The problem of "understandinq" electron microscope imaqes becomes more acute as the resolution is improved. The naive interpretation of an imaqe as representinq the projection of an atom density becomes less and less appropriate. We are increasinqly forced to face the complexities of coherent imaqinq of what are essentially phase objects. Most electron microscopists are now aware that, for very thin weakly scatterinq objects such as thin unstained bioloqical specimens, hiqh resolution imaqes are best obtained near the optimum defocus, as prescribed by Scherzer, where the phase contrast imaqe qives a qood representation of the projected potential, apart from a lack of information on the lower spatial frequencies. But phase contrast imaqinq is never simple except in idealized limitinq cases.

Lack Of Information

An understanding of the specific interactions of actin with regulatory proteins has been limited by the lack of information about the structure of the actin filament. Molecular actin has been studied in actin-DNase I complexes by single crystal X-ray analysis, to a resolution of about 0.6nm, and in the electron microscope where two dimensional actin sheets have been reconstructed to a maximum resolution of 1.5nm. While these studies have shown something of the structure of individual actin molecules, essential information about the orientation of actin in the filament is still unavailable.The work of Egelman & DeRosier has, however, suggested a method which could be used to provide an initial quantitative estimate of the orientation of actin within the filament. This method involves the quantitative comparison of computed diffraction data from single actin filaments with diffraction data derived from synthetic filaments constructed using the molecular model of actin as a building block. Their preliminary work was conducted using a model consisting of two juxtaposed spheres of equal size.

Amphibians have paired muscular pump organs, called “lymph heart”, which rhythmically pump back the lymph from the large subcutaneous lymph sacs into the veins. The structure and ultrastructure of these organs is well known but to date there is a lack of information about the innervation of lymph hearts. Therefore has been carried out an ultrastructural study in order to study the distribution of the nerve fibers, and the morphology of the neuromuscular junctions in the lymph heart wall.

Abstract. Background: Early identification and appropriate referral services are priorities to prevent suicide. Aims: The aim of this study was to describe patterns of identification and referrals among three behavioral health centers and determine whether youth demographic factors and type of training received by providers were associated with identification and referral patterns. Method: The Early Identification Referral Forms were used to gather the data of interest among 820 youth aged 10–24 years who were screened for suicide risk (females = 53.8%). Descriptive statistics and binary logistic regressions were conducted to examine significant associations. Results: Significant associations between gender, race, and age and screening positive for suicide were found. Age and race were significantly associated with different patterns of referrals and/or services received by youths. For providers, being trained in Counseling on Access to Lethal Means was positively associated with number of referrals to inpatient services. Limitations: The correlational nature of the study and lack of information about suicide risk and comorbidity of psychiatric symptoms limit the implications of the findings. Conclusion: The results highlight the importance of considering demographic factors when identifying and referring youth at risk to ensure standard yet culturally appropriate procedures to prevent suicide.

Levels Of Support

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.

In recent years as public in general and specialist have been showing big interest to the matters of reading. According to discussion and launch of the “Support and Development of Reading National Program”, many Russian libraries are organizing the large-scale events like marathons, lecture cycles, bibliographic trainings etc. which should draw attention of different social groups to reading. The individual forms of attraction to reading are used much rare. To author’s mind the main reason of such an issue has to be the lack of information about forms and methods of attraction to reading.

This empirical study show that the impact of all styles was well moderate. The means of effect of all styles were less than 3 out of 5. It means the expected impact of transformational affect upon the all dimensions of the activities, are not expected due to the traditional styles of leadership and the lack of information about the transformational leadership styles which can guide leaders to use such styles in the organization which may be this results due to lack of trained leaders and necessary knowledge with the leaders in all universities about transformational styles the traditional form of the leadership styles which used by the university leaders affect the communication between all levels of the administration and the faculty members which has consequence because decrease in motivation and a self-consideration from the administration.

Tea is an imperative beverage elsewhere in the world.  The need and demand for tea are increasing day by day.  Tea Association of USA expects continued growth in tea sales due to awareness on its health benefits. There are more than 3000 kinds of tea varieties are there but only four varieties are widely used. The authors investigated the opinion on sustainability perspectives and problems faced by them while they intend to buy. Willing Participants are included in survey with the sample size of 237.  The correlation result revealed that there is a positive relationship between educational qualification and sustainability perspectives of tea products among consumers. .  It is also found that lack of information and high price were the major problems faced by tea consumers while intend to buy sustainable tea. So the tea manufacturers and processors must throw light on these issues to improve its preference among consumers.

This paper describes women with disabilities who are facing legal cases, most of which are related to cases of sexual violence. The handling of cases of women with disabilities experienced problems, namely: law enforcers did not have a maximum understanding of the disabled; 2) limited access; 3) limited evidence: 4) difficulty communicating; 5) the community does not want to be a witness; 6) length of legal process; 7) lack of knowledge about the law; 8) there is no assistance in the police department during inspections, the examination room is not easily accessible, and the lack of information for victims; 9) the prosecutor does not provide information if the file has been delegated and; 10) judges have difficulty communicating. Therefore, law enforcers must have the same perception of diffables, so that they get legal justice.
