On their second record, the Columbus, Ohio quartet play away the pain.
There’s a fine line between growing weary of the world and giving up on it. The latter marks a political and emotional dead end, but the former can open the door to constructive thought. Growing tired of something grants space for dreaming up its replacement. In the ’90s, guitar bands like Dinosaur Jr. and Sonic Youth managed to funnel their weariness into restive stews of noise that approached political quandaries from an oblique angle. When Kim Gordon asked, on “Kool Thing,” “Are you gonna liberate us girls from male white corporate oppression?,” she already knew the reply. It’s the asking that counts, even if you’re already sick of the answer.
Following this sly template, the Columbus, Ohio band didi eschew the blunt force of punk, investing their political frustrations instead in the more subtle vessel of melody-rich noise pop. Their second album, Like Memory Foam, darts in and out of the personal and political. Breakup songs mingle with calls for the obliteration of the old guard, and didi treat both subjects with the same swirling mix of gravitas and irreverence. Interpersonal frustrations and political oppressions both cause suffering, after all; the body buckles in the same way no matter the source of the pain.

China Introduces Mandatory Standard for Synthetic Sports Surfaces Used in Schools
- (1888PressRelease) November 30, 2018 – China has introduced a mandatory standard for synthetic surfaces used in school sports venues. Since November 1, 2018, the standard – GB 36246-2018 – has been compulsory for all synthetic sports surfaces used in primary and secondary schools.
Initially published in May 2018, GB 36246-2018 ‘Sports areas with synthetic surfaces for primary and middle schools’ replaces the recommended but voluntary standard GB/T 19851.11-2005 ‘Sports equipment and playground for middle school and primary school Part 11: Synthetic surfaced athletic ground’.
The standard applies to new, renovated and expanded outdoor sports venues containing synthetic surfaces for competition, training, teaching and other activities in primary and secondary schools. It defines specific requirements and includes requirements related to design, installation, physical and mechanical properties, aging resistance, hazardous substances, and odor in synthetic materials, finished products and raw materials. It also covers sampling requirements, rules for inspection and standard methods.
Limits for hazardous substances include:
• DBP, BBP and DEHP: ≤1.0 g/kg (sum of 3 phthalates)
• DNOP, DINP and DIDP: ≤1.0 g/kg (sum of 3 phthalates)
• 18 Polycyclic aromatic hydrocarbons (PAHs):
o ≤ 50 mg/kg (sum of 18 PAHs)
o ≤ 20 mg/kg for the top 5 mm of the surface material (sum of 18 PAHs)
• Benzo [a] pyrene: ≤ 1.0 mg/kg
• Short chain chlorinated paraffins (C10-C13): ≤ 1.5 g/kg
• 3,3′-Dichloro-4,4′-diaminodiphenylmethane (MOCA): ≤1.0 g/kg
• Free toluene diisocyanate (TDI) and free hexamethylene diisocyanate (HDI): ≤ 0.2 g/kg (sum of TDI and HDI)
• Free diphenylmethane diisocyanate (MDI): ≤ 1.0 g/kg
• Soluble lead: ≤ 50 mg/kg
• Soluble cadmium: ≤ 10 mg/kg
• Soluble chromium: ≤ 10 mg/kg
• Soluble mercury: ≤ 2 mg/kgThe limits for hazardous substance emissions are:
• Total volatile organic compounds (TVOC): ≤ 5.0 mg/m²h
• Formaldehyde: ≤ 0.4 mg/m²h
• Benzene: ≤ 0.1 mg/m²h
• Toluene, xylene and ethylbenzene: ≤ 1.0 mg/m²h (sum of 3 solvents)
• Carbon disulfide: ≤ 7.0 mg/m²hFinally, the odor level must be below or equal to 3.
