FORENSIC ASPECTS OF USING CERTAIN TECHNICAL MEANS OF ACTIVE SELF-DEFENSE
Authors: Bolshakov V. , Svytenko V. , Maznychenko Yu.
Published: June 2021

The article is devoted to the forensic aspects of ensuring necessary defense through the use by law enforcement officials of physical pressure of limited influence, special means (including non-lethal action) and firearms of increased efficiency.
The authors, based on the results of forensic practice, assessed the effectiveness of the actions of law enforcement officers to prevent the excess of necessary defense during covert investigative (search) activities.
A systematic analysis of recent studies and publications on this issue showed that in the modern global world, the main task of forensic support for law enforcement agencies in different countries is to optimize the processes of detecting, disclosing, investigating and preventing crimes and therefore contributes to the establishment of objective truth in criminal proceedings.
A sufficiently high level of criminalization of various spheres of life of modern society requires deep transformations in the system of preventive measures carried out by law enforcement agencies, government bodies and public organizations. The use of special forensic knowledge, along with other forms of preventive activity, can significantly enhance the prevention, detection, disclosure and investigation of crimes.
The preventive activity of forensic experts is to study and identify the causes and conditions conducive to the commission of socially dangerous acts. It is noted that Hungarian scientists consider the issues of crime prevention and operational-search activity to be the subject of forensic science.
The international experience of disclosing, investigating and preventing crimes indicates a significant number of unsuccessful investigative actions due to the incompetent use of firearms and active defense equipment.
It is concluded, based on the content of the concepts of disclosure, investigation and prevention of crimes, and taking into account the historical experience of forensic research of means of necessary defense and firearms, that it is necessary to develop forensic recommendations. In order to increase the efficiency of covert investigative (search) actions by law enforcement officers through the use of modern means of necessary defense and means of physical influence of limited action, as well as special types of non-lethal police weapons with improved characteristics.

Age and correlation of supracrustal rocks in the Frederikshåbs Isblink area
Authors: Dawes P.R
Published: June 2021

Eight weeks field work was spent in the Frederikshåbs Isblink area as a continuation to the investigations carried out in 1967. Half the time was used to further the work on Dalagers Nunatakker and half was spent on the gneisses and supracrustal rocks north of the Isblink in an attempt at correlation across the Isblink between the gneiss-amphibolite complex of the Frederikshåb area (see Jensen, 1966) and the Ravns Storø region (Windley et al., 1966; Windley, 1968).
K/Ar age determinations on dolerites from southern Peary Land
Authors: Henriksen N , Jepsen H.F
Published: June 2021

Whole rock K/Ar age determinations have been undertaken on two Precambrian discordant sills and one post Lower Cambrian dyke from the Jørgen Brønlund Fjord - Midsommersø area. The rocks, which were collected by H. F. Jepsen, were chosen for age determination to obtain a minimum age of the pre-tillitic sandstones in southern Peary Land and from this to get an indication ofthe age of the youngest sedimentation in the Carolinidian geosyncline (Haller, 1961).
The composition of sands from the Fiskenæsset region, South-West Greenland, and its bearing on the bedrock geology of the area
Authors: Kalsbeek F
Published: June 2021

A study of sand samples has shown that most of the material of the sands has only undergone short transportation and that their composition gives a good impression of the composition of the rocks in the area. Therefore, the study of sands may be used for prospecting and for regional geochemical studies in this part of Greenland. Eighty-six sand samples were studied. Most of the sands were taken from river beds and minor streams and contain 45-60 vol. % of plagioclase, 20-35 vol. % of quartz, 5-20 vol. % of dark minerals and less than 15 vol. % of potash feldspar. Hypersthene occurs especially in the northern part of the area, and the amount gradually decreases towards the south. The bulk composition of the rocks seems to be much the same throughout the whole area.

(samples marked I). The dates are expressed as uncorrected C14 years based on the conventional half life for C14 of 5570 years. In the dating of bivalve shelIs the surface material of the shelIs has been removed prior to analysis.
Discordant U-Pb isotopic system in zircons from a granite north-west of Frederikshåbs Isblink, Fiskenæsset region
Authors: Pidgeon R.T
Published: June 2021

Extensive sampling was carried out in parts of the Fiskenæsset region during the 1971 field season with the aim of providing suitable matenal for isotopic age determinations. The total area covered by the mapping programme was so large and the geological problems so varied that it was decided to initiate this study by looking in detail at a small number of rock types in one or two sub-areas. Once isotopic relationships are known in these areas it is hoped to extend the work to embrace other problems in the region. The laboratory work is in progress at present and already some preliminary results have been obtained (Feb. 1972).It is the purpose of this report to discuss the age relationships of zircons extracted from a single 100 kg sample of granite from the mapping area of Hopgood (see plate 1).
The chemistry of the Fiskenæsset complex on Qeqertarssuatsiaq
Authors: Windley B.F
Published: June 2021

Rock and mineral analyses arranged in stratigraphic order through the Fiskenæsset complex provide a basis for discussing its geochemistry, a summary of which is given here. Eighteen XRF whole rock analyses made at Leeds University have been used by Windley, Herd & Bowden (in press) to determine the way-up of the intrusion and to provide preliminary bulk geochemical trends. One hundred and twenty eight mineral analyses made with the ARL electron probe at Chicago University by Windley & Smith (in press) have been used to determine cryptic variation trends in the intrusion and to establish distribution pattems of elements within major phases and between coexisting phases.
Preliminary results of the mapping of the Tertiary basalts in western Nûgssuaq
Authors: Hald N
Published: June 2021

The purpose of the investigations during the summer of 1971 was partly to map the Nûgssuaq peninsula west of the Itivdle valley and partly to continue the collecting of rocks for a petrological description of the upper lava formation on Nûgssuaq and Hareøen (Hald, 1971).
Results of investigation of Tertiary volcanic breccia south of Niaqornat, Nûgssuaq, West Greenland, 1971
Authors: Philip P
Published: June 2021

On the Nûgssuaq peninsula, south of Niaqornat village and east from the northerly extension of the Itivdle valley, there lies an area in which Cretaceous and Danian sediments are overlain by igneous rocks. These rocks in the main are highly altered, ultrabasic breccias. Further east basalt flows cap the high ridges. The area visited was the high ridge between the valley Tunorssuaq and the north coast, east and west of Niaqornat village. In particular considerable attention was given to the area described by Arnold Heim (1910, p. 209) 4 km south-west of Niaqornat village. Heim was the first to discover these rocks and classified them as intrusive mainly because of the graphitisation of some of the shales nearby. This idea was continued by Rosenkrantz (in Birkelund, 1965, plate 49), Rosenkrantz & Pulvertaft (1969, p. 892) and Henderson (1969 a, p. 20; 1969 b, p. 25).
Investigations on the Nagssugtoqidian boundary between Holsteinsborg and Kangâmiut, central West Greenland
Authors: Bridgwater D , Escher A , Nash D.F , Watterson J
Published: June 2021

The southern boundary of the Nagssugtoqidian mobile belt was first mapped by Noe-Nygaard & Ramberg (1961) on the basis of the progressive deformation of a swarm of basic dykes - the Kangarniut dyke swarm. Field work in 1969 showed this boundary to have an approximate NE-SW strike (Eseher et al., 1970). The object of the summer's field work reported on here was to continue the investigations along the Nagssugtoqidian boundary and to study the deformation- metamorphism-dyking relationships in the western part between Holsteinsborg and Kangamiut. The field work formed part of a joint project involving the University of Liverpool. Transport in the field was supplied by the GGU cutter "A. Kornerup" with Orla Norsk as skipper.

Published: June 2021

The season's field work on the Ilímaussaq intrusion was overshadowed by the disappearance of one of the investigation team, Laust Løkkegaard, who following a day in the field, failed to return to base-camp Dyrnæs. In a subsequent search members of the team, helped by volunteers from Narssaq and by helicopter and fixed-wing aircraft, failed to locate Løkkegaard. This tragic event occurred in the beginning of August.
Review of the Survey's activities in 1973
Authors: Ellitsgaard-Rasmussen K
Published: June 2021

The Geological Survey of Greenland (GGU) is the official govemment department of the Ministry for Greenland responsible for scientific and practical investigations of all geological matters relating to Greenland. In Greenland the main activities in 1973 were geological mapping, ground and airbome geophysical work, glaciological and hydrological projects, as well as visiting economic sites for the Ministry for Greenland leading to advice on affairs conceming concession rights. Interest in the economic potential of Greenland's bedrock has remained high. The Survey has dealt with matters concerning the radioactive resources of Greenland together with environmental and pollution aspects in connection with the exploitation of resources. Accordingly the chemistry laboratory has been expanded both in personnel and instrumentation resulting in a marked increase in analytical capacity. Additional departments dealing with ore geology, technicai geology and geochemistry have been planned. In preparation for the mapping of the large areas of sedimentary rocks in North Greenland, the Survey employed in 1973 its first full-time palaeontologist. It was not possible to continue the marine geophysical programme started in 1973 but marine and airbome geophysical surveys form an important part of planned future work. Increasing attention will be paid to the continental shelf of Greenland, an area of approximately 60 0000 km2, particularly in respect of the hydrocarbon potential.
Notes on some Lower Palaeozoic to Tertiary faunas from eastern North Greenland
Authors: Peel J.S , Dawes P.R , Troelsen J.C
Published: June 2021

The north-east 'corner' of Greenland is geologically probably the least known region in North Greenland. Various expeditions have visited the coastal parts but geological detail, particularly faunal information, has remained surprisingly scarce. Initial field work by Koch (1923, 1925) and Troelsen (1949a, b, 1950) showed that a Precambrian to Silurian section - unfolded in the south, folded in the north - was unconformably overlain by a Carboniferous to Tertiary section, now referred to as the Wandel Sea basin (Dawes & Soper, 1973).
Untraditional topographic mapping in central West Greenland
Authors: Dueholm K.S
Published: June 2021

During the geological investigations carried out in central West Greenland (see Schiener, this report) a cartographical programme was carried out to test a newly developed method of producing topographic maps direct from aerial photographs. The programme was adapted to the working conditions of the geologists and the author was attached to different geological parties working on western and central Nugssuaq, southern Disko, Hareøen and Ubekendt Ejland. Within the two months' season sufficient measurements were obtained to enable eventual topographic map coverage of 1700 km2 with acceptable accuracy for geological mapping at the scale 1:50 000.

As a part of the mapping of the Quaternary deposits for a map sheet in 1:500 000, covering Søndre Strømfjord to Frederikshåbs Isblink, key areas in the region between Ravns Storø and Ameralik fjord were investigated in the period 24th June to 25th August.
A seismic and gravity study of the western part of the Cretaceous-Tertiary sedimentary basin of central West Greenland
Authors: Elder J.W
Published: June 2021

In the summer of 1972 a GGU seismic group working on land measured the thickness of sediments in the western part of the Nugssuaq peninsula, West Greenland, by explosion reflection and refraction seismic methods. In the region crudely bounded by Ikorfat, Ubekendt Bjland and Hareøen Cretaeeous-Tertiary sediments extend about 1-3 km below sea level and rest on the granodioritie gneiss basement. The basin shallows gradually toward the west where it is sharply hidden beneath Tertiary basalts. There is strong evidence for continuity of the Cretaeeous-Tertiary sediments aeross Umanak Fjord as far as Ubekendt Bjland. The most distinctive feature of the basement strueture is a ridge, running roughly N-S through the western part of the area, and rising about 2 km above the deeper parts of the basin. This ridge appears as a northerly continuation of the Disko gneiss ridge. The gravity pattern over a 100 km X 50 km strip centred on the western part of the basin shows rapid westward thinning of the earth's crust, and suggests that the basin has its origin in an incompletely rifted structure marginal to the crustal rifting responsible for Baffin Bay.
1:500 000 mapping of the Thule district, North-West Greenland
Authors: Dawes P.R
Published: June 2021

Field investigations aimed at the produetion of a 1:500 000 map sheet of the Thule distriet were continued during August and early September. The unusuaIly poor weather conditions and the premature arrival of the winter's snowfall, reduced the season to some 20 effective working days. The field work was in two parts. At the beginning of the season a Jet Ranger helicopterwas chartered at Thule Air Base and four days were spent investigating nunatak and inland areas north of Savigsivik and Kap York and at the heads of Wolstenholme Fjord, Olrik Fjord and Inglefield Bredning. The second part was an investigation ofthe Proterozoic Thule Groupon Herbert ø, Northumberland Ø and Hakluyt Ø. Transport for this phase wasa locally hired boat from Avatak Henson of Moriussaq. Certain logistic support was supplied to H. R. Cooke who visited the Thule district at the end of the field season to assess the economic potential of various minerallocalities. Kurt Thomsen ably assisted both in Cooke's and the author's field programmes.

On 8th April 1975 the Ministry for Greenland granted 13 concessions to explore for and exploit petroleum to six groups consisting of 19 foreign companies and one Danish consortium. The concessions comprise 46 blocks with a total area of 19 082 km2 (fig. 9).
Airborne radiometric survey between 66° and 69°N, southern and central West Greenland
Authors: Secher K
Published: June 2021

An airborne radiometric survey was initiated in central West Greenland in 1975 folIowing completion of the aeroradiometric work in East Greenland (Nielsen, 1972; Nielsen & Larsen, 1974). During, 1975 the region between Søndre Strømfjord and Jakobshavn Isfjord was covered, an area of c. 58 000 km2. The programme was carried out as a collaboration between GGU and the Danish Atomic Energy Commission's Research Establishment, Risø. GGU and Risø each supplied three participants. The aircraft, a Britten-Norman Islander, were chartered through Greenlandair Charter AIS. Aeromagnetic measurements were carried out simultaneously (Thorning, this report). Field operations were carried out from Søndre Strømfjord Air Base. It is planned to continue this radiometric survey duiing the next few years, including follow-up fieldwork on the ground.
Systematic mapping of the Archaean basement in the Fiskenæsset region, southern West Greenland
Authors: Kalsbeek F
Published: June 2021

The systematic mapping of the Fiskenæsset region, which began in 1970 (see previous GGU Report of Activities) was completed between June and September 1975. The work was hampered by relatively poor weather. Apart from the writer, the folIowing geologists took part in the field work: J. C. Escher (GGU), J. S. Myers (GGU), O. Stecher (Århus University) and J. Tomas (Geo!. Surv. Prague). R. T. Pidgeon (Scottish Universities Research Reactor Centre, East Kilbride) collected more material for isotope work, and H. R. Cooke (GGU) made a brief survey of the chromite deposits. Much of the work of this summer consisted of checking previously mapped areas and of correlating rock types between different parts of the region.
Review of the Survey's activities in 1976
Authors: Ellitsgaard-Rasmussen K
Published: June 2021

In 1976 the first petroleum exploration well was drilled on the shelf off West Greenland. This marked an important stage in the development of petroleum exploration in Greenland folIowing the granting of concessions in April 1975 by the Ministry for Greenland. GGU's Oil and Gas Section was closely involved in the assessment of the drilling programme and in following the operation. Sample material and data were submitted during and after the drilling to the Ministry for Greenland and were studied in the Survey as part of the follow-up procedure. Several members ofthe GGU staff visited the drill ship Pelican during the summer.

Published: June 2021

The folIowing account identifies and discusses the microfauna. and microtlora from samples of Upper Carboniferous limestone collected from Hellefiskefjord in eastern Peary Land (fig. 4) by J. C. TroeIsen during 1949 when a member of the Danish Peary Land Expedition (1947-1950). The samples were obtained from a section ofIimestones and shales which, as far as currently known, comprises the basal unit in the Hellefiskefjord llfea ofthe Wandel Sea Sedimentary Basin (Peel et al., 1974). The age ofthe samples is considered to be Late Pennsylvanian (Late Virgilian?), confirming the suggestion made by TroeIsen (1950) on the basis of the occurrence of Triticites.
Cambrian-Silurian studies in Washington Land, western North Greenland

Published: June 2021

The geological programme commenced in Washington Land during 1975 (Henriksen & Peel, 1976) was continued at an amplified level during July and August 1976 when parties from the Geodetic Institute and the Institute for Surveying and Photogrammetry, Technical University of Denmark, joined three groups from GGU in a combined operation. The natural landing strip at the eastem extremity of Cass Fjord (fig. 10) again served as a base camp, but parties worked throughout Washington Land with supportfrom a Greenlandair Charter Bell 204 helicopter periodically travelling north from Thule Air Base.
Investigations of the sediment thickness in Søndre Strømfjord, West Greenland
Authors: Larsen B
Published: June 2021

Søndre Strømfjord, approximately 170 km long, is a very clear example of a fjord formed by glacial processes. The bottom of the outer part ofthe fjord is U-shaped and situated only a few tens of metres below sea level. In the inner half of the fjord, north-east of Sarfartoq, the fjord is about 280 m deep and the sea bottom nearly horizontal for at least 40 km. In the innermost part the bottom rises towards the large glacial river near the air base (data from Danish nautical charts nos. 1410, 1411, 1412).

Project Westmar, A shallow marine geophysical survey on the West Greenland continental shelf
Authors: Brett C.P , Zarudzki E.F.K
Published: June 2021

An extensive shallow geophysical survey has been carried out on the West Greenland continental shelf between 64° and 69°30'N. Preliminary interpretation of the data reveals that between 64° and 67°30'N at least, the entire shelf was glaciated to its western margin during the Pleistocene, the glaciation processes leaving a variable (< 20-200 m thick) cover on the Tertiary sedimentary wedge underlying the shelf. A morphological relationship exists between the degree of sea floor roughness and the types of glaciation forms. The distribution and contacts of the three main shallow bedrock units in the area (Precambrian gneisses, Lower Tertiary volcanics and Tertiary sediments) are delineated. Widespread prograding is observed in sediments along the shelf margin. Extensive iceberg scouring of the sea floor is observed north of 67°30'N reaching a maximum water depth of 340 m.
Cambrian - Middle Ordovician stratigraphy of the Adams Gletscher region, south-west Peary Land, North Greenland
Authors: Peel J.S
Published: June 2021

Previous geological descriptions of the Adams Gletscher region (fig. 9) have been given by J. C. Troelsen (unpublished field notes in GGU) and Dawes (1976) - the latter based on a three day reconnaissance during 1975. The sequence contains a much fuller record of the Cambrian system than is present in the geologicaIly better described area near Jørgen Brønlund Fjord to the east (Christie & Peel, 1977; Jepsen, 1971), where only Lower Cambrian strata are present. A sample with trilobites collected by Dawes established the occurrence of Middle Cambrian rocks near Adams Gletscher (Peel in Dawes, 1976), but it would now appear that a substantial part of the sequence is of this age. In addition, the location in 1978 of early Late Cambrian trilobites near the base of a 900 m thick unit overlain by the Wandel Valley Formation of Early-Middle Ordovician age, suggests that the upper sub-division of the Cambrian is also well represented. An unconformity of regional extent separates the Cambrian from the overlying Wandel Valley Formation. This formation maintains the same generallithology at Adams Gletscher as that described by Christie & Peel (1977) to the east, although a tentative lithologicallink to the late Lower Ordovician of western North Greenland is established.

ProtowenelIa is aminute planispiral mollusc with characteristic circumbilical channels on the internal mouid, first described from two Middle Cambrian localities in Australia by Runnegar & Jell (1976). BergMadsen & Peel (1978) subsequently described Protowenella from the Middle Cambrian of Denmark and, on the basis of a functional morphological interpretation, supported the suggestion of Runnegar & Jell that the genus was a member of the class Monoplacophora.
Mapping in the Umanak district, central West Greenland
Authors: Pulvertaft T.C.R
Published: June 2021

Publication of 1:100000 geological maps from central West Greenland has reached a stage when five maps have been issued, and a sixth is in an advanced stage of preparation. However, until the summer of 1978, one of the most readily accessibie areas in this part of Greenland - that around and east of Umanak - had not been mapped in greater detail than required for the production of the 1:500000 sheet Søndre Strømfjord - Nfigssuaq. Consequently it was decided that the writer, together with a group of senior students from the Institute of General Geology, Copenhagen University, should remap the area over a period of three seasons with a view to preparation of the 1:100000 sheet 70 V.2 Nord - Agpat. This work was started in the 1978 field season when in all four geologists, each with an assistant, were in the fieid. The areas in which the individual geologists worked are shown in fig. 9. Mapping was carried out on enlargements of vertical aerial photographs provided by the Geodetic Institute, the 1:50000 topographic sheets being unsuitable for detailed mapping. Logistic support was provided by the GGU cutter N. V. Ussing, with Flemming Nielsen as skipper.

The purpose of the summer's field work was twofold: (a) to search for native iron and sulphide mineral assemblages in the northem extension of the Kitdlit dyke (Fundal, 1975; Pedersen, 1977a & 'a' in figs 10 & 11) and other related (sediment contaminated) dykes, and (b) to map the surrounding area as a contribution to the map sheet Diskofjord (69 V. 1 N, fig. 2). About 600 km2 were mapped in detail and 1500 km2 briefly surveyed.
Regional modelling of ablation in West Greenland
Authors: Braithwaite R.J
Published: June 2021

Regional assessment of water resources in West Greenland is needed in connection with planning future hydropower projects. Ablation from the Inland Ice and from local glaciers will be an important water source in most basins and a simple model for computing specific ablation has been developed. The model uses air temperatures extrapolated from coastal weather stations and will be eombined with areal data from the West Greenland glacier inventory to give estimates of runoff due to ablation for individual basins. The model is found to somewhat underestimate ablation at lower altitudes whilst greatly overestimating at higher altitudes and work will continue to improve the model. However, the present model applied to the Nordbogletseher in Johan Dahl Land indieates that the standard deviation of the ablation is about a quarter of the long-term mean which suggests that runoff rneasurements would have to be made for many years at the Nordbosø to obtain a reliable mean value for the runoff from the glacier.
Sr-isotopic studies and mineral composition of the Hagen Bræ Member in the Proterozoic clastic sediments at Hagen Bræ, eastern North Greenland
Authors: Larsen O , Graff-Petersen P
Published: June 2021

During the field season of 1978, siltstones from the Hagen Bræ Member of the Proterozoic Independence Fjord Group were sampled for isotopic dating by John Collinson (Collinson, this report). The samples were collected from the north side of Hagen Bræ along two profiles separated by approximately 800 m (Collinson, 1979 and this report, fig. 8, locality B). The total thickness of the siltstones from the unconformity below the siltstone beds to the feldspathic sandstone above is approximately 40 m. The samples appear to represent the lower third of the member.

Phương pháp này đã được ứng dụng rộng rãi để giải các bài toán mà không yêu cầu đòi hỏi phải tìm được nghiệm chính xác, bởi ngay từ dữ liệu đầu vào của bài toán có thể đã là dữ liệu xấp xỉ. Vì vậy tìm được thuật toán xấp xỉ giải bài toán có chi phí thời gian tính toán thấp mà vẫn đảm bảo độ chính xác theo yêu cầu là mục tiêu của bài báo này cần đạt được. Theo cách tiếp cận này, chúng tôi xây dựng được thuật toán có độ phức tạp về thời gian tính toán là đa thức khi bài toán được xét trong không gian Euclide và nghiệm tìm được có độ chính xác chấp nhận được.

Lào Cai, một tỉnh miền núi phía Tây Bắc, có tiềm năng lớn về phát triển du lịch và khai thác khoáng sản để phát triển kinh tế xã hội. Là một tỉnh giáp với Trung Quốc, hàng năm Lào Cai vẫn phải mua điện từ nước bạn. Hơn nữa, do đặc thù dân cư còn thưa thớt, các cơ quan công sở của Lào Cai có không gian khá rộng, số giờ nắng vào mùa hè khá cao. Do vậy, để giảm tải cho nguồn điện hóa thạch trong nước đang dần cạn kiệt và ít lệ thuộc hơn vào nguồn điện mua từ Trung Quốc. Việc xây dựng các trạm điện năng lượng mặt trời tại Lào Cai nói riêng và ở Việt Nam nói chung là hết sức cần thiết, phù hợp với chủ trương của Chính phủ. Hiện nay, việc phân phối và lắp đặt các trạm điện năng lượng mặt trời không còn xa lạ. Tuy nhiên, ở Việt Nam phần lớn các bộ Inverter và hòa lưới đều được nhập từ nước ngoài. Việc sử dụng, bảo hành, bảo dưỡng các sản phẩm này còn lệ thuộc nhiều vào hãng. Bài báo này trình bày kết quả nghiên cứu để tạo ra một hệ thống điện năng lượng mặt trời mang thương hiệu Việt. Sản phẩm có tính năng tương đương một số hàng nhập ngoại nhưng vẫn làm chủ được công nghệ và thiết bị. Kết quả mô hình phần cứng được lắp đặt thử nghiệm tại 3 địa điểm khác nhau tại thành phố Lào Cai với tổng công suất lên đến 20 KW.

Ротова рідина є важливим біологічної середовищем, а її хімічні і фізичні властивості безумовно впливають на стан зубів та слизової оболонки порожнини рота. Доведено, що серед чинників ризику розвитку карієсу зубів у дітей вагома місце займає соматична патологія. Бронхіальна астма є одним з найбільш поширених захворювань у структурі хронічної патології дихальних шляхів серед дітей, яке вимагає застосування ІГКС і бета -2- агоністів короткої та тривалої дії, що безумовно впливає на гомеостаз ротової порожнини. Тому метою нашого дослідження було визначити фізичні властивості ротової рідини (рН, буферну ємність, в'язкість ротової рідини а також об’єм слиновиділення) у дітей з бронхіальною астмою. Для вивчення концентрації іонів водню (рН), буферної ємності і в'язкості та об’єму слиновиділення ми провели дослідження ротової рідини у 70 дітей віком 7, 12 і 15 років за допомогою наборів тест-системи Salivа Сhеck Buffer (GC). Встановлено, що рh ротової рідини у дітей з бронхіальною астмою, в середньому, становить (6,49 ± 0,10), що нижче в порівнянні з практично здоровими дітьми (7,10±0,10). Така ж тенденція спостерігається відповідно буферної ємності ротової рідини: 5,89±0,19 у дітей з бронхіальною астмою проти 6,98±0,12 у практично здорових дітей. Щодо в'язкості ротової рідини виявлено протилежні результати, а саме, збільшення кількості дітей з підвищеним рівнем в'язкості у дітей з бронхіальною астмою в порівнянні з практично здоровими дітьми. Встановлено зниження об’єму слиновиділення у дітей з бронхіальною астмою у порівнянні з дітьми групи контролю (5,94±0,25 мл проти 9,26±0,38 мл відповідно, р<0,001).Таким чином, у дітей з бронхіальною астмою встановлено наявність карієсогенної ситуації в порожнині рота внаслідок зниження рН і буферної ємності а також рівня слиновиділення і підвищення в'язкості ротової рідини.

The general objective is to be able to know the impact that has been generated in the establishments with operations in foreign trade derived from the contingency COVID-19. Therefore, the review is done from the perspective of knowing the state of Mexican and Guanajuato companies that have foreign trade as an activity, which sector they belong to, which of them manage foreign trade programs such as IMMEX, and that it is important to highlight their impact as well. On the other hand, important data such as the results of the National Institute of Statistics and Geography (INEGI) are considered, such as the fact that 17% of the economic units in Mexico with international trade transactions are macro companies and concentrate 82% of the value of foreign trade of manufacturing companies, just as foreign trade represents approximately 65% of the GDP and exports about 30% in recent years. Therefore, it is concluded that the pandemic achieved great changes by which, Mexicans instead of taking it as an economic stoppage, quickly took it as an opportunity to create micro-enterprises achieving in this way opportunities, as well; it changed the way countries relate to each other and how governments face the problem on a daily basis, but it can be stated that neither international trade nor foreign trade stops, because they are part of an activity that determines the survival of world economies and without which life today could not be conceived. In this way, it is expected that in the following years; products will be exported to different countries, generating an increase in wealth within Mexico, as has been shown in the last semester of 2020 with the increase of Mexican exports.
