A ballast water treatment device attached to a vessel provided with: a line (1) through which drawn treatment target water flows; and a ballast tank (5) connected to a downstream side of the line (1). The ballast water treatment device is provided with: a filter (3) which is disposed in the line (1) and which filters the treatment target water; and a controller (7). The controller (7) causes the treatment target water to be discharged outboard from an upstream side of the filter (3) in an early stage of drawing of the treatment target water, until water quality is stabilized, and, when the water quality of treatment target water has stabilized, causes the filter (3) to filter the treatment target water. Thus, ballast water filtering can be efficiently performed.

While the region's influence on mainstream hip-hop has gone overlooked for decades, a new generation of break-out artists are reclaiming their musical heritage and drawing national attention back to the area. In the hours leading up to their showcase at The Chapel in San Francisco's Mission District in late February, members of HBK Gang milled about the overcrowded green room, laughing, dancing, and taking selfies. The effervescent supergroup consists of more than a dozen East Bay rappers, singers, and producers mostly in their early twenties.…

The Bay Area Vibez festival landed at the Port of Oakland this past weekend, bringing world-renowned reggae, electronic, and hip-hop artists to Middle Harbor Shoreline Park — a vast, open space that overlooks the San Francisco skyline. In its first year, the event arrived with a seemingly enormous budget and star-studded lineup that included living legends Stephen Marley, Damian Marley, and Nas.

But despite the festival’s grandiosity, the event ultimately felt like a way to capitalize on people’s nostalgia for bygone eras, prioritizing artists who haven’t released new material in years or are descendants of celebrated musicians.…

Roughly fifty demonstrators marched from Fruitvale BART on Friday night to Oakland City Hall in an anti-police rally called in response to the fatal shooting of Richard Perkins by Oakland police on November 15. But unlike protests earlier this year, police didn’t try to drive demonstrators onto the sidewalks to comply with Oakland Mayor Libby Schaaf’s policy banning nighttime street marches.…

'Don’t build technology for Mordor.' On Saturday at Peter Thiel’s San Francisco home overlooking the Bay, protesters demonstrated against a collaboration between Immigration and Customs Enforcement and Palantir Technologies, a data-mining firm that Thiel co-founded. As reported in The Intercept, ICE will be using a new Palantir product called Investigative Case Management to to aid in its expanded deportation mission.…

Including a photo slideshow. Even at 10 a.m. this past Saturday morning, hours before a throng of anti-fascists and Trump-supporting white nationalists overtook downtown Berkeley’s streets, it was clear that most of the attendees were less interested in speeches, protesting, and free speech — and were mostly there just to tee-off on each other. Before the brawling began, officers stationed themselves at the entrances to downtown's "Peace Park."…

Turf dancing has become ubiquitous on the trains, providing steady income, a creative platform, and a built-in audience. On a recent Friday, Yaameen Muhammad stood on the West Oakland BART platform, the afternoon sun reflecting off his neon-yellow high-tops.…

The last time J Balvin was at Oracle arena was back on Feb. 15, 2015 when he was the opening act for Pitbull and Enrique Iglesias' joint tour. I was at that show with my mom as my date, and vividly remember her saying, “one day he’s going to headline his own tour here.” I brushed off her comment, it wasn’t that I didn’t believe that he was talented.…

Wiltshire becomes a metaphor for today's Britain in Barney Norris' retelling of Lorca's Blood Wedding at Salisbury Playhouse. The blood feud of the original is replaced by laddish drunkenness and Mediterranean passion by English reticence in which ‘Sorry’ is the most used word.

News this week that fed-up residents in a Southampton street are threatening to blockade their own thoroughfare on the grounds that they have problems with poorly-parked vehicles, would seem to be a case of nose cutting to spite faces.

LIKE many drivers in Southampton, I will be delighted when the long-running roadworks near the Red Funnel ferry terminal at Town Quay finally comes to an end.

THERE’S no doubt that the Prime Minister spoke from the heart when he addressed the Tory conference in Birmingham this week, speaking of the NHS.

It is interesting that the Greek Prime Minister, Alexis Tsipras, summons the very real fact his nation invented democracy to bolster his government’s argument for a favourable solution to the debt crisis wracking its citizens.
