Six cuprous oxide antifouling paints, ranging from low to high quality, were exposed to settling larvae of Spirorbis lamellosa Lamarck and S. convexis Wisely. All paints were newly immersed (up to 11 days). The poor quality paint allowed larvae to attach under laboratory conditions or in the sea, and these larvae developed the characteristic spiral tubes of the adults before dying (post-attachment mortality). Under similar conditions the intermediate and high quality paints killed the larvae before they could attach (pre-attachment mortality). These results are compared with those obtained recently for barnacle, bryozoan, and bivalve mollusc larvae.

Sperm Immobilization

SummaryTo explore whether different polyvinylpyrrolidone (PVP) concentrations affect the results of intracytoplasmic sperm injection (ICSI), a prospective study was conducted for 194 couples undergoing 210 ICSI therapy cycles. These cycles were divided into three groups (10, 7 and 5% groups) using the corresponding concentration of PVP for sperm immobilization. The main outcome measures were analyzed. Results indicated that, with a decrease in PVP concentrations, all of the main outcome measures increased. In particular, the high-quality cleavage embryo rate in the 7% group was significantly lower than in the 5% group (P < 0.01), and the cleavage, high-quality cleavage embryo, and high-quality blastocyst rates in the 5% group were significantly higher than those in the 10% group (all P < 0.001). For high-/intermediate-quality semen, all of the main outcome measures were significantly increased with 5% PVP. For the poor-quality semen, only the high-quality cleavage embryo and high-quality blastocyst rates were significantly higher in the 5% group. Therefore, lowering PVP concentrations greatly promoted the development of embryos in ICSI cycles, with an optimal concentration of 5% for ICSI.

A comprehensive field data were collated analyzed and processed for the validation of open source bathymetry data GEBCO 30 sec arc resolution data in the selected location of the Red sea. Different software and techniques were used to verify the quality of GEBCO data in the field conditions. The image analysis using different software proves the poor quality and resolution of the GEBCO data in the nearshore areas. The analyses also brought out the complex topographical nature of the Red sea and precautions for the usage of open source bathymetric data in the nearshore areas of the Red sea, where high quality and fine resolution data required. The different statistical analyses also verified the results of image analysis. The statistical analysis also shows the poor quality and course resolution of the GEBCO 30sec resolution data in the Red sea especially nearshore areas. The study recommends hydrographic survey data for the nearshore areas, where high quality and resolution data are needed

The 19Th Century

Benefiting from the consequences of cultural and scientific development which kicked off in the 19th century, the Romanian space also felt the lags up till then. The development and organisation deficit of science and culture, the poor quality of their relationships with the social complex, were augmented frequently not necessarily by the poor quality of the Romanian scholars, but by a certain superficiality of theirs in the approach and presentation of the treated matters. Trying to confer reliability, accuracy and transparency to the scientific construction in which he took part, A. Philippide often felt in a negative manner some of the scientific behaviours and results presented by his generation colleagues. In this context, beyond the high quality of his results and his highly responsible attitude, the way in which the scholar from Iași tried to improve the process was the scientific polemic.

The validity of the chondrichthyan species Petalodus ohioensis Safford 1853, has long been in doubt due to the poor quality of the published figures and the unknown whereabouts of the holotype. That situation changed with the discovery of casts of the holotype in the collections of the Yale Peabody Museum of Natural History. The quality of the casts is poor, but sufficient to establish P. ohioensis as a valid species and as a senior synonym of P. alleghaniensis Leidy 1856. Recently, casts of the holotype of much better quality were found in the collections of the Field Museum of Natural History, accompanied by documentation indicating that they were likely obtained directly from Safford by O.P. Hay in 1896. The Field Museum casts clearly show the bands of ridges at the base of the crown on the labial and lingual sides, which are not visible on the Yale Peabody Museum casts.

The article discusses the experience of teaching and conducting spirometry of general practitioners as part of the RESPECT study (RESearch on the PrEvalence and the diagnosis of COPD and its Tobacco-related aetiology). A total of 33 trained in spirometry general practitioners performed a study of 3119 patients. Quality criteria met 84.1% of spirometric studies. The analysis of the most common mistakes made by doctors during the forced expiratory maneuver is included. The most frequent errors were expiration exhalation of less than 6s (54%), non-maximal effort throughout the test and lack of reproducibility (11.3%). Independent predictors of poor spirogram quality were male gender, obstruction (FEV1 /FVC<0.7), and the center where the study was performed. The number of good-quality spirograms ranged from 96.1% (95% CI 83.2–110.4) to 59.8% (95% CI 49.6–71.4) depending on the center. Subsequently, an analysis of the reasons behind the poor quality of research in individual centers was conducted and the identified shortcomings were eliminated. The poor quality of the spirograms was associated either with the errors of the doctors who undertook the study or with the technical malfunctions of the spirometer.

AbstractIt has become a necessary requirement of the time for colleges to carry out enterprise education to produce high-quality personnel with entrepreneur spirit and ability. It is discussed at the beginning of this article that the purpose and status quo of the enterprise education for college students in China and then the reasons for the poor condition in enterprise education are explored. It is found out that colleges do not provide an effective systematic platform for enterprise education; necessary personnel are not provided for such purpose in the teaching staff in Chinese colleges; in actual operation practical effect is not achieved in the moral training in colleges. Therefore, new concept in moral training must be introduced and first-rate teaching staff must be provided for the effective enterprise education. Special courses must also be systematically compiled for the purpose.

Epidemiological studies in rural Mexico have shown the role of poor quality water in gastrointestinal disease incidence. This led to the establishment of a program, which included the assessment of inexpensive systems for household treatment of drinking water. We describe the main features of a hand carved stone filter evaluated over 6 months under laboratory conditions and 6 months under household conditions. The filter had a capacity of 5L and an average volume of 18L/d filtered water (the temperature of which was always an average 4°C lower than the influent). Average bacterial removals under laboratory conditions were 98% for total and faecal coliforms (TC, FC), 96% for faecal streptococci (FS), 99% for Pseudomonas aeruginosa and 100% for helminth eggs and protozoan cysts. During the field evaluation removals were 80–100% TC, 45–95% FC and 8–93% FS due to the different qualities of influent water and the operation conditions. Nevertheless, the filters represented an immediate mitigation measure of the health risks associated with the continuous ingestion of microbiologically unsafe waters.

The quality of metadata is a crucial determinant of usability/interpretability of data. This paper draws attention to the poor quality of India’s government statistics and the paucity of metadata necessary to understand the problems. The paper suggests that there has been a decline in India both in terms of the availability and quality of metadata for key government sources of information including maps, decennial population censuses and National Sample Surveys amidst growing sophistication in the understanding of metadata. The poor quality of metadata impairs cross-sectional as well as inter-temporal comparisons and policymaking apart from concealing biases and lapses of government statisticians. The paper draws on the experience of three states – erstwhile Jammu and Kashmir, Manipur and Nagaland – where government statistics have been affected by serious errors that are not well-understood due to the lack of adequate metadata.
