Opis:
Rivers have always been in great importance in the process of arising and developing the human civilisation. Many ancient cultures were very powerful because of the huge rivers systems. Such civilizations as Egypt, Mesopotamia, India and China came into being in the grand rivers valleys (Nil, Tiger, Euphrates, Indus, Ganges, Yangtze and Huang He). Nowadays those rivers also play the vital role because of the fact that of its state and affluence mainly depends the economic stability and in that connection depends also the politic stability in the countries that those rivers flow through. Those dependences and connections between people and rivers were best characterised by the Greek historian Herodotus in his saying "Egypt is a gift from the Nile". Contemporary domestic and international rules of using the rivers resources are regulated by the law rules. The international law rules mainly deal with law classification and the division of the international rivers, water transport on those rivers and the methods of making out the rivers boundaries. Determining the international law rules, effectively regulating the exploitation of the international rivers, face many obstacles. The reason of this situation are differences in exploiting the rivers resources in particular States, which depends on many aspects (economic, geographical, cultural, etc.). The very best example of the complexity of the international rivers systems matter is the Nile river. Present-da y, for the Nile's drainage basin states, establishing the new international law regulations and the arrangements concluding the rational exploitation and division of the rivers resources is the main problem. In the light of the II article of the 1966 Helsinki Rules on the Uses of the Waters of International Rivers, an international drainage basin is a geographical area extending over two or more States determined by the watershed limits of the system of waters, including surface and underground waters, flowing into a common terminus. According to this criterion, ten States count among drainage basin of the Nile river (those States are as follows: Egypt, Sudan, Ethiopia, Eritrea, Burundi, Ruanda, Kenya, Uganda, Tanzania and the Democratic Republic of Congo. Those States are now developing and theirs weak national economies are based on agriculture. The Nile as one of the biggest and most resourceful river on the world, is a great opportunity for those countries to develop. Unfortunately, present international legal system does not allow to exploit the Nile’s water resources in optimal and fair way, because this system does not embrace most of the States of the drainage basin. Such situation cause conflicts and tensions in relations between those States.

Opis:
This study was initiated to achieve the specific objectives as identification of factors that affect market participation decision of households and identification of factors that determine the volume of market supply of pepper. In order to acquire the relevant data, formal and informal methods of data collection were accomplished. To differentiate factors affecting the market participation and the amount of pepper sold, the Heckman Two-Stage econometric model was employed. The result revealed that market participation decision of households and amount of pepper sold were significantly affected by many of the variables hypothesized to have impact on the explained variable. In order to settle price fluctuations and to strengthen the bargaining power of producers, there should be product grading for market standardization. Furthermore, market competitiveness, structure and efficiency can be improved through facilitating pepper market strategies training as it helps producers and other interested bodies better involve in the commodity market.
Celem pracy było rozpoznanie czynników determinujących udział w handlu oraz podejmowanie przez właścicieli gospodarstw rolnych decyzji dotyczących wysokości produkcji papryki dostarczanej na rynek. Zastosowano zarówno formalne, jak i nieformalne metody pozyskiwania odpowiednich danych. Dwustopniowy ekonometryczny model Heckmana zastosowany w tej pracy zakładał zróżnicowanie i określenie czynników mających wpływ na decyzję o udziale w handlu rynkowym i wysokość oferty rynkowej. Otrzymane wyniki wykazały, że na omawiane decyzje, odnoszące się do wyjaśnianej zmiennej, znaczący wpływ miały hipotetycznie zakładane zmienne. Stwierdzono konieczność jakościowego określenia produktu dla celów standaryzacji rynkowej po to, ażeby ustalić fluktuacje cen i wzmocnić moc przetargową producentów. Należy dodać, że konkurencyjność rynkową, strukturę i wydajność można poprawić poprzez zapewnienie producentom i innym zainteresowanym szkoleń z zakresu handlu papryką, co służyłoby znaczniejszemu zaangażowaniu na rynku produktów rolnych.

Opis:
Thirty-four identified in addition to five unidentified species appertaining to ten genera of zoosporic fungi were identified and isolated from eighty four polluted water samples, which were randomly collected from different polluted sites of the water drainages along the Niles Delta in Lower Egypt. Baiting sesame seeds culture technique was employed at 20±2°C for the recovery of zoosporic fungi. The genera; Pythium and Saprolegnia (8 and 7 zoosporic fungal species, respectively) showed the broadest spectra of species diversity whereas Aqualinderella was only represented by one species (A. fermentans). Saprolegnia delica and Dictyuchus carpophorus(the greatest fungal populations) were the most dominant isolated zoosporic fungal species where they were highly occurred especially at the hyperpolluted waters with the heavy metals. These two species could be considered as indicators for the response of the structure and function of microbial communities for water pollution. Several zoosporic fungal species were rarely encountered. Both Aqualinderella fermentansand Pythium rostratumwere recovered in moderate frequency of occurrence. Water samples which had high concentrations in heavy metals were the poorest in the species diversity of zoosporic fungi. Despite that, fungal species belonging to the family Saprolegniaceaeflourished in hyper polluted water samples whilst those belonging to the family Pythiaceae predominated in more diluted water samples. Also, the prevalent species; S. delica andD. carpophoruswere not affected by heavy metals concentrations being as indicators for water pollution with the heavy metals. pH values of the polluted water samples had no influence on the occurrence of zoosporic fungi. Water samples characterized by high organic matter content and low total soluble salts were the richest in zoosporic fungal species.

Opis:
The purpose of this investigation was to compare Rapid Hicoliform Agar® (RHA, Himedia, India) with the conventional m-Endo Agar (DIFCO, Michigan, USA) for detection and enumeration of Total Coliforms (TC) and with the conventional Seven Hour Fecal Coliforms Agar (7hFC) for detection and enumeration of Escherichia coli using Membrane Filtration (MF) in River Nile water, Egypt. Sixty samples were collected (five samples per month) from five regions (Kafr El-Elw, El-Maasara, El-Giza, Embaba and El-Galatma) during one year (December 2005-November 2006). The results showed that total coliforms counts ranged from 103 to 104 CFU*100ml-1 using RHA but using m-Endo Agar the counts were around 104 CFU*100ml-1. Escherichia coli counts ranged from 103 to 104 CFU*100ml-1 using 7hFC Agar, while using RHA the counts ranged from 103 to 104 CFU*100ml-1. Statistical analysis showed that there was no significant difference (p=0.423) between total coliforms counts using m-Endo Agar and RHA media, also, there was no significant difference (p=0.546) between fecal coliforms (E. coli) counts using 7hFC Agar and RHA media. We conclude that RHA is a potential alternative medium for detection and enumeration of total coliforms and E. coli at the same time and the same Petri dish within 24h. Also, RHA medium was a very sensitive medium, which did not require any confirmatory tests and secured rapid recovery of total coliforms or E. coli.

Opis:
The river Nile is a dominating physical feature of the north- eastern part of the African continent, covering areas exhibiting varieties and contrasts in topography, climate vegetation and people. So, in this study, we estimated the contamination of the Nile sediment with some major and trace heavy metals in core samples which can cause some undesirable health effects. Concentrations of all elements shows that the maximum enrichment is found in the top subsamples, while the most elements shows low contents in the lower layer reflecting the impact of human activity on the sediment contents. Different normalizing methods were used, i.e. geoaccumulation (Igeo) and enrichment factor (EF), for the influence of the natural variability in sediment mineralogy and to assess whether the concentrations observed in surface sediment represent background or contaminated levels. The study has also shown the importance of different sediment characteristics in spatial distribution of heavy metals in the sediments of river Nile. To protect the ecological system of river Nile watershed, industrial mining and agricultural activities along river stream should to be strictly regulated.

Opis:
In the climate change context, controlling water sources is one of the most explosive challenges to the stability of the security environment. In its quasitotality, human civilization was born in the basins of the great rivers, which provided humans with both the basic survival and development resources and natural protection against invasions. Such a watercourse is the Nile, in whose basin the great Egyptian, Nubian and Ethiopian civilizations were born. If, until recently, Egypt was the main beneficiary of the Nile's ”gifts“, Grand Ethiopian Renaissance Dam (GERD) project, still in construction on the Blue Nile, will radically change the status quo in region. How will GERD going to influence the regional hydro-policy? Is there any risk for a regional war outbreak? And, if the answer to the previous question is a positive one, what could be the impact of an Egyptian-Ethiopian conflict on regional security?

Opis:
The Nile River is the main route for inland navigation in Egypt. The vessels navigating through inland waterways generate complex physical forces that need to be studied extensively. Quantifying the effects of vessels sailing along a waterway is a complex problem because the river flow is unsteady and the river bathymetry is irregular. This paper aims to investigate the hydrodynamic effects resulting from the movement of vessels such as return currents around the vessel, the draw down of the water surface, under keel clearance, and the shear stress induced by vessels operating in the Nile River. Modeling such effects has been performed by applied the two-dimensional ADH (adaptive hydraulics) model to a river reach for different navigation channel operation scenarios. The obtained results show that the draw down heights, the water fluctuation, and the shear stress magnitude are larger when the river cross sectionals are narrow and the shallow water depths. These river sections are considered more disposed to bed erosion and it is morphologically unsafe. The section having the narrowest width and the lowest depth was associated with the largest drawdown percentages of 98.3% and 87.3% in one-way and two-way scenarios. While the section having the widest width and the largest depth was associated with the least drawdown percentages of 48.5% and 51.9% in one-way and two-way scenarios. The section having the narrowest width and the lowest depth was associated with the largest fluctuations of 22.0 cm and 41.9 cm in one-way and two-way scenarios. While the section having the widest width and the largest depth was associated with the least fluctuations of 0.6 cm and 1.8 cm in one-way and two-way scenarios. The section having the narrowest width and the lowest depth was the worst section for under keel clearance of 5.0 cm and 33.3 cm in one-way and two-way scenarios. While the section having the widest width and the largest depth was the best section, where its clearance values were 183.2 cm and 155.0 cm in one-way and two-way scenarios. It is concluded that a numerical model is a valuable tool for predicting and quantifying the hydrodynamic effects of vessels moving through a two-dimensional flow field and can be used to evaluate different scenarios that are difficult to measure in the field or a physical model. Also, it provides visualization products that help us understand the complicated forces produced by vessels moving in a navigation channel.

Grecki przymiotnik ποταμοφόρητος występuje w Piśmie Świętym tylko raz – w Ap 12, 15. Polski przekład Biblii Tysiąclecia zdanie celowe, w którym ποταμοφόρητος występuje, oddaje jako: „żeby ją rzeka poniosła”. G. Schneider, autor hasła ποταμοφόρητος w Exegetisches Wörterbuch zum Neuen Testament, proponuje korektę znaczenia tego słowa, koncentrując się na domniemanym celu porwania przez wodę, czyli spowodowaniu zatonięcia. Aby rozstrzygnąć zaistniały problem, podejmujemy w pierwszej kolejności studium etymologii terminu ποταμοφόρητος (pochodzi od rzeczownika ποταμός – „rzeka” i utworzonego od czasownika φορέω przymiotnika φορητός – „niesiony, dający się unieść”) oraz przegląd kompositów z przymiotnikiem φορητός (nie zawierały one idei śmiertelnego zagrożenia). Do przełomu XIX i XX wieku ποταμοφόρητος był poświadczony poza Biblią tylko w pochodzącym z przełomu V i VI wieku leksykonie Hezychiusza, który mógłby stanowić uzasadnienie propozycji G. Schneidera. Odkryte i opracowane na przełomie XIX i XX wieku papirusy egipskie, w których ποταμοφόρητος jest odnoszone do wylewów Nilu, pozwalają tę propozycję poddać w wątpliwość, lecz problemu nie rozstrzygają. Następne pole poszukiwań stanowią starożytne przekłady Apokalipsy (VL, Wg, syryjskie i koptyjskie), dostarczające poparcia to jednej, to drugiej możliwości, oraz łacińskie i greckie komentarze patrystyczne, w których uzasadnienie znajduje dotychczasowy polski przekład. Komentatorzy rzekę mającą porwać Niewiastę rozumieją jako obraz prześladowań Kościoła i chęć ich prowodyra, by Kościół sobie podporządkować. Jedna z wersji przekładu VL (typ I) zwraca poszukiwania w kierunku pierwowzoru, jakim była prawdopodobnie rzeka Nil. W świetle starożytnych opinii na temat przyczyn wylewów Nilu (wiatr od strony Morza Śródziemnego miał powodować, iż Nil zaczynał płynąć w górę swego biegu) oraz czytelnej wówczas paraleli Ez 29, 3. 6 można przypuszczać, że to właśnie ta rzeka była modelem dla autora Apokalipsy. Dane te na tle starożytnych przekładów i komentarzy pozwalają na potwierdzenie słuszności dotychczasowego polskiego tłumaczenia słowa ποταμοφόρητος.
The paper presents a study on translations of a Greek word ποταμοφόρητος occurring in Rev 12 : 15. The Greek hapax legomenon ποταμοφόρητος is used in Rev 12 : 15. The part of the sentence containing ποταμοφόρητος is translated as: to sweep her away with the current. G. Schneider suggests a correction of the meaning of the word, concentrating on the conjectural purpose of being taken by water (drowning). In order to analyse this issue we begin with the study of etymology of the ποταμοφόρητος. It comes from the noun ποταμός and the adjective φορητός, which is a derivative of φορέω. Composita (compounds) formed with φορητός did not refer to any idea of a mortal threat. Till the turn of 19th century ποταμοφόρητος, apart from the Bible, was only certified in the Hesychius’ Lexicon (5th or 6th century). The Egyptian papyri, uncovered and analysed on the turn of the 19th and the 20th century, in which the ποταμοφόρητος is related to the overflows of the Nile, let us doubt Schneider’s proposal, however, still do not solve the problem. The next stage of the research consisted of the analysis of the classical and antique translations of Rev (VL, Vg, Syriac and Coptic translations), as well as Latin and Greek patristic commentaries, which support one of the aforementioned interpretations. The commentators understood the river carrying the Woman as the image of Church persecution and a desire to place the Church under the command of evil forces. One of the versions of the translation of Vetus Latina (type I) suggests that the archetype of the water torrent in Rev was the Nile. In the light of classical explanations as to the reasons of the river’s floodings, as well as the parallel in Ezek 29 : 3. 6 we can assume that it was the Nile that served as the archetype of the spewing torrent for the author of the Revelation.
