Cytogenetic studies on four species of vascular coastal and water plants from Russian Far East are presented. During the present investigation the next chromosome numbers have been revealed: Gypsophila pacifica (2 n = 34), Allium sacculiferum (2 n = 32), Mertensia maritima (2 n = 24), and Nelumbo komarovii (2 n = 16). Unusual chromosome numbers for these species have not been noted but it was the first case of karyological studies of Nelumbo komarovii from the Jewish Autonomous Region and most northern habitat. The number of nucleoli in interphase nuclei of these species was counted. Interphase nuclei of studied species contain 1–4 nucleoli except in A. sacculiferum so far which have 1–2 nucleoli per cell. Different points of view on polyploidy of studied species are discussed.
Sanskrit literature abounds in lexicons. Amarakośa is the most celebrated and authoritative ancient thesaurus of Sanskrit. There are references to various lexicons in many ancient Sanskrit texts, but none of these except for Dhanvantari’s and Amarasiṃha’s are extant. Between the two, the latter’s work Nāmaliṇgānuśāsana popularly known as Amarakośa is very familiar to every student of Sanskrit. The actual name of the book ‘Nāmaliṇgānuśāsana’ means instruction concerning nouns and gender. It is divided into three kāṇḍas (volumes). Eachkāṇḍa is divided into Vargas depending on the subject they deal with. A list of more than 220 plants is mentioned with all the synonyms in the four Vargas. The plants that are revealed in the Amarakośacan be classified into huge trees, edible fruit trees, shrubs, herbs, creepers, water plants, grasses, pulses, cereals, wild cereals and others. Plants that are generally used for incensing, perfumery and cosmetics for human consumption are mentioned in the Manuṣhya Varga. In the Vaiśyavarga crops of commercial value are included.
Every human being has a feeling of saturation in carrying out his daily activities. There are many ways you can do to get rid of boredom, one of which is by doing hobbies that we like. Currently there are many hobbies that can be done, one of which is a hobby of decorating an aquarium (Aquascape) by using stones, wood, sand and using water plants. Which is starting to be of interest to various circles of society. For Aquascape owners, sometimes their daily activities are busy. In fact, these other activities can take up to days. The solution to the problem of fan negligence when maintaining the Aquascape is to build an aquarium system that can adjust the lighting periodically as needed, stabilizing the water temperature in the aquarium
This study aims to create an Arduino-based automatic plant watering system, in which the water pump can pump water automatically based on the reading from the soil moisture sensor, which aims to make it easier for people to water plants. This research was conducted at the Palopo City Agriculture Office. The results of this study indicate that users no longer need to water plants manually. In designing an Arduino-based Automatic Plant Watering System, a microcontroller and several components are used, including: Arduino UNO, FC-28 moisture sensor, water pump, relay, 16x2 LCD and breadboard. This tool works by reading data from the soil moisture sensor, if The sensor detects dry soil levels, then the data from the sensor will be read by Arduino. The data that has been read by Arduino will be forwarded to the relay, then the relay will forward the data that will be used to turn on or turn off the water pump
Centralized softening as a solution to chloride pollution: An empirical analysis based on Minnesota cities
Chloride is a key component of salt, used in many activities such as alkali production, water treatment, and de-icing. Chloride entering surface and groundwater is a concern due to its toxicity to aquatic life and potential to degrade drinking water sources. Minnesota being a hard-water state, has a high demand for water softening. Recent research has found that home-based water softeners contribute significantly to chloride loading at municipal wastewater treatment plants (WWTPs). Because of this, many WWTPs would now require water quality based effluent limits (WQBELs) to comply with the state’s chloride water quality standards (WQS), unless they install chloride treatment technologies, which are limited and cost-prohibitive to most communities. A potential solution to this problem, is shifting from home-based water softening to a system where water is softened at drinking water plants, before reaching homes, i.e. centralized softening, analyzed in this paper based on its ability to address both chloride pollution and water softening needs, at reasonable cost. We estimate lifetime costs of three alternative solutions: centralized softening, home-based softening, and a Business as Usual (BAU) or baseline alternative, using annualized 20-year loan payments and Net Present Value (NPV), applied to 84 Minnesota cities with matching data on drinking water plants and WWTPs. We find that centralized softening using either Reverse Osmosis (RO) or lime-softening technologies is the more cost-effective solution, compared to the alternative of home-based softening with end-of-pipe chloride treatment, with a cost ratio in the range 1:3–1:4. Between the two centralized softening options, we find RO-softening to be the lower cost option, only slightly more costly (1.1 cost ratio) than the BAU option. Considering additional environmental and public health benefits, and cost savings associated with removal of home-based softeners, our results provide helpful information to multiple stakeholders interested in an effective solution to chloride pollution.
<em>Plants are living things that are important for the needs of human life. The benefits of plants for humans are as an air purifier. Water is needed for plants to grow. Besides being used in the process of photosynthesis, water is also used by plants to dissolve minerals that are absorbed by the roots from the soil as a process of developing the plants. Watering can maintain and care for plants to grow and develop. The purpose of this study is to create a tool that can water plants using Android devices by utilizing an internet connection for control and monitoring. By using smartphone android that has been installed the blynk application can communicate with Arduino using an enhancement in the form of ESP8266 so that it can be connected via a WIFI connection so that it allows the user to control and monitor the plant sprinklers, by working sending commands on and off through blynk and receiving data the temperature and humidity obtained from the DHT22 sensor. The results of this study, the watering plant can work well, can control watering manually and automatically. The tool will water the plants when the temperature is more than 31 ° C</em>

Phytoremediation of Detergent Levels in Waters Using Water Plants: Eichornia crassipes, Ipomoea aquatica, Pistia stratoites and Their Combinations
Research on phytoremidiation to reduce detergent waste in waters has been successfully carried out. The phytoremidiation process is carried out using aquatic plants: Eichornia crassipes, Ipomoea aquatica, Pistia stratoites, and their combinations. The treated water sample comes from the Ancar river Mataram, NTB. The research is experimental with a randomized block design, with the procedure: Water samples are planted with aquatic plants according to the research design which serves to absorb detergent waste. Detergent levels before and after the treatment of aquatic plants were observed using the MBAS (Methylen Blue Active Substance) method. The results showed that the three water plants used were able to reduce the concentration of detergents and improve the concentration of water quality parameters (pH, DO, BOD, and COD) and which had the best ability (73.60%) in absorbing detergents was a combination of Eichornia crassipes and Ipomoea aquatic the best accumulation time of absorption occurred in the period of 7 to 14.
