For example sominex 25mg fast delivery, it is not a good idea to write in the Colorado study but rather to write in the study undertaken in Colorado or in the American study buy 25 mg sominex overnight delivery. The difference is that American is an adjective whereas Colorado is a proper noun that should not be used as an adjective purchase sominex 25 mg with visa. Therefore sominex 25 mg cheap, you cannot write This correlation study indicated a significant relation between drug concentration and markers of renal function in which correlation is used as an adjective. Moreover, the different types of research studies are described in Chapter 3 and a correlation study is not one of them. To avoid ambiguity, only use the word correlation when you are reporting results obtained by using a correlation coefficient. In describing ethnic groups, it is especially important not to use adjectives in place of a noun. This word is a plural noun and is the correct term to describe indigenous people. It is important never to use the term Aboriginals because Aboriginal is an adjective that does not have or need a plural form. Finally, remember that the word relation is the correct word to use to describe what one thing has to do with another as in We examined the relation between height and weight. The word relationship is only used to describe kinship or other bonds between people. Adjectives You don’t see something until you have the right metaphor to let you perceive it. Robert Stetson Shaw (physicist) Adjectives are words that are used to describe, or embellish, nouns. For example, in the phrase a random sample, the word random is an adjective that 219 Scientific Writing describes the type of sample that was recruited. In fact the words a and the are also adjectives in a strict sense but generally go by their titles of indefinite and definite article respectively. The word a is called an “indefinite article” because, like its companion an, it refers to an item that has not already been specifically mentioned. On the other hand, the word the is called the “definite article” because it refers to a particular item. When two or more adjectives are used in a list, they are separated by a comma as in small, unrepresentative samples and in large, cross-sectional survey. However, when adjectives are joined with a noun to form a noun cluster, as in non- insulin dependent diabetes or effective weight loss intervention strategies no comma is needed. In some sentences, the adjective almost acts like a noun when it is the object of the sentence. For example, in the phrase self-reported weights may be unreliable, the word unreliable is an adjective that describes self-reported weights but it acts as the object of the sentence. Although sentences can largely stand alone without adjectives, adjectives are needed to convey a precise rather than a general meaning. In 1995, results from the National Nutrition Survey in Australia suggested that 63% of men and 47% of women were either overweight or obese. Despite the impact of excess body weight on health, self-perception of body mass in the general population has not been properly investigated. The only information comes from small, unrepresentative samples of women, particularly younger women, or from national studies in which self-reported weights may be unreliable. Until reliable information of self-perceptions of body mass is collected, it is difficult to design effective weight loss intervention strategies. In this paper, we report information about adults’ perceptions of their own body mass. Notes on adjectives When using adjectives they need to be placed correctly to achieve a specific meaning. For example, in the sentence I was the only one who could use the cell sorter, the word only is used as an adjective to qualify the noun one. However, in the sentence I was the one who could only use the cell sorter, the word only is used as an adverb to qualify the verb use. By moving the word only, the sentence takes on a very different meaning. Also remember that every study is unique in that no two studies are ever identical so the adjective unique should not be used as a descriptor of a scientific study.

Chapter 3 Com m on orthopedic conditions from birth to alking None will grow more straight in his body than those who are laid free and loose in a sheltered, ample-spaced cradle. Neal Developmental displacement of the hip The term developmental displacement of the hip has replaced the previous more conﬁning and incriminatory terminology congenital dislocation of the hip. Although the vast majority of idiopathic hip dislocations are recognizable at birth, a number of hips will not have sufﬁcient clinical ﬁndings of displacement until later in the ﬁrst year of life (at three to nine months). The implications of this terminology are obvious and the broader spectrum should help clarify our understanding of the evolution of hip displacement, particularly in those in which spontaneous relocation does not occur. This condition has its origins of recognition with the ancients; Hippocrates aptly described its existence and its treatment. Current concepts of etiology focus primarily on intrauterine and extrauterine factors. Females, ﬁrst-born children (pressure from strong maternal abdominal muscles), breech malposition and delivery, large body size, oligohydramnios, and genetics have all been strongly implicated as risk factors. This condition is associated with congenital muscular torticollis approximately 20 percent of the time. In those regions of the world where hip extension “strapping” and “cradleboards” Common orthopedic conditions from birth to walking 24 are utilized on newborns, the incidence of developmental displacement of the hip occurs approximately 40–50 percent of the time. Established dislocation at birth is nearly always associated with other disorders such as cerebral palsy, myelodysplasia, arthrogryposis and other syndromes. It is generally believed that undue pressure on the hip, combined with a lax hip joint capsule (i.

The hip is initially examined with the baby supine and the hips ﬂexed to 90 degrees, and with gentle but ﬁrm downward pressure on the femurs to ﬁx the potentially moveable pelvis to the examination table. The ﬁngers are positioned to provide for downward pressure on the femurs and to allow for direct vision of the thighs when abduction and adduction movements are attempted. Asymmetry of the thigh creases is readily appreciated in this position, as are differences in the height of the knees (Figure 3. The thighs are then gently and slowly parted (abducted with the middle or ring ﬁngers palpating the greater trochanters). In unstable but “reducible” hips a discernible “clunk” will often be discerned in the neonate but commonly may recede to a “click” over the ensuing few months and then eventually disappear. The later discernible “click” obtained in near full abduction is usually a sign that the acetabular labrum has not ﬁrmly attached and stabilized, but is a sign of improved stability. If a true dislocation is evident, abduction will be clearly limited, as the head will not enter into the 25 Developmental displacement of the hip acetabular conﬁnes with attempts at reduction. A positive Barlow sign is actually a provocative dislocation or subluxation test, and is elicited using the thumb and ﬁngers to laterally move the femoral head out of the acetabular conﬁnes by lateral pressure of the inner aspect of the thigh (Figure 3. Perhaps the most valuable sign of hip instability (subluxation or dislocation) is the “pistoning” or “telescoping” sign. It is generally elicited by stabilizing the pelvis with one hand ﬁrmly against the anterior iliac spine, grasping the femur in the other hand, then “pumping” downward and upward in a vertical direction with the hip ﬂexed to 90 degrees (Figure 3.
