Abstract
OBJECTIVES To estimate global and regional trends from 2000 to 2020 of the number of persons visually impaired by glaucoma and their proportion of the total number of vision-impaired individuals. METHODS A systematic review and meta-analysis of published population studies and grey literature from 2000 to 2020 was carried out to estimate global and regional trends in number of people with vision loss due to glaucoma. Moderate or severe vision loss (MSVI) was defined as visual acuity of 6/60 or better but <6/18 (moderate) and visual acuity of 3/60 or better but <6/60 (severe vision loss). Blindness was defined as presenting visual acuity <3/60. RESULTS Globally, in 2020, 3.61 million people were blind and nearly 4.14 million were visually impaired by glaucoma. Glaucoma accounted for 8.39% (95% uncertainty intervals [UIs]: 6.54, 10.29) of all blindness and 1.41% (95% UI: 1.10, 1.75) of all MSVI. Regionally, the highest proportion of blindness relating to glaucoma was found in high-income countries (26.12% [95% UI: 20.72, 32.09]), while the region with the highest age-standardized prevalence of glaucoma-related blindness and MSVI was Sub-Saharan Africa. Between 2000 and 2020, global age-standardized prevalence of glaucoma-related blindness among adults ≥50 years decreased by 26.06% among males (95% UI: 25.87, 26.24), and by 21.75% among females (95% UI: 21.54, 21.96), while MSVI due to glaucoma increased by 3.7% among males (95% UI: 3.42, 3.98), and by 7.3% in females (95% UI: 7.01, 7.59). CONCLUSIONS Within the last two decades, glaucoma has remained a major cause of blindness globally and regionally.

Abstract
SIGNIFICANCE Quality refractive error care is essential for reducing vision impairment. Quality indicators and standardized approaches for assessing the quality of refractive error care need to be established. PURPOSE This study aimed to develop a set of indicators for assessing the quality of refractive error care and test their applicability in a real-world setting using unannounced standardized patients (USPs). METHODS Patient outcomes and three quality of refractive error care (Q.REC) indicators (1, optimally prescribed spectacles; 2, adequately prescribed spectacles; 3, vector dioptric distance) were developed using existing literature, refraction training standards, and consulting educators. Twenty-one USPs with various refractive errors were trained to visit optical stores across Vietnam to have a refraction, observe techniques, and order spectacles. Spectacles were assessed against each Q.REC indicator and tested for associations with vision and comfort. RESULTS Overall, 44.1% (184/417) of spectacles provided good vision and comfort. Of the spectacles that met Q.REC indicators 1 and 2, 62.5 and 54.9%, respectively, provided both good vision and comfort. Optimally prescribed spectacles (indicator 1) were significantly more likely to provide good vision and comfort independently compared with spectacles that did not meet any indicator (good vision: 94.6 vs. 85.0%, P = .01; comfortable: 66.1 vs. 36.3%, P < .01). Adequately prescribed spectacles (indicator 2) were more likely to provide good comfort compared with spectacles not meeting any indicator (57.7 vs. 36.3%, P < .01); however, vision outcomes were not significantly different (85.9 vs. 85.0%, P = .90). Good vision was associated with a lower mean vector dioptric distance (P < .01) but not with comfort (P = .52). CONCLUSIONS The optimally prescribed spectacles indicator is a promising approach for assessing the quality of refractive error care without additional assessments of vision and comfort. Using USPs is a practical approach and could be used as a standardized method for evaluating the quality of refractive error care.

Abstract
In order to determine influencing parameters on energy production of the IFBB process, herbage from a lowland hay meadow (Arrhenaterion) was sampled and ensiled at eight dates between 27 April and 21 June 2007. The silage from each date was processed in six IFBB treatments with and without hydrothermal conditioning at different temperatures. Methane yields and higher heating values were determined and an energy balance was calculated with whole-crop digestion (WCD) of the silage as reference system. Maximum net energy yields were 10.2 MWh ha(-1) for the IFBB treatment without hydrothermal conditioning and 9.0 MWh ha(-1) for the treatment with hydrothermal conditioning at 50 °C. WCD achieved a maximum net energy yield of 3.7 MWh ha(-1). Energy conversion efficiency ranged from 0.24 to 0.54 and was predicted with high accuracy by temperature of hydrothermal conditioning as well as concentration of neutral detergent fibre and dry matter in the silage (R(2)=0.90).

Abstract
The IFBB process, which separates biomass into a press fluid for biogas production and a press cake for combustion, is aimed at converting low-input high-diversity grasslands into energy, which is problematic with conventional conversion techniques. Herbage from a lowland hay meadow (Arrhenaterion) was sampled on eight dates between 24 April and 21 June 2007. Silage from each date was processed in six treatments without and with hydrothermal conditioning at different temperatures. The impact on mass flows of plant compounds and on elemental concentrations in the press cake was investigated. Elements detrimental for combustion were significantly reduced in the press cake compared to the silage. Mass flows and elemental concentrations in the press cake were strongly influenced by conditioning temperature as well as concentration of neutral detergent fiber and dry matter in the silage (R(2) from 0.70 to 0.99). Press cakes of late sampling dates were considered best suitable for combustion.

Abstract
We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806-20 and 190 lesser events from SGR 1806-20 and SGR 1900+14. The unprecedented sensitivity of the detectors allows us to set the most stringent limits on transient GW amplitudes published to date. We find upper limit estimates on the model-dependent isotropic GW emission energies (at a nominal distance of 10 kpc) between 3x10;{45} and 9x10;{52} erg depending on waveform type, detector antenna factors and noise characteristics at the time of the burst. These upper limits are within the theoretically predicted range of some SGR models.

Abstract
"Using survey and ethnographic data gathered in Nepal, this paper examines the implications of change in work, living experiences, and the marriage process for subsequent inter-familial relationships exemplified by cross-cousin marriage and the provision of brideservice. Hypotheses are developed which consider the impact of community context on these behaviors; these are tested in logistic regression analyses for the first marriages of all 430 ever-married women in the community. Cross-cousin marriage and brideservice are shown to be related to prior familial characteristics, life-course experience, and elements of the marriage process in ways that are significantly conditioned by community history and proximity to urban centers."

Abstract
The purpose of this study was to investigate performance on the Random-Dot E (RDE) stereotest under binocular and monocular non-stereoscopic viewing conditions. Sixteen adult observers with normal vision were tested with the RDE stereotest. Four new RDE tests were shown to each observer in varying combinations of monocular viewing, binocular but non-stereoscopic viewing, and normal binocular viewing conditions. The test conditions were masked (where possible) and were presented in pseudo-random order. Control experiments were also conducted using the Frisby stereotest. Fifteen of the sixteen observers could discern some differences between the plates monocularly and therefore satisfied the passing criterion of the RDE test. Under these conditions, no observers could discern the stereoscopic E figure nor did any observer report a sensation of depth. No observer satisfied the passing criterion of the Frisby test monocularly. We conclude that caution should be used when interpreting results from the RDE stereotest, since adult observers could discern some differences between the test plates monocularly.

Abstract
Although site-specific direction of drugs within an organism would benefit patients with many diseases, active drug targeting is clinically not yet possible. To overcome some of the problems associated with active drug targeting, we have developed a magnetic fluid to which drugs, cytokines, and other molecules can be chemically bound to enable those agents to be directed within an organism by high-energy magnetic fields. In the first part of this study, various concentrations of the magnetic fluid were tested in rats and immunosuppressed nude mice with regard to subjective and objective tolerance. In the second part, the same parameters were evaluated after administration of the ferrofluid to which epirubicin (4'-epidoxorubicin) was chemically bound. Finally, two forms of therapy with the magnetic fluid were tested: tumor treatment by mechanical occlusion with the ferrofluid in high concentrations; and magnetic drug targeting, using small amounts of the ferrofluid as a vehicle to concentrate epirubicin locally in tumors. As a result, the ferrofluid did not cause major laboratory abnormalities; there was no LD50. With very high concentrations of the ferrofluid, animals showed lethargy for 1-2 days. There were no intolerances with the epirubicin-bound ferrofluid as well. Both forms of treatment led to complete tumor responses in an experimental human kidney as well as in a xenotransplanted colon carcinoma model. Thus, the magnetic fluid is a safe agent, which can be used in different ways for local forms of cancer treatment in conjunction with high-energy magnetic fields.

Abstract
Using data from a Nepali population, this analysis argues that marriage style and postmarital living arrangements affect coital frequency to produce variations in the timing of first birth after marriage. Event history analysis of the first birth interval for 149 women suggests that women's autonomy in marriage decisions and marriage to cross-cousins accelerate the pace of entry into first birth. Extended-household residence with reduced natal kin contact, on the other hand, significantly lengthens the first birth interval. These findings are consistent with previous arguments in the literature while offering new evidence for the impact of extended-family residence on fertility.
