EVALUATION OF NON-CHEMICAL ALTERNATIVES TO ENDOSULFAN
FAO promotes a new paradigm of sustainable crop production intensification (SCPI) that conserves and enhances natural resources. It uses an ecosystem approach in which inputs of land, water, seed and fertiliser compliment natural processes that support plant growth, pollination, natural predation for pest control, and soil biota to enhance plant access to nutrients. It draws first and foremost on nature’s contribution to crop growth, and applies appropriate external inputs “at the right time, in the right amount”. (...) The aim is not one of total eradication, which undermines the viability of populations of natural enemies, but one of balance and minimised crop losses.

Jute, abaca, coir, kenaf and sisal (JACKS) are natural fibres that have multiple end uses. Their versatility and the increasing awareness of their environmentally friendly characteristics are strong advantages over synthetic fibres. (...) Demand for these fibres is strong due to their variety of applications including cordage, geotextiles, carpets, buffing cloth, specialty paper, binding material, “soft” applications in the automotive industry, and the increasing awareness that natural fibres are environmentally friendly. The JACKS market is stimulated by the increasing demand for value added products, and further growth is expected on the back of diversification and improved policies. (...) Coir Geotextiles made from coir are durable, absorb water, resist sunlight, facilitate seed germination, and are 100 percent biodegradable.

GUIDELINES FOR ERGONOMIC WORKSTATIONS AND WORK WITH COMPUTERS / FROM THE ASSISTANT SECRETARY-GENERAL FOR HUMAN RESOURCES MANAGEMENT
If special work tasks require desk lights, they may be provided, taking into consideration the nature of the work, available desk space and safe and reliable wiring. (...) The windows should be covered with drapes or blinds to prevent direct sunlight. The walls should be dark or pastel colours, with the matte finish less than 50 per cent reflective. (...) To rest the eyes, electromagnetic fields often referred to as “radiation”. turn them away from the screen and look at something at least Electromagnetic fields also occur naturally, for example, by 25–30 feet away, blink several times, or close the eyes and the magnetic field of the Earth, cosmic rays and sunlight. relax.

Challenges of daylighting • Glare is experienced when direct sunlight penetrates into buildings and reflects off surfaces, causing visual discomfort. (...) Daylight availability The source of daylight is the sun and it may reach the building in the following ways as illustrated by Figure 01. • Direct sunlight along a straight path from the sun, through an opening to a given point; • Diffuse light through the sky and clouds; • Reflected light – either externally by the ground and surrounding buildings or internally by walls, ceilings and other internal surfaces These factors determine the illuminance level at any point in the room.

ACTION BY THE DGP-WG 2.1 The DGP-WG is invited to: a) revise the wording of Special Provision A20 as follows: A20 During the course of transport this substance must should be protected from direct sunlight and all sources of heat and be placed in an adequately ventilated area. (...) In addition the radioactive material, excepted package label would become Figure 5-29 and the lithium battery handling label would become Figure 5-30. d) revise the provisions of Part 5;4 to delete paragraph 4.1.5.8.3 that currently requires that a statement must be added to the dangerous goods transport document with an indication that self-reactive substances or organic peroxides being offered for transport must be protected from sunlight and sources of heat. 4.1.5.8.3 When self-reactive substances of Division 4.1, or organic peroxides of Division 5.2 or other substances having similar properties, are offered for transport, the shipper must indicate on the dangerous goods transport document that the packages containing such substances must be protected from direct sunlight and all sources of heat and be placed in adequately-ventilated areas. e) revise the provisions of Part 7;2.13 to remove the mandatory requirement for operators to ensure that packages or ULDs containing self-reactive substances or organic peroxides be protected from sunlight and sources of heat during the course of transport. It’s proposed that this be a recommendation only, as follows: 2.13 HANDLING OF SELF-REACTIVE SUBSTANCES AND ORGANIC PEROXIDES During the course of transport, packages or unit load devices containing self-reactive substances of Division 4.1 or organic peroxides of Division 5.2 must should be shaded from direct sunlight, stored away from all sources of heat in a well-ventilated area. — END — << /ASCII85EncodePages false /AllowTransparency false /AutoPositionEPSFiles true /AutoRotatePages /All /Binding /Left /CalGrayProfile (Dot Gain 20%) /CalRGBProfile (sRGB IEC61966-2.1) /CalCMYKProfile (U.S.
