Nitrat dan fosfat adalah unsur nutrien yang menjadi pembatas kelimpahan fitoplankton. Kandungan nitrat dan fosfat di perairan muara akan dipengaruhi oleh faktor biologi, fisika dan kimia perairan, yang menyebabkan timbulnya suatu persebaran. Hal tersebut menjadi permasalahan di Muara Sungai Bodri, Kendal. Tujuan dari penelitian ini adalah untuk mengkaji kandungan nitrat dan fosfat beserta pola persebarannya, serta keterkaitannya dengan struktur populasi fitoplankton sebagai bioindikator kesuburan perairan di Perairan Muara Sungai Bodri, Kabupaten Kendal. Penelitian dilaksanakan berdasarkan metoda observasi dengan pendekatan spatio-temporal. Sejumlah 9 stasiun penelitian dan 3 kali waktu sampling yaitu 30 Juni, 1 September dan 27 Oktober 2018. Kandungan nitrat dan fosfat serta kelimpahan fitoplankton ditetapkan sebagai variabel terikat. Sedangkan parameter fisika dan kimia perairan seperti suhu, salinitas, derajat keasaman (pH), oksigen terlarut, kecerahan dan arus ditetapkan sebagai variabel kontrol. Hasil penelitian menunjukan bahwa kandungan nitrat berkisar 0,49-0,9 mg/l serta kandungan fosfat berkisar 0,01-0,29 mg/l yang menunjukkan bahwa perairan Muara Sungai Bodri, Kabupaten Kendal dalam kondisi subur/eutrofik. Kelimpahan fitoplankton menunjukkan nilai kisaran diantara 2.356 sampai dengan 162.626 sel/l, yang tersusun oleh 5 kelas dan 45 jenis/species dengan pola persebaran berbentuk konvergen yang bertumpu pada stasiun 3 dan 5. Perairan Muara Sungai Bodri, Kabupaten Kendal menunjukkan tingkat kesuburan yang tinggi atau eutrofik.   Nitrate and Phosphate are the nutrient element which influence as limiting factor to the phytoplankton population. Nitrate and Phosphate in the water were influence by physical and chemical factors, and will affect to the distribution. The distribution of nitrate and phosphate will affect the distribution of phytoplankton population. The purpose of the research is to analyze the distribution of phytoplankton population due to the influence of nitrate and phosphate contents at Bodri Estuary, Kendal. The research was apllied based on the spatio-temporel approach. There are 9 stations and triple sampling of 30 June, 1st Septembre and 27 Octobre, 2018. The nitrate and phosphate contents and phytoplankton abundance was set as dependent variables. The parameters temperature, salinity, pH, Dissolved Oxygen, transparency and current were used as variable control. The research result show the nitrate content range between 0,49-0,9 mgr./l and the phosphate content range between 0,01-0,29 mgr./l, which indicate that the Bodri Estuary, Kendal is eutrophic. The distribution of nitrate and phosphate contens show a model of convergen on west area of sampling and tend to along the coastline in the east part. The phytoplankton abundance show a range of 2.356 - 162.626 cell /l, which composed of 5 Class and 45 species.

During the last decade, entomologists have made progress in understanding the environment in which certain insects live; in particular, we begin to understand the effect of certain physical and chemical factors, which make up a part of the environment. With this gain in knowledge, it is sometimes possible to forecast outbreaks of insects and of diseases conveyed by them, and one can sometimes say that a particular alteration of the environment will result in loss or gain. But so far as mosquitos are concerned, one must admit that though much work has been devoted to the analytical study of the water in which the early stages are passed, the results are disappointing. A consideration of the published work suggests several reasons for this. Investigation into the ecology of the mosquito has had a vogue, and much of it has been done by workers who were isolated and whose knowledge of chemical technique and freshwater biology was limited. Apart from that, the inherent difficulties are great, for the worker must hunt for the limiting chemical and physical factors among a host of others which are doubtless unimportant, and there are few clues to indicate which of the chemical constituents of the water affects the mosquito. The data are therefore voluminous and it is difficult to reduce them to order and present them so that they can be readily understood.

AbstractWhen compared with other menadione derivatives such as menadione sodium bisulphite (MSB), menadione nicotinamide bisulphite (MNB), an organic salt combining menadione and nicotinamide, shows better stability towards physical and chemical factors once it is added to pre-mixes or foods. The present work evaluates the bioavailability of the two vitamins present in this compound and toxicity in the pig. To assess vitamin bioavailability, pigs were given small amounts of food containing MNB or equivalent amounts of MSB and nicotinamide in the free form. Menadione and nicotinamide concentrations in blood samples drawn at set times after the diets were given did not reveal any significant differences between the two modes of administration. Haematic levels of both vitamins in animals receiving MNB, or MSB and nicotinamide, were after 2, 4, 8 and 12 h higher (P < 0·001) than those of untreated animals. The tolerance level to MNB was evaluated in pigs given diets containing graded amounts of MNB (100, 500, 2500 mg/kg) for 28 days. No significant (P > 0·05) differences were recorded in live weight, food intake and gain/food ratio in pigs given these diets when compared with those given an unsupplemented diet. Haemoglobin and bilirubin levels did not differ between animals given various amounts of MNB and control animals. Plasma aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities in pigs given 100 mg/kg of MNB did not show significant differences when compared with those observed in pigs given an unsupplemented control diet. In pigs on the diets supplemented with 500 and 2500 mg/kg of MNB there was a significant increase in the two enzymatic activities as compared with controls (P < 0·001 and P < 0·01). In the case of ALT this had disappeared by 28 weeks. MNB is a good source of vitamin K for the pig and does not appear to have any adverse effects, even when administered at levels higher than those normally used in pig food supplementation.

In order to gain some picture of the seasonal variations in the plankton communities two cruises were made in the Strait of Georgia, one in June 1955, and the other in November 1955; 165 plankton collections were taken, also surface temperatures.The correlation of these data have resulted in a number of conclusions concerning the distribution of plankton in the Strait of Georgia. The chief factor affecting the general distribution of plankton is the salinity gradient. The inflow of fresh water from the Fraser River forms zones of varying properties, and leads to the development of different plankton communities. The extent to which physical and chemical factors may determine the presence or absence of certain organisms from the zones described is discussed.

Visual Impacts

At autonomous electricity grids Renewable Energy (RE) contributes significantly to energy production. Offshore resources benefit from higher energy density, smaller visual impacts, and higher availability levels. Offshore locations at the West of Crete obtain wind availability ≈80%, combining this with the installation potential for large scale modern wind turbines (rated power) then expected annual benefits are immense. Temporal variability of production is a limiting factor for wider adaptation of large offshore farms. To this end multi-generation with wave energy can alleviate issues of non-generation for wind. Spatio-temporal correlation of wind and wave energy production exhibit that wind and wave hybrid stations can contribute significant amounts of clean energy, while at the same time reducing spatial constrains and public acceptance issues. Offshore technologies can be combined as co-located or not, altering contribution profiles of wave energy to non-operating wind turbine production. In this study a co-located option contributes up to 626 h per annum, while a non co-located solution is found to complement over 4000 h of a non-operative wind turbine. Findings indicate the opportunities associated not only in terms of capital expenditure reduction, but also in the ever important issue of renewable variability and grid stability.
