A field experiment was conducted at BINA substations, Rangpur and Magura in 2018-19 to evaluate the different row spacing on the yield and yield contributing characteristics of advance mustard lines RM-03, RM-07, RM-10 along with one check variety BARI sarisha-15 during Rabi season. BARI sarisha-15 was irradiated with 700 Gy Cobalt 60 (60Co) Gamma source and advanced mutant lines M6 generation of mustard mutant (RM-03, RM-07, RM-10) were evaluated along with the check variety BARI sarisha-15 using four different row spacings viz. 20cm, 25cm, 30cm and 35cm. The experiment was laid out in split-split plot design with three replications. Among the advance lines, RM-03 produced the highest seed yield (1.60 t ha-1) followed by RM-10 (1.50 t ha-1). Among different line spacing, 20cm showed highest seed yield (1.66 t ha-1). The interaction of mutant/variety and location revealed that the yield of RM-10 was the highest (1.54 t ha-1) at Rangpur. The interaction effect of line spacing and location showed that 25cm line spacing produced the maximum seed yield (1.68 t ha-1) in Magura followed by 20 cm (1.64 t ha-1) in Rangpur. The interaction effect of mutant and line spacing showed that mutant line RM-03 at 20 cm produced maximum seed yield (1.68 t ha-1) in Rangpur. The interaction effect of mutant/variety, line spacing and location showed that RM-10 produced the highest seed yield (1.73 t ha-1) at 20cm line spacing in Rangpur followed by RM-07 (1.66 t ha-1) at same spacing.

Lack of winter chilling (480 hrs. at or below 7.2°C by 02/28/89) occurred along Alabama's Gulf Coast in the winter of 1988-89. Varieties requiring 650 hours of chilling or more were under stress. To evaluate hydrogen cyanamide (HC), a product used world wide to replace part of some fruit plants chilling req., a study was conducted along the Gulf Coast using Bicentennial (700 hr.), Sentinel (850 hr.) and Loring (900 hr.) peach varieties. Full tree sprays (applied to drip with handgun) using 0, .5 and 1% a.i. plus .25% × 77 were applied 03/01/89. Fruit buds were dormant to slight swell when sprayed. HC greatly enhanced rate and % of leaf bud break at the 1% conc., for all varieties. Rate and % of flowering were significantly increased at 1% conc. in Loring and Sentinel but nearly all fruit dropped. Flowering, yield and fruit size of Bicentennial-were significantly improved at .5 and 1% conc. HC was effective in replacing lack of chilling in this variety.

The two-step conversion of industrial liquefied hydrocarbon gases (LHG) on NIAP-07-01 (NKM-1) and NIAP-03-01 catalysts for the production of hydrogen-containing gases was investigated. The experiments were carried out in flow reactors with a fixed catalyst bed at a pressure of 0.1 MPa under the following conditions: temperature 350–450 °C, gas hourly space velocity (GHSV) 1000–3000 h–1, steam-gas ratio 4 : 1–8 : 1 (pre-reforming); and temperature 700 °C, GHSV 2000 h–1, air-gas ratio 1.2 : 1 (steam-air reforming). Under the studied conditions, the concentrations of components of the converted gas correspond to the equilibrium values calculated within the Peng-Robinson model. The conversion of methane homologs in the pre-reforming step was found to be virtually 100 %; therewith, the methane concentration reached 32–54 %, and that of hydrogen, 24–47 %. To prevent the formation of elemental carbon (carbonization), pre-reforming of hydrocarbon gases with a high methane equivalent should be performed at H2O : C > 2. In the two-step reforming, the yield of hydrogen-containing gas reaches 15.6 m3 from 1 m3 of the initial LHG with the hydrogen content 41.81 %, and the total content of CO and H2 exceeds 52 %.

SUMMARYClimate change experts predict the number of nuisance-biting arthropods in England will increase but there is currently no known surveillance system in place to monitor or assess the public health impact of arthropod bites. This retrospective ecological study utilized arthropod bites requiring healthcare from five national real-time syndromic surveillance systems monitoring general practitioner (GP) consultations (in-hours and out-of-hours), emergency department (ED) attendances and telephone calls to remote advice services to determine baseline incidence in England between 2000 and 2013 and to assess the association between arthropod bites and temperature. During summer months (weeks 20–40) we estimated that arthropod bites contribute a weekly median of ~4000 GP consultations, 750 calls to remote advice services, 700 ED and 1300 GP out-of-hours attendances. In all systems, incidence was highest during summer months compared to the rest of the year. Arthropod bites were positively associated with temperature with incidence rate ratios (IRRs) that ranged between systems from 1·03 [95% confidence interval (CI) 1·01–1·06] to 1·14 (95% CI 1·11–1·16). Using syndromic surveillance systems we have established and described baseline incidence of arthropod bites and this can now be monitored routinely in real time to assess the impact of extreme weather events and climate change.

8614 Background: FN is a frequent life-threatening consequence of cytotoxic chemotherapy (CT). G-CSF reduces the risk of FN, but primary (1ry) prophylaxis using G-CSF may be cost efficient only if FN incidence is ≥20%. The identification of pts at high risk for FN with simple criterias would be useful in clinical practice. Here we report a randomized phase II trial comparing G-CSF in 1ry vs 2ry prophylaxis in a high risk group of pts (based on our risk model JCO 1996;14:737, Br J Cancer 2003;88:181). Methods: Pts ≥18 years with solid tumors or NHL at high risk for FN after CT were incluable: these were pts with day 1 or day 5 lymphocytes (Ly) count ≤700/μL AND “high risk CT” (HRCT) In pts with d1 and d5 Ly ≤700/μL, the observed incidence of FN was 40% and 66% respectively G-CSF (300 to 480μg/d from d6–12) was randomized either as in 1ry prophylaxis (Arm 1), or as 2ry prophylaxis after FN (Arm 2). Primary endpoint was the rate of grade 4 FN. Hypothesis was a reduction of 40% of the risk of FN with 1ry prophylaxis. Results: Between 03/97 and 12/04, 137 pts were included in 7 centers. The median age was 53 years (range 18–80) with 54% males. Most frequent tumors were sarcomas (36%), breast carcinomas (18%), lymphomas (15%), head and neck carcinomas (10%), and lung carcinomas (6%). 23% patients had PS>1 at the first line of chemotherapy. No difference was observed in terms of duration of hospitalization or antibiotherapy. Median number of days of G-CSF administration was 14 days (0–24) vs 0 (0–17) days (p<0.0000). After the 1st course, grade 4 FN was 38% in Arm 2 (2ry prophylaxis) and 25% in Arm 1 (1ry prophylaxis), showing a 34% reduction of FN in arm 1 (p=0.14): 1ry prophylaxis was associated with a significant reduction of FN using logistic regression (p=0.04). Incidence of FN after the 2 course in pts receiving 2ry prophylaxis was 22%. Among the subgroup of pts with PS>2 and Ly ≤700/μL, (a group with a reported 20% risk for early death, Br J Cancer 2001;85:816), 2 of 8 patients (25%) died after the 1st course, vs 0/13 in the G-CSF group (p=0.05). This difference was not significant in the whole group. Conclusions: This study confirms that lymphopenic pts receiving HRCT are a high risk group of pts for FN for whom 1ry prophylaxis with G-CSF reduces the incidence of FN. [Table: see text]

<p>Indonesia is a country that is a often hit by disasters, this is due to the meeting of 4 tectonic plates of the earth. The city of Padang is right at the meeting between the Indo-Australian plate and Eurasia so that it puts the city of Padang as one of the cities prone to earthquakes. This research analyzes the type C hospital building that was originally designed in the Medan city location to be designed in Padang city with the aim to determine the strength of the structure and the need for the width of the column reinforcement in the building. The first step is to determine the spectral response value of the Padang region earthquake, a short period of 0.2 seconds Ss = 1,289 g and a period of 1 second S1 = 0.549 g. Second is calculating dead load, live load and static earthquake load equivalent to SNI 03-1726-2012 and force output in using ETABS software, and third is calculating the column reinforcement area requirements. The results of the analysis show that the width of the column reinforcement there is a difference = 4750.00 mm against field data = 6801.24 mm in the dimensions of the column 500 mm x 500 mm with a value of = 2051.24 mm and an increase in the value of the calculation reinforcement area in the 700 mm column x 700 mm is = 9800.00 mm from the field data = 9068.32 mm with a selection = 731.68 mm.</p>

ImportanceMoyamoya disease (MMD) is a rare chronic cerebrovascular disease, and the outcomes of bypass management in adult patients remain controversial.ObjectiveTo categorize adult MMD based on asymptomatic, ischemic, and hemorrhagic onset and compare the outcomes (death, hemorrhagic stroke [HS], and ischemic stroke [IS]) of bypass surgery (direct or indirect) with those of conservative management.Design, Setting, and ParticipantsThis retrospective, nationwide, population-based longitudinal cohort study used Korean National Health Insurance Research data to identify adults (aged ≥15 years) with MMD who were diagnosed between January 1, 2008, and December 31, 2020, and followed up until December 31, 2021 (median follow-up, 5.74 [IQR, 2.95-9.42] years). A total of 19 700 participants (3194 with hemorrhagic, 517 with ischemic, and 15 989 with asymptomatic MMD) were included. Data were analyzed from January 2 to April 1, 2023.ExposuresBypass surgery and conservative management.Main Outcomes and MeasuresDeath constituted the primary outcome; secondary outcomes consisted of HS or IS. Kaplan-Meier survival curve and Cox proportional hazards regression analysis were applied. The propensity score–matching and stratified analyses were performed to control covariate effects.ResultsA total of 19 700 patients (mean [SD] age, 45.43 [14.98] years; 12 766 [64.8%] female) were included. Compared with conservative management, bypass was associated with a reduced risk of death (adjusted hazard ratio [AHR], 0.50 [95% CI, 0.41-0.61]; P &amp;lt; .001) and HS (AHR, 0.36 [0.30-0.40]; P &amp;lt; .001) in hemorrhagic MMD; reduced risk of IS (AHR, 0.55 [95% CI, 0.37-0.81]; P = .002) in ischemic MMD; and reduced risk of death (AHR, 0.74 [95% CI, 0.66-0.84]; P &amp;lt; .001) in asymptomatic MMD. However, bypass was associated with an increased risk of HS (AHR, 1.76 [95% CI, 1.56-2.00]; P &amp;lt; .001) in asymptomatic MMD. Both direct and indirect bypass demonstrated similar effects in hemorrhagic and asymptomatic MMD, except only direct bypass was associated with a reduced risk of IS (AHR, 0.52 [95% CI, 0.33- 0.83]; P = .01) in ischemic MMD. After stratification, bypass was associated with a reduced risk of death in patients younger than 55 years with ischemic (AHR, 0.34 [95% CI, 0.13- 0.88]; P = .03) and asymptomatic (AHR, 0.69 [95% CI, 0.60-0.79]; P &amp;lt; .001) MMD, but an increased risk of HS in patients 55 years or older with ischemic MMD (AHR, 2.13 [95% CI, 1.1-4.16]; P = .03).Conclusions and RelevanceThe findings of this cohort study of bypass outcomes for patients with MMD emphasize the importance of tailoring management strategies in adult patients based on onset types.

Abstract Natural lighting is the lighting obtained from direct sunlight, where the light is obtained in the morninguntil late afternoon.

High temperature corrosion via chlorine is a key factor in the degradation of boiler tubes in waste-to-energy (WTE) plants. Corrosion rates are particularly high in the superheater where material temperatures may exceed 450°C and where carbon or low alloy steels may be used. Although increasing sulfur, in the form of SO2, in WTE flue gas has been shown in previous works to have potential for decreasing the corrosion of these materials, the inhibitive effect is not well understood. This work investigated the corrosion of SA178A, a low carbon steel alloy (0.07 wt% C), and NSSER-4, a stainless steel (17.3Cr-13.1Ni-2.5 Si-Fe), via exposure under various well-defined environments, SO2:HCl ratios between 1:8 to 2:1 (HCl fixed at 800 ppm), 8% O2, 12% CO2, 0 and 15% H2O, N2 (balance) at 500°C in a horizontal tube furnace for 50 hours. Additional coupon testing was performed on NSSER-4 after application of 4 mg/cm2 ± 10% NaCl or Na2SO4 at 500 and 700°C for 24 hours to assess the impact of higher SO2 in the against both deposit and gaseous corrosion. Specimen preparation and corrosion assessment followed ASTM method G1-03. Experiments demonstrated little to no trends in corrosion rates at SO2:HCl ratios between 1:8–2:1 under mixed gas environment. However corrosion reduction was observed when SO2:HCl was increased from a reference condition of 1:8 to greater than 1.4:1 in tests with NaCl present, which was also not observed under dry conditions. These results suggest that one possible explanation for the reduction of boiler materials corrosion rate with higher concentrations of SO2 may be largely attributed to the conversion of metal chlorides to sulfates.

Over the past few decades, chromium contamination of both terrestrial and aquatic ecosystems has increased as a result of various anthropogenic activities. In this regard, various useful and practical remediation technologies have been emerging to control chromium content in water, soil and other resources. Chromium remediation through microorganisms may be the best technology currently available for cleaning up Cr contaminated sites. These technologies using biological agents are cheaper, safer and ecofriendly than chemical treatment methods. Cr exists in several oxidation states, but the most stable and common forms are Cr(0), Cr(III) and Cr(VI) species. Chromium toxicity depends on its valence state. Hexavalent chromium is a highly mobile and toxic contaminant. Cr(III) being less mobile is much less toxic than Cr(VI). The purpose of this study was to assess the potential of cyanobacterium Nostoc linckia to accumulate hexavalent chromium during three successive cultivation cycles on multimetallic systems. Cyanobacterium Nostoc linckia (Roth) Born et Flah CNM-CB-03 was grown in a mineral medium and metal ions in different combinations. Cultivation was carried out in Erlenmayer flasks of 1000 mL with a working volume of 700 mL. The following parameters were used: pH of the medium 6.8-7.2, temperature 25-27oC, light intensity of 37-55 μmol photons m-2 s-1, continuous illumination, slow periodic shaking. The amount of inoculum was 0.4 g/L. Each cultivation cycle lasted 12 days. Multimetallic systems Cr/Fe, Cr/Fe/Ni, Cr/Fe/Ni/Zn and Cr/Fe/Ni/Zn/Cu were added to culture medium on the exponential phase of nostoc growth. In this study, the bioaccumulation of Cr(VI) from multimetallic systems was performed - a situation that is closer to real conditions, since in most cases the contamination of certain areas occurs due to the presence of several pollutants. Among the four studied systems, in Cr/Fe, Cr/Fe/Ni, and Cr/Fe/Ni/Zn/Cu, the rate of chromium uptake by nostoc was very similar and varied with the cultivation cycle. Thus, in these three systems, chromium uptake in the first cultivation cycle was 35.8-40.2% of the initial level of metal; in the second cycle - 27.2-32.7%, and in the third cycle - 19.7-27.1%. In Cr/Fe/Ni/Zn system, the bioaccumulation capacity of nostoc biomass was significantly higher and amounted to 63.1%, 56.0% and 34.8% of Cr(VI), which corresponds to three cultivation cycles. Moreover, Fe, Ni, Zn and Cu were also taken up during the cultivation of nostoc biomass from one cycle to another. For instance, iron uptake in the first cycle was 59-78% and it was accumulated almost completely in the next two cycles. Nickel uptake in the first cycle was 43.2-62.6%, in the next two - 49.7-83.1%. The percentage of zinc recovery by nostoc biomass was at the same level in all three cycles and amounted to 37.1-39.8% of its initial content in the Cr/Fe/Ni/Zn system. In the Cr/Fe/Zn/Ni/Cu system, zinc uptake increased from 25.8% in the first cycle to 54.5% in the third one. Copper uptake was 46.5-57.8%, and its maximum amount was accumulated in the second cycle of nostoc cultivation. Thus, the culture of Nostoc linckia demonstrated resistance to multimetallic systems and a high potential for bioaccumulation of Cr(VI) and other metals present. The capacity of cyanobacterium Nostoc linckia to bioaccumulate Cr(VI) from the contaminated medium remained high over three generations, while the uptake of Fe, Ni, Cu and Zn in the biomass increased from generation to generation. In conclusion, edaphic cyanobacterium Nostoc linkia is a good accumulator of chromium, but also of other metals in multimetallic systems. Due to its biological nature, Nostoc linckia is a suitable matrix for remediation processes that offers a vast competition ground for metal cations. Therefore, the use of microorganisms for heavy metal removal is a sustainable remediation approach that must be adopted in order to balance the environment and nature.

Onunla energetika, nəqliyyat, hesablama texnikası, fizika, plazma, və s. kimi sahələrin inkişafı bağlıdır. Maqnit kəşfiyyatı, hidrodinamika, defektoskopiya, maqnit linzaları, informasiyanın maqnit yazılışı, suyun maqnit emalı-bütün bunlar maqnit sahəsinin sənayedə tətbiqinin yalnız bir hissəsidir. Maqnitoterapiyanın müalicəvi olduğu barədə təsəvvürlər hələ 16-cı əsrin əvvəllərinə təsadüf edir. Həkim-fılosof Sviss və əlkimyaçı Paraçels epilepsiya, qanaxma kimi xəstəlikləri məhz bu üsulla müalicə edirdilər. Lakin maqnit terapiyası 18-ci əsrin ortalarında Parisdə həkim Masmer-Avstraliyskiy (hipnozun əsasını qoymuş həkim, “hipnoz etmək” ifadəsi məhz onun adı ilə bağlıdır) tərəfindən “Maqnitlə müalicə” salonunun açılması ilə məhşurlaşdı. Elmi cəmiyyətlərin davam edən ittihamlarına baxmayaraq, maqnit terapiyası müalicə növü kimi kübar cəmiyyətində populyarlaşdı. 1799-cu ildə Eliza Perkins (həkim və heyvan ticarəti kimi iki müxtəlif sənətlə məşğul olub) insanda və atlarda bir sıra xəstəliklərin müalicəsi üçün metallik traktorlardan (traktor-paz şəkilli kiçik maqnitdir) istifadə etməyə başladı. Lakin 1799-cu ildə bu traktorlar doktor Perkinsin sarılıq xəstəliyindən vəfatının qarşısını ala bilmədi və bu da maqnit terapiyası əleyhdarları tərəfindən “reklam” kimi istifadə olundu. 1810-cu ildə Çikaqo maqnit kompaniyası tərəfindən xüsusi geyimlər - şlyapa və paltarlar satışa buraxıldı, (bu geyimlərdə 700-dən çox maqnit istifadə olunurdu). Kompaniyanın rəhbəri, doktor Tetçer, hesab edirdi ki, maqnit sahəsi bütün xəstəliklərin müalicəsi üçün yararlıdır. 20-cı əsrin əvvəllərində (elektrik cərəyanı kəşf olunandan sonra) doktor Albert Abrams elektromaqnit dalğalarının müalicəvi olduğunu kəşf etdi. İkinci dünya müharibəsi zamanı elektromaqnit sahəsinin təkrarsız effekti yaralı Amerika əsgərlərinin ağrılarının azaldılmasında, yaraların sağalmasının sürətlənməsində tətbiq edildi. Gün ərzində günəş pozitiv (+) maqnit enerjisi buraxır, lakin gecə təbii mənfi maqnit sahəsi toxumalar tərəfindən oksigenin qəbulunu artıraraq dərin yuxunu təmin edir, bioloji sağalmaya kömək edir, ağrını azaldır. Gün ərzində günəşin müsbət maqnit enerjisi ümumilikdə mənfi təsir də edə bilər. Maqnit məhsulları orqanizmin terapevtik mənfi maqnit sahəsini bərpa etmək və ya olan maqnit sahəsini gücləndirmək məqsədi ilə tətbiq olunurlar (1).
