Closterium
Closterium is a genus of desmid, a group of charophyte green algae. It is placed in the family Closteriaceae. Species of Closterium are a common component of freshwater microalgae flora worldwide.
20231101.en_13202411_1
https://en.wikipedia.org/wiki/Closterium
Closterium
Closterium is a diverse genus consisting of solitary cells, each made of two identical halves called semicells. Usually they are microscopic, but the largest can become easily visible to the naked eye. Cells are many times longer than broad, and are variously elongate to lunate (crescent-shaped). The poles are rounded, truncated, or pointed. The surface of the cell may be smooth or decorated with various features, such as striations or punctae. The cell wall is transparent, but with age it may become dark brown due to accumulated iron and manganese compounds. The cell nucleus is located in the middle of the cell. Each semicell contains a single axial chloroplast dotted with several pyrenoids.

https://en.wikipedia.org/wiki/Closterium
Closterium
At either end of the cell, there is a generally a polar vacuole. The vacuoles often contain conspicuous barium sulfate crystals.

Closterium
The Closterium peracerosum-strigosum-littorale (C. psl) complex is a unicellular, isogamous charophycean alga cells that is the closest unicellular relative to land plants. These algae are capable of forming two types of dormant diploid zygospores. Some populations form zygospores within single clones of cells (homothallic), whereas others form zygospores between different clones of cells (heterothallic). The heterothallic strains have two mating types, mt(-) and mt(+). When cells of opposite mating types are mixed in a nitrogen-deficient mating medium, mt(-) and mt(+) cells pair with each other and release protoplasts. This release is then followed by protoplast fusion (conjugation) leading to formation of a diploid zygospore. Sex pheromones termed protoplast-release inducing proteins produced by mt(-) and mt(+) cells facilitate this process.
20231101.en_13202411_4
https://en.wikipedia.org/wiki/Closterium
Closterium
A homothallic strain of Closterium forms selfing zygospores via the conjugation of two sister gametangial cells derived from one vegetative cell. Conjugation in the homothallic strain occurs mainly at low cell density and is regulated by an ortholog of a heterothallic sex-specific pheromone.
20231101.en_13202411_5
https://en.wikipedia.org/wiki/Closterium
Closterium
Although self-fertilization employs meiosis, it produces minimal genetic variability. Homothallism is thus a form of sex that is unlikely to be adaptively maintained by a benefit related to producing variability. However, homothallic meiosis may be maintained in Closterium peracerosum as an adaptation for surviving under stressful conditions such as growth in nitrogen depleted media at low cell density. A proposed adaptive benefit of meiosis is the promotion of homologous recombinational repair of DNA damages that can be caused by a stressful environment

Closterium
Like other desmids, Closterium is found in freshwater habitats. Closterium is usually attached to sediments or aquatic plants, but may sometimes be planktonic, i.e. free-floating in the water column, or found in wet soils. Most species prefer oligotrophic and slightly acidic waters, but a few species (for example Closterium aciculare) prefer eutrophic, slightly alkaline lakes.

Cosmarium
Cosmarium is a genus of freshwater organisms belonging to the Charophyta, a division of green algae from which the land plants (Embryophyta) emerged.
20231101.en_13202425_1
https://en.wikipedia.org/wiki/Cosmarium
Cosmarium
In this large genus the cells are very variable. All are constricted in the middle leading to its bi-lobed appearance; the two halves are called semicells. Cells come in a variety of different shapes. The cell wall may be smooth or ornamented with spines, granules, scrobiculations (pits), or pores. Cells are generally flattened. Cells usually have one or two chloroplasts filling the cell; each chloroplast contains pyrenoids, typically one or two.
20231101.en_13202425_2
https://en.wikipedia.org/wiki/Cosmarium
Cosmarium
Species identification of Cosmarium depends on the shape of the cells and their ornamentation, and can be difficult. In addition, the genera Actinotaenium and Euastrum can be similar to various species of Cosmarium. Actinotaenium is generally circular in cross section, and Euastrum usually (but not always) has a notch at the tip of each semicell.

Cosmarium
Cosmarium is the largest genus of desmids, with over 1,000 species. It is an artificial genus: the defining characteristics of the genus are vague and arbitrary, and there are some species that are intermediate between several different genera. It is also not monophyletic, as molecular phylogenetic studies have shown that the form of Cosmarium evolved independently many times over. Despite this, the genus is still in use, because there is no known way of classifying desmids in line with their evolutionary history.
20231101.en_13202425_4
https://en.wikipedia.org/wiki/Cosmarium
Cosmarium
Cosmarium and other desmid genera tend to prefer oligotrophic, somewhat acidic water habitats, but some species exist in more eutrophic and/or basic habitats. Some species, which are small and mostly plain, form a community known as a "Cosmarietum"; these may be further associated with a community of Closterium species forming a Cosmarietum-Closterietum association.

https://en.wikipedia.org/wiki/Desmidium
Desmidium
Desmidium is one of the filamentous desmid genera characterized by rather firm intercellular connections. Cells connect to adjoining cells at the flat, apical face of the cells. The cells can be longer or shorter than wide. A median constriction of the cells may appear either as distinct or faint. Desmidium cell walls are smooth with multiple side-by-side or scattered pores. Every semicell contains one stellate chloroplast. Typically cells are oval in shape or have a three to five angle. Angles of the cell are often off-balance on each semicell. This creates a helical shape of angles throughout the filament. Cells may have either a pyrenoid (transparent structure) in each of its lobes or a single pyrenoid in the middle of the cell. The nucleus is found in the conjoined area of semicells (isthmus). After cell division daughter cells stick together so that the filament in question increases in length. Moreover, cell filaments are markedly twisted, to be seen from a gradual shift in position of the cellular lobe facing the observer. In case of conjugation (almost) all cells in the paired filaments are sexually activated, resulting in a series of zygospores coupling the empty cell filaments

In May 1938 the dockworkers of the United Fruit Company were on strike. Bustamante and Grant were known as orators promoting and directing the strike. Both were arrested on 24 May, and remanded in custody by a police inspector. While Bustamante submitted to arrest, St. William Grant protested and was badly beaten. Both were charged with inciting unlawful assembly and obstructing the police, were refused bail and as a form of humiliation were stripped down to their underwear. The events led to further strikes and riots, until Bustamante and Grant were freed by a court on 28 May.

Grant had a falling out with Bustamante and never became part of the Jamaica Labour Party. In 1947 he contested the West Kingston division for the People's National Party in the first Municipal (KSAC) elections after adult suffrage and was beaten by more than 2 to 1. He never resurfaced in any other political contest. However, in 1950 Bustamante recommended that Grant be appointed watchman at the central Housing Authority (later the Ministry of Housing) in which post he remained until his death.

Ebb and flow hydroponics
Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition to the plants but which anchors the roots and functions as a temporary reserve of water and solvent mineral nutrients. The hydroponic solution alternately floods the system and is allowed to ebb away.

Under this system, water-tight growing containers are filled with a inert growing medium. A medium can consist of Expanded clay aggregate, rockwool cubes, or other inert materials. This is periodically flooded for a short period with a nutrient solution pumped from a supply tank. The solution then is either pumped or flows by gravity back to the supply tank. This hydroponic growing system can be very effective for any size plants depending on space. The method is inefficient in its use of water and plant nutrient reagents. Root disease occurrence and nutrient element insufficiency can occur without repeated use of the solution without proper oxygenation of the containers that are flooded. Because it is a "closed" system, the re-circulated nutrient solution requires monitoring every time the system flows back the reservoir for pH and PPM. Within the growing period, the nutrient solution may require replacement. The rooting medium may require washing to remove root debris and accumulated precipitates as well as sterilization if it is being reused.

root zone. It often involves relatively sophisticated mechanization processes which can be daunting to casual hobbyists. Nutrient solutions must usually be below the temperature at which pathogen growth can begin, yet not so cool that root activity is suppressed. Active aeration of the fertilizer solution is common, since root systems themselves remove oxygen, creating conditions which also can promote pathogenic bacteria and water-borne molds.

E&F utilizes the fact that the solution is not left in constant contact with the roots of plants, to avoid the need for oxygenating or chilling of the solution. Instead it relies on characteristics of root function to provide passive oxygenation at a high level which tends to suppress pathogen growth.

Simplicity is maintained through usage of a single, two-directional path for the solution. Water flows in and out using the same tube. When the pump has raised water into the tray, briefly submerging the roots, the pump is rendered inactive using a switch, typically a timer, and the water flows or is pumped back down the same tube.

Ebb and flow systems come on according to the water-holding capacity of the medium in which the roots sit. Highly water-retentive media can require watering only once a day, while others require two to as many as six floodings. The time it takes to flood the roots is not a critical parameter, which means that pumps are often moderate in capacity and can be small for systems sustaining indoor plants. This makes the method popular with amateur and urban gardeners. Gravity acts as drain pump in some systems, and aeration is accomplished through thin-filming and positive displacement of air as it is forced out of the root zone by water.

Aeration of an ebb and flow system is an important aspect of its operation. Automatic displacement eliminates air which has been de-oxygenated by the roots as the water rises to its highest flood stage. When the system flows back into the reservoir, it re-exposes the space around the roots to the air.

The film of water left around the roots during ebb has a high surface-to-mass ratio, which means that even as the roots absorb oxygen, its high surface area facilitates re-oxygenation, which can sustain the roots as long as their surfaces remain damp. The high oxygen content of water filmed in this way suppresses most harmful lifeforms, keeping the root zones disease free. In other types of hydroponics this function must be performed by cooling the solution to protect it from pythium, a form of water mold responsible for a condition called "root rot", in which the outer cells of the roots die, turn brown and slough off when handled. Need for supplementary oxygenation using air pumps is also eliminated, which increases reliability and reduces complexity.

Ebb and flow hydroponic systems are also quiet, while using less power than other hydroponic systems, which means that they can be used in environments where acoustic signature and excessive plumbing is objectionable, such as residential or classroom applications where space is at a premium.

Ebb and flow systems are flexible, with few practical drawbacks. Though typically known for compact cultivation of plants having smaller stature, it has been used for growing large plants, using buckets ranging in size from 1 gallon to 5 gallons, making use of high-volume pumps such as those in large aquariums, decorative fountains and koi ponds.

There are facets to these systems that present some labor investment in large-scale applications. These are primarily management of media between uses, such as washing and sterilization. This can be done by dumping into the tray and filling with a sterilizing solution such as hydrogen peroxide or chlorine solution, temporarily plugging the drain, with hand removal of root fragments. Larger containers require transferring the media to a suitable surface after sterilization to permit removal of leftover plant material.

A second drawback in designs where multiple plants are grown in the same container is that the roots tend to grow together, meaning removal of harvested or damaged plants can be somewhat problematic in plants having well-developed root systems. Commercial crops harvested at one time are somewhat immune to concerns related to that aspect of the system, but in the event of pathogenic invasion the problem can quickly spread, as all the roots share the same flood source.

Also, most ebb and flow systems use a recycling reservoir to flood the growing containers. Over a period of time the pH of the nutrient solution may fluctuate to a range which is unhealthy for the plant. If the pH is not corrected, various problems may occur, including but not limited to poor nutrient absorption and leaf cannibalization. As the name implies, leaf cannibalization occurs as the plant takes nutrients from one part of the plant and uses those nutrients in a different part of the plant. Leaf cannibalization appears as yellow or brown spots on leaves.

Poor drainage, or incomplete drainage, may cause a condition wherein dense roots are exposed to stagnant water which is trapped by the root mass. Root rot and fungal growth are the most common result of stagnant water. Some E&F systems are not as immune to root rot as a well-designed system would be. In tables where plants are larger than optimal for the system, this can create the need for modifications such as screens or beds of medium-sized gravel to prevent standing water. Tilting the tray is one way to achieve better drain characteristics. In bucket E&F this problem can be dealt with in a similar manner, ensuring good drainage through using medium of adequate size and ensuring that drainage of the container between flood cycles is complete.

Hydrogen peroxide is also added to nutrient solutions when there is suspicion that the anaerobic pythium root rot mold has begun to proliferate on the roots' surfaces. The oxygen liberated from the hydrogen peroxide is destructive to single-celled organisms and is administered in dosages which vary with the concentration of the peroxide. Typically several tablespoons or more of 3.5% peroxide solution per gallon of water are used. The temporary rise in the oxygen level is only minimally damaging to roots, while eradicating the water-borne mold can significantly increase yield or even save a crop's viability.

The Ki-4 was initially produced by Nakajima in response to a 1931 specification for a high-performance reconnaissance aircraft that could also be used in the light ground support role. After evaluating aircraft from Europe and the United States, the Imperial Japanese Army Air Force selected a new design by the domestic Nakajima Aircraft Company. The prototype was test flown in May 1934.

The first Ki-4s began equipping Imperial Japanese Army Air Force units in 1935 and were an active part of Japanese fighter squadrons for a number of years thereafter. The Ki-4s saw substantial service in the early stages of the Second Sino-Japanese War from 1938. They also functioned as light ground-attack aircraft in the support of advancing Japanese ground troops. However, these biplanes were vulnerable to even the oldest and slowest moving enemy fighters. By the time of the entry of Japan into World War II, the Ki-4s were regarded as obsolete. A number were still retained for use in the supply and liaison role from 1941, and others were transferred to the Manchukuo Air Force, but those that had not been lost in service served briefly as elementary trainers or target tugs before being scrapped. All of the Ki-4s were removed from active service by 1943.

The 2nd New York Volunteer Infantry Regiment was recruited and organized in Troy, New York to serve two years beginning on April 15, 1861. The regiment was originally raised to be commanded by New York native, George L. Willard serving in the 9th U.S. Infantry who was offered the regiment on April 24. Willard did not want to give up his regular commission for the command, so on May 10, the state turned the regiment over to Joseph B Carr, an Albany native who had risen in the New York militia to the renk of Colonel. The 2nd was accepted by the state April 24, 1861, and mustered in the service of the United States at Troy for two years on May 14, 1861.The companies were recruited primarily:
