Мета дослідження – оглянути точку зору фірм, що пропонують викопне паливо, на теорію загального надбання людства (theory of global commons). Спільне надбання людства охоплює сфери і ресурси, що виходять за рамки національних юрисдикцій. Тим не менш, на даний момент їх управління здійснюється національними державами. Дизайн/Метод/Підхід. В данній статті запропоновано підхід до загального надбання людства з точки зору фірм. Результат: На сьогоднішній день компанії взаємодіють з національними державами щодо емісії вуглекислого газу і, ймовірно, міжнародних схем торгівлі квотами на емісію. Розглянута теорія пропонує перенести відповідальність національного рівня на міжнародний рівень управління, тобто на Організацію Об'єднаних Націй. Теоретичне значення дослідження: При зміщенні механізму контролю в бік палива, що надходить в економіку, більшість компаній (крім видобувних компаній) зможуть сконцентруватися на тому, на чому вони і повинні концентруватися – на задоволенні потреб своїх клієнтів. Компанії ж, що видобувають викопне паливо, будуть зобов'язані купувати права на емісію палива до того, як це паливо потрапить в економічний цикл. Даний підхід створить економічний стимул для компаній застосовувати технології з низьким або нульовим рівнем споживання викопного палива і дозволить зробити перехід від викопного палива легко планованим. Таким чином, запропонований механізм може називатися іммісійною схемою (від латинського immissio, "впускати"). Оригінальність/Цінність: Управління спільним надбанням людства на рівні національних держав є мало прийнятним, а також не відображає природу використовуваних ресурсів. Дана стаття пропонує одне з рішень проблеми глобальної зміни клімату. Перспективи подальших досліджень. Буде потрібно дослідження застосованості даної схеми до різних видів промисловості, а також у прив'язці до різних типів викопного палива. Тип статті – теоретична.
Цель исследования – рассмотреть точку зрения фирм, предлагающих ископаемое топливо, на теорию общего достояния человечества (theory of global commons). Общее достояние человечества охватывает сферы и ресурсы, выходящие за рамки национальных юрисдикций. Тем не менее, их управление осуществляется на данный момент национальными государствами. Дизайн/Метод/Подход. В данной статье предложен подход к общему достоянию человечества с точки зрения фирм. Результат: На сегодняшний день компании взаимодействуют с национальными государствами касательно их эмиссии и, вероятно, международных схем торговли квотами на эмиссию. Развиваемая теория предлагает перенести ответственность национального уровня на международный уровень управления, то есть на Организацию Объединенных Наций. Теоретическое значение исследования: При смещении механизма контроля в сторону топлива, поступающего в экономику, большинство компаний (кроме добывающих компаний) смогут сконцентрироваться на том, на чем они и должны концентрироваться – на удовлетворении потребностей своих клиентов. Компании же, добывающие ископаемое топливо, будут обязаны приобретать права на эмиссию топлива до того, как это топливо попадет в экономический цикл. Данный подход создаст экономический стимул для компаний применять технологии с низким или нулевым уровнем потребления ископаемого топлива и позволит сделать переход от ископаемого топлива легко планируемым. Таким образом, предлагаемый механизм может называться иммисионной схемой (от латинского immissio, “впускать”). Оригинальность/Ценность. Управление общим достоянием человечества на уровне национальных государств является мало применимым, а также не отображает природу используемых ресурсов. В данной статье предложено одно из решений проблемы глобального изменения климата. Перспективы дальнейших исследований. Потребуется исследование применимости данной схемы к различным видам промышленности, а также в привязке к различным типам ископаемого топлива. Тип статьи – теоретическая.
Purpose. This conceptual paper takes the firms’ perspective about practical implications of the theory of the global commons. Global commons are the areas and resources defined as those being beyond national jurisdictions. Their governance, today, however, is still coordinated largely by national states. Design/Method/Approach. This paper introduces a firm's perspective based on the global commons approach. Findings. At present, companies deal with national governments concerning their emissions and, perhaps, the international emissions trading scheme. Theory argues about the need to shift the responsibility from the national to global governmental levels, i. e. the United Nations. Theoretical implications. Given the input orientation put forward by this approach, companies – except fossil fuel extractors – would not actually have to deal with any governmental or regulatory bodies but can focus their capabilities on what they are best at: serving the needs of their customers. Fossil fuel extracting companies, in order to sell these fossil fuels, will have to purchase the amount of emission rights before they sell the fuel into the economic cycle. This approach establishes an economic incentive for companies to employ technologies with low or zero fossil fuel consumption while making the transition path predictable. The underlying concept, therefore, can also be referred to as an immissions scheme (from Latin immissio, “to let in”). Originality/Value. Governing a global common through national structures is inappropriate and does not reflect the nature of the underlying resource. This paper proposes a solution to the problem of global climate change. Further research. Further research is needed to address the effect of this strategy on different industries, and how those are affected based on the degree to which they employ fossil fuels. Paper type – сonceptual.

Opis:
In man, as well as in many species of vertebrates there exist several populations of Giardia duodenalis group which, though morphologically indistinguishable, show different level of heterogenicity in several characteristics, a. o. in surface antigens, isoenzyme make-up, RFLP, invasiveness for different hosts or pattern of experimental infection. Also the clinical observations in man distinctly suggested that G. intestinalis comprises several different populations. In the course of giardiosis apparent variability in clinical manifestations can be observed. In many patients the infection is symptomless and resolves spontaneously and in some others – variable intensity of symptoms is observed. Most likely both the parasit's characteristics and the host's feature will determine the clinical character of infection. It is well known that in some cases it is the host that responsible for the symptoms of the infection. Thus, for instance, clinical giardiosis links with immunodeficiency, malnutrition or young age. There are also evidences that some Giardia isolates have enhanced potency to provoke the disease of the host. It is considered that the variable pattern of the infection may be related to three different factors in host-parasite relationship: extra- and intrapopulation variability of Giardia isolates, the microenvironmental factors of the host's intestine, and the variable immune response of the host. The author describes data on the two first factors.

Opis:
The present study proposes a class of product-type exponential estimators for estimating the population mean of the study variable, using known values of some population parameters of an auxiliary character, under the simple random sampling without replacement (SRSWOR) scheme. Furthermore, the study also proposes a modified exponential estimator based on both the ratio-type and the product-type exponential estimators. Properties of the proposed estimators, under the SRSWOR scheme, are obtained up to first order approximation. The modified exponential estimator under optimum conditions is shown to be more efficient than the simple sample mean and the ratio-type and product-type exponential estimators. The theoretical results are supported by an empirical illustration.

Opis:
Status and correlation of Andean ammonite biozones are reviewed. Available calpionellid, nannofossil, and radiolarian data, as well as radioisotopic ages, are also considered, especially when directly related to ammonite zones. There is no attempt to deal with the definition of the Jurassic–Cretaceous limit. Correlation of the V. mendozanum Zone with the Semiforme Zone is ratified, but it is open to question if its lower part should be correlated with the upper part of the Darwini Zone. The Pseudolissoceras zitteli Zone is characterized by an assemblage also recorded from Mexico, Cuba and the Betic Ranges of Spain, indicative of the Semiforme–Fallauxi standard zones. The Aulacosphinctes proximus Zone, which is correlated with the Ponti Standard Zone, appears to be closely related to the overlying Windhauseniceras internispinosum Zone, although its biostratigraphic status needs to be reconsidered. On the basis of ammonites, radiolarians and calpionellids the Windhauseniceras internispinosum Assemblage Zone is approximately equivalent to the Suarites bituberculatum Zone of Mexico, the Paralytohoplites caribbeanus Zone of Cuba and the Simplisphinctes/Microcanthum Zone of the Standard Zonation. The C. alternans Zone could be correlated with the uppermost Microcanthum and “Durangites” zones, although in west central Argentina it could be mostly restricted to levels equivalent to the “Durangites Zone”. The Substeueroceras koeneni Zone ranges into the Occitanica Zone, Subalpina and Privasensis subzones, the A. noduliferum Zone could be equivalent to the Dalmasi Subzone, Occitanica Zone, to lower part of the Boissieri Zone, and the S. damesi Zone could range through the upper part of the Boissieri Zone to the lower part of the Pertransiens Zone. Division of the Substeueroceras koeneni Zone and a precise correlation between the Andean ammonite zones and the international standard require new systematic and stratigraphic studies.

Opis:
Bay of Samsun is one of the most important oil transport gateways in Black Sea. The region is surrounded with the coasts which have various levels of environmental sensitivity. The purpose of this study is to investigate the oil spill and predict the future accidents likely to be encountered around the Bay of Samsun. To be well informed about fate, this study makes the best possible use of two trajectory models. One of them, ADIOS (Automated Data Inquiry for Oil Spills), has been applied to natural degradation calculations, and the other one, OILMAP (oil spill model and response system), has been used for surface spread simulation. Hence in order to identify the risky areas three scenarios have been developed. Their results reveal that in case of oil spills, with average environmental conditions, there is a risk of contamination for the city of Samsun. Although the area under the risk is the same, contamination density is totally different depending upon the quantity and the type of spilt oil. The results gained through these efforts are hoped to be useful for many organizations dealing with oil spill response operations and contribute to an effective coordination among the relevant institutions.

Opis:
In spite of the enormous achievements of medical and biological sciences, parasites still constitute important medical and veterinary problem. One of the main obstacles in the treatment and eradication of human and animals parasitic diseases is drug resistance of parasites. This phenomenon has more and more frequently been described both in medical and veterinary practice. The application of numerous molecular biology techniques in modern parasitological laboratories have enabled the investigations of parasites at the DNA level. The results of these studies have revolutionised our knowledge and made possible the recognition of not only the reasons and extent of genetic differentiation of parasites but also the recognition of genetic and molecular mechamisms of drug resistance. The results of many studies showed interspecific, interpopulational, and even intrapopulational heterogeneity of parasites in their sensitivity to antiparasitic drugs. Moreover, it has been found that in various parasites there often exist different molecular bases of the drug resistance. The review concerns different molecular mechanisms of drug resistance in selected parasite taxa (Schistosoma spp., Haemonchus contortus, Leishmania spp., Plasmodium falciparum, Entamoeba histolytica).

Opis:
Three isolated and well−preserved retiolitid taxa, two of them new, and one taxon of unknown affinity, are described from the upper Llandovery of Arctic Canada. All taxa display unusual characteristics The three retiolitids display extraordinary morphological features: Pseudoplegmatograptus cf. obesus preserves very delicate and lacey or cobweb−like list structures external to the main skeletal lists, structures previously seen only rarely on flattened material; Pileograptus pileatus gen. et sp. nov. possesses a thecal framework typical of retiolitines, particularly Stomatograptus, but its thecal orifices possess broad, meshwork genicular hoods similar to those in the plectograptines; and Giganteograptus giganteus, formerly attributed to Pseudoplegmatograptus, with its very coarse and relatively simple skeletal framework, well−developed paired thecal apertural spines, and a pustulose micro−ornamentation on the lists. The latter feature suggests an assignment to the subfamily Plectograptinae, rather than to the Retiolitinae as has been previously presumed. The presence of pustulose lists in Giganteograptus adds a further complication to understanding of retiolitid evolution. Mirorgraptus arcticus gen. et sp. nov., the fourth taxon and of unknown systematic affinity, lacks the proximal end, but preserves lists with seams and some fusellar material suggestive of some type of new retiolitid. Unlike known retiolitids or other graptolites, however, the skeletal list development is apparently confined to a narrow region along one side of the nema.

Opis:
The article comprises a critical review on practical applications of molecular technology in parasitological diagnostics in a broad sense, also as a diagnosis of species and a method of epidemiological analysis. Techniques of genome analysis at different levels, as specific nucleic acid probes, DNA restriction profiles (RFLP), hybridization techniques, pulse-field gel electrophoresis, in vitro nucleic acid amplification, and DNA fingerprint technique used in studies on Giardia and Cryptosporidium were discussed. The essential reservation as far as this technology is concerned refers to its usefulness in parasitological diagnostics; there is no sense in working out methods for recognizing parasites which could otherwise be identified by well trained parasitologists and simple microscopic methods. The improved diagnosis of parasites resulting from the application of molecular technology significantly contributed to the armentarium of parasitologists. Application of recent molecular technology in diagnosis of giardiosis and cryptosporidiosis may basically support clinical diagnosis which provides possibilities of early and selective treatment and makes possible epidemiological studies. These assays will permit not only a rapid diagnosis and exact differentiation but will also enable a better recognition of Giardia and Cryptosporidium genome organization. However, in spite of the wide availability of this new techniques they have not been fully applied - as yet – in diagnosis and in epidemiological studies on these parasites. The authors share the opinion of BUSCH (1991) on the need of proper recognition of high-quality and rigorous work in employing new molecular assays, because their wide availability and high sensitivity could cause "false-positive" results by contamination with amplified DNA sequences. They totally support the conclusion made by THOMPSON and MELONI (1993) that the molecular data must be fairly interpreted by collaborating molecular biologists, parasitologists, and epidemiologists - and clinicians as well - to avoid forming of a confusing picture of genetic diversity of the parasites with no practical application.

Opis:
A decomposition analysis of energy-related carbon dioxide emission intensities in Turkey from 1971 to 2010 has been presented. The refined Laspeyres method is used in the calculation to identify fossil fuel carbon effect, fossil fuel share effect and energy intensity effect that accelerate or reduce the increase in carbon dioxide emission intensities. The results show that the fossil fuel share effect and the energy intensity effect are the two biggest contributors to CO2 emission. The case analysis also shows that fossil fuel carbon effects play important roles in the decrease of CO2 emission intensities especially from 1988 to 2010.

Opis:
The present research has the objective of identifying the characterization and management of textile solid waste generated in clothing manufacturing within a local productive arrangement (LPA) in Brazil. The importance of this research consists in the data presentation and survey which indicate the scenario of textile solid waste, enabling the promotion of appropriate and sustainable management actions for these materials. Thus it is exploratory research with a qualitative and quantitative approach. After analysing the data, the main characteristics, dimensions and management practices of textile solid waste in these industries are presented. The research results point out a considerable amount of textile solid waste that is generated and appropriate practices for the management of such waste. Nevertheless there is a need for improvement of this process aiming at enhancement opportunities of the materials mentioned as raw material in the development of the same products or other segments, in order to promote sustainable action.

Opis:
The stationary acoustic field in a two pIane parallel medium, sea surface and sea boftom, when a source near to the sea surface radiates, is characterized by the thickness of the medium and the reflectivity of the boundary surfaces. It is known that the maxima and minima of pressure are produced at same given depths depending on the radiated frequency and distance. Considering the ship noise as an acoustical source, the frequency spectrum of the acoustic pressure at certain depth, is nof only the spectrum of the acoustic ship noise but it is also modified by the wave field originated by consecutive reflections at the boundary surfaces. As a consequence, over the free field spectrum of (he ship noise, a series of minima appears. The corresponding frequencies are those for which the receiver is located at the nodes of the stationary wave field.

Opis:
The authors present the actual review on several publications concerning the molecular characterizations of the viruses found in parasitic protozoa such as Giardia, Trichomonas, Leishmania and Entamoeba histolytica. All of the RNA viruses observed in parasitic protozoa showed several similarities and did not considerably differ from the viruses found in simple eukaryotic cells; they closely correspond to dsRNA viruses of yeast. The supposition that the protozoan symbionts detected in laboratories transfer to their hosts in natural conditions seemed to be rational, though, there are no evidences that these symbionts are potential pathogens. However, the opinion reiterates that intestinal protozoa (e.g. Entamoeba histolytica) may serve as vectors for HIV or cofactors of HIV infection. The authors point out that irrespective of the potential role of viruses as vectors in the transfection system for parasitic protozoa, the observed viral system constitutes an unusual experimental system to solve the problems of gene expression.

Opis:
The article comprises a critical review on practical applications of molecular technology in parasitological diagnostics in a broad sense, also as a diagnosis of species and a method of epidemiological analysis. Techniques of genome analysis at different levels, as specific nucleic acid probes, DNA restriction profiles (RFLP), hybridization techniques, pulse-field gel electrophoresis, in vitro nucleic acid amplification, and DNA fingerprint technique used in studies on Giardia and Cryptosporidium were discussed. The essential reservation as far as this technology is concerned refers to its usefulness in parasitological diagnostics; there is no sense in working out methods for recognizing parasites which could otherwise be identified by well trained parasitologists and simple microscopic methods. The improved diagnosis of parasites resulting from the application of molecular technology significantly contributed to the armentarium of parasitologists. Application of recent molecular technology in diagnosis of giardiosis and cryptosporidiosis may basically support clinical diagnosis which provides possibilities of early and selective treatment and makes possible epidemiological studies. These assays will permit not only a rapid diagnosis and exact differentiation but will also enable a better recognition of Giardia and Cryptosporidium genome organization. However, in spite of the wide availability of this new techniques they have not been fully applied - as yet – in diagnosis and in epidemiological studies on these parasites. The authors share the opinion of BUSCH (1991) on the need of proper recognition of high-quality and rigorous work in employing new molecular assays, because their wide availability and high sensitivity could cause "false-positive" results by contamination with amplified DNA sequences. They totally support the conclusion made by THOMPSON and MELONI (1993) that the molecular data must be fairly interpreted by collaborating molecular biologists, parasitologists, and epidemiologists - and clinicians as well - to avoid forming of a confusing picture of genetic diversity of the parasites with no practical application.

Opis:
Prześledzono zależności pomiędzy zróżnicowanym nawożeniem NPK, zawartością azotanów(V) w bulwach ziemniaka a nasileniem występowania zarazy Phythophthora infestans na plantacji ziemniaka. Rozwój zarazy na roślinach w okresie wegetacji zależał od warunków klimatycznych i dawki nawożenia mineralnego. Najwyższe indeksy porażenia wystąpiły na odmianie Rywal przy dawce 160 kg N·ha⁻¹ (Ip = 63,6%) w zimnym i mokrym roku 2004. Najniższe porażenie patogenem zanotowano w 2003 roku na odmianie Tokaj nawożonej dawką 40 kg N·ha⁻¹ (Ip = 22,6%). Analizy bulw na zawartość NO₃⁻ wykazały ścisłą zależność ilości azotanów(V) od wzrastającej dawki nawożenia mineralnego. Bezpiecznym poziomem nawożenia NPK, przy którym nie stwierdzono przekroczenia dopuszczalnej normy 200 mg NO₃⁻·kg⁻¹ świeżej masy bulw, była dawka N₄₀P₁₇K₅₀. Wyższe dawki NPK sprzyjały nagromadzaniu NO₃⁻, szczególnie przez odmianę Tokaj. Stwierdzono istotny związek pomiędzy stopniem porażenia roślin w czasie wegetacji i zawartością NO₃⁻ w bulwach po zbiorze. Większą zawartością azota- nów(V) charakteryzowały się bulwy spod roślin w mniejszym stopniu porażanych przez Phytophthora infestans.
The aim of the presented study was to state the dependencies between different NPK fertilization, tuber nitrate content, and potato plant infestation by Phythophthora infestans during growing season. The development of infection depended on weather conditions and amount of mineral fertilizers. The highest infestation index (Ip = 63.6) was noted for Rywal cultivar fertilized with 160 kg N·ha⁻¹ in 2003 with cold and wet weather. The lowest infestation was noted in the year 2003 (Ip = 22.6%) for cultivar Tokaj fertilized with 40 kg N·ha⁻¹. The nitrates content in analyzed tuber samples depended on the elevated rates of NPK fertilization. The maximum level of nitrates for human consumption is 200 mg NO₃⁻·kg⁻¹ of fresh mass. During the presented study it was stated that only N₄₀P₁₇K₅₀ was acceptable for safe level of tuber nitrates. The higher rates of NPK caused a higher nitrates level especially in the cultivar Tokaj. A significant relation between the degree of plant infestation during vegetation and the NO₃⁻ content in tubers after harvest was observed. A higher NO₃⁻ amount noted in tubers derived from plants of a higher infected by pathogen Phythophthora infestans.

Opis:
Computers are used in the outdoors and in connection with cold store work. Cold hand and fingers limit data input, as studied here. Six input devices; trackballs, pens, and a mouse were tested by 19 participants in a Fitts' target acquisition task with 2 target sizes under 2 experimental conditions; warm and cold right hand. Measures were acquisition times, number of errors, participant's preferences, and observed handling of the devices. Effects of device, target size, and cold were significant. Learning and attempts to improve handgrip were confirmed. Large enough targets, a thick pen, and a mouse make computer work practicable in the cold. Direct visual feedback, as with pen on template with target images, shortened acquisition times by half a second.

Opis:
This note points out that a utility maximization procedure proposed in an earlier paper may be reduced to the least squares. The utility function is asymmetric in the sense that for each cue its ideal value and the permissible range are assigned in such a way that the ideal is not necessarily at the center of the range, like "a beer of 350 ml would be ideal, but acceptable if within [100, 500]". A practical consequence of the observation is that very little programming will be needed to deploy the utility maximization since software for the least squares is widely available.
