Streszczenie:

A study of three newspapers that primarily serve the New Madrid Fault area shows that the press and public officials probably share the blame for public panic surrounding the 1990 Iben Browning earthquake prediction. The press failed to report soon enough scientists’ views that refuted Browning's prediction, and some public officials used mass media to promote earthquake awareness even though the tactics fed public misperceptions about the likelihood of Browning's prediction coming to pass.

Browning biasanya terjadi karena senyawa fenolik yang muncul saat eksplan dilukai. Penelitian ini bertujuan untuk mengetahui metode yang efektif mencegah dan menurunkan intensitas browning dengan penggunaan senyawa anti-browning yaitu asam askorbat dan arang aktif yang diinkubasi pada kondisi terang dan gelap.

Abstract Browning on in vitro culture is one of the problems in somatic embryo regeneration that leads to growth inhibition and death of explants. This study aimed to prevent and control browning of oil palm somatic embryos (SE) in the Temporary Immersion System (TIS). The research was conducted in two stages; the first stage was applying an antioxidant mixture at concentrations of 20, 50, and 100 mg L-1 on the browning palm oil SE in TIS. The second stage was carried out by modification of the basal media, namely DF (control), MS, SM, and SMT. The explants used in experiment 2 were browning a

Saurauia bracteosa, also known as Pirdot, is an endemic woody plant of the Actinidiaceae family with medicinal properties. Its population decline in nature has led to a vulnerable status, prompting conservation efforts, such as in vitro culture. Browning poses a significant challenge in the woody plant in vitro culture. Browning inhibitors such as ascorbic acid, activated charcoal and dark incubation can be used to address this issue.

This paper explores public reaction to a pseudoscientific earthquake prediction for the New Madrid Seismic Zone (NMSZ) that achieved wide dissemination between 1989–1990. The prediction originated with Iben Browning, holder of a Ph.D. in zoology, a business consultant, and a self-described climatologist (he had no formal training in the field). Browning claimed that conditions on or around December 3, 1990, would be “ripe” for a sizable earthquake in the NMSZ (as well as other areas around the world).

Major problems encountered in establishing axenic cultures are contamination and browning of explants and media. Contamination is initiated in explants excised from soil-borne tissues or adult trees. Several sterilizing agents (Tween 20, chlorine water, silver nitrate, mercuric chloride, etc.) or a wash in antibiotic solution are recommended to reduce this. . Establishing in vitro cultures of Acacia nilotica old tree nodal explants was a serious problem. The present study was undertaken to create a suitable protocol for in vitro micropropagation of nodal explants of Acacia nilotica subsp. indi

Obesity is a worldwide chronic metabolic disease characterized by an abnormal fat accumulation and represents one of the main risk factors for several diseases. White adipose tissue is the primary site for energy storage in the form of triglycerides, whereas brown adipose tissue does not store energy-providing lipids but rather dissipates it by producing heat. White-to-brown adipocyte trans-differentiation could represent a new target of anti-obesity strategies and result in fat reduction. Previous studies indicated that adenosine receptor activation induces trans-differentiation of white adip

Research for the development of protocols for the micropropagation of coconut plants (Cocos nucifera L.) has encountered several difficulties, such as explant browning. Although browning could be overcome by adding activated charcoal, this additive can also bind components of the culture medium required for the tissue morphogenic responses; this adsorption can be up to 99 % of the growth regulators added to the medium. In this work we developed a protocol without the use of activated charcoal which is able to produce embryogenic calli from coconut palm plumules as explants. This protocol also

Human adipose-derived stromal/stem cells (hASCs) are a promising tool to investigate the underlying mechanisms of such mitochondrial dysfunction and to subsequently provide knowledge for the development of treatments for obesity-related pathologies. A substantial obstacle in using hASCs is that the key compounds for adipogenic differentiation in vitro increase mitochondrial uncoupling, biogenesis, and activity, which are the sig

In addition to PGR, planting media is important for the growth of each plant. The planting media also has function as the root container, and the media which can absorb nutrient solution when it is doused or dripped. This research was conducted at The Greenhouse, Sukun Street
