A re-evaluation of the age of the formations comprising the Eagle Plain Group of northern Yukon was necessitated by widely disparate age determinations in recent years from various authors. Maximum age estimates for the base of the group have varied from middle Albian to Cenomanian, and age estimates for the uppermost strata varied by an even greater range, from Cenomanian to late Maastrichtian. A re-examination of new and archival foraminiferal and palynological data indicates an age range of Cenomanian to late Maastrichtian for the Eagle Plain Group. The late Maastrichtian age is derived from palynology from the northeasternmost area of Eagle Plain. However, the stratigraphic relationship of these youngest beds within Eagle Plain Group remains uncertain. Marine strata of the Eagle Plain Group contain foraminiferal indices that correlate with long-established regional foraminiferal zones from the Mackenzie Delta area. The Cenomanian Zone of Trochammina superstes occurs in the Parkin and Boundary Creek formations of Eagle Plain and Mackenzie Delta, respectively. The Haplophragmoides bilobatus and overlying Glaphyrammina spirocompressa zones occur in the Burnthill Creek and Smoking Hills formations of Eagle Plain and Mackenzie Delta, respectively. Reworked microfossils are a conspicuous feature of strata within the Eagle Plain Group. The basal sandstone of the Parkin Formation, for example, contains an assemblage of foraminifera that is entirely reworked. Palynomorph assemblages through the Eagle Plain Group have been estimated at as much as 99% reworked in some strata.

Abstract. Original published evidence indicated an age range of early Lower Miocene to early Middle Miocene for Globigerina silt samples from the English Channel and the Western Approaches. Suggested younger ages for these samples are refuted on the basis of planktonic foraminifera and calcareous nannoplankton.

Depression is very frequent in Parkinson’s disease (PD) and largely unrecognized by neurologists, emphasizing the need of an approach to psychiatric symptoms by non psychiatrists in order to ensure an early diagnosis of depression in PD; clinical characteristics and the prevalence rate of depression in PD were evaluated and the relationship of depression in PD with other variables were determined. Sixty PD subjects, who fulfilled the clinical criteria for primary PD, 56,6% males, age range from 44 to 85 years old, in different stages of the disease were investigated. All subjects were submitted to the UPDRS-III, V and VI, Clinical Interview Schedule and the Hamilton depression scale. A significant correlation was found between depression and UPDRS-III, V and VI, anxiety and irritability. The frequency of depression in PD in this study was nearly 40% possessing specific features. Structured interviews and evaluation scales are essential for an accurate diagnosis and proper treatment of depression in PD.

The present study examines the relationship of depression and the neuropsychologicalfunction of attention, planning and auditory verbal learning and memory among individualswith HIV/AIDS. 200 subjects who were HIV/AIDS positive (100 males and 100 females) andwere within age range of 20 to 50 years and minimum education level of 8th standard weretaken. The result indicates that Depression slows down the performance of attention; alsodepression most likely decreases the function of auditory verbal learning and memory

Suicide is described as death caused by self-directed injurious behavior with any intent to die as a result of the behavior. Adolescence is a period of marked risk for suicide. This study was carried out to find out the relationship of parenting style and suicidal ideation of adolescents. A sample of (N= 200) with age range of 13 to 19 years from different schools of Khyber Pakhtun Khwa, Pakistan was selected. Two instruments were used in study:  Parental Authority Questionnaire (PAQ), and Suicidal Risk Scale (SRS). Pearson partial correlation was applied to analyze the data. The findings shows permissive mother parenting style is significantly positively correlated with authoritarian mother parenting, permissive father parenting, authoritarian father parenting, and suicidal ideation. Whereas, authoritarian mother parenting style significantly positively correlated with permissive father parenting, authoritarian father parenting, and suicidal ideation. Meanwhile authoritative/flexible mother parenting style is significantly negatively correlated with permissive father parenting, authoritarian father parenting, and suicidal ideation.

Menarche is a sign of the proper functioning of a woman's reproductive organs when having her first menstruation and is common in the age range of 10-16 years. Menarche is influenced by several factors, one of which is nutritional status. According to Noviyanti research (2016) nutrition affects a girl's sexual maturity so that it affects the slowness of menarche. Similarly, research conducted by Munda (2016) that students with overweight nutritional status faster experienced menarche compared to students who have normal nutritional status and underweight. This study aims to find out the relationship of nutritional status to the age of menarche grade VII students in Pesantren Bahrul Ulum. This research method uses descriptive method with cross sectional research design. This research was conducted in SDN 007 Rambah. The sample of this study amounted to 45 respondents. Data collection uses simple correlation and linear regression tests. The results of this study stated that the average nutritional status of grade VII students is 21.60Kg /m2, and the nutritional status of students is at least 16.90 Kg / m2 and the highest nutritional status is 27.60 Kg / m2 with an average age of menarche 12.11 years. The conclusion of this study is that there is no relationship of nutritional status with menarche age in grade VII students in Pesantren Bahrul Ulum with a value of p= 0.036.

<div><p><em>The aim of this study is to identify the Anthropometric and profiles of sub-Junior National level Boxers and also to find out the relationship of Anthropometric profiles and psychomotor abilities of the sub-Junior National level Boxers.</em><em> </em><em>A total 22 female Boxers (11 medalists and 11 non-medalists) age range between 12<sup>th</sup> to 16<sup>th</sup> years will be select from SAI, SAG, Imphal centers. Selected Anthropometric variables (Body composition) will be taken on each Boxer. Total Psychomotor ability scores (Speed, Agility, Differentiation, Orientation, Balance, Rhythm Ability) will be taken. For interpretation of data a comparative analysis of the selected variable, the “t” test was applied. The data of both groups were collected separately for all the variables. Statistic such as mean and standard deviation was computed. The level of significance was set at 0.05. It was found that in BMI, BMR do not have significant deference between the Manipur and West Bengal female Boxers and significant deference was found on Speed, Agility, Differentiation, Orientation, Balance, Rhythm Ability.</em></p></div>

✓ A series of 8814 head-injured patients admitted to 41 hospitals in three separate metropolitan areas were prospectively studied. Of these, 1906 patients (21.6%) were 14 years of age or less. This “pediatric population” was compared to the remaining “adult population” for mechanism of injury, admission Glasgow Coma Scale score, motor score, blood pressure, pupillary reactivity, the presence of associated injuries, and the presence of subdural or epidural hematoma. The relationship of each of these factors was then correlated with posttraumatic mortality. Except for patients found to have subdural hematoma and those who were profoundly hypotensive, the pediatric patients exhibited a significantly lower mortality rate compared to the adults, thus confirming this generally held view. This study indicates that age itself, even within the pediatric age range, is a major independent factor affecting the mortality rate in head-injured patients.
