The Emerging Role of Public Health Leadership in Food Systems Transformation
Authors: L. Slimko Michelle
Published: September 2022

Food systems and dietary patterns are inextricably linked to public and planetary health. These relationships are becoming more apparent every day, as the need to produce enough food to nourish a growing global population is impacted by issues such as pandemics, climate change, and biodiversity loss. These are just a few of the challenges impacting public health, and each will require continuous transformations to programming and practice to keep us moving towards healthier and more sustainable food systems. Fortunately, there is a growing number of decision-makers dedicating themselves to addressing these issues, from local grassroots efforts to international initiatives. Although the approaches may differ drastically between groups, the end goals of protecting the planet and its inhabitants are a universal theme. At present, no entity knows exactly how to solve these complex and interconnected issues between health and sustainability, but it is clear that a “business-as-usual approach” may not be enough. The ability of DrPH leaders to facilitate collaboration (both within and across scientific disciplines, institutions, and industries) can be a key lever of change for food system transformation, as can be their ability to recognize and amplify the voices of those promoting the most promising evidence-based solutions and programming strategies. DrPH leaders should have ample opportunities to utilize their unique skillsets to redefine their roles within the larger context of food systems science and sustainability.

An expansive body of literature confirms the existence of health inequities in the United States (U.S.), disadvantaging communities of color. These inequities reach beyond medical causes; they are the direct result of unjust sociocultural, behavioral, economic, environmental, and societal inequalities. Health inequities are perpetuated by centuries of bias and discrimination that continue to persist, especially toward communities of color. To address health inequities, Doctor of Public Health (DrPH) students have a role and responsibility to be a nexus for systems-level change across public health practice, research, and education. DrPH students can make significant contributions through research, education, and practice, and lead advocacy efforts within their institutions for the decolonization of public health. Decolonization in public health can occur through the creation of new paradigms for funding agencies and training DrPH students as scholar-activists in ways that ground research, education, practice and dissemination in partnership with communities. A deeper and adaptive understanding of inequities and the needs and resources required along with a collaborative and collective effort across the entire public health system could inspire community-based policies and improve public health interventions.

Published: September 2022

The public health workforce is dependent on well-trained and diverse professionals that possess the necessary knowledge, competencies, and leadership to advance the field of public health and address the urgent and persistent problems faced by individuals and communities. Communities that have been historically marginalized and disadvantaged rely on respected and trusted leadership willing to understand and confront the vestiges of enduring racist cultural perceptions and beliefs that prevent optimal and equitable health and healthcare. DrPH programs have created opportunities for students to gain foundational and concentration-specific competencies and leadership to apply their learning towards research, intervention, and policy solutions that transform health inequalities leading to health equity.

Authors: Omar Aliyu Abdulhamid , Dalhatu Abdulrasheed , Kafi Shehu Abubakar , Aliyu Umar
Published: September 2022

The study investigated the abundance and diversity of mosquito species larvae in different larval breeding habitats of Azare, Katagum L.G.A., Bauchi State, Nigeria. The selected habitats were surveyed weekly between August and October, 2021 across ten communities. A total of 2,320 mosquito larvae of different instars were collected and reared to adults in which 1,624 successfully emerged as adults comprising of three genera namely: Anopheles 464 (20%), Culex 928 (40.00%) and Aedes 232 (10%). A total of four (4) species were identified; two (2) of which were Anopheles spp. (An. gambiae and An. arabiensis), one (1) Culex spp. (Cx. quinquefasciatus), one (1) Aedes spp. (Ae. aegypti); while the numbers of unidentified individuals for Culex and Aedes genera down to species level were one (1) species for each respectively. The results of this study found high species abundance and relatively low diversity but a high larval breeding index. There was no significant difference (p > 0.05) in larval abundance among the three groups. Most interestingly, the study found out that mosquitoes’ larvae co-habit together in relation to the breeding habitats sampled across the study area. The results of this study signify high transmission risk of mosquitoes-borne diseases in the area. Thus, control interventions, to reduce malaria burdens and other arboviruses, in the city should be broadened to target the breeding sites of mosquitoes by implementing a larviciding strategy especially during the wet season is presumably the most cost-effective strategy to consider.
Studies on seed source variation in Albizia lebbeck (L.) Benth.
Authors: Bahar Nawa
Published: September 2022

Source variation study of Albizia lebbeck was undertaken to identify the superior seed sources for production of quality seedling. Twenty nine seed sources sampled from the greater part of its natural range. Variation for most of the studied characters indicated non-clinal pattern. On average, the population of Dehra Dun (Uttarakhand), Kathua (Jammu & Kashmir) and Tirunelveli (Tamil Nadu) were found to be the best on the basis of weight, germination percent and vigour index of seed as an important criterion for delineating the superior seed source. This preliminary investigation will be useful for further improvement of the species for better productivity.
Structure of Mahogany (Swietenia macrophylla King) fruit, seed and their characteristics
Authors: Kader S. , Seethalakshmi K.
Published: September 2022

The fruit is a large (12.90–15.40 cm length x 8.74–10.64 cm diameter, excluding the capsule stalk), erect woody capsule. There are five outer thick and five inner thin valves. There is a central axis, the columella, which is typically 5-angled to which the seeds are attached pendulously by their wings. The mean weight of a capsule was 369.47 (± 54.01) g, ranging between 231.13 (± 25.67) g and 565.55 (± 72.82) g. On average a capsule contains 43 germinable seeds. One thousand fresh seeds (with wings) weigh from 607.06 g to 919.15 g. Significant differences existed between locality. Capsules collected from Karulai were found to be larger in size when compared to those collected from other localities. Seeds are winged and dark brown coloured. Longitudinal section of a seed revealed that the seed consists of a minute embryo embedded peripherally at one side within the massive cotyledons which is surrounded by a white thin testa which is again covered by dark brown coloured spongy tail-like wing. The variation in seed weight, germination percentage and germination period could be due to provenance differences, size of capsules, crown size of parent trees, level of seed maturity, site fertility, health condition of parent trees and environmental factors of a locality. The selection of parent trees having larger capsules appears to be most promising for seed collection.

Published: September 2022

In the end of the year 2019, a new strain of virus, named as COVID-19 was identified in the Wuhan city of China. As there are no specific treatment of drugs available in the market, people are searching for new drugs for combating COVID-19 disease. In our current research work, we have taken main protease (Mpro) as the receptor molecule (PDB ID 6LU7) and performed molecular docking study with various ligands like quercetin, chalcone, flavanone, hinokiflavone, isoflavone, robustaflavone, salannin, nafamostat and nimbosterol to understand the the mode of interaction which is helpful for designing new drugs for treating the virus. We have also done ADME (Absorption, Desorption, Metabolism and Excreation) property studies of the respective ligands. Our studies reveal that robustaflavone is the best potent inhibitors against the COVID-19 virus. However further researches are needed to investigate their potential medicinal use.
Synthesis of ZnO nanoparticles at room temperature with enhanced ultra‐violet photoluminescence

Published: September 2022

ZnO nanoparticles (NPs) have attracted a lot of attention due to the possibility of their applications in different fields including optoelectronics, photonics, biosensing, catalytic, etc. Most of the applications require devices made of good quality of NPs. However, synthesis of device grade NPs is always challenging. Here, improvement of crystalline quality of the ZnO NPs has been demonstrated with a very simple procedure. ZnO NPs of average crystallite size of ~11.5 nm with optical band gap of ~3.44 eV have been synthesized in room temperature following the co-precipitation method by either varying the concentration of KOH or time of synthesis. For both the cases, change in average size of NPs has not been found to change significantly. This is mainly because the required heat energy to grow the size has not been provided externally. However, the increase of concentration of KOH or time of preparation has been found to improve the quality of the ZnO crystallites. The improvement of crystalline quality has been argued as due to the availability of enough KOH or the time to repair the defects on the surface of the NPs. Improvement of crystalline quality has been found to result in an enhancement of intensity of the ultraviolet (UV) photoluminescence (PL) emission band over the visible PL emission band of ZnO. The defect mediated visible PL emission is always considered as loss. The enhancement is ~2-fold. Such large enhancement can be utilized for the fabrication of optoelectronic devices and others based on ZnO NPs synthesized at room temperature.

Published: September 2022

The Department of Education (2021) states that inclusive education encourages diversity and the unique contributions of each student in the classroom. The goal of making, testing, and using the Inclusive Learning Activity Sheet (ILAS) to teach hard chemical concepts is to help STEM students improve their academic potential as independent learners in hard chemistry lessons. The foundation of the study is set by social constructivism (n.d.) and Process-Oriented Guided Inquiry Learning (POGIL, 2018). The cross-method triangulation technique is used to collect and analyze data in this quasi-experimental study. Three evaluation stages, a pre-test, a post-test, and a retention test, were conducted, and an adapted DepEd-LMRDS validation instrument was used to ensure the quality of the ILAS as SLMs for General Chemistry 2. There were twenty-eight (28) STEM student participants who were purposefully sampled and five (5) expert ILAS validators involved in this study. Before the study was conducted, participants read and signed a consent form outlining the nature, goal, and methodology of the research. Participants were guaranteed confidentiality and anonymity in the study report (Creswell, 2020). According to the findings, the created ILAS for General Chemistry 2 demonstrated a highly acceptable (HA) measure based on the five acceptance criteria of LMRDS. There was a significant rise in the number of students with outstanding performance in General Chemistry, from 25.00 percent on the pretest to 57.14 percent on the retention test. The ILAS for General Chemistry 2 helps STEM students improve their grades and remember what they’ve learned in a statistically significant way. To keep education fair and high-quality for all students, it is recommended to change and build self-learning resources for different classes in every subject that have been carefully tested by experts.

This study examined the influence of Science engagement and learning interaction of Grade 7 online learners’ acquisition of 21st-century skills and Science achievement. Seventy-six (76) Grade 7 online learners of San Pablo City Integrated High School served as respondents of the study to find a correlation between 21st-century skills (communication) and Science achievement in student-teacher interactions using descriptive and inferential statistics. Accordingly, findings revealed that student-teacher interaction is a significant mediator in the relationship between Science engagement and Science achievement. The correlation results showed that the perceived online Science engagement (cognitive, affective/emotional, and behavioral) and learning interaction (student-student, student-content) have no significant relationship to the acquired 21st-century skills (critical thinking, creativity, and communication) and Science achievement of the respondents. More, so that student-teacher interaction significantly influences Science engagement. The presence of the teacher does influence learner’s outcome in acquiring 21st-century skills.. The mediated variable, learning interaction (student-teacher), partially mediated the influence Science engagement has on Science achievement. Thus, considering the study’s findings and conclusions, it is recommended that schools must invest in online learning environments that improve learning and teaching outcomes. Enable online engagements, and stimulate connections with peers, teachers, and the institution. Foster Science and 21st-century skills, add student online engagement and learning interaction data that can guide school-wide activities, and lastly have multiple sources to facilitate a more profound understanding among online students.

Teachers in the Philippines have closed shifted to online learning, have more needs in teaching, and face several obstacles as a result of the COVID-19 epidemic. The goal of this descriptive correlational research is to identify teachers’ needs and challenges during this pandemic. According to the findings, a teacher’s priority needs during a pandemic were books as teaching and learning resources to integrate content into my instruction; video gadgets for learners to practice; and audio-learning instructional materials. In times of pandemic, the most difficult challenges for K-12 teachers were improving learning outcomes, adhering to COVID-19 safety protocols, and inspiring learners to be more self-directed. Finally, there was a strong link between teachers’ needs and challenges during pandemics. This demonstrates that when the needs were high, so were the challenges. It is suggested that DepEd officials and school principals prepare for future emergencies by developing clear emergency plans and fitting online mechanisms and training into current face-to-face classes and teacher professional growth.

Managing Solid Waste at Isabela State University Cabagan (ISUC) Campus: Current Practices and Unfolding Opportunities
Authors: Peñaflor Bondee , B. Ong Heherson
Published: September 2022

Solid waste is a pressing environmental concern nowadays. Even academic institutions are not exempted on its associated problems. To this end, the practices and implementation schemes of ISUC in addressing the concerns on solid wastes were assessed. Through individual interviews, actual field observations/validations, and desk review of documents, several qualitative data were generated categorized, summarized and analyzed through content analysis. Results show that in so far as solid waste and its management is concern, the following key issues/concerns were identified: absence of an approved long-term SWM Plan; source of funding support for SWM programs; lack of manpower in implementing the SWM programs; no segregation/reduction of wastes at source; collection system needs to be revisited/changed; open burning and littering of wastes; recovery facilities need improvement; functionality of SWM equipment; and IEC campaign materials. In terms of SWM initiatives, the campus has existing institutional arrangements on dealing with solid wastes concerns. It also has various equipment and manpower to cater the needs for SWM. Source reduction and segregation-at-source are also given attention including collection system but not fully functional/operational. There are also existing recycling initiatives and marketing of recyclables/saleable materials. As to disposal, the special/hazardous wastes from laboratory and health offices are stored in the septic vault beside the campus’ Centralized Materials Recovery Facility. In addition, scientific studies were conducted vis-à-vis SWM. However, complementary activities need to be made in place which include: strengthening IEC campaigns; attendance to SWM capacity-building programs; and the adoption of a comprehensive campus-based SWM Framework

Published: September 2022

Background: Digitalization of healthcare led to the optimization of monitoring, diagnostics, and treatment of the range of disorders. Taking into account recent situation with COVID-19 pandemics, digital technologies allowed to improve management of viral infections via remote monitoring and diagnostics of infected patients. Up to date, various mobile health applications (apps) have been proposed, including apps for the patients diagnosed with cardiovascular pathologies. Objective: The presented review aimed at the analyses of a range of mHealth solutions used to improve primary cardiac care. In addition, we studied the factors driving and hindering the wide introduction of mHealth services in the clinics. Methods: The work was based on the guidelines of the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. The publication search was carried out using PubMed, Web of Science, Cochrane Library, Scopus, and Google Scholar databases. Studies published during the period from 2014 until January 2022 were selected for the analysis. The evaluation of risk of bias for the included studies was conducted using the Cochrane Collaboration Risk of Bias tool. Results and Discussion: An overall 5513 studies were assessed for eligibility after which 39 studies were included.. The main trend in the mobile health for cardiological applications is the use of different types of wearable devices and Artificial Intelligence-platforms. In fact, mobile technology allows remotely to monitor, interpret, and analyze biomedical data collected from the patient. Conclusion: The results of this literature search demonstrated that patients diagnosed with cardiovascular disorders can potentially benefit from the application of mHealth in cardiology. However, despite the proven advantages of mHealth for cardiology, there are many challenges and concerns regarding effectiveness, safety, reliability and the lack of official regulation and guidelines from official organizations. Such issues require solutions and further work towards a wide implementation of mHealth technologies in cardiac practice.

Authors: Attia Zeinab , Abdelazem Hala , Nada Iman
Published: September 2022

The effect of hypoxia and reoxygenation on Nile tilapia (Oreochromis niloticus) was studied. The fish were exposed to hypoxic oxygen concentrations (2 and 0.5 mg O2 L-1) for 1 day (short term) and 30 days (long term) followed by reoxygenation for 1 day and 7 days, respectively. The activities of superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) significantly decreased in the gills of all the hypoxic groups after both short and long term of hypoxia exposures, while increased significantly below control levels after reoxygenation except that the activities of SOD and GST in the reoxygenated groups pre-exposed to short-term (2 mg O2 L-1), SOD activity in the reoxygenated group pre-exposed to long-term (0.5 mg O2 L-1), and the activities of CAT and GST in all the reoxygenated groups pre-exposed to long-term hypoxia, had no significant change compared to their respective hypoxic groups. The activities of glutathione peroxidase (GPx), glutathione reductase (GR) and xanthine oxidase (XO) significantly increased during hypoxia then decreased significantly after reoxygenation except for GPx activity in the reoxygenated group pre-exposed to short-term (2 mg O2 L-1). Malondialdehyde (MDA) concentrations significantly increased in all the hypoxic and reoxygenated groups compared to their respective controls. The significance of these alterations in enzyme activities and oxidative stress indices is discussed. In conclusion, hypoxia and subsequent reoxygenation induce oxidative stress in Oreochromis niloticus gills causing depletion of some antioxidant enzymes. Long-lasting oxidative stress can delay full recovery.

Published: September 2022

Introduction: Renal cell carcinoma (RCC) has varied presentations and outcomes. TNM Stage, pathological features and performance status are the established factors prognosticating the disease. Recently, role of thromobocytosis has been evaluated as simple, cost effective and accurate prognostic marker in RCC patients.

Objective: To study the effect of thromobocytosis in renal cell carcinoma on prognosis of disease.

Materials And Methods: A retrospective observational follow-up study of 142 patients with RCC from January 2007 to December 2017 was conducted at Institute of Nephrourology, Bengaluru (Karnataka). Platelet count more than 400000/mm3 was considered as thrombocytosis. The clinical parameters, tumour stage, grade, progression and survival of the disease were compared with respect to platelet count. Mean follow-up was 28 months (24-60 months). Patients time to disease progression and overall survival were studied with regard to thromobocytosis. Data was analysed using SPSS V26.0 using Chi square test, binary logistic and linear regression model and Kaplan Meir curve.

Results: Mean age was 54.59 years. Mean platelet count was 2, 45,292 /mm3 and mean tumour size was 7.67cm. Thromobocytosis correlates with total leucocyte count (p value <0.001), tumour necrosis (p value 0.04), lymph node invasion(p value 0.01), metastasis( p value 0.027), TNM stage(p value <0.001) and overall survival(p value <0.001). These patients also had poor histology and more lymphovascular invasion. On regression analysis only TNM stage correlates significantly (p value 0.01) with time to progression. Platelet count >400000/mm3 was associated with poorer survival outcomes with 5-year mortality rate of 38%.

Conclusion: Thrombocytosis in RCC is associated with advanced disease, poor histology and rapid disease progression. It is simple and easy tool for prognosticating RCC and predicting survival outcomes.

Authors: Siska Siska , Sukmawati Ni , Jayanegara I , Triningrat AA , Manuaba IB
Published: September 2022

BACKGROUND: Conditions such as posterior capsular rupture, pseudoexfoliation syndrome, high myopia or Marfan's syndrome may cause inadequate posterior capsule support. Implantation of an anterior chamber IOL , iris-sutured IOL, scleral fixation IOL, or iris-claw IOL may be considered in these conditions. Iris-claw implantation is often preferred due to its convenience and timesaving in use but the visual outcomes in Prof Ngoerah General Hospital has not yet published.
MATERIAL AND METHODS:. This retrospective observational study was aimed to determine the characteristics and outcomes of iris-claw (Artisan) IOL implantation. Data was obtained before, after one week and 30 days implantation at Sanglah Hospital from August 2019-July 2022. Patient characteristics were analyzed with descriptive analysis and presented as frequency, percentage, mean and standard deviation. The differences between visual acuity, intraocular pressure and endothelial cell count were analysed using paired T-test and Wilcoxon signed rank test.
RESULTS: This study consisted of 21 eyes with the mean age was 45,38±25,86 years. The most common primary procedure was caused by secondary aphakia in 6 (28,6%) patients and lens subluxation and zonular weakness (due to high myopia) in 5 patients (23,8%). A total of 13 (61,9%) were implanted in the prepupillary. There was a significant increase in visual acuity from 1.69 ±0.76 logMAR to 0.50±0.33 logMAR after one week and constantly increase from one week to 0.37±0.27 after 30 days follow up (p=0.046). The complication reported was one patient (4,7%) with temporary increasing intraocular pressure. Spherical residual were mostly under -1.0 D (57.1%) and cylindrical residual were 9 (42.8%) less than -0,50D. Endothelial cell density were decreasing 2.1% from 2673.81 (948) cell/mm2 to 2616.9(800) cell/mm2 but the reduction were not statistically significant (p=0.192). There was no difference of intraocular pressure before and after implantation (p=0.638).
CONCLUSION: This study showed that the implantation of iris claw lens were safe, has faster recovery and effective for either primary or secondary procedure.
Acyclovir Induced Neurotoxicity in Patients With Chronic Kidney Disease
Authors: KUMAR ALOK , Khrime Dorchhom
Published: September 2022

Acyclovir is highly useful for treatment of herpes virus infection. It is excreted primarily by kidneys. Therefore it gets accumulated in patients with renal dysfunction. There are reports to suggest that acyclovir usage could lead to neurotoxicity characterized by disorientation, decreased level of consciousness, dysarthria, tremors, seizures, hallucinations and coma. Acyclovir induced neurotoxicity has been found with patients on dialysis or not on dialysis. We present here five cases of CKD who developed neurotoxicity after use of acyclovir for herpes zoster. They had disorientation, decreased level of consciousness, dysarthria, tremors, seizures and hallucinations 2-4 days after administration of acyclovir. Acyclovir induced neurotoxicity was suspected because we could not find any other cause for neurological symptoms in these patients. Acyclovir was discontinued in all cases and haemodialysis sessions were given. One patient was managed by increasing number of exchanges of peritoneal dialysis. All patients recovered in 3-5 days after discontinuation of drug. Main factors for acyclovir induced neurotoxicity are advance age , renal failure, inappropriate dose of acyclovir in relation to creatinine clearance. Acyclovir induced neurotoxicity should be suspected in patients with renal dysfunction those present with neurological symptoms 2=4 days after taking of drug. These patients should be treated with discontinuation of acyclovir and judicious use of haemodialysis. Physicians should adjust the dose of acyclovir according to creatinine clearance to minimize toxicity.
Lower urinary tract dysfunction in diabetes mellitus: the forgotten disease
Authors: Araujo Raquel , Melo Bruna , Ribeiro Margarida , o Ana , Andrade Maria
Published: September 2022

Diabetic cystopathy is a common complication in patients with diabetes mellitus. It may cause a variety of manifestations ranging from bladder hyperactivity to decreased bladder contractibility. However, the presence of bladder dysfunction in diabetic patients is often underdiagnosed by clinicians.
We present a case report of a 54-year-old woman with a medical history of diabetes with recurrent lower urinary tract infections and pyelonephritis. Her bladder dysfunction was never assessed until she was admitted to our department. We identified an impaired sensation of bladder filling and an inability to voluntarily contract the detrusor. We provided pharmacological treatment to enhance bladder emptying and proposed a new bladder-emptying regimen.
The patient remains with this therapeutic strategy with no evidence of further complications. This case aims to raise awareness among clinicians about diabetic bladder dysfunction.

Published: September 2022

Fat embolism syndrome is an infrequent entity, of which its pathophysiological mechanism is not clear. It occurs as a complication of long bone fractures or high energy trauma. Its presentation is insidious, which is why it is underdiagnosed and the clinic must be correlated with the imaging findings to identify it. We present a case report of a patient with fat embolism with the purpose of characterizing the symptoms, as well as the imaging findings that may occur during the course of the disease in these patients. It is of great importance to recognize the imaging signs that may occur and not rule out the pathology in the absence of these since they do not always appear.

Introduction: Lymphoma is a group of lymphoproliferative malignancies that can originate in B lymphocytes, T lymphocytes, or natural killer (NK) lymphocytes. They account for 3% of all cancer types. The WHO's 2008 World Health Organization (WHO) classification of hematopoietic and lymphoid tumors was refined in 2016. This study screened surgically excised or biopsied specimens for lymphoma in lymphadenopathy. This research aimed to classify lymphomas in India based on histopathological and immunohistochemical findings.
Methods: The study included 71 cases suspected/probable/proven to have lymphomas and H and E-suggestive lymphoid malignancies were recruited. Clinical details, histopathological reports, and lymphoma panel IHC status were analyzed. Age, sex, biopsy site, B-symptom history, and clinical findings were recorded. Paraffin blocks were prepared from biopsy specimens in buffered formalin using standard automated methods. All cases' slides were examined to confirm lymphoma. Tissue blocks were selected for IHC staining. All the slides were evaluated and classified as per the WHO 2016 lymphoma classification.
Results: The mean age of the patients was 44.58 years, and 54 patients were males, while 17 were females. 61 of 71 cases were detected to be of NHL and 10 cases were of HL. The majority of NHL cases were formed by B cell neoplasms, constituting 72.1%, whereas T cell neoplasms constituted 24.6%. 2 of 61 cases showed CD56 positivity apart from T-cell markers and were categorized as T/NK cell NHL. As per WHO classification, different types of NHL and HL were classified. Among NHL, follicular lymphoma (FL) was predominant with 15 cases, while in CHL, mixed cellularity CHL prevalence was high. Ki67 expression in 15 cases of FL showed 1 case of grade 1, 3 cases of grade 2 and 2 cases of grade 3 follicular lymphoma with a Ki67 index of more than 40%.
Conclusion: Histomorphology and immunohistochemistry helps diagnose lymphoma. NHL was more common among nodal and extranodal lymphomas. The NHL and HL were dominated by men. Follicular lymphoma (FL) was the most common subtype of B-cell NHL. Most HL patients had mixed-cellularity CHL.

Hiện nay, các công ty đã bị một làn sóng chảy máu chất xám như các kỹ sư đã lần lượt ra đi không gắn bó với công ty nữa, đa số là chuyển công tác đi các công ty khác, hoặc chuyển làm ngành nghềkhác, trái nghề. Do đặc điểm công việc của các kỹ sư xây dựng: công việc đòi hỏi tính tự chủ cao, phức tạp, áp lực lớn, do tiến độ công trường. Điều kiện làm việc không tốt thường xuyên xa nhà, làm việc ở vùng sâu vùng xa, ăn ở tạm bợ, phương tiện đi lại khó khăn, áp lực nghề xây dựng ngày càng cao, các kỹ sư phải có năng lực chuyên môn cao để giải quyết những rủi ro phát sinh trong dựán. Việc tăng ca, số giờ làm việc với cường độ cao 12h-14h một ngày đối với kỹ sư xây dựng là công việc trở nên bình thường. Ngành xây dựng đóng vai trò quan trọng nhưng không còn tạo ra sức hút đối với người lao động bao gồm người học trong chọn nghề nghiệp, điều đó dẫn đến thiếu hụt lao động nghiêm trọng. Do đó các công ty cần phải có chính sách thu hút và giữ chân nhân viên.

Cọc xi măng đất (CXMĐ) ngày càng phổ biến và được sử rộng rãi trong việc gia cố nền đất yếu, đặc biệt tại khu vực đồng bằng sông Cửu Long. Phương pháp nén đơn trục trong phòng được sử dụng trong nghiên cứu này nhằm đánh giá cường độ chịu nén của cọc xi măng đất. Kết quả nghiên cứu cho thấy hàm lượng XM/Đ ít nhất từ 300 kg/m3 trở lên được xem là phù hợp với địa chất yếu tại khu vực nghiên cứu. Ngoài ra, tỷ lệ cường độ chịu nén của cọc xi măng đất ngoài hiện trường so với trong phòng thí nghiệm tại các khu vực nghiên cứu nằm trong khoảng (0,32÷0,96). Điều này cho thấy phương pháp thi công CXMĐ (jet-grouting) đảm bảo chất lượng với hệ số tương quan cao hơn so với hệ số được đề nghị trong tiêu chuẩn hiện hành.

Mục tiêu của tính toán thủy lực mạng lưới thoát nước mưa là để xác định được các thông số kỹ thuật như đường kính, độ dốc, vận tốc... cho các đoạn cống và các công trình liên quan với yêu cầu đạt hiệu quả cao nhất về kinh tế, kỹ thuật và quản lý vận hành toàn hệ thống. Để đạt được mục tiêu này, người thiết kế, trước hết phải lập và mô phỏng được sát thực nhất những diễn biến thủy lực trên mô hình giống như diễn biến của nó ngoài thực địa, sau đó tiến hành phân tích, đánh giá và điều chỉnh để xác định được một mạng lưới tối ưu nhất, đồng thời xây dựng những kịch bản sẽ xảy ra trong tương lai nhằm kiểm soát, hạn chế rủi ro. Một trong những yếu tố để đảm bảo cho công tác tính toán, mô phỏng thủy lực mạng lưới đạt yêu cầu là phải xác định được đúng, đủ các loại tổn thất năng lượng dòng chảy. Hiện nay trong tính toán thủy lực mạng lưới thoát nước mưa đô thị ở Việt Nam, người thiết kế hoặc cho rằng tổn thất cục bộ tại ga chiếm tỷ lệ nhỏ so với tổn thất ma sát dọc tuyến nên bỏ qua hoặc là lấy hệ số tổn thất gần đúng theo những điều kiện giả định mà chưa có những cơ sở khoa học rõ ràng để xác định thành phần này và tất nhiên là kết quả tính toán, mô phỏng cũng chưa đạt được độ tin cậy cao. Bài báo này đề xuất cơ sở xác định hệ số tổn thất cục bộ tại các hố ga để áp dụng trong tính toán, mô phỏng mạng lưới thoát nước mưa.

Authors: Phong Nguyễn Thanh
Published: September 2022

Một số nhà máy xử lý nước thải đã được đầu tư xây dựng ở Việt Nam hiện nay đang gặp phải hai vấn đề: Nhiều nhà máy hoạt động không hết công suất do không thu gom được lượng nước thải đưa về trạm xử lý; Một số nhà máy có nồng độ BOD đầu vào thấp do tiếp nhận nguồn nước thải từ cống bao gom nước thải và nước mưa đợt đầu từ cống thoát nước chung, trong đó lượng nước thải sinh hoạt phần lớn đều đã được xử lý sơ bộ qua bể tự hoại. Như vậy việc xây dựng các tuyến cống thu gom và kết nối thiết bị nước thải hộ gia đình cần được triển khai đồng bộ khi xây dựng nhà máy xử lý nước thải. Việc ứng dụng các thiết bị công nghệ mới  sẽ góp phần đơn giản trong việc xây dựng, dễ dàng trong việc duy tu bảo dưỡng mạng lưới cống gom nước thải đấu nối từ hộ gia đình
