La Serra morenica di Ivrea (o più semplicemente Serra d'Ivrea) è un rilievo morenico di origine glaciale risalente al periodo quaternario; appartiene al vasto complesso dell'Anfiteatro morenico di Ivrea.
Non va considerata come collina morenica, è infatti una montagna da considerare come tale.

Si estende dal territorio di Andrate (in provincia di Torino) fino alle porte di Cavaglià (in provincia di Biella), Alice Castello e Borgo d'Ale (in provincia di Vercelli) ed è la più grande formazione del genere esistente in Europa.

Caratteristiche

La Serra ha origine sulle pendici meridionali della Colma di Mombarone (2.371 m) e si dirige con percorso quasi rettilineo verso sud-est per circa 20 km fino a sfrangiarsi nelle alture che circondano il Lago di Viverone.

È costituita da una serie di creste sub-parallele la più alta delle quali raggiunge un dislivello massimo di 600 metri rispetto alla pianura interna all'anfiteatro morenico nella zona di Andrate. Questo dislivello si riduce gradualmente verso est fino a toccare i 250 metri circa nei pressi di Zimone. La cresta principale si situa al confine tra la Provincia di Torino e quella di Biella; tra i cordoni morenici che la fiancheggiano in territorio Biellese scorrono alcuni corsi d'acqua i più rilevanti dei quali sono i torrenti Olobbia e Viona, entrambi tributari dell'Elvo.

La zona ai piedi della Serra è ricca di laghi di origine glaciale. I principali sono il lago di Viverone, quello di Bertignano e il gruppo dei cinque laghi, il più vasto dei quali è il Sirio. Qualche piccolo specchio d'acqua si trova anche tra i cordoni morenici della Serra, come lo Stagno di Prè.

Storia
La Serra si è formata durante il pleistocene (fase glaciale che viene suddivisa dalla letteratura tradizionale (ripresa in Francani, 1997) in Mindel, Riss e Würm). Testimonianze di questi eventi glaciali sono ben evidenti nel Canavese sotto forma di depositi glaciali e fluvio-glaciali.

La lingua glaciale ed il relativo cordone morenico che maggiormente si spinse verso sud fu quello mindeliano. In particolare ci si riferisce all'anfiteatro morenico di Ivrea, che si sviluppa a nordest dell'area interessata dalla formazione, dove sono ben evidenti le varie pulsazioni glaciali che hanno prodotto imponenti accumuli morenici e appunto tra questi si segnala la Serra di Ivrea (morena laterale sinistra del ghiacciaio della Valle d'Aosta) che ha il suo omologo nei rilievi di Bairo ed Agliè, di forma meno regolare.

Tutela naturalistica
Buona parte della Serra morenica è inclusa in un sito di interesse comunitario denominato Serra di Ivrea (cod.IT1110057) della Regione Piemonte, designato inoltre come Zona Speciale di Conservazione. La zona della Serra costituisce inoltre un Geosito.

Hyperbolic metamaterials (HMMs) have recently garnered much attention because they possess the potential for broadband manipulation of the photonic density of states and subwavelength light confinement. These exceptional properties arise due to the excitation of electromagnetic states with high momentum (high-k modes). However, a major hindrance to practical applications of HMMs is the difficulty in coupling light out of these modes because they become evanescent at the surface of the metamaterial. Here we report the first demonstration, to our knowledge, of simultaneous spontaneous emission enhancement and outcoupling of high-k modes in an active HMM using a high-index-contrast bullseye grating. Quantum dots embedded inside the metamaterial are used for local excitation of high-k modes. This demonstration could pave the way for the development of photonic devices such as single-photon sources, ultrafast LEDs, and true nanoscale lasers.

Control of spontaneous emission (SE) is of both fundamental and technological importance. Conventional approaches to enhance SE by modifying the dielectric environment relies on resonant phenomena such as cavity resonance where the SE rate is enhanced over a narrow spectral range. Introducing an outcoupling mechanism then reduces the quality factor of the cavity and thereby the enhancement in SE rate. For applications requiring narrow wavelength response, photonic crystal cavities have been used to enhance emission by optimizing the structural parameters for directional emission and maximizing the Q factor for a given cavity mode [1,2]. An alternate approach that has recently attracted much attention is the use of hyperbolic metamaterials (HMMs) where the Purcell enhancement stems from high-momentum states called high-k modes, which exist in a broad spectral range and are a nonresonant phenomenon [3,4].
HMMs are artificially engineered substructured materials so named for possessing hyperbolic dispersion. HMMs in optical frequencies can be realized by metal–dielectric stacks supporting coupled surface plasmon polaritons (SPPs). Quantum emitters placed inside or on top of these structures have been shown to experience radiative decay rate enhancement, with the former having greater effect due to better coupling to high-k modes [5–9]. Patterning of HMMs has been shown to strongly enhance radiative decay rate for quantum emitters [8,10]; however, to the best of our knowledge, simultaneous enhancement of radiative decay and light extraction had not been shown to date. Following the proposal of a bullseye grating as an outcoupling mechanism [11], we show in this Letter, for the first time to our knowledge, experimental verification of simultaneous enhancement of SE and outcoupling of high-k modes generated by embedded dipole emitters, using a high contrast bullseye grating.
The structure [shown schematically in Fig. 1(a)] consists of seven periods (7P) of alternating layers of aluminum oxide (Al2O3) at ∼20 nm thickness and silver (Ag) at ∼12 nm, with ultrathin Germanium (Ge) (∼1–2 nm thick) seed in between. A spin-coated active layer of quantum dots (QDs) is embedded in the middle of the fifth Al2O3 layer (for full details of the fabrication see Sections 1 and 5 of Supplement 1). In the fabricated structure, a single period is defined as a unit cell of Al2O3/Ge/Ag layers. The fabrication is conducted in two stages. Stage 1 consists of four periods (4P) and an additional Al2O3 layer with embedded QDs. Stage 2 completes the full seven period (7P) structure. We determined the exact thickness of the dielectric and metallic layers from cross-sectional imaging with a transmission electron microscope (TEM) [Fig. 1(b)], and the permittivity constants of the thin layers of Ag/Ge and Al2O3 were determined from spectroscopic ellipsometry measurements. Knowing the layers' permittivity and the exact fill fraction of metal in the structure, we calculated the components of the effective anisotropic permittivity using effective medium theory [Fig. 1(c) and Section 2 of Supplement 1). Above a wavelength of ∼440 nm, the permittivity components parallel (∥) and perpendicular (⊥) to the interface have opposite signs, which lends a hyperboloid shape to the isofrequency contour (IFC) according to the dispersion relation equation
(1)kx2+ky2ε⊥+kz2ε∥=ω2c2.

(d) Lifetime distribution of QDs on glass, 1P, 4P, and inside a 7P nonpatterned HMM.
The hyperbolic shape of the IFC is schematically shown in the overlay of Fig. 1(c) along with the spherical IFC of air, depicting the issue of mode mismatch between free space and HMM. The spectrum of the QDs used in the experiment is also shown in Fig. 1(c) as a dashed line.
In a HMM, the origin of the high-k modes stems from the coupling between SPPs supported by individual metal–dielectric interfaces. The exact dispersion of the modes depends on the multilayer period (lattice pitch) and metal–dielectric layer thicknesses where the highest allowed propagating k vector is limited by the finite period of the multilayer. These coupled plasmonic modes create local enhancement in the photonic density of states (PDOS) and provide a radiative decay channel for quantum emitters [5,11].
To test the effect of high-k modes on spontaneous decay rate, a fluorescence lifetime imaging microscopy setup (see Section 5 of Supplement 1) was employed to obtain the lifetime distribution in an area size of 20 μm×20 μm of four samples. Figure 1(d) shows the lifetime distribution of 7P and 4P in comparison to a control sample consisting of a single period (1P), and a reference sample of QDs on a glass substrate. We observe that the measured lifetime becomes shorter as the number of periods is increased, indicating the presence of high-k modes. The measured reduction is comparable to previous reports [6,7], with the 7P structure showing decay rate enhancement β≡tRef/t7P=9.5 relative to glass, where tRef and t7P are the average lifetimes of the QDs on glass and in the 7P structure, respectively. These values are extracted by fitting the distribution with an asymmetric peak function. In addition to the measurement, the expected decay rate enhancement was analytically calculated, and shows a good match to the experimentally obtained values (see Section 3 of Supplement 1).
It is appropriate to note that, in plasmonic materials, a part of the lifetime shortening could be attributed to nonradiative metal quenching. The quenching effect for this type of HMM has been rigorously investigated in previous work [11], and the location of the emitters has been selected to minimize the effect of quenching.
To simulate the electric field inside the fabricated structure we used commercial finite-element-method (FEM) software COMSOL. Figure 2(a) maps the electric field generated by a dipole inside the 7P HMM, showing an X-shape radiation pattern known as resonance cone [11,12]. Hyperbolic dispersion also changes the direction of the Poynting vector, which is orthogonally oriented to the IFC and is thus contained within the resonance cone. Therefore, the energy flow due to high-k modes is inherently directed toward the surface of the HMM [11]. However, the electric field becomes evanescent at the air interface so that most of the dipole emission is internally reflected at the top and bottom interfaces, as can be seen in Fig. 2(a). To translate the evanescent field into propagating waves, an appropriate grating structure must be designed.

(b) Outcoupled power in an angle range of −45° to 45° as a function of grating period and height. (c) Top, outcoupling of the evanescent field by an optimized Ge grating with half period 125 nm and height of 60 nm. Bottom, nonpatterned HMM shown on the same scale. (d) Far-field emission of dipole ensemble (arb. units) for optimized grating and nonpatterned HMM.
Due to the difficulty in extending the Green's function approach to arbitrary geometries and random dipole orientations, a numerical approach was used for the grating design. Multiparameter FEM simulations for grating height and periodicity for several fabrication-compatible materials were optimized to maximize outcoupling [Fig. 2(b)]. Despite being lossy in the visible range, Ge was selected for the grating implementation over other compatible dielectrics due to its high index of refraction, which allows it to function as a high-contrast grating (HCG) with air [13], thus aiding the outcoupling of high-k modes (see Section 4 of Supplement 1). The spectral bandwidth of the optimized grating is ∼50 nm, which fully covers the emission spectrum of the QDs (see Section 4 of Supplement 1).
In the top panel of Fig. 2(c), we show the near field emission pattern from a 7P HMM with an optimally designed bullseye grating (Δ=125 nm, h=60 nm). For comparison, the bottom panel shows the emission pattern without a grating outcoupler. In Fig. 2(d), the far-field emission pattern is plotted for a dipole ensemble in an HMM with and without the grating. The ensemble approach is used for calculations and simulations throughout this Letter to account for the random dipole orientations of the QDs and their PL spectrum (see Section 3 of Supplement 1).
To experimentally demonstrate the effect of grating period on outcoupling efficiency, bullseye gratings with half-periods Δ=125, 150, 170, 200, 250, 265, and 300 nm were patterned onto a polymethyl methacrylate (PMMA) resist layer that was spin-coated on top of the HMM. The gratings written on the PMMA were used as a mask for depositing Ge and realizing the high-contrast bullseye gratings (see Section 5 of Supplement 1). Scanning electron microscope (SEM) images of the Δ=150 nm grating and an array of gratings with different periodicities are shown in Fig. 3.

The photoluminescence (PL) and lifetime of the patterned HMM were measured simultaneously using the confocal microscope setup described in Section 5 of Supplement 1. Figure 4(a) shows a PL image of the grating array. Enhanced light emission is clearly seen in the gratings while the dark background elucidates the evanescent nature of the high-k modes, which cannot propagate to the far field without an outcoupling mechanism. The bright spots in the emission seen inside the gratings are due to the presence of clusters of QDs formed during spin-coating, and were not included in the image analysis.

Details of the measurement technique can be found in Section 5 of Supplement 1. (b) Experimentally measured ratio between the intensity at the center of the grating to that of nonpatterned background for 7P and 1P for different grating periods. Solid lines are the calculated ratios from simulations. Inset, fluorescence lifetime map of Δ=125 nm.
The ratio of the average PL intensity from the gratings to the nonpatterned areas is presented in Fig. 4(b), together with the results of numerical calculation of this ratio from FEM simulations. In both simulation and experiment, the amount of outcoupled light increases for smaller grating periods, with Δ=125 nm yielding an intensity contrast of 20∶1 in comparison to the nonpatterned regions. This sharp contrast could only be attributed to outcoupling of multiple high-k modes since no other power flow mechanism exists in the structure. In comparison to the HMM, the 1P control sample shows far smaller contrast between the background and the gratings due to the lack of high-k modes. An additional feature observed in the emission pattern from the HCG is the presence of the dark center. Our simulation of the electric field in the near and far field also show the same dark spot, which is most clearly observed for Δ=125 nm (see Section 6 of Supplement 1).
In addition to PL intensity, we studied the time dynamics of PL emission of QDs located inside and outside the grating regions. Conventional wisdom dictates that the bullseye gratings will degrade the Purcell enhancement of the QDs, resulting in longer lifetimes as is the case in resonant cavity approaches [1,2]. Counterintuitively, we observe a reduction in lifetime for QDs located under the bullseye (≈1.9 ns) relative to those located away from the bullseye (≈2.6 ns). The inset in Fig. 4(b) shows a fluorescence lifetime map for Δ=125 nm, where the two regions are clearly observed (lifetime kinetics curves are shown in Section 7 of Supplement 1). We elucidate the physics of this observation below.
Simulations indicate that the Purcell enhancement is nearly equal for a dipole ensemble located below or away from the bullseye. The reason for the relative insensitivity to the outcoupling mechanism is that, in an HMM, the Purcell enhancement for embedded emitters is largely driven by the massive local electric field enhancement that the high-k modes provide at the location of the dipoles. The dielectric grating does scatter these bulk modes into free space; however, it only provides a relatively weak perturbation of the field enhancement and the local PDOS remains largely unperturbed. However, a reduction in lifetime was observed experimentally in the grating region as mentioned above. To understand this observation, one needs to take into account the proportion of outcoupled light emanating from the two-dipole orientations. At locations far from the grating, we only collect the small portion of light emitted by the randomly oriented dipoles, which is uncoupled to high-k modes and can reach the far field without an outcoupling mechanism. In contrast, at the location of the grating, we predominately collect scattered high-k emissions from vertically oriented dipole moments [see Fig. 2(d) and Fig. S4 in Supplement 1], which have better coupling to the HMM modes than horizontal dipoles and therefore also experience a larger Purcell enhancement (Section 3 of Supplement 1). Since the vertical dipole moment experiences a larger Purcell enhancement (see Fig. S2 in Supplement 1), the average lifetime within the grating is shorter (see Section 7 of Supplement 1).
Even with optimized grating design, the total number of outcoupled photons is eventually restricted by material loss in metal–dielectric structures such as the one shown here. In this context, the recent work on low-loss HMMs with extremely high PDOS [14] provides an ideal platform to implement such outcoupling mechanisms for embedded emitters. HCGs can be realized with a variety of CMOS-compliant materials. This advantage promises increased efficiency in the near infrared, where the loss in materials such as Ge and Si is lower.
In summary, we present an active HMM with a high-index-contrast grating that provides both enhancement in the SE rate and efficient light extraction of high-k modes into the far field. We show reduction in the SE lifetime by a factor of ∼10 along with a factor of ∼20 enhancement in light extraction from QD emitters embedded inside the HMM. Control of SE and extraction of light from active HMMs is an important step in achieving practical photonic devices such as subwavelength lasers, superluminescent LEDs, and single–photon sources.

A concerted effort to increase colorectal cancer screening rates led to a dramatic increase in NYC screening colonoscopy rates among average-risk men and women and eliminated racial/ethnic disparities in screening. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the program may serve as a foundation for other communities to boost cancer screening rates.
Colonoscopies are one of the most effective ways to reduce colorectal cancer incidence and mortality, and there is now a national campaign to reach colorectal cancer screening rates of 80 percent by 2018. While rates are increasing, there continue to be significant differences between states and within states. A report spearheaded by Steven Itzkowitz, MD, and Lina Jandorf, of the Icahn School of Medicine at Mount Sinai, now provides a framework for how communities might learn from a program initiated by the New York City Department of Health and Mental Hygiene to increase screening rates and ensure equal access based on race/ethnicity.
In 2003, an Advisory Committee organized a citywide coalition, called the C5 Coalition (NYC Citywide Colon Cancer Control Coalition) that included physicians, hospitals, ambulatory surgery centers, health care plans, unions, medical societies, and advocacy and survivor groups. Initiatives to increase screening colonoscopy rates, while at the same time targeting communities with the lowest rates, included public education, outreach to health care providers, culturally and linguistically tailored campaigns, and other programs to boost awareness and overcome hurdles to effective screening.
As a result of this concerted effort, the overall screening colonoscopy rate in New York City rose from 42 percent in 2003 to 62 percent in 2007, a rate that was not reached nationally until 2012. Moreover, this was accompanied by a sustained elimination of disparities based on race/ethnicity. "The increased screening rate from 2003 to 2012 translates to 833,000 New Yorkers who have undergone screening colonoscopy and represents an important public health intervention," said Dr. Itzkowitz. In 2014, the screening rate reached nearly 70 percent.

The only major connection between the new film version of Flatliners and the 1990 original is Kiefer Sutherland, who was one of the two leads of the first film along with Julia Roberts. But so far, Sutherland and his character have been absent from the film's marketing, which has focused instead on Ellen Page and the new group of ambitious medical students who believe they can make a major scientific breakthrough by killing themselves and then bringing each other back to life. What could possibly go wrong with that plan?
Flatliners opens in theaters on September 29. Presumably with more than just this one single shot of Kiefer Sutherland in it (although it would be kind of amazing if he literally appeared in one shot and no one ever discussed it or noticed him).

Discussion in 'Auto News' started by kikie, Aug 23, 2018.
Kalashnikov is developing an electric car based on the Izj Kombi from the '70.
Kalashnikov says that this electric supercar is going to be a direct comptetion for Tesla and other electric cars. There is no information available yet, only that they are working on this CV-1 concept car.
I love random companies making cars, or at least concepts.
Snikle, SecretAgentZero and Turbo like this.
Seems more like competition for "other" electrics than for Tesla.
Supercar in what decade, 1970's?
Kalashnikov claims the vehicle generates 295 horsepower, drawing juice from a 90 kWh battery pack. Featuring a "revolutionary" inverter capable of handling gobs of current and an advanced (or at least contemporary) powertrain monitoring system, both developed in-house, the vehicle offers a driving range of 217 miles. Memories of the Warsaw Pact come standard. Unlike the original hatchback, this vehicle rockets to 62 miles per hour in 6 seconds.
It's slow when compared to the Tesla, even the base Model 3 is faster and has better range on a 75kWh battery.
Kalasjnikov should stick to making firearms.
Wasn't the Anglo-version of the Калашников name supposed to be just Kalashnikov? With the j it would have been either translated into Spanish or originated from Poland or some similar place. Likewise for the "Izj"
How much of this "Kalishnikov claims they have made Tesla killer" nonsense spreading around automotive blogs today is actually something that came from the company and not re-contextualizing it as "lol Russia" or trying to distract everyone from Musk's ranting tweets about Model 3 bumpers falling off when faced with light breezes?
I feel, they were more inspired by shade tree engineers, converting their own Austin Minis and Beetles to electric.
So you know about it too.
First, this particular model is not a "Tesla killer" of any kind. Someone said this nonsense and journalists are repeating this (with giggles, I guess).
The maker says it's only a test platform. They took an old and cheap car, Izh Kombi (which costs around $500 in decent condition), and equipped it with electric engine/batteries. If they keep the development up, they'll use a proper, modern base and, perhaps, launch it into serial production.
Second. The base car is, as it's said already, Izh 2125, also known as Kombi. Produced from 1973 to 1997. The original version looked better than this.
The 1982 restyling (I suppose Kalashnikov used this version as a base) gave it an ugly look. However... there's something attractive in this ugliness, too.
Another likely reason why they used the Izh is because it was produced in Izhevsk - the same city where Kalashnikov makes its firearms.
Their PR managers don't know what is "supercar", that's all.
295 hp is still not bad, though.
Any self respecting Moskvich should be either brick red, sky blue or grass green. What are these capitalist nonsense colors?
Anyway, its obviously a mule targeting to get attention and its successfull on that.
The 1970s appearance looks interesting I guess, though I'm not sure that this will be capable of doing any Tesla killing.
Indeed, for some reason these old Russian cars appealing.
Maybe this CV-1 will be very ugly but gorgeous at the same time.
Reminds me of Star Wars.
Indeed, it is part Robocop.
It's been memed by the Russian internet already.
Turbo, 05XR8, Snikle and 1 other person like this.

5 Things Job Candidates Obsess Over That Hiring Managers Don't Care About
Not all job-search details are make-or-break, so stop wasting your energy on how fancy your resume is.
[Photo: Flickr user Pedro Ribeiro Simões]
By Maureen Dempsey 6 minute Read
It doesn't matter how much work experience you have, or how many interviews you've knocked out of the park–job hunting is bound to make even the most confident candidates feel insecure.
And since so many factors are out of your control–like whether you'll hear back about that perfect fit opportunity–it's no wonder many people find themselves attempting to regain a little power by obsessing over what they can control.
But the truth is, not all job-search details are make-or-break.
To help you discern what's worth your worry–and what's definitely not–we chatted with two career experts to identify five easy-to-obsess-over details that hiring managers really don't care about … and what to focus on instead.
1. How Fancy Your Resume Looks
In today's competitive job market, it's crucial to make your CV shine brighter than the hundreds of others on a hiring manager's desk. Often, that pressure leads people to toil over the glossiest resume template–with fancy fonts, bold pops of color, and custom sub-sections–in an effort to express their exceptional flair for style.
But unless you're applying for a design position and need to showcase those skills, Alison Green, a former nonprofit chief of staff and author of the AskaManager blog, is giving you permission to quit obsessing.
"No employer is going to hire you just because you have a beautifully laid-out resume," she says. "Plus, it makes it look like you don't have a clear idea of what things really matter."
What Does Matter: "Standing out is about the strength of your candidacy, which is something you can't buy, fake, or promote through even the most beautiful font choice," Green says.
If you really want to prove you're a strong candidate, create an easily readable document that prominently highlights your professional accomplishments.
For example, maybe you exceeded your sales targets for three years in a row, successfully serviced your company's most difficult account, or were chosen to represent your department at a major industry conference–make sure these points stand out on your CV.
One other thing to keep in mind? Stick to the facts, Green says, adding that hiring managers won't give much weight to overly subjective descriptions and self-assessments you can't substantiate, like "excellent management skills" or "creative communicator."

2. If You Send a Handwritten Thank You Note
Back in the day, a thoughtfully composed, handwritten note was considered to be the best way to properly complete the interview process. But fast-forward to today's hyper-connected world, when even hiring seems to move much faster–causing many job seekers to stress about the appropriate way to reach out post-interview.
Stacey Hawley, a career and leadership development coach and founder of The Credo Company, insists that stressing over how you follow up isn't what hiring managers are concerned about.
"Interviewers just care that they get [a note]," she says, adding that it's best to send it–using the medium of your choice–within 48 hours of your meeting.
What Does Matter: Rather than simply thanking hiring managers for their time–something that doesn't add value to the decision-making process–Hawley says to make sure your note contains meaningful information that proves you were paying attention and are still interested in the position.
"Think about the conversation, and write something both personal and business-related," she suggests. "Tell them how much you appreciated discussing a certain business topic, then thank them for sharing their insights about something personal."

Hiring managers often skim a resume first, so jam-packing yours with every job you've ever had reduces the chance that their eye will land on what you truly want them to see.
3. Whether Your Resume Fits on One Page
You've probably heard traditional career advice that warns job seekers against submitting a resume that spills over to two or more pages.
After all, a 2012 study found hiring managers spend just six seconds reviewing a candidate's materials before determining whether the person is a good fit.
So those hours you spent editing, adjusting margins and tweaking the font size to squeeze every last bit of information on a single page seems reasonable enough.
But Green says you can throw this advice out the window–if you've been out of college for at least five years and have enough legitimate experience to include.
What Does Matter: Now that you have carte blanche to make your resume as long–or short–as you see fit, concentrate on making sure you've highlighted only the most pertinent facts from your job history.
"Hiring managers often skim a resume first, so jam-packing yours with every job you've ever had reduces the chance that their eye will land on what you truly want them to see," Green says.
So give the majority of your resume's real estate to the most recent and relevant information–and downplay the rest. "You could even put the internships or junior positions together without bullet points," Green adds. "You don't need to treat them with equal weight [compared to full-time staff positions]."
Another option? Organize your resume by "Relevant Experience" and "Other Work Experience," rather than chronological order. "This allows you to highlight the experiences and skills that the hiring manager or recruiter is most interested in, while still addressing your overall work history," Green says.

4. Crafting a Clever Cover Letter
If writer's block always seems to hit just as you sit down to write the perfect cover letter, you certainly wouldn't be alone.
But the truth is that a cover letter doesn't have to be that complicated. "Just imagine you're writing an email to a friend about why you'd be perfect for this job," Green says. "That's the tone you want."
What Does Matter: The key to a great cover letter is to emphasize the passions and personal traits that make you uniquely qualified to excel in a particular job—but don't come across in your resume.
"Somewhere along the line, people got the idea that a cover letter should offer the same details as your resume, but it's the opposite," Green says. "If all you do is summarize your work history, you're squandering an opportunity."
She offers an example of a woman who applied for an administrative position, but didn't have as much experience as other candidates Green was considering.
"In her cover letter, the woman explained how her friends teased her for neurotically color-coding her closet and alphabetizing her spices, and she talked about how she's known in her peer group for her love of organization," Green says. "You cannot put that in a resume. But it told me so much about the type of person she was, and likely the type of approach she would have to that job."
The result? The woman scored an interview–and the job.
For job seekers, this is a major event in their lives, but for the interviewers, they're meeting other people and, of course, working! Work gets in the way of the interview process all the time.
5. Why You Haven't Heard Back
Whether you've just submitted your resume and are wondering if you'll be called for an interview, or you're waiting to hear if you'll be asked back for a second one, it's hard to be patient … or think of anything else.
Hawley sympathizes–but warns job seekers not to check in too often.
"For them, this is a major event in their lives, but for the interviewers, they're meeting other people and, of course, working! Work gets in the way of the interview process all of the time," she says. "I know it's hard, but be patient. The last thing you should do is email the interviewers and ask when you'll hear back–repeatedly."
What Does Matter: If you do snag an interview, satisfy your curiosity by asking for a timeline before you leave. "If you know when the powers-that-be want to make a decision by, it's reasonable to check in after that point for an update," Green says.
After that, shift your focus back to what you can control: continuing your job search.
"For your mental health, the best thing you can do is pretend you didn't get the job as soon as you walk out the door," Green says. "Put it out of your mind. Then you won't agonize day after day."
Bonus: You'll be pleasantly surprised when you do get that phone call with an offer.

Creamy Potato Soup with a Twist | Jenny. Maker.
Now that the cold weather has arrived and the holiday madness is in full swing, easy, hearty meals become our go-to recipes. DH2b requested creamy potato soup last month, which I had never tried, and we've since had it three times. It's warm, comforting and filling - all the best traits of a winter dish. As usual, I've tailored this recipe for his "no veggie" rule but the powders could easily be changed to the fresh deal. Last night, I made one final tweak that received extensive enthusiasm so, I wanted to share my twist.
Melt the butter in a large pot. Add andouille, brown. Sprinkle in flour, onion, garlic, and parsley; cook, stirring for 2 minutes. Add broth slowly, stirring in each addition.
Add milk, cream, potatoes, Worcestershire sauce, mustard, allspice, thyme, salt, wine, and cayenne. Allow to simmer and thicken, stirring frequently, until the potatoes are cooked through, approximately 25 minutes. If thicker soup is desired, smash potatoes with the back of a spoon. If a thinner soup is preferred, slowly add milk until desired consistancy is reached. Serve warm.
The addition of the andouille makes this meal higher in protein, a bit more filling, and gives it a little kick. You could add more or less (we had two on hand when I thought to add them) or none at all. The soup is excellent either way!
Hopefully, this ticks one easy meal off your list this holiday season! Have you any to share?

Studies show that on average an e-mail is associated with 130 accounts that require a password and it is humanly impossible to remember so many of them. Key findings indicate that password reuse across different applications is frequent, and that most users rarely change passwords. Studies have found that more than 80% of people reuse passwords.
Cyberattacks and data breaches are becoming a fact of life for government agencies, businesses and individuals alike in today's digitized and networked world. The point to be noted is that 81% of data breaches leverage a stolen or weak password.
While there are legitimate purposes to the Dark Web, it is estimated that over 50% of all sites on the Dark Web are used for criminal activities, including the disclosure and sale of digital credentials.

Digital credentials such as usernames and passwords connect you and your employees to critical business applications, as well as online services. Unfortunately, criminals know this — and that's why digital credentials are among the most valuable assets found on the Dark Web. To keep your digital assets protected you need visibility and the threat intelligence to stay ahead of the cyber criminals.

engineering and/or phishing attacks. Often, the identification of fake email accounts indicates that an organization has been targeted by individuals or groups in the past.
Employees often recycle passwords throughout their work and personal networks. If your internal requirement is to have a capital letter and special character, it's common practice for employees to use a password they are familiar with, and add a capital letter and exclamation mark. (Example: Exposed Password: cowboys, Variation: Cowboys!, Cowboys1, Cowboys!1, and so on.)
