Cultivation of Agaricus bisporus on some compost formulas and locally available casing materials. Part II: Waste tea leaves based compost formulas and locally available casing materials

Three compost formulas (formula I, formula II, and formula III) based waste tea leaves and using some activator materials such as wheat bran, chicken manure and pigeon manure were studied for Agaricusbisporus cultivation. Some locally available peats such as peat of Bolu, peat of Agacbasi, peat of Caykara and theirs mixture (80:20; volume : volume) with perlite were used. Temperature values of allcompost formulas during composting process were measured to determine the compostability level. According to results, compost temparature steadily increased until the 8th, 9th, and 9th day ofcomposting for formula I, formula II, and formula III, respectively. The maximum compost temperature values were measured for all compost formulas at the second turning stage of composting process.The highest compost temperature values were measured prepared from a mixture of waste tea leaves and wheat bran (formula I). The best mushroom yield was obtained by a mixture of waste tea leaves andpigeon manure with the peat of Caykara and perlite mixture as casing material. Peat of Caykara gave higher mushroom yield than those of other peats

Cultivation of Agaricus bisporus on wheat straw and waste tea leaves based compost formulas using wheat chaff as activator material

This study was designed to determine the pin head formation time and yield values of Agaricus bisporus on some casing materials. Composts were prepared basically from wheat straw and waste tea leaves by using wheat chaff as activator substance. Temperatures of the compost formulas were measured during composting at various depths in order to determine the compostability level. Results showed that in both compost types, maximum temperature values were recorded in the second turning stage. Composting was completed in 21 days for both composts. While the fastest pin head formation (12.50 days) was obtained on wheat straw based compost using peat of Bolu (PB) and peat of Agacbasi (PA) (50+50; in volume); waste tea leaves based compost using peat of Caykara (PC) and forest soil (FS) mixture (50+50; in volume) as casing material gave the fastest pin head formation (13.25 days). In terms of yield, a mixture of peat of Bolu and peat of Agacbasi (PA) (50+50; in volume) gave the highest yieldfor wheat straw based compost, a mixture of peat of Agacbasi and perlite (P) (80+20; involume) had the highest yield for waste tea leaves based compost

An investigation on pin head formation time of Agaricus bisporus on wheat straw and waste tea leaves based composts using some locally available peat materials and secondary casing materials

This study was designed to determine pin head formation time of Agaricus bisporus on wheat straw and waste tea leaves based composts. Locally available peat materials such as peat of Bolu (PB), peat of Agacbasi (PA), peat of Caykara (PC), and their mixture (80:20; v:v) with piece of mosaic (PM), perlite (P), and sand (S) were used as secondary casing materials. Also, some activator materials such aswheat bran, chicken manure, and pigeon manure were used for A. bisporus cultivation. For wheat straw based composts, the fastest pin head formation times were observed with a mixture of PA with PMcasing material on wheat straw and chicken manure based compost and with PA casing material on wheat straw and pigeon manure based compost. For waste tea leaves based composts, the fastest pinhead formation times were obtained with a mixture of PA with PM and PC with PM on waste tea leaves and chicken manure based compost. Generally, when peat materials were used in combination witheach other, the period of pin head formation times shortened compared to their individual use. A mixture of forest soil with sand (80 + 20; in volume) gave the worst results in terms of pin head formation times for both composts. In secondary casing materials, PM gave the best results in terms of pin head formation time for both composts

Cultivation of Agaricus bisporus on some compost formulas and locally available casing materials. Part I: Wheat straw based compost formulas and locally available casing materials

Three compost formulas; wheat straw based and using different activator materials such as wheat brain, chicken manure, and pigeon manure were used for Agaricus bisporus cultivation. Locallyavailable casing materials such as peat of Bolu, peat of Agacbasi, peat of Caykara, and their mixture (80:20; v:v) with perlite were used. Temperature degrees of all of compost formulas were measuredduring composting at various depth in order to determine the compostability level. Results showed that inner compost temparature increased until the 8th and 9th day of composting for formula I, formula II, and formula III composts, respectively. The maximum inner compost temperature degrees were measured for all compost formulas at the second turning stage of composting. The highest mushroom yield (1707.2 g) was recorded by wheat straw mixed with pigeon manure with the peat of Caykara and perlite mixture as casing material

Cultivation of Agaricus bisporus on wheat straw and waste tea leaves based composts using poplar leaves as activator material

This study was carried out to determine pin head formation time and mushroom yield of Agaricus bisporus on some casing materials. Composts were prepared basically from wheat straw and waste tealeaves using poplar leaves as activator material. In this study, moreover, in order to follow the evolution of the composting process, daily temperature measurements were taken. According to the results of the study, in both compost types, maximum temperature values were observed in the second turning stage. While in the first and second turning stages, inner-pile temperature of the compost was in atendency of exhibiting steady increase, they are prone to decrease in the following turning stages. In both composts, the period of composting has finished in 19 days. While the fastest pin head formation(13 days) was obtained on wheat straw based compost using peat of Caykara (PC) and forest soil (FS) (50+50; in volume); waste tea leaves based compost using peat of Bolu (PB) and peat of Caykara (PC)mixture (50+50; in volume) as casing material gave the fastest pin head formation (13.30 days). While, a mixture of peat of Agacbasi (PA) and perlite (P) gave the highest yield for wheat straw based compost,peat of Bolu shows the highest yield for waste tea leaves based compost

Sister chromatid exchanges in lymphocytes of nuclear medicine physicians

Objective: The aim of this study was to assess whether occupational exposure to chronic, low doses of Iodine 131 (I-131) and Technetium 99m (Tc-99m) may lead to genotoxicity. Medical personnel occupied in nuclear medicine departments are occupationally exposed to low doses of I-131 and Tc-99m. The determination of the frequency of sister chromatid exchanges (SCEs) and of cells with a high frequency of SCEs (HFC) is considered to be a sensitive indicator for detecting genotoxic potential of mutagenic and carcinogenic agents. Therefore, we examined peripheral lymphocytes from nuclear medicine physicians for the presence of both SCE and HFC

Observation of photon-induced W+W??? production in pp collisions at TeV using the ATLAS detector

This letter reports the observation of photon-induced production of W -boson pairs, γγ→WW . The analysis uses 139 fb −1 of LHC proton–proton collision data taken at s=13 TeV recorded by the ATLAS experiment during the years 2015–2018. The measurement is performed selecting one electron and one muon, corresponding to the decay of the diboson system as WW→e±νμ∓ν final state. The background-only hypothesis is rejected with a significance of well above 5 standard deviations consistent with the expectation from Monte Carlo simulation. A cross section for the γγ→WW process of 3.13±0.31(stat.)±0.28(syst.) fb is measured in a fiducial volume close to the acceptance of the detector, by requiring an electron and a muon of opposite signs with large dilepton transverse momentum and exactly zero additional charged particles. This is found to be in agreement with the Standard Model prediction

Search for Low-Mass Dijet Resonances Using Trigger-Level Jets with the ATLAS Detector in pp Collisions at root s=13 TeV

Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-jet triggers, whose data-collection rates at low transverse momentum are much lower than the rate from standard model multijet production. This Letter describes a new search for dijet resonances where this limitation is overcome by recording only the event information calculated by the jet trigger algorithms, thereby allowing much higher event rates with reduced storage needs. The search targets low-mass dijet resonances in the range 450–1800 GeV. The analyzed data set has an integrated luminosity of up to 29.3  fb−1 and was recorded at a center-of-mass energy of 13 TeV. No excesses are found; limits are set on Gaussian-shaped contributions to the dijet mass distribution from new particles and on a model of dark-matter particles with axial-vector couplings to quarks.We thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.
