Sibling Rivalry
Sibling rivalry is a type of competition or animosity among siblings, whether blood related or not. Siblings generally spend more time together during childhood than they do with parents. The sibling bond is often complicated and is influenced by factors such as parental treatment, birth order, personality, and people and experiences outside the family. According to child psychologist Sylvia Rimm, sibling rivalry is particularly intense when children are very close in age and of the same gender, or where one child is intellectually gifted. According to observational studies by Judy Dunn, children are sensitive from the age of one year to differences in parental treatment. From 18 months on siblings can understand family rules and know how to comfort and be kind to each other. By 3 years old, children have a sophisticated grasp of social rules, can evaluate themselves in relation to their siblings, and know how to adapt to circumstances within the family. Sibling rivalry often continues throughout childhood and can be very frustrating and stressful to parents. Adolescents fight for the same reasons younger children fight, but they are better equipped physically and intellectually to hurt and be hurt by each other. Physical and emotional changes cause pressures in the teenage years, as do changing relationships with parents and friends. Fighting with siblings as a way to get parental attention may increase in adolescence. One study found that the age group 10 to 15 reported the highest level of competition between siblings.
Sibling rivalry can continue into adulthood and sibling relationships can change dramatically over the years. Events such as a parent’s illness may bring siblings closer together, whereas marriage may drive them apart, particularly if the in-law relationship is strained. Approximately one-third of adults describe their relationship with siblings as rivalrous or distant. However, rivalry often lessens over time. At least 80 percent of siblings over age 60 enjoy close ties.

Desalination is a process that extracts minerals from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation. One by-product of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water sources.
Due to its energy consumption, desalinating sea water is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation. However, these alternatives are not always available and depletion of reserves is a critical problem worldwide. Currently, approximately 1% of the world's population is dependent on desalinated water to meet daily needs, but the UN expects that 14% of the world's population will encounter water scarcity by 2025. Desalination is particularly relevant in dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams for water.
According to the International Desalination Association, in June 2015, 18,426 desalination plants operated worldwide, producing 86.8 million cubic meters per day, providing water for 300 million people. This number increased from 78.4 million cubic meters in 2013 a 10.71% increase in 2 years. The single largest desalination project is Ras Al-Khair in Saudi Arabia, which produced 1,025,000 cubic meters per day in 2014, although this plant is expected to be surpassed by a plant in California. Kuwait produces a higher proportion of its water than any other country, totaling 100% of its water use.

The changes in body weight and composition were examined in broilers that either had immediate access to feed and water or had not been fed for 48 h posthatch. Chicks without access to feed decreased in BW by 7.8% in the 48 h posthatch, which was equivalent to 5.3 kcal/45 g chick/d. However, during this period the small intestines increased in weight and protein content by 80% or more. The decrease in yolk fat and protein could account for most of the changes in body composition in the feed-deprived chick. In contrast, fed chicks grew by 5 g and used 4.5 kcal/d for maintenance; during this period small intestines increased in weight by 110%. Intestinal absorption of exogenous nutrients was determined from hatch through 4 d posthatch by administration of a bolus of labeled glucose, methionine, or oleic acid, together with a nonabsorbed reference substance. Absorption of fatty acids was more than 80% at hatch and was higher than that of glucose and methionine, which was low especially when the bolus was administered as a solution. Absorption of all components tested increased with age and was more than 80% on Day 4. Duodenal in situ uptake determinations in hatching chicks indicated that uptake of oleic acid was high from yolk and saline solutions compared with glucose and methionine, which exhibited low uptake from yolk but higher uptake from saline solutions. These studies indicate that, although the small intestine has the capacity to absorb carbohydrates and amino acids at hatch, uptake may be dependant on the development of suitable conditions, including sufficient pancreatic and brush border enzymes for digestion and adequate sodium for function of the glucose-sodium cotransporters.

The exhibition of Egyptian antiquities currently at the Grand Palais in Paris possesses an international importance comparable in the past 40 years only with the exhibition of Chinese art organised by Beijing at the Petit Palais in 1973. Instead of famous works of art from museums or private collections, it displays a great number of new archaeological discoveries, including some unexpected chef d'oeuvres, all but one unpublished before now. Shown first in Berlin, it has been organised by a French underwater archaeologist, Franck Goddio (Fig. 5), to present the results of well over 10 years of his research along the shores of the Nile delta. [FIGURE 5 OMITTED] During the first millennium AD, several earthquakes and floods between Alexandria and the western mouth of the Nile caused the coastline to sink into the sea along a stretch of some 30 kilometres. ThonisHeraklion, at the end of the Canopic branch of the Nile, and the neighbouring city of Kanopos-East disappeared during the 7th-8th century. The inundation of Alexandria's eastern harbour, called by the Romans Portus Magnus, occurred between the mid 4th and the early 14th centuries AD. Goddio has been assisted by a skilful team drawn from Egypt, France, Germany and elsewhere. But the vision, the will and the tenacity that have kept together the complex machinery of the enterprise are his. Now over 50, Goddio has wide experience of diving in the Pacific and the Atlantic. The results of his long underwater search presented in the Grand Palais are in many ways comparable to the rediscovery of Troy by Schliemann in the 19th century and of Tutankhamun's tomb by Lord Carnarvon and Howard Carter in the 1920s. It is true that among the underwater ruins that he has explored, Goddio has not recovered any gold and silver treasure comparable with the findings of Schliemann and Carter. As far as gold is concerned, the show includes only some coins, earrings, rings, amulets and crosses. However, the discovery under the sea after so many centuries of three ancient ports enables Goddio to take his place not only beside Schliemann and Carter but also...

Rosemary McCleod has one of this country's largest collections of women's handcrafts. When it was exhibited at the Dowse gallery, almost 40,000 women of all ages came to see it, and the idea for this book was born. In her own words: "My collection began when I held onto items made by women in my own family when they died. I still have items made by my great grandmother, grandmother and my mother. I began collecting other objects about 20 years ago. I found them in thrift shops and bought them because they seemed to tell a story I knew from my own background." In Thrift to Fantasy, Rosemary has used them to brilliant effect, creating a unique social and personal history of their makers - women and girls who dreamed about a life beyond the farm gate and worked those dreams into reality, using the simple materials they had to hand. From rag rugs to felt handbags, from patchwork quilts to sacking aprons, from knitted panties to topsy-turvy dolls, they provide a unique insight into women's art and creativity in a new country learning its own nature. Superbly illustrated with hundreds of examples from the 30s, 40s and 50s and designed by Sarah Maxey, this book is destined to become a classic.
