Increasing the imaging capabilities of multimode fibers by exploiting the properties of highly scattering media
We present a novel design that exploits the focusing properties of scattering
media to increase the resolution and the working distance of multimode fiber
based imaging devices. Placing a highly scattering medium in front of the
distal tip of the multimode fiber enables the formation of smaller sized foci
at increased working distances away from the fiber tip. We perform a parametric
study of the effect of the working distance and the separation between the
fiber and the scattering medium on the focus size. We experimentally
demonstrate submicron focused spots as far away as 800{\mu}m with 532nm light.Comment: 4 pages, 3 figure

Microteaching in Pakistan: Perspectives of Novice Higher Education Faculty about the Contribution of Microteaching to their Learning and Practice
This mixed-methods research documents the self-reports of novice higher education faculty of Pakistan about the contribution of the microteaching module of Master Trainer Faculty Professional Development Program (MT-FPDP) as well as the factors that either supported or hindered faculty in using their new knowledge and skills. My literature review on microteaching, which until recently had been a neglected field for two decades, includes higher education development needs as âadults-teaching-adults,â microteaching as a response to novice teaching issues, and a contextual analysis of the model in different settings. I analyze and interpret the findings using a conceptual framework that synthesizes adult learning, self-efficacy, and reflective practices. This research finds that the opportunities to practice their teaching skills, with an intentional reflective feedback mechanism, allowed the novice faculty to prepare themselves in a safe and collaborative environment during MT-FPDP. However, microteaching content, activities, and supplementary material were neither closely relevant to varied teaching contexts of Pakistan nor appropriate in its application at the higher education level. Moreover, the lack of supervisorsâ expertise to facilitate the microteaching processes, and mentor the novices discouraged the participation. Despite these hindrances, the novices reported behavior modification, self-efficacy, and use of reflective practices in their classrooms. However, discouraging organizational culture/policies, lack of collegial, administrative, and technical support, and geopolitical factors are the primary barriers to the implementation of the knowledge and skills. The Heads of Department (HoDs)/Deans confirmed the carryover from MT-FPDP to classroom teaching, and acknowledged these institutional supports and barriers. This research argues that the microteaching content and model must be adapted to the context of Pakistan, and the microteaching skills should be prioritized based on the higher education faculty needs. The Learning Innovation Division (LID) of the Pakistan Higher Education Commission (HEC) needs to appoint expert, unbiased, and culturally sensitive supervisors who can provide novices more self-directed, transformative, and reflective learning opportunities during MT-FPDP. LID/HEC should provide avenues for collaboration and coordination by establishing the informal âcommunities of practiceâ to foster collegial support within an institution and within a province

Development of Capecitabine Floating Tablet Dosage Forms for Treating Stomach Cancer
Objective: In the present research work, oral gastro retentive dosage forms (GRDFs) of capecitabine (CPC) were formulated using floating concept.
Methods: GRDFs were formulated using hydroxypropyl methyl cellulose (HPMC K4M and K15M) as drug release retardant, sodium bicarbonate (NaHCO3) and calcium carbonate (CaCO3) as gas generating agents, and micro crystalline cellulose (MCC), dicalcium phosphate (DCP), spray dried lactose (SDL), and pre gelatinized starch (PGS) as fillers. The tablets were prepared by direct compression method and evaluated for various parameters. The GRDFs were also characterized by Fourier-transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC).
Results and Discussion: All the formulations were subjected for pre and post compression parameters, shows all the data within the limits. The lag times of GRDFs has decreased significantly for formulations containing calcium carbonate when compared to sodium bicarbonate as gas generating agent. In vitro drug release studies indicate that higher polymer concentration delayed the CPC release, and the sustaining effect was in the order K4M > K15M > LVCR 100. Addition of MCC, DCP, SDL, and PGS as fillers further affected the lag time and in turn the CPC release rates.
Conclusion: The formulation (F9) containing 10%w/w HPMC K4M as the release retardant, microcrystalline cellulose as filler and 20%w/w CaCO3 as gas generating agent fulfilled regulatory requirements in terms of percent drug release at the end of 24h.

Evaluation of fungicides, biocontrol agents and botanicals for management of damping-off in cabbage seedlings caused by Fursarium moniliforme sheld
The antagonistic effect of 10 fungicides, four biocontrol agents and 10 locally available botanicals in controlling the growth and sporulation of Fusarium moniliforme in vitro were tested. A pot culture experiment was also conducted to study the effect of seed treatment and soil treatment alone or in combination on germination and seedling vigour of cabbage. In vitro evaluation of ten fungicides by poisoned food technique showed that all the fungicides efficiently inhibited complete inhibition of the linear growth of the fungus was observed with Thiophenate methyl, Carbendazim, Mancozeb, Difenconazole, Propiconazole, Hexaconazole, Sixer and Tricyclazole. Sporulation was completely inhibited by all the fungicides evaluated. In dual culture technique of the fungus and biocontrol agents, of the four biocontrol agents evaluated the antagonists, T. hamatum completely overgrew the pathogen, T. harzianum colonized on half of the growth of the pathogen, T. viride remained locked with the fungus at the point of contact and P. citrinum formed inhibition zone with the fungus. Sporulation was completely inhibited by all the four antagonists. Among the ten locally available botanicals tested by poisoned food technique in vitro, garlic extract showed maximum fungitoxic propertyfollowed wild sage (Lantana camara), onion (Allium cepa), neem (Azadirachta indica), goat weed (Ageratum conyzoides) and marigold (Tagetes erecta) . In pot culture experiment, the least disease incidence was recorded in soil treatment with carbendazim (26%) followed by T. harzianum (29%) and P. glabrum (29.7%). However,considering the various drawbacks and hazardous effects resulting from use of chemicals, biocontrol agents and plant extracts can be recommended to use in raising healthy seedlings free from pre- and post-emergence damping-off
Asset-building payments for ecosystem services:Assessing landowner perceptions of reforestation incentives in Lebanon
Aim of study: Incentivising landowners to supply ecosystem services remains challenging, especially when this requires long-term investments such as reforestation. We investigated how landowners perceive, and would respond to, distinct types of incentives for planting diverse native trees on private lands in Lebanon. Our aim was to understand landownersâ attitudes towards hypothetical Payments for Ecosystem Services (PES) contracts options; their likely participation; and the potential additionality they would provide.Â
Area of study: Highland villages situated within eight of Lebanonâs 20 Important Plant AreasÂ
Materials and methods: Mixed-methods surveys were conducted with 34 landowners to determine past, present and future land-use strategies. Study participants were presented with three differently structured reforestation contract options (or schemes). The three schemes (results-based loan, action-based grant, and results-based payments) differed in their expected risks and benefits to landowners. Qualitative debriefing questions followed each of the schemes presented.Â
Main results: Although the results-based loan did deter uptake relative to the lower risk action-based grant, results-based payments did not significantly increase uptake or planting area, suggesting asymmetric attitudes to risk. Qualitative probing revealed economic, social (e.g. trust) and institutional factors (e.g. legal implications of planting forest trees on private land) that limited willingness to participate in the results-based contract option.Â
Research highlights: This study demonstrates the importance of combining qualitative and quantitative methods to better understand landowner perceptions of incentives and risks, particularly in challenging socio-political contexts
Some Immunologic Evaluations of Toxoplasmosis in Iraqi Aborted Females
Forty-eight aborted women (Iraqi Arab Muslims) at the first trimester with a serological evidence of toxoplasmosis were investigated. Two age- and ethnic-matched control groups were included: 40 aborted women due to accidental events (Control I), and 40 unmarried (virgin) women (Control II). The subjects were evaluated for the following parameters: HLA-class I antigens (A, B and Cw), blood groups, total and differential counts of leukocytes, lymphocyte subpopulations (CD3+, CD4+ and CD20+ cells), phagocytosis of heat-killed yeast (phagocytic index and NBT index), and total serum levels of immunoglobulins (IgA, IgG and IgM) and complement components (C3 and C4). The HLA-A2 and -Cw8 antigens were significantly increased in the patients, while A3 antigen was significantly decreased. Blood group phenotypes in patients and controls also showed significant variations. The total and differential counts of leukocytes showed no significant differences between patients and controls, with the exception of lymphocytes, which showed a significant decreased count in the patients compared to control II. However, the lymphocyte subpopulations showed a significant increased percentage in patients. The phagocytic index was approximated in patients and controls, while NBT index was significantly decreased. Total serum level of IgG was significantly increased in the patients, while IgA, IgM, C3 and C4 levels did not maintain such variation
