Authors: Rismayanti Rismayanti , Hutabarat Heny Agnesia , Alpiah Dini Nur 
Published: May 2024

Frozen shoulder is shoulder joint pain that occurs at an average age of 40-70 years with a prevalence of 3% of the general population in Indonesia. Trangutansus Electrical Nerve Stimulation (TENS) is a therapeutic modality using electric current which is able to stimulate the nervous sytem. This research aims to determine the effectiveness of (TENS) in frozen shoulder sufferers. Literatur review research was carried out using PICO search in databases such as Googke Scholar. There were 4 journals that met the criteria and showed the results that TENS was carried out twice a week, with a duration of 10-15 minutes and applied in continuous mode for 1 month with a p-value<0.05 shows a significant effect on reducing pain when carrying out daily activities such as washing clothes, combing hair, and picking up items from high places. So the author can conclude that TENS is effective in reducing pain and can also increase the joint range of motion (ROM) in the shoulder

Az M5 és az M43 autópálya építéséhez kapcsolódóan 2003–2004-ben feltárásokat végeztek a szegedi Móra Ferenc Múzeum régészei Mészáros Patrícia, Paluch Tibor és Szalontai Csaba vezetésével Szeged-Kiskundorozsma-Tóth János dombja I. lelőhelyén (26/66; M5 Nr. 60 = M43/2; ID 34668), melynek során egy késő vaskori település nyomai is előkerültek. A hét, félig földbe mélyesztett épületből és gödreikből álló megtelepedés a Maty-ér ága mellett található, a környezetéből kiemelkedő kisebb magaslaton. A vízfolyás mentén, egymástól 1-2 km távolságra további késő vaskori települések sorakoznak. A Maty-ér meghatározó szerepet játszott az itt élő közösségek életében, hiszen élővilága fontos élelemforrásként, különböző ágai pedig kommunikációs és védelmi vonalként is funkcionáltak. A három jól elkülöníthető épületcsoportba rendeződő, falusias jellegű települést az LT (B2)–C időszakban használhatta az itt élő közösség. Mindössze a 437. objektumban volt megfigyelhető padlómegújítás, ami a terület hosszabb használati idejére utalna. Az edények megoszlása kapcsán szintén külön figyelmet érdemel a fenti objektum, ahonnan a lelőhelyen talált grafitos szitulák közel fele került elő hat darab kisméretű grafit társaságában. A grafit jelenléte alátámasztja azt a felvetést, miszerint nem az edényekkel, hanem magával a nyersanyaggal kereskedtek a korszakban. Az OBJ. 393 jelzésű épületből egy sütőkemence maradványai mellett egy in situ feltárt, besimított hálómintával és felfényezett sávokkal díszített doliumot dokumentáltak (13. kép b). Az edénytípust elsősorban a késő La Tène-kor hagyatékénak gondolta a kutatás, de ma már korábbi megjelenésükkel is számolunk. A lelőhelyen feltárt edényt egy korai példánynak kell tekintenünk. A kézzel formált és korongon készült edények kivitelezése és aránya jól illeszkedik az alföldi lelőhelyeken megfigyelt tendenciákba. A kerámia leletanyag magán hordozza mind a Vekerzug-, mind pedig a La Tène-kultúra formai hagyatékának jegyeit, ennek alapján egy békés kelta−szkíta együttélés vázolható fel.

Authors: Mwatawala Hija Walad , Kapene Tumaini Daniel 
Published: May 2024

Aims: This study aimed at assessing the perceived quality of free health services and satisfaction amongst elderly people.
Study Design: Cross-sectional research design was employed.
Place and Duration of Study: Study was conducted in Dodoma District, Tanzania from September – November 2023.
Methodology: A cross-sectional design was adopted in the study. Purposive and simple random sampling techniques were used to select 134 elderly from the study area. Data was collected using questionnaires through interviews. The SERVQUAL model was employed, looking at the gap score of five dimensions (tangible, reliability, responsiveness, assurance, and empathy). Data were analysed using IBM Statistical Package for Social Sciences Statistics software.
Results: Majority (57.5%) of elders are aware of free health services and 66.4% of them accessed services. Elderly’s perceptions were lower than their expectations (gap = -1.70). Gaps for five dimensions of SERVQUAL model were: Tangibles (−2.21), reliability (−1.96), responsiveness (-1.76), assurance (-1.31) and empathy (-1.37).
Conclusion: Due to a negative overall mean score and the negative scores from all dimensions, it implies that the quality of free health services for elderly people in Dodoma district has not been satisfying to patients and needs to be improved.

Published: May 2024

Pulses is one of the important crops. Pulses has a high dietary value due to their high protein content. The pulse crop is primarily farmed for its grains, which are consumed whole or split (dal). Proper and timely planting has a significant impact on seed germination, plant growth, plant population in the field, and, eventually, overall production. In general, pulses are sown by animal/tractor drawn seed drill or manually. Tractor-drawn seed drills are best suited for medium to large farms with a high seed rate. Draft animals are not only growing more expensive, but they are also becoming scarce. More than 75% of Indian farmers are small and marginal farmers who perform all of their operations manually. Manual sowing is a highly labour intensive, tedious, time consuming and not technically suitable. Therefore, a double row ardiuno based battery operated seed sowing machine for pulses seed was developed and tested. During the study, the required physical property of chickpea seed was determined. The developed seed drill was tested for laboratory and field test. The overall size of developed seed sowing machine was 930×600×740 mm. It was operated through 24V (type Lead acid / li-ion) battery. A DC motor of 250 watt 24V was used as power source. Ground wheels have 15 lugs. It sowed seeds in two rows at a time. The overall weight of developed seed drill was 37 kg. In the laboratory test, seed rate, and mechanical damage of the developed seed sowing machine were 63.20 kg/ha, and 1.20% respectively. The overall performance of the developed seed sowing machine was found satisfactory. While in the field, draft of implement 37.19 kgf, missing index 2.46%, depth of seed placement 6.10cm, and draft of implement 14.51 kgf, missing index 3.63%, depth of seed placement 6.20 cm, The field efficiency of the developed seed sowing machine 83% respectively.
Comparison of the Decomposition of Static Interquark Potential in SU(3) Lattice Quantum Chromodynamics
Authors: Kandpal Chitra 
Published: May 2024

We study the decomposition of interquark potential and quantitatively compare the utility of V(r) \(\approx\) Vabel (r) + Voffdiag (r) and V(r) \(\approx\) Vmon(r) + Vmod(r) by calculating respective average relative deviation. We also study the slope of Vabel(r) and compare it with the slope of original SU(3) interquark potential over large distances so that we can study their exact confinement behavior. Remarkably, we found that for 244 lattice at \(\beta\) = 6.0, the sum of potentials Vmon(r) + Vmod(r) matches the original interquark potential V(r) more than Vabel(r) + Voffdiag(r). Comparing our results we found that perfect Abelian dominance is not seem to satisfy even for sufficiently large physical spatial volume (approximately larger than(2fm)3).

Published: December 2010

AbstractThe rapid synthesis of 2,4‐ and 2,5‐disubstituted oxazoles via metal‐catalyzed cross‐coupling reactions is reported. The 4‐ or 5‐position of the corresponding 4‐ or 5‐halogenated 2‐butylthiooxazoles was successfully functionalized via Suzuki–Miyaura, Sonogashira and Stille cross‐coupling reactions. The 2‐position of the 2‐butylthiooxazoles obtained was further coupled to various organozinc reagents through palladium‐ or nickel‐mediated cross‐coupling reactions.
Plastic Solar Cells: Interdiffusion of PCBM and P3HT Reveals Miscibility in a Photovoltaically Active Blend (Adv. Energy Mater. 1/2011)

AbstractDeveloping a better understanding of the evolution of morphology in plastic solar cells is the key to designing new materials and structures that achieve photoconversion efficiencies greater than 10%. In the most extensively characterized system, the poly(3‐hexyl thiophene) (P3HT):[6,6]‐phenyl‐C61‐butyric‐acid‐methyl‐ester (PCBM) bulk heterojunction, the origins and evolution of the blend morphology during processes such as thermal annealing are not well understood. In this work, we use a model system, a bilayer of P3HT and PCBM, to develop a more complete understanding of the miscibility and diffusion of PCBM within P3HT during thermal annealing. We find that PCBM aggregates and/or molecular species are miscible and mobile in disordered P3HT, without disrupting the ordered lamellar stacking of P3HT chains. The fast diffusion of PCBM into the amorphous regions of P3HT suggests the favorability of mixing in this system, opposing the belief that phase‐pure domains form in BHJs due to immiscibility of these two components.

AbstractOrganic bulk heterojunction photovoltaic devices predominantly use the fullerene derivatives [C60]PCBM and [C70]PCBM as the electron accepting component. This report presents a new organic electron accepting small molecule 2‐[{7‐(9,9‐di‐n‐propyl‐9H‐fluoren‐2‐yl)benzo[c][1,2,5]thiadiazol‐4‐yl}methylene]malononitrile (K12) for organic solar cell applications. It can be processed by evaporation under vacuum or by solution processing to give amorphous thin films and can be annealed at a modest temperature to give films with much greater order and enhanced charge transport properties. The molecule can efficiently quench the photoluminescence of the donor polymer poly(3‐n‐hexylthiophene‐2,5‐diyl) (P3HT) and time resolved microwave conductivity measurements show that mobile charges are generated indicating that a truly charge separated state is formed. The power conversion efficiencies of the photovoltaic devices are found to depend strongly on the acceptor packing. Optimized K12:P3HT bulk heterojunction devices have efficiencies of 0.73±0.01% under AM1.5G simulated sunlight. The efficiencies of the devices are limited by the level of crystallinity and nanoscale morphology that was achievable in the blend with P3HT.
Steady‐state process optimization with guaranteed robust stability under parametric uncertainty
Authors: Chang YoungJung , Sahinidis Nikolaos V. 
Published: December 2010

AbstractInterest in chemical processes that perform well in dynamic environments has led to the development of design methodologies that account for operational aspects of processes, including flexibility, operability, and controllability. In this article, we address the problem of identifying process designs that optimize an economic objective function and are guaranteed to be stable under parametric uncertainties. The underlying mathematical problem is difficult to solve as it involves infinitely many constraints, nonconvexities and multiple local optima. We develop a methodology that embeds robust stability constraints to steady‐state process optimization formulations without any a priori bifurcation analysis. We propose a successive row and column generation algorithm to solve the resulting generalized semi‐infinite programming problem to global optimality. The proposed methodology allows modeling different levels of robustness, handles uncertainty regions without overestimating them, and works for both unique and multiple steady states. We apply the proposed approach to a number of steady‐state optimization problems and obtain the least conservative solutions that guarantee robust stability. © 2011 American Institute of Chemical Engineers AIChE J, 2011
Numerical calculation and experimental validation of safety valve flows at pressures up to 600 bar

Published: December 2010

AbstractA numerical valve model has been validated to predict the discharge capacity in accordance to the requirements of valve sizing method EN ISO 4126‐1 and the opening characteristic of high‐pressure safety valves. The valve is modeled with computational fluid dynamics software ANSYS CFX, and the model is extended with the Soave‐ Redlich–Kwong real‐gas equation of state to allow calculations at pressures up to 3600 bar. A unique test facility has been constructed to perform valve function and capacity tests at operating pressures up to 600 bar with water and nitrogen. For gas flows, the numerical results and the experimental data on mass flow rates agree within 3%, whereas deviations in flow force are 12% on average. The inclusion of fluid‐structure interaction in the numerical method improves the results for the flow force well and also gives insight into the valve dynamics of an opening safety valve. In a comparison between the experimentally and numerically determined liquid mass flow rates, a model extension accounting for cavitation reduces overpredictions by a factor of 2–20% for smaller disk lifts and decreases the deviations in flow force from 35 to 7%. At higher disk lifts, the effect of cavitation is less, and experimental and numerical mass flow rates agree within 4% and flow forces within 5%. © 2011 American Institute of Chemical Engineers AIChE J, 2011
Arthrogryposis, perthes disease, and upward gaze palsy: A novel autosomal recessive syndromic form of arthrogryposis
Authors: Alkuraya Fowzan S. 
Published: December 2010

AbstractIn this article, the unusual combination of arthrogryposis, upward gaze palsy, and Perthes disease in two sisters and their cousin who are all part of an extended consanguineous Saudi family is reported. All patients had difficult to control bronchial asthma and subtle facial dysmorphism. Two of the three had pyloric stenosis, two were intellectually normal, and one had academic problems but had a history of birth hypoxia. Pedigree is consistent with an autosomal recessive mode of inheritance. Lack of previous reports suggests this represents a novel syndromic form of arthrogryposis. © 2010 Wiley‐Liss, Inc.

Published: December 2010

AbstractThe interparietal bone, Os Incae, is formed in a persistent mendosal suture. This suture is a normal variant in the human skull, well‐known in anatomy and radiology textbooks. We report 11 children with craniosynostosis in the presence of an interparietal bone, five from Children's Hospital at Montefiore and six children from Children's Hospital Boston. The true incidence of an interparietal bone in patients with craniosynostosis or craniofacial anomalies is not known; nor are there recognized sequelae of an interparietal bone (bathrocephaly). Hypotheses regarding mechanisms that may contribute to the formation of an interparietal bone are discussed. © 2010 Wiley‐Liss, Inc.

AbstractPoikiloderma with Neutropenia (PN), Clericuzio‐Type (OMIM #604173) is characterized by poikiloderma, chronic neutropenia, recurrent sinopulmonary infections, bronchiectasis, and nail dystrophy. First described by Clericuzio in 1991 in 14 patients of Navajo descent, it has since also been described in non‐Navajo patients. C16orf57 has recently been identified as a causative gene in PN. The purpose of our study was to describe a spectrum of C16orf57 mutations in a cohort of PN patients including five patients of Athabaskan (Navajo and Apache) ancestry. Eleven patients from eight kindreds were enrolled in an IRB‐approved study at Baylor College of Medicine. Five patients were of Athabaskan ancestry. PCR amplification and sequencing of the entire coding region of the C16orf57 gene was performed on genomic DNA. We identified biallelic C16orf57 mutations in all 11 PN patients in our cohort. The seven new deleterious mutations consisted of deletion (2), nonsense (3), and splice site (2) mutations. The patients of Athabaskan ancestry all had a common deletion mutation (c.496delA) which was not found in the six non‐Athabaskan patients. Mutations in the C16orf57 gene have been identified thus far in all patients studied with a clinical diagnosis of PN. We have identified seven new mutations in C16orf57 in PN patients. One of these is present in all patients of Athabaskan descent, suggesting that c.496delA represents the PN‐causative mutation in this subpopulation. © 2010 Wiley‐Liss, Inc.
Two organizing principles of vocal production: Implications for nonhuman and human primates
Authors: Owren Michael J. , Amoss R. Toby , Rendall Drew 
Published: December 2010

AbstractVocal communication in nonhuman primates receives considerable research attention, with many investigators arguing for similarities between this calling and speech in humans. Data from development and neural organization show a central role of affect in monkey and ape sounds, however, suggesting that their calls are homologous to spontaneous human emotional vocalizations while having little relation to spoken language. Based on this evidence, we propose two principles that can be useful in evaluating the many and disparate empirical findings that bear on the nature of vocal production in nonhuman and human primates. One principle distinguishesproduction‐firstfromreception‐firstvocal development, referring to the markedly different role of auditory‐motor experience in each case. The second highlights a phenomenon dubbeddual neural pathways, specifically that when a species with an existing vocal system evolves a new functionally distinct vocalization capability, it occurs through emergence of a second parallel neural pathway rather than through expansion of the extant circuitry. With these principles as a backdrop, we review evidence of acoustic modification of calling associated with background noise, conditioning effects, audience composition, and vocal convergence and divergence in nonhuman primates. Although each kind of evidence has been interpreted to show flexible cognitively mediated control over vocal production, we suggest that most are more consistent with affectively grounded mechanisms. The lone exception is production of simple, novel sounds in great apes, which is argued to reveal at least some degree of volitional vocal control. If also present in early hominins, the cortically based circuitry surmised to be associated with these rudimentary capabilities likely also provided the substrate for later emergence of the neural pathway allowing volitional production in modern humans.

Grooming network cohesion and the role of individuals in a captive chimpanzee group
Authors: Kanngiesser Patricia , Sueur Cédric , Riedl Katrin , Grossmann Johannes , Call Josep 
Published: December 2010

AbstractSocial network analysis offers new tools to study the social structure of primate groups. We used social network analysis to investigate the cohesiveness of a grooming network in a captive chimpanzee group (N = 17) and the role that individuals may play in it. Using data from a year‐long observation, we constructed an unweighted social network of preferred grooming interactions by retaining only those dyads that groomed above the group mean. This choice of criterion was validated by the finding that the properties of the unweighted network correlated with the properties of a weighted network (i.e. a network representing the frequency of grooming interactions) constructed from the same data. To investigate group cohesion, we tested the resilience of the unweighted grooming network to the removal of central individuals (i.e. individuals with high betweenness centrality). The network fragmented more after the removal of individuals with high betweenness centrality than after the removal of random individuals. Central individuals played a pivotal role in maintaining the network's cohesiveness, and we suggest that this may be a typical property of affiliative networks like grooming networks. We found that the grooming network correlated with kinship and age, and that individuals with higher social status occupied more central positions in the network. Overall, the grooming network showed a heterogeneous structure, yet did not exhibit scale‐free properties similar to many other primate networks. We discuss our results in light of recent findings on animal social networks and chimpanzee grooming. Am. J. Primatol. 73:758–767, 2011. © 2010 Wiley‐Liss, Inc.

Published: December 2010

AbstractThis study presents a description and comparative analysis of Middle Pleistocene permanent and deciduous teeth from the site of Qesem Cave (Israel). All of the human fossils are assigned to the Acheulo‐Yabrudian Cultural Complex (AYCC) of the late Lower Paleolithic. The Middle Pleistocene age of the Qesem teeth (400–200 ka) places them chronologically earlier than the bulk of fossil hominin specimens previously known from southwest Asia. Three permanent mandibular teeth (C1‐P4) were found in close proximity in the lower part of the stratigraphic sequence. The small metric dimensions of the crowns indicate a considerable degree of dental reduction although the roots are long and robust. In contrast, three isolated permanent maxillary teeth (I2, C1, and M3) and two isolated deciduous teeth that were found within the upper part of the sequence are much larger and show some plesiomorphous traits similar to those of the Skhul/Qafzeh specimens. Although none of the Qesem teeth shows a suite of Neanderthal characters, a few traits may suggest some affinities with members of the Neanderthal evolutionary lineage. However, the balance of the evidence suggests a closer similarity with the Skhul/Qafzeh dental material, although many of these resemblances likely represent plesiomorphous features.
