What explains California? To a large extent, as Philip Fradkin's rich, exuberant portrait makes clear, it's the multiple landscapes and the different states of mind that best define America's most populous, diverse, and fabled state. Fradkin divides California into seven distinct ecological and cultural provinces--from the hot deserts and high peaks to the rich agricultural Central Valley, the redwood forests of the north and sandy beaches of the south. Describing geographical regions based on their emblematic landscape features, Fradkin intertwines natural and social history.
Author Notes
Philip Fradkin is the author of six highly acclaimed books on the American West, including the newly updated A River No More (California, 1996). A former environmental writer for the Los Angeles Times , he also served as Assistant Secretary of the California Resources Agency, as Western editor for Audubon magazine, and has taught nonfiction writing at Stanford and UC Berkeley. He shared in a Pulitzer prize awarded to the Los Angeles Times for coverage of the 1965 Watts racial conflict.
Reviews 2
Publisher's Weekly Review
In this ambitious and highly readable attempt to explain California, Fradkin (An American Nuclear Tragedy) reveals how the state's landscape has helped shape its destiny. Hanging his narrative on geological features of seven regions of the state (e.g., a series of dry lakes, a mountain, a lava bed, an earthquake fault), he puts heavy emphasis on California's violent past and present: the destruction of the Modoc Indians, anti-Chinese pogroms, the incarceration of Japanese Americans in WWII, the death of James Dean (``a California life, a California death, a California life after death''), a serial killer in Marin County, drive-by shootings so common they are no longer news. Into these and numerous other topics Fradkin weaves personal impressions of this richly textured land and its restless population acquired during his 35 years residing in the state. The vision throughout is distinctly negative. As to California's future, Fradkin sees it as ``a dark, chaotic time,'' a statement typical of this masterly but withering interpretation of the Golden State. (July) (c) Copyright PWxyz, LLC.

Choice Review
Nowhere in the US are contrasts in landscape more spectacular across short distances than in California. Fradkin, a journalist and environmentalist, illustrates this point through his assessment of the "Golden State" as a composite of seven radically different places, tied together by historical-political edict. The seven "states" are logical geographic subdivisions or regions, as estranged from one another as Death Valley is from the redwood groves of the northeast coast. Incorporating observations collected during decades of residence and a very broad range of secondary archival materials and original field interviews, Fradkin presents a portrait of each region in turn, often beginning with Native American cultures and the experience of Hispanic and Anglo contact, followed by a historical account of early settlement as a context for the evolution of present-day landscapes. Fradkin relates descriptions of each region to a specific settlement or area, so the reader learns, for example, the details of the Donner tragedy at the Sierra summit and that early white residents of Eureka were formidable racists who advocated murdering Indians and driving Chinese from the state. Compellingly written, with extensive source notes and monochrome photographs. Strongly recommended for libraries as a basic reference on the state. All levels. K. B. Raitz University of Kentucky

Sparkly Princess
I made an easel card so she could keep it displayed in her room. Now, for some of the details for you. I colored the image with copics and cut her out (honestly not sure why I cut it out though)and popped her up with foam tape. I added silver stickles to the tiara, stardust stickles to the gloves and dress, pink rhinestones to the crown, pearls in the shoe straps, and I sponged sky ink around her. All of the edges were distressed, sewn, and trimmed with stardust stickles.
Here is a close up of Princess Tilda
The beautiful rose flowers are from Wild Orchid Crafts and they too were accented with stickles. The pearl sprays are from Zva Creative. It is the first time that I have ever used them and I think I like lol. I will be needing more of those for sure- on the birthday list :)
The inside I decorated using Fancy Tags from Spellbinders and some silver sparkly stickers from my stash. I thought my daughter would really enjoy having it personalized with her name. I used ribbon, pearls, flowers, and stickles to keep uniformity in the card.
stamp- Magnolia Princess Tilda
paper- memory box and ctmh dp, Neenah white
accessories- Zva creative pearls, wild orchid flowers, copics, stardust and silver stickles, pink rhinestones, lace, pink satin ribbon, sewing machine, spellbinders fancy tags, lace doilly
Some awesome challenges that I am submitting my card for:
7 Kids College fund challenge- Flowers and layers
Wild Orchid Crafts- Pastels (light pink)
ABC challenge- flowers
Magnolia Stamp Lovers- Sparkling- definitely got this covered lol
Charisma Cardz- more than one fold (easel card, 2 folds)
Paper Sundaes- for someone little (my youngest daughter Lauren)
Tuesday throwdown- anything goes
Allsorts challenge- bingo (pearls, stickles, ribbon)
Our Creative Corner- Embellishments (use at least 3)

Alright alright…I admit it. I'm sick. You happy now? I'm freely admiting that I'm unwell. My head constantly feels like it's been used for a monotonous drumset and my throat feels like it's stuffed with some overinflated baloon that was made out of sandpaper. Definitely not the best way to go through the day.
Has anyone noticed KL has been pretty hot and humid it has been lately? It feels like a heat wave over here. But the current temperature it keeps registering is about 30 degrees celcius. So either I'm burning up…or the temperature meter is off by alot. That along with me being unwell is really starting to burn me up…heat is not good for a headache…which seems to be amplified the moment I step outside any air conditioned area. Then my head would feel like baker's dough…constantly kneeded and prodded by some unseen hands.
Many of you have asked why don't I see a doctor. Well here is my reason for it. Short of my illness killing me, there is no way I'm going to be given painkillers and antibiotics for something so minor like this. Minor you say? Yes…minor. I may have one constantly bad headache, but I don't have a fever. Which means my body doesn't really consider the infection to be worthwhile anyway. If I were to take whatever the doctor gave me…I could probably get it over the counter in a pharmacy.
Hell…didn't anyone tell you? Prolonged use of antibiotics tend to make any bacteria stronger in the long term…so it's taken when necessary…which probably means when I can't lift my arms to suck soup through a straw…
Then there is the whole going there and waiting and dignosis and waiting again and going home. It's just a big waste of time…or I'm too lazy to get off my butt to the clinic. Either way…I'm staying put on my bed.
So now, all I have to do is to sit and wait this one up. There is always something about an illness that makes you feel like it will last for the rest of your life. I wonder if anyone else has that feeling? You know…like when you lose your hearing in one ear…you tend to wonder will this be permanent? Or maybe that's just me I guess.
I guess the only thing left to do is to get some sleep. I promised someone I'd sleep early anyway. Let's just hope my air conditioning can keep me cool. Nothing like a headache in the middle of the night to ruin a good night's sleep.

Yes, I do smoke weed a lot of the time, because as I mentioned in my about section, it helps to keep me balanced, happy and focused, but alas, I'm not well versed in the art of joint rolling. That's ok, because it's 2017 and the world has so many options for us poor pathetic excuses for stoners. There's vapes, there's travel sized bongs, Pinterest for DIY bongs when you're in a pinch, the list goes on and on. But if you'd like to roll a joint and aren't able to do it the ol' fashion way, here's some products that you may find helpful.
Rolling Joint Machines
Keep in mind that even though I smoke, I am also new to a lot of cannabis practices that have been happening for ages. I'm not sure how long the RAW joint rolling contraption has been available, but I'm very happy I discovered it.
So I had a little trouble with this, but that's probably because I skimmed through the instructions because I hate instructions. I find my self skimming to get to the good part which usually leads me to the end and then I realize maybe I should just start over and actually read what it says.
But I didn't do any of that. I went on youtube because I'm a proud VISUAL learner and I like seeing how things are done versus reading about them.
"Why does the fucking raw tent material thingy keep coming up" is a question I asked myself over and over after each failed attempt. It was simple, I wasn't using enough flower. If you're a cheap bitch like myself you best throw caution into wind and build that shit up. This is not the time to start rationing shit out. The more you put the better I found the sleeve stayed in place without popping up.
I also brought some crutches, aka pre-rolled tip because I really don't like manual labor. It's not for me. Make sure to put that in before you add the flower as that's the CRUTCH of your joint (I'll be here all night.) After doing both steps bring the bottom wheel back into place and start rolling forward.
After rolling it and making sure the flower is packed tightly together in the shape of a cigarette, add paper. I licked both sides of the paper as it was sticking out from the rollers because I couldn't figure out which one to lick, making my joint loose. Like my vagina, I prefer my joints tight. Because nothing makes you feel more womanly than being able to crush a penis with the very part of your body that expels life. But you can't use yoni eggs for joints after they've been created so you're only left with the choice to do it right the first time.
Make sure to roll the paper in there for a good while to make sure joint is tightly wound. After that, bring the bottom part back down to open it and you'll find a beautiful joint waiting for your consumption.
Here's a short one minute video that should help you:
Maybe you don't want a joint rolling machine. Maybe you just can't with any extra steps and want the cone pre-made for you.Which brings me to RAW Cones. Omg, before I discovered vapes, this was my favorite go to for smoking. They're already ready to be packed with your strain of choice, and they even have a built in crutch. YASSSSSS!!!! COME THROUGH RAW!!!!
How to do it man I gave up on being manual along time when it came to joint rolling. I've actually given up on a lot of things but that's not really relevant. I will definitely try again in the future, but at this moment these practices suit me just fine. If you don't wanna embrace technology for the beautiful gifts it's bestowed upon us, that's totally fine. But I can't help you because I'm shit at rolling joints.

NEI •gU~1dH•11 ~1`-;' 1Iiffl' J11111 ! pt mllml•I~ •11 780 through tubes of micanite or specially prepared paper lining the slots; or with single-turn loops, stout bars of copper of U-shape can be driven through the slots and closed by soldered connexions at the other end. The first experimental determination of the shape of the E.M.F. curve of an alternator was made by J. Joubert in 1880. A revolving shape of contact-maker charged a condenser with the E.M.F. B.M.F. produced by the armature at a particular instant during curse. each period. The condenser was discharged through a ballistic galvanometer, and from the measured throw the instantaneous E.M.F. could be deduced. The contact-maker was then shifted through a small angle, and the instantaneous E.M.F. at the new position corresponding to a different moment in the period was measured; this process was repeated until the E.M.F. curve for a complete period could be traced. Various modifications of the same principle have since been used, and a form of " oscillograph " (q.v.) has been perfected which is well adapted for the purpose of tracing the curves both of E.M.F. and of current. The machine on which Joubert carried out his experiments was a Siemens disk alternator having no iron in its armature, and it was found that the curve of E.M.F. was practically identical with a sine curve. The same law has also been found to hold true for a smooth-core ring or drum armature, but the presence of the iron core enables the armature current to produce greater distorting effect, so that the curves under load may vary considerably from their shape at no load. In toothed armatures, the broken surface of the core, and the still greater reaction from the armature current, may produce wide variations from the sine law, the general tendency being to give the E.M.F. curve a more peaked form. The great convenience of the assumption that the E.M.F. obeys the sine law has led to its being very commonly used as the basis for the mathematical analysis of alternator problems; but any deductions made from this premiss require to be applied with caution if they are likely to be modified by a different shape of the curve. Further, the same alternator will give widely different curves even of E.M.F., and still more so of current, according to the nature of the external circuit to which it is connected. As will be explained later, the phase of the current relatively to the E.M.F. depends not only on the inductance of the alternator itself, but also upon the inductance and capacityofthe external circuit, so that the same current will produce different effects according to the amount by which it lags or leads. The question as to the relative advantages of differently shaped E.M.F. curves has led to much discussion, but can only be answered by reference to the nature of the work that the alternator has to do—i.e. whether it be arc lighting, motor driving, or incandescent lighting through transformers. The shape of the E.M.F. curve is, however, of great importance in one respect, since upon it depends the ratio of the maximum instantaneous E.M.F. to the effective value, and the insulation of the entire circuit, both external and internal, must be capable of withstanding the maximum E.M.F. While the maximum value of the sine curve is Al 2 or 1.414 times the effective value, the maximum value of a A curve is 1.732 times the effective value, so that for the same effective E.M .F. the armature wires must not only be more heavily insulated than in thecontinuouscurrent dynamo, but also the more peaked the curve the better must be the insulation. Since an alternating current cannot be used for exciting the field-magnet, recourse must be had to some source of a direct Exalts- current. This is usually obtained from a small auxiliary don. continuous-current dynamo, called an exciter, which may be an entirely separate machine, separately driven and used for exciting several alternators, or may be driven from the alternator itself ; in the latter case the armature of the exciter is often coupled directly to the rotating shaft of the alternator, while its field-magnet is attached to the bed-plate. Although separate excitation is the more usual method, the alternator can also be made self-exciting if a part or the whole of the alternating current is " rectified," and thus converted into a direct current. The general idea of the polyphase alternator giving two or more E.M.F.'s of the same frequency, but displaced in phase, has been Quarter already described. The several phases may be entirely phase independent, and such was the case with the early poly- alter- phase machines of Gramme, who used four independent =tom. circuits, and also in the large two-phase alternators designed by J. E. H. Gordon in 1883. If the phases are thus entirely separate, each requires two collector rings and two wires to its external circuit, i.e. four in all for two-phase and six for three-phase machines. The only advantage of the polyphase machine as thus used is that the whole of the surface of the armature core may be efficiently covered with winding, and the output of the alternator for a given size be thereby increased. It is, how-ever, also possible so to interlink the several circuits of the armature that the necessary number of transmitting lines to the external circuits may be reduced, and also the weight of copper in them for a given loss in the transmission.' The condition which obviously ' As in the historical transmission of energy from Lauffen to Frankfort (1891).must be fulfilled, for such interlinking of the phases to be possible, is that in the lines which are to meet at any common junction the algebraic sum of the instantaneous currents, reckoned as positive if away from such junction and as negative if towards it, must be zero. Thus if the phases be diagrammatically represented by the relative angular position of the coils in fig. 39, the current in the coils A and B differs in phase from the current in the coils C and D by a quarter of a period or 90°; hence if the two wires b and d be replaced by the single wire bd, this third wire will serve as a common path for the currents of the two phases either outwards or on their return. At any instant the value of the current in the third wire Fin. 39. must be the vector sum of the two currents in the other wires, and if the shape of the curves of instantaneous E.M.F. and current are identical, and are assumed to be sinusoidal, the effective value of the current in the third wire will be the vector sum of the effective values of the currents in the other wires; in other words, if the system is balanced,the effective current in the third wire is,/ 2, or 1.414 times the current in either of the two outer wires. Since the currents of the two phases do not reach their maximum values at the same time, the sectional area of the third wire need not be twice that of the others; in,order to secure maximum efficiency by employin the same current density in all three wires, it need only be 40 ° greater than that of either of the outer wires. The effective voltage between the external leads may in the same way be calculated by a vector diagram, and with the above star connexion the voltage between the outer pair of wires a and c is sl 2, or 1.414 times the voltage between either of the outer wires and the common wire bd. Next, if the four coils are joined up into a continuous helix, just as in the winding of a continuous-current machine, four wires may be attached to equidistant points at the opposite ends of two diameters at right angles to each other (fig. 40). Such a method is known as the mesh connexion, and gives a perfectly symmetrical four-phase system of distribution. Four collecting rings are necessary if the arma- FIG. 40. ture rotates, and there is no saving in copper in the transmitting lines; but the importance of the arrangement lies in its use in connexion with rotary converters, in which it is necessary that the winding of the armature should form a closed circuit. If e =the effective voltage of one phase A, the voltage between any pair of adjacent lines in the diagram is e, and between m and o or n and p is e 42. The current in any line is the resultant of the currents in the two phases connected to it, and its effective value is c Alt, where c is the current of one phase. When we pass to machines giving three phases differing by 120°, the same methods of star and mesh connexion find their analogies. If the current in coil A (fig. 41) is flowing away from the centre, and has its maximum value, the currents in coils B and C are flowing towards the centre, and are each of half the magnitude of the current in A; the algebraic sum of the currents is therefore zero, and this will also be the case for all other instants. Hence the three coils can be united together at the centre, and three external wires are alone required. In this star or "Y " connexion, if e be the effective voltage of each phase, or the voltage between any one of the three collecting rings and the common connexion, the volts between any pair of transmitting lines will be E = e 11 3 (fig. 41) ; if the load be balanced, the effective current C in each of the three lines will be equal, and the total output in watts will be W=3Ce 3CE// 3 =1.732 EC, or 1.732 times the product of the effective voltage between the lines and the current in any single line. Next, if the three coils are closed upon themselves in a mesh or delta fashion (fig. 42), the three transmitting wires may be connected to the junctions of the coils (by means of collecting rings if the armature rotates). The voltage E between any pair of wires is evidently Three-phase alternators. that generated by one phase, and the current in a line wire is the resultant of that in two adjacent phases; or in a balanced system, if c be the current in each phase, the current in the line wire beyond a collecting ring is C=cal 3, hence the watts areW=3cE=3CE/ /3 =1.732 EC, as before. Thus any three-phase winding may be changed over from the star to the delta connexion, and will then give 1.732 times as much current, but only I/1•732 times the voltage, so that the output remains the same. The " armature reaction " of the alternator, when the term is used in its widest sense to cover all the effects of the alternating Armature current in the armature as linked with a magnetic circuit or circuits, may be divided into three items which are reaction inalfery different in their origin and consequences. In the first nators. place the armature current produces a self-induced flux in local circuits independent of the main magnetic circuit, as e.g. linked with the ends of the coils as they project outwards from the armature core; such lines may be called " secondary leakage," of which the characteristic feature is that its amount is independent of the position of the coils relatively to the poles. The alternations of this flux give rise to an inductive voltage lagging 90° behind the phase of the current, and this leakage or reactance voltage must be directly counterbalanced electrically by an equal component C in the opposite sense in the voltage from the main field. The second and third elements are pendent upon the position of the coils in relation to the poles and in relation to the phase of the current which they then carry. When the side of a drum coil is immediately under the centre of a pole, its ampere-turns are cross-magnetizing, i.e. produce a distortion of the main flux, displacing its maximum density to one or other edge of the pole. When the coil-side is midway between the poles and the axes of coil and pole coincide, the coil stands exactly opposite to the pole and embraces the same magnetic circuit as the field-magnet coils; its turns are therefore directly magnetizing, either weakening or strengthening the main flux according to the direction of the current. In intermediate positions the ampere-turns of the coil gradually pass from cross to direct and vice versa. When the instantaneous values of either the cross or direct magnetizing effect are integrated over a period and averaged, due account being taken of the number of slots per coil-side and of the different phases of the currents in the polyphase machine, expressions are obtained for the equivalent cross and direct ampere-turns of the armature as acting upon a pair of poles. For a given winding and current, the determining factor in either the one or the other is found to be the relative phase angle between the axis of a coil in its position when carrying the maximum current and the centre of a pole, the transverse reaction being proportional to the cosine of this angle, and the direct reaction to its sine. If the external circuit is inductive, the maximum value of the current lags behind the E.M.F. and so behind the centre of the pole; such a negative angle of lag causes the direct magnetizing turns to become back turns, directly weakening the main field and lowering the terminal voltage. Thus, just as in the continuous-current dynamo, for a given voltage under load the excitation between the pole-pieces X" must not only supply the net excitation required over the air-gaps, armature core and teeth, but must also balance the back ampere-turns Xe of the armature. Evidently therefore the characteristic curve connecting armature current and terminal volts will with a constant exciting current depend on the nature of the load, whether inductive or non-inductive, and upon the amount of inductance already possessed by the armature itself. With an inductive load it will fall more rapidly from its initial maximum value, or, conversely, if the initial voltage is to be maintained under an increasing load, the exciting current will have to be increased more than if the load were non inductive. In practical working many disadvantages result from a rapid drop of the terminal E.M.F. under increasing load, so that between no load and full load the variation in terminal voltage with constant excitation should not exceed 15 %. Thus the output of an alternator is limited either by its heating or by its armature reaction, just as is the output of a continuous-current dynamo; in the case of the alternator, however, the limit set by armature reaction is not due to any sparking at the brushes, but to the drop in terminal voltage as the current is increased, and the consequent difficulty in maintaining a constant potential on the external circuit. The joint operation of several alternatots so that their outputs may be delivered into the same external circuit is sharply dis-The tinguished from the corresponding problem in continuous-coupling current dynamos by the necessary condition that they of alter- must be in synchronism, i.e. not only must they be so nators. driven that their frequency is the same, but their E.M.F.'s must be in phase or, as it is also expressed, the machines must be in step. Although in practice it is impossible to run two alternators in series unless they are rigidly coupled together—which virtually reduces them to one machine—two or more machines can be run in parallel, as was first described by H. Wilde in 1868 and subsequently redemonstrated by J. Hopkinson and W. G. Adams in 1884. Their E.M.F.'s should be as nearly as possible in synchronism, but, as contrasted with series connexion, parallel coupling gives them a certain power of recovery if they fall out of step, or are not in exact synchronism when thrown into parallel. In such circumstances a synchronizing current passes between the two machines, due to the difference in their instantaneous pressures; and as this current agrees in phase more nearly with the leading than with the lagging machine, the former machine does work as a generator on the latter as a motor. Hence the lagging machine is accelerated and the leading machine is retarded, until their frequencies and phase are again the same. The chief use of the alternator has already been alluded to. Since it can be employed to produce very high pressures either directly or through the medium of transformers, it is specially adapted to the electrical transmission of alte Usesrvoz energy over long distances.' In the early days of nator, electric lighting, the alternate-current system was adopted for a great number of central stations; the machines, designed to give a pressure of 2000 volts, supplied transformers which were situated at considerable distances and spread over large areas, without an undue amount of copper in the transmitting lines. While there was later a tendency to return to the continuous current for central stations, owing to the introduction of better means for economizing the weight of copper in the mains, the alternating current again came into favour, as rendering it possible to place the central station in some convenient site far away from the district which it was to serve. The pioneer central station in this direction was the Deptford station of the London Electric Supply Corporation, which furnished current to the heart of London from a distance of 7 M. In this case, however, the alternators were single-phase and gave the high pressure of Io,000 volts immediately, while more recently the tendency has been to employ step-up transformers and a polyphase system. The advantage of the latter is that the current, after reaching the distant sub-stations, can be dealt with by rotary converters, through which it is transformed into a continuous current. The alternator is also used for welding, smelting in electric furnaces, and other metallurgical processes where heating effects are alone required; the large currents needed therein can be produced without the disadvantage of the commutator, and, if necessary, transformers can be interposed to lower the voltage and still further increase the current. The alternating system can thus meet very various needs, and its great recommendation may be said to lie in the flexibility with which it can supply electrical energy through transformers at any potential, or through rotary converters in continuous-current form.

The Centers for Disease Control and Prevention estimate that up to 6 million people throughout the United States are living with atrial fibrillation, or AFib. This form of irregular heartbeat dramatically increases your parent's risk of suffering serious health conditions, including stroke and heart attack. As a family caregiver, it is important that you understand the risks that can increase the possibility that your parent will experience this condition, including the health conditions and complications that can contribute to AFib.
Some of the health conditions that can contribute to AFib include:
- High blood pressure, particularly high blood pressure that is not well controlled
- Sleep apnea
- Thyroid disease
- Diabetes
- Chronic lung disease
- History of heart attack
- Heart valve disease
- Heart failure
- Chronic lung disease
- Obesity
If your parent is dealing with any of these conditions, particularly if they also have other risk factors for atrial fibrillation such as family history or a personal history of drinking, talk to your parent's doctor about their risk and what you can do to help them reduce the risk of developing this condition.
Controlling their medical conditions and challenges can help to reduce the impact of these risk factors, both in terms of reducing the risk that your parent will develop AFib, but also the severity of it and how it impacts their health.
For example, if your aging parent is living with high blood pressure, ensuring that they are following with instructions that their doctor gave them and remaining compliant with their medications will help to reduce the chances that they will develop AFib, but it will also help to reduce the chances that they will suffer a stroke or heart attack should they develop this condition.
If you have been looking for ways to enhance your parent's quality of life, ensure that they get all of the care and support that they need, and encourage them to maintain as much independence and fulfillment as possible as they age in place, starting homecare for them may be the ideal choice.
