We estimated this added heat wave effect for each heat wave using community-specific generalized linear models. We controlled for daily maximum temperature to separate effects of heat waves from effects of single days of hot temperature; we also controlled for day of the week and adjusted dew point temperature and time trends to account for seasonal and long-term changes in mortality patterns in a community. We used a nonordered categorical factor to identify heat waves. This variable took a different value for each heat wave. This approach is similar to methods used in earlier studies to compare mortality risk on heat wave days with non-heat wave days (Anderson and Bell 2009 (link); Hajat et al. 2006 (link)); however, our model extends the earlier method by allowing risk of mortality to differ by heat wave. Because we estimate a separate effect for each heat wave, we can investigate effect modification by heat wave characteristics (e.g., duration). The model can be stated as
where μtc = expected mortality rate for community c on day t; δ0 = model intercept; ac = vector of regression coefficients for heat waves for community c (one per heat wave); HWt= 0 if day t is a non-heat wave day, 1 if day t is the first day of any heat wave, 2 if day t is the second or later day in the first heat wave in the community, 3 if day t is the second or later day in the second heat wave in the community, and so forth; yc = vector of regression coefficients for day of the week for community c; DOWt = categorical variable for day of the week; ns(timet) = natural cubic spline of time, with 3 degrees of freedom (df) per warm season (1 May–30 September); ns(Ttc) = natural cubic spline of maximum temperature for community c for day t (df = 3 with knots at quantiles); and (Dtc) = natural cubic spline of adjusted dew point temperature for community c on day t (df = 2).
where β̂h = estimated effect of heat wave h on mortality, βh = true effect of heat wave h on mortality, v̂h = statistical variance of β̂h, μ = true average heat wave effect across all heat waves, τ2 = between-heat wave variance of the true effect, and n = number of heat waves.
This model was fit separately for each community. This method is often used to combine effect estimates across communities in air pollution and temperature studies (Anderson and Bell 2009 (link); Bell and Dominici 2008 (link)). National and regional heat wave effects were estimated using similar multistage hierarchical Bayesian models. Results were generated separately for three U.S. regions, Northeast, Midwest, and South, based on regions used previously (Anderson and Bell 2009 (link); Barnett 2007 (link)). Insufficient numbers of communities precluded estimates for other regions.
To assess the long-term repeatability of the dietary questions on the touchscreen questionnaire, as well as the new partial fibre score, we used the subsample of participants who had completed the repeat assessment centre visit and examined the agreement between participants’ responses to the dietary questions on the touchscreen questionnaire completed at baseline and the repeat visit. For this analysis, questions where the possible responses were categorical, i.e. questions on fish, meat, cheese, types of milk, spread, bread, cereal, salt added to food, temperature of hot drinks, major changes to diet, and variation in diet, we cross-tabulated the answers as recorded. For questions that used direct entry responses, we truncated or collapsed answers into categories to enable cross-tabulation as follows: for servings of fruit and vegetables we used 0, 1, 2, 3, 4, ≥5; for the derived partial fibre score we categorised participants into fifths based on the whole cohort. For age last ate meat we used 0–10, 11–20, 21–30, 31–40, 41–50, 51–60, ≥61 years; for slices of bread we used 1–5, 6–10, 11–15, 10–20, 21–25, 26–30, ≥31; for bowls of breakfast cereal we used 0, 1, 2, 3, 4, 5, 6, 7, ≥8, for cups of tea and coffee and glasses of water we used 0, 1, 2, 3, 4, 5, ≥6. For all questions, participants selecting ‘do not know’, ‘prefer not to answer’ or ‘less than one’ were assigned to separate categories, except for number of bread slices where ‘less than one’ was combined with ‘0’ because of very low numbers for both of these groups. For the question on foods avoided we created binary variables for each food item, e.g. consumers/non-consumers of dairy products.
After excluding participants who answered ‘do not know’ or ‘prefer not to answer’ at either baseline or the repeat visit, we also assessed agreement using the κ coefficient. Bootstrapping with 10 000 replications was used to calculate CI around the κ coefficient. In a separate analysis, we also further excluded participants who reported, at the repeat visit, making a major change to their diet in the past 5 years. We also examined κ coefficients by sex, age (<55 years, ≥55 years) and BMI (<25 kg/m2, ≥25 kg/m2). For most of the dietary touchscreen questions, the categories of responses to the dietary questions were ordinal, ranging from least frequently eaten to most frequently eaten; therefore for these questions the κ coefficient with quadratic weighting was used, which is equivalent to the intra-class correlation coefficient and allows for the fact that a change from category 1 to category 2 reflects closer agreement over time than, for example, a change from category 1 to category 4(9 ). κ Values >0·80 indicate excellent agreement, values between 0·61–0·80 substantial agreement, 0·41–0·60 moderate agreement, 0·21–0·40 fair agreement, and ≤0·20 poor agreement(10 ). For questions where the responses were not ordinal, e.g. bread or spread type mainly used, only the percentage in the same category is given, κ values were not calculated.

The hitting of this temperature gave birth to the flame inside the beaker, which instantly burnt all the gel and converted it into ash. As a result of this combustion, the temperature inside the beaker promptly increased which lead to the following reaction for parent composition to occur:
The molecular oxygen (O2) and nitrogen dioxide (NO2) were evolved as a byproduct in this reaction. For subsequent samples, the stoichiometric amount of La(NO3)3·6H2O was substituted at Nd(NO3)3·6H2O site. After that, the ash was put into an Agate mortar and pestle for grinding and converted into fine powder. The synthesized powder was then placed into ceramic cups and calcined at 800 °C for 3 h in a Nabertherm furnace to develop a pure phase.24 (link) This calcined powder was pressed using an Apex hydraulic press to make cylindrical pellets of 7 mm diameter and ∼1 mm thickness by applying a force of 30 kN. All the pellets were then sintered at 350 °C for 1 h to make them hard.25 (link) The pictorial representation of this whole synthesis process is shown in
An advanced Bruker D8 X-ray diffractometer (XRD) was used to analyze the crystalline phase of the synthesized series. A Nova NanoSEM-450 field emission scanning electron microscope (FESEM) was utilized to investigate the morphology and elemental composition. A Radiant's Technologies Inc., USA precision multiferroic tester was used to probe ferroelectric properties. Magnetic properties of synthesized series have been carried out by Cryogenic vibrating samples magnetometer (VSM).

Mostafa Maged four-stitch technique for closure of the episiotomy.
Identification of the apex of the episiotomy, then a simple suture is taken (0.5 cm) behind the apex of the episiotomy. First, the needle is inserted at the vaginal mucosa (epithelium) of the right edge of the episiotomy then extracts the needle.
The second stitch is inserted on the muscle layer of the same side (right side) of the episiotomy cutting edge then extracting the needle.
Then, insert the needle again on the left side of the episiotomy incision in the muscle layer on the left side of the episiotomy incision directing the tip of the needle upwards parallel to the second stitch taken.
The fourth step is inserting the needle in the vaginal mucosa (epithelium) of the left side parallel to the first stitch. Continue suturing the episiotomy incision continuously in the same way till reaching the remnant of the hymen (fourchette). Then, I make a loop knot at the fourchette. Then, suturing the superficial perineal muscle in a continuous manner and the skin in a subcuticular manner as well. Mostafa Maged technique is illustrated in a model of uterus in
Procedure (Patients with routine traditional closure of the episiotomy): patients of controlled group with routine closure of episiotomy
Perineal trauma is traditionally repaired in three stages: a continuous locking stitch is inserted to close the vaginal trauma, commencing at the apex of the wound and finishing at the level of the fourchette with a loop knot. The perineal muscles are then re-approximated with three or four interrupted sutures and finally, the perineal skin is closed by inserting continuous subcutaneous or interrupted transcutaneous stitches.
The skin is then closed with inverted interrupted stitches placed in the subcutaneous tissue a few millimeters under the perineal skin edges (not trans-cutaneously).

Gilgit Baltistan has around 154 mm of rain each year. Water irrigation for land cultivation is supplied by rivers and streams overflowing with snowmelt and glacial water from mountainous regions. Summer is more prolonged, drier, and hotter. Strong sunlight occasionally elevates temperatures beyond 40 °C (104 °F), although the winter's average temperature remains below 10 °C. There are numerous landslides and avalanches in the region due to the harsh weather conditions44 (link). The region's geological traits and soils, which also play a crucial role, are fragile.
