Definite Correlation

The Gezira Scheme is divided into three areas according to the incidence of the Cotton Jassid, Empoasca lybica.1. The Northern area of normal abundance.2. The Central area of occasional abundance.3. The Southern area of possible abundance.The causes for this difference in the number of Jassids in the three areas were studied and rainfall in showers over 10 mm. in July and August was found to be the important factor. A definite correlation was found between the number of Jassids on cotton and the amount of this rainfall.Some experiments were carried out which proved that the effect of rain was due to the splashing of mud from the soil on to the lower side of the leaves. The rain could therefore be effective if it is heavy enough to produce mud splashing.It was shown by a simple apparatus that mud splashing hardly rises more than 30–40 mm.The correlation between the number of Jassids and the amount of rainfall in July and August might be used as a basis for forecasting the extent of Jassid attack on cotton every year.

Maya history can be divided into four great periods; the formative, the initial series, the Mexican, and the Mexican absorption. The formative period (prior to A.D. 300) comprises the Mamom and Chicanel phases at Uaxactun and coeval phases found elsewhere in the central area (Petén, British Honduras, Chiapas, Tabasco, lower Motagua, drainage), the northern area (Yucatan, northern Campeche, Quintana Roo) and, as we shall see, the southern area.

Norm Scores

Background: The Fibromyalgia Impact Questionnaire (FIQ) is the most used questionnaire worldwide to measure the health status of patients with fibromyalgia. The questionnaire has been subjected to several studies to analyze psychometric properties. However, norm scores and cultural differences have not been presented. Objectives: To obtain and present norm scores for the FIQ in patients with fibromyalgia in different cultures, namely Southern, Central, and Northern areas of Europe. Study Design: This observational study consisted of women with fibromyalgia from 4 countries (Spain, Belgium, the Netherlands, and Sweden) classified in 3 areas (Southern, Central, and Northern) in Europe. Setting: Women with fibromyalgia from Spain, Belgium, the Netherlands, and Sweden. Methods: The impact of fibromyalgia was assessed by the FIQ. A total of 1,478 women with fibromyalgia were asked to fill out the FIQ in the Spanish (n = 531), Dutch and Belgian (n = 629), or Swedish (n = 318) versions. Results: The norm scores and percentiles score of the FIQ are presented. Norm scores differed between European areas (Southern area = 64.8 ± 15.9; Central area = 60.9 ± 15.7; Northern area = 62.8 ± 16.7). Perceived physical impairment, overall well-being (all, P < 0.001), FIQ total (P < 0.01), and morning tiredness (P < 0.05) in women with fibromyalgia from the Central area of Europe reported lower impact than Southern and Northern areas. The Northern area of Europe showed the lowest score of job difficulty, anxiety, depression (all, P < 0.001), and pain (P < 0.01), whereas the Southern area of Europe showed the lowest score of work missed subscale (P < 0.001) with regard to the rest of the areas studied. Limitations: The selection of patients was conducted with just women because of the scarce prevalence of fibromyalgia among men. Moreover, sociodemographic status, socioeconomic status, and clinical characteristics were not measured. Similar research should be conducted with adequate representation of populations from other parts of the world. Conclusions: Pairwise comparisons showed significant differences mainly between the Southern area versus Northern and Central areas of Europe. The impact of fibromyalgia showed mainly higher scores in women with fibromyalgia from the Southern area of Europe. Key words: Symptom, psychometric, norm scores, European comparison

The subject of research is the anthroponymy of the Ruthenian (Ukrainian) population living in the historical territories of the eastern Lublin region on the Polish-East-Slavic borderland. The underlying objective of the study was to investigate the Ruthenian onomastics functioning in the historical Polish-Ukrainian onomastics and to highlight the territorial diversification of the personal names of Ukrainians, related to the dialectal diversity in the studied territory. The reference database is personal proper names excerpted from the parish registers of Uniate parishes in the former Chełm diocese. The territory investigated was divided into three areas: northern, central and southern, based on the ranges of the Ukrainian dialects spoken in the territory of present-day Poland. The research material was excerpted from the records of Uniate parishes in the former Chełm diocese in the years of 1662–1810. The northern area, defined by the range of Podlasie local dialects, and the central area, determined by the ranges of transitional dialects from northern to southern ones and Volhynian dialects, exhibit features closely similar to peasant anthroponymy, while the southern area, defined by the ranges of Dniester and San dialects, presents features characteristic of the anthroponymy of the lower Ukrainian gentry.

Abstract Parasite composition can be affected by physiological and ecological changes during host ontogeny. Intertidal fish do not travel long distances and live in the same area throughout their lifetimes, meaning that parasite communities can differ across geographic ranges. The objective of this study was to analyse the parasite communities of three fish species (Hypsoblennius sordidus, Helcogrammoides cunninghami and Scartichthys viridis) collected from the Chilean coast. The composition of parasite species was compared among host ontogenetic stages (larvae, juveniles and mature fish) and geographic areas. A total of 184 larval, 252 juveniles and 217 mature individuals were collected in the northern area (c. 24°S), and 186 larval, 192 juveniles and 112 mature individuals from the central area (c. 33°S). Ectoparasites were most prevalent in fish from the central area, whereas endoparasites were most prevalent in the northern area. The parasite species richness varied significantly between geographical areas for H. sordidus and H. cunninghami, but the parasite composition varied significantly between geographical areas for all fish species analysed. Therefore, the geographical area was the most important factor determining the parasite composition of intertidal fish species. The absence of endoparasites in fish larvae and the increased infestation in juvenile and mature fish may be explained by the shift in habitat from the water column to intertidal pools where prey abundance and availability are higher. On the other hand, hydrographic barriers affecting prey distributions may also offer an explanation as to the differences in parasite composition.

Data for 12 crops, 1927 to 1938, have been used to examine the protein contents of Grades 1, 2, and 3 Northern drawn from the northern and north-western area, and from the central and southern area, of Western Canada. The boundary between the areas was taken as that dividing zones averaging over and under 13% protein. Grades 1, 2, and 3 Northern from the southern area averaged 14.2, 14.0, and 14.0% protein; those from the northern area averaged 12.8, 12.0, and 11.6% protein; and the average difference between zones for all three grades was 2.0%. The reasons for the increase in the spread between zones with decreasing grade are discussed. For the 12 yr. period, the average protein content of shipments of Western Canadian wheat is estimated as 13.5%. If no wheat had been shipped from the northern zone the average protein level would have been increased by about 0.5 per cent.

PURPOSE In this study, we aimed to investigate trends in the age-standardized and age-specific incidence rates in two distinct regions (the northern and southern areas) of South Africa covered by a population-based cancer registry. In addition, trends in coverage of the cervical cancer screening program were assessed using routine health service data. METHODS Occurrences (topography C53.0-C53.9) for the period 1998-2012 were extracted from a cancer registry database from which basic descriptive statistics and frequencies were analyzed for all variables using CanReg4. Trends over time were estimated using a direct standardization method and world standard population as a reference. Screening coverage annualized figures for women age ≥ 30 years by sub–health district were extracted from the District Health Information System. RESULTS In the northern area, annual age-standardized incidence rates per 100,000 women increased from 24.0 (95% CI, 21.1 to 27.0) in 1998-2002 to 39.0 (95% CI, 35.6 to 42.5) in 2008-2012, with a screening coverage rate of 15% by 2012. In contrast, no increase was observed in incidence in the southern area, with rates of 20.0 (95% CI, 18.5 to 21.4) in 1998-2002 and 18.8 (95% CI, 16.2 to 21.4) in 2008-2012, and the southern area had a higher screening coverage of 41% in 2012. Overall, the percentage distribution of stage at diagnosis showed that 28.5% of occurrences were diagnosed at disease stages I and II and 35%, at III and IV; 36% had with missing stage information (2003-2012). In 77% of occurrences, a histologically verified diagnosis was made, compared with only 12.3% by cytology. CONCLUSION This study has demonstrated an almost two-fold increase in the incidence rate in the northern area but little change in the southern area of the cancer registry.

AbstractThe Claymore Field is located in UK North Sea Block 14/19 on the southwest margin of the Witch Ground Graben. The principal structure is a southerly tilted and truncated fault block. The field is divided into three producing areas. Major production is from Upper Jurassic paralic sandstones of the Sgiath Formation and turbidite sandstones of the Claymore Sandstone Member of the Kimmeridge Clay Formation in the downflank Main Area. Minor production is from Permian carbonates of the Halibut Bank Formation and Carboniferous sandstones of the Forth Formation in the crestal Central Area. The Northern Area is a northerly plunging nose, extending graben wards from the Claymore tilt block. Production in the Northern Area is from Lower Cretaceous turbidite sandstones of the Valhall Formation.A small amount of oil was recovered on a wireline test in 1972 from Permian carbonates in the crestally located 14/19-1 well, in what is now termed the Central Area. In 1974 the Main Area was discovered by the southerly downdip well 14/19-2, and the Northern Area was discovered by the northerly downdip well 14/19-6A. Initial oil in place was 1452.9 MMBBL with currently estimated ultimate proved recovery of 511.0 MMBBL of oil. A 36-slot steel platform was installed in 1977. Two subsea water-injection templates were added in 1981 and 1985. Cumulative production to 6 July 1988 was 322.9 MMBBL of oil and daily production was 75 000 BOPD of oil from 28 producers, supported by 16 injectors.

Niuean (ISO 639-3 code niu) is a Polynesian language spoken on the island of Niue, with an additional population of speakers living in New Zealand. Figure 1 indicates where Niue is located with respect to other neighboring islands in the South Pacific. The 2011 Niue Census of Populations and Households cited the number of individuals who had either basic or fluent spoken abilities at 1121 (with 101 non-speakers) (Statistics Niue 2012). English is the second most widely used language on the island. The 2013 New Zealand census cited 4548 individuals living in New Zealand who listed Niuean as one of their languages (Statistics New Zealand 2013). Niuean is classified as ‘definitely endangered’ by UNESCO (Moseley 2010). There are historically two distinct dialects: the older Motu dialect from the northern area, and the more recent Tafiti from the southern area. These dialect differences were once reflected in slight phonological differences in vocabulary items, but the differences have since eroded in the modern language (see McEwen 1970: ix). Previous research on Niuean phonetics and phonology includes a brief outline in Seiter (1980: x), two dictionaries (McEwen 1970, Sperlich 1997), and an article on vowel length (Rolle & Starks 2014). While these works provide an overview of some of the phenomena to be addressed below, this sketch attempts a more thorough documentation of the phonetic structures of Niuean, and provides novel acoustic and articulatory data from the language. Recordings accompanying this paper are of a male speaker (Mr. Krypton Okesene) and a female speaker (the second author).

In Quebec, the Aroostook–Percé Anticlinorium exposes two stratigraphic groups: the Honorat and the Matapédia. The terrigenous units of the Honorat Group form the core of the anticlinorium and are overlain by the carbonate sequence of the Matapédia Group. Each group comprises two formations. The Honorat is herein divided into two new formations, the Arsenault and the Garin, which are defined for the first time. The Matapédia Group includes the Pabos and White Head formations. The Pabos Formation, a transitional unit between the noncalcareous strata of the Honorat Group and the carbonate facies of the White Head Formation, is here redefined. The White Head Formation comprises four members. These two groups represent continuous sedimentation from the Late Ordovician (Caradocian) to the Early Silurian (Llandoverian).The lithostratigraphy of the type areas of the Honorat Group (Honorat Township region) and Pabos Formation (Chandler region) are fully described, whereas the lithostratigraphy of the type area of the White Head Formation (Percé area) is summarized only. The Arsenault, Garin, and Pabos formations and the Burmingham, Côte de la Surprise, L'Irlande, and Des Jean members of the White Head Formation constitute the stratigraphic sequence in the eastern part of the Aroostook–Percé Anticlinorium. These units are extended to the western part of the anticlinorium in Quebec and in New Brunswick, and also to other Late Ordovician – Early Silurian rocks in the Chaleur Bay and Gaspé – Connecticut Valley synclinoria.Rocks of the Aroostook–Percé Anticlinorium are interpreted as having been deposited by turbidity currents in a relatively deep water basin. Deposition evolved through time from terrigenous to limestone, reflecting a change in source areas.The Grand Pabos fault divides the Aroostook–Percé Anticlinorium between Percé and Carleton into two areas with stratigraphically different sequences. The northern area is dominated by carbonate rocks of the Matapédia Group, whereas the southern area is composed mainly of terrigenous facies of the Honorat Group. Carbonate sedimentation of the White Head Formation started during Late Ordovician time in the northern area but only during Early Silurian times in the southern area. The thickness of the carbonate strata, which reaches 2000 m in the northern area, diminishes to 150 m in the southern area.

The influence of terrestrial and marine input has dramatically changed eutrophication in coastal seas over the past 100 years. In this study, Zhoushan coastal sea (ZCS) is taken as a study area. We studied ZCS as it is a sink of the temporal and spatial variation of primary productivity, dominant species of algae, and the variation of provenance in this area over the past 100 years. We performed analysis using three sediment cores and the carbon and silicon deposition records. The analysis results demonstrate that: (1) The primary productivity in the northern area of the ZCS close to the Yangtze Estuary was the highest comparatively, but it declined slightly before 2010. The primary productivity in the southern area had an increasing trend over the past 100 years. The value of total organic carbon (TOC) in the northern area was relatively high, with an average value of 0.532% over the past 100 years, with a decreasing trend in recent years. On the contrary, TOC in the southern area was relatively low, but it was increased dramatically after 1995. (2) Diatom might play an important role in the variations. The biogenic silica (BSi) and TOC in the northern area showed a synchronous declining trend, while the BSi/TOC ratio did not change significantly. This indicates the algae population structure in this area was relatively stable over the past 100 years. The BSi/TOC ratio decreased continuously in the southern area, indicating that the dominance of diatoms was decreasing continuously. (3) The variation of diatom dominance in this area might have a great relationship with the change of nutrients’ provenance. A mean value of stable carbon isotope (δ13C) in the north of Zhoushan was −23.46‰, indicating that the terrestrial-source input was the highest. (4) The change of provenance in the study area was quite different. This illustrates that the terrestrial input impacted the largest area of ZCS while marine input became dominant in the offshore area.
