Telechelic star polymers, i.e. star polymers made of a number f of di-block copolymers grafted on a central anchoring point, spontaneously and reliably self-assemble into soft patchy particles. The properties of the stars can be finely controlled by changing the physical and chemical parameters of the solution, providing a robust route for the generation of novel materials.

Haris et al, 2019. The Analysis of Water Suitability for Floating Net Sprouts in Sirah Pulau Padang, Ogan Komering Ilir District, South Sumatra Province. JLSO 8(1):20-30.The purpose of this study is to analyze the level of water suitability of the floating net sprouts in sirah pulau padang, ogan komering river, Serdang Menang Village, OKI South Sumatra Regency based on water physical and chemical parameters. This study was conducted on July - August 2018 at the Komering River, Ulak Jermun village, Terusan Menang Village, and Mangun Jaya Village, OKI District, South Sumatra. The data of sampling was divided into 3 stations, they were; station 1 was Ulak Jermun Village (3 ° 18'45.48 "LS and 104 ° 53'5.32" BT), station 2 was Terusan Menang Village (3 ° 17'14.13 "LS and 104 ° 52'46.78 "BT), and station 3 was Mangun Jaya village (3 ° 18'14.92" LS and 104 ° 52'59.48 "BT). The data of Samples were tested at the chemical laboratory in Palembang Public Water Fisheries and Extension Research Institute directly. The results of the study was for Station 1, Station 2, and Station 3 with a value was  48% with a good feasibility information. The results of measurements of water quality parameters, the pH was about 6.6 - 6.7, temperature was about from 24., 53 - 26.93oC, DO 3.93 - 4.36 mg / l, ammonia was about 0.78 - 0.16 mg / l, water brightness was about from 34.67 - 43.33 cm, CO2 4.53 - 5.03 mg / l, depth 2.36 - 2.47 m, current velocity was about 0.38 - 0.44 m / s, nitrate was about 0.37 - 0.439 mg / l, phosphate was about 0.009 - 0.225 mg / l and the bottom substrate of water was mud.

First Time

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.

The Relationship

The purpose of this study was to determine the relationship between the length and weight of Manggabai fish (Glossogobius giuris) and to know the relationship between the presence of Manggabai fish (Glossogobius giuris) and water quality in Limboto Lake. This research was conducted in February 2019, located in the waters of Lake Limboto, Gorontalo Province. The method used in determining the location of sampling is Purposive Sampling. Fish sampling is determined by considering fishing locations, litoral areas, the presence of residential areas, agricultural and plantation areas, the existence of floating net cages and in the middle of the lake. The study was conducted at 20 observation stations using fish traps in the form of bamboo and used motorcycle tires that have been modified and become traditional fishing gear. The results showed that the physical and chemical parameters in Lake Limboto and showed temperature values ​​ranged from 29.77 to 31.630C, dissolved oxygen levels ranged from 2.1 to 5.48 ppm, pH ranged from 7.09 to 8.94, TDS ranging from 0.251 to 0.369, Nitrite Levels 0.04-0.08 ppm, Nitrate Levels 1.2-4.7 ppm, BOD ranges from 2.5-57 ppm and phosphate levels 0.1-1.14 ppm. The relationship between length and body weight of fish are allometric, where W = 0.8769 L10,023 and constant b (10,023)> 3.
