Seems like calcium and phosphorus gather up all the attention, but there is growing awareness of the importance of magnesium – the “runner up mineral” in the dairy cow diet. Some sources of magnesium are simply more available than others. This fact has the ignited the interest of ruminant nutritionists looking to focus their research efforts on determining the most available Mg source so you can get the biggest bang for your buck. This month we featured an article from Dr. Noelia Silva Del Rio, from UC Davis. She describes her research on the rumen availability of different popular magnesium sources and explains the importance of magnesium and how to improve the mineral status of your herd.

In this short podcast episode, Bryan gets into some oil talk, covering some common refrigerant oil terms and types. Esterification is the process by which organic acid and alcohol come together to form polyolester (POE) oil and water. Hydrolysis refers to the decomposition of a substance when it comes into contact with water; when POE mixes with water, it will break down into esters, organic acids, and alcohol. Once POE oil undergoes hydrolysis, the process can't be reversed to get the same original oil. POE oil is also hygroscopic; hygroscopicity refers to the ability of the oil to absorb moisture. Miscibility refers to the ability of an oil to mix with refrigerant and be carried with it. In the context of refrigerant oil, "polar" refers to a molecular structure with an uneven distribution of electrons; oils with polar structures attract water molecules. Solubility refers to how well one compound can dissolve into another. Mineral oil is a product of the distillation of crude oil and was common in systems that used CFC and HCFC refrigerants. Mineral oil isn't as miscible with new refrigerants that lack a chlorine molecule. Alkylbenzene (AB) is a synthetic oil used in some commercial refrigeration systems that is compatible with mineral oil. Polyolester (POE) oil is one of the most common synthetic oils we use in systems that use HFC refrigerants; its main downside is its high hygroscopicity and tendency to undergo hydrolysis. Polyalkylene glycol (PAG) oil is common in automotive A/C systems (R-134A) and is more hygroscopic than POE oil but does not undergo hydrolysis. Polyvinyl ether (PVE) oil is used as an alternative to POE oil; it is more hygroscopic but does not undergo hydrolysis.   Learn more about the HVACR Training Symposium or buy a virtual ticket today at https://hvacrschool.com/symposium.

Abstract: The immediate molecular consequences of traumatic brain injuries or TBI are poorly understood. Here, we simulated TBI using an innovative laboratory apparatus that employs a 5.1 kg dummy head holding neuronal cells and generating a less than or equal to 4,000 g-force acceleration upon impact. Dynamic impact led to both reduction in neuron viability and massive solubility changes in the proteome profiled using Proteome Integral Solubility Alteration (PISA) assay. The affected proteins mapped not only to the expected pathways like cell adhesion, collagen and laminin structures, as well as response to stress, but also to other dense protein networks, such as immune response, complement and coagulation cascades. The cellular effects are found to be mainly due to the shockwave rather than the g-force acceleration. Soft materials could reduce the impact severity only until being fully compressed. This study shows way to develop a proteome-based meter for measuring irreversible shockwave-induced cell damage and provides a resource for identifying TBI protein biomarkers and potential drug targets for developing products aiming at primary prevention and intervention.

In this issue, discover how nanomilling can improve the solubulity and bioavailability of your drug. Click here to download a PDF, readable version of Issue 22: https://www.altasciences.com/sites/default/files/2022-02/The-Altascientist_issue-22_Nanomilling.pdf A crucial feature of drug development is bioavailability, defined as “the ability of a drug to be absorbed and used by the body.” For a drug to be bioavailable, it must first be soluble, meaning able to be dissolved, especially in water. Many drugs on the market today are poorly water soluble, and patent extensions or 505(b)(2) new patents become possible for formulation improvements delivered via nanomilling.

When making cannabis foods & beverages, water solubility is a very important consideration with regards certainly to beverages, but also when one is seeking to deliver speed and consistency of absorption and effect.  Keith Woelfel, R&D Director at Stillwater Brands and a 20+ year veteran of Mars/Wrigley joins us to discuss.  

Our episode starts with addressing the question: What IS solubility? (1:19). The episode introduces solubility equilibria with respect to the Solubility-Product Constant, K, expression (1:57) and discussion how its magnitude relates to solubility (3:05). If you have the Ksp you can calculate the molar solubility - in mol/L - as well as the mass solubility in g/L (4:35). Comparing K to Q let’s you determine if a precipitate forms (5:58).Question: How does a common ion affect the solubility of a salt?Thank you for listening to The APsolute RecAP: Chemistry Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.

Our listener’s choice recaps three topics: Ideal Gas Laws, Solubility and Internal Energy.We start by recapping what an ideal gas is compared to a real gas (1:28) and review the equation PV=nRT by describing the relationship between selected variables (2:11). We take a closer look at the relationship between particle number and pressure and review partial pressures (3:02). In our solubility recap we review the polarity of the water molecule (4:55) as well as discuss how polarity and intermolecular forces affect solubility and miscibility (5:22). Our third topic starts by defining internal energy (6:17), how the change is calculated (6:41) and the terms exothermic and endothermic (7:06).Question: Which of the following compounds would be most soluble in H2O?

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.09.276915v1?rss=1 Authors: Kuriata, A., Badaczewska-Dawid, A., Pujols, J., Ventura, S., Kmiecik, S. Abstract: Protein aggregation is a major hurdle in the development and manufacturing of protein-based therapeutics. Development of aggregation-resistant and stable protein variants can be guided by rational redesign using computational tools. Here, we describe the architecture and functionalities of the Aggrescan3D (A3D) standalone package for the rational design of protein solubility and aggregation properties based on three-dimensional protein structures. We present the case studies of the three therapeutic proteins, including antibodies, exploring the practical use of the A3D standalone tool. The case studies demonstrate that protein solubility can be easily improved by the A3D prediction of non-destabilizing amino acid mutations at the protein surfaces.

When talking about chemistry, one of the first topics to breach is the chemistry of soap. In the time of a global pandemic, washing our hands has become second nature and at some point at the beginning the stockpiling of soap even led to shortages in some areas. So let's talk about soap and how it does its job. Sources https://de.wikipedia.org/wiki/Seife https://en.wikipedia.org/wiki/Soap General Chemistry by D. D.

Wenn man über Chemie redet, dann ist eines der ersten Themen, die immer aufkommen die Chemie von Reinigungsmitteln und Seifen. In der heutigen Zeit in der eine globale Pandemie die Welt in Atem hält, wurde Hände waschen zu einem natürlichen Reflex. Anfangs gab es sogar Momente in dem das Hamstern von Seife in manchen Teilen der Welt zu Knappheiten führte. Deswegen, sprechen wir doch heute einmal über Seife und wie diese wirkt.

Perhaps because “alkaline” and “alkalinity” are such similar words, pH and alkalinity are often confused and misunderstood. Indeed they are related to one another, but they are not the same. In water chemistry we test alkalinity because it serves as the buffer of pH fluctuations. Too much alkalinity is a source of rising pH, and too little means that pH corrections can be too extreme, leading to pool damage and other costly problems. pH itself is the “power of Hydrogen”, an equilibrium of Hydrogen (H+) and Hydroxides (OH-), on a logarithmic scale of 0-14. 7 is perfectly neutral pH, with 50% Hydrogen, and 50% Hydroxide. When pH rises, more Hydrogen dissociates from a given substance (like chlorine, or bicarbonate alkalinity) making it more basic, or alkaline. When pH is lower, more Hydrogens reattach or bind to a given substance, making it more acidic.  This episode explains all these nuances and gives real-world examples in pool chemistry.Show-Notes: [01:32] What is ph?[02:30] pH is an equilibrium[07:58] Negative logarithm of hydrogen[08:43] Let's not try to control pH.

EPISODE: 012 The Dial in is DEAD! … Roasting for Solubility, Cuppings: it’s not the size that counts, Goodbye African coffees. This week we thought we’d finally flesh out a big part of why we do what we do - Roasting for solubility. How it saves you time, money and stress every single day. We had a such a great Tuesday cupping with the crew from Bayleaf cafe, an awesome turn out with beginners, veterans and lots of interaction and love from both sides. It’s big job to get the most part of your staff all in one place at one time whilst keeping the cafe operating, so big ups Bayleaf manager, Jesse. On that note, don’t feel like they need to be a party. If you just wanna show up slurp 8 bowls on your way into town and bail, thats cool too! As always we finish off with a menus update, This week we roasted the very last of the African coffees  and some beautiful new Colombians arrived courtesy of Caravela. I think theres a fairly deep tangent on Joe’s super human marathon training regime too.

Q. How does Soil Deficiency affect what we eat in the Plant kingdom?  A.  Don explains a little bit about the history behind this, the 20 year Experiment they did and points out the false information given.  Plants don't eat dirt.  They Synthesise from Sunlight and the uptake of Solubility of Water, and they synthesise everything they need. They make Iron, Magnesium and everything they need from sunlight and water. It's not the dirt they eat.  There are organisms in the dirt that stimulate Electrical Force that can assist it to grow.  Water Mineralises itself from Sunshine, as do Plants and Humans.  It's like Parasites in our Body are not the problem, their there to clean up the Rot, Decay and Crud that there feeding and breeding in. The rot and decay are the problem. Through Fasting and other things, the parasites will leave because they don't like the Environment. In 1998 a Published study in USA alone, identified over 26,000 kinds of dirt. They found out that every kind of dirt doesn't want to grow what you decide to plant in it.  Therefore, if something you plant doesn't grow, move it to another place, it will most likely be another type of dirt and it should grow just fine.  To find out more, jump in and do some studies about the New Soil Sciences. Q.  How do we avoid Dental work and Root Canals?  A.  If it's a minor tooth ache use Essential Clove Oil (a natural analgesic) put it in the palm of your hand, rub it and put it on the gum and around the tooth. One of the biggest problems with Tooth Enamel and Receding Gums is brushing your Teeth.  So stop brushing your teeth. According to the Principles of Natural Dentistry you should take a cotton cloth, put the cloth around your finger, wet it, then rub Vegetable Glycerin soap on it, wash your teeth and tongue with it then rinse it out.  If it's something more serious, like you need a Root canal, search Google for Natural Dentistry (dentists who understand the teeth and it's relationship to the Spine and the Brain) and they can answer the questions that you have.  Q. With having Ulcerative Colitis in the large Intestine, what can you eat that isn't harsh on the system and what do you recommend for high Mercury Toxicity?  A.  The best way to go is making 60-70% of your diet Fermented foods. Buy any kind of Mucilaginous foods, things like Whole Flaxseed and Okra. Add Extra Virgin Oil to everything you are eating so the oil is used as a lubricant that is Nutritional. Salt will also correct the Lesions and Ulcerations. Each morning drink   1L of Water with 1 heaped tablespoon of Sea salt. Eat Raw food that is smooth, without a lot of fibre which can also help to alleviate the condition. Add olive oil, salt and lemon juice to high fibre content foods.  In 2-3weeks you will be more comfortable and Healing will take place. There's a meal that targets Ulcerative Colitis and Prostate Cancer.  Eat this meal every morning for breakfast: Prepare the night before - 2 cups of un-cooked rolled Oats, 1 tablespoon of Flaxseed and 1 tablespoon of Wheatgerm and squeeze Lemon juice on top of it.  The next morning add a little Apple juice or Organic Milk to moisten it before eating. By doing this you can typically Remise the problem within about 90days.  To help further remise, eat 2-3 handfuls of Raw Brazil Nuts everyday. Brazil Nuts have a Nutritional Component, called Selenium, and they have the highest Naturally occurring Selenium of any nut or seed they have ever studied. A young man fights to figure out what's best for his brothers future health and well being.  Don explains that you "Can not Serve Two Masters" as you are going to create a constant Chaos.  There can only be one path. It is a choice he gets to make. A principle of the ancient world was 'The First shall be Last, and the Last should be First'.  This is how Disease comes upon you and how it Remises.  It's a Truest Truth, that's the way it is. If you have a Lesion, Ulcer or bed sore, put Salt or Raw Honey on the wound and it will Heal everything up and be gone within 1 month. The problem is that Truth that is Free has little to no Value to most people. Unless you pay for it you don't think your getting value.

The solubility of Ni in a silicate melt has been measured using a new, mechanically assisted equilibration technique over a wide range of controlled ƒO2 values. The melt composition corresponds to the 1 atm eutectic in the system CaAl2Si2O8-CaMgSi2O6 + 10 wt% CaO. The experiments were performed at 1300°C and over an ƒO2 range of 10−8.5 to 10−13.75, and over a temperature range of 1270 to 1390°C at a constant gas mixing ratio ( ). The experiment consists of a sample of melt contained within a crucible of Ni metal and held in a 1 atm gas mixing furnace. A Ni spindle is entered into the sample from above and continuously rotated at a constant angular velocity using a viscometer head. The stirring of the sample serves to accelerate the approach to equilibrium between the liquid sample and the metal crucible (and spindle). This arrangement allows relatively rapid equilibration of Ni content following changes to higher or lower ƒO2 values. Samples of the melt may be taken at any time for analysis and thus the equilibrium solubility of Ni in the silicate melt may be determined from unambiguous experimental reversals. The Ni contents of samples, analysed both by INAA and by ICP-AES, range from 25 to 5300 ppm. The data presented in this paper indicate that the oxidation state of Ni in the investigated melt is Ni2+ over the entire range of ƒO2 investigated. This conclusion contrasts with recent reports in the literature of an inflection in the ƒO2 dependence of Ni solubility, which has been interpreted as solution of neutral Ni at low ƒO2 (Morse et al., 1991; Colson, 1992; Ehlers et al., 1992). We also present data for the temperature dependence of Ni solubility in the investigated melt. The solubility decreases with increasing temperature at constant ƒO2. The present results are in good agreement with the metal-loop-equilibration experiments reported by Holzheid et al. (1994).

The effects of F, B2O3 and P2O5 on the H2O solubility in a haplogranite liquid (36 wt. % SiO2, 39 wt. % NaAlSi3O8, 25 wt. % KAlSi3O8) have been determined at 0.5, 1, 2, and 3 kb and 800, 850, and 900°C. The H2O solubility increases with increasing F and B content of the melt. The H2O solubility increase in more important at high pressure (2 and 3 kb) than at low pressure (0.5 kb). At 2 kb and 800°C, the H2O solubility increases from 5.94 to 8.22 wt. % H2O with increasing F content in the melt from 0 to 4.55 wt. %, corresponding to a linear H2O solubility increase of 0.53 mol H2O/mol F. With addition of 4.35 wt. % B2O3, the H2O solubility increases up to 6.86 wt. % H2O at 2 kb and 800°C, corresponding to a linear increase of 1.05 mol H2O/mol B2O3. The results allow to define the individual effects of fluorine and boron on H2O solubility in haplogranitic melts with compositions close to that of H2O-saturated thermal minima (at 0.5–3 kb). Although P has a dramatic effect on the phase relations in the haplogranite system, its effect on the H2O solubility was found to be negligible in natural melt compositions. The concominant increase in H2O solubility and F can not be interpreted on the basis of the available spectroscopic data (existence of hydrated aluminofluoride complexes or not). In contrast, hydrated borates or more probably boroxol complexes have been demonstrated in B-bearing hydrous melts.

The compositional dependence of H2O solubility was investigated at 2 kbar and 800°C in haplogranite melts (system SiO2---1bNaAlSi3O8---1bKAlSi3O8 or Qz---1bAb---1bOr). The sixteen investigated compositions contained 25, 35 or 45 wt.% normative Qz and various Ab/(Ab+Or) ratios (0.15–0.92). Starting solid materials were anhydrous bubble-free glasses to which 10 wt.% H2O was added. The H2O contents of the isobarically quenched melts (glasses) were measured by Karl-Fischer titration. The results show that H2O solubility in aluminosilicate melts depends significantly upon anhydrous composition. The highest solubility values are obtained for the most Ab-rich melts. At a constant normative quartz content, the solubility of water decreases from 6.49 ± 0.20 wt.% H2O for a composition Qz35Ab60Or05 (normative composition expressed in wt.%) to 5.50 ± 0.15 wt.% H2O for a composition Qz35Ab10Or55. Along this join, the most significant changes are observed for Ab-rich melts whereas H2O solubility in Or-rich melts remains almost constant. The H2O solubility data imply that H2O is preferentially associated with the Ab component in aluminosilicate melts. Application of the results to natural granitic melts suggests that Na-rich, H2O-saturated melts may be significantly less viscous than H2O-saturated, K-rich melts. The temperature dependence of H2O solubility, investigated for composition Qz28Ab38Or34 at 2 kbar, is low. Increasing temperature from 750° to 1150°C only causes a decrease in H2O solubility from 6.00 to 5.41 wt.% H2O. These data are in agreement with previous data obtained for albite melts.
