Published: June 2024

Musculoskeletal disorders (MSDs) are a serious public health issue in both industrialized and developing countries. This study aims to investigate the prevalence of musculoskeletal symptoms and the association between working conditions and MSDs among female garment workers in Khan Mean Chey, Phnom Penh city, Cambodia. A cross-sectional research design was conducted among 423 female garment workers. Data collection was convenient sampling through face-to-face interview using a structured questionnaire consisted of socio demographics, working conditions, and the Standardized Nordic Questionnaire for musculoskeletal symptoms assessment during the period between April and May 2022. Descriptive statistics was used to present the prevalence of MSDs. Chi-square and fisher exact test were used to examine the association between working conditions and MSDs. Variables with a p-value<0.05 was taken as statistically significant. Participants’ median (±SD) age was 33 (±8.12) years. Most of them graduated primary school was 51.8% with normal BMI (68.3%). The findings revealed that the most frequently affected regions were reported in the shoulder, followed by neck, and lower back, respectively. Among 70.7% of female garment workers with MSDs reported at least one musculoskeletal symptom during the previous 7 days and 12 months. In the previous 7 days, there were significant association between MSDs and exercise (p=0.044), medical condition (p=0.001), head position during working (p=0.011), temperature (p=0.035), and work’s heavy (p=0.014). In the previous 12 months, there were significant association between MSDs and age (p=0.017), alcohol drinking (p=0.016), chair without backrest (p=0.042), temperature (p=0.019), noise (p=0.003), not getting enough rest (p=0.046), and get pressure from manager (p=0.004). MSDs was commonly reported in shoulder, neck, and lower back, and was statistically significantly associated with working conditions. Ergonomic interventions are needed to improve workstation design, appropriate working posture, workplace behavior, work stress, work-rest cycle, and work environment among female workers in the garment industry.

Authors:   , Islamiati Dian 
Published: June 2024

Heavy metal pollution is still one of the environmental problems globally, including Indonesia. One of these contaminations comes from agricultural products such as rice. Heavy metal contamination in rice is known to cause various health problems. This study aimed (1) To find Heavy metals concentration in Indonesian local rice (2) To find Non-cancer risk related to heavy metals contaminations in rice (3) To find cancer risk related to heavy metals contaminations in rice (4) To find association between associated factors with risk related to heavy metals contaminations in rice. The rice was collected from the 3 biggest local markets in Palembang, Indonesia. The total sample of rice was 6 samples with 2 types of rice, namely Pandan Wangi rice and Pulen rice. Rice was collected 100 grams per sample and then figured out the concentrations of As, Cd, Pb, and Cu by the ICP analysis. In addition, respondent data was obtained using an online questionnaire. The results of this study indicated that the concentrations of all heavy metals were lower than safety standard for food. However, the health risk assessment showed Non-cancer risk for both types of rice according to the high consumption rate. The average HI was 1.38+0.70 (ranged 0.16 to 3.93) for Pandan Wangi rice, and 1.53+0.78 (ranged 0.18 to 4.36) for Pulen rice. Similarly for cancer risk, the average TCR was 3.10 x 10-3+1.5 x 10-3 (ranged 3.79 x 10-4 to 8.80 x 10-3) for Pandan Wangi rice, and 2.76 x 10-3+1.5 x 10-3 (ranged 3.38 x 10-4 to 7.84 x 10-3) for Pulen rice. For the Chi-square results, the significant associated factors of health risk were age, BMI, source of drinking water, and source of water for cooking (p<0.05). Risk prevention must be carried out to reduce potential risks that may occur in the future by decrease the consumption rate. Moreover, minimizing the use of pesticides and chemical fertilizers can be an effort to reduce contamination in the paddy fields also agricultural products.

Published: June 2024

Civil society is built on an energy resource. It is very essential for the survival of the modern world and it affects every aspect of life. To form steam from boiling water, nuclear power is a clean and efficient way. The steam generated turns turbines to produce electricity. In nuclear power, the radiation released into the environment is lesser as compared to any other major source of energy. Studies have been done that indicated that major industrial accidents are more destructive than the worst possible accident at a nuclear plant. Nuclear power is one of the few commercially tested sources of energy that is virtually free of greenhouse gas emissions. This automatically makes it of interest to climate change pundits. This article explores nuclear energy as an alternative source of energy and explains the process of nuclear fission, nuclear reactions, nuclear fuel, various nuclear reactor types, operations involved in nuclear reactors, the nuclear fuel cycle, the fueling of nuclear reactors, and fusion power.

Published: June 2024

CQDs, characteristically quasispheroidal carbon nanoparticles composed of amorphous to crystalline carbon base, is a prospective semiconductor quantum dots owing to its excellent optical absorptivity, chemical stability, nontoxicity, and facile synthesis. In this study, we demonstrated the impregnation method to integrate CQDs, formed from chitosan with MIL-101(Cr) from terephthalic acid recycled by PET waste to synthesize CQDs/MIL-101(Cr) nanocomposite. After the hybridization of CQDs with MIL-101(Cr), the band gap energy of the 50% CQDs/MIL-101(Cr) has the lowest Eg (1.98 eV), allowing the demonstration of photocatalytic activity under high visible light. This material was tested in the photodegradation RR-195 dye and compared with the pristine components. The highest RR-195 degradation efficiency was recorded when using catalyst mass: 50 mg of 50% CQDs/MIL-101(Cr) catalyst samples, dye concentration: 50 ppm after 4 h under xenon lamp 300w was 96%. These results could promote a new material as a new semiconductor that can be used to protect water from further pollution.

AbstractClofarabine has been shown to be effective in AML patients, either as single agent or, mainly, in association with intermediate dose cytarabine. Based on these reports, we conducted a preliminary study combining clofarabine and intermediate dose cytarabine in AML patients who relapsed or failed to respond to at least two induction therapies. We treated 47 patients affected by relapsed/refractory AML with a regimen including clofarabine at 22.5 mg/m2 daily on days 1–5, followed after 3 hr by cytarabine at 1 g/m2 daily on days 1–5. Ten patients received a further consolidation cycle with clofarabine at 22.5 mg/m2 and cytarabine at 1 g/m2 day 1–4. Among the 47 patients, 24/47 (51%) achieved a complete remission, 5/47 (10.5%) a partial response, 10/47 (21%) had a resistant disease, and 6/47 (13%) died of complications during the aplastic phase. The most frequent nonhematologic adverse events were vomiting, diarrhea, transient liver toxicity, febrile neutropenia, and infections microbiologically documented. Among the 24 patients who obtained a CR 13 underwent allogeneic bone marrow transplantation. In 14 patients, complete remission duration was shorter than 12 months, whereas 10 patients experienced longer complete remission duration. These very preliminary results suggest that clofarabine‐cytarabine regimen is effective in this particularly poor prognosis category of patients, representing a potential “bridge” toward bone marrow transplant procedures. Safety data were consistent with previously reported salvage therapies. Further studies and a longer follow up are warranted. Am. J. Hematol., 2012. © 2012 Wiley Periodicals, Inc.
A Density Functional Theory Investigation of the Cobalt‐Mediated η5‐Pentadienyl/Alkyne [5+2] Cycloaddition Reaction: Mechanistic Insight and Substituent Effects
Authors: Ylijoki Kai E. O. , Budzelaar Peter H. M. , Stryker Jeffrey M. 
Published: July 2012

AbstractAlkyl‐substituted η5‐pentadienyl half‐sandwich complexes of cobalt have been reported to undergo [5+2] cycloaddition reactions with alkynes to provide η2,η3‐cycloheptadienyl complexes under kinetic control. DFT studies have been used to elucidate the mechanism of the cyclization reaction as well as that of the subsequent isomerization to the final η5‐cycloheptadienyl product. The initial cyclization is a stepwise process of olefin decoordination/alkyne capture, CC bond formation, olefin arm capture, and a second CC bond formation; the initial decoordination/capture step is rate‐limiting. Once the η2,η3‐cycloheptadienyl complex has been formed, isomerization to η5‐cycloheptadienyl again involves several steps: olefin decoordination, β‐hydride elimination, reinsertion, and olefin coordination; also here the initial decoordination step is rate limiting. Substituents strongly affect the ease of reaction. Pentadienyl substituents in the 1‐ and 5‐positions assist pentadienyl opening and hence accelerate the reaction, while substituents at the 3‐position have a strongly retarding effect on the same step. Substituents at the alkyne (2‐butyne vs. ethyne) result in much faster isomerization due to easier olefin decoordination. Paths involving triplet states do not appear to be competitive.

AbstractBackground:Patients with paroxysmal atrial fibrillation (AF) experience impaired quality of life (QoL) and psychological distress. Catheter ablation of AF can markedly improve QoL. However, the effect of catheter ablation of AF on psychological status is unknown.Hypothesis:Depression, anxiety, and QoL improve after catheter ablation in patients with paroxysmal AF.Methods:A total of 166 consecutive patients with symptomatic paroxysmal AF were examined. Eighty‐two patients (55 men, mean age 55.9 ± 6.1 y) underwent catheter ablation and 84 patients (58 men, mean age 57.2 ± 5.4 years) received antiarrhythmic drug (AAD) therapy. The Self‐Rating Depression Scale, Self‐Rating Anxiety Scale, and Medical Outcomes Survey 36‐item Short‐Form questionnaires were completed by these patients at baseline, and at 3, 6, 9, and 12 months of follow‐up. Results in the ablation group were compared with those of the AAD group.Results:In the ablation group, 42.7% of patients showed symptoms of depression and 37.8% showed symptoms of anxiety, which were similar to those in the AAD group. Both groups similarly displayed reduced physical and mental QoL. Catheter ablation was effective in reducing symptoms of depression and anxiety and improving QoL, and it was superior to AAD therapy (all P < 0.001). Multiple regression analysis demonstrated that catheter ablation, no AF recurrence, avoidance of warfarin use, higher baseline depression and anxiety scores, and lower baseline QoL scores contributed to improvement of depression, anxiety, and QoL, respectively.Conclusions:Catheter ablation is more effective for improving depression, anxiety, and QoL in patients with paroxysmal AF compared with AAD therapy.

Published: July 2012

AbstractWe report the synthesis and biological evaluation of a new series of oligosquaramide‐based macrocycles as anticancer agents. Compound 7, considered as representative of this series, exhibited significant antiproliferative activity against the NCI‐60 human tumor cell line panel, with IC50 values ranging from 1 to 10 μM. The results show that sensitivity to cyclosquaramides is clearly dependent on cell type, underscoring a degree of biological selectivity. The observed antiproliferative effects appear to be related to deregulation of protein phosphorylation, as compounds 7 and 8 are effective inhibitors of several important kinases such as ABL1, CDK4, CHK1, PKC, c‐MET, and FGFR, among others. The corresponding acyclic oligosquaramides and smaller cyclosquaramides did not show antitumor activity, suggesting that a macrocyclic structure with minimal molecular size plays a key role in the observed antitumor activity.
Backfilling with guarantees made as jobs arrive

Published: July 2012

SUMMARYIn this paper, we present scheduling algorithms that simultaneously support guaranteed starting times and favor jobs with system‐desired traits. To achieve the first of these goals, our algorithms keep a profile with potential starting times for every unfinished job and never move these starting times later, just as in Conservative Backfilling. To achieve the second, they exploit previously unrecognized flexibility in the handling of holes opened in this profile when jobs finish early. We find that, with one choice of job selection function, our algorithms can consistently reduce average waiting time and average bounded slowdown relative to Conservative Backfilling while still providing a guaranteed start time to each job as it arrives. In fact, in most cases, the algorithms give better performance than the more aggressive Extensible Argonne Scheduling System (EASY) backfilling algorithm, which does not provide guaranteed start times. Alternately, with a different choice of job selection function, our algorithms can focus the benefit on the widest submitted jobs, the reason for the existence of parallel systems. In this case, these jobs experience significantly lower waiting times than Conservative Backfilling with minimal impact on other jobs. Copyright © 2012 John Wiley & Sons, Ltd.

Published: July 2012

SUMMARYWe show a parallel implementation and performance analysis of a linear octree‐based mesh generation scheme designed to create reasonable‐quality, geometry‐adapted unstructured hexahedral meshes automatically from triangulated surface models. We present algorithms for the construction, 2:1 balancing and meshing large linear octrees on supercomputers. Our scheme uses efficient computer graphics algorithms for surface detection, allowing us to represent complex geometries. An isogranular analysis demonstrates good scalability. Our implementation is able to execute the 2:1 balancing operations over 3.4 billion octants in less than 10 s per 1.6 million octants per CPU core. Copyright © 2012 John Wiley & Sons, Ltd.

Published: July 2012

AbstractThe chalcopyrite CuInS2 thin film was fabricated at 500 °C for 2 h by sulfurization of Cu‐In layers (as precursors) that were sulfurized in a glass tube with pure sulfur powder. The structural, morphological, and optical properties of CuInS2 thin films are characterized using X‐ray diffraction (XRD), field‐emission scanning electron microscope (FE‐SEM), and UV/Visible/NIR spectrophotometer. The study of UV/Visible/NIR absorption shows the band gap energy value of CuInS2 thin films is 1.5 eV. The XRD pattern shows the film is pure CuInS2; no other peaks, such as CuS or CuIn5S8 were observed. Furthermore, the surface of the CuInS2 film is compact characterized by FE‐SEM, which also shows the disappearance of CuS on the surface at 500 °C.

AbstractMg:Ru:Fe:LiNbO3 crystals with various doping concentration of MgO have been grown by Czochralski method. The type of charge carriers and photorefractive properties in Mg:Ru:Fe:LiNbO3 crystals were measured by two‐wave coupling method using Kr+ laser (476 nm) and He‐Ne laser (633 nm) as light sources. We found that holes were the dominant charge carriers under blue light irradiation while electrons were the dominant charge carriers under red light irradiation. Mg2+ ions behaved no longer as damage resistant, but promoter to the photorefractive properties at 476 nm wavelength. The photorefractive properties under blue light improved with the increase concentration of Mg2+ ions. The enhancement mechanisms of the blue photorefractive were suggested. Experimental results definitely showed that Mg‐doped two‐centre Ru:Fe:LiNbO3 was a promising blue photorefraction material for holographic volume storage.
