Household composition

Living standards measurement surveys (or multitopic household surveys). Multisubject, integrated surveys that gather data on a number of aspects of living standards to inform policy. The surveys cover spending, household composition, education, health, employment, fertility, nutrition, savings, agricultural activities, and other sources of income. 

Textiles are among the most ubiquitous materials ia society. They provide shelter and protection from the environment ia the form of apparel, as weU as comfort and decoration ia the form of household textiles such as sheets, upholstery, carpeting, drapery, and wall coveting, and they serve a variety of iadustrial functions, eg, as tire reinforcement, tenting, filter media, conveyor belts, iasulation, and reinforcement media ia various composite materials. 

Antistatic compositions are being sold for appHcation during household laundering to be added in the rinse cycle or during tumble drying. Most of... 

Phenohc resins (qv), once a popular matrix material for composite materials, have in recent years been superseded by polyesters and epoxies. Nevertheless, phenohc resins stiU find considerable use in appHcations where high temperature stabiHty and fire resistance are of paramount importance. Typical examples of the use of phenoHc resins in the marine industry include internal bulkheads, decks, and certain finishings. The curing process involves significant production of water, often resulting in the formation of voids within the volume of the material. Further, the fact that phenoHcs are prone to absorb water in humid or aqueous conditions somewhat limits their widespread appHcation. PhenoHc resins are also used as the adhesive in plywood, and phenohc molding compounds have wide use in household appliances and in the automotive, aerospace, and electrical industries (12). 

Detergent compositions also vary from country to country. The world market for household detergents can be divided into four segments according to the physicochemical properties of the wash solutions prepared from the detergents. 

The I I cleaning procedures as a whole, compared with household laundering, are characterized by huge variations in the composition of the soils, types of surface to which they adhere, cleaning time available, etc. The optimum choice of enzyme type and dosage level normally has to be established through a cooperation between the customer (end user), manufacturer of the detergent, and enzyme producer. 

The information presented in this chapter is intended to provide a brief overview of the composition, performance, and formulation properties of LAS by itself and in combination with other surfactants. The particular performance synergies and processing characteristics of certain combinations of surfactants are discussed briefly. The examples of mixed active formulations provided herein represent to the best of the author s knowledge the approximate levels of major surfactants in actual household detergent products both past and present. This does not imply that these formulations are complete because many additives, such as bleaches, enzymes, builders, hydrotropes, thickeners, perfumes, and coloring agents, may also be present in varying amounts. 

Samples were taken from MSW in district Hai Ba Trung, Hanoi. Waste sources are mainly from households and small street restaurants without separation at source. In this district, waste composition contains high percentage of biowaste which accounts for 55-69%, and plastic and nylon bag are 4-5% and 1.5-2%, respectively [11, 12]. 

The penetration of thermoplastics and thermoplastic composites ranges from the totality of the considered parts - for example, small household appliance housings and casings where metals are nearly ousted - down to areas where there are only a few applications, such as highly conductive polymers. 

A number of environmental applications [3] have been performed in order to size characterize colloids collected in rivers (riverbome particles, SPM, and sediments), clay samples and ground limestone (from soils), coal particles, diesel soot particles (from combustion processes), or airborne particles in urban areas (from waste incinerators, vehicles, household-heating systems, and manufacturing). In many of these cases, not only the size but also the particle size distribution was important and thus, in conjunction with the traditional UV detector, specific detectors such as ETAAS, ICP-MS, ICP-AES were used [40] in order to obtain more detailed, more specific compositional information. 

The answer is C. The patient s symptoms represent a composite of neurologic and gastrointestinal dysfunction, which are consistent with the anemia that is due to lead poisoning. Testing for lead would be appropriate for the patient, the other members of the household, and the house itself. Inorganic lead produces the microcytic anemia by inhibition of heme synthesis in erythropoietic cells of the bone marrow. All the other options represent enzymes of heme synthesis or degradation, but none of them are affected by lead.
