Portunus pulchricristatus (Gordon, 1931): an addition to crab fauna of Pakistan (northern Arabian Sea)

Portunus pulchricristatus (Gordon, 1931) is a rare species, to date we have obtained only three specimens, two males and a berried female which can be easily identified with the help of existing descriptions and illustrations. Brief account of the Pakistan material is given below. One male specimen (measuring 11.0 mm in carapace length) has been deposited in the National Museum of Natural History, Leiden (Reg.No.D.42393) the other two specimens housed in the Marine Reference Collection and Resource Centre (MRCC Cat. No.BRAC.491). The abbreviations used are cl. for carapace length and cb. for carapace breadth.

instability of standing wave, global existence and blowup for the klein-gordon-zakharov system with different-degree nonlinearities

This paper discusses the Klein–Gordon–Zakharov system with different-degree nonlinearities in two and three space dimensions. Firstly, we prove the existence of standing wave with ground state by applying an intricate variational argument. Next, by introducing an auxiliary functional and an equivalent minimization problem, we obtain two invariant manifolds under the solution flow generated by the Cauchy problem to the aforementioned Klein–Gordon–Zakharov system. Furthermore, by constructing a type of constrained variational problem, utilizing the above two invariant manifolds as well as applying potential well argument and concavity method, we derive a sharp threshold for global existence and blowup. Then, combining the above results, we obtain two conclusions of how small the initial data are for the solution to exist globally by using dilation transformation. Finally, we prove a modified instability of standing wave to the system under study.

The effect of type of hip protector and resident characteristics on adherence to use of hip protectors in nursing and residential homes - an exploratory study

Objectives: To investigate the factors influencing the acceptability of hip protectors to residents of nursing and residential homes, especially the effect of hip protector type, and resident characteristics. Design: A randomised controlled trial with 12 weeks follow-up. Participants were randomised to receive either Safehips or HipSaverTM hip protectors. Setting/Participants: 109 residents aged 61 to 98 years from seven residential homes and two nursing homes in Northern Ireland. Main outcome measures: Percentage day-time use of the hip protectors over 12 weeks and ongoing use at 12 weeks. Results: 42% (119/285) of residents invited to enter the studyagreed to take part, and 109 started to wear the hip protectors. 43.1% (47/109) were still using them at 12 weeks. Mean percentage day-time use for all residents during 12 weeks was 48.6%. There was no significant difference in percentage day-time use (p=0.40), or use at 12 weeks (p=0.56) between the residents wearing Safehips and HipSaverTM protectors. Greater percentage daytime use of hip protectors was associated with being resident in a home for the elderlymentallyinfirm (75.1%, pp0.0005), having a low (12 or less) Barthel score (61.1%, pp0.0005), and having been injured in a fall in the last 12 months (57.3%, p=0.012). Conclusions: The type of hip protector appeared to make no difference to their continued use by residents. Residents with a historyof a fall and those who are physicallyand mentallyincapacitated appear to be more likelyto wear hip protectors. These residents, who are at high risk of falling, are also highlydependent on nursing staff. Efforts to increase hip protector use in residential and nursing home should focus on staff, who are in the best position to advise and influence residents and their relatives.

Factors affecting adherence to use of hip protectors amongst residents of nursing homes - A correlation study

Background: Hip protectors are protective pads designed to cover the greater trochanter and attenuate or disperse the force of a fall sufficiently to prevent a hip fracture. Promising results from randomised controlled trials in nursing homes have resulted in hip protectors being widely recommended in the health care literature and in national guidelines. Objectives: The objectives of the study were to identify characteristics of individual residents, and the organisational features of the homes in which they live, which may affect adherence to wearing hip protectors. Design: An observational, correlation study designed to identify factors related to adherence. Setting: Forty nursing and residential homes in the UK. Participants: 1346 residents of the homes who were not confined to bed and with no pressure sore on the hip. Methods: The introduction of an evidence-based policy to offer Safehips hip protectors to residents free of charge and with support from a nurse facilitator. Adherence to wearing the hip protectors was observed over 72 weeks. Results: Initial acceptance of the hip protectors was 37.2%. Continued adherence was 23.9% at 24 weeks; 23.2% at 48 weeks; and 19.9% at 72 weeks. Greater adherence was associated with the following individual resident characteristics: a greater degree of dependency (95% CI 1.39 - m3.78) and cognitive impairment (95% CI 1.01 - 2.98); being male rather than female (95% CI 1.06 - 2.48). Greater adherence was also associated with the following organisational characteristics of homes: fewer changes of senior manager during the study period (95% CI 1.01 - 8.51), and being resident in a home with a resident profile showing a greater proportion of residents with a higher degree of dependency (95% CI 1.04 - 1.27). There was wide a variation in the degree of success in implementation between homes (adherence of 0 - 100% at 24 weeks). Conclusions: Those implementing a policy of introducing hip protectors into nursing and residential homes should consider targeting residents with cognitive impairment. Such residents are at greater risk of hip fracture and appear to be more likely to continue wearing hip protectors. Those charged with implementing changes inpractice or policy should consider how the context for implementation can be optimised to increase the likelihood of success.
