In an effort to improve electricity services to customers, there needs to be a balance between the supply of electricity and revenue. Payment methods made by the Perusahaan Listrik Negara (PLN) use Postpaid and Prepaid methods. Because services with postpaid methods better meet customer satisfaction, this method is chosen. Sales Accounting Information System is an information technology-based accounting application to support financial transactions in a company to run faster, more precisely and accurately at a reasonable cost. In its operation, it takes competent human resources to not be a source of problems (human error) and adequate infrastructure. To overcome the obstacles that will arise, whether triggered by the application or by the human resources themselves, it is necessary to control both aspects. Based on this research it shows that the application  of  Sales Accounting Information Systems and existing human resources is sufficiently supportive  and  reliable  in  supporting the creation of good control as it is proven that the level of acceptance of sales targets is realized effectively and efficiently.

Background: The aim of the study was to compare the hemoglobin levels among normal controls (patients) and patients of TypeII diabetes with HbA1c levels below 7 % & above 7 %.and secondly to identify the undetected cases of anemia in TypeII diabetes. Materials & Methods - 50 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels less than 7 %, 50 patients of type 2 diabetes mellitus with their glycosylated hemoglobin levels more than 7 % attending the Medicine outpatient department of Subharti Medical College and Hospital will be the subjects for the study.50 age and sex matched controls will be selected randomly from Subharti Medical College and Hospital. Informed written consent will be taken from all the subjects. The study will be conducted from January 2016 to January. Result - We studied 50 cases with HbA1C>7(poor control),50 cases with HbA1C 5.6 to7 (good control) and 50 controls with HbA1C ≤5.6, we observed in cases with HbA1C>7 (poorly control) ,the mean HbA1C is 9.9±2 and mean Hb is 9.8±1.3 as compared to cases with HbA1C 5.6 to 7(good control) where mean HbA1C is 6±0.4 and Hb is 13±0.5,this clearly indicates that in cases HbA1C is more Hb levels are low and when HbA1C is less Hb levels are higher. Conclusion - In the present study we found negative correlation between HbA1c & Hb levels. As the value of HbA1c increases, as in cases of HbA1c >7(poor diabetic control), we found low Hb levels as compared to the cases with HbA1c <7(5.6-7) (good control).

In past work, dichloropropene + 17% Pic (1,3-D + Pic) at 327 L·ha–1 plus pebulate provided good control of nematode, soil fungi, and nutsedge in mulched tomato (Lycopersicon esculentum Mill.) and is considered the best alternative for methyl bromide (MBr) + chloropicrin (Pic), which is scheduled for phase-out in the United States by Jan. 2001. Metam-sodium did not provide acceptable pest control. In the present study, metam-Na (295 L·ha–1 combined with Pic (168 kg·ha–1) + 4.5 kg·ha–1 pebulate, and 1,3-D + 35% Pic at 168 and 225 L·ha–1 + pebulate were compared to MBr-Pic (98-2% at 345 kg·ha–1 and 67-33% at 505 kg·ha–1). Fumigants were injected into the bed except metam-Na and pebulate were surface-applied and incorporated and drip tubing and mulch were applied. Marketable yields with MBr-Pic, 225 L·ha–1 1,3-D + Pic, and metam-Na + Pic were higher than with the check. Yields with metam-Na alone or with additional water before transplanting were similar to the check. Nutsedge was controlled with MBr-Pic and all treatments with pebulate. Nematode root-gall ratings were high on tomato grown without fumigants (8.9 rating on a scale of 0 to 10 with 0 = no galling), low with MBr-Pic (0.33), and intermediate with all other treatments (2.2 to 5.5) except with 168 L·ha–1 1-3-D + Pic (8.3). This study indicates that metam-Na + Pic + pebulate also is a possible alternative to MBr-Pic for tomato.

Abstract There is increasing evidence of specific medical and psychological benefits associated with humor within diabetes populations. The benefits of maintaining good diabetes control are also well established. The more general relationship between humor and diabetes control however remains unexplored. The purpose of this study was to examine if there was a difference between people with diabetes with an A1C ≤ 6.99% versus those ≥7.0% on four disparate types of humor. The sample consisted of 284 participants, 65.5% with type 1 diabetes, 68.3% female, 89.1% Caucasian, and 68.7% college educated. Participants completed the Humor Styles Questionnaire (HSQ) and were divided into two groups, A1C ≤ 6.99% and A1C ≥ 7.0%. The A1C ≤ 6.99% group scored significantly higher on both types of positive humor, affiliative humor (P < 0.01) and self-enhancing humor (P < 0.05). There was no significant difference between participants on either type of negative humor, aggressive humor (P > 0.05) or self-defeating humor (P > 0.05). Results indicate that good control (A1C ≤ 6.99%) is associated with positive humor. These findings provide evidence that there is an association between American Diabetes Association recommended levels of control and positive humor styles. Implications regarding positive humor and good diabetes control are discussed.

ObjectivesTo determine the prevalence of diabetes mellitus (DM), prevalence of diabetic retinopathy (DR) and sight-threatening conditions among persons with DM aged 50 years and older in Sohag governorate in Upper Egypt.DesignPopulation-based, cross-sectional survey using the standardised Rapid Assessment of Avoidable Blindness with the addition of the Diabetic Retinopathy module methodology.SettingsSohag governorate in Egypt where 68 clusters were selected using probability proportional to population size. Households were selected using the compact segment technique.Participants4078 people aged 50 years and older in 68 clusters were enrolled, of which 4033 participants had their random blood sugar checked and 843 examined for features of DR.Primary and secondary outcomesThe prevalence of DM and DR; secondary outcome was the coverage with diabetic eye care.ResultsThe prevalence of DM was 20.9% (95% CI 19.3% to 22.5%). The prevalence in females (23.8%; 95% CI 21.4% to 26.3%) was significantly higher than in males (18.9%; 95% CI 17.1% to 20.7%) (p=0.0001). Only 38.8% of persons diagnosed with diabetes had good control of DM. The prevalence of DR in the sample was 17.9% (95% CI 14.7% to 21.1%). The prevalence in females was higher (18.9%; 95% CI 14.0% to 23.8%) than in males (17.1%; 95% CI 13.0% to 21.2%). Up to 85.3% of study participants have never had eye examination. Sight-threatening DR (R4 and/or M2) was detected in 5.2% (95% CI 3.4% to 7.0%) with only 2.3% having had laser treatment.ConclusionThe prevalence of uncontrolled DM in Sohag governorate in Egypt is higher than the national prevalence. There is a high prevalence of sight-threatening retinopathy and/or maculopathy with few people having access to diabetic eye care. A public health approach is needed for health promotion, early detection and management of DR.

Background: The COVID-19 pandemic contributes to the burden of living with different diseases, including Systemic Lupus Erythematosus (SLE). We described, from a narrative point of view, the experiences and perspectives of Italian SLE adults during the COVID-19 emergency, by distinguishing the illness experience before and after the lockdown. Methods: Fifteen patients were invited to participate. Illness narratives were collected between 22 and 29 March 2020 using a written modality to capture patients’ perspectives before and after the COVID-19 lockdown. We performed a two-fold analysis of collected data by distinguishing three narrative types and a qualitative analysis of content to identify the relevant themes and sub-themes reported. Results: Eight narratives included in the final analysis (mean length 436.9 words) have been written by eight females (mean age 43.3 ± 9.9 years, mean disease duration 13.1 ± 7.4 years). Six patients provided a quest narrative, one a chaos and the remaining one a restitution narrative. By text content analysis, we identified specific themes, temporally distinct before and after the lockdown. Before COVID-19, all the patients referred to a good control of disease, however the unexpected arrival of the COVID-19 emergency broke a balance, and patients perceived the loss of health status control, with anxiety and stress. Conclusions: We provided unique insight into the experiences of people with SLE at the time of COVID-19, underlining the perspective of patients in relation to the pandemic.

Laser-deposited gold immobilization layers having different porosities were incorporated into love wave surface acoustic wave sensors (LW-SAWs). Variation of pulsed laser deposition parameters allows good control of the gold film morphology. Biosensors with various gold film porosities were tested using the biotin–avidin reaction. Control of the Au layer morphology is important since the biotin and avidin layer morphologies closely follow that of the gold. The response of the sensors to biotin/avidin, which is a good indicator of biosensor performance, is improved when the gold layer has increased porosity. Given the sizes of the proteins, the laser-deposited porous gold interfaces have optimal pore dimensions to ensure protein stability.
