свеклы.
