A party to the charter will not be able to rely upon the doctrine of frustration if an event which makes further performance impossible has been caused by his breach of the charter. Strictly speaking, this is not a situation of frustration at all but rather a case of discharge of the contract by breach. In the Sea Angel case, the defendant entered into a Lloyd's Standard Form of Salvage Agreement with owners of the casualty on the LOF 2000 form, incorporating the SCOPIC clause. The time charter was on the terms of the Shelltime 4 form. This case the trial of the action brought by the claimants owners of the vessel Sea Angel claiming outstanding hire from the defendant charterers. This Case was issued whether charterparty frustrated by refusal of port authorities to issue "No Demand Certificate" allowing port clearance pending payment of oil spillage clean-up costs. The court concluded that no attempt had yet been made to invoke the assistance of the Pakistani court to obtain the release of the vessel. There was not so radical or fundamental a change in the obligation assumed by defendant as to establish frustration. The purpose of this study aims to analyse frustration and time charter in the Sea Angel case.

Investors from the whole world are looking for those stock markets that are less affected by interest rates. Pakistan is a good place to invest and the investors from the whole world are considering Pakistan for future ventures. The current study, therefore, aims to analyze the factors affecting investors' decision making in Pakistan with the interaction effect of locus of control. The primary data are gathered from 300 respondents. Structural equation modelling (SEM-PLS) is used to analyze the interactions among variables. The study finds positive impact of availability and representative biases on investment decision making. The study could not find any moderating role of locus of control. The results imply that decisions made by Pakistani investors are driven by the most easily or currently available information and they trust on the information obtained from family and friends without any authentication and verification. One possible description of insignificant moderation effect of locus of control can be the sample traits used in the study, e.g., personal characteristics, that change from culture to culture. Another description of these findings may be the association between heuristic biases, including availability, representative and psychological biases and decision-making regarding investment is not personality specific.

Purpose: Mid-upper-arm circumference (MUAC) is considered an alternative screening method for obesity. The aims of this investigation were to examine the ability of MUAC to correctly identify children with elevated body mass index (BMI) and to determine the best MUAC cutoff point for identification of children with high BMI. Methods: Anthropometric measurements (height, weight, and MUAC) from a cross-sectional sample of 7,921 Pakistani children aged 5-14 years were analyzed. Pearson correlation coefficients between MUAC and other anthropometric measurements were calculated. Receiver operating characteristic curve analysis was used to determine the optimal MUAC cutoff point for identifying children with high BMI. Results: Among 7,921 children, the mean (${\pm}$standard deviation) age, BMI, and MUAC were 10.00 (${\pm}2.86years$), 16.16 (${\pm}2.66kg/m^2$), and 17.73 (${\pm}2.59cm$), respectively. The MUAC had a strong positive correlation with BMI. The optimal MUAC cutoff points indicating elevated BMI in boys ranged from 16.76 to 22.73, while the corresponding values in girls ranged from 16.38 to 20.57. Conclusion: MUAC may be used as a simple indicator of overweight/obesity in children, with reasonable accuracy in clinical settings.

Background: Classical Hodgkin's lymphoma (cHL) is a B-cell lymphoid neoplasm characterized by a distinctive biological behavior with potentially curable disease characteristics. It is an uncommon hematological malignancy which primarily affects younger individuals. The rationale of this study was to determine its clinico-hematological profile along with stage stratification in Pakistani patients. Materials and Methods: In this descriptive study, adult patients with Hodgkin's lymphoma were enrolled from January 2010 to December 2014. Results: Sixty two histopathologically confirmed cases of cHL were identified. There were 42 males and 20 females, with a male to female ratio of 2: 1. The mean age was $29.7{\pm}13.8$ years with the median age of 30 years. B symptoms were present in 72.5% of patients. Histopathologically, the mixed cellularity type constituted 62.9% of cases, followed by nodular sclerosis in 25.8%, lymphocyte predominant in 9.6% and lymphocyte depleted in 1.6%. Stages I and II were present in 43.5% of patients at disease presentation, with 56.4% in stages III and IV. Conclusions: Our analysis shows that clinico-pathological features of Hodgkin's lymphoma in Pakistan are comparable to published data. Mixed cellularity is the commonest histological variant and advanced stage at presentation are common findings in our patients.

Background: Acute myeloid leukemia is an acquired clonal heterogeneous stem cell disorder. Hence, various parameters are sought out to categorize this disease into subtypes, so that as a consequence specific treatment modalities can be offered. Conventionally, the practically used method for classification utilizes French American British (FAB) criteria based on morphology and cytochemistry. The aim of present study was to determine the current spectrum of AML sub types in patients in Karachi. Materials and Methods: This single centre cross sectional study was conducted at Liaquat National Hospital, Karachi, extending from January 2010 to December 2014. Data were retrieved from archives were analyzed with SPSS version 22. Results: A total of 125 patients were diagnosed at our institution with de novo AML during five years period, 76 males and 49 females. Median age was 34.5 years. AML-M1 was the predominant FAB subtype (23.2%) followed by M2 (18.4%), M3 and M4 (16% each), M0 (14.4%), M5 (7.2%), M6 (3.2%) and M7 (1.6%). Conclusions: AML in Pakistani patients is seen in a relatively young population. The most common FAB subtype observed in our study was acute myeloblastic leukemia, without maturation (M1).

Background: Gradual loss of cytokeratin 13 (CK13) may be linked with the severity of dysplastic changes and transformation to malignancy. In this study we assessed the differential expression of CK13 in normal, hyperplastic, dysplastic and cancerous oral mucosa. Materials and Methods: A total of 93 oral biopsies were collected during the 2011-2014 period. The biopsies were characterized as normal (19), hyperplastic (21), severely dysplastic/carcinoma in situ (16) and invasive oral squamous cell carcinoma (OSCC) (37) after morphological assessment. Formalin fixed paraffin embedded sections were stained with a monoclonal antibody against CK13 using the Envision technique. Immunohistochemically stained slides were then analyzed for CK13 expression. Results: CK13 was consistently and diffusely expressed in all normal and hyperplastic tissue biopsies from oral mucosa. Severely dysplastic/carcinoma in situ biopsies showed complete loss in 50% of cases, while in the remaining 50% expression was very focal and weak. OSCC cases showed complete or near complete loss of CK13 in all cases. Few cases showed weak expression in keratin pearls only. Conclusions: This study validates the utility of CK13 IHC as a useful immunohistochemical marker in routine diagnostic practice to make distinction between non-neoplastic from dysplastic and neoplastic (malignant) oral lesions.

Performance data (from 1985 to 2000) of Jersey cattle imported from USA and maintained at Islamabad, Pakistan were evaluated. The purpose of this study was to assess the genetic merit of Jersey breed under Pakistani environment for further propagation. Cows with at least two calvings were considered for this study; records on 50 daughter-dam pairs were available on production and reproduction performance traits for genetic evaluation. The average age at first calving in parents was $25.2{\pm}2.4$ m as compared to $23.9{\pm}6.6$ m in progeny. Calving interval in parents and progeny was $416{\pm}74$ and $446{\pm}105$ d; lactation length $301{\pm}51$ and $325{\pm}73$ d; lactation milk yield $2,908{\pm}669$ and $2,707{\pm}903$ lit respectively. All these differences were found to be statistically significant except lactation length. The correlations between age at first calving and total lactation milk was -0.25, between calving interval and total lactation milk yield was 0.14, and between lactation length and total lactation milk yield was 0.79. The $h^2$ of these traits were low indicating important role of environment in expressing the genetic potential of animals. The S.E of $h^2$ of all the traits was high due to large variation in data.

Thirty-seven strains of Bacillus thuringiensis were isolated from Korean soil and examined for H-antigen serotyping, toxicity, and different spectra of biological activities. The isolate HL-175 bore a specific H-antigen, different from the 51 known serotypes, a spherical $\delta$-endotoxin crystal, and minor different biochemical characteristics. It was resistant to ampicillin, colistin, and penicillin G. Therefore, it was classified as a new serotype, H52, with the name kim. The other 36 isolates also produced endotoxin crystals and endospores. The crystal shape of eight strains was cuboidal while the others were bipyramidal. Biochemical characteristics of the isolates were only slightly different from the known serotypes of B. thuringiensis. The flagellar (H) antigens of the 36 isolates were identified as: one colmeri (H21), three galleriae (H5a,5b); two pakistani (H13); one toumanoffi (H11a, 11b); and twenty-nine kurstaki (H3a,3b). All 36 isolates were resistant to ampicillin, colistin, penicillin, cephalothin, and chloramphenicol.

Silajit is a blackish brown pitch-like gummy substance. It is an important Unani and Ayurvedic medicine widely used in the treatment of many diseases and as nutritional supplement It is found in certain mountainous regions of Pakistan, Afghanistan, India, Nepal, Australia and Russia. Silajit samples of Pakistani origin were obtained from different sources and analyzed for their physical characteristics and biochemical & elemental composition. X-ray diffraction studies on Silajit showed that it is an amorphous substance and has no crystalline structure. Also, pH studies of Silajit (2 g/L of water) indicated that it was slightly acidic in nature and ranged from 3.45 to 7.23. Conductivity ranged from 157.7 to 330. Amino acid analysis revealed that Silajit contained lysine and alanine in higher amounts than all other amino acids and ranged from 1456 to 2240 and 68 to $1615{\eta}mole/g$, respectively. Mean concentration of arsenic, mercury, cadmium, lead, copper and zinc was 73.15, 104.92, 0.496, 3.89, 4.04 and 17.23 ppm, respectively. Silajit samples were also analyzed for calcium, potassium and sodium.

This study investigates the current status and dyeing properties of various natural indigo powder dyes in the domestic market. Products from India, China, Europe are sold in the market and only a few manufacturers provide recommendation for the method of dyeing and information on the additives. Through the market research and the preliminary investigation on 21 products, 11 were selected for the dyeing experiment which include 3 Indian, 3 Chinese, 2 German, and 1 Pakistani origin indigo reduced powders, and 2 Indian origin dried indigo leaf powder. The two dyeing methods used were the precipitation method and the fresh juice method, both at $10^{\circ}C$, $25^{\circ}C$, and $60^{\circ}C$. Color difference, K/S value, and colorfastness of dyed cotton fabrics were examined. Indian reduced indigo powder showed the highest K/S value, deep dyeing, and the best color fastness. Chinese reduced indigo powder resulted in a more greenish and bluish color. Powders of dried indigo leaves were easy to use but resulted in a pale color due to low dye uptake.
