Hypokalemic periodic paralysis: an underestimated autosomal-dominant disease with variable phenotypic presentations
Authors: El-Reshaid Kamel , Al-Bader Shaikha
Published: May 2021

Periodic paralysis (PP) diseases are autosomal dominant disorders due to gene-mutations that manifests with episodic muscle weakness and/or paralysis.  Their mutations result in faulty ion-leaks that result in sustained muscle depolarization and inexcitability.  The group include; hyperkalemic PP, hypokalemic PP (HypoPP type I & II), normokalemic PP, thyrotoxic PP, Paramyotonia congenita and Andersen-Tawil syndrome.  The hypoPP is the most common disorder yet is underestimated in prevalence due to missed diagnosis mimicking hysterical disorders and neurological diseases as well as the hypokalemic syndromes (Bartter, Gitelman and renal tubular acidosis).  Moreover, and due to their considerable gene-penetrance, their phenotypic spectrum ranges from infrequent attacks to progressive muscular failure.  In this case report we present a patient with missed diagnosis for years and describe the algorithm of his diagnosis and management.

Published: May 2021

The imbalance between modulation of the cell proliferation and apoptosis results in abnormal cell production which ultimately leads to the cancerous condition. During the 21st century, cancer is probably exceeded to infectious and other chronic diseases as the major cause of death in all countries. The increasing global prevalence ratio and a speedily rising population of cancer survivors focus on the ferocity of public health and economic challenges pretended this disease. This review summarizes the significant outcomes of dietary intake which can enhance the immune response and reduce the risk of cancer. The nutritional general mechanism of action to influence the immune function and the potential activity of anticancer immunotherapy are also studied. For several cancers immunotherapy has developed into standard treatment but considerably remains to be done to prolong the activity of its potential efficiency mainly to cancers that are unaffected within each indication. Although a higher consumption of plant foods like vegetables, fruits, legumes, nuts and whole grains has been suggested for cancer prevention, it has been undecided what is the prime amount of ingestion of these foods and whether particular subtypes are valuable. Several million premature mortalities can be prevented if a high intake of plant foods is adopted globally. Furthermore, for reducing the risk of different types of cancers and slow down their development many dietary products have been proven advantageous.

Published: May 2021

Pulsed electric field therapy is a novel non-invasive approach for cancer therapy. It serves as a cell permeability enhancing agent for cancer treatment. Nanosecond, high-electrical field pulse power technology is used for delivering variable, controllable, intracellular electrical perturbations in several biological systems. Here, we investigated the effect of nanosecond (ns) electric pulse (nsEP) as a therapeutic tool for cancer. In in-vitro study, the breast cancer cells (MCF-7) were exposed with electric field of ~18kV/cm intensity, ~25ns duration, at 1.5Hz in a 2mm electroporation cuvette. Post exposure, observation shows a significant reduction in cell viability. It was evident that after treatment the viability of MCF-7 cancer cells at 630 pulses are remains ~38% only. The optical microscopic analysis of MCF-7 cells shows cell morphology changes after electrical pulse exposure. Moreover, we have also investigated a comparative study of the effect nano-second electrical pulses on MCF-7 cells and Chinese Hamster Ovary (CHO) cell line. The comparative study, demonstrated that the effect of nsEPF on MCF-7 is more destructive than on CHO cell line. The obtained results support that the pulse electrical field of nanosecond (ns) duration therapy would be a potential solution for cancer treatment.

AN OVERVIEW OF ENDOMETRIAL HYPERPLASIA
Authors:   Arulmigu Kalasalingam College of Pharmacy, Srivilliputhur, Tamil Nadu, India, Gokula Priya M
Published: May 2021

Endometrial Hyperplasia is referred as the endometrial cells of uterus, which keep on growing or multiplying instead of shedding because of high levels of estrogen and low or insufficient levels of progesterone. It is a pre-malignant condition but which are not invasive in nature. EH usually occurs in women between 50 – 55 yrs. Endometrium being a hormone dependent tissue depends on estrogen and progesterone for proliferation and shedding. Endometrial thickness gradually increases day by day. EH is caused by PCOS and chronic anovulation in premenopausal women. Obesity, lynch syndrome are other causes of EH. In 1994, WHO classified this EH into four groups. In 2014, WHO revised this classification into two types, one is endometrial Hyperplasia (without atypia) and second one is atypical endometrial hyperplasia or EIN. Patient with EH experiences abnormal uterine bleeding, bleeding in between periods etc… Age, nulliparity, obesity, smoking, diabetes mellitus are the risk factors and is diagnosed by endometrial biopsy, dilation, and curettage, a transvaginal ultrasound, hysteroscopy. Management of EH is based on its types. Hyperplasia without atypia is managed by the levonorgestrel-releasing intrauterine system (LNG-IUS), oral progestogens, and surgery. Atypical EH is managed by surgery hysterectomy

Authors:   Chaplygin Agricultural College, Tishaninov Igor
Published: May 2021

The level of soil compaction is influenced by physical and mechanical properties, climatic conditions, the amount of annual precipitation, the type of cultivated crops, and other factors. Excessive compaction of the soil impairs water permeability and air access to the roots, resulting in reduced crop yields, increased soil erosion, reduced fertilizer efficiency, which leads to an increase in the cost of material and technical resources for tillage. Therefore, it is important to solve this problem with minimal energy and material costs. Such a solution is the loosening of the soil, which can be done naturally and with the help of mechanical loosening. (Research purpose) The research purpose is in evaluating the effectiveness of loosening the soil with a U-shaped ripper at different angles of the ploughshare using fractal analysis methods, which is necessary to reduce additional loads during further soil treatment. (Materials and methods) A dirt channel with a special cart was used to consider physical models of meliorative machines and specialized working equipment. (Results and discussion) Author conducted six experiments in a soil tray for each corner of the ploughshare separately. Nineteen ground sections were made. The structure of the soil before and after treatment depends on the mode of operation of the ripper model and the design features of its working bodies. (Conclusions) The more energy is spent on the treatment of homogeneous areas, the more the soil structure changes. To quantify the structural changes in the nature of the cultivated soil, we used its fractal characteristics, in particular, the fractal dimension. The soil sections have fractal properties, and, accordingly, fractal methods can be used for their analysis. The article proves the applicability of fractal methods in the analysis of the quality of tillage and the degree of its loosening.

Published: May 2021

Most drying plants of small capacity for vegetables and fruits are convective without recirculation of the drying agent. Such dryers have a high energy consumption and cannot be attributed to energy-saving installations. (Research purpose) The research purpose is in developing a functional and technological scheme of an energy-eﬃcient thermoelectric dryer that provides a reduction in energy costs during the drying process while maintaining high quality indicators of the finished product and increasing the drying eﬃciency. (Materials and methods) The methods of system analysis and synthesis of existing knowledge in the field of research on the development of energy-saving dryers, based on the provisions of the theory of drying, heat and mass transfer and thermoelectricity were used. (Results and discussion) The article presents the structural and functional-technological schemes of a convective condensation dryer with recirculation of the drying agent based on Peltier thermoelectric elements. The technological process and the principle of operation of a convective dryer of the condensation type with the use of a thermoelectric assembly operating in the heat pump mode were described. The article proposes a general method for calculating the heat and energy parameters of the dryer based on the heat balance equation. The thermal energy withdrawn by the hot circuit of the thermoelectric assembly, and directed to heating the cooled and drained air, exceeds the energy consumed from the electrical network. The uniform transverse blowing of the drying box with an air ensures uniform drying of the product. (Conclusions) When the drying box is cross-blown and the air flow is relatively fast, the moisture evaporation process is accelerated, the drying time is reduced and the drying quality is improved. It was revealed using preliminary technical and economic calculations that the proposed design provides a reduction in energy consumption compared to traditional dryers by up to 25 percent.

Authors:   Saratov State Vavilov Agrarian University, Bakirov Sergey , Eliseev Sergey , Ryzhova Elena
Published: May 2021

In all operating conditions, electrified sprinklers are provided with energy from a centralized source or a portable diesel generator. The energy eﬃciency of these power supply methods is characterized by losses of electricity during transmission. Battery power sources of sprinkler machines are used in rare cases, there are no such machines on the agricultural lands of the Volga region. If the battery power source is installed next to the electric drive on a support trolley, then there is no loss of electricity during transmission and there is the possibility of using renewable sources, the cost of electricity is close to zero. (Research purpose) The research purpose is in evaluating the increase in the energy eﬃciency of a sprinkler machine with a battery power source and renewable energy sources in comparison with traditional energy supply. (Materials and methods) Authors used theoretical and empirical methods of scientific knowledge, namely mathematical analysis, systematic approach, literature analysis, observation. (Results and discussion) The power consumption of irrigation systems fed the cable line from the centralized grid will consist of the energy consumed by the actuators support trucks irrigation systems and the energy consumed for transmission. The increase in the energy eﬃciency of a sprinkler machine with a battery power source in comparison with a cable line consists in saving energy for transmission. Found that when comparing the line cable from the battery feeding method should take into account the losses in transmission of energy along the entire length of the construction of irrigation machines and energy loss during transmission from the transformer substation to the fixed support irrigation systems. (Conclusions) The energy loss along the length of the sprinkler machine logarithmically depends on the number of sections. In relation to the operating conditions of sprinklers in the Saratov region, it is possible to reduce energy consumption even without taking into account the starting modes from 0.20 to 2.01 percent for water distribution by circular sprinklers.

The article presents the data obtained as a result of an experiment on the distribution of the microwave field and the power dissipated in a dense grain layer at diﬀerent material humidity and waveguide configurations. The development of processing modes with the use of electrical technologies and electromagnetic fields will reduce the energy intensity and cost of grain heat treatment processes. When developing them, it is necessary to take into account the technological requirements for the processed material, the types of electrical technologies used, the operating mode of the intensifying equipment (constant, pulse, and others). (Research purpose) The research purpose is in experimentally evaluating the uniformity of the distribution of the microwave field in the zone of ultrahigh-frequency convective grain processing of a laboratory installation containing six sources of microwave energy. (Materials and methods) The article presents the scheme of the zone of ultrahigh-frequency convective treatment for the study; the factors considered in the experiment and the levels of their variation. (Results and discussion) An experiment was conducted to determine the coeﬃcient of uniformity of the propagation of the microwave field in a layer of grain material. The article presents obtained dependencies. (Conclusions) The results of the study of the microwave field strength in the grain mass can be used in the study of the dielectric properties of the processed grain, as well as in the construction of a control system for the design of ultrahigh-frequency convective processing plants. The values and patterns of changes in the uniformity coeﬃcient of the electromagnetic field distribution in the grain layer indicate a diﬀerence between the reference data on the dielectric properties of grain materials and their values for the layer of the processed material. The values of the uniformity coeﬃcient in the considered variants for a dense layer of wheat are in the range of 0.247713-0.426276.

Published: May 2021

At the heart of a micro-grid that includes several sources of electrical energy, including renewable energy, there must be a base (reference) source that sets the voltage and frequency in the network. (Research purpose) The research purpose is in developing a basic voltage source of a micro-grid, which includes renewable energy sources. (Materials and methods) The article shows that the sources of electrical energy are diﬀerent, but the main requirement for them is to be able to supply voltage to the electrical network at any time, there is a standard voltage scale in the network. For a micro-grid, which will include various sources of electrical energy with a total power of up to 25 kW, you can limit yourself to a voltage of 220 V and a single-phase electrical network. (Results and discussion) The article presents a block diagram; technical characteristics and electrical diagram of the inverter of a single-phase basic voltage source; a method for calculating the output filter of the inverter based on pulse-width modulation technology. (Conclusions) When using renewable energy sources in the micro-grid, it is necessary to take into account that there are periods of time in which they do not generate electrical energy and choose as the base one that will not have such moments, or you need to use a temporary electricity storage device. It is possible to use a chemical source or a battery of accumulators as a base source. When creating a micro-grid of alternating voltage, an inverter is added to these sources from constant voltage to alternating voltage. The article presents a block diagram of a base voltage source with an AC output reference voltage to create a micro grid with a power of up to 25 kW.

(Research purpose) The research purpose is in justifying a new method for developing deep high-temperature layers of the earth’s crust in order to obtain a hot coolant for petrothermal thermal power plants that provide heat and electricity supply systems for rural settlements and agro-industrial facilities. (Materials and methods) In rural areas where there are small cities, the population uses traditional hydrocarbon fuels for heat and electricity supply to the residential sector and public infrastructure: natural gas, fuel oil, diesel fuel, coal, which have a high cost and logistical losses. (Results and discussion) K.E. Tsiolkovsky described a method for obtaining thermal energy from the earth’s interior by drilling wells, heating the coolant and feeding it to the surface for further use. The hot layers of the earth’s crust are present throughout the land and sea areas of the world, but the temperature gradient in various places ranges from 2.5 to 4 degrees Celsius per 100 meters of depth. Petrothermal thermal power plants are cogeneration power plants, the efficiency of which can reach 80-85 percent and their location is possible in all climatic zones. (Conclusions) Petrothermal energy is an affordable source of thermal energy that can replace hydrocarbon fuels, nuclear energy, and low-efficiency solar and wind energy in Russia. In any small town or village that is cut off from centralized energy networks, it is possible to build a local thermal power plant that does not require the purchase of hydrocarbon fuel.

Published: May 2021

An analysis of the available automated indoor temperature control systems shows that all of them have a significant shortage. The systems do not provide for predictive temperature control in an automated form. Such changes are determined and made, depending on the qualification, by the operator based on personal experience and the reports received by him on the weather channels. Possible errors lead to loss of productivity or disruption of technological modes of production.

Sorting tomatoes by controlling their maturation is an important direction that characterizes the quality and marketability of tomatoes. Therefore, reliable control of the maturation of tomatoes is an actual and practically significant task. Currently, there are known methods of such control (RGB), based on determining the color of tomatoes. These methods have disadvantages, for example, insufficient reliability of monitoring the maturation of tomatoes of various (especially not contrasting in color) varieties, complexity and expensive equipment. (Research purpose) The research purpose is in proposing a new method of rapid sorting of tomatoes based on the control of the minimum (initial) level (Fo) of their rapid phase of chlorophyll fluorescence induction. The time of a single Fo measurement is from 0.01 to 0.07 seconds. (Materials and methods) The article presents mathematical models and conducted experimental studies for the fast phase of chlorophyll fluorescence induction, which confirmed the functional relationship between the maturation of tomatoes and their minimum (initial) level (Fo) of the fast phase of chlorophyll fluorescence induction. Authors used widely distributed botanical varieties of tomatoes "Alcazar", "Lezginka", "Rozanchik" with five stages of maturation (green, brown, pink, light red and red), for each of which we determined the key indicators of chlorophyll fluorescence induction: maximum (Fm), minimum (Fo), variable (Fv) values, the ratio of indicators (Fv/Fm). (Results and discussion) Chlorophyll fluorescence can be used to assess the maturation of tomatoes. As tomatoes ripen, the values of chlorophyll fluorescence parameters, such as Fo, Fm, Fv, and Fv/Fm, decrease. The article presents models that allowed us to estimate the stage of maturation of tomatoes for all three varieties. (Conclusions) The model that used both parameters of chlorophyll fluorescence was the best for three varieties of tomatoes.

Published: May 2021

Effective industrial rearing of pigs is impossible without providing them with full-value vitamin-enriched feed. The lack of vitamins in feed negatively affects the productivity of animals. One of the simple and affordable ways to increase the vitamin value of feed can be the addition of sprouted grain to the diet of animals. According to many scientists, when germinating in grain, the content of macro and microelements, vitamins increases. When using sprouted grains, the eatability of feed increases and the absorption of nutrients increases, because in the process of grain germination, enzymes are activated that convert complex nutrients into simple compounds that are easily assimilated in the body of young animals. The efficiency of germination and the quality of germinated grain depends on the conditions of germination and lighting conditions during the growing period. In addition, during long-term storage (more than 4-5 hours) of sprouted grain with a moisture content of more than 60 percent, it begins to mold and rot. Therefore, it must be fed in the first hours after germination. To extend the shelf life of germinated grain, it must be dried to the required moisture content. (Purpose of research) To study the effect of the duration of illumination on the germination rate and the chemical composition of germinated grain of soybeans and lupine. (Materials and methods) We studied the germination technology and, based on the data obtained, adopted our own germination method. An installation was made for determining the time of illumination of grain during germination. Chemical analysis of the composition of soybean and lupine grains was carried out before and after germination, as well as after drying. (Results and discussion) We compared the results of studies on the effect of lighting time on sprout length when germinating grain on vitamin feed. Determined the values of the rate of obtaining shoots, specific energy intensity of lighting. Studied the chemical composition of the original grain of soybeans and lupine, germinated and dried - separately and in stages. (Conclusions) When germinating soybean seeds, the average growth rate for 5 days was 3.34 millimeters per day, and for lupine seeds - 8.4 millimeters per day. In the samples of sprouted dried soybeans, an increase in crude protein in dry matter by 4.23 percent, crude fiber - by 2.07 percent, sugar content - by 0.48 percent was revealed. They showed that the amount of crude protein and crude fiber increased by 2.3 and 2.38 percent, respectively. It was noted that the content of calcium, phosphorus and sodium in the samples of soybeans and lupine increased slightly - less than 0.2 percent.

Sosnovsky hogweed is a dangerous weed that occupies large areas of agricultural land, negatively affecting their properties, as well as causing severe chemical burns. In the Tver region, thickets of hogweed are spread over a large area, and every year it spreads further and further. (Research purpose) The research purpose is in developing and testing the method of suppression of Sosnovsky hogweed, analyzing the results of laboratory tests of an innovative method for removing weed vegetation using the developed ultra-frequency emitter ISCh-19. (Materials and methods) Based on the analysis of the literature, authors found that there are five main methods of combating hogweed, but these methods are ineffective. The article describes an electromechanical method that includes irradiation of the weed, which contributes to its more effective destruction, and a device for controlling the roots and seeds of the plant. (Results and discussion) Authors assembled and installed a prototype of the ISCh-19 emitter in the educational and scientific laboratory of the Department of Technological and Transport Machines and Complexes of the Tver State Agricultural Academy on the soil channel. The roots that were at a depth of 0.2 meters under the radiation of 45 minutes, began to have a humidity of 1-3 percent, the tips of the roots closer to the surface were burned, converted into mineral fertilizer. (Conclusions) With an increase in the temperature of exposure to the soil, the viability of plant materials of Sosnovsky hogweed located in the soil decreases. The ISCh-19 is effective in the fight against Sosnovsky hogweed: the sown seeds were exposed to radiation, as a result of the experiment, the seeds did not germinate and the weed lost its viability. This device will help in the future to simplify the fight against Sosnovsky hogweed, allowing to stop its spread on agricultural soils.
Вертикальный город. Ретроспектива и современный этап развития многоярусной структуры городского пространства
Authors: Камалова Клавдия
Published: May 2021

Интенсификация функциональных процессов, поиски устойчивого развития высокоплотных урбанизированных территорий в противовес ограниченному земельному ре­сурсу всё чаще обращают внимание проектировщиков на концепцию «вертикального города». В основе его структуры лежит многократное тиражирование земельного участка с замещением территориальных зон на ярусы и распростра­нением общегородских процессов на подземный, наземный и надземный уровни, которые подразделяются по принципу функциональной принадлежности и могут включать не­сколько этажей. В рамках данной статьи в хронологическом порядке этапов формирования города рассматриваются примеры концептуальных идей и реализованных решений, планировочная организация которых опирается на много­ярусную структуру. Наиболее ярким воплощением данной концепции в архитектуре стал небоскрёб, функциониро­вание которого предполагает включение всевозможных процессов жизнедеятельности в пределы одной оболочки и игнорирование связей с уличным пространством и рядом стоящей застройкой. Катализатором многоярусного плани­рования городской структуры послужило хаотичное заво­евание наземного яруса автомобильным транспортом, место которому в различных утопиях отводилось и на крышах застройки, и на подземном уровне вместе с инженерными коммуникациями. Представленный анализ показал: наибо­лее уязвимыми в данном случае становятся горизонтальные связи, соединяющие автономные городские структуры и наземный уровень, приобретающий транзитный характер эксплуатации.

The сlassification of geosystem used in mapping is based on a system-hierarchic approach to detecting the co-involvement of landscape taxons. At the same time, we took into account the positioning of individual territories in the system of physical- geographical regionalization. The complexity of the landscape structure of the studied territory is due to its location at the junction of high- and lowland regions belonging to four physical-geographical areas. In the area under study, we identified and described more than 200 groups of fairies, which were then typed into classes of facies, geomes, and groups of geomes. Geoinformation mapping is performed using vector topographic basis and Earth remote sensing data. The decryption of synthesized space images was carried out manually and was based on field landscape surveys data. Digitization and indexing of landscape contours, creation, design and layout of the map were carried out in GIS MapInfo Professional. The cartographical analysis revealed regional differences in the complexity of landscape horizontal structures of high- and lowland regions, as well as the composition and structure of typological spectra of regional geosystems. Lowland geosystems mostly have a fairly uniform horizontal structure and large areas of landscape patterns. At the same time, mountain areas are characterized by considerable complexity and contrast of landscape structure.

Output-based Event-triggered Control of Networked Systems Subject to Bilateral Packet Dropouts

Published: May 2021

In this paper, an output-based event-triggered control problem of
discrete-time networked control systems (NCSs) subject to bilateral data
packet dropouts is investigated. In view of the stochastic sequences of
packet dropouts in measurement channels (from sensors to controller) and
control channels (from controller to actuators), the NCS is converted
into a closed-loop stochastic parameter system. In the aid of a Lyapunov
functional based on stochastic variables, sufficient conditions on
co-design of event-triggering strategy and exponentially mean-square
stability of NCSs are derived. Furthermore, an improved iterative
algorithm is given to obtain the dynamic output feedback control law and
event-triggering parameters from the nonconvex inequalities. Finally, a
numerical example and the corresponding simulation results are given to
show the validity and applicability of the developed techniques.
Spatiotemporal evolution of chlorophyll-a concentration from MODIS data inversion in the middle and lower reaches of the Hanjiang River, China
Authors: Chen zhuo , Dou ming , Xia Rui , Li Guiqiu , Shen Lisha
Published: May 2021

The global construction of water projects has led to a clear trend of
river and lake reservoir formation, spurring increasingly serious
ecological environmental deterioration, especially that caused by the
frequent occurrence of water blooms. Because of monitoring technology
limitations, monitoring the algae content index in water has lagged
behind the conventional water quality index, which makes sample
monitoring too sparse in many rivers and the monitoring data incoherent,
so it cannot truly reflect the evolution of water eutrophication. With
moderate resolution imaging spectroradiometer (MODIS) remote sensing
data monitoring, continuous chlorophyll-a observation data can be
collected effectively. This method has important guiding significance
for the early warning and control of water blooms. This study considers
the middle and lower reaches of the Hanjiang River in China, based on
the current remote sensing communication technology, MODIS remote
sensing data, and statistical methods and measured chlorophyll-a
concentration correlation analysis. Through the use of the trial and
error method to establish the band ratio model and BP neural network
model, two types of model errors were compared to determine the optimal
algorithm settings for the middle and lower reaches of the Hanjiang
River chlorophyll-a inversion. Subsequently, the algorithm model for
2000 to 2011 in the middle and lower reaches of the Hanjiang River
chlorophyll-a concentration inversion and the results of the inversion
analysis of spatiotemporal evolution characteristics we used to
determine the influence of various environmental factors on the
chlorophyll-a concentration change.
Ottimizzazione delle misure strumentali con sistemi IOMS per il monitoraggio delle emissioni odorigene in impianti complessi
Authors: Massimo Raffaele
Published: May 2021

Le emissioni odorigene generate da impianti industriali e di tutela
ambientale sono spesso causa di potenziali fenomeni di molestia
olfattiva in grado di generare malcontento nei cittadini che vi
risiedono in prossimità e, per tale ragione, vanno monitorate per
contenerle entro determinate soglie tramite azioni di controllo e
mitigazione. La caratterizzazione quantitativa e qualitativa dei
composti di tipo odorigeno risulta, tuttavia, ancora di complessa
esecuzione, sia a causa della soggettività intrinseca della percezione
olfattiva sia per effetto dell’influenza delle condizioni
meteoclimatiche sui fenomeni di dispersione odorigena e, dunque, sui
livelli di fastidio percepiti.

Fra le tecniche di misura generalmente impiegate per il monitoraggio
degli odori, quelle senso-strumentali con applicazione dei nasi
elettronici, più recentemente definiti IOMS (Instrumental Odour
Monitoring Systems), rappresentano attualmente la soluzione più efficace
per consentire l’investigazione della classe odorigena e dell’intensità
di odore e sono in grado di monitorare gli odori in maniera continua ed
in tempo reale, coniugando i vantaggi delle convenzionali tecniche di
misura strumentali e sensoriali. Gli IOMS rappresentano la tecnologia
con il più alto potenziale di sviluppo futuro e quindi risultano essere
dei sistemi ulteriormente migliorabili. La mancanza di riferimenti
tecnico-normativi in materia di emissioni odorigene rappresenta ancora
un fattore limitante per l’impiego di tali dispositivi. Il quadro
normativo in materia di odori, tuttavia, è in evoluzione, con
l’emanazione di norme e regolamenti in materia sia in ambito nazionale
che comunitario ed internazionale. La Norma UNI 11761:2019, in fase di
revisione, definisce i requisiti tecnici e di gestione degli IOMS per la
misurazione degli odori in aria ambiente, alle emissioni e indoor.
The Canadian Rangers: Cornerstone for Community Disaster Resilience in Canada’s Remote and Isolated Communities
Authors: Kikkert Peter , Lackenbauer P. Whitney
Published: May 2021

The Canadian Rangers are Canadian Armed Forces Reservists who serve in remote, isolated, northern, and coastal communities. Due to their presence, capabilities, and the relationships they enjoy with(in) their communities, Rangers regularly support other government agencies in preparing for, responding to, and recovering from a broad spectrum of local emergency and disaster scenarios. Drawing upon government and media reports, focus groups, and interviews with serving members, and a broader literature review, this article explains and assesses, using a wide range of case studies from across Canada, how the Rangers strengthen the disaster resilience of their communities. Our findings also suggest ways to enhance the Rangers’ functional capabilities in light of climate and environmental changes that portend more frequent and severe emergencies and disasters. It also argues that the organization can serve as a model for how targeted government investment in a local volunteer force can build resilience in similar remote and isolated jurisdictions, particularly in Greenland and Alaska.
