Here's the How-to:
1) Prewash your fabric to remove any manufacturers' finishes that might prevent proper dye absorption. You're gonna want to iron it after for a nice smooth surface to work on.
2) Very lightly sketch out a basic composition. I used a light pencil mark that could be washed out. Vanishing fabric markers would be ideal for this purpose.
3) Fill the metal-tipped applicator bottle with Batik EZ resist and start drawing. Let dry fully. You can use a hair dryer if you're in a hurry.
4) Grab your rubber gloves and cover your work surface with plastic.
5) Place fabric on sheets of plastic wrap that has been overlapped so plastic is slightly larger than fabric.
6) Shake Rit Black liquid dye and measure out 1 Tbsp into 1 Cup of very hot 140° water and mix. Paint dye evenly across the fabric panel letting it soak well into the fabric.
Note: I was creating a grey tone with the black dye so I used a weaker dye recipe. If I was going for a pure black color, I would have doubled the amount of dye.
7) Place a layer of plastic wrap over top and seal the edges.
8) Cover bottom of microwave with paper towels. Place plastic-wrapped fabric in microwave. Set on High for 2 minutes. Wearing rubber gloves, remove from microwave. Cut open plastic wrap. Allow fabric and wrap to cool.
9) Rinse under cool running water until water runs clear. Wash in warm water with mild detergent, rinse and dry.

LEVELS OF ABSORPTION, 2004 by LAURA MAYOTTE
36”w x 20 1/2”h x 16”d
Handmade flax paper, handspun and dyed linen yarn, indigo dye.
Artist’s Statement
Levels of Absorption holds many meanings for me. Literal meanings, such as the actual absorption of the indigo dye on the pages and watermarks, and abstract meanings, such as (being a book form) how much knowledge we absorb over a lifetime, the fact that we never make use of our entire brain, that there is always room for more knowledge, learning and growth, and that also the tree-like shape adds to this idea of growth over time. All the sewing reflects the pathways of the brain and how we think; how everything is connected, how odd things can remind us of seemingly unrelated things, but they are all there and accessible. This sewing is also rather electricity-like in appearance, and metaphorically, referring to how fast our thoughts can be, our natural reflexes or responses to stimuli, and how knowledge gained over time can be instantly accessed once learned.

hortaleza, madrid
the uva (neighbourhood absorption unit) de hortaleza was built as temporary housing for displaced chabolistas (shanty town dwellers) by the government in 1963. they were provisionally planned to be used for 5 years. 45 years later just under half of them are still in existence with approxinmately 460 families still living there. they are totally deteriorated due to their cheap construction and lack of maintenance. presently the future of the uva is being decided upon in the courts.

Forests play a vital role in the functioning of the planet's natural systems. The forests regulate local and global weather through their absorption and creation of rainfall and their exchange of atmospheric gases. The Amazon alone creates 50-80 percent of its own rainfall through transpiration. Cutting the rainforests changes the reflectivity of the earth's surface, which affects global weather by altering wind and ocean current patterns, and changes rainfall distribution. If the forests continue to be destroyed, global weather patterns may become more unstable and extreme.
Lost in the Forest ~ Pablo Neruda
Lost in the forest, I broke off a dark twig
and lifted its whisper to my thirsty lips:
maybe it was the voice of the rain crying,
a cracked bell, or a torn heart.
Something from far off it seemed
deep and secret to me, hidden by the earth,
a shout muffled by huge autumns,
by the moist half-open darkness of the leaves.
Wakening from the dreaming forest there, the hazel-sprig
sang under my tongue, its drifting fragrance
climbed up through my conscious mind
as if suddenly the roots I had left behind
cried out to me, the land I had lost with my childhood---
and I stopped, wounded by the wandering scent.

Globally, forests have been cut, reducing carbon dioxide absorption and biodiversity. Land use practices have led to land degradation and desertification, as have droughts, including those linked to climate change. Women can be among the most affected, often charged with making up shortfalls in food and fuel. As stewards of the land women must have access to land, livelihoods and natural resources, and a say in how they are shared. Women, and indigenous women in particular, need to be included in decision-making on ecosystem use at all levels, as essential players in preserving our planet.

Images and spectra of a flat plate crystal of titanite (sphene) with a maximum dimension of 17mm. These are quite difficult spectra to obtain since the absorption lines seen in transmission (orange line) are very weak and the fluorescence (purple line) is very faint.
The absorption lines between 730 and 830 nm are due to neodymium (Nd^3+) while the line at 972nm is due to samarium (Sm^3+).
The strongest fluorescent emission lines are due to Sm^3+ with others possibly due to europium (Eu^3+) and chromium.(Cr^3+)
The two images at the bottom are of opposite sides of the plate crystal and taken with a linear polariser at an angle that minimises the transmission and deepens the colour.

“You have seen nothing yet”, asserts Sinead O’Brien in single Girlkind – and you are inclined to believe her. Building on her arresting releases since 2018, the multifaceted Irish poet, songwriter and performer is ascending into new territory with her debut LP, Time Bend and Break the Bower, released via Chess Club Records.
Demanding a visceral response from her audiences, O’Brien issues a challenge to those who would box her music inside a notion of tradition. Instead, the artist’s poetry – a constant, active absorption of how people speak, communicate and clash in the era we are living through – is an essential clarion call heard in the future.
Communing at the triangulation of words, music and image, O’Brien is a conjurer of powerful worlds: and none are more powerful, or as immersive, as those of Time Bend and Break the Bower. In the space that exists between her delivery – at once wry, silky, vicious, and self-assured – and the music – a dynamic, dancing call-and-response from her collaborators, guitarist Julian Hanson and drummer Oscar Robertson – lies the record’s productive tension. Using a method of creating on-instinct, in constant communication with multisensory cues, O’Brien carves out her own space as a musical oracle for an ever-shifting era. Treading her path as a poet, not a singer, is how O’Brien has forged an identity she feels is truly hers: it is, simply, how the artist has to communicate.
If O’Brien’s delivery alone issues a challenge of genre, of categorisation, what is she telling us with those words? Born in Dublin and raised in Limerick, there are no overtly explicit references to O’Brien’s home country to be found in the new record, but the atmosphere of its landscape is nonetheless found in its lyrical world..On tracks like ‘Girlkind’, and latest single ‘Holy Country’, the narrative builds from abstract memories of home, before O’Brien’s wild current drags us somewhere else entirely, issuing an urgent protest as much as an incantation. In ‘Like Culture’, she carries a poem she began writing when she was 17 – an ode to coming together with friends on dance floors – through with her into the current moment, where the healing power of movement matters now more than ever.
O’Brien wants each word to be heard – to make impact. And she is being heard. Since 2020, O’Brien’s releases – such as 2021’s ‘Kid Stuff’ single, and 2020’s ‘Drowning in Blessings’ EP – have garnered international critical acclaim, from titles like Rolling Stone, DIY, Dazed, Dork, Loud & Quiet, NME, Paste, Stereogum, The FADER, The Guardian, The Quietus, and AnOther Magazine, among others. O’Brien has also been consistently supported on national radio: she counts Jack Saunders at BBC Radio 1, and Steve Lamacq and Amy Lamé at BBC Radio 6 Music, as champions of her music, with the latter station giving two tracks a spot on their B List. And O’Brien is building on her prior US support from the likes of Seattles’ KEXP with appearances at SXSW – in virtual form in 2021, and as she brings her band to Texas itself in spring 2022.
O’Brien has also toured across the UK and Europe at a number of venues and festivals, where she has stamped her unforgettable performance style alongside her musical collaborators – an impact that has led to her being invited to tour with Belle & Sebastian later in 2022. On stage, the raven-haired artist commands attention, demonstrating a kinetic connection with Hanson and Roberston with every sentiment she voices. Live performance is a vital ingredient of O’Brien’s ongoing project – it’s here that her contemporary sonics transform into a unique on-stage vocabulary, one that both seduces and challenges.
With a background on the design teams for John Galliano and, later, Vivienne Westwood, O’Brien’s cultural touchstones also span a rich history of art, photography, film, and dance: from Helmut Newton femme fatales and Henri Cartier-Bresson’s bleak landscapes, to modern movement performance by Michael Clark and Michael Laub companies, to the writings of Virginia Woolf and Samuel Beckett. Recently tapped by Alessandro Michele’s Gucci to perform, it’s clear that O’Brien’s esoteric instincts are inspiring those in spaces beyond the music industry as well as within it.
Relentless, surreal, incendiary, O’Brien operates inside her own atmosphere even as she constantly forms her response to the contemporary world she moves through. In 2022, with the release of her debut album, festival circuit presence, and multiple tour dates, the artist is blazing a trail into the new – always questioning, and asking you to join her.
Iron Man Records will be looking after Tour Management for Sinead O'Brien on her tour dates through September and October. Come and see the band play. If you are already an Iron Man Records Patron, ask if you are after guestlist places. I might be able to find you a ticket or two.

For this gentle and relaxing photowalk in my district, Lyon, France, I brought along my French TLR SEMFLEX Standard 3.5 camera (see below for details) loaded with a never-tried yet film Svema FOTO 100 made in Ukraine. The backing paper is black with white numbering and signaling symbols are easy to read across the small red window of my SEMFLEX.
For all the frames, my SEMFLEX was equipped with the original SEMFLEX squared shade hood a SEMFLEX yellow filter x2. The film was exposed for 50 ISO to compensate the light absorption of the yellow filter. Metering was done using a Minolta Autometer III equipped with a 10° finder for selective measures privileging the shadow areas or an opale dome for incident light integration.

Parc de la Cerisaie - Villa Gillet ***, May 10, 2025
69004 Lyon
France
___________
*** ** PARC DE LA CERISAIE, WHOSE NAME COMES FROM THE PRESENCE, OLD, OF A CHERRY ORCHARD ALREADY BELONGS TO THE CITY OF LYON: SINCE 1976.
Previously owned by the Gillet family, precursors of silk dyeing at the beginning of the 20th century, the park and the Villa built in 1911 by the architect Joseph Folléa communicated at the time directly with their factory installed on the banks of the Saône. In the 60s, their vast industrial empire merged with the Rhône-Poulenc group of which Renaud Gillet was president from 1973 to 1979.
Very quickly, the City of Lyon chose to open this park to the people of Lyon and to direct its vocation towards the Arts. Thus, during the 2nd and 3rd sculpture symposiums of 1980 and 1982 the park hosted many works. Some of them are still there.
The villa, renovated in 1986, also became a place dedicated to the Arts. Initially, it was the headquarters of the Fonds Régional d'Art Contemporain (FRAC), the organization supporting creation, before it was transferred to the Institut d'Art Contemporain de Villeurbanne.
Today, the villa houses three cultural institutions: La Villa Gillet, which defines itself as a Contemporary Research Unit and is interested in all forms of culture (literature, human, political and social sciences, history, or contemporary arts), the Agence Rhône-Alpes pour le Livre et la Documentation (ARALD) whose objective is to promote the culture of writing and activities related to books, and the Groupe Musiques Vivantes de Lyon which works for the creation and diffusion of acoustic music.

After the view #12 exposed, the film was fully rolled to the taking spool and was developed in a Paterson tank with a spiral adapted to the 120-format film. 500 mL of Adox Adonal (Agfa Rodinal) developer were prepared at the dilution 1+25 and the film processed for 7 min at 20°C. The first view was shifted by about two frames leading to only 10 views on the film. This is clearly due to a quality problem. The backing paper was improperly positioned during the spooling of the film.
Digitizing of the remaining 10 frames, was made using a Sony A7 camera (ILCE-7, 24MP) held on a Minolta vertical macro stative device and adapted to a Minolta MD Macro lens 1:3.5 f=50mm. The light source was a LED panel (approx. 4x5') CineStill Cine-lite fitted with film holder "Lobster" to maintain flat the 70mm films.
The RAW files obtained were inverted within LR and edited to the final jpeg pictures without intermediate file. They are presented either as printed files with frame or the full size JPEG together with some documentary smartphone pictures..
About the camera and lenses :
My French Semflex TLR year 1959-1960 is equipped with triplet 1/3.5 f=75mm SOM Berthiot lenses as descripted bellow.
The SEM company ("Société des Etablissements Modernes de Mécanique") was founded in France by Paul Royet in 1946, in the small city of Aurec near Saint-Etienne (Loire). The SEM camera's was known essentially for the TLR Semflex that were a great commercial success in France until the 70's. The camera's are constructed around an injected aluminum alloy chassis, very resistant and rigid permitting precise optical alignments. The focusing mechanism is made of a cam system like the Rolleiflex giving an accurate and smooth focusing. SEM constructed their own shutters called Orec with 5 leaves capable of the 1/400s to 1s with B.
Semflex received in majority French optics Berthiot with 3 or 4 lenses (Tessar type). Some camera's were also mounted with Angénieux lenses.
Semflex were trusted TLR camera's used by amateurs and for professional purposes. From 1949 to 1976, 171.000 Semflex were produced in many different types and versions.
My Semflex in a middle grade version Standard 3.5 type-10 (1959-1960). It was the last version mounted with the 3-lens SOM Berthiot 1:3.5 f=75mm. I got the camera with set of accessories and several documents including the user manual of the Semflex Standard 4.5 versions. The accessories include a leather SEM ever-ready bag, a Semflex push-on shade hood, a Semflex push-on yellow filter x2 in its original box, and close-focusing lenses. The 1D one is constructed with a prism for the finder lens that compensates the parallax in the zone 1m to 0.5m.
The decorative ring around each lenses can also receive push-on accessories in 36mm diameter as the FOCA or Leitz 36mm filter series. I adapted two protective lens caps from Kodak film canister snapped covers.

Erin Beckman is a Dean’s Honored Graduate in the Departments of Mathematics and Chemistry and Biochemistry. She is graduating with honors degrees from both departments. Lindsay is being recognized for her excellent academic performance and research efforts working in collaboration with Professor John Stanton in chemistry and Lorenzo Sadun in mathematics that have culminated in an honors thesis, “Equilibrium and Non-Equilibrium Molecular Absorption: A study of the Ising model and the infinite parking limit problem.”
Erin began her research career in the FRI lab of Drs. Jones and Holliday, synthesizing polymerizable lanthanide complexes. After this, she joined Professor Stanton’s research group, studying models of chemical absorption onto surfaces. She enrolled in a Discrete Mathematics class with Professor Michael Starbird as a sophomore, and as a junior and a senior she quickly took on an additional mathematics major. It turns out that the mathematics behind chemical phenomena is surprisingly deep and requires an understanding of statistical mechanics (in her case, the Ising model of ferromagnetism), which in turn is built on the statistical study of random partitions, among other topics. As it happens, the rudiments of these ideas are presented in a Discrete Mathematics class, but the gulf is huge between that class, which she had just taken a couple of semesters earlier, and the research tools she needed for her project. Erin made remarkable progress in just a couple of semesters, and did so mostly on her own, chasing chains of references to understand the principles involved.
In addition to being a part of the Dean’s Scholars Honors Program, Erin demonstrated her excellence in many ways while at UT. She was a math and chemistry tutor at the UT Sanger Learning Center for four years. She also made the time to study abroad at Trinity College in Dublin, Ireland; in addition to exploring Ireland and Europe, she worked there in a marine biology lab and studied ancient languages like FORTRAN. She is known as an avid soccer player and took a fencing class as well. Not surprisingly, she has received a number of accolades while at UT, including being on the honor roll for three years running, winning a CNS Book Award, as well as the Dow Chemical USA Centennial Endowed Scholarship, the Chemistry and Biochemistry Authors’ Scholarship, and the American Airlines Global Leaders Travel Scholarship.
Next year, Erin plans to pursue a PhD in mathematics at Duke University, where she plans to study mathematical biology. Among the books she has chosen for her summer reading are The Power of Habit: Why We Do What We Do in Life and Business by Charles Duhigg, The Five Elements of Effective Thinking by Michael Starbird and Edward Burger, Mavericks, Miracles, and Medicine: Pioneers Who Risked Their Lives to Bring Medicine into the Modern Age by Julie M. Fenster, and Introductory Complex Analysis by Richard A. Silverman.

A Kodak Tri-X with my Zorki 1 type D (year 1955), Lyon, France, January 25 an 26, 2023. Since tenth of days, the weather was invariably very cloudy with 0-3°C (mild temperatures for a Zorki...) making the outdoor scenes very flat and colorless.
The Zorki camera was loaded with a 36-exposure Kodak Tri-X, with its leader trimmed for old Leica's. Outdoor, the Industar-22 lens was equipped with a 36mm push-on "1A" (likely the so-called "Skylight") filter and unknown brand (not FOCA) and a generic metal cylindric shade hood. Indoor, only the shade hood was used. After solving the problem of the stiff rewind mechanism, the film advance was flawless all along the 36 exposures.
Expositions were determined using a Minolta Autometer III with a 10° finder for selective measurements privileging the shadow areas. The possible slight absorption of the 1A filter was corrected by +0.5 EV.
Typically the indoor views at the Musée de la Résistance were exposed at 1/20s or 1/30s and full aperture 1:3.5 and outdoor views were at 1/60s at 1:5.6 to 1:8.
Musée de la Résistance et de la Déportation, January 25, 2023
14, avenue Berthelot
69007 Lyon
France
After exposure, the film was processed using Adox Adonal (= Agfa Rodinal) developer at dilution 1+50, 20°C for 14min.
The film was then digitalized using a Sony A7 body adapted to a Minolta Auto Bellows III and a Minolta Slide Duplicator using a lens Minolta Bellow Macro Rokkor 50mm f/3.5 at a reproduction ratio of 1:1. The reproduced RAW files obtained were processed in LR prior the the final JPEG editions.
All views of the film are presented (with resizing for overlapped ones) in the dedicated album either in the printed framed versions and unframed full-size jpeg.
About the camera and the lens:
This camera is a practically mint sample of Zorki 1 arrived to me in Lyon, France, January 10, 2023.
The camera looked exiting from the KMZ factory in USSR almost 70 years later spent in a time capsule ... with almost no traces of use. According to a custom receipt of July 28, 1955, signed in Vienna, Austria, the camera body and lens are the original matched ones. As for the original FED, FED-Zorki and Zorki's ("ФЭД", "ФЭД-Зоркий", „Зоркий“), the Zorki 1 was a straight legal copy of the Oskar Barnack Leica II after the cancelation of German camera patents following the end of WWII.
This Zorki 1 is a type D model PM1115 (year 1955 according sovietcams.com/index7584.html). Type D Zorki's were produced from 1953 to 1955 in about 250.000 units with serial numbers ranging from #470.000 to (in 1955) #55 45.000. The original lens of this Zorki units is an collapsible lens Industar-22 1:3.5 f=5cm.
In the rear pocket of the ever-ready leather bag was deposited the custom receipt and a film label of Agfa negative-color CN17 likely from the 60's.

Anhydrite is a mineral—anhydrous calcium sulfate, CaSO4. Distinctly developed crystals are somewhat rare, the mineral usually presenting the form of cleavage masses. The hardness is 3.5 and the specific gravity 2.9. The color is white, sometimes greyish, bluish, or purple. When exposed to water, anhydrite readily transforms to the more commonly occurring gypsum, (CaSO4·2H2O) by the absorption of water. This transformation is reversible, with gypsum or calcium sulfate hemihydrate forming anhydrite by heating to ~200°C under normal atmospheric conditions. Anhydrite is commonly associated with calcite and halite.
www.researchgate.net/publication/259338144_Proposal_for_A...
The anhydritic horizon is a horizon in which anhydrite has accumulated through neoformation or transformation to a significant extent. It typically occurs as a subsurface horizon. It commonly occurs in conjunction with a salic horizon.
Identification of anhydrite (75-135 cm) is important when determining soil strength. Soils high in anhydrite exhibit fluidity and lack soil strength and load bearing capacity. Moisture content strongly influences soil’s consistence and a water table is commonly within the soil profile. The manner in which specimens of soil fail under increasing force ranges widely and usually is highly dependent on water state. To test for fluidity, a handful of soil material is squeezed in the hand. For moderately fluid materials after exerting full pressure, most flows through the fingers; a small residue remains in the palm of the hand.
For example, if some of the soil flows between the fingers with difficulty, the nvalue is between 0.7 and less than 1.0 (slightly fluid manner of failure class); if the soil flows easily between the fingers, the nvalue is 1 or more (moderately fluid or very fluid manner of failure class) depending on what remains in the palm of the hand.
