In this study, different methods for shell splitting and the effect of freezing prior to drying on shell splitting percentage of pistachio were investigated. A completely randomized design was used to investigate the effects of different freezing temperatures (0, -6, -12 and -18°C), different drying temperatures (80, 90 and 100°C) and different cultivars (Akbari and Kalehghouchi) on shell split...

Background: This paper considers whether the development of oocyte freezing raises any new or distinctive ethical issues. It will examine the ethical issues raised by this technique: the ’social’ use of egg freezing and how that might be defined; the use of egg freezing for cancer patients; and limitations and benefits of the technique. Materials and Methods: A consideration of the literature a...

BACKGROUND Intracytoplasmic Sperm Injection (ICSI) is an Assisted Reproduction Technique (ART) which offers the chance to conceive to patients presenting very low sperm counts (cryptozoospermia/severe oligozoospermia). Sperm freezing before the oocyte pick-up, can prevent from a lack of spermatozoa on the day of the ICSI. It can avoid the cancellation of the ICSI or the use of TESE (Testicular ...

BACKGROUND Urinary albumin detection by immunonephelometry is decreased by approximately 30% in samples that have been frozen at -20 degrees C. An HPLC method for assessment of urinary albumin that detects immunoreactive and immunochemically nonreactive albumin has been introduced as an alternative to immunonephelometry. We investigated whether this technique is affected by sample temperature, ...

In this study, we compared the effects of repeated freezing/thawing of human sperm by our in-house method of rapid freezing with slow programmable freezing. Sperm samples from 11 normozoospermic subjects were processed through density gradients and divided into three aliquots: non-frozen, rapid freezing and slow programmable freezing. Sperm in the rapid freezing group had better motility and vi...

depth of frost penetration is one of the main indices in agriculture, civil and transportation engineering. soil temperature is a function of several factors including: topography, solar radiation, air temperature, moisture content and other physical properties of soil such as thermal capacity, coefficient of heat conductivity, and specific heat. the main objective of the present paper is to de...

Arabidopsis thaliana (L.) Heynh. has been described as a freezing-tolerant species based on freezing-resistance assays. Nonetheless, this type of experiment does not discriminate between freezing-tolerance and freezing-avoidance mechanisms. The purpose of this paper was to determine which of these two freezing-resistance mechanisms is responsible for freezing resistance in A. thaliana. This was...

At the advanced stage of Parkinson’s disease, patients may suffer from ‘freezing gait’ episodes: a debilitating condition wherein patient’s “feet feel as though they are glued to floor.” The objective, continuous monitoring gait disease with wearable devices has led development many freezing detection models involving automatic cueing rhythmic auditory stimulus shorten or prevent episodes. use ...

Nanoparticle formulations have been widely used in the drug delivery field. The majority of published articles dealing with nanoparticle formulations have focused on the use of freshly prepared nanoparticles, but not many deal with scale-up production of nanoparticles and their long-term preservation by freeze-drying. To date, little information is available on an effective freeze-drying proces...

purpose of this study is analysis of spatial auto-correlation of freezing changes of iran over the last half century. daily temperature data over the period 1340 - 1383 of esfezari database provided by doctor masoodian (to enhance the temporal resolution of the database, daily observations of temperature from 1383 to the end of 1390 using the same method and the same spatial resolution is added...
