Many pathologies can occur in the periportal space and manifest as fluid accumulation, visible in Computed tomography (CT) images as a circumferential region of low attenuation around the intrahepatic portal vessels, called periportal halo (PPH). This finding is associated with different types of hepatic and extra-hepatic disease in humans and remains a non-specific sign of unknown significance in veterinary literature. The aim of this study was to investigate the prevalence of PPH in a population of patients undergoing CT examination and to assess the presence of lesions related to hepatic and extra-hepatic disease in presence of PPH. CT studies including the cranial abdomen of dogs and cats performed over a 5-year period were retrospectively reviewed. The prevalence of PPH was 15% in dogs and 1% in cats. 143 animals were included and the halo was classified as mild, moderate and severe, respectively in 51%, 34% and 15% of animals. The halo distribution was generalized in 79 cases, localized along the second generation of portal branches in 63, and along the first generation only in one. Hepatic disease was present in 58/143 and extra-hepatic disease in 110/143 of the cases. Main cause of hepatic (36%) and extra-hepatic disease (68%) was neoplasia. Associations between halo grades and neoplasia revealed to be not statistically significant (p = 0.057). In 7% of animals the CT examination was otherwise unremarkable. PPH is a non-specific finding, occurring in presence of a variety of diseases in the examined patient population.

We need an alternative model to education that will turn students on to learning. Such a model must recognize the ability each student brings to the learning experience. At the Learning Center for Anthropology at Santa Fe Community College in Gainesville, Florida, a smorgasbord of experiences using different types of media was substituted for the traditional academic menu. Early studies show several definite trends for the multimedia classroom: increased student-teacher contact; increased performance by students who are first generation college participants; decreased course costs per student-hour; and greater individualization of instruction.

Soil Erosion By Water

Soil erosion by water is affected by the rainfall erosivity, which controls the initial detachment and mobilization of soil particles. Rainfall erosivity is expressed through the rainfall intensity (I) and the rainfall kinetic energy (KE). KE–I relationships are an important tool for rainfall erosivity estimation, when direct measurement of KE is not possible. However, the rainfall erosivity estimation varies depending on the chosen KE–I relationship, as the development of KE–I relationships is affected by the measurement method, geographical rainfall patterns and data handling. This study investigated how the development of KE–I relationships and rainfall erosivity estimation is affected by the use of different disdrometer types. Rainfall data were collected in 1-min intervals from six optical disdrometers at three measurement sites in Austria, one site in Czech Republic and one site in New Zealand. The disdrometers included two disdrometers of each of the following types: the PWS100 Present Weather Sensor from Campbell Scientific, the Laser Precipitation Monitor from Thies Clima and the first generation Parsivel from OTT Hydromet. The fit of KE–I relationships from the literature varied among disdrometers and sites. Drop size and velocity distributions and developed KE–I relationships were device-specific and showed similarities for disdrometers of the same type across measurement sites. This hindered direct comparison of results from different types of disdrometers, even when placed at the same site. Thus, to discern spatial differences in rainfall characteristics the same type of measurement instrument should be used.

8103 Background: Monoclonal Gammopathy of Unknown Significance (MGUS) is characterized by the presence of a monoclonal immunoglobulin in the serum or the urine with no evidence of hematologic malignancy. A possible relationship between MGUS and increased incidence of NHM has been suggested in Caucasian populations. However, data in African Americans with MGUS are lacking. Methods: Non-MGUS controls were selected randomly from patients who did not have a paraprotein detected on electrophoresis (NMGUS) and were matched 2-to-1 to MGUS cases. Descriptive statistics and comparisons are presented to compare MGUS and NMGUS groups. Results: 492 male patients with MGUS patients were matched with 984 male NMGUS patients. 451 patients had abnormal serum protein studies (91.6%) and 40 had light chain disease (8.4%). Median age at diagnosis of MGUS was 68 years (28-81). 144 MGUS patients (29.2%) and 296 NMGUS patients (30%) had 1 or more NHM. The median age of diagnosis of 1st NHM was 70 (25-94) in the MGUS group and 68.4 in the NMGUS group (34.5-94.4). 19 MGUS patients (3.8%) and 27 NMGUS patients had 2 different types of NHM (2.7%). 1 MGUS patient (0.2%) and 3 NMGUS patients (0.3%) had 3 NHM. 57 patients had MGUS before NHM (11.5%) and 69 patients were diagnosed with MGUS after the diagnosis of NHM (14%), and median differences between diagnosis of MGUS and 1st NHM were 4 years (1-12 years) and 5 years (1-38 years) respectively. Types of NHM were comparable, and prostate cancer was the most prevalent NHM in both groups (15% of MGUS patients and 17% of NMGUS patients). Median time of follow up was 49.3 months for MGUS patients and 35.2 months for NMGUS patients 140 of the MGUS patients (28.4%) and 214 non-MGUS patients (21.75%) had died at data cut-off. Conclusions: Based on these observational data, prevalence and types of NHM appear to be comparable in MGUS and NMGUS African American patients. All cause mortality appears to be higher for NHM patients if they had MGUS. This pattern will need to be verified prospectively in a larger group of patients.

A New Species

Early plant introduction in Australia and NZ involved familiar European species and simple general principles. 'First-generation' pasture cultivars in both countries were based on naturalized or cultivated material originally brought by colonists. Later, imported material was systematically used to improve these established varieties and produce 'second-generation' cultivars more closely adapted to local ecological conditions and agronomic systems. This simple approach proved inadequate for new and difficult environments which required different types of plant, and new species were sometimes tried and discarded prematurely because their potential was not fully displayed in the limited material initially available. Experience with Sfylosanthes in Australia shows that full suites of germplasm are necessary to evaluate a new species properly, and that such material should be deliberately and systematically collected from areas of similar or more extreme climate, particular attention being paid to edaphic characteristics. To obtain suitable legumes for the cold dry high country of the South Island collections from homologous regions in places such as Chile, Argentina, Kashmir, and the USSR may be useful.

Kinship Ties

While previous studies focus on differences between family and nonfamily firms regarding CEO selection and executive compensation, this study investigates differences among family firms with different types of kinship ties. We find that, compared with family firms with close kinship ties, those with distant kinship ties are more likely to appoint a nonfamily CEO and to pay nonfamily executives lower salaries. This relationship is moderated by firm performance and family ownership. Based on evolutionary psychology, we propose that family firms with close versus distant kinships have different motivation levels to preserve socioemotional wealth.

Monitoring of Codling Moth (Cydia Pomonella L.) in Apple Orchards Using Two MethodsThe present studies were conducted in 1999-2001 in three apple orchards differing from each other by the system of cultivation, the type of agricultural treatments and chemical control of pests. Their purpose was to monitor codling moth (Cydia pomonellaL.) in different types of apple orchards using pheromone traps, finding out the relation between the occurrence of moths and the sum of effective temperatures as well as determining the number of wintering caterpillars of this species with the use of bands of corrugated paper. The analysis of male flight of codling moth on the basis of pheromone traps makes it possible to state the occurrence of two generations in each studied year. The maximum population of the first generation was observed in the second or third ten days of June, while that of the second generation in the first ten days of August. The moths flight began when the sum of effective temperatures was 109.2-145.2°C, and the mean diurnal temperature was 12.3-17.2°C.

This paper focuses on subject distribution in Greek and Chilean Spanish, both null subject languages, as evidenced in the oral production of monolingual and bilingual speakers. Narratives elicited from 40 monolinguals and 76 bilinguals of different types, namely, first-generation immigrants, heritage speakers and L2 speakers, were analysed to explore potential differences in expressing subject reference between the groups in monolingual and contact settings. The qualitative analysis of contexts of topic continuity and topic shift showed no overextension of the scope of the overt subject pronoun, expected to be found in the bilingual performance according to the Interface Hypothesis (Sorace, 2011, 2012) and previous research. The findings also show that the redundancy of lexical subjects observed in topic continuity contexts mostly involved felicitous (pragmatically appropriate) constructions. Moreover, while null subjects in topic shift were also found to be felicitous in both monolinguals and bilinguals, cases of ambiguity were observed in the bilingual performance in this discourse context.

Abstract A macrocytic blood picture was present in 62 per cent of 222 patients with various types of hepatic disease. Three different types of macrocytes were present in the blood films: a thin macrocyte, a target macrocyte and a thick macrocyte. Just as leukocytosis might be described as neutrophilic, basophilic or eosinophilic according to the predominate leukocyte present, so macrocytosis has been defined according to the predominate macrocyte present: thin macrocytosis, target macrocytosis and thick macrocytosis. This report deals with the first type, thin macrocytosis. 1. Thin macrocytosis is, by definition, the type of macrocytosis in which all the macrocytes are thin macrocytes. It is the commonest type of macrocytosis (59 per cent of all types of macrocytosis). 2. The thin macrocyte is a flattened erythrocyte. It has the same volume as the normal erythrocyte but is broader and thinner. As the diameter of the cell increases its thickness decreases. 3. Thin macrocytosis is caused by an alteration in erythropoiesis in the bone marrow and not by a flattening or swelling of normal erythrocytes in the peripheral circulation, as suggested by various workers, because: (a) Normal size erythrocytes transfused into the circulation of patients with thin macrocytosis do not become macrocytic. (b) Anisocytosis is increased. (c) The nucleated red cells in the marrow are macrocytic. 4.The thin macrocyte is produced by a macronormoblastic (or rarely atypical megaloblastic) type of maturation in the bone marrow. 5. This altered erythrocyte maturation which gives rise to thin macrocytosis is a specific response to nonspecific hepatic parenchymal cell damage. It occurs in a significant percentage of patients suffering from all types of parenchymal and obstructive hepatic disease. It does not occur in patients with simple fatty liver or obstructive jaundice of short duration where hepatic cells are not damaged. A deficiency of any known hematopoietic factor plays no part in the etiology of this disorder.

Contradictory Data

Abstract All these findings and the contradictory data in the literature show that the different types of nuclear projections in neutrophils, excluding the genetically determined drumsticks and sessile nodules, are nonspecific pseudosegments of the leukocytes. Their appearance depends on the segmentation, aging, and metabolism of the neutrophils. These features might be influenced by many factors, including possible hormonal effects. Our observations have shown, for instance, that androgens might induce an increase in the number of nuclear appendages. Although the appearance of these figures may be associated with certain diseases, it should not be regarded as a specific sign for a single pathologic or physiologic condition.
