Concrete Technology
Pump: Innovative and reliable
With high delivery pressures of up to 130 bar for delivery outputs of up to 160 m³/h, Putzmeister pumps are suitable for all concreting tasks.
The S-transfer tube is the optimum leak-proof delivery system as there is only one point of separation between the spectacle plate and the transfer tube. The entire switch-over hydraulics and bearings lie outside the concreting area. The low number of parts and ease of exchange make them extremely maintenance friendly. Additionally, the hopper does not have to be dismounted to exchange the wear parts.
Specific details such as the durable delivery pistons, series standard chrome-plated delivery cylinders and the S-transfer tube system designed by Putzmeister ensure that all our machines are able to withstand long periods of intensive use.
Mode of operation
- The low lying agitator which is driven at both ends shifts the concrete directly in front of the cylinder openings.
- Two powerful and quick moving switch cylinders (which are muffled) move the trunk back and forth in front of the large suction openings, thus releasing the pressure and intake openings alternately.
- Depending on the position of the S-valve the concrete is lighting into a cylinder or pressed through the delivery pipeline.
Piston Pump (S valve system)
Stationary concrete pumps with the S-transfer tube are continually setting new world records in vertical and horizontal delivery. For example, in 1994 at Riva del Garda in Italy, concrete was pumped vertically over 532m! Or a pump height of 606m at the Burj Khalifa job site in Dubai. Even in these cases, both the machines and accessories were not operating at their limits. Even when dealing with difficult concrete Putzmeister machines can be counted on to perform continiously and reliably.
Wherever extremely stiff and highly abrasive mixes are encountered this system is used. Of course it is also available with truck-mounted concrete pumps. In pre-cast factories you will find always find a piston pump when it comes to high strength concrete, steel fibre concrete or when there is a longer distance to cover.
The S-valve is the first choice for concrete pressures above 85 bars. This is especially useful for long pumping distances over stationary pipelines. The Putzmeister S-valve is especially designed for long life and high concrete pressure. This results in long service intervals and increased availability of the machine. To extend the life of the S-valve, the inside wall can be rebuilt by hard face welding.
Rotor Pump
Mode of operation
One of the greatest strengths of this pump with Ergonic® system is the computer assisted control that ensures the machine operates extremely quietly and runs smoothly at a constant speed. Other key characteristics include the extremely low wear of the pump components and minimal concrete residue. More precisely, the rotor hose is the only wear part on the pump and can be replaced very quickly and easily. The rotor pump can convey materials that are less suitable for a piston pump (e.g. lightweigt concrete, screed and steel fibre concrete,Self compacted concrete SCC, liquid concrete, broken material, air-entrained concrete). The durability and simplicity of the rotor pump can be attributed to the efficient agitator. The material is being filled in the hopper and then drawn through the feeder cone into the rotor. This prevents the concrete from setting, even after a longer pump break.
Since only the hopper and the rotor hose comes into direct contact with the material, both the hose and the delivery line can be cleaned thoroughly with a sponge ball in a very short time, consuming only a small amount of water. If the hopper has a sloping base, water and concrete residues collect on the hopper flap. Nearly 100% of the concrete in the hopper can be delivered to the construction site, i.e. no more concrete residue and detours, expensive concrete residue disposal can also be avoided.

Free-flow hydraulics
Benefits at a glance
- More power and less energy lost
- High efficiency
- While valves interrupt the oil flow on other systems, the intelligent control directs the oil into the drive cylinders without significant losses
- Expensive control blocks are not required which avoids the oil heating up and makes servicing easier
- Powerful and convenient operation
Today concrete pumps are predominantly operated by hydraulic systems. Putzmeister places its trust in the benefits of free-flow hydraulics because the most important performance factors are the concrete pressure, low-loss oil delivery and costs.
When large quantities of concrete are pumped, large quantities of oil also flow inside the hydraulic system. More power is transferred inside a closed free-flow hydraulic circuit because the oil is conveyed from the pump to the drive cylinders without loss. The adapted hydraulic System ensures extremely powerful interaction between components. Compared to the open circuit, this ingenious drive technology requires significantly less oil and does not generate as much heat. The system is also economical to operate because it achieves a high degree of energy efficiency and is easy to service.
Greater efficiency, lower costs, increased flexibility – these are the results that Putzmeister truck mounted and stationary concrete pumps with Ergonic® systems can achieve in practice.

Politics issue out!
I've never felt disillusioned by the role or the intent of the Canadian government. That's because I've never believed it works in my best interests, or in the best interests of most people I know. Still, from the time I turned 18, I did my best to make it work: I voted. I worked for a major political party. And I even came a breath away from running for one myself (note: never share empanadas and dissent with a party organizer).
But those were acts of desperation. I've known for a very long time now that I live and work on stolen land. I know that our country exists because of the genocide of Indigenous Peoples, that Canada continues to exist because of ongoing colonization. I know the ways in which government fails Indigenous Peoples and continues to create huge disparities among settler populations along lines of race, gender, sexuality, (dis)ability, status and class. My acts of political engagement within the system come from a belief that I can be empowered to make a change, and that any change has got to be an improvement on what we've got.
For those of us who engage with party politics, this past year has been particularly exhausting. Shameless HQ is in Toronto, and 2010-11 brought us three disappointing elections. Now, in the name of austerity, we face threats to social services, the arts and economic and food security – things that make up the social fabric of a society. It hurts.
When things get this bad, I am especially grateful for other kinds of political engagement. I came into my current life via community organizing, crisis counselling and by exploring the intersection between art and radical politics. I am grateful for community: for groups like the Toronto Rape Crisis Centre/Multi-cultural Women Against Rape, who have organized 31 years of Take Back the Night, for those who took to the streets during the G20 in Toronto last year, and for those who identify with the 99% and continue to resist as I write this. I am also grateful for Shameless.
Shameless has become a community to me: a community within itself, and a community that extends beyond the amorphous walls of "Shameless HQ." When Jack Layton passed away and I needed someone to talk to, there was a Shameless editor equipped with sushi and insight there for me. When the experience of reading Feminism for Real totally rocked my understanding of what it means to identify as a feminist, there was a group of editors, writers and bloggers around to take that journey with me (stay tuned for our very first Shameless Book Club podcast). And, when we as an editorial staff struggled with the enormity of putting out a "politics" issue, there was Erin Konsmo (Metis/Cree Indigenous feminist artist and change maker), who provided invaluable support and guidance that saw this process through. I am grateful for Shameless because this community provides us with ways of moving beyond desperate acts of political engagement and empowers ourselves to produce the kind of media that we want in an effort to create the kind of world that we want.
As a reader, you are a part of this community, too. The most basic building block of dissent is dialogue, and we hope to promote that with every issue. As you flip through the pages, read about Indigenous Sovereignty (p. 18), question the system that we've got (p. 23) and challenge what Canada is doing abroad (p. 29, and check out the feature online here). When you're done, I invite you to join the community that's become so important to me: write to us, continue the conversation and empower us to produce the kind of media you want, to create the kind of world that you want.
Yours shamelessly, sheila firstname.lastname@example.com

Hi Marvin,
I've installed your Kodi on my Pi4, working great, I've tried to stress it by playing 4K HEVC (h265) & it didn't even work up a sweat, about 10% CPU usage, processor not getting above 60C.
Thank you for providing this build, with any luck someone will put it in the official repository, so anyone can install it. Also, as always, thanks to everyone who contributes to the Kodi project, especially Dom/Popcornmix for their Pi related input.
Regards Kevin.
Share & Enjoy.

Row-Level Security
This page is for discussing the implementation of Row-Level Security (RLS) in PostgreSQL. You can find the current progress of this proposal at the commitfest page.
RLS is a security feature which allows users to give access to a sub-set of data in their table to others. Traditional RDBMS permission systems don't distinguish the individual rows in a table- GRANT SELECT on a table will allow a user to access all rows of that table. With RLS, requirements such as "a manager can only view sensetive employee information for those employees who report to them." can be specified and enforced by the database.
Jobs of access control feature
According to the definition of ISO/IEC27001 (information security management), design target of information security feature is to ensure confidentiality, integrity and availability of information asset. In short, these are often called C.I.A. Access control contributes towards both confidentiality and integrity. Access controls prevent unprivileged users from reading or writing information asset base on the rules which are configured in the access control system. Information or data itself does not have a particularly tangible form and therefore it must be stored in an object. Usually, access control features allow or prohibit users access to the object that contains the information or data. The intent of this feature (RLS) is to allow a more fine-grained control over the information inside of the objects. For example, regular GRANT/REVOKE mechanisms control access on the specified database object according to the access control list, but they do not allow anything more granular.
Design Target
The purpose of row-level security feature is to prevent users (not means database roles, just users) from accessing unprivileged rows. Please note that "access" means two different direction of information (1) data read (rows => users) for confidentiality, and (2) data write (users => rows) for data integrity. Due to the nature of database access, it is the most straight-forwards way to describe the rule with regular qualifier style of WHERE clause; that is an expression returning a boolean value.
Overall, RLS prevents users from reading and writing rows that do not satisfy the rule (also know as a row-security policy). If we support per-command configuration, the row-security policy to be checked depends on the command. RLS design accepts individual row-security policy to be applied on SELECT, INSERT, UPDATE or DELETE. Relevant discussions are below.
We have some SQL commands that allow users to access database rows; SELECT, INSERT, UPDATE or DELETE. COPY TO/FROM is synonym of SELECT and INSERT from security perspective. In case of SELECT (data read), what we should do is quite simple: any rows that don't match with the configured row-security policy shall be filtered out for unprivileged users. In case of INSERT or UPDATE (data write), RLS prevents unprivileged rows from being written to the table, as if CHECK constraint performing. In case of UPDATE or DELETE (data write), RLS prevents unprivileged rows from appearing as candidates of modification; that means row-security policy should be applied on the table scan stage. We also need to pay attention on potential information leaks using the leaky-view scenario below. So, UPDATE and DELETE shall also take row-security checks of SELECT command on table scanning stage.
TRUNCATE command performs as if DELETE, but much faster. It has its own permission separated from DELETE. So, we re-define meaning of TRUNCATE permission; that also implies to ignore row-security policy of DELETE.
Row-security policy is set by table owner, using the following syntax. If no "ON <command>" given, a unique security policy shall be applied on all the supported privileges (SELECT, INSERT, UPDATE and DELETE).
For example, an UPDATE command requires SELECT privilege to read a row, yet UPDATE privilege to change a row.
ALTER TABLE <relname> SET ROW SECURITY FOR <privilege> TO (<expression>); ALTER TABLE <relname> RESET ROW SECURITY FOR <privilege>;
<privilege> can be one of: ALL, SELECT, INSERT, UPDATE, DELETE. The initial implementation may only support 'ALL'.
'ALL' would simply define the same policy for all the commands. Later commands which update only a single command would replace the policy for that command only, leaving the policy for the other commands to what was set from the initial 'ALL'. The same goes for a RESET. Listing the policies in a table form would look like:
ALTER TABLE mytable SET ROW SECURITY FOR ALL TO (where user = 1);
|user = 1
|user = 1
|user = 1
|user = 1
If it was followed by:
ALTER TABLE mytable SET ROW SECURITY FOR SELECT TO (where user = 2); the result would be:
|user = 2
|user = 1
|user = 1
|user = 1
and so on. If no row security policy has been set for a given command type (or the security policy has been reset for that command type), no row-level security would apply and regular GRANT permissions for the operation would be used. Note that row-level security does not override existing GRANT permissions but provide a more fine-grained control. For example, setting 'ROW SECURITY FOR SELECT' to allow a given user to give rows would only give that user access if the user ALSO has 'SELECT' privileges on the column or table in question.
Superuser bypass row-security policy (1) to avoid Trojan-horse attack by table owner (2) to ensure consistent view for database backup, however, row-security policy injected by extension (such as sepgsql) is exception.
Issues & discussion
Per-command security policy
Asymmetric row-security policy may cause unexpected information leaks using UPDATE or DELETE command with RETURNING clause or leaky functions in WHERE clause. It is an idea to append row-security policy of SELECT when executor scan the result relation. It ensures the rows to be modified are also visible to the user executing the UPDATE. One other idea was to enforce a unique policy for all commands, however, it has a problematic scenario when user wants to define INSERT-only relation.
Writer-side checks
Now we can implement writer-side checks on INSERT or UPDATE command using before-row triggers. On the other hand, it makes users to synchronize the configuration of RLS with triggers of this checks. One model case to solve this concern is implementation of FK constraints; that automatically defines before-row triggers that checks newer version of tuples to be inserted or updated.
Table statistics
pg_statistic hold some example of values on the table being analyzed. Right now, we have no way to prevent users to see collected values on statistical board. An idea is to mask the field if the relation has RLS policy.
Minimal core feature set
- Checks are only applied on table scanning. If writer-side checks are required, users can do that using triggers, even though it takes complex setting.
- A unique security policy can be configurable on a table. Even though RLS design allows per-command policy, we need to investigate whether asymmetric policy is harmless.
Previous discussion in 2010
- Before we can try to tackle row-level security generally, using labels or not, we need to fix the issues with data leaks in views.
- Related topics in -hackers
Issue: A leaky VIEWs for RLS
- This issue is summarized as: an untrusted user can define a function which stores all information it is presented, then query a view using that function in a way which will convince the planner to send every row of the underlying table to the function, thus leaking data in the table which the view was intended to prevent.
In this message, KaiGai pointed out we have two different causes of the problem, but both of them can cause same information leaks.
- [1] Unexpected order to evaluate qualifiers on a certain scan plan
- When a scan-plan has multiple qualifiers to filter scanned tuples, the optimizer sort the qualifiers based on their estimated cost to execute. If an exogenetic function has smaller cost than other qualifiers come from view definition, the exogenetic function shall be evaluated earlier than others, then contents of invisible tuples may be provided to malicious user-defined functions.
- It is reordered at order_qual_clauses().
- [2] Unexpected qualifier distributions into inside of join loop
- When planner makes a scan plan, it tries to distribute qualifiers of scans into smaller unit as possible as it can. For example, if a function takes arguments only come from a certain table, it will be distributed into scan plan of the table, not outside of the join.
- When a view contains JOIN clause between A and B, user can reference the view with his own WHERE clause. If a clause takes arguments depending on only A, the planner distribute the clause into the scan plan of A. In the reault, tuples to be filtered out may become visible to user defined functions.
- It is distributed at distribute_qual_to_rels().
- At the point [2], if we prevent all exogenetic functions to push down into join loops, it will make unignorable performance degradation, although the view might not be intended to security purpose.
- It needs a way to provide a hint whether the view is defined for security purpose, or not.
- Tom Lane suggested CREATE SECURITY VIEW AS ... statement.
- It was not concluded which is the default. Security view? Regular view?
- How about a GUC option to specify the default? NACKed.
- In addition, Robert Haas suggested to test privileges of users whether they have privileges to reference underlaying tables without vires, or not. If available, it is eventually harmless even if user defined functions are evaluated within join loop.
- Here was one opposition because this check will be applied on planner stage, not execution stage.
- KaiGai submitted a proof of concept patch that prevents to push down exogenetic functions into security views.
- At the point [1], we don't have any active discussions yet.

Components of an implementation
- Overview
- Allow the query to be modified, prior to being passed to the planner, in such a way that the rows returned will be those the user is authorized for
- This depends on being able to tell the planner that this filter must be done, in some way, prior to user-defined functions being called
- This issue is related to the VIEW leak described above. Once that issue has been resolved, this should be pretty straight-forward to implement
- Grammar for catalog updates/changes; user-interface for specifying how RLS is to be done
- Catalog changes for storing RLS information
- Storage - Could this just be a regular column in the table? It would be good to avoid changing the header or creating a system column for this.
- We would need to track, in some fashion, the "security" column in the catalog, perhaps as a flag on pg_attribute, or a 'security_attnum' in pg_class, etc.
- Planner updates to enforce the filter based on RLS- this can't be done till after we deal with the issue with VIEWs
- Executor changes may not be required.. but how to deal with stored plans? Use invalidation if anything changes with regard to RLS?
- Other?
- Covert Channel
- If we try to insert a value which violates a PK constraint, we can assume existence of invisible PK from the error.
- The same issue exists in a Foreign Key relationship situation
- Other databases with row-level security don't address this issue, so it's unclear if we really need to (reference?)
- In any case, this isn't something we need to address in our initial RLS implementation
- Order to evaluate row level policy
- Addressed above with regard to views, once we solve that, this will be handled
- TRUNCATE statement
- TRUNCATE is expected to be fast.
- If the user does not have rights to remove all rows from the table regardless of row-level policy, then any TRUNCATE must be denied.
- Turning TRUNCATE (a PostgreSQL extension which is not in the SQL spec anyway) into a DELETE FROM doesn't make sense.
- COPY TO statement
- COPY can just be reformed into a COPY statement with a query being used instead, eg:
- COPY tblname TO xxx; can be replaced by COPY (SELECT * FROM tblname) TO xxx;.
- Table inheritance
- Not something we really need to deal with in the initial version, so long as it doesn't completely break (or we make sure it does for inheritance)
- What policy should be applied on the parent and child relations.
- idea: Also copy row-level policies from the parent tables.
- Foreign Key constraint
- Adding multiple modes for FK should be a separate, follow-on patch, it doesn't need to be in the initial version.
- idea: We can provide two modes: The first is filter-mode, the second is abort-mode.
- filter-mode: A normal mode. Row-level policy is evaluated earlier than user given condition, and returns false, if violated.
- abort-mode: A special internal mode. Row-level policy is evaluated after all the condition, and raises an error, if violated. The condition shall be evaluated earlier than row-level policy, the query has to be trusted. Such as queries in FK constraint.
- Performance
- With RLS
- Without RLS
- The page.16 of LAPP/SELinux slides shows a pgbench comparison between pgsql-8.4.1 vs SE-PostgreSQL with RLS.
- It has 2-4% of performance tradeoff depending on database size.
- Note that SE-PostgreSQL implemented RLS in a different way than what is being proposed here; our goal is to get RLS support into core PG
- Integration with external security manager (eg: SELinux, SMACK)
- This will not be included in the initial support of RLS (unless we happen to get support for external security managers implemented first in PG)

CDOT warns of heavy Monday traffic
Vail, CO Colorado
VAIL – Some holiday weekend drivers might have a few tricks up their sleeves for beating the holiday traffic, but the fact remains that Interstate 70 is likely to be jammed heading eastbound Monday.
The Colorado Department of Transportation offers some advice for holiday weekend warriors: Leave before 11 a.m. or after 5 p.m. to avoid the most congestion along the interstate.
One of the heaviest weekend traffic volumes was Friday between 3 p.m. and 8 p.m. on westbound I-70. That traffic will be heading in the other direction Monday, as eastbound I-70 is expected to get crowded between 11 a.m. and 5 p.m., with CDOT expecting delays of up to one hour.
Stop-and-go traffic continued Saturday, however, with CDOT reporting heavy westbound traffic between Mount Vernon Canyon and Empire, milemarkers 256 to 232. Speeds were ranging between 20 and 40 miles per hour through the area Saturday early afternoon.
Mindy Pannell reported on the Vail Daily's Facebook page that traffic on I-70 was "horrible" Saturday morning.
Vince Talavera Tommasi chose to stay in Denver this weekend for that very
"Monday morning will be a complete horror show on eastbound I-70," Tommasi wrote on Facebook.
CDOT spokeswoman Stacey Stegman said construction and maintenance projects on highways this holiday weekend will be limited to projects that won't affect traffic. She said there shouldn't be any lane closures due to construction.
Stegman expects the number of cars on I-70 to increase from last year. She said the department has been looking at economic conditions that show people are starting to have more discretionary income, which should lead to more travel. Also, Stegman said Colorado's gas prices haven't seen large spikes like in other states, which should also contribute to more holiday weekend travel.
So how do you beat the traffic?
"Stay until Tuesday," said Chris Romer, the Vail Valley Partnership executive director.
Others offered similar advice on the Vail Daily's Facebook page.
"Don't drive on Monday," Rae Jensan said. "Simple."
Blair Kjorvestad thinks a steady speed could solve some of the problem "instead of braking uphill like I always see people doing."
AAA Colorado expects 553,000 Colorado residents to travel during Labor Day weekend, a 3.2 percent increase over last year. This year's spike, if predictions are accurate, would mark the third consecutive increase in Colorado holiday travel this year after a 1.4 percent increase over Memorial Day weekend and a 4.8 percent increase for July 4th travel.
AAA Colorado attributes the spikes to improving consumer confidence compared to a year ago "and American's unwavering desire to travel."
The average price of regular gas in Colorado is currently $3.53 per gallon, while the national average is $3.80.

Why visit Maine?
Bigelow is considered the second best hike in Maine after Katahdin, because of its size, challenge and beauty. The reasons can be read as a list of hiking buckets: emerald ridges, deep passes (low point between two peaks) and long two-day climbs (bring the tent). It takes 16.3 miles to climb and cross Bigelow, but if you just want to reach Avery Peak (4,088 feet), the trek is shorter - if not less difficult - 7.8 miles. Many people camp at Avery, which has tent platforms, to better enjoy the amazing views from the top of Lake Flagstaff and the mountains of western Maine.
The best family hikes in Maine are those with swimming holes where you can play. If you agree, head to Blueberry Ledges in Baxter State Park for a long hike with a waterfall in Maine. Here, Katahdin Creek flows over granitic rocks to create natural water slides. Blueberry Ledges is one of the favourite places for people staying at Abol Bridge Campground and exploring Baxter National Park. Well named because of the wild blueberries growing along the trail, this trail is an excellent trail to follow from early to mid-August for the blueberry season. If you will be there with your family at this time of day, I recommend that you get a copy of the book Blueberries for Sal that you can read to your children to extend your trip in a fun way.

The Purity of Vengeance: A Department Q Novel
November 1985
The feeling could get the better of her in an unguarded moment. The cool, delicate champagne glass between her fingers, the hum of voices, and the light hand of her husband at her waist. Apart from being in love, only brief flashbacks of a distant childhood reminded her of it. The security of her grandmother's chatter. Subdued laughter as she fell into a slumber. The laughter of people long since gone.
Nete pressed her lips together to stem the emotion. Sometimes it got the better of her.
She collected herself and gazed out upon the palette of colorful evening gowns and proud figures. The celebratory banquet in honor of the Danish recipient of the year's Nordic Prize for Medicine had drawn many guests. Scholars, physicians, pillars of society. Circles into which she certainly hadn't been born but in which she nevertheless had come to feel increasingly comfortable as the years passed.
She took a deep breath and was about to let out a contented sigh when she became acutely aware that a pair of eyes had latched onto her through the array of festive coiffures and men in tight bow ties. The inexplicable, unsettling charges of electricity only ever emitted by eyes that wished no good. Instinctively she moved aside, like a hunted animal seeking cover in undergrowth. She put her hand on her husband's arm and tried to smile as her gaze flickered across the shimmer guests and the elegantly dressed of the candelabra.
A woman tossed back her head in a moment's laughter, suddenly opening up a clear view to the rear end of the hall.
And there he stood.
His figure towered like a lighthouse above all the others. Despite the stooping posture and crooked legs, a great, strutting wild animal whose eyes swept over the crowd like a pair of searchlights.
Again she sensed his intense surveillance to the very core of her being and knew for certain that if she didn't react now her entire life would collapse in seconds.
"Andreas," she said, putting her hand to her throat, which was already sticky with perspiration. "Can't we leave now? I'm not feeling well."
Further entreaty was unnecessary. Her husband raised his dark eyebrows, nodded to those nearest, and turned away from the throng, taking her arm in his. It was typical of him, and she loved him for it.
"Thank you," she said. "I'm afraid it's my headache again."
He nodded, all too familiar with the affliction himself. Long, dark evenings in the drawing room, his migraine pounding.
It was yet another thing they had in common.
As they approached the majestic staircase the tall man stole forward and stepped in front of them.
He looked much older now, she noted. The eyes that once had sparkled had lost their luster. His hair was unrecognizable. Twenty-five years had taken their toll.
"Nete, are you here? You're the last person I would have expected to see in such company," he said bluntly.
She stepped to one side and drew her husband past, but her stalker was undeterred. "Don't you remember me, Nete?" came his voice from behind. "Of course you do. Curt Wad. How could you ever forget me?"
Halfway down the stairs he caught up with them.
"So you're Rosen's tart now, is that it? Imagine you, of all people, reaching such heights."
She tugged at her husband's arm to hasten him along, but Andreas Rosen was not known for turning his back on a problem. The present situation was no exception.
"Would you be so kind as to leave my wife alone?" he asked, his words accompanied by a glare that warned of rage.
"Oh, I see." The unwelcome guest took a step backward. "So you've actually lured Andreas Rosen into your web, Nete. Well done." He flashed what others might have taken to be a wry smile, but she knew better. "That piece of information seems to have completely passed me by, I'm afraid. But then I don't usually frequent such circles. Never read the gossip magazines."
In slow motion she saw her husband shake his head in disdain. Felt the grip of his hand on hers as he drew her on. For a moment she was able to breathe again. Their footsteps clattered, asynchronous echoes, urging them away.
They reached the downstairs cloakroom before the voice behind them spoke once more.
"Mr. Rosen! Perhaps you are unaware that your wife is a whore? A simple girl from Sprogø who isn't fussy about who she opens her legs for. Her feeble mind cannot distinguish between truth and lies, and—"
She felt a wrench of her wrist as her husband spun round. Several guests were trying to subdue the man who had interrupted their festivities. A couple of younger doctors leaned menacingly toward the tall man's chest, making it clear he was not wanted there.
"Andreas, don't," she shouted as her husband stepped toward the cluster of individuals that now surrounded her tormentor, but he was oblivious. Her alpha male was marking out his territory.
"I don't know who you are," he said, "but I strongly suggest you refrain from showing yourself in public again until you've learned how to behave in decent company."
The thin figure raised his head above the men who were holding him back and everyone present focused on his moistureless lips: the ladies behind the counter who were sorting the furs from the cotton coats, guests slinking their way past, the private chauffeurs waiting in front of the swing doors.
And then came the words that should never have been uttered.
"Why don't you ask Nete where she was sterilized? Ask her how many abortions she's had. Ask her what an isolation cell feels like after five days. Ask her, and leave lecturing me on social skills to your betters, Andreas Rosen."
Curt Wad extracted himself from those restraining him and stepped aside, eyes aflame with hatred. "I'm leaving now!" he spat. "And you, Nete!" He extended a trembling finger toward her. "You can go to hell, where you belong."
The room was a buzz of voices even before the swing doors closed behind him.
"That was Curt Wad," someone whispered. "An old student friend of the prizewinner, which is about the only good thing that can be said of him."
But the trap had sprung. She had been revealed.
All eyes were upon her now. Searching for signs of her true self. Was her neckline too plunging? Were her hips too vulgar? Were her lips?
They collected their coats, and the cloakroom lady's warm breath felt almost poisonous. You're no better than me, her expression said.
It happened that quickly.
She lowered her gaze and took her husband's arm.
Her beloved husband, whose eyes she hadn't the courage to look into.
She listened to the quiet purr of the engine. They had not spoken a word to each other, staring past the swish of the windshield wipers into the autumn darkness through which they passed.
Perhaps he was waiting for her denials, but she had none to offer.
Perhaps she was expecting him to accommodate her. To help her out of her predicament. To look into her eyes and tell her it didn't matter, whatever it was, and that what counted were the eleven years they had been together.
Not the thirty-seven she had lived before that.
But he turned on the radio and filled the car with jangling remoteness, Sting accompanying them south across Sjælland, Sade and Madonna over Falster and the Guldborgsund strait to Lolland. Strange, young voices in the night. The only thing that bound them together.
Everything else was gone.
A few hundred meters before the village of Blans, still a couple of kilometers from the manor farm, he pulled in to the edge of the fields.
"Now tell me," he said, his gaze fastened to the darkness outside. His words were without warmth. He didn't even utter her name by way of comfort. All he had was Tell me!
She closed her eyes. Pleaded with him to understand there were underlying events that explained everything, and that the man who had confronted her was the very cause of her misfortune.
But apart from that, what he had said had been the truth. She admitted it, her voice a whisper.
It was true. All of it.
For an agonizing, all-consuming moment only his breathing was heard. Then he turned toward her with darkness in his eyes. "So that's why we've never been able to have children," he said.
She nodded. Pressed her lips together and told it like it was. Yes, she was guilty of lies and deceit. She came clean. As a young girl she had been committed to Sprogø, through no fault of her own. A chain of misunderstandings, abuse of power, betrayal. There was no other reason. And yes, she'd had abortions and had been sterilized, but the dreadful man they had just encountered . . .
He laid his hand on her arm, and its coldness went through her like an electric shock, prompting her to stop.
Then he put the car into gear, released the clutch, and drove slowly through the village before accelerating quickly past the meadows and the darkened view of the water.
"I'm sorry, Nete. But I can't forgive your allowing me to live all these years blindly believing we could become parents together. I simply can't. And as for the rest of what you've told me, quite frankly I'm disgusted."
He paused, and she felt an icy tingle at her temples, the muscles of her neck tensing.
He raised his head. Arrogantly, the way he did when negotiating with people he deemed unworthy of his respect. Confidently, as when ignoring poor advice.
"I shall pack some things," he said firmly. "In the meantime, you have a week to make other arrangements. Take whatever you need from Havngaard. You won't be left wanting."
She turned her face slowly away from him and stared out over the sea. Rolled the window down slightly and drew in the smell of seaweed borne by waves as black as ink, waves that might take her once and for all.
And the feeling returned to her of lonely, desperate days on Sprogø, when the same lapping sea had tried to lure her into putting an end to her miserable life.
"You won't be left wanting," he had said, as though it mattered.
He knew nothing about her.
She glanced at her watch and fixed the date in her mind, the fourteenth of November 1985, and felt her lips quiver as she turned to look at him.
His dark eyes were cavities in his face. Only the bends in the road ahead claimed his interest.
She lifted one hand slowly and grasped the steering wheel, wrenching it to the right as hard as she could just as he opened his mouth in protest.
The engine roared in vain as the road vanished beneath them, and as they hurtled through the windbreak the sound of rasping metal drowned out her husband's final protests.
When they hit the sea it, was almost like coming home.

Five thoughts, Five Quotes:
1-The student section put on a great show for Dominic Cheek. The coveted recruit from St. Anthony sat three rows behind the Rutgers bench and got the red carpet treatment from the vociferous crowd of 4,752, which unfurled a 30-foot banner that read, "Dom, there's no place like home" and broke into chants of "We want Dom" and "Stay in Jersey." My favorite: A t-shirt that read, "Cheek and Rutgers: Yes We Can." It didn't hurt that Cheek's old high school teammate, Mike Rosario, dominated the game with 27 points on 10-of-18 shooting.
2-Solid line for J.R. Inman in 21 minutes off the bench: 6 boards, 6 points on 2-for-3 shooting, 2 blocks, 2 steals.
3-Excellent transition defense by the Scarlet Knights.
4-Somebody finally turned down the heat at the RAC. The gym was considerably cooler compared to the sauna last weekend against Marist, when three Rutgers players cramped up down the stretch.
5-Notes and observations: Former governor Richard Codey was in attendance. Codey, an ardent Seton Hall booster, donned a red sweater for the night but kept an eye on the TV in the media room as the Pirates lost to Memphis 84-70 in Puerto Rico. . . former NBA star Ron Harper, who was in the area for a golf outing, took in the game . . . sophomore guard Earl Pettis had to get stitches on his chin due to a second-half collision . . . assistant coach Jim Carr was not on the bench because he was out recruiting . . . Rutgers now holds a 35-3 record all-time against Northeast Conference teams.
Hamady on the team's hustle: "I'm personally a little crazy when I get on the court. I don't care about getting banged up. I'll always give it 100 percent. Being a captain on this team helped me rub that off on every single play on this team. I feel great when everybody jumps on the floor, when everybody is hustling. Nobody cares about an elbow in the face. We're not going to say at the end of the game, maybe we should have done this or that. All I think we should say at the end of games is we did our best and that's the mentality we have with this team right now."
Hamady on Rosario: "Watching him do what he did today was really exciting. Knowing I didn't have a chance to do what I did in Delaware—they really did a great job fronting us, me and Gregory (Echenique), and not letting us get the ball— I feel glad the guards picked us up and did what they did."
Fred Hill on the fans: "The student section has been awesome, in a word. They came out against, they came out here again today. We appreciate it.
This place can be one of the most feared arenas in college basketball when we have support like that."
Hill on the defense: "Defensively as a team I thought it was our best effort of the season. What I was concerned about, we haven't been good in transition defense. I was very concerned because Robert Morris can really get out and run on you and get easy baskets. In that phase of the game we have to carry over and keep growing."
Another from Hill: "In the first half I thought we settled for some quick shots. I thought we settled down a little bit in the second half. Our guards got extremely aggressive going to the basket. That loosened up their defense a little bit and that gave Mike some great looks and he was able to knock down some shots."

Relax — After you've signed up for Search Console, you'll receive email if any unusual events occur with your website. Unusual events include indications that your website has been hacked or problems that Google had when crawling or indexing your site. We will also email you if we detect that your site violates any of Google's search quality guidelines.
Every month or so, take a look at your Search Console status; the status page is the simplest way to get a quick health check on your site:
- Make sure that you aren't experiencing an increase in errors for your site.
- Check that you don't have any unusual dips in your click counts. Note that a weekly rhythm of weekend dips, or dips or spikes over holidays, is normal.
When your content changes
Check Search Console whenever you make important site changes to monitor your site's behavior in Google Search.
Adding new content to your site:
- Test that Google can access your pages using the URL Inspection tool.
- Tell Google which pages to crawl by updating your sitemap.
- Tell Google which pages not to crawl using robots.txt or noindex tags.
- A few weeks after you post content, confirm that the number of indexed pages in your site is rising.
Adding new properties:
- We recommend using a single site that adapts to users on any device, but if you decide to have a separate site for mobile users, be sure to add it to Search Console, and add <link rel="alternate"> tags to connect it to your existing site.
- For sites targeted at a specific country or language, follow our guidelines for international or multilingual sites.
If you change your site's domain name:
- Use the change of address tool to point Google search to your new location.
Removing a page from search results:
- Use the Remove URLs tool and take other appropriate steps to block crawling and/or indexing.
More topics
Everyone asks us this question. The answer is: there is no secret, there are only good practices. Here are the best practices for improving your site's appearance in Google search results:
- Provide high quality content on your site. Google tries to find the best answer for our users' requests; if you write the best material, you're in the game. Use the Performance report to see which queries lead to your pages, and what the click-through rate is for links to your site.
- Make sure that you follow our guidelines for good sites and avoid pitfalls that could affect your search rankings.
- Make your site mobile friendly. Many users search on mobile devices; our search results favor pages that we think answer the user's request best with the best possible user experience on their platform.
- Use informative titles and snippets. Good, clear titles and accurate meta tag descriptions help us understand the purpose of a page and generate useful snippets in our search results. Learn more.
- Add search features such as stars, event information, or site search boxes, which add to the user experience, making your site more valuable to readers.
The reports in Search Console are organized according to the general outline of the Google Search pipeline: Content is first crawled (discovered), then it is indexed (parsed and analyzed for content), after which you, the website owner, analyze the search traffic to your site and also consider how search results are displayed to the user or linked to by other sites.
Google's web crawlers follow links and sitemaps to generate a list of publicly available URLs to visit and index for content. This is the first step in the process of being added to Google's search results.
- Property
A generic term for a website that you have added to your Search Console account. You can see a list of your properties on your account homepage.
- Verify
To prove that you own the website referred to in your Search Console account. A property must be verified before you can start seeing any data for it. You'll be asked to verify a site after you add it to your Search Console account.
- Googlebot
Google's web crawler. Google has a few different Googlebots that request your pages as different device types (a smartphone, a feature phone, or a desktop computer) to calculate different search results for users searching on these devices.
- Canonical
If you host the same page at different URLs, your search results can be diluted across these duplicate pages. For example, you might have the same page at http://example.com/dogs and http://www.example.com/dogs; a search might then show separate, lower ranked results for each page than if you had only a single page. In this case, you should indicate to Google that these pages are the same, and choose one to be canonical (the official page) to show in search results. Indicate canonical pages or sites using a Sitemap, HTML tags, or Search Console settings.
- robots.txt
The name of a file on your site that tells Google which pages not to index or show in search results.
- Sitemap
A list of URLs in your site that Google uses as starting locations to begin crawling a website. A sitemap is contained in one or more files stored on your website.
The process of visiting URLs and analyzing the content and meaning of each page. This helps Google determine the best search results for a user's query.
- Resource
A web page typically loads many additional resources such as CSS, JavaScripts, and images. Be sure that Googlebot isn't blocked from accessing any resources that affect the meaning of the page during the indexing process.
- Render
Google tries to display all pages that it indexes in order to view the page as a user would. Rendering is the process of displaying the page with the images and layout to help Google analyze the meaning of the page.
Search traffic
- Manual action
If your page violates one of Google's quality guidelines, such as spammy content, it can be subject to a manual action, which will demote it in Google search results.
- International targeting
Explicitly targeting your search results at users by language or country. This can be done using hreflang link tags or the country targeting setting in Search Console.
Search appearance
How your page appears in search.
- Structured data
A standards-based way of describing information about your pages, in a format that the Google crawling engine understands. For instance, you can add ratings, event information, or video information. Some types of structured data are used to create rich results.
- Snippets
The small descriptive lines of text that appear under each result in Google search results. These are generated programmatically by Google during indexing, and can have visual characteristics known as rich results.
- Rich result
A visually enhanced Google search result, such as star ratings or event times. Rich results are often generated from structured data added by the page author.
- Sitelink
If your website has a logical hierarchy or structure, Google might display a set of sub-links below the main search result. For example, for an airline site, the main result will be the airline home page, and the smaller links below would be direct links to the booking page, the flight status page, the baggage policies page, and so on. You cannot specify sitelinks for your site.

5000+-square-foot house on market for $137,900
WINNER, S.D. — The century-old house has five bedrooms, four bathrooms, more than 5,000 square feet — and a $137,900 price tag.
In an industry were location is everything, this property is here in south-central South Dakota, where the population just shy of 3.000. And its owner wants it sold fast.
"It's a really neat house. It's been around here a long time," said listing agent Rick Shippy, who owns Shippy Realty in Winner with his wife, Lin.
Shippy grew up around the two-story corner house, dubbed the Read Mansion for former owner Mabel Read.
Incredible Jersey Shore kitchens you'll want
"It's a big, big, house," Shippy said. "Pretty rare."
Residential real estate priced at more than $100,000 is rare enough in Winner. Shippy estimates that five homes list for that much each year, "but nothing with this kind of square footage."
It's not just the 5,575 square feet at a price of less than $25 per square foot but the unique look of the property that is capturing attention.
The Read Mansion was built in 1914, and no one really knows the story of how or why it was built here, Shippy said. But local legend includes an account of multiple houses being moved to the area and joined together.
It has newer-than-100-year-old stucco exterior, a 690-square-foot basement — larger than many Manhattan studio apartments — an addition built in 2002, and central heat and air conditioning.
For much of the 20th century, the Read family owned it then sold it to a local business owner who made some updates and upgrades to the utilities. He moved and sold it to a surgeon who turned it into a hunting lodge.
After the surgeon passed away, the estate rented the home to another doctor in the area.
But it's now time to sell, Shippy said. And he has no shortage of inquiries even in the middle of winter when the temperature has stayed below freezing all day.
Since going on the market Jan. 3, Shippy Realty has taken dozens of calls and watched the listing spread almost virally online, sending 22,000 hits to the company's website the first day it was up.
"We're getting comments from California, Florida, all over the country," Shippy said. "I think there were hunters that had stayed in it hunting from different states. People are sharing it all over the country."
The home still could function as a hunting lodge, but it also is set up as a single family house, albeit a uniquely designed one.
Judge: S.D. 'Monster house' must be rebuilt or moved
Former owner Read was "an extremely eccentric lady" who likely appreciated the home's multiple parlors, winding floor plan and Italian chandeliers, Shippy said.
The other day, 14 people were inside looking it over, Shippy said he told his wife to make sure all of their cars were gone later.
"I'm not sure we'd hear if anyone was in the house," he said. "You can get lost in there."
The house appraised at $235,000 a few years ago, Shippy said. A new owner likely will want to make improvements, but it's not in bad shape.
"It needs some work. It needs maybe some new windows. There are some little things, but the house is move-in ready," he said.
And while it's more than priced to sell, Shippy reminds interested parties of two things:
1. Someone has to be able to afford to operate it.
2. It's in a small town in south central South Dakota.
"Everyone's like, 'Why's it so cheap?' Well, it's Winner, S.D. It's what we call supply and demand," he said. "It's extremely hard to find anybody that wants a 5,600-square-foot home. It's double the size of most big homes in town."
Even so, "I'll be shocked if we don't have an offer by 5 p.m. Friday," he said. "I think it will be sold by next Friday at that price."

Universal Pulse
311 Records/ATO Records
Universal Pulse—311's tenth studio
release—is rife
with their signature
tasty-waves-and-a-cool-buzz vibe. The
Omaha, Nebraska,
bunch acknowledges that much of their success
and fan base has been built off years of relentless
touring, so word is they took to their Hive
Studio looking to create stage-ready songs.
With producer Bob Rock onboard
again—he also worked on '09's
Uplifter—Universal Pulse's guitar parts are larger and
thicker than life, with articulate crunch, and
they even tastefully dip into arena-rock mode
during guitarist Tim Mahoney's harmonized
solos in "Rock On." Mahoney's gritty, ska-rock
riffing on "Time Bomb" and "Wild
Nights" creates the familiar head-bobbin'-
and-hypnotic vibes that go so well with the
good-time rhymes of Nick Hexum and S.A.
Martinez. The album's first single, "Sunset
in July," has Mahoney going back to his bag
of riff tricks and conjuring a snake-charmer-style
intro that hearkens toTransistor's
"Beautiful Disaster." Its super-simple, groovin'
rhythm and sing-along chorus are
classic 311. While the album doesn't boast
any true ballads—something they've excelled
at on previous recordings—"Trouble" starts
with P-Nut laying down a creeping bass
line that's countered by an intoxicatingly
barebones distorted guitar riff that carries the
song toward upstroke-driven euphoria. And
"Count Me In" is a fun-loving jam that has
Mahoney using his trusted Mu-Tron III for
bubbly tones à laFrom Chaos's "Amber." And
the funky arcade-game-like "And a Ways to
Go" is driven by a galloping, envelope-filter-treated
bass line.
WhileUniversal Pulsehas only eight songs,
it's more of the same tasty 311 cocktail—a
shot of reggae, a shot of rock, and a garnish
of funk—that's perfect for summertime
chillin', coastline cruisin', or afternoon grillin'.

The Nikon 1 S1 sports a 10.1-megapixel CX-format CMOS sensor. Paired together with Nikon's powerful EXPEED 3A image processing engine, these CMOS sensors deliver stunning high-quality images and HD video even in challenging lighting situations with rich detail. For complete shooting versatility, both cameras feature a wide ISO range, from 100 to 6400 in the S1, allowing users even more freedom and capabilities when capturing content in low-light situations. The S1 offers a wide and bright 3-inch LCD screens as well as a new integrated flash that can be setup to go off automatically or can be manually popped up based on a shooter's desired results.
Additionally, the Nikon 1 S1 offers Nikon's Advanced Hybrid Autofocus (AF) system, which is lightning fast and highly responsive, ideal for capturing life's split second moments. With this rapid AF system, users can take advantage of incredibly fast shooting speeds, allowing them to capture fast action that is sharp and in clear focus. The camera also features a 73-point AF array that helps ensure accuracy and super precise focus even when capturing fast moving subjects throughout the frame. Further, the Nikon 1 S1 includes the world's shortest release time at approximately 80 milliseconds*, and the world's fastest high-speed continuous shooting** at 15 frames-per-second with continuous AF .
Creativity Unleashed: User-Friendly Shooting Modes and Controls
Designed to take creative freedom to new heights, the Nikon 1 S1 offers user-friendly shooting modes and controls that photographers can take advantage of whether capturing a family portrait or recording a video of the big hit at a ballgame. For easier control and quick access to camera features, the S1 features a graphic user interface (GUI) based mode selection designed to be easy-to-use and make menu navigation effortless and direct.
The new Nikon 1 System cameras feature unique shooting modes like Auto Mode, Creative Mode, Advanced Movie, Motion Snapshot and Best Moment Capture, all of which are easily accessible and applied. When in Auto Mode, the S1 will automatically select the optimal settings for the scene, so that the shooter can concentrate on framing the photo. When in Creative Mode, shooters can utilize full manual exposure controls (P,S,A,M) as well as Selective Color, Miniature, Soft, Night Landscape, Backlighting and Night Portrait modes to help achieve the desired results that they seek.
The Advanced Movie Mode is integrated into the new camera to bolster video capabilities. When in Advanced Movie Mode, the simultaneous shooting of Full HD video and high-resolution stills of a subject or scene is achievable. Furthermore, full manual exposure controls (P,S,A,M) can be used and slow motion movies at both 400 fps and 1200 fps can also be captured when in this mode. The S1 has the Enhanced Motion Snapshot Mode to provide users with the option of capturing a quick passing moment with a short, slow-motion movie sequence in addition to a single defining still image. When using Motion Snapshot, in-camera electronic Vibration Reduction (eVR) can be applied to assist in removing blur from images.
With Best Moment Capture Mode, the Nikon 1 S1 camera can explore the benefits of two dynamic features, Slow View and Smart Photo Selector. In Slow View, the pressing of the shutter button halfway down once focus is achieved will allow users to capture live action (approx. 1.33 seconds), while the view of the subject is displayed at five times slower than normal speed (approx. 6.66 seconds) on the camera's LCD screen. Furthermore, the slowed-down view is looped over and over until a full-press of the shutter is made. By viewing action slowed down, users have more opportunities to capture the perfect moment. When Smart Photo Selector is used, shooters can capture up to 15 shots with the S1 with one press of the shutter button. The cameras will then automatically identify the five best images to keep based on exposure, focus and facial recognition factors.

On Sunday, the iceman goeth. Unless you happen to be Nathan Lane's long-lost great-uncle from Tipperary, or come with your own pot of gold, good luck getting a ticket.
At press time, it was not yet clear whether Robert Falls' Goodman Theatre production goeth for good after this weekend or whether it cometh to Broadway. Broadway mogul Scott Rudin — who could be seen collecting a Tony Award for his revival of "Death of a Salesman" last weekend — has passed on his option to produce the show in New York. Rudin, who did not see the production in Chicago, doubtless figured out that "Iceman" is a tricky commercial prospect: a big cast, Chicago actors who would need housing, a likely limit of six shows a week and the kind of daunting running time that could end up costing so much overtime that the members of Local 1 could afford to buy Harry Hope's bar out from under the poor sap. In some ways, the most logical destination for this production would be London's National Theatre, which imported the Steppenwolf Theatre's similarly seminal production of "August: Osage County," and that is one of the very few noncommercial theaters in the world with the resources to restage this production.
Then again, this is the very rare Chicago show that showcases the city's famously intense actors and yet also comes with not one but two bona fide stars of the North American theater, Lane and Brian Dennehy. With its New York reviews already in the bag (mostly), "Iceman" is a prestige-producing play, and Broadway producers love making prestige plays. And for all the public talk of we-just-did-it-for-Chicago, there are some very ambitious and persuasive men, not the least being Dennehy, involved in this enterprise. Lane said in a recent public appearance that this was the work he was most proud of in his entire career — and that's a formidable career. So it's reasonable to assume that Lane would not be expecting the same level of financial consideration he enjoyed for "The Addams Family." I bet he'd work for scale, if the whole cast went. So some producer will surely figure out that this is all doable in a limited-run situation with modest salaries in a reasonably big house and if tickets are more like, say, $199 or $299 a pop. Given that many "Iceman" tickets commanded three figures and that people pay up to $300 for"Rock of Ages" on Broadway, that's not as outrageous as it sounds.
Assuming this comes together, it will once again be a big Chicago fall on Broadway, with the top-drawer Steppenwolf Theatre production of "Who's Afraid of Virginia Woolf?"landing at the Booth Theatre in October and Debbie Bisno's new production of Craig Wright's heavily revised drama "Grace" also on tap at a theater yet to be announced, replete with Chicago director Dexter Bullard and longtime Chicago actor Michael Shannon in a lead role. One could easily imagine Shannon, Tracy Letts (in "Virginia Woolf"), Dennehy and Lane all vying for the best-actor Tony at next season's awards, with Carrie Coon (also in "Virginia Woolf") having a chance for best supporting actress. I'm making my reservations to see that come down.
But in the meantime, it's worth pausing to note that "The Iceman Cometh" at the Goodman Theatre will, whatever does or does not happen in the future, stand tall as one of the most significant productions in Chicago theater history. The ensemble acting in this production was utterly formidable in its human veracity and theatrical intensity — hauntingly so, in fact. I'm surely not alone in the way these performances have stayed with me these last few weeks. Frankly, I don't want to single out anyone, because the achievement was fundamentally collective. It was impossible to sit in a seat without knowing that you were watching a group of men and women doing the best work of their careers.
"Iceman" was also a further reminder of the dedicated audience for serious theater in this town. Tickets flew out the door, and very few seats emptied before the final curtain, even though it was close to midnight by then. Readers who've written to me have expressed their pride in the work. In the promotional run-up to the Olympics, I've been struck by how shrewdly Britain is emphasizing its role as an exporter of culture. Even if the importers end up being just those who went to the Goodman, "Iceman" was still a Chicago export easily on a par with deep-dish pizza.

Bell-diagonal states are 2-qubit states that are diagonal in the Bell basis. Since those states lie in $\mathbb{C}^{2} \otimes \mathbb{C}^{2}$, the Peres-Horodecki criterion is a sufficient condition to show separability and it's also pretty easy to check: $\rho = \sum_{i \in [0,3]}\lambda_i|\psi_{i}\rangle\langle\psi_{i}| $ is PPT (or separable) if and only if $Tr(\rho) \geq 2\lambda_i \geq 0$ for every $i$. (Here {$|\psi_{i}\rangle$} are the Bell states)
In my research I am dealing with a generalization of those states. In particular, my question is about states in $\mathbb{C}^{2^d} \otimes \mathbb{C}^{2^d}$ that are diagonal in the basis given by the $d$-fold tensor product of Bell states.
For example, for $d=2$, the states I am considering are diagonal in the basis: $$ |\psi_{0}\rangle\otimes|\psi_{0}\rangle,|\psi_{0}\rangle\otimes|\psi_{1}\rangle, \ldots,|\psi_{3}\rangle\otimes|\psi_{3}\rangle. $$
I am wondering the following:
are there some nice criteria already known to check when these states are PPT or separable?
Notice that those states are in general different from the states diagonal in what is called the generalized Bell basis in literature.
